(1) The effect of the fresh mortar: ① Prolong the working time and adjustable time; ② Improve the water retention performance to ensure the hydration of cement; ③ Improve sag resistance (special modified polymer powder); (4) improve the workability (easy to construct on the base material, easy to press the ceramic tile into the adhesive).
With the increase of cement dosage, the tensile adhesive strength of ceramic tile after water immersion treatment increases, while the tensile adhesive strength of thermal aging treatment decreases with the increase of excessive cement dosage. The optimal dosage of P· 042.5 cement is 40%.
Resin powder. It's a kind of white powder with good fluidity, which is made of high molecular polymer resin,ultra-fine load anti-consolidation agent and a variety of functional additives.
Internal and external wall putty powder, ceramic tile binder, ceramic tile sewing agent, dry powder interface agent, external wall external thermal insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar external thermal insulation dry mixed mortar.
At present, redispersible latex powder is widely used in concrete due to its good storage stability, storage period, no deterioration due to freezing or water volatilization, simple packaging, convenient transportation, and can be mixed with cement, gypsum and other raw materials at will.
