Q:These two kinds of glass wool are used as insulation materials, but one keeps 0.3 in specific gravity while the other keeps 0.5 in specific gravity. Which one should be chosen?
Generally, materials with high density have better insulation effect, consequently leading a relatively higher price. You can make a layer of polyurethane on the outside. Specific gravity is another way of saying density. Materials' thermal insulation effect is related to density. So if you want to get better thermal insulation effect, you can make a layer of polyurethane on the outside. It is noted that common polyurethane has a maximum temperature of 100 degrees, while high-temperature polyurethane requires 120 degrees.
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: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:Whether the combustion performance of glass wool blanket can reach A grade
Yes, it is A grade
Q:Specifications and models of glass wool
Models of glass wool: 32kg / 50mm, 48kg / 50mm, 80kg / 50mm, 96kg / 25mm, 80kg / 25mm
Q:Is the microporous aluminum silicate coated with aluminum wool?
This sentence contains four kinds of material microporous (microporous calcium silicate) aluminum silicate aluminum foil glass wool
Q:What are the advantages and disadvantages of glass fiber insulation cotton?
Since the biological effects of rock wool is similar with asbestos wool , but the severity of harm is much lower than the asbestos, and behavior, transfer, removal in the human body is similar with asbestos and carcinogenic mechanism is also similar. Fibrogenic and carcinogenic effects, must be accumulated as a sufficient number of fibers in the organization as a precondition. Therefore, the contact reduction is the fundamental measures to prevent the occupational hazard of asbestos supplement. Confined dust source: The main closed production machinery.
Q:The advantages of glass wool board
rock wool board is the inorganic fiber which takes the basalt as main raw material, and processing by melting in high temperature. Rock wool board, is also known as rock wool thermal insulation decorative board.
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:What is the difference between anti-high temperature glass wool and ordinary glass wool?
High-temperature glass wool is made of lathy glass fibers without shot. Compared with other kinds of insulation materials, it will not be broken due to water or rain, and it can still remain its insulation properties unchanged after drying in the sun (Thermal insulation materials have hydrophobicity which doesn’t mean that the materials are not hydrophilic but means that the discharge capacity for absorbed moisture). High-temperature glass wool is a thermal insulation material that can resist high temperature with its lightweight, lasting durability and excellent thermal insulation property, the material that is made up of uniform and slender and elastic glass fibers as well as special high-temperature adhesive. The outer protective layer of thermal insulation structure can use galvanized iron sheet based on specific circumstances. Application of high-temperature glass wool: It is widely used in equipment and pipelines of electric power, petroleum, chemical industry, light industry, metallurgy and other industries, serving as the thermal insulation.
