Application

Glass Wool are widely used in public, commercial and residential buildings as well as industrial plants, for applications such as roofing, external wall, partition wall and floating floor to provide fire protection, thermal insulation, acoustic control and condensation control.

Q: Is hyperfine glass fiber cotton different from the centrifugal glass wool?: They are basically the same.

Q: What is the density of high-temperature glass fiber: glass wool density is generally between 16K ~ 32K, mainly used for acoustic and thermal insulation, but easily casues layering. Harmful substances comes out at the first heating. it is cheap. The density of the glass fiber acupuncture felt is 110~180kg/m3. It is mainly used for environmental protection, sound-absorbing. it has better fireproof property but it is more expensive.

Q: What are the differences between glass wool and natural cotton? Are there any differences when touching?: The glass wool has no peculiar smell. The natural cotton refers to cotton with no use of pesticides and chemical mordants from plantation to processing. It has advantages of aging resistance and sound absorption (effective sound insulation), etc. So it belongs to glass in terms of chemical composition. The ashes of natural cotton being burned are gray, almost black dust. The main feature of it is good perspiration absorption, then burn it: cut a small piece of cotton, it is comfortable, so I can not tell you about it. Distinguish method, it is the most suitable material for human skin for its green and environmental protection process. It can directly touches human skin, has no pilling. And it is antistatic and antipruritic with no use of pesticides and chemical mordants. Glass wool is fireproof: as for the hand feeling, I do not know any differences between them. Glass wool fiberizes the melten glass. Since the glass wool is fireproof and moisture-proof, forgive me. Cotton with no industrial sewage discharges during production has no ashes. (Ps, to form a cotton-like material

Q: Does rock wool refer to the glass wool?: Rock wool is not glass wool, ~ ~ ~ two kinds of products, appearance, price, performance are different, have obvious difference.

Q: What are the advantages and disadvantages of centrifugal glass wool?: Centrifugal glass wool is a kind of filiform material made by fibrillating and spraying thermosetting resin on the glass in melten state via centrifugal blowing process, which is then conducted thermosetting deep processing to make series products of a variety of uses. The fiber inside centrifugal glass wool is fluffy and staggered, with a lot of tiny pores, which is typical porous sound-absorbing material and has good sound absorption properties. Centrifugal glass wool can be made into wallboard, ceiling, space absorber, etc., which can absorb a lot of sound energy within the room, reducing the reverberation time and indoor noise. Glass wool carpets and sound-absorbing cotton blankets are an ideal kind of sound-absorbing and thermal insulation material, which are widely used in house walls, ship engine room insulation; the computer room, the refrigerated storage constant temperature; noise reduction of various generator rooms and pump rooms; adjustment of stereo cabinet and audio.

Q: How to conduct thermal insulation construction of external wall glass wool?: Construction recommendations: Installing metal frameworks in the floor and in their corresponding roof, trying to ensure that the framework should be perpendicular to the floor; erecting metal framework in the location apart 60cm from the metal frameworks that have been placed; pasting gypsum board on one side of the frameworks and fix it to the frameworks; putting glass wool in the gap of frameworks; pasting gypsum board on the other side of the frameworks.

Q: What environmental pollutions will be created during the production of glass wool?: There are harmful health hazards in the exhaust gas during the production of glass wool, such as phenol, formaldehyde, and glass fiber dust. Glass wool is very small. If it is on the skin, it will be atingle and itchy. If it gets into lungs, it will be quite dangerous.

Q: What are the differences between glass wool and rock wool in terms of thermal insulation?: If the temperature is higher than 300 degrees, the rock wool boards are better. The operation life of glass wool at high temperature is short, and the price of which is higher than that of rock wool. Galvanized board can be used as protective layer for its long operation life but it rusts easily and is not so beautiful. The aluminium plate has a short operation life and it damages and deforms easily.

Q: How is the prospects for rock wool board and glass wool board?: It is good.Some countries control the use of extruded polystyrene board.Moreover, no new and better energy-saving materials emerge.Therefore, these two materials will be more widely used.

Q: What industry does the glass wool belong?: Glass wool belongs to building materials,is mainly used in steel structure and color steel movable house.
