Q:Does anyone know about the filling materials in the steel stud, is it glass wool or mineral wool?
They are very similar, both have advantages of fireproofness, sound and thermal insulation. While the glass wool has better sound insulation performance, and the rock wool has better fireproofness. The glass wool is white, and the rock wool is gray.
Q:Are rubber and plastic thermal insulation material and glass wool in air conditioner energy-saving materials ?
They almost are.
Q:What are the disadvantages of glass wool? What are the technical limitations in application?
Each insulation material has its own advantages and disadvantages. Let's take glass wool and rock wool as an example. Glass wool is less irritating to the workers' skin than than rock wool is in construction workers, but we can not say that the glass wool is not irritating at all. Besides, the melting point of glass wool and rock wool is different. The thermal insulation effect of glass wool is better than rock wool when they have the same bulk density and thickness.
Q:Does rock wool refer to the glass wool?
Rock wool is not glass wool, ~ ~ ~ two kinds of products, appearance, price, performance are different, have obvious difference.
Q:What's the difference between rock wool board, glass wool board, glass wool felt?
First question: These three products are used for thermal insulation in roof and wall surface, ship, equipment respectively. Second question: specifications: Rock wool board: 1000 * 630 1000 * 600 1200 * 6001200 * 630 Density is 60-100KG / M3. Imported and exported density is 60-100KG / M3. Glass wool board: 1200 * 600 density: 20-40KG / M3 Glass wool felt : width:1200 density:10-30 [For exoprt] Third question: They can all reach Class A non-combustible. Fourth question: Rock wool board is waterproof and fireproof while glass wool is only fireproof. Fifth question: They can all use tinfoil. Glass wool felt needs to be vacuumized because it has low density. [These are what customers need. ] Sixth question: Add me, and I will inform you the latest changes. Seventh question: It can be used in other ways. Contact me for pecific price.
Q:What is the highest temperature that the fireproof glass cotton can resist?
It has good thermal insulation which is based on the thermal conductivity (λ=0.043W/m2K) of glass wool.It also has excellent fireproof performance and it can resist over 1000 ℃.
Q:What is the difference among rock wool board, rock wool and glass wool?
Rock wool is a kind of mineral wool. It takes natural rocks and minerals and other mateirals as raw materials, and formulates fluffy short fiber. Glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. 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:Whether the rigid section of aluminium foil glass wool can be twined with glass fiber cloth
This is not necessary, it depends on the place the shell is used, the best thing is to add a layer of insulation tape.
Q:The main classification and difference of glass wool
And then the application of atomized binder, in the cotton net with the negative pressure of the wind, attached to the resin binder fiber calm in the movement of the mesh belt, forming a uniform cotton felt,
Q:what is the specification of glass wool sound-absorbing board?
General specifications include 600 * 600600 * 500 * 1200-1200/12000300/400 mm thickness is usually 14 to 22 mm. . Glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. 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. Centrifugal glass wool belongs to porous materials and has good sound absorption performance. Centrifugal glass wool can sound-absorbing reason is not due to the rough surface, but because of there exist a large number of internal and external connected tiny pore and holes. When sound waves enter on the centrifugal glass wool, sound waves can follow the internal pore into inner material, cause the vibration of air molecules in space. Because of the friction of air viscous resistance and air molecules and pore wall, sound energy is wore down after being transferred into heat energy.
