The first manufacturing procedure of making high strength partition wall board with light weight is compress the air into micro-balls and mix them to 50-70% liquid-slurry which consisting of fly ash, magnesium chloride cement, and concrete. Thus, the interior board will generate many air bubble structure and takes the place of traditional way of adding aggregate and evacuating to reduce the weight of board. The production line can not only produce solid and hollow lathes, but also elementary substance and composite board. Furthermore, it has multiple-function and low energy-consuming properties. The whole installed power rating is less than 30 thousand w. this production line takes PLC control system which manipulated by computer. The quality of the product is stable and reliable by advanced technical formula and procedures under the normal temperate and constant pressure.
