The casting molding method of cement products

Pouring molding method mainly produces assembled light composite wall board, which is composed of fiber cement board or calcium silicate board as two side board, core material using light aggregate such as polystyrene particles, ceramsite, fly ash and cement as cementing material. Greatly reduce the weight of the wall board, and the products have better thermal insulation, heat insulation, sound insulation performance; The double side layer of light composite energy-saving wall board uses 100% asbestos free fiber reinforced calcium silicate board or fiber cement plate (inorganic grade A non-combustible material) to effectively improve the fire resistance of light composite energy-saving wall board. The fire resistance limit of light composite energy-saving wall board formed by the combination of the two (taking 120mm type as an example) reaches more than 4h at 1100℃. At the same time, the wall does not emit harmful and toxic gases at high temperature.

The biggest advantage of light composite energy-saving wall board is dry quick operation, clean installation environment, civilized construction, is a real new green building wall material. The surface density of 120mm thick light composite energy-saving wall panel is 90kg/m", which is 1/4 of the mass of brick wall masonry and 3/4 of the mass of aerated concrete, and is equivalent to 1/5 of the mass of 120mm thick masonry ten double-sided plasted wall. In addition, the thickness is reduced by 40mm compared with 160mm after plastering, and the use area can be increased by 1m "for each 25m2 wall installed.

The main raw materials are silicate fireproof board or fiber cement flat panel, cellulose fiber, ESP polystyrene particles, light ceramsite, early strength Portland cement, polypropylene short fiber, composite resin rubber powder and some additives.
