fireproof Calcium Silicate Board Production Machinery / waterproof Fiber Cement Plate Line
Production conditions
Required Raw Material:
fiber cement board is made of cement ,sand, or any kind of crop straw and inorganic material (such as talcum powder and powder coal ash) after special technology. So this project has low production cost, small investment and fast effectiveness.
