Types and types of plastic, classification of plastic. What kind of material is used in the production of plastic containers. Plastic. The most durable materials in the world AND durable plastic used in

Durable materials have a wide range of uses. There is not only the hardest metal, but also the hardest and strongest wood, as well as the strongest man-made materials.

Where are the most durable materials used?

In excess of durable materials used in many areas of life. So, chemists in Ireland and America have developed a technology by which durable textile fibers are produced. The thread of this material is fifty micrometers in diameter. It is created from tens of millions of nanotubes, which are bonded together with the help of a polymer.

The tensile strength of this electrically conductive fiber is three times higher than the strength of the web of the orb-weaving spider. The resulting material is used to make ultra-light body armor and sports equipment. The name of another durable material is ONNEX, created by order of the US Department of Defense. In addition to its use in the production of bulletproof vests, new material can also be used in flight control systems, sensors, engines.

There is a technology developed by scientists, thanks to which durable, hard, transparent and light materials are obtained by converting aerogels. On their basis, it is possible to produce lightweight body armor, armor for tanks and durable building materials.

Novosibirsk scientists have invented a plasma reactor of a new principle, thanks to which it is possible to produce nanotubulene - heavy-duty artificial material. This material was discovered twenty years ago. It is a mass of elastic consistency. It consists of plexuses that cannot be seen with the naked eye. The thickness of the walls of these plexuses is one atom.

The fact that the atoms are sort of nested into each other according to the “Russian nesting doll” principle makes nanotubule the most durable material known. When this material is added to concrete, metal, plastic, their strength and electrical conductivity are significantly enhanced. Nanotubulene will help make cars and planes more durable. If the new material comes into wide production, then roads, houses, and equipment can become very durable. It will be very difficult to destroy them. Nanotubulene has not yet been introduced into widespread production due to the very high cost. However, Novosibirsk scientists managed to significantly reduce the cost of this material. Now nanotubulene can be produced not in kilograms, but in tons.

The hardest metal

Among all known metals, chromium is the hardest, but its hardness depends largely on its purity. Its properties are corrosion resistance, heat resistance and refractoriness. Chrome is a whitish-blue metal. Its Brinell hardness is 70-90 kgf/cm2. The melting point of the solid metal- one thousand nine hundred and seven degrees Celsius at a density of seven thousand two hundred kg / m3. This metal is in earth's crust at a rate of 0.02 percent, which is a lot. It is usually found as chromium ironstone. Chromium is mined from silicate rocks.

This metal is used in industry, smelting chromium steel, nichrome and so on. It is used for anti-corrosion and decorative coatings. Chromium is very rich in stone meteorites falling to Earth.

The most durable tree

There is wood that is stronger than cast iron and can be compared with the strength of iron. We are talking about "Schmidt's Birch". It is also called the Iron Birch. Man knows no more durable wood than this. It was opened by a Russian botanist named Schmidt, while in the Far East.

Wood exceeds the strength of cast iron by one and a half times, the bending strength is approximately equal to the strength of iron. Due to such properties, iron birch could well sometimes replace metal, because this wood is not subject to corrosion and decay. The ship's hull, made of Iron birch, can not even be painted, the ship will not be destroyed by corrosion, the action of acids is also not afraid of it.

Schmidt's birch cannot be pierced by a bullet, you cannot cut it down with an ax. Of all the birches on our planet, it is the Iron Birch that is long-lived - it lives for four hundred years. Its place of growth is the Kedrovaya Pad Nature Reserve. This is a rare protected species, which is listed in the Red Book. If not for such a rarity, the heavy-duty wood of this tree could be used everywhere.

But the tallest trees in the world, sequoias, are not very durable material.

The strongest material in the universe

The most durable and at the same time lightweight material our universe is graphene. This is a carbon plate, which is only one atom thick, but it is stronger than diamond, and the electrical conductivity is a hundred times higher than the silicon of computer chips.

Soon graphene will leave scientific laboratories. All the scientists of the world talk today about its unique properties. So, a few grams of material will be enough to cover an entire football field. Graphene is very flexible, it can be folded, bent, rolled up.

Possible areas of its use - solar panels, Cell Phones, touch screens, super-fast computer chips.

Like wurtzite boron nitride, lonsdaleite is a natural substance that is harder than diamond. Moreover, this amazing mineral is harder than diamond by as much as 58%! Like wurtzite boron nitride, this compound is extremely rare. Sometimes lonsdaleite is formed during a collision with the Earth of meteorites, which include graphite.

Our company is engaged in the supply of semi-finished products of engineering plastics in the form of sheets, rods, plates, bushings, pipes, as well as the manufacture of industrial capacitive equipment, chemical-resistant air ducts, galvanic baths, pools, fonts, cages and linings for different kind tasks.

In addition, with the help of CNC, molding and injection molding, we will produce both piece and serial production of plastic products of any complexity!

This article is intended to acquaint our visitors with the capabilities of the company and talk about our capabilities, services, as well as help in choosing the material for your task.

So, what are polymers and in what cases they are used.

If you need to choose a plastic for any task, you need to determine the most important performance characteristics:

• temperature - constant operating, minimum and maximum
• plastic environment
• mechanical influences on it.
• environmental requirements

Having outlined the requirements for operating conditions, one more important parameter can be determined - price on plastic! The price of materials can differ by tens or even hundreds of times, since operating conditions affect not only the type of plastic, but also the choice thickness. The thickness, in turn, affects the amount of material that will need to be purchased, since the cost of sheets, rods and plates is measured based on weight per kilogram.

Depending on the upper limit operating temperature It is possible to carry out a conditional division of plastics into several groups:

• Industrial (standard) plastics - up to 100°С
• Engineering (structural) plastics - from 100°С to 130°С
• Plastics high level, high temperature - from 130°С to 300°С

The higher the operating temperature of the material, the more perfect the molecular structure of the material and the stronger the intermolecular bonds, the higher its cost will be and at the same time its consumption volume will decrease. For example, the volume of consumption of polyvinyl chloride (PVC, PVC) is three to four orders of magnitude greater than the volume of consumption of polyetheretherketone (PEEK), the unit cost of which is two orders of magnitude greater than that of PVC.

Work environment influences choice chemical resistance material. AT chemical production components are used that require both proper storage in tanks or containers, directly involved in technological process and proper disposal.

And depending on the operating criteria mentioned above, thermoplastics are used to create capacitive equipment - PP (polypropylene), PE (polyethylene), PVC (polyvinyl chloride or vinyl plastic), PVDF (polyvinylidene fluoride). Each of these polymers has its own advantages and application possibilities, and also has the ability to fully replace capacitive equipment made of metal or of stainless steel, they are simply indispensable in the production of modern electroplating equipment and chemical-resistant air duct systems. Replacing metal containers with plastic ones allows you to increase the shelf life of the equipment, reduce its cost and weight, and in most cases it is the only possible solution.

Speaking of impact environment on plastic it is impossible not to mention this important parameter, how radiation resistance. Operation on nuclear power plants, x-ray equipment, medical equipment, satellites, military equipment and technology special purpose- this and many other equipment requires resistance to X-ray and Gamma radiation from plastic. And here materials such as PVDF (PVDF, polyvinylidene fluoride), PEEK (polyetheretherketone), PEI (polyetheramide), PAI (Torlon, Polyamide-imide), PI (Polyimide) are widely used.

Mechanical effects consist of several characteristics:

Strength matters at static voltages, i.e. under constant tensile load (for example, in capacitive equipment). Plastics with high tensile and tear strength tend to have poor elasticity and vice versa. This makes it possible to divide plastics into “strong” (hard) ones that can withstand high mechanical loads, but quickly break when deformations occur; and elastic (flexible), which are not so strong, but are able to maintain their strength properties during deformation.

impact resistance characterizes the resistance of materials to dynamic loads.

Hardness and wear resistance mean the resistance of the material to punctures, cuts, etc., resistance to abrasion, which is important, in particular, for the lining of process equipment.

In some cases, strong and hard plastics are chosen that can withstand loads of tens of tons, such as PA (polyamide), POM (polyoxymethylene), PET (polyethylene terephthalate).

In other cases - flexible and at the same time impact resistant, such as polyethylene (PE) and polypropylene (PP) .

Consider some of the most popular properties of plastics on the market.

Heat resistance, as mentioned above, depends on the operating temperature of the material. The most heat-resistant plastics from the category of high-temperature ones, they, due to their high technology, have the highest cost. The most popular plastics from this category are polyetheretherketone (PEEK, PEEK), polytetrafluoroethylene (PTFE, PTFE), fluoroplastic (f4), polyvinylidene fluoride (PVDF, PVDF).

Frost resistance for plastics it is characterized by brittleness temperature. The brittleness temperature is the temperature at which the destruction of a material or product occurs under conditions of a constantly acting load. For plastics, it is in the negative zone and for each of them it has its own value, which is below the minimum operating temperature. For example, for polyethylene low pressure high density PE 300 is lower than -50°C; high molecular weight polyethylene PE 500 - -100° C; ultra-high molecular weight polyethylene PE 1000, lower than - 250 ° C. At the same time, brittleness of polypropylene homopolymer PP-H appears even at temperatures below 0 ° C

When choosing sheet plastic, the question arises as the choice thickness sheet.
The most popular plastics on the market are available in the following thicknesses:

The concept of the strength of plastic from the point of view of the layman and the engineer is very different. If we are talking about everyday strength, then we mean a simple understanding on the basis of "breaks - does not break." The same characteristic for production, construction, design has many aspects, the study of which reveals that all materials have a number of features by which one can determine their purpose and the possibility of using them for certain purposes.

Unfortunately, it will not be possible to point to the most durable polymer for objective reasons. This is explained by the fact that physical and strength characteristics are classified according to a wide range of features, the totality of which determines the concept of strength. It depends on the properties of the plastic itself, its structure and response to change. external conditions. For example, it is considered "strong" for creating concrete monoliths, but exhibits extremely poor resistance to bending, breaks. Similar contradictions for a non-specialist can be found in the properties of any polymer and the material based on it - plastics.

Characteristics of strength, hardness, elasticity of plastic

In the concept of strength (the nature of the reaction to physical exercise) it is customary to include the results of testing the material according to several criteria. Depending on what force was applied to the sample, it is possible to find out the characteristics of the polymer, its ability to resist a certain profile load:

compressive strength - preservation of the physical structure and shape of the sample during compression;

tensile strength characterizes the ability of the sample to resist tensile force;

deformation strength - a criterion indicating the ability to resist deformation and return to its original position;

plasticity limit - the minimum force at which the material "flows", stretches without returning to its original shape;

impact strength - the ability to absorb impact energy without destroying the structure;

hardness - the reciprocal of plasticity, the limit of shape retention under force.

Depending on what kind of loads will be perceived by the product in the process of production, processing and operation, a material with certain properties is selected. Therefore, it is useless to talk about the most durable polymer. ? - this is a question that requires a comprehensive answer, consideration of the totality of signs.

Strength of different types of plastics

Practical examples of strength characteristics evaluation different plastics and plastics show how intricately their properties intersect when viewed professionally.

Deformation strength

Polystyrene, polycarbonate, polymethyl methacrylate are characterized as mechanically strong materials under various stresses, but the deformation load quickly causes their destruction. With a significant impact, the strength will be low, but a significant deforming force will be required to destroy a hard plastic. So, the hardness of plastic speaks of its strength, limited impact strength and brittleness during deformation. It's easy for a non-specialist to get confused.

Flexibility and plasticity

Polyethylene and polypropylene belong to the group of plastic materials - they slightly resist deformation, but at the same time for a long time do not break under such a load. This ability is characterized by the initial modulus of elasticity - the initial resistance to the deforming force is quite large, but after overcoming a certain limit, deformation begins. Flexible plastics can be characterized as less durable, but with high impact strength. They well absorb energy from the outside, upon impact and load, change shape for a long time, do not "break". That is why it is used where high flexibility of the material is needed, the ability to withstand significant force while maintaining its shape.

Durable fiber plastics

Materials such as Kevlar, nylon and carbon fiber have high strength, comparable to hard plastics, they perceive shock loads to a limited extent, are able to resist deformation for a long time. Their main advantage is the ability to resist tensile strength for a long time. That is why fibers are used where there is a high probability of tensile stress. An example of this is Kevlar, which can not break under the forces that tear steel.

Plastic, or plastic, is an organic material based on macromolecular compounds - polymers. The opinion that plastic is more durable and quality material than plastic is erroneous. The difference between these concepts is only in their name. Types of plastic, its types, classification, labeling, areas of use are huge.

What it is

Plastic products have firmly entered our lives. Particularly widely used are plastics based. The manufacturing process is the transition of a material under the influence of heat and pressure from a fluid state to a solid state. The development of plastics began with the use of natural ingredients. Later they were replaced with chemically modified materials. Now, for the manufacture of plastics, fully synthetic molecules are used - polyethylene, polyvinyl chloride, epoxy. And the secret of popularity is as follows: ease of production, practicality, affordable price.

Main characteristics

The types and properties of plastic, its weldability primarily depend on the polymer from which it is made. All kinds of additives, additives, stabilizers, pigments, organic and inorganic fibers also affect the physical and mechanical characteristics of plastics. Some, for example, protect plastic from ultraviolet radiation.

The material is mostly white or transparent. With the addition of dyes, plastic can acquire any color. In this way, a mirror plastic can be produced. Most plastics are multi-component and composite materials. Plastic has a low density. Resistant to acids and alkalis. It has low thermal and electrical conductivity. Most species are easy to process. This allows the production of molded products from raw materials, as well as the use of sheet plastic, combining thermoforming with mechanical processing.

Areas of use for plastics

The scope of plastics is huge. Starting with use in shipbuilding, aircraft building, ending with agriculture, medicine and everyday life. The types of plastic are amazing. Photos show only a small fraction of the products:

• Plastics are widely used in the manufacture of parts for large vehicles, as well as for interior decoration salons.
• Development Agriculture involves the use of plastic in land reclamation, manufacturing packaging materials for the storage of agricultural products, the construction of film shelters and greenhouses.
• Lots of medical instruments special dishes, drug packaging are made from
• In construction, these are metal-plastic pipes and fittings. An alternative to glass is designs made of light or transparent plastics.
• In everyday life - the use of all kinds of containers, bottles, packages, children's toys and much more.

transparent plastic

Plastic types include thermoplastic PVC, which is mainly used for sheet materials. It is used in construction, outdoor advertising and other fields. Variety sheet material is transparent plastic. Depending on the light transmission capacity, the material can either block or transmit some of the ultraviolet rays. It can be transparent and translucent colored sheet materials.

Types of transparent plastic are represented by plexiglass, polycarbonate, polystyrene, polyester glass, transparent PVC sheets. First of all, they are impact resistant. More durable is polycarbonate. Polyester glass is considered the most elastic. The light transmission capacity is higher for plexiglass, it is the most transparent and clear, it is well processed. Transparent plastic is used for glazing windows, goggles and police shields, making plastic bottles. Transparent plastic can have different shades.

Plastic facades

Types of plastic for facades are divided into sheet and roll. Hard and solid sheet of material is plastic high pressure. Cold or medium pressure roll plastic is of lower quality and cheaper than sheet plastic. This material in rolls resembles It is used, among other things, in the manufacture of furniture facades.

Types of plastic for the kitchen have a different basis. Some are made on the basis of chipboard, and it is cheaper than the base of MDF. sheet plastic thermally stable, it is not subject to scratches, chips, impacts, does not deform, does not tarnish or fade. The material does not peel off from the base, is not afraid of moisture, and is easy to clean. The disadvantage of facade details is that they can only be even, without milling, and smooth in texture.

Finishing

And today, plastic remains popular. building material. Mainly used different types plastic for finishing offices. But in the presence of imagination and with a competent design, such material will look great in the decoration of the apartment. Plastic can be sheathed on any surface, whether it be a ceiling or walls. The main type of material for ceiling surfaces- it varies widely. Separate elements are interconnected with the help of stiffening ribs (the panel has a groove on one side, and a spike on the other). The material is light and safe. Convenient for transportation and easy to assemble.

Plastic, having moisture resistance, is used in bathrooms and when facing balconies. It is used for arranging slopes and finishing ceilings. With a successful and competent choice of plastic, you get an excellent entrance hall. Plastic panels can be matte or glossy, imitate wood or stone.

Advantages and disadvantages

In some areas of human activity, many types of plastic are approved for use by the Ministry of Health:

• Weather resistant material. It has good electrical insulation and
• Easy to process. Easy to weld and glue. You can cut and form the necessary structures.
• The material is inexpensive. long time retains its original view. Not afraid of moisture.
• Has a rich color range. Sheet transparent plastic possesses shock-resistant and fire-resistant properties. From it you can get products of various shapes.
• resistant to temperature changes. When finishing the room, it plays the role of a sound and heat insulator. Suitable for arranging awnings, street signs, signs, advertising objects.

Like any material, plastic has some disadvantages:

• Resistant to many organic solvents.
• Plastic elements can be deformed under heavy loads or high temperatures.
