Q:Is centrifugal glass wool board suitable for home use?
A large number of people think that glass wool boards are harmful and that it will cause itch when contacting with the skin. And the effect is not obvious used in the surface, so it is generally used in the wall sandwich. They are harmless for wool boards have been checked, and only those which have passed the national inspection are allowed to be sold for home use. But do not use it in the surface as it is fiber products.
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:Glass wool and pef air conditioning insulation material, which one is better?
PEF is relatively good, compared to glass wool, glass wool is not recommended to use, which has poor waterproof effect, and try to use rubber instead! Select the appropriate thickness according the local winter temperature, or it will be frozen if it is too thin in winter.
Q:What are the standards of glass wool board?
The thickness of glass wool board are 0.7 mm and 0.5m m, and it will soon enter the thinner (eg 0.4mm) thickness process. Basically, a TFT- LCD panel needs two glass substrates, they are used for bottom glass substrate and the base plate of color filter. Generally, the supply proportion of liquid crystal plate assembling factory and processing factory of the color filter glass substrate by glass substrate manufacturing suppliers is about 1:1.1 to 1:1.3.
Q:Why does glass wool turn black when exposed to heat? Wether it will ffect the thermal insulation effect.
The burning like alcohol lamp uses glass wool as the substrate. There are two possibilities to take alcohol lamp to do experiment, which containing organic substances. 2. 1, High temperature oxidation. I produce aerogel thermal insulation felt, and I have seen that the charcoal ash produced is attached to the glass wool. It has some impact on thermal insulation effect, but the impact is small.
Q:How to convert thickness if the heat insulation effects of glass wool board and rubber and plastic board is the same?
Calculated in accordance with the respective heat insulation layers
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:What is the uses of aluminum foil glass wool felt?
Roll glass wool felt is coiled materials for large area coverage. It is not only thermal-insulating, but also can reduce shock and absorb sound,especially the medium and low frequency noise. It can help reduce the noise and improve the working environment. This material can be tailored based on the actual needs, mainly used for architectural indoor, muffler systems, transportation, refrigeration equipment, damping, sound absorption, noise reduction for the household appliances. Glass wool felt overlaid with aluminum foil has strong thermal radiation resistance. It is good lining material for high temperature workshops, control room, inner walls of machine room,compartment and flat top.
Q:what's the differences between glass wool roll mat and rock wool roll mat? does glass wool roll mat have any mandatory retest requirements or environmental requirements?
Steel structure roof basically uses glass wool roll mat, because rock wool roll mat is six to ten times heavier than glass wool roll mat, light steel frame can't bear so much gravity, glass wool is more fluffy than rock wool, so it's thermal insulation effect is better, glass wool is cheaper than rock wool, the glass wool fire rating is A-level flame retardant, now people won't use the rock wool blanket, wall thermal insulation used rock wool board.
Q:What are the differences between the glass fiber and glass wool? ?
Glass fiber is a kind of inorganic non-metallic material,which is widely used in the chemical, electronics, communications, etc.; Glass wool is one of the glass fibers, which has narrower applications.
