Bakelite plywood: description, application and characteristics, what it is and where it is used, the main differences from laminated

Features of bakelite plywood

First you need to familiarize yourself with the parameters and properties of this material. It is distinguished by unique characteristics and high performance.

It is obtained as a result of exposure to high temperature and prolonged pressure under pressure.

• This plywood is based on the use of birch or pine veneer. Loose components are pre-coated with a composition based on alcohol and phenol-formaldehyde. Another name for the composition is bakelite varnish.
• A distinctive feature of bakelite plywood is its increased resistance to high humidity and fungal microorganisms. The surface of the material has fire-resistant properties. The composition based on alcohol and phenol-formaldehyde protects the decorative surface from the effects of aggressive and household chemicals.

Thanks to the dense shell, the internal structure of the finishing material copes with sudden changes in temperature.

Modern technologies make it possible to achieve high decorative qualities. Numerous studies have proven the positive qualities of the building material for 12 years.

That is why this category of finishing material is in great demand among users. Construction stores offer a large selection of textures that can fit into any interior space.

Advantages and disadvantages

Bakelite plywood is used in various construction fields. Experts call it marine. This type of finishing material is considered popular because of its positive properties.

They include:

• Versatility. Plywood sheets have high performance characteristics, have thermal conductivity and moisture resistance. Some plywood models are impregnated with fire-resistant impregnation. This substance prevents the combustion of the wood-based base;
• Plywood is not subject to rotting and deformation. With prolonged negative impact of aggressive chemistry, alkalis and fuels and lubricants, the varnish coating does not change its strength;
• Safe composition. When used correctly, this type of building material is safe for the environment and human health. However, if there are chips, scratches and visible signs of deformation, it is better to refuse to use such a series. Phenol-formaldehyde resin releases toxic fumes into the air. As a result, the breakdown products of chemical components can cause serious poisoning;
• Impeccable appearance. The decorative material has an aesthetic structure that makes it stand out against the background of other finishes;
• Light weight. You can find models of different shapes and sizes on sale. When choosing, it is important to consider the thickness of the finishing material.

Plywood in this category has several disadvantages. They are as follows:

• High price. Unlike other building materials, bakelite plywood sq.m. on average costs from 2500 rubles. Products of the FBS brand have a price tag of 4,000 rubles per 1 sq.m;
• The weight of the product is much higher than that of other types of finishing raw materials. When choosing interior structures, it is important to consider that bakelite plywood puts a lot of pressure on the support posts.

When selecting a material for this category, it is important to consider its advantages and disadvantages. Construction departments offer a large selection of decorative slabs that differ from each other in cost, shape, texture and color.

Application area

Wear-resistant and reliable material is used in various fields. The use is limited only by the fact that the sheets are expensive , so in ordinary places they use more budget options that are suitable in quality.

Areas of use:

• construction;
• mechanical engineering;
• shipbuilding;
• instrument making.

For each specific case, sheets with the required properties are selected. For temporary work, inexpensive, unsanded types are chosen, and for critical work, laminated or sanded types are chosen.

During the war

The wing parts of the LaGG-3 fighter were made from bakelite plywood.
In the pre-war years, there was an urgent need for structural materials for aircraft , so it was decided to use wood-laminated plastics, including bakelite plywood. The material showed more suitable qualities compared to wood.

The production process was developed by L.I. Ryzhkov , a Soviet aviation engineer, back in 1935 , and in 1940 it was thoroughly studied by the All-Union Institute of Aviation Materials. The technology was subsequently improved.

The material was successfully used in the construction of high-speed fighters LaGG-3 and LaGG-1 the Yak and Il aircraft were made from it . Later, the initiative was taken up by the Japanese to produce kamikaze aircraft for attacks on the naval fort at Pearl Harbor.

Currently

After the end of the war, plywood became in demand in other industries. Its other name is sea, ship, ship . The hulls of boats, boats, and yachts are sheathed with moisture-resistant material.

Other applications :

• In construction work for the installation of locks, floating docks, water seals. The sheets are used to make strong, repeatedly wrapped formwork. Supporting and load-bearing structures are built from them.
• They make car vans and lay floors in transport: buses, subways, trams. In mechanical engineering, plywood is used for the manufacture of machine parts, structural spare parts, gears, friction units, bearing shells and others.

The material is used in the field of space and cryogenic technology. In electrical engineering, they make insulators, parts of transformers, rectifiers, and are used along with textolite and fiberglass. Bakelite panels are used in the metallurgical and mining industries .

Technical features of bakelite plywood

Modern models of bakelite plywood are distinguished by their technical characteristics, which have made them popular among users. This type of material is most often made in a burgundy-red shade. During the production process, the slabs are processed taking into account the requirements of GOST.

The type and brand of construction raw materials are displayed on the surface of the logo. On average, the thickness of the slab ranges from 5 to 35 mm. Density can vary from 1000 to 1200 kg per 1 cubic meter. The mass of one slab directly depends on the thickness. For example, sheets of plywood 8 mm thick weigh 26 kg, and models with a thickness of 28 mm can reach up to 90 kg.

When selecting a finishing material, it is recommended to take into account that its strength criteria depend on static bending. The maximum tensile strength of this type of plywood reaches 74 MPa.

The strength category of bakelite plywood is far superior to dense types of wood. Experts classify this type of construction raw material as low-alloy steel.

All models of bakelite plywood are impregnated with fire-resistant impregnation. As a result, it is able to withstand temperatures of over 400 degrees. Chipboard is not exposed to open combustion. With prolonged exposure to flame, the internal structure crumbles and chars.

• The decorative coating is not subject to corrosion or deformation.
• The glossy surface does not react to chemical impurities, alkalis and aggressive compounds.
• This finish can be used in conditions in which the temperature varies from - 60 to + 60 degrees.
• Subject to storage conditions, the material can maintain its performance characteristics for 20 years.

Unique material: where to use

Due to its technical production features, bakelite moisture-resistant plywood is used in the production of small ships, in the construction of aircraft and cars, and for flooring. This is an ideal option for making formwork.

Bakelite plywood Petrovich is suitable for the manufacture of billboards and information stands. Sports equipment is also made from this durable material. Thanks to the unique combination of wood properties and increased strength, plywood can be used in interior decoration. "

Interior decoration: how to use the material

In construction, bakelite plywood is used in both internal and external work. A technological feature is the need to attach the sheets to plastered surfaces and concrete structures using a special material, such as definol mastic.

To increase the service life, it can be impregnated with a special coating or impregnation. Bakelite laminated plywood is ideal for interior decoration. All joints and cracks on the walls must be pre-primed. The joints are closed with bars.

Varieties and grades of bakelite plywood

Today there are several brands of plywood made using this method. Each type has its own characteristics and has certain operating conditions.

These include:

• FBS. The protective layer of such plywood is impregnated with an alcohol composition based on formaldehyde resin. The inside of the particle board is not soaked with such liquid;
• FBS 1. Wood-based ingredients are thoroughly impregnated with an alcohol composition containing phenol-formaldehyde components. In this way, it is possible to obtain a dense texture that is not subject to deformation and rotting processes;
• FBV. This category of building materials includes products that are coated on all sides with alcohol compounds containing formaldehyde. It is not recommended to use such slabs for interior decoration. The fact is that if the protective coating is damaged, the decay products of phenol-formaldehyde will penetrate into the air.
