1100℃ Silicon Calcium Board

High Temperature Heat Insulation Silicon Calcium Board is used at a higher temperature, generally around 1100 ℃. It is asbestos free. The production process of high temperature calcium silicate board is more scientific and has higher technology. The main components are SiO2 and CaO. It is packed in cartons and pallets, which is convenient for land and sea transportation. It is a first-class qualified product with TRR brand.

Description

1,Description
The forming method of the product is different from that of medium temperature calcium silicate product. It is a dynamic hydrothermal synthesis method. The ratio of calcium oxide to silicon dioxide in medium temperature product is about 0.8, and the ratio of calcium oxide to silicon dioxide in high temperature product is about 1.0. The final chemical in the qualified product is calcium silicate, and the use temperature is 1000-1100℃.1100℃ calcium silicate board is a microporous structure, with a micropore rate of more than 90%, excellent thermal insulation performance and good durability. After long-term use, there is no pulverization of ceramic fiber felt and the decline of thermal insulation, and the service life is up to 8-10 years.
