Q:Why use reflective paper for pipeline package? Such as the caliduct in home is wrapped with a layer of reflective paper outside a layer of glass wool.
Yes, light reflection can prevent the pipe from absorbing too much heat. Its ok if you don't use reflective material but use material which doesn't absorb heat and has light colors, like sack
Q:How is the insulation property of glass wool color steel plate?
Glass wool thermal conductivity coeffieciency is 0.043. rock wool is 0.041 with better thermal insualtion. Since the insualtion and fireproof properties of the rock wool are better than the glasswool, rock wool is more expensive. rock wool is operated at construction site while glass wool is directly operated in the production line.
Q:Can glass wool be used in exterior wall for thermal insulation?
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. Glass fiber cotton, if used in buildings, its surface always is attached to veneer with somewhat certain acoustic transmission effect, such as of plastic film, metal screen, window screen, fireproof cloth, glass cloth and other materials with less than 0.5mm, basically able to keep the original sound absorption property.
Q:Does anyone clearly know about the construction technology of glass wool blanket, aluminum net and sound-absorbing wall?
1,4X20 wide aluminum mound layer, fixed with wood screws; 2, the layer of aluminum net; 3, fix the taut glass cloth on the surface of the keel; 4, stick 40 thick rock wool felt in the keel with construction adhesive ; 5 , 50X50X0.7 fix the light steel keel to the wall with expanded bolts, two-way medium range of 450-600; 6, polymer waterproof coating moisture barrier; 7, 8-10 thick 1: 0.5: 3 cement gypsum mortar layered leveling;
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.
Q:Does curtain wall glass wool belong to thermal insulation wool?
, the general it is mineral wool.
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 density of high-temperature glass fiber
glass wool density is generally between 16K ~ 32K, mainly used for acoustic and thermal insulation, but easily casues layering. Harmful substances comes out at the first heating. it is cheap. The density of the glass fiber acupuncture felt is 110~180kg/m3. It is mainly used for environmental protection, sound-absorbing. it has better fireproof property but it is more expensive.
Q:What are the purposes of centrifugal glass wool?
What is centrifugal glass wool, and what are the purposes of it?
Q:what's the temperature the high temperature glass wool endure?
400 degrees
