Q:Why is glass wool board used in portable house on the construction site?
Low cost
Q:Does mineral wool, rock wool and glass wool board refer to the same kind of board?
No, mineral wool includes aluminum silicate and other thermal insulation board, main material is mineral stone, the main material of rock wool is basalt and mineral slag. the main material of glass wool is glass, so they are different and have different thermal insulation effect and price, in general, rock wool is common.
Q:What is the difference between rock wool and glass wool?
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: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:Glass wool and pef air conditioning insulation material, which one is better?
It's all right to use rubber and plastic, PEF or glass wool, but it is not recommended to use glass wool which has poor waterproof effect, and try to use rubber! Select the appropriate thickness according the local winter temperature, or it will be frozen if it is too thin in winter.
Q:Are there any differences between rubber and plastic thermal insulation materials and glass wool thermal insulation materials? Which one is better, please tell me more about it.
Rubber and plastic thermal insulation materials have a lifetime as long as the building itself, and rubber and plastic thermal insulation materials are more convenient and easier to handle in construction.
Q:Which is more suitable for industrial pipe insulation: glass wool or rock wool ?
Glass wool can only be used in about 260℃, but the highest operating temperature of rock wool is about 600℃. It is easy to construct and install, and can be used for many years with good effect of energy conservation, suitable for small storage tanks and cambered surface with small surface curvature radius and equipments with irregular surface. Rock wool has low heat conductivity coefficient, usually used in thermal insulation places at 450℃. Glass wool has lighter unit weight, lower shot content and higher cost performance ratio than rock wool, so it is widely used in insulation of general buildings and low temperature pipes, building air condition piping insulation and wall sound absorption. While rock wool felt is a quality thermal insulation material with low heat conductivity coefficient. Rock wool felt, with excellent insulation property and low price, is widely used in insulation for high temperature heat pipelines or electrical equipments. While glass wool is usually used in insulation places under 200℃。 Suitable for pipes with medium and large diameter. Fiber has strong toughness. That depends on your need.
Q:What's the necessary performance tests lass wool used for steel structure need to do?
Generally it doesn't need to do the experiment, but some party A will demand for thermal insulation test, you can ask the local supervisor for samples manual and show it to party A, there is no test on steel structure columns.
Q:Is glass wool felt the mineral wool felt?
No.
