In the current insulation brick market, in order to meet the needs of different environments, there are now many varieties of insulation bricks, and each type of brick has its own characteristics. The following Xinwei refractory material introduces the common types of insulation bricks. Silica lightweight thermal insulation brick Silica lightweight thermal insulation brick uses high-quality silica clay, wood layer and high temperature binder as the main raw materials. It is formed by mixing, extruding, and drying.


Because the product contains a large number of micropores, it has higher compressive strength, lower bulk density, smaller thermal conductivity, lighter bulk density, and safe and convenient construction compared with clay, high alumina, bleaching, and fiber thermal products. It has the advantages of good energy-saving insulation effect and high quality and good price. Lightweight mullite insulation bricks have the characteristics of average, good thermal shock qualitative, high charge, small high cross value, high degree, good resistance to chemical injection, etc. The difference is mainly divided into light weight and heavy weight.


Alumina hollow ball brick is a new type of high-temperature insulation material. It is used at a temperature of 1800 ° C. The product has a high strength, which is several times that of light-weight products, and its volume is only half that of corundum products. One. It is widely used in high-temperature furnaces such as petrochemical industrial gasification furnaces, carbon black industrial reaction furnaces, and industrial induction electric furnaces.


High-aluminum light brick High-aluminum poly-light brick is a new type of thermal insulation of light high-alumina brick series. It mainly uses high-alumina branch and high-purity dry soil, and is filled with polystyrene foam balls. It has the characteristics of high raw material purity, average pore structure, low thermal conductivity, low heat capacity, high strength, and high dimensional accuracy. High warp brick is also called high alumina poly light ball brick, which has high compressive strength, good thermal stability, and can reduce the heat capacity of the furnace.
