Product Description:

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.

Q:How many insulation supporting pins are there in one aquare meter of glass wool?
20 is enough
Q:What properties does glass wool felt have?
It has better insulation properties.
Q:How about the quoted price of glass wool board of 96kg?
Glass wool board of 96Kg, soft package of glass wool board , Price: 14 RMB yuan per square meter. Glass wool board, glass wool for buildings, glass wool board of 96kg.
Q:What are the differences between the common and high temperature resistant glass wool boards?
The operating temperatures are different. The common boards can resist 300 degrees, the high temperature resistant one can resist 500 degrees.
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.
Q:What are the disadvantages of glass wool? What are the technical limitations in application?
Each insulation material has its own advantages and disadvantages. Let's take glass wool and rock wool as an example. Glass wool is less irritating to the workers' skin than than rock wool is in construction workers, but we can not say that the glass wool is not irritating at all. Besides, the melting point of glass wool and rock wool is different. The thermal insulation effect of glass wool is better than rock wool when they have the same bulk density and thickness.
Q:Rock wool board and glass wool board, which is more harmful to human body?
Many countries have banned such hazardous substances. The security of glass wool board is high for the asbestos fibers can cause asbestosis, pleural mesothelioma and other diseases.
Q:What is the density of high-temperature glass wool ?
High-temperature glass wool technical performance standard thermal conductivity coefficient(W / (m • K)) 0.037-0.07 GB / T10299 absorption coefficient 0.8-1.0 GB / T10299 combustion performance level non-combustible Class A GB / T8624 average fiber diameter (μm) 5 GB / T3007 slag water content (%) ≤0.3 GB / T5480.5 heat load shrinkage temperature (℃) 500 GB / T10249 binder content (%) 3-10 GB / T10249 use temperature (℃) ≤480 GB / T10249
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:Are thermal insulation glass wool boards hydrophobic?
Do not believe any hydrophobic agents. Products being processed with silicone hydrophobic agents have a short hydrophobic phase, and the performan of which has no guarantee. The thermal insulation performance of A-level glass wool products are poor which may lead to inferior wallboard engineerings.
