Asbestos

详情

Name:asbestos;

Summary:silicate mineral products with high tensile strength, high flexibility, chemical and thermal erosion, electrical insulation, and spinnability;

Characteristics: asbestos is made up of fiber bundles, and the fiber bundles are made up of very long, very thin fibers that can be separated from each other. Asbestos has high fire resistance, electrical insulation and thermal insulation. It is an important fire protection, insulation and thermal insulation material, and insulation, heat insulation, sound insulation, high temperature resistance, acid and alkali resistance, corrosion resistance and wear resistance;

Category: natural fibrous silicate minerals;

Properties: dark green, light green, a yellow, brown, gray, white, translucent, the appearance of a fibrous, with silk like luster; fiber length is 3~50 mm;

Classification:

Classified according to the mineral composition and chemical composition: serpentine asbestos, amphibole asbestos; serpentine asbestos, or chrysotile asbestos;The main ingredients are silica, Magnesium Oxide and crystalline water;Molecular formula Mg6[(OH)4Si2O5]2; MgO 43.0% SiO2 44.1% H2O 12.9%; Hardness:2.0~2.5; Density:2.49~2.53; Axial tensile strength:3000Mpa;No magnetic, non conductive, refractory, alkali resistant, fibrous tenacious and soft, silk luster and good spinnability;The world's asbestos are mainly serpentine asbestos, accounting for about 95% of the world's asbestos production;

Amphibole asbestos includes:crocidolite,amosite,anthophyllite,tremolite,actinolite;



Application:

1. Building materials: asbestos board, asbestos paper fireproof board, insulation pipe, kiln mat and other insulation, heat proof, insulation, sound insulation material; asbestos cement products; asbestos bitumen products;

2. Textile: asbestos cloth made by asbestos stone , asbestos boots, padded  gloves;

3. Industry: asbestos insulation products, asbestos rubber products, asbestos brake products, asbestos electrical materials;
