How about the appearance of glass wool, mineral wool and asbestos?
Glass wool is the molten glass fibrosis, the formation of cotton like material, chemical composition of glass, is a kind of inorganic fibers. With good forming, small volume density, thermal conductivity, both thermal insulation, sound-absorbing performance, corrosion resistance, chemical stability.
A fluffy short staple fiber made from mineral material. Including rock wool and slag cotton. Melting natural rock or metallurgical slag in a cupola or a pool furnace, etc. by blowing or centrifuging.
Glass wool belongs to a kind of glass fiber, it is a kind of man-made inorganic fiber. Quartz, sand, limestone, dolomite and other natural ore as the main raw materials, with a number of soda ash, borax and other chemical raw materials into glass. In the melting state, by means of external force, the system is thrown into flocculent fibers, and the fibers and fibers are made of solid intersection. They are intertwined with each other and show a lot of small gaps. This gap can be considered as a pore. Therefore, the glass wool can be regarded as a porous material and has good thermal insulation and sound absorption performance.
