The vermiculite, inorganic auxiliary materials and adhesives are mixed evenly in a certain proportion and put into the mold. After high temperature pressing, it is made into a kind of plate shaped, preserved at low temperature and dried at high temperature. The plate has the characteristics of fire prevention, heat preservation, heat insulation and sound insulation. Hirudite also has a certain strength, it is easy to cut, slot, hole.
