HTQ-1 composite foaming agent is a strong physical foaming agent. It is made by a special ingredients processing, deformation, and then compound to a strong no polluting physical foaming agent. With good foaming ability and neutral performance, it has very good affinity with water. When mixed with water, it is turned into yellow transparent solution. Moreover, it can produce a large number of bubbles in the cement slurry, these bubbles are independent of each other and uniformly distributed in the cement paste. Meanwhile, they can form a large number of closed pores. Therefore, it can have good effect of heat and sound insulation.
