Q:Whose thermal insulation performance is the best between glass wool felts and cystosepiments?
The construction methods are different. The cystosepiments are certainly better than glass wools. But cystosepiments are rigid plates, while the glass wool felts are soft. From the thermal insulation property,
Q:What kind of glass wool is used for most buildings?
Ask the dealer for product descriptions, and you can search its specifications and parameters and then design based on the performance specifications of specific products. I suggest you first determine which brand of thermal insulation cotton to use, or check if the number is in the tolerance range of national standards of the manufacturers, of course, it is a relatively wide range. I recommend Owens Corning ultrafine glass fiber insulation cotton.
Q:What are the differences between glass asbestos and glass reinforced plastics?
Fiber glass contains glass silk. Asbestos gauges are easy to be broken into pieces, you can not see glass in them. Gloves must be put on when holding or dealing with them to prevent them from sticking to your hands. Asbestos have advantages of acid and basic resistance, good insulation properity, and they are firm, almost unbreakable. Therefore, the industrial uses of it are more than 1,000. However, during the exploitation, processing and application of asbestos, there are dust nuisances. Asbestos are known to cause asbestosis of contacts, and now have been recognized in the world as carcinogen for humans.
Q:How many insulation supporting pins are there in one aquare meter of glass wool?
20 is enough
Q:Are there any differences between rubber and plastic thermal insulation materials and glass wool thermal insulation materials? Which one is better, please tell me more about it.
Rubber and plastic materials have a good thermal insulation performance(thermal insulation equipment medium has a lower temperature), the fire rating of glass wool is high(insulation equipment medium has a low temperature), rubber and plastic materials are a little bit more expensive than glass wool materials.
Q:Which has better effect of thermal insulation, glass wool or rock wool ?
Glass wool fiber is irritating to skin. Now ultra-fine glass wool or centrifugal glass wool is usually used. heat conductivity coefficient of glass wool : 0.033 ~ 0.036W / (mK) rock wool: 0.040W / (mK)
Q:How to conduct thermal insulation construction of external wall glass wool?
The construction period of insulation consrtuction of this project takes 20 days, which is a tight schedule, so the insulation construction should be organized properly to ensure the insulation construction period. The insulation construction of Dingfuzhuang secondary school needs to undergo the following process: firstly conduct construction of external wall insulation of teaching building; secondly conduct construction of external wall insulation of laboratory building and finally conduct construction of external wall insulation of cafeteria. Scaffolds of the outer edge of the teaching building have been fully completed, so the four facades of the teaching building can be constructed simultaneously in a bottom-up way. When shotcrete construction of the outer edge of laboratory building finished, it then can conduct insulation construciton of the outer edge of laboratory building. At this time, thermal insulation construction of teaching building have not fully completed, which requires supplement labor force to ensure thermal insulation construction of these two buildings to be conducted simultaneously. When the outer edge of cafeteria is qualified for thermal insulation construction, it needs to supplement labor force for thermal insulation construction, so that these three building can conduct thermal insulation construction simulanteously.
Q:Glass fiber, glass wool, what is the difference
What is the difference between glass fiber and glass wool? Is there a corresponding standard to define it?
Q:What are the advantages of Rock wool and import glass wool respectively?
Rock wool: Also known as rock cotton, mineral rock. With minerals as raw materials, it is fluffy short fine fibers. Main raw materials such as basalt, pyroxenite, dolomite, iron ore, bauxite will be made into fiber rock wool after high temperature fusion, and fiberization. It can be used as high temperature and ablation resistance as well as thermal insulation materials; sound-absorbing and thermal insulation materials for construction equipments. Asbestos alternatives can be used as cement products, rubber reinforcing materials and high temperature sealing materials, as well as high-temperature filter and catalytic carrier, etc. 1. Insulation property: Basic features of Insulation performance of rock wool, slag wool products 2. Combustion performance 3. Sound insulation performance: Rock wool, slag wool products have excellent sound absorption performance. Glass wool belongs to glass fiber. Category: machine-made fiber, molten glass wool glass, fibrosis-like materials, it is the fiber that belongs to glass. Type, bulk density, low thermal conductivity, thermal insulation, sound-absorbing performance, corrosion resistance, chemical stability.
Q:What are the uses of glass wool thermal insulation materials?
They are generally used in steel roofing. and the outer layer of pipes. .
