1, random upper and lower sheets tendons, increasing sheet strength. 2 key breakthroughs hard materials card, blocking, destroying machine phenomenon. 3 out of components using special materials, increase the number of times the wear resistance, reduce maintenance and reduce costs. 4, waste utilization, the production of low cost, high yield. 5, the new lightweight partition board binding material for the 425 # ordinary portland cement, the use of slag, fly ash, slag and other industrial waste. Waterproof, deformation, thermal insulation, sound insulation, increasing the building area. The board found JG3063-1999 ministerial standards. The device can produce within the wall board and insulation board, also can produce wall panels, size precision, the construction speed and so on. The new lightweight partition board extruder production of lightweight partition board has a light, large, hollow, Lee spent, excellent performance, no baking, no steam curing, unique, low cost, construction efficiency high wall material in full compliance with the direction of development.
