FAQ

No,glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. Taking quartz sand, limestone, dolomite and other FIR stone as main raw materials, and is melted into glass after mixed with some pure alkali, sodium borate and other chemical raw materials. In melting state, transfer them into flocculent fibers under the effect of external force, fiber and fiber are in three-dimensional crossing and winded with each other, presenting many little gaps. The gaps can be regarded as air voids. Therefore, glass wool can be regarded as porous materials, it has good heat insulation and sound absorption performance.

nan

Rock wool and glass wool belong to Class A fireproofing rating, secondly, rock wool can endure high temperature of 800 degrees, glass wool high temperature of 450 degrees, again,unit weight of rock wool is relatively heavier and unit weight of glass wool is lighter, finally, glass wool has better waterproof performance.

Price informatin form July to August, 2010 in Yuncheng, Shangxi: Rock wool tube is 330 yuan / m3 , while centrifugal glass wool tube is 680 yuan / m3.

The issue of density and thickness, the main reason should be that the density is too low

nan

Low density than glass wool rock wool, low shot content, low thermal conductivity, long service life, high tenacity fiber, rock wool, but the maximum use of high temperature up to about 600 degrees Celsius, the glass wool is only about 260 degrees Celsius. Glass wool and rock wool insulation board insulation board product differ in their application . The former one is used in areas where the temperature is below 200 degrees Celsius, such as general buildings and low-temperature pipes while the latter one is used in areas where the temperature is 500 degree Celsius, such as high temperature thermal pipe or eletrical equipments insualtion.

Fiberglass is an excellent inorganic non-metallic material. There are many kinds of glass fibers whose advantages are good insulation, heat resistance, corrosion resistance, high mechanical strength, and the drawbacks are brittle and poor wear resistance. Glass wool, a man-made inorganic fiber, belongs to a kind of glass fiber. It is a spongiform material made through fibration of melten glass. It is an inorganic fiber whose chemical components belong to glass, having good formability, low bulk density, low thermal conductivity, good thermal insulation and sound absorption, corrosion resistance and chemical stability.

The direct relationship between sound level and the density of glass wool. It has sound absorption penetrability, also can be wall.

the manmade inorganic fiber is made by the high-speed centrifugation equipment. it molding is good. the different rock wool thermal insulation products has different requirements, and it can be made into different specification and the material of the cotton-shaped is the inorganic substance fiber with stable chemical performance. Glass wool is melten glass fibrosis, it is corrosion resistance, and man-made inorganic fiber, while adding a special binder and dust?laying?oil, low bulk density, good sound absorption, thermal insulation, low thermal conductivity. Glass wool belongs to a category in glass fiber, chemical composition belongs to glass, melting in high temperature! the specific defination is in the following rock wool is taken the natural basalt as the main raw material. the two names are different but the thermal insulating and refractory material performance is nearly the same.
