Q:what is the quota of glass wool rigid section of thermal insulation.
Now, I also encountered the same problem, lz, can you tell me what quota should be used?
Q:What's wrong as the glass wool pipe is too soft?
Two cases, one,thickness is too thin; two. Density is too light
Q:what's the differences between glass wool roll mat and rock wool roll mat? does glass wool roll mat have any mandatory retest requirements or environmental requirements?
Steel structure roof basically uses glass wool roll mat, because rock wool roll mat is six to ten times heavier than glass wool roll mat, light steel frame can't bear so much gravity, glass wool is more fluffy than rock wool, so it's thermal insulation effect is better, glass wool is cheaper than rock wool, the glass wool fire rating is A-level flame retardant, now people won't use the rock wool blanket, wall thermal insulation used rock wool board.
Q:What environmental pollutions will be created during the production of glass wool?
It is quite dangerous. Glass wool is very small, such as phenol. If it gets into lungs,the health hazards in the exhaust gas are harmful. If it is on the skin, it will be atingle and itchy. During the production of glass wool, there will be formaldehydes and glass fiber dust.
Q:Does anyone clearly know about the construction technology of glass wool blanket, aluminum net and sound-absorbing wall?
1, the technological process: A layer of dry-laid asphalt felt→ wooden keel installation → install gypsum board → stick glass wool blanket → pave and nail a layer of glass fiber cloth→install aluminum net → fix aluminum net. 2. operation key points of construction methods, embed errosion prevention wooden bricks: During masonry construction, embed corrosion prevention wood bricks (40 × 60 × 60) while laying bricks, with horizontal distance of 400 to 500, and the vertical dimension of 400. I hope my answer can help you.
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. Rock wool is artificial light silicate, not the continuous flocculent fiber material, soft texture, good chemical stability, acid and alkali resistant. Not brittle or pulverization, good elasticity, it can be heat insulation, sound insulation in projects.
Q:Which is more expensive between glass wool and rock wool?
Which Gree factory do you work for? I work for the third factory.
Q:Rubber and plastic or glass wool, which one more suitable for suspended ceiling thermal insulation materials?
The performance will be better, but the quality of glass wool must be considered, the heat conductivity coefficient is the key. But now the quality of the domestic glass wool is not so good, you'd better use rubber and plastic.
Q:Does anyone know about the general unit weight of glass cotton color steel plate?
Glass cotton in the market is generally 16kg / m³ to 64kg / m³. I have also heard about glass cotton with high unit weight, but the higher the unit weight is, the higher the production requirements are, and the boards are more fragile. Glass cotton are manufactured to meet the requirement of large-area pave, apart from the unique thermal insulation property, they are good at fireproofing, shock and sound absorption.
Q:What are the disadvantages of glass wool? What are the technical limitations in application?
Glass wool is one kind of the glass fiber and it is a man-made inorganic fiber. Glass is made by melting such raw materials as quartz sand, limestone, dolomite and other natural ore with some chemical materials like pure alkali and sodium borate. In the molten state, the glass is thrown into fine fibers in the shape of floc by the with external force. These fibres vertically interwine and show many small gaps. These gaps can be regarded as air void. Thus, glass wool can be regarded as porous materials and it is of good insulation and sound absorption performance.
