- Q: Standard for the implementation of glass wool products
- GB / T 13350-2000 "Glass wool and its products for insulation" and GB / T 17795-1999 "Glass wool for building insulation"
- Q: Whether the rock wool is belong to the glass wool product or not.
- Rockwool certainly do not belong to the glass wool products, rock wool is rock wool, glass wool is glass wool.
- Q: What is the difference between quartz wool and glass wool?
- It belongs to quartz fiber. Quartz fiber is a cotton-shaped fiber made up of high purity silicon dioxide and natural quartz crystal. Its purity is 99.95% purity and density is 2.2g / cm3. The tensile strength is 7GPa and the tensile modulus is 70GPa. It has heat resistance, corrosion resistance and softness. At high temperatures, it remains high retention rate, stable dimension, good thermal shock resistance, chemical stability, transparency and electrical insulation. Filament with a diameter of 4 to 10μm can be used for reinforcing. Fiber?diameter of quartz wool depends on use, which in general is about 0.7 to 10μm. Manufacturing methods: (1) Drawing with melting quartz rod or pipe oxy-hydrogen flame, and then jetting it with oxy-hydrogen flame blowpipe to make into quartz wool with a diameter of 0.7 to 1 μ m; (2) Quartz is made into short fibers and the mats with high speed airflow before being melted with flame; (3) Making quartz fibers or rods go through oxy-hydrogen flame or coal gas flame at a constant velocity for the sake of softening them and then drawing them into filaments at a high speed. It is mainly used as the reinforcement of electrical insulating materials, thermal insulating materials and composite materials. It serves as the radome of aircraft nose, the exhaust nozzle of rockets, ablative materials of spacecraft and thermal insulation materials and so on. Glass wool is categorized into glass fiber, which is a manmade inorganic fiber. Glass wool is a material which fibering melting glass to form cottony shape. Its chemical composition belongs to the classification of glass, being an inorganic fiber. So, it is good shaped with small volume density, low thermal conductivity, good thermal insulation and sound absorption properties, great corrosion resistance as well as stable chemical performance.
- Q: What's the performance and difference of rock wool and glass wool fireproofing material?
- 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.
- Q: As for glass wool board and rock wool board, which kind of material is better?
- substitutes of rock wool and glass wool, performance index, the glass wool price is relatively high, less manufacturers.
- Q: Who can tell me about the unit weight of glass wool board?
- Glass wool has a good sound absorption performance in the high-frequency sound. The main factors affecting the centrifugal glass wool' sound absorption performance are thickness, density and air flow resistance, etc. Density is the weight per cubic meter of materials. 1. with the increase of thickness, the low frequency sound absorption coefficient significantly increases, but there is little change in the high frequency (high frequency absorption is always larger). 2. thickness is the same, the unit weight increases, the low frequency sound absorption coefficient also increases; but when the unit weight increases to a certain extent, the material becomes dense, the flow resistance is greater than the optimum flow resistance, sound absorption coefficient decreases.
- Q: Does glass wool equals to rock wool?
- It has advantages of good sound-absorbing , welding and thermal insulation performance, small bulk density, chemical stability, corrosion resistance, and belongs to glass in terms of chemical composition. It is an man-made inorganic fiber, cotton-like material. Glass wool belongs to glass fiber with low thermal conductivity which is a mineral wool. Rock wool is also known as asbestos. Glass wool fiberizes molten glass.
- Q: What are the functions of the thermal insulation glass wool board?
- Thermal insulation glass?wool?board has long fibre, low density, low thermal conductivity, excellent heat insulation property, high sound absorption coefficient, heat resistance, flame resistance, freezing resistance, moth repellency and good chemical stability. It has obvious advantages compared with conventional insulation materials.It is mainly used in industrial tanks, piping insulation engineering, industrial plant and steel structure workshop.
- Q: Glass core material of ultra-fine glass wool
- Ultra-fine glass wool is made from silicon powder through pressing and vacuumizing. So there is a big risk. Once the vacuum leak, powder in the package will fall, causing the package swell. The swell will cause a series of problems in the external walls. STP board with ultra-fine glass wool as core material have the above problems and air leakage risk. But it has little effect on project quality. We have compared these two materials. The product packaging is the same and the main difference is the inner core. Product with ultra-fine glass wool as core material has low heat conductivity coefficient, good thermal insulation effect, while product with silicon powder as core material is not as good as the former and cheaper.
- 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.
