Glass wool is widely used in fields such as construction, industry, and acoustic treatment
2025-09-28
Definition and Composition: Glass wool belongs to a type of glass fiber, which is made by melting natural minerals such as quartz sand, limestone, and dolomite with chemical raw materials such as soda ash and borax, and then using blowing or centrifugal spinning processes. Its chemical composition is similar to glass, and it is an inorganic fiber.
Production process:
Flame spraying method: using high-temperature flames to split molten glass into fibers, which are soft but have low single machine output.
Centrifugal spraying method: The glass liquid is spun into fibers by a high-speed rotating centrifugal disk, which is currently the mainstream process. The fiber diameter can be controlled within 3-8 microns, and the product performance is stable.
Product form: including board, roll felt, pipe shell, etc., moisture-proof veneer or composite materials can be added according to needs.
