Q:Whether the rigid section of aluminium foil glass wool can be twined with glass fiber cloth
This is not necessary, it depends on the place the shell is used, the best thing is to add a layer of insulation tape.
Q:Centrifugal glass wool board and polyurethane foam, which has better thermal insulation performance?
In terms of the thermal insulation performance, rigid PU foam is certainly the best, which has heat conduction data.
Q:What kind of glass wool pipe is this? Where is it sold?
I do not know the specification of it.
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.
Q:Which is more effective in retarding fire, rock wool or glass wool? What is the difference between rock wool and glass wool?
In terms of fireproof effect, rock wool is certainly better than glass wool. The maximum temperature of rockwool is 1100 ℃, and glass wool is only 600 ℃. In addition if used in the external walls, the highest unit weight of glass wool can only be in the range of 60-90, but rock wool can be over 140. Generally glass wool can not be used in external wall at present. Only rock wool is A grade fireproof material.The heat conductivity coefficient of glass wool is lower than glass wool and the fibre length of rock wool is longer than glass wool. As for price, tons of glass wool rock is more expensive than that of rock wool. However, if counted by square size, glass wool is cheaper per square size than rock wool.
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:The differences between rock wool board and glass wool board
has good sound absorption properties, whose chemical composition belong to glass, has a large number of tiny pores, oil, good acoustic performance, boiler, make man-made inorganic fiber with high-speed centrifugation equipment, national defense. rock wool board has a high temperature endurance of 650 degrees, transportation and other industries, fan. Fibers inside the centrifugal glass wool are fluffy and staggered into cotton-like material, which is the ideal thermal insulation and sound insulation material with stable chemical properties. Glass wool is made by fibrillating the melten glass and then heating and curing into a variety of specifications, metallurgy, flue, textiles, automotives and boats and other industrial equipment, with features of insulation resistance and corrosion resistance, which is an inorganic fiber, with good shape and low thermal conductivity. Glass wool is one of the glass fiber categories with small bulk density, rock wool insulation products and heat exchangers of different requirements, is a kind of man-made inorganic fiber, is pipeline basin. Rockwool products are widely used, while adding special binder and dust laying oil, electricity, suitable for construction. glass wool has a high temperature endurance of 450 degrees, the main raw material of rock wool is natural basalt, which is typical porous sound-absorbing material after being melted in high temperature.
Q:What is the difference between rock wool and glass wool?
Q:Is centrifugal glass wool or rubber and plastic insualtion board better for air-conditioning air duct insualtion?
Rubber and plastic insulation board is better.
Q:During the construction of steel structure, should the aluminum foil of glass wool be directed indoors or outdoors? Why?
When the steel structure is constructed, aluminum foil of glass wool should point toward the indoor.
