Q:What's the necessary performance tests lass wool used for steel structure need to do?
Flame retardant and thermal insulation performance
Q:What are the disadvantages of glass wool? What are the technical limitations in application?
Glass wool is one kind of the glass fiber and it is a man-made inorganic fiber. Glass is made by melting such raw materials as quartz sand, limestone, dolomite and other natural ore with some chemical materials like pure alkali and sodium borate. In the molten state, the glass is thrown into fine fibers in the shape of floc by the with external force. These fibres vertically interwine and show many small gaps. These gaps can be regarded as air void. Thus, glass wool can be regarded as porous materials and it is of good insulation and sound absorption performance.
Q:What are the differences among glass wool, rock wool and mineral wool?
Glass wool: The main raw material is glass, the fire rating of which is A-level, and the heat conductivity coefficient is 0.037, the shrinkage temperature is around 270 degrees. Uses: It has a significant cold insulation performance. Rock wool: The main raw material is basalt, the fire rating of which is A-level, and the heat conductivity coefficient is 0.040, the shrinkage temperature is around 730 degrees. Uses: It can be used in high-end engineering projects such as construction, shipbuilding, petrochemical ones. Mineral wool: The main raw material is slag, the fire rating of which is A-level, and the heat conductivity coefficient is 0.044, the shrinkage temperature is around 680 degrees. Uses: It can be used as filling and thermal insulation materials for curtain walls.
Q:To reach better sound absorption effect, which should be filled in the keel, glass wool felt / board or polyester fiber cotton felt / board ?
Glass wool board Glass wool board is mainly used for sound insulation. Glass wool felt is mainly used for thermal insulation, and polyester fiber cotton felt is mainly for thermal insulation and sound absorption.
Q:What are the differences between glass wool felts and rock wool board in terms of appearance, and how to distinguish them?
First, the color. environmental glass wool is while, while rock wool is dark.
Q:What are the advantages and disadvantages of glass fiber insulation cotton?
Glass fiber sound insulation cotton advantages and disadvantages are not waterproof, rain or after washing with water in the process, resulting in a substantial increase in dead load, accelerate landing, it is difficult to water evaporation in a short time, and wet part of the body could easily lead to corrosion. In addition, there is no environmental friendly problems which is well known, and it is also a strong carcinogen.
Q:Does glass wool equals to rock wool?
It mainly used in the thermal insulation of air-conditioning ducts, has coarse fibers. Isover has pink glass wool roll mats. Black soft cotton is rubber and plastic. Rock wool is generally dark and the glass wool is golden.
Q:What kind of glass wool products
Glass wool products refers to the use of glass wool made of industrial products, according to the shape is divided into glass wool and glass wool felt.
Q:Does rock wool look like glass wool ?
They are not the same. The main raw material of glass wool is glass with long thin and elastic cellosilk, while that of rock wool is basalt with short and thick rock wool silk. But both are used for thermal insulation. Glass wool is more expensive.
Q:Glass wool can be used at zero degrees
Ultra-fine cotton resin products, -120 ~ 400 ℃
