Q:Does the glass wool can be the grapes thermal insulation in winter?

you need to use the glass?silk to seal the glass wool, then it will be used in all-year-round and the thickness is usually 50 mm.

Q:Centrifugal glass wool board and flexible foam rubber insulation, which one is better?

Glass wool board has good fireproof performance and can endure higher temperature than the rubber material, which is cheap. Rubber material has poor fireproof performance. It has insulation performace no better than other materials.

Q:Centrifugal glass wool board and polyurethane foam, which has better thermal insulation performance?

The performances maybe are similar, of course, glass wool board with different unit weight, will also be different. Techniques are almost the same. Centrifugal glass wool board has better performance than that of polyurethane foam insulation materials in fire resistance.

Q:Who knows the construction scheme of external wall thermal insulation glass wool ?

Glass wool external wall insulation construction shceme: in this project, 50 thick glass wool thermal insulation boards are used, which has became popular in Beijing as external wall thermal insulation material only in recent two years so there are no mature check, acceptance and construction specifications. It is constructed according to the design negotiations, the reference standard, Atlas 10BJ2-11, JGJ144-2004, GB50411-2007. Construction of glass wool is difficult. Therefore, construction scheme should be made according to specification and design requirments and negotiation records before construction. At the same time, we should strengthen control during construction and solve problem immediately and construct in strict accordance with Atlas and technical schedule. The insulation construction period of this project is 20 days. It is very tight so we need to make proper arrangement to ensure insulation construction period. Dingfuzhuang Middle School insulation construction: first teachingl buildings, then laboratory buildings, finally canteen. When the outer scaffolds are all constructed in the teaching building, carry out construction in four facades of the teaching building from bottom to up. When the laboratory building outer is sprayed with concrete, carry out laboratory building outer thermal insulation construction. At this time, more workers are needed to ensure insulation constructions of two buildings carried out simultaneously as the teaching building insulation constructio is not finished. When the insulation project is constructed in canteen outer, add more workers to ensure insulation constructions of the three buildings carried out simultaneously.

Q:Polyester and glass wool, which is better, and why?

It would be fine if children touches it for it is environmentally friendly materials. My suggestion is polyester fiber, but it will be itchy when touching, but it depends on you, the cost of polyester fiber is slightly higher.

Q:Can Kunnai glass wool board and sound absorption blankets be used to maintain sound insulation in hotel floor? Can it decrease half of the noise? How to install?

No, if the amendment of the surface is not good, it will affect the paving of floor and tile. You can select one of these, and you'better use sound insulation felt for it also is waterproof.

Q:Could centrifugal glass wool be treated as cold insulation material?

It depends on the specific requirements, now glass wool is not allowed to use in areas with high fire rating and cold insulation requirements.

Q:Which is more expensive between glass wool and rock wool?

If you focus on the tonnage to measure the price, you will find that glass wool, Owens Corning, for example, is more expensive. If you focus on square meter to measure the price, then rock wool is more expensive than glass wool. That depends on how you would measure the price.

Q:Why does glass wool turn black when exposed to heat? Wether it will ffect the thermal insulation effect.

The burning like alcohol lamp uses glass wool as the substrate. There are two possibilities to take alcohol lamp to do experiment, which containing organic substances. 2. 1, High temperature oxidation. I produce aerogel thermal insulation felt, and I have seen that the charcoal ash produced is attached to the glass wool. It has some impact on thermal insulation effect, but the impact is small.

Q:What are the differences between glass asbestos and glass?reinforced?plastics?

Asbestos also known as "mountain cloth" is a commercial term that refers to silicate mineral products with high tensile strength, high flexibility, heat resistance, and chemical corrosion, electrical insulation as well as spinnability. It is the general term of natural fibrous silicate minerals. It includes two categories, a total of six kinds of minerals(serpentine asbestos, hornblende asbestos, actinolite asbestos, antholite asbestos, amosite asbestos, tremolite asbestos, etc.) Asbestos are made of fiber bundles, while fiber bundles are composed of long and narrow fibers which can be separated from each other. Asbestos, with properties of highly fire resistance, electrical insulation and thermal insulation, are important fireproofing, electrical insulation and thermal insulation materials. Glass?reinforced?plastics(FRP) also known as GRP, are fiber-reinforced plastics which generally refers to the matrix of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin. Reinforced plastics, with glass fiber or its products as reinforced materials, refer to glass fibre reinforced plastics or glass?reinforced?plastics. Due to the different varieties of resin, there are polyester glass?reinforced?plastics, epoxy glass?reinforced?plastics, and phenolic aldehyde glass?reinforced?plastics. They are light and rigid, non-conducting, and corrosion-resistant. They have high mechanical strength, low recycling rate. Machine parts, cars and Ship hulls made of steel can be replaced by them.
