What are the types of insulation materials?

We call the material that controls the outflow of indoor heat insulation, which is also commonly used in construction, so that it can effectively maintain the indoor temperature, such as in the winter can make the indoor temperature warmer. So we are also very important for the purchase of insulation materials, of course, the quality of some of the materials, the insulation effect will be better, but there are many types of insulation materials, so which one of the materials is better, the next small make up to introduce us to all the types of insulation materials.

1, mineral wool, rock wool and its products

Mineral wool is industrial waste slag as the main raw material, melted, with the spray blowing method or centrifugal method and made of cotton-like insulation materials: rock wool is made of natural rock as raw material for mineral wool. Commonly used rocks such as basalt, diorite, hornblende and so on.

Mineral wool features: mineral wool and products is a high-quality insulation materials, has more than 100 years of production and application history. Its lightweight, thermal insulation, heat insulation, acoustic, chemical stability, non-combustible, corrosion-resistant, and raw materials from a variety of sources, low cost.

Mineral wool main purpose: its products are mainly used for dry building walls, roofs, ceilings and other places of thermal insulation and acoustic, can also be made into a waterproof felt and pipe casing.

2, glass wool and products

Glass wool is made of glass raw materials or crushed glass melted into a fibrous material, including short cotton and ultra-fine cotton two.

Glass wool features: at high and low temperatures can maintain good thermal insulation properties; has good elastic recovery; has good sound-absorbing properties of a variety of acoustic waves, noise have a good sound-absorbing effect; chemical stability, no aging phenomenon of long-term use of the performance of unchanged product thickness, density and shape can be processed according to user requirements.

Main application: short cotton is mainly made of glass wool felt, felt rolls, used for building insulation and sound insulation, ventilation, air conditioning equipment, thermal insulation, sound insulation. Ultrafine cotton is mainly made of glass wool boards and glass wool tube sets. With dry large recording studio, cold storage, warehouses, ships, aviation, tunnels, and housing projects of thermal insulation, sound insulation, can also be used for heating, water supply, power and other equipment pipeline insulation.

3, aluminum silicate cotton and products

Aluminum silicate cotton that is the diameter of 3 ~ 5?m aluminum silicate fiber, also known as fire-resistant fibers, is based on high-quality pyroxylin, high-purity alumina, silica, zirconia sand as raw materials. Select the appropriate technology processing, melt by resistance furnace blowing or dumping, so that the chemical composition and structure of the same and different dispersed materials for polymerization of fibrous inorganic materials, is currently recognized at home and abroad, a new type of high-quality thermal insulation materials.

Features: light weight, high temperature resistance, low heat capacity, low thermal conductivity, excellent thermal stability, excellent tensile strength and excellent chemical stability.

Main application: widely used in electric power, petroleum, metallurgy, building materials, machinery, chemical industry, ceramics and other industrial sectors, industrial kilns, high-temperature insulation closed as well as used in filtration, acoustic materials.

4, asbestos and its products

Asbestos, also known as "stone wool", is a commercial term for mineral silicate products with high tensile strength, high flexibility, chemical and thermal erosion resistance, electrical insulation and spinnability. It is a general term for a natural, fibrous, silicate-like class of minerals.

Features: highly fire-resistant, electrical insulation and thermal insulation. Is an important fire, insulation and thermal insulation materials.

Main application: mainly used in dry mechanical transmission, braking, and thermal insulation, fire protection, heat insulation, corrosion, sound insulation, insulation, etc., which is more important is the automobile, chemical industry, electrical equipment, construction and other manufacturing sectors.

5, inorganic microporous materials

(1) diatomaceous earth: diatomaceous earth is composed of amorphous SIO2, and contains a small amount of fe2o3, CaO, MgO, al2o3; and organic impurities.

Characteristics: diatomite is usually light yellow or light gray, soft, porous and light, its void rate of 50% ~ 80%, so it has good thermal insulation properties. The chemical composition of diatomaceous earth is water-containing amorphous SIO2, and its maximum service temperature can reach 900℃.

Main application: It is commonly used in industry as thermal insulation material, filtration material, filler, abrasive material, raw material of water glass, decolorant and catalyst carrier.

(2)Calcium silicate and its products: calcium silicate insulation material is 65% silicon oxide (quartz sand powder, diatomaceous earth, etc.), 35% calcium oxide (also used slaked lime, calcium carbide slag, etc.) and 5% reinforcing fibers (such as asbestos, glass fiber, etc.) as the main. Glass fiber, etc.) as the main raw material, after mixing, heating, gel, molding, steam hardening, drying and other processes made of a new type of thermal insulation materials.

Features: small apparent density, high flexural strength, small thermal conductivity, high service temperature, good water resistance, strong fire resistance, non-corrosive, durable, and its products are easy to process and install.

Main application: widely used in metallurgy, electric power, chemical industry and other industries, heat pipe, equipment, kiln thermal insulation materials, housing construction of the internal and external walls, flat roof of the fireproof covering materials, all kinds of ships, barn walls and aisle fireproof thermal insulation materials.

Above we introduced to you about the types of insulation materials what are the relevant issues, for these materials we should have some understanding of it. Insulation material has a variety of types, and we know that each type of insulation material insulation effect is different, so we can learn more about some of the various properties of the insulation material when we buy, in this case can help us buy insulation material. Above we introduced some of the types, we can also do for reference when shopping.
