Asbestos chrysotile: features, characteristics, scope

Asbestos is a white natural mineral, or rather, a group of fine-fiber minerals. Use this stone in many industries. There are two types of asbestos: amphibole and chrysotile. More popular is chrysotile asbestos. How it differs from the amphibole analogue, we will describe further.

Material Features

The main characteristics of the material are durability and alkali resistance. And asbestos does not burn at all. This property was known in ancient Egypt. They knew about this in Europe: Charles V ordered to weave a tablecloth out of asbestos fibers and had fun, surprising the guests by throwing the product along with the rest of the food into the fire. The food burned out, but the tablecloth remained intact.

In addition, chrysotile asbestos has the following properties:

1. Elasticity.
2. High strength.
3. Heat resistance. At temperatures above +700, the fibers of the stone become brittle, and at + 1500 degrees they begin to melt.
4. Low electrical and thermal conductivity.
5. Explosion proof.
6. Fire resistance.
7. Safety: when heated, the material does not emit substances harmful to living organisms.

Asbestos also has adsorption reinforcing and spinning properties.

Types of material

Chrysotile asbestos is divided into several groups, depending on what fractional composition the substance has. The separation takes place on the control apparatus, on special screens. Each sieve has cells of different sizes:

• 12.7 mm;
• 4.8 mm;
• 1.35 mm;
• 0.4 mm.

Further, the material according to the size of the obtained fraction is divided into 7 groups. Group 6 is considered to be the most demanded. This is asbestos chrysotile grades K-6-30, K-45, K-20, K-5. It is used in the production of asbestos-cement building materials:

1. Wavy sheets. Wavy and flat sheets are available.
2. Extrusion panels for walls and roofs.
3. Partition panels for external and internal walls in buildings and structures.

Scope of application

Chrysotile asbestos is used due to its almost unique properties quite widely. With his help:

1. Thermal insulation of heating devices, furnaces is performed.
2. Walled steam boilers.
3. They produce asbestos-cement and asbestos technical products.
4. Provide thermal insulation for curved products.
5. Protect metal structures from high temperatures, etc.

Chrysotile is also used in the paper, automotive, medical and glass industries.

Asbestos chrysotile brand K-6-30: technical specifications

The material has the following properties:

1. The limit of heat resistance is 500 ° C.
2. It begins to melt at 1500 ° C.
3. The density index is 2.6 g / cm3.
4. Alkalinity is about 10.2 pH.
5. 0.8 - coefficient of friction.
6. The tensile strength index is over 3000 MPa.

Packing, transportation, storage

Chrysotile asbestos is packed in synthetic or paper bags. The weight of the bags is 50, 45 or 40 kg. Transportation is possible using all modes of transport. The only condition for this is the ability to comply with the technical conditions of loading / unloading. In addition, the load must be firmly fixed. As for railway transport, to maximize the use of wagon capacity, it is recommended to move the material by wagon shipments.

In order for a substance to retain all its substances, it must be stored in packaged form. Preferably, the premises used for this should be closed. If storage areas are open areas or suspended structures, chrysotile must be packed in synthetic bags and covered with waterproof material on top to protect it from moisture. So the material can be stored for a long time, but not more than one year from the date of its manufacture.
