Insulation mortar powder (dry powder) is a series of cement-based materials for specific products, this product has excellent integration with cement resistance, can be completely dissolved in cement mortar paste backbone, the cured without reducing the strength of cement, while maintaining the bonding effects, film, and flexibility, but also has good weather resistance and stability. With this product the most obvious advantage is its superior bonding properties and crack resistance, after drying, can effectively prevent acid erosion of the wall of air, not easily affected by wet powder, deliquescence, is widely used for bonding mortar, cracking mortar wall material, and can dramatically reduce the cost of production. Polystyrene board mortar technology formula polystyrene board adhesive mortar ① ordinary Portland cement 42.5 # 500kg / T; ② wash the sand 500kg / T; ③ Rm-1017 powder 10kg / T; ④ Hpmc 15s 2-3kg / T; Note: According to preparation of the actual situation, different seasons should use the appropriate formula, the formula is for reference only, the company's technical staff ready to door service. Polystyrene board surface mortar (mortar cracking) ① ordinary Portland cement 42.5 # 400kg / T; ② wash the sand 600kg / T; ③ Rm-1018 powder 12kg / T; ④ Hpmc 15s 2-3kg / T; ⑤ wood fiber 2kg / T; ⑥ pull-resistant fibers (polypropylene staple fiber) 2kg / T; Note: The added amount of polypropylene staple fibers should not be too high, wood fiber and powder would add various additives to increase the workability, water retention and enhancement crack resistance.
