The heat insulation material (also known as the insulation material) refers to the pores of materials or material composite body insulation materials that have significant impedance on the heat flow. Low thermal conductivity(≤1.0 w·m-1k-1)material. There are many types of thermal insulation materials, which can generally be classified according to material, use temperature, form, and structure.
(1) According to its internal tissue structure, it can be divided into three categories:
First, porous particles, more common ones include expansion vermiculite and expanded perlite;
Second, porous fibers: common ones are ultra -fine glass wool, asbestos and mineral stalks. This type of material has good thermal resistance and low thermal guidance coefficients. It is usually a single or several composite fiber cloth or felt made of inorganic fibers. It has the characteristics of low thermal conductivity and good temperature resistance. However, glass wool and mineral cotton samples easily absorb water when applying, and produce fiber dust in the air, which is harmful to human health and seriously hinders their promotion and application. In the 1980s, fiber insulation materials occupied a large share in the market. Due to its excellent insulation and fire resistance, it was mainly used for wall insulation of buildings. Because inorganic fibers have many prominent advantages, such as light quality, low thermal guidance and high heat capacity, in recent years, it has been widely used in thermal protection projects of various advanced weapons. The inorganic fibers currently produced in batches include aluminum fiber, glass fiber, quartz fiber, oxide fiber, carbon fiber and silicon carbide fiber.
The third is foaming: including inorganic, organic and organic-inorganic hybrids. Common inorganic categories include foam glass and cement. In the 1980s, due to the advantages of small volume density, low thermal conductivity, high fire resistance and excellent mechanical properties of calcium silicate samples, it is recognized as the best insulation material in the hard block material. Essence But by the 1990s, because of its samples contained asbestos, it was gradually replaced by pulp fiber. But the slurry fiber is not resistant to high temperature, which has significantly affected its high temperature applications. Organic species include phenolic foam, polyethylene foam, and polyurethampies. This type of foam insulation material has low volume density, low thermal conductivity and water resistance, and is widely used in the thermal insulation field.
(2) It is divided into low temperature insulation materials and high temperature insulation materials according to the temperature.
The temperature range of the low temperature insulation material is 600 ~ 900 ° C; the temperature range of the medium temperature insulation material is 900 ~ 1200 ° C; the use temperature of the high temperature insulation material is generally higher than 1200 ° C.
(3) It can be divided into ultra -light and light bricks according to volume density.
Light bricks with volume density at 0.4 ~ 1.3g/cm3; the volume density of ultra -light bricks is lower than 0.4g/cm3.
