Product Description:

Good Quality Glass Wool Blanket for thermal Insulation

1.Structure of Glass wool Blanket for thermal Insulation

Glass wool is an industrial product made by spinning glass into a fibrous material that can be packed in mats and Blankets. 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. Numerous companies make glass wool products along with lines of other insulation materials for a variety of applications.

Glass wool raw materials The basic raw materials for fiberglass products are a variety of natural minerals and manufactured chemicals. The major ingredients are silica sand, limestone, and soda ash. Other ingredients may include calcined alumina, borax, feldspar, nepheline syenite, magnesite, and kaolin clay, among others. Silica sand is used as the glass former, and soda ash and limestone help primarily to lower the melting temperature. Other ingredients are used to improve certain properties, such as borax for chemical resistance. Waste glass, also called cullet, is also used as a raw material. The raw materials must be carefully weighed in exact quantities and thoroughly mixed together (called batching) before being melted into glass.

2.Main Features of Glass wool Blanket for thermal Insulation

The glass wool Blanket is applied for large laying area. In the field of insulation materials, we are mainly specializing in Glass wool products, including Blankets, Blankets and pipes. The advantage of this material is numerous: noncombustible, nontoxic, and resistant to corrosion. It has low weight, low thermal conductivity, stable chemical property, low moisture rate and good hydrophobicity. These products have been widely used in heat preservation, thermal insulation and sound absorption in construction, chemical industry, electronic industry, electric power, metallurgy, energy industry, and communication. High density panels laminated with facing can be used for Air-conditioning duct system.

   Where you used this

These products have been widely used in heat preservation, thermal insulation and sound absorption in construction, chemical industry, electronic industry, electric power, metallurgy, energy industry, and communication. High density panels laminated with facing can be used for Air-conditioning duct system.

How to guarantee the quality of the products

We have established the international advanced quality management systemevery link from raw material to final product we have strict quality testWe resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

How you control the quality?

During the production of fiberglass insulation, material is sampled at a number of locations in the process to maintain quality.

use a variety of standardized test procedures to measure, adjust, and optimize product acoustical resistance, sound absorption, and sound barrier performance. The acoustical properties can be controlled by adjusting such production variables as fiber diameter, bulk density, thickness, and binder content. A similar approach is used to control thermal properties.

Q:Which thermal insulation materials are the best for air-conditioners? Is it rubber and plastic, PEF or glass wool?
Rubber and plastic is a better choice for conduits.
Q:Whether the combustion performance of glass wool blanket can reach A grade
Yes, it itself is grade A incombustible material.
Q:Is glass wool felt the mineral wool felt?
No.
Q:What are the specific differences between glass wool board and glass fiber board?
There are two kinds of glass fiber, namely the continuous fiber and staple fiber. The fiber used to weave cloth is continuous fiber, and the fiber used to make cotton is staple fiber. Thus, glass wool board is equal to glass fiber board, and the full name of glass wool is glass fiber wool:
Q:What are the functions of the thermal insulation glass wool board?
Thermal insulation glass wool board has long fibre, low density, low thermal conductivity, excellent heat insulation property, high sound absorption coefficient, heat resistance, flame resistance, freezing resistance, moth repellency and good chemical stability. It has obvious advantages compared with conventional insulation materials.It is mainly used in industrial tanks, piping insulation engineering, industrial plant and steel structure workshop.
Q:What is the uses of aluminum foil glass wool felt?
Glass wool serves as four fuctions to paste aluminum foil paper. Insulation, moistureproof, radiation protection, as well as decorative! Glass wool roll mat selection is based on three aspects. One: Dimensions, thickness of]glass wool roll mat of 50 mm, 75 mm, 80 mm, 90 mm, 100 mm, 120 mm. . Finally, it can be made as long as 200mm.
Q:What is the difference between red glass wool and yellow glass wool in terms of technical parameters?
Thermal insulation properties: Red yellow glass VS Yellow glass wool. Thermal conductivity (K): below 0.039 VS over 0.044; Resilience: good VS poor. Distribution: even VS uneven. Irritation: non-irritating VS irritating and cause itching of skin. Dust: without dust VS with dust. Shot content: zero VS non-zero. Red glass wool is an environmental-friendly material.
Q:Are thermal insulation glass wool boards hydrophobic?
It has poor performance in fireproofing and thermal insulation, and has a high heat conductivity coefficient. At present, it meet requirements of thermal insulation and energy saving policy for external walls. Glass wool is heavy itself, easy to slag. It can lead to serious pollution during construction and produce cancerogenic substance. It is highly absorbent, and easy to peel off. The operation life of which is short.
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 density of high-temperature glass fiber
Glass fiber cotton density is only 1/5 that of water. It is absolute hydrophobic, high temperature resistant with high tensile strength. Glass fiber insulation cotton has low thermal conductivity, good sound absorption, long fiber length, high tensile strength. it is widely used in building air conditioning insulation,decorative wall insulation, ceiling decoration, as well as chemical, electric power industry equipment insulation.
