- Q:Which is the more commonly used thermal insulation material between thermal insulation glass?silk wool and rock wool?
- Glass wool is a little better in that it has a lighter volume-weight than rock wool and better water-resistance ability, but it is more expensive than rock wool a lot of density, waterproof performance is better than lighter than wool to wool, but glass wool is more expensive in price per unit. In terms of fireproof effect, rock wool is definitely superior to glass wool. Rock wool has a maximum temperature of 1100 ℃, whereas glass wool has only 600 ℃. In addition, if used in the external walls, since glass wool has a limited volume-weight, which can merely reach at 60 to 90 in general, but rock wool have a volume-weight up to 140, so present-day external walls will not employ glass wool in general. Instead, rock wool is usually available because it is a A-level fireproof material. Glass wool is slightly lower than roock wool in thermal conductivity, while rock wool has longer fiber length. As for prices, glass wool per ton is more expensive than rock wool, but if the price is measured by per square, glass wool then is cheaper than rock wool.
- Q:What is the function of glass wool foil?
- Possessing strong resistance to thermal radiation, glass wool with aluminum foil veneer is excellent lining material for high temperature workshops, control rooms, walls of machine room, compartment and flat top.Aluminum foil veneer is pleasing to the eye and moistureproof.Glass wool is one kind of the glass fiber and it is a man-made inorganic fiber. Glass is made by melting such raw materials as quartz sand, limestone, dolomite and other natural ore with some chemical materials like pure alkali and sodium borate. In the molten state, the glass is thrown into fine fibers in the shape of floc by the with external force. These fibres vertically interwine and show many small gaps. These gaps can be regarded as air void. Thus, glass wool can be regarded as porous materials and it is of good insulation and sound absorption performance.
- Q:What are the advantages and disadvantages of centrifugal glass wool?
- Rubber insulation material and centrifugal glass wool board both have their own advantages. Rubber is of foam texture, soft and delicate, mainly used for air conditioning, whose construction is simple. Centrifugal glass wool board is fiber product, so human body will be allergic, whose temperature endurance is 400 degrees with good thermal insulation effect, mainly used in buildings and underground pipes. They are thermal insulation construction products approved by fire control department .
- 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:How about the thermal insulation performance of glass wool?
- The features of glass wool mainly include light weight, easy installation, high thermal insulation efficiency, low hygroscopicity, and strong vibration resistance. Fibers of raw materials of glass wool are relatively even in terms of length and thickness, they are closely intertwined during processing procedures. The interwoven structure and its heat conduction are at a right angle, which can effectively retain heat. It operates simply during installation and use, simple common tools are needed to cut. Meanwhile, there will not be disjointed or stretched in use. There are a lot of tiny air voids in the glass wool, thus the physical property is also relatively stable. It is commonly used in various heating, ventilation, tank, air-conditioning adjustment, the performance of which is significant. Of course, the glass wool can also be customized, we can make glass wool with special specification according to your requirements. Using glass wool as thermal insulation materials has been a very long time, and we found that in a quite a long comparison test, the thermal insulation performance is fairly stable, which will not lead to accidents in use.
- Q:What is the difference between red glass wool and yellow glass wool in terms of technical parameters?
- The majority of glass wools are yellow, while glass wools with the color of red or other are called color glass wool which are rarely used.
- Q:What is the heat conductivity coefficient of glass wool ?
- Glass wool has high thermal conductivity. The higher the thermal resistance of thermal paste, the poorer the heat-conducting property. Good domestic thermal pastes are Balance Stars DRG series, STARS series from 0.65-3.8W / m-k. Good international brands are Shin-Etsu, DowCorning, Laird and so on. Thermal conducting silica?gel and silicone?grease belong to thermal interface materials. Thermal conducting silica gel is thermal conductive RTV adhesive, a kind of pouring sealant which can be cured at room temperature. The biggest difference between heat conductive silicone?grease and silica?gel is that heat conductive silica?gel can be cured and has a certain bonding property. Thermal conductive silicone?grease is a kind of material used to fill the gap between CPU and cooling fin.
- 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:Does glass wool belong to the asbestos insulation material?
- Asbestos products have many varieties and they are mainly used for thermal insulation in industrial equipment and industrial pipes. The operating temperature is within 600 ℃. Compared with glass wool, asbestos products also have more forms. They include asbestos cloth, rope, tape, sheet, blanket, packing (sealing materials), quilt (for fire suppression) and paper.Glass wool is mainly used for thermal insulation of buildings and air ducts. The operating temperature is within 450 ℃.The main products areglass wool plates and carpets.It need to be noted that asbestos is non-environmentally friendly materials and it is radioactive. Long-term contact with it may do great harm to the human body, thus the production of it is banned.
