The inner fiber of the centrifugal glass wool is fluffy and interlaced, and there are a lot of tiny pores. It is a typical porous sound absorbing material and has good sound absorption characteristics. Centrifugal glass wool can be made into wallboard, ceiling, space sound absorber, etc. It can absorb the sound energy in the room in a large amount, reduce the reverberation time and reduce the indoor noise.
Centrifugal glass wool belongs to a category of glass fibers. It is an artificial inorganic fiber. Natural ore such as quartz sand, limestone and dolomite is used as the main Raw Material. With some soda ash, borax and other chemical raw materials melted into glass. In the melted state, by means of external force, the blown type is formed into flocculent fine fibers, and the fibers and the fibers are three-dimensionally intersected. They are intertwined with each other and present many small gaps. This gap can be seen as a void. Therefore, the centrifugal glass wool can be regarded as a porous material, and has good heat insulation and sound absorption performance.
The main production process of glass wool by centrifugal twisting method is to melt the mixture of various raw materials into a glass liquid in a certain proportion, and the glass liquid forms a stable liquid flow through the front furnace platinum drain plate, and then flows through The spinning machine reaches a high speed rotating centrifuge with small holes in the side walls. Under the action of centrifugal force, the glass liquid is twisted into primary fibers. Thereafter, under the action of the mixed gas sprayed at a high speed, the primary fiber is pulled into a glass fiber, and the glass fiber is sprayed with the binder while dropping the cotton mesh belt, and then compacted, solidified, cross-cut, and slit. Form a certain specification of the product.

Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, Additives, plasticizers and other intermediates. Because it was originally used to make dyes, also known as dye intermediates.now it is referred to the various intermediates obtained during organic synthesis.
