What is the amount of tropicin in the calcium silicate board? Or how to define? What is the effect of the content on the quality of calcium silicate board?
This question is not a direct answer. The toe mullite is mainly composed of cement and quartz sand at high temperature and high pressure, produced in the autoclave. Of course, is a high point, increase the stability and strength of calcium silicate board
So that calcium silicate board is actually Tremere to stone crystal with fiber reinforced. If the reaction is incomplete in the autoclave, the formation of the beta-tropicite crystals is not enough, resulting in a sharp decline in the strength of the calcium silicate board, and even cause waste (soft plate).
The so-called calcium silicate board is through the siliceous material (quartz sand) and calcium material (slaked lime) at high temperature and pressure (autoclave) reaction to form terbutaline, and asbestos, pulp and other fibers are skeleton effect. As for the cement, it is the strength of its own use to increase the strength of calcium silicate board, and the use of its own with a small amount of calcium, thereby reducing production costs. But the cement in the calcium silicate board should not be used, otherwise one will bring the calcium silicate board color becomes darker; Second, the most important thing is to increase the deformation coefficient of calcium silicate board, which is the calcium silicate board is The most deadly.
