Huamei Gray Insulated Glass Wool Exterior Wall Glass Wool Board National Sales Wholesale Price

Glass wool Glass wool is a filamentary material made by fiberizing glass in a molten state and spraying thermosetting resin using a centrifugal blowing process. After deep processing by heat curing, it can be made into a series of products with a variety of uses. It has many advantages such as flame retardant, non-toxic, corrosion-resistant, small bulk density, low thermal conductivity, strong chemical stability, low moisture absorption rate, and good hydrophobicity. It is currently recognized as the most superior thermal insulation, heat insulation, and sound-absorbing material. , has a very wide range of uses. Boards, felts and tubes made of this material have been widely used in thermal insulation, sound absorption and noise reduction in the fields of construction, chemical industry, electronics, electricity, metallurgy, energy, transportation and other fields. Quartz sand, limestone, dolomite and other natural ores are used. As the main raw material, it is melted into glass with some soda ash, borax and other chemical raw materials. In the melted state, it is blown into floc-like thin fibers with the help of external force. The fibers are three-dimensionally crossed and entangled with each other, showing many small gaps. This gap can be regarded as a pore. Therefore, glass wool can be regarded as a porous material with good thermal insulation and sound absorption properties. Sales phone number 3 Wang Hongtao
