Q:Why does glass wool turn black when exposed to heat? Wether it will ffect the thermal insulation effect.
This is dut to the charring of glass wool before dealing with thermal insulation. When the temperature exceeds the maximum operating temperature of glass wool, it will char. This will have some impact on the insulation effect, so it is better to know the highest temperature of the thermal insulation material before using.
Q:How many insulation supporting pins are there in one aquare meter of glass wool?
From my experience, the interval of 300 is possible. The design value of uplift is determined by the parts of insulation. And the exterior wall, self-weight, etc. is caculated based on the uplift test of the stud. It asks for strict methof or air duct, involving wind load; And it is also based on the load.
Q:Behind the wall at the head of bedroom is an elevator, but how can indulate sound? Waht do you think if install silicic acid board of 12 centimeters plus glass wool and splint fo 9 centimeters and then nail soft package background in the rear?
Soundproofing measures: if conditions permitted, it probably can make soft pakage.
Q:who knows the construction technology of glass wool board?
Construction Technology of glass wool board is very refined, and it is more professional. apply one layer of dry laid asphalt → → wooden keel installation→ → install gypsum board glass wool blankets → Paste a layer of glass fiber cloth → → mounted on an aluminum mesh → → fixation of aluminum mesh. I think it is very commendable technique.
Q:What's the difference between the rock wool and glass wool?
Glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. Taking quartz sand, limestone, dolomite and other FIR stone as main raw materials, and is melted into glass after mixed with some pure alkali, sodium borate and other chemical raw materials. In melting state, transfer them into flocculent fibers under the effect of external force, fiber and fiber are in three-dimensional crossing and winded with each other, presenting many little gaps. The gaps can be regarded as air voids. Therefore, glass wool can be regarded as porous materials, it has good heat insulation and sound absorption performance. Glass wool is a kind of spongiform material shaped by making melten glass fibering, it's chemical content belongs to glass and is a kind of inorganic fiber. It has good molding, small bulk density, low thermal conductivity, good thermal insulation and heat insulation, good sound absorption, corrosion resistance and stable chemical performance.
Q:Which is more expensive between glass wool and rock wool?
Relatively speaking, gass wool is more expensive.
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:What is the density of glass wool?
Name: Common glass wool. Fibre diameter (um) & lt; 15 Apparent density (kg / (m ^ 3)) 80 ~ 100 heat conductivity coefficient at room temperature (W / (m * K)) 0.052 Heat resistance (℃) ≤300 sound absorption coefficient - Notes : 1. The temperature should not exceed 300 ℃. 2. The corrosion resistance is poor. Name: Common ultra-fine glass wool fibre diameter ... Name: Common glass wool fibre diameter(um) & lt; 15 Apparent density (kg / (m ^ 3)) 80 ~ 100 heat conductivity coefficient at room temperature (W / (m * K)) 0.052 heat resistance (℃) ≤300 sound absorption coefficient - Notes: 1. The temperature should not exceed 300 ℃. 2. The corrosion resistance is poor. Name: Common ultra-fine glass wool fibre diameter (um) & lt; 5 Apparent density (kg / (m ^ 3)) 20 normal temperature at room temperature (W / (m * K)) 0.035 Heat resistance (℃) ≤400 acoustical absorption coefficient ≥0.075 Note: In general, the temperature should not exceed 300 ℃ detail
Q:Does anyone know about the specifications of formaldehyde-free glass wool boards?
Product Category: Category of glass wool products: Brand of thermal insulation board: Applications: JG149-2003 Texture: Level of mineral fibers: Origin of A-level products: Langfang, Hebei. low temperature bending ≤: -Operating temperature: 600 The heat conductivity coefficient(room temperature): 0.035 Form: Fibrous Shape: Rectangular. Compressive strength: - Anti-bending strength: - Breaking elongation: - Core materials: Glass wool
Q:The difference between glass wool of 50mm and rock wool.
Glass wool belongs to one of the glass fiber. machine-made fiber cotton wool molten glass fibrosis cotton material belong to glass fiber. type, bulk density, low thermal conductivity, thermal insualtion, acoustic insualtion, anticorrosion, stable chemical performance. Rockwool is also called mineral wool. Use Guangde Shida rock wool and mineral raw materials to make fluffy short fine fibers. Basalt rock wool, pyroxenite, dolomite, iron ore, bauxite can be used to make matrix fiber by going through high temperature melting process and fibrosis.
