The unique properties of asbestos make it possible to use this material in many types of industry. Basically, this is the production of asbestos-cement materials that are used for construction, as well as for shipbuilding, rocket building, mechanical engineering, automotive, electrochemical, chemical, tractor and aviation industries.
Sheet asbestos is a practical material that serves as an effective thermal insulation for premises of any purpose. Sheet asbestos, the price of which is not too high, can be used not only in industry, but also for private needs. Roofs are usually covered with such sheets. In its manufacture, all the requirements of GOST for safe and reliable use are taken into account.
Sheet asbestos has a fibrous structure, which gives the products high thermal insulation properties.
The importance of using this material is primarily due to the ability to prevent the fire of building structures. This material is very resistant to high temperatures and can become a barrier to open flames.
Also this stuffwill be used for sealing connections of communications, devices, as well as equipment and thermal insulation of pipelines or high-temperature units.
It is possible to buy sheet asbestos for small works at retail, but after the purchase it is important to properly store it. In order to avoid degradation of the material's performance, it is necessary to store it in a closed, dry place, to exclude the possibility of water coming into contact with the material.
Asbestos is very easy to handle and does not require professional skills or tools to use it. At the same time, the structure of asbestos is endowed with high rates of durability, reliability and strength due to its similarity with rocks.
Asbestos cardboard has many advantages, among which the following are worth highlighting:
- temperature resistance up to 500 degrees without material ignition;
- long term use;
- high quality structure;
- does not grow moldy and does not become covered with a fungus, as it is quite resistant to biological factors.
Asbestos cardboard can be cushioning and for general purposes.
Sheet asbestos is produced in the following grades, according to the fixed GOST 2850-95:
- CAON -1. Asbestos sheets for general purposes with a temperature limit of up to 500 degrees;
- CAON-2. Serves as a sealant for equipment and devices. It also has temperature restrictions for gases - up to 500 g, organic compounds - up to 400 g, the same restriction for s alt solutions and melts,alkalis - up to 200 gr., and inorganic acids - up to 120 gr. Celsius.
- PAK - cushioning cardboard made of asbestos. Used as a soft core in combination seals. These are mainly cylinder blocks of diesel and carburetor engines.
Sheet asbestos is produced with standard dimensions of 1000x800 mm, however, the thickness of the sheet can be different: from two millimeters to a centimeter. The thickness depends on the fire resistance of the material.
