What can be done with a building hair dryer. How to choose, why you need and where a building hair dryer is used Where a building hair dryer is used

This article will help novice craftsmen learn what can be done with a building hair dryer. This tool is a convenient supplier of extremely heated air, which comes out at a certain speed. The main scope of this device can be considered:

Softening paintwork materials to be withdrawn;
Welding of polyethylene films;
Bending of plastic building pipes;
Soft metal soldering and processing wooden products and materials.

In other words, with the help of this building element, you can perform great amount tasks that are considered an integral part of any construction process. Special attention It is worth paying attention to the convenience of using a hair dryer, but this will be discussed below.

Important! Do not use this tool for purposes that are not specified in such a document as a hair dryer: instructions.

Description of the workflow, as an instruction for beginners

So why do you need a building hair dryer? This tool is used in those works and places where it is required to use extremely heated air to act on structural characteristics certain type of material. The basic design of the tool is very similar to household counterparts that are used to dry hair.

Important! Do not use a building hair dryer to dry your hair, because the temperature of air heating in it exceeds all the norms of household appliances.

The construction hair dryer for paint removal has only two heating modes: 550 and 300 degrees. In other words, in order to select the desired air temperature, it is necessary to adjust the distance from heater to the working surface of the material. The farther the device is from the selected material, the lower the air heating temperature will be.

Nozzles and their meaning

Nozzles for a building hair dryer are quite important when working with certain types of material. Usually, standard equipment The tool has four nozzles, each of which is used for individual jobs. When using this equipment, you must be extremely careful when handling the tool. Important! After using a hair dryer with a nozzle, it is necessary to let it cool down so as not to spoil the material being processed.

Due to the fact that the nozzles are made of thin metals they heat up pretty quickly. Thus, before using a building hair dryer, it is worth remembering this small feature. If you put a hot hair dryer on work surface material, the nozzle may damage it. It is for this reason that the hair dryer must be allowed to cool or use a special metal stand.

Alternative application of the tool

How to work as a building hair dryer for household purposes? This question seems to be quite common. True, with this tool you can do a lot different work in particular, cook barbecue.

With help this machine can be quickly and easily reheated charcoal, avoiding the use of special firelighters and small brushwood. Coal heats up quite well, which is what all lovers of this dish want. Important! Do not heat the meat with a hair dryer, because this can affect the smell and taste of the dish.

The industrial hot air gun, also called construction hot air gun, is widely used in construction sites and is multifunctional tool. If you want to purchase such a tool, then you need to decide on its use - for the production of what kind of work and in what volumes it is planned to use it. You also need to be sure to familiarize yourself with its main technical characteristics. Before choosing a building hair dryer specific model, it is worth considering in detail all the types and qualities of this power tool. What we will do in this article, in which, together with the site, we will study all the varieties and characteristics of this tool.

How to choose a building hair dryer

How to choose a building hair dryer: varieties of this tool

There are two types of tools of this class - a professional construction hair dryer and a household one. The principle of operation of both types is the same, the difference between them is only in power and outlet air temperature. But the tasks and functions of these electrical appliances are completely different.

An ordinary household hair dryer is used for drying and styling hair, where the outlet temperature should not exceed 60 ° C. The building hair dryer, which we will talk about in this article, is outwardly similar to it, but this is only externally. The main difference between an industrial hot air gun and a household hot air gun is the scope of this device and its specifications, the main ones being heating and power.

Thanks to increased power, in comparison with household hair dryer(average 1.5 kW), the temperature of the building hair dryer at the outlet can reach up to 750˚С. Structurally, such a tool is an electrical appliance that incorporates a heat-resistant housing, powerful enough heating element and a high-speed fan that creates a continuous stream of hot air. Usually, a set of nozzles adapted to perform various tasks is supplied with an industrial hair dryer, which greatly expands the scope of this tool, raising it to a level of high versatility.

Commonly used nozzles for building hair dryers

As a rule, one or more special nozzles are supplied with a building hair dryer to perform various works. Some of them are specialized and are sold separately from the tool, so you need to be prepared for additional purchases.

The most widely used are the following nozzles for a building hair dryer:

1. Focusing round nozzle. It is used to seal a variety of cracks using welding plastic tape, soldering copper pipes in a contactless way, repair of boats, skis and so on.

2. Flat nozzle. It is used to remove old paint and wallpaper, film, as well as for controlled deformation of plastic, polystyrene boards and PVC products.

3. Welded mirror. It is used for flash butt welding of plastic parts - the joined parts reach the welding point, pressed against the welded mirror.

4. Welded nozzle. Its direct purpose is the connection of synthetic-based welding cables.

5. The wide jet nozzle is a kind of flat nozzle and is used to remove paint from large areas.

6. Glass protector. Special fixture designed for surfaces that do not withstand high temperature(for example, glass), is used to remove putty, varnish, paint from them.

7. Slotted or crevice nozzle. It is used for welding PVC-materials in the cap method.

8. Carved nozzle. Designed for straight and shaped foam cutting.

9. Reducer nozzle. This is an adapter for slotted and carved nozzles. In addition, it can be used for spot welding.

So, do you need an industrial hair dryer? Let's take another look at what he is capable of, and will his purchase be a waste of money?

Scope of building hair dryer

A construction hair dryer, the use of which is quite justified in construction, can be used to remove old coatings of walls, ceilings, doors and windows, defrosting water pipes, controlled deformation (bending), plastics, roofing material, soldering of awning and polypropylene fabrics. It is possible to use a building hair dryer as a blowtorch and even to light coals in the grill! Brief scope industrial hair dryer can be characterized as follows - it can be used wherever local heating of surfaces is required.

One of the main functional features of the building dryer is the presence of a smooth adjustment of the output temperature, which allows you to work with materials that have different melting points. There are models without smooth adjustment, but with several fixed temperature conditions. A building hair dryer with temperature control in this way loses in its capabilities to a tool with smooth temperature control.

Building hair dryer: application

All professional industrial hair dryers have a cold air function in their arsenal, which can be useful in many cases. It is better if the building dryer of your choice is equipped with a digital electronic display, which greatly simplifies some technological operations, for example, sealing joints heat shrink tubing. Naturally, the price of such an industrial hair dryer will be an order of magnitude higher. From a security point of view, it is essential to have protective cover, which, although it makes the device heavier, minimizes the risk of burns to a person or melting of the workpiece.

Well, in conclusion, I would like to add that the question of how to choose a building hair dryer is not purely individual - according to by and large, the difference between this tool lies solely in the temperature of the air heating. And nozzles that are fully responsible for its intended use can be purchased separately. First of all, the purchased hot air gun must be reliable and powerful.

A building hair dryer (also known as a "thermal gun" and "thermofen") is very similar in shape and design to an everyday device for styling and drying hair, but with slight differences. If you are planning a large-scale painting or installing plastic pipes, this device will become your reliable friend.

What is a building dryer for and what functions does it perform?

The thermal gun is more powerful than a hair dryer (930-2300 W), the temperature of the supplied air can reach 650 ° C, and the performance varies between 200-650 liters / min, depending on the model of the device and the tasks. But the range of tasks to be solved is limited only by the experience and ingenuity of a person using a hot air gun. Below are just a few possible options usage:

Drying surfaces.
Soldering of metal parts and details.
Increasing the temperature of metal joints before disassembling them.
Warming up adhesive mixtures before applying to the surface.
Heating up the bonding layer before separating the glued elements.
Welding and shaping of thermoplastic parts (for example, creating a bend or fitting plastic pipes).
Heating of varnish coatings and paint coatings for their subsequent removal.
Heating frozen water pipes.
Ignition of fires for a barbecue and a shish kebab.

Now it has become obvious that the main function of the building hair dryer is heating and preparatory. Working from the mains, the thermal gun has the advantage of flexible setting of hot air supply modes and does not need flammable fuel, gradually replacing the outdated blowtorch. And most importantly - do not try to make a stylish hairstyle with it or dry your pets, they will be very upset.

How to choose a building hair dryer?

Choosing a building hair dryer is not a difficult task, but it is very important when buying to pay attention to such parameters as:

Power (from 930 to 2300 W). The temperature level directly depends on the power, the more powerful the hair dryer, the faster the surface will heat up. For the same tasks, the resource will be higher for the tool with higher power. hot air guns high power increase the load on the network. Don't forget about it.

Power - key parameter when choosing a building hair dryer. It depends on him how quickly this or that task will be completed.

Maximum value operating temperature(up to 650 °C). The higher it is, the more versatile the device and the more functionality it has.
Temperature regulation. For simplicity, we can divide all technical hair dryers into two categories: building hair dryer with temperature control and with smooth temperature control. With the addition of one word, the difference between the two species becomes enormous. Models without smooth temperature control, as a rule, have only 2-3 modes of operation with a fixed temperature, allowing you to work in conditions of maximum, medium or minimum heating, narrowing functionality heat gun to almost a minimum, forcing you to accurately calculate the time and distance needed for a heat treatment. You'll have to get used to, spend time and nerves. To prevent this from happening, you should immediately focus on models with continuously variable temperature control, insuring yourself against cases where materials of the same type can have different melting temperatures.
The presence of a temperature maintenance system. Thanks to the temperature stabilization system, technical hair dryer keeps the heating level of the air flow at a stable height, regardless of the load. That is, with an increase in the strength of the air flow, the temperature remains unchanged. This indicator is directly related to the power of the device.
Overheating protection function. It will not allow the hair dryer to overheat or even catch fire in your hands during operation. But even if your hair dryer has such a function, you need to work only with heat-resistant gloves.
The minimum length of the cord should be at least 2.5 meters so as not to feel discomfort when working at full height.
Some models are equipped with LCD screens to display the operating temperature. The option is not so much mandatory as desirable. The prices of hot air guns with a screen can be significantly higher than without it, but the convenience of use also increases.
Depending on the model of the building hair dryer and the manufacturer, special nozzles are attached to it to expand the scope.

How to use a building hair dryer?

The scope of the building hair dryer is very wide., so each task has its own approach. Let's consider a few:

1. Removal of old paintwork. Easiest old paint removed from wooden surfaces. Harder to peel off paint hardware, due to the fact that the metal has a high thermal conductivity and partially dissipates directed heat. And real master class- removing paint plastic coatings and surfaces - requires considerable skill, precisely selected temperature and correct timing. All we need for work: a wide jet nozzle and a hot air gun itself.

Despite the ease of use, it is very important to observe safety precautions: do not remove thermal gloves and goggles during operation, work in ventilated areas away from flammable and combustible materials.

We put on goggles and thermal gloves (safety first!), set the hair dryer to the maximum operating temperature (depending on the model - from 500 to 650 ° C) and maximum air flow (up to 650 l / min). Next, direct the hair dryer to the area from which we want to remove the paint. The device must be kept at a distance of 2–3 cm from the surface to be treated and wait until the paint begins to “blow bubbles”, announcing its readiness to leave its familiar place. After that, you need to take a scraper or spatula and gently pry off the treated area. The paint will come off willingly, leaving no trace. After that, you can start processing a new zone. It is important to leave indents of a few centimeters between areas so that hot air does not enter the already treated area.

2. Jointing floor coverings. With the help of a building hair dryer, it is quite easy to weld the seams of several parts of the floor covering (PVC, linoleum, rubber) using a filler rope similar in composition. The filler cord is shaped like a thin pencil and must be identical in chemical composition to the parts to be welded. So, we adjust the two parts of the connecting coating close to each other, make a V-shaped hollow along the entire length of the seam with a special cutter, melt the filler cord with a slotted nozzle (used for cap welding of two parts of a homogeneous material) and fill the hollow. The operating temperature for the rope melt should be in the region of 300 °C. Excess connecting material is removed from the seam with a special crescent-shaped knife so that the surface of the coating becomes even.

3. Welding of plastic pipes. The popularity of a plastic pipeline is growing every day, and today it is no longer necessary to call craftsmen to create a water supply / drainage communication, modern tools allow you to do this at home. First, let's find a welded mirror (reflector attachment) in our kit. It is called a reflector because it prevents the welding object from sticking to the nozzle. In shape, it resembles a flying saucer: rounded and without any holes.

We attach the nozzle to the hair dryer, set the operating temperature to 200–300 ° C with a minimum air flow and leave it to heat up for a while. vertical position. When the required temperature is reached, the ends of the pipes are brought to both sides of the nozzle and slightly pressed. It is important to catch the moment when the plastic has become soft, take the pipes away from the reflector and connect them to each other. In this position, they must be held for 20-35 seconds, resulting in a strong connection.

4. Welding of film coatings. Film coatings are usually overlap welded, placing the welded parts so that one part overlaps the other within 2–4 cm. The operation lasts only a few seconds, and immediately after that working area must be rolled up. Be sure to check the junction for strength by trying to break the connecting seam. If the strength turned out to be unsatisfactory, it is worth raising the temperature and repeating the procedure.

The building dryer once again proves the old rule: "Simplicity is yours best friend", and the main limiter in its application is only your imagination.

A building hair dryer outwardly resembles a similar device, designed to dry hair in a short time. The key difference is that this hair dryer is used exclusively in construction. it indispensable assistant for any master who started the installation of plastic pipes, large-scale painting or any other event. Read more about where such a device is useful, as well as what to look for when buying - in today's article.

Dryer construction - what is it intended for I

The tool has several names, including "thermofen", as well as "thermal gun". Compared to a conventional household hair dryer, a hot air gun used in construction has a significantly higher power, performance and air supply temperature. The list of tasks performed by the tool is limited solely by the ingenuity and experience of the master in whose hands it is.

So, choosing this device, you can use it to perform the following tasks:

Soldering metal structures and their parts
Surface drying
Warming up the glue just before using it
Temperature rise metal parts before disassembly
Warming up the bonding layer to make it easier for you to unstick things
Heating of paint and varnish coatings for the purpose of their further elimination
Shaping thermoplastic elements, such as creating a fit or bend in a plastic pipe
Warming up water pipes that have frozen during the winter cold
Breeding fires for barbecues or barbecues - a building hair dryer copes well even with such a task.

As can be seen from the list above, the main purpose of the thermal gun is precisely to heat necessary elements. Quite deservedly, this device occupies a leading position in the ranking of the most useful tools Literally from the moment it was launched on the market building tools. He has long succeeded in replacing the blowtorch, which was previously used to perform similar operations. The hair dryer does not need fuel, it is able to change the modes of air supply. It is not surprising that the craftsmen try to purchase the hot air gun in the first place.

Choosing a building hair dryer - what we pay attention to

In any store construction equipment You can find many models of thermal guns. All of them differ in manufacturers, modifications, parameters, as well as cost. You will have to spend a lot of time to decide which building hair dryer you are going to choose.

1. Power is a key parameter. Typically, the figure varies from 930 to 2300 watts. Other parameters depend on the performance, including the air heating rate, as well as the temperature level of the device. Naturally, it is recommended to opt for powerful models. But at the same time, they put a serious load on the network, which should not be forgotten either.
2. The maximum value of the operating temperature. A value of 650 degrees is considered optimal; a hair dryer with this indicator is versatile and can perform a variety of jobs.
3. Temperature control. There are two types of adjustment - normal and smooth. In the first case, you can set only a few temperature values using the switch, as a rule, no more than four modes. Naturally, the functionality of the device immediately decreases, because it is necessary to accurately determine the distance and time of heating in order for the heat treatment to give the desired result. Experienced craftsmen buy a tool with continuously adjustable temperature, which allows you to set the optimal level of heating in this case.
4. Temperature stabilization system at the same level. Another one useful feature, the usefulness of which is very difficult to overestimate. The use of a system for maintaining the set temperature makes it possible to maintain the level of heating of the heat flow, regardless of factors external environment and loads. Again, this indicator depends on the power of the building hair dryer.
5. Overheat protection. A very important function, since the power tool is constantly exposed to huge thermal loads. However, you do not have to worry that the heat gun will fail or even catch fire during operation with this function. In any case, regardless of the model, power and heating level, all work is carried out exclusively in heat-resistant gloves and goggles.
6. Cord length. Since thermal guns work only from the mains, care must be taken that the model you purchased is equipped with a cord of sufficient length for comfortable operation. After all, it is the presence of sockets that is the main factor limiting the range of the device.
7. Nozzles. The kit comes with several nozzles that are suitable for most operations.
8. The next function is superfluous for most masters - this is an LCD screen where important parameters tool performance. Such a hair dryer can only afford professional builders, since the cost of an additional screen is very high, and the presence of this function is absolutely optional.

Building hair dryers do not belong to the category of cheap electrical appliances. The cost of the cheapest instruments does not exceed one thousand rubles. If you need a quality and reliable model famous brands, for example, Makita, Bosch, Black & Decker, Metabo, Hammer, then the amount may increase several times. The most advanced industrial models will cost several tens of thousands of rubles. In any case, you need to buy an electric hair dryer that meets your needs. You shouldn't pay a lot of money for features you'll never need.

How to use a thermal gun - features when performing various jobs

Having decided which building hair dryer you need, you need to learn how to work with the device correctly. As noted above, the thermal gun has a very wide scope. Let's highlight the main nuances when working with certain details. To begin with, we will tell you how to remove an old layer of paint or varnish from a surface. Easiest to clean wooden surface, here you can do with the usual improvised means. Metal is not so easy to clean from varnish, but the most difficult option is to remove paintwork with plastics.

Using a thermal gun, it is easy to remove paint or varnish from the surface

Putting on heat-resistant gloves and goggles, turn on the hair dryer in mode maximum temperature and maximum heat flux, after which we direct the muzzle of the gun to the surface area that we want to process. Keep the electric hair dryer at a distance of approximately 3 cm from the plastic. After a few minutes, the paint will begin to melt and bubble - this is a signal for us that we can proceed directly to its removal. Using a conventional spatula or scraper, the old layer is carefully removed. With the help of a hair dryer, you managed to clean the surface of the paint without any effort in a couple of minutes, while by conventional means it could take more than one hour. And the result would be far from ideal.

Power is the main indicator when choosing a hair dryer, the speed of all work depends on the power.

Another thing you need a hot air gun for is to connect the seams of the floor covering. Using the tool, you can quickly weld the seams of such coatings as rubber, linoleum, PVC, using only a filler cord. It should only take into account the fact that the filler cord, which looks like a long thin pencil, should have a similar chemical composition With flooring.

The process itself is carried out as follows:

Two sheets of flooring fit as closely as possible to each other
A filler cord is laid at the junction
The working temperature of the building hair dryer in this case should be about 300 degrees. We direct the thermal gun at the tourniquet, which literally melts in a couple of minutes and tightly grabs the floor covering after cooling
It remains only to remove the excess bundle with the same spatula, carefully walking along the entire length of the joint.

The craftsman who bought a building dryer now gets the ability to weld plastic pipes. It is best to use a special nozzle-reflector that comes with a hair dryer. The nozzle got its name due to the fact that it does not allow the welding object to stick to the nozzle. So, we warm up the hair dryer to a temperature of 300 degrees, after which we bring it close to both sides of the plastic pipe. Some time after blowing, the plastic begins to soften, it is at this moment that it is necessary to remove the hair dryer and attach both pipes to each other. By firmly pressing the plastic pipes for a minute, you will get a strong and reliable connection.

Finally, we will tell you how to weld film coatings. To achieve maximum effect, the film is overlapped, covering approximately 3 cm of the other film. The hair dryer is set to a temperature of 200 to 400 degrees with minimal airflow. After a few seconds, you can pick up the roller and carefully roll the newly treated area. This is more than enough to make a strong and strong connecting seam with your own hands, which will be quite difficult to break.
