Glass Wool Board For Thermal Insulation

1.Structure of Glass Wool Board for thermal Insulation

Glass wool is an industrial product made by spinning glass into a fibrous material that can be packed in mats and boards. This product is used as insulation and in other applications, like for air filters. It is available through home supply stores and manufacturers can also produce wools for special purposes, like insulation in aircraft, where the standards may be higher for health and safety reasons.    

Raw materials :   Mineral powder of silica , feldspar , Borax, Dolomite , lime,  and also sodium carbonate , …. For the composition of C- glass formula

The molten glass falls into the spinner, which turns on a vertical axis. The spinner’s exterior, in heat-resistant steel, is drilled with a large number of holes. The glass is pushed through the holes by centrifugation and is divided into numerous strands. A powerful jet of hot gas then draws out the fibers.

Glass wool is 100% recyclable. It is manufactured from sand and recycled glass(up tp 80% cullet) and offers a very positive environmental balance sheet. It protects the environment, from the beginning to the end of its life cycle and gives more comfort and savings to the occupants of the buildings it insulates.

They are energy-saving materials, and thermal insulation materials which can reduce the heat exchange with the outside world of the system and improve efficiency.
Q:Where are the differences between the glass wool board and glass wool blanket?
Glass wool board is metal face fireproof board, mainly are rock wool and glass silk wool, which is made by using color coated steel with advanced quality as plane material, continuous fiber cotton rock wool and glass wool as core material, high-density rigid foam polyurethane as rabbet fillings, foaming and solidifying through high pressure, automatic compacting cloth cotton and composing after super-long precise double-track control molding. Performance: ⑦ has good heat-insulating property. 2, has heat insulation and fire partition performance. 3, has excellent sound insulation and sound absorption properties. Glass wool felt is coiled material to meet the needs of large-scale laying. In addition to maintaining the characteristics of heat insulation, it also has very excellent shock absorption and sound absorption characteristics, and has good absorbing effects especially for the low-frequency and various noise and vibration, which helps to reduce noise pollution and improve the working environment. This kind of material can also be arbitrarily cut according to needs in the construction, mainly used for interior architecture, damping system, vehicle, refrigeration equipment adn damping, sound absorption, noise reduction of household appliances, whose effect is very good. Glass wool felt with aluminum foil on the surface also has strong thermal radiation resistance, which is wonderful lining material for high temperature workshops, control room, inner wall of machine room, compartment and flat top.
Q:could experts tell me the producing method of insulating layer for glass wool board?
If you have already taken the composite board as interior wall, you don't have to do the final construction, because the inside and outside layer of composite board have been very smooth and no defects, if you want to do surface construction, there will demand many materials, because there is no surface composite board, but only those with grooves on the market, and the groove itself is for increasing the weight and pressure bearing strength of composite board. Supplement: Glass wool composite board is metal surface fireproof panel, it's mainly made of rock wool and glass wool, it takes high quality coating steel plate as the plane material, continuous cotton fiber, rock wool and glass wool as the core material, high-density hard foamed polyurethane as the tongue-and-groove filling, shaped after high pressure foaming solidified, automatic solid cotton cloth and controlled by the ultra-long precision double track.
Q:what is the specification of glass wool air duct?
Generally specifications of glass wool as airconditioner air duct include: 48 k - 30 mm single folder tendons aluminum foil, cost depends on the brand you use, i recommend three good brands to you: Owens Corning/ isover/Shanghai Huali. price is about 400-500 yuan/cubic.
Q:Is centrifugal glass wool board suitable for home use?
A large number of people think that glass wool boards are harmful and that it will cause itch when contacting with the skin. And the effect is not obvious used in the surface, so it is generally used in the wall sandwich. They are harmless for wool boards have been checked, and only those which have passed the national inspection are allowed to be sold for home use. But do not use it in the surface as it is fiber products.

Q:What is the difference between high density glass wool board and stereoplasm rock wool board?
Centrifugal glass wool uses glass as the main raw material. Glass mixed with a certain percentage of other materials should be fully melted in the glass furnace. The melted solution will flow out of bushing and enter into the centrifuge.In the high speed centrifuge, glass will be thrown into a glass thin stream. Under the effect of high temperature and high speed flame, glass thin stream is further stretched into fibers and sprayed with foggy adhesive. In the effect of negative pressure wind cotton webs, the fibre with resin adhesives falls on mesh belt, forming a homogeneous cotton blanket and then it is solidified in thermostat curing oven. After the shape of it is fixed, the glass wool will become predetermined products after cut and then be packed.The main raw material of rock wool products is fine basalt rock. The basalt rock is made into inorganic fiber after meited under high temperature and processed in the high-speed centrifugal device. Then the arrangement structure of the fibre is changed after it is add with special binder and dust laying oil and put in a special device. In the last step, the product is solidified and become a new lightweight thermal insulation material. Depending on the application, it can be processed into wool board, rock wool blanket and wool shell.Compared with rock wool, glass wool is of lower unit weight, less shot content, lower thermal conductivity, long service life and high tenacity fiber, rock wool. However, the maximum operating temperature of rock wool is about 600 degrees Celsius while the glass wool is only about 260 degrees Celsius.Glass woolwool is generally used in thermal insulation part less than 200 degrees Celsius and is mainly used for thermal insulation in general buildings or low temperature pipes. Rock wool is generally used at thermal insulation part with the temperature of 500 degrees Celsius and is mainly used for heat perservation of of high temperature heat pipes or electrical equipment.
Q:Who can tell me about the unit weight of glass wool board?
Glass wool has a good sound absorption performance in the high-frequency sound. The main factors affecting the centrifugal glass wool' sound absorption performance are thickness, density and air flow resistance, etc. Density is the weight per cubic meter of materials. 1. with the increase of thickness, the low frequency sound absorption coefficient significantly increases, but there is little change in the high frequency (high frequency absorption is always larger). 2. thickness is the same, the unit weight increases, the low frequency sound absorption coefficient also increases; but when the unit weight increases to a certain extent, the material becomes dense, the flow resistance is greater than the optimum flow resistance, sound absorption coefficient decreases.
