Asbestos is a unique building material, which has no analogues in its properties. Its heat resistance is very high - up to 500 degrees. In construction, white asbestos is most often used.
Application area
The material is used to increase the strength of cement in the production of heat-resistant and durable sheets and pipes, pebbles. Asbestos is widely used in the creation of elements to increase their wear resistance. It is actively used in brakes as an anti-friction element, as well as in the production of asphalt. The use of asbestos is popular in industry as a filter material. It is a filler in plastics, scrap and insulators.
Asbestos technical products
Asbestos products have excellent electrical insulating, heat insulating and fireproof characteristics. First of all, they are used in industry for the establishment of sealed joints and as a fire protection. Technical characteristics are so high that they are recommended for the use of the insulator in flammable rooms. It should be noted that asbestos and its derivatives have a large scope.
In the metallurgical industry, asbestos technical products are used for the production of pipe and steam pipelines. ATI are used as heat-insulating and lining material for sewing special-purpose clothes and many other products intended for industrial use.
Non-woven asbestos cloth is also used as thermal insulation. It is used mainly for insulation of hot surfaces, it can withstand temperatures reaching 400 degrees Celsius. To insulate steam and piping and other hot surfaces, flexible asbestos paper is used. It is also made on the basis of asbestos.
Asbestos fabric: application and types
In addition to non-woven fabrics, there are fabrics woven from asbestos yarn with viscose, glass fiber or cotton thread. Such fabrics are called asbotkan (asbestos fabric) (GOST 6102-94). Again, the main characteristic is thermal insulation. Overalls for workers engaged in production in high-temperature workshops and firefighters are sewn from such fabric.
Asbestos fabric (asbestos fabric) is widely used for insulation of furnaces and other heating devices. Such fabrics are very effective in extinguishing small foci of fires and substances that are not able to burn in an airless environment.
Asbestos fabric: characteristics
It looks like a fabric like a dense canvas. It is not toxic. This quality is very important when sewing workwear. The shelf life of such a canvas, without loss of all qualities, is from 5 to 10 years.
It should be noted that asbestos fabric is used not only in the tailoring of overalls, but also in the production of rubberized fabric and asbestos textolite.
There are special types of asbestos fabrics that are intended for use in aviation.
Despite the fact that asbotkany is not toxic, precautions when working with them still need to be observed. The fact is that during use they can emit asbestos-containing dust into the environment. She, in turn, having a fibrogenic effect, can accumulate in the lungs. Therefore, workshops in which work with asbotkany is in progress should be equipped with a good ventilation system, and all employees should use personal protective equipment.
Currently, asbestos fabric is produced in a huge number of various types, grades with different properties and used in various fields.
Properties of Asbestos Tissues
Fabrics made from asbestos threads have the following advantages.
Firstly, they are high strength. Secondly, durable. Thirdly, they are wear-resistant. Fourth, they have a high ability to protect against heat and fire. And fifth, they retain their properties at high temperatures.
Ecological characteristics of asbestos tissue
Asbestos fabric has good quality guarantees and meets the norms and rules established in the country.
Asbotkan fibers can easily be split into smaller ones. Asbestos dust, which enters it when inhaled, directly affects the body. It can cause various diseases, such as lung cancer or malignant tumors of the abdominal cavity and pleura. Therefore, it is very important to observe safety precautions when working with fabrics, since it is impossible to find a safer replacement for asbestos. Only this material possesses such characteristics. But its more expensive counterparts still do not reach their mechanical properties in their characteristics.
In order to reduce the risk of inhalation of asbestos dust, products made of this material can be painted or tightened with a film, and those things that are not treated with protective materials should not be placed in places with good air exchange.
