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:What are the industry standards of glass wool and its products?
The industry standards of glass wool and its products GB / T 13350-2000. The standards specifies classification, requirements, testing methods, inspection rules, marking, labeling, packaging, transportation and storage of glass wool for thermal insulation and its products. It also give the conversion of thermal resistance and thermal conductivity coefficient. This standard applies to insulating glass wool, glass wool board, glass wool band, glass wool blanket, glass wool felt and glass wool tube.
Q:Which one among polystyrene boards, rock wool boards and glass wool boards is the best materials for external wall thermal insulation?
Polystyrene boards are better in terms of external wall thermal insulation materials but now polystyrene boards are not allowed to use. Rock wool and glass wool can be used, but they need good waterproofing treatments.
Q:How much is the Dalian glass wool fireproof panel?
Glass wool fireproof panel--A Grade fireproof panel Brand / model: Bert | useTemperature: 500 | Brand: Bert Form: Fibrous | core material: Glass fiber| Application: Insulation Price: 3700.00 glass wool - Firewood Brand / model: Party goods | Product Category: Insulation board | Size: 1200 * 1200 * 600 500 Flexural strength: / Mpa | Category: Insulation materials | core material: Fibrous material Price: 220.00 yuan more than the price from the network, for reference purposes only.
Q:What is the fire rating of fireproof sound-insulating glass wool board?
Generally we do not use A1, A2 but A class, which is non-combustible levels. A level is higher than the B level. B-level is divided into B1and B2. B1 stands for flame retardant type and B2 combustible type. rock wool and glass wool both rates A class. secondly, Rockwool can endure high temperature of 800 degrees, glass wool 450 degrees.bulk density of rockwool is heavier than that of glass wool. And glass wool has better waterproof performance.
Q:Where are the differences between the glass wool board and glass wool blanket?
Glass wool felt is generally used to the top of industrial plants, which is roll-like; glass wool board is mainly used for external wall heat insulation, which is board-shaped.
Q:How to conduct thermal insulation construction of external wall glass wool?
I would like to give a brief introduction to the usage of glass wool as the thermal insulation for equipment. 1, Cleaning dust on the surface of equipment. 2, Using adhesive to glue the iron sheet of insulation nails (iron sheet of one square centimeter will be fed in the middle with a slightly harder iron wire of about 8 centimeters) on the surface of the device. Distribution density depends on the weight of glass wool. If insulated cotton is 1 m * 0.5 m, it merely needs to glue seven to eight insulation nails. When glue of iron sheet finished, the device is like a hedgehog. 3. Once insulation nails sticked firmly, it needs to affix to glass wool, fixing it with a piece of spare iron sheet with a hole in the middle of it (it is round and is a set with insulation nails), and then bend the redundant part of iron wire. Wish it will help you. Thank you!
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:Is the glass wool sound insulating? How good is it?
Glass wool glass fiber is a kind of inorganic fiber in the category of glass fiber.The glass wool is of corrosion resistance, chemical stability, low thermal conductivity, low bulk density, thermal insulation and good sound-absorbing property. Besides, the chemical composition of glass wool is glass.
