The line will process into material storage system, automatic feeding systems, filling material mixing system, molded plate machine, stripping systems, mold circulatory system, cutting system; a roll forming products, can produce sandwich panels. Mixing station can match four trigger lightweight partition board production line manufacturers, a board production line can achieve 500 square meters of finished class production, automated production process control light partition board formula, each production line labor required 7-8, When using concentrated stirred plurality of lines, the employer can save 1/3 of lightweight partition board, which greatly improves the efficiency of production of light partition board price, shortening the production period. After work easy: Because it is porous, plus products can nail, to dig, to drilling and other general machining, so the water, electricity and other construction pipeline installation and embedding are more convenient than all panels. Wall installation and clay bricks, hollow brick pieces compared to the wet installation work, construction progress difference of 30 times, can greatly shorten the construction period. Strong plate surface can be directly paint or coating. After the paint can be attached to a variety of wallpaper.
