Types and uses of asbest bezi
Asbestos cloth is made of fine asbestos yarn interlaced with warp and weft. According to its material and function, it can be divided into dust-free asbestos cloth, aluminum foil asbestos cloth, dust asbestos cloth, and electrolytic asbestos cloth. Because of its excellent fireproof function, asbestos cloth is called “fireproof asbestos cloth” in Japan, which is suitable for all kinds of heat configuration and heating system for heat preservation, heat insulation materials or processing into other asbestos quality materials.
1. Dust-free asbestos cloth:
Dust-free asbestos cloth is a good heat preservation, heat insulation, fireproof and sealing material, with large tensile strength and low loss on ignition, strong quality and strong performance. Dust-free asbestos cloth is not only used to manufacture various heat-resistant, anti-corrosive, acid-resistant, alkali-resistant and other raw materials, but also can be used as chemical filter material and diaphragm material on electrolytic industrial electrolyzers and heat preservation and heat insulation of boilers, bubbles, and mechanical parts. Material, use it as a fire curtain on special occasions. To a large extent, the dust-free asbestos cloth can be interchanged with the dust cloth. In metallurgical plants, carburizing plants, chemical plants, electric power, shipbuilding and other industries, it is necessary to use asbestos cloth to make asbestos clothing, asbestos gloves, asbestos boots and other labor protection products to prevent high-temperature sparks and toxic liquids from harming people.
2. Dust asbestos cloth:
The dusty asbestos cloth can be used to make all kinds of materials such as heat resistance, corrosion resistance, acid resistance and alkali resistance. It can also be used as a chemical filter material and a barrier material on the electrolytic industrial electrolytic cell and the insulation of steam boilers, air bags, and mechanical parts. Heat insulation material, it can be used as a fire curtain in extraordinary places. The performance is basically similar to the dust-free asbestos cloth, but the dusty asbestos cloth has obvious advantages in the area of ​​use, and the weight is relatively light. Especially in the process of manufacturing the packing, the content and length of the asbestos fiber near the side are the key to the quality of the packing. The dusty asbestos cloth does not contain stone powder, and other inorganic fibers are added to it, and the cost is higher, but the quality of the packing and other quality purposes can reach the standard. Dust-free asbestos cloth and dusty asbestos cloth have their own advantages and complement each other.
3. Aluminum foil asbestos cloth:
Aluminum-foil asbestos cloth is a composite aluminum-foil asbestos cloth composed of aluminum foil paper and asbestos cloth, to better exert the appeal of fire and heat insulation. Aluminum foil asbestos cloth can be divided into: dusty aluminum foil asbestos cloth and dust-free aluminum foil asbestos cloth.
4. Electrolytic asbestos cloth:
It is mainly used for heat preservation and heat insulation of various thermal equipment, strengthening materials for rubber and plastic products and duplicating various asbestos products. Function: The nominal texture is flat, bright, strong alkali resistance, low temperature resistance, and high tensile strength.
