Our company is the first company in China to use the pregelatinized secondary high-temperature & high-pressure synthesis technology. The xonotlite products obtained by using the 400 degrees centigrade,2.7MPa synthetic steam have the characteristics of high heat resistance and flexural strength. The highest heat resistance temperature is up to 1100 degrees centigrade, raising 100 degrees centigrade than the same calcium silicate products which synthesized by using saturated steam of 220 degrees ...
