This kind of foaming agent is based on keratin protein of the hoof horn of an animal (cow, sheep, horse, donkey, etc.) as the primary raw material, adopts a specific process to extract fatty acids, then add hydrochloric acid, magnesium chloride and other additives, heating dissolution, dilution, filtration, high-temperature dehydration, and produce high-grade surface-active substance. The appearance of dark brown liquid, with a particular smell of rot, pH 6.5 ~ 7.5. This kind of foaming agent in animal protein has three types of foaming agents; it is one of the best performance; the foam is the most stable, issued by the foam preservation 24h still has most of the remaining. This is mainly because the liquid bubble film formed by the keratine is very tough, elastic, by external pressure, can be immediately restored to the original state, and is not easy to break. Therefore, the foam concrete pores it produces are mostly closed ball type, with few connected holes. Animal blood gum foaming agent: This foaming agent is animal blood as raw material for hydrolysis, purification, concentration and other processes. Because of the high price of animal blood and food, the resources are limited, and the production cost of foaming agents is high. Therefore, its production and application are less than the first two, and it needs a competitive advantage. According to the development trend, it can not be widely used.
