The Song Dynasty fiber silicate board has good alkali resistance and is almost not corroded by alkali, but its acid resistance is poor. A very weak organic acid can precipitate the magnesium oxide in the fiber silicate board, making the fiber silicate board The strength of the board decreases. Amphibole fiber silicate plates have a monoclinic crystal structure. The color is generally darker, the specific gravity is larger, it has higher acid resistance, alkali resistance, chemical stability, and better corrosion resistance. In particular, blue asbestos has good filtration performance and has important properties such as preventing chemical poisons and purifying air contaminated by radioactive substances. The difference between fiber silicate board and amphibole asbestos is to grind the fiber silicate board in a mortar. Serpentine fiber silicate board forms a messy felt ball, and the fibers are not easy to separate. Amphibole fiber silicate board After grinding, it easily breaks into many fine fibers. Asbestos without iron appears white, and fiber silicate boards containing iron appear in different shades of blue. The fibrous aggregate has a silky luster, and the split fiber has a dull luster. The fiber silicate plate is an aggregate of fine tubular fibers arranged parallel to each other. It can be split into very fine fiber silicate plates, and the diameter can be as small as .micron or less. . After complete splitting and loosening, it is difficult to observe with the naked eye, so it is a good bacterial filtration material. Asbestos with a dimension length of more than 1 mm and ~% cotton yarn can be mixed with ~% cotton yarn to make fire-resistant textile materials. Shorter fibers can be used to make asbestos glue cloth, asbestos boards and insulation materials, etc. Blue asbestos has unique properties of preventing chemical poisons and purifying the air polluted by radioactive particles. It is used to make various high-efficiency filters. The filtration efficiency of asbestos paper made from it reaches .%.
Fiber silicate boards with vertical cracks are called transverse fibers. The length is generally less than centimeters. Serpentine fiber silicate boards are mostly produced in this form. Fiber silicate boards extending in the direction of parallel cracks are called transverse fibers. Longitudinal fibers can reach more than 1 meter in length, and blue asbestos is mostly longitudinal fibers. Other asbestos have both fibers. Fiber silicate board is a sound-absorbing material specially designed for areas with high sound absorption requirements such as elevator shafts and machine rooms. Due to its unique wave structure, it increases the effective sound-absorbing area and changes the reflection of sound. The effect is to improve the sound absorption coefficient. It is made of centrifugal fiber silicate board and sound-absorbing particles. The centrifugal fiber silicate board itself is a filamentary material made by fiberizing molten glass using centrifugal blowing process and spraying solid resin. It has the advantages of non-combustible, non-toxic, corrosion-resistant, low bulk density, low thermal conductivity, low temperature absorption rate, and good durability. It is a thermal insulation, heat insulation, and sound-absorbing material with superior performance. At the same time, the sound-absorbing particles composited on the surface of the corrugated fiber silicate board are porous sound-absorbing materials with good sound absorption effects. Therefore, the combination of the two materials significantly improves the sound absorption coefficient and achieves sound absorption in some specific areas. Noise reduction requirements.
