Q:does the glass wool can be used as building materials?

Of course, it can be used as steel structure roofing thermal insulation and also be used as pipe thermal insulation. it can also be used as the central air-conditioner air duct. It belongs to the inorganic insulation material, and widely used in construction. it is also having many applications in the sound insulation and noise reduction.

Q:Does mineral wool, rock wool and glass wool board refer to the same kind of board?

Rock wool is the board made by silk sprayed by basalt, gass wool is the board made by the technologies of broken glass melting and injection. there are many kinds of the heat preservation materials, every different word represents different products.

Q:What is the difference between the glass fiber and glass wool?

Fiberglass is an excellent inorganic non-metallic material. There are many kinds of glass fibers whose advantages are good insulation, heat resistance, corrosion resistance, high mechanical strength, and the drawbacks are brittle and poor wear resistance. It is made from glass ball or wasted glass through high temperature melting, wire drawing, winding and weaving. The monofilament diameter is between several microns and dozens of microns, the same as 1 / 20-1 / 5 of a human hair. Each bunch of fibre precursor consists of hundreds of or even thousands of monofilaments. Glass fiber is usually used as reinforcing material of composite material, electric insulation material, thermal insulation material, circuit board and various areas. Glass wool, a man-made inorganic fiber, belongs to a kind of glass fiber. It is a spongiform material made through fibration of melten glass. It is an inorganic fiber whose chemical components belong to glass, having good formability, low bulk density, low thermal conductivity, good thermal insulation and sound absorption, corrosion resistance and chemical stability.

Q:To reach better sound absorption effect, which should be filled in the keel, glass wool felt / board or polyester fiber cotton felt / board ?

Both materials are inappropriate to used for noise insulation, for glass wool and polyester fiber cotton are sound-absorbing materials. Neither is good for sound insulation. They can be used to prevent echo formation in the room, and their function is to reduce the reflection of sound indoors.

Q:How about the thermal insulation performance of glass wool?

It is good. The heat conductivity coefficient of glass wool is 0.043, the heat preservation property of which is less than that of rock wool of 0.041. The thermal insulation performance and fireproofness are better than that of glass wool, but the price of it is also higher than that of glass wool. But the site construction operation of rock wool is not as good as that of glass wool. If it is a direct composite of production line, then it has nothing to worry about.

Q:What is glass wool board.

Glass wool is fibrillation by the fusion of the glass, adding binder to solidify the material to make the glass wool roll mat, while the glass wool fibre?diameter is contracted by the centrifugation. The difference is in the centrifugation techniques. the centrifugation techniques currently used most frequent is Saint-Gobain's Isover TEL centrifugation technique, which is the originator of glass wool products. At present the domestic glass wool market is gradually expanding, and enterprise Dacheng Quanhe Chemical Co., Ltd. makes a significant contribution to promote the use of glass wool.

Q:Is the glass wool used in curtain wall the thermal insulation wool?

The glass wool used for curtain wall is thermal insulation wool.However, due to the need of fireproofing, the thermal insulation material for curtain wall normally is rock wool.

Q:What is the difference between Kun Nai glass?wool?board and rock wool?

Insulation board made of glass wool board is mainly used for tanks, pipes and equipment insulation; basalt or diabase rock wool board for external wall,roofing insulation. It also used for tanks, equipment and building decorative acoustic absorption or acoustic insulation.

Q:What are the differences between glass wool felts and rock wool board in terms of appearance, and how to distinguish them?

First, the color. environmental glass wool is while, while rock wool is dark.

Q:What are the uses of glass wool thermal insulation materials?

Thermal insulation construction materials
