Product Description:

1.Structure of Centrifugal Glass Wool Description:

Centrifugal glass wool is the glass molten state law centrifugal injection process fibrosis and spraying thermosetting resin made from filamentous material, through the thermal curing deep processing, multiple applications can be made with the department of products. It has not, non-toxic, corrosion resistance, small bulk density, low thermal conductivity, strong chemical stability , low moisture absorption rate, a lot of advantages, is recognized superior performance of heat preservation, heat insulation, sound-absorbing materials, has a wide range of USES. With the material only board, felt and pipe has a large number of used in construction, chemical industry, electronics, electric power, metallurgy, energy, transportation and other fields of heat preservation and heat insulation, sound-absorbing noise, effect is significant.

Q:What properties does glass wool felt have?
Glass wool has the functions of thermal preservation, thermal insualtion, heat dissipation and sound absorption. It is divided into wool board and felt board with different functions respectively. It depends on what effect you want. 1. Compress glass tightly to ensure that displacement will not occur. 2. Sealing the gap betwen glass sheet and window frame to ensure that dust will not enter into the room through the crevice.
Q:There is an engineering air-condition air duct which uses aluminum foil glass wool for heat conservation, supervor require that it should be added a protective layer made by glass fiber cloth. according to peremptory norms,
1, this problem is mainly depending on the contract you signed with the above 2, there is no clear guideline, if the owners is rich, you can coat moisture-proof layer containing sackcloth material and two layers of 25mm thick plaster protective layers on the 70mm bulk fiber heat conservation layer outside the air duct, and coat the outer edge with two layers of aluminium paint.
Q:Now what is the latest color steel sandwich board? such as: Foam, stretches, glass wool
Foam is the mainly material, now with the increase of rock wool, the rock wool can be fireproofing and sound absorption, it may also lay glass wool in the interior of color steel plate and the function is sound absorption and thermal insulation.
Q:What is the highest temperature that the fireproof glass cotton can resist?
It is certain that A level is the highest. A level indicates that it is non-combustible. Level B indicates that it is fire retardant. Rock wool can resist 800 ℃ and glass wool can resist 450 ℃. The hest perservation effect of matetials of B level is relatively better.
Q:How about the quoted price of asphalt glass wool felt?
The sound absorption property of glass wool board is related to veneer materials, cavity and cavity's size, the thickness of glass wool board and apparent density. Test shows that sound absorption property of glass wool board is mostly related to the thickness of board.
Q:What are the construction methods of glass wool board used in external wall?
The phenomenon of moisture condensation in glass wool should be prevented.moisture condensation in glass wool, a layer of vapour barrier should be attached to the surface of the glass wool.A layer of glass wool should be fixed on the wall by insulation supporting pin prevent the glass wool from falling and thermal insulation properties from reducing.
Q:The difference between glass wool of 50mm and rock wool.
Glass wool belongs to one of the glass fiber. machine-made fiber cotton wool molten glass fibrosis cotton material belong to glass fiber. type, bulk density, low thermal conductivity, thermal insualtion, acoustic insualtion, anticorrosion, stable chemical performance. Rockwool is also called mineral wool. Use Guangde Shida rock wool and mineral raw materials to make fluffy short fine fibers. Basalt rock wool, pyroxenite, dolomite, iron ore, bauxite can be used to make matrix fiber by going through high temperature melting process and fibrosis.
Q:Choosing glass wool with proper thickness for piping insulation of Dn900 boiler room.
It depends on the temperature of pipes. Steam pipes with 300 degrees should choose the thickness of 100mm, which is based on the national standard that pipeline’ skin should keep less than or equal to 50 degrees in temperature. While hot water pipes keep 40 to 50mm in this regard.
Q:How about the sound insulation performance of glass wool felts?
Fix the glass wool in the wall with pegs, then cover it with plywood, after laying up with wooden surface, nail the wood again.
Q:what is the quota of glass wool rigid section of thermal insulation.
Now, I also encountered the same problem, lz, can you tell me what quota should be used?
