STUDY OF FOAMING PROPERTIES OF PROTEIN FOAMING AGENTS BASED ON HYDROLYSATES OF KERATIN-CONTAINING RAW MATERIALS OBTAINED USING SODIUM HYDROXIDE
Protein foaming agents based on hydrolysates of keratin-containing raw materials obtained using alkaline hydrolysis have a set of properties necessary for their use in the manufacture of foam concrete. Protein foaming agents in an aqueous solution and in a cement mixture form a foam with high foaming properties (foam multiplicity, foam volume weight, foam stability). The study of the dependence of the foaming properties of protein foaming agents on the conditions of alkaline hydrolysis of keratin-containing raw materials makes it possible to optimize the hydrolysis process to obtain hydrolysate, which is the main component of protein foaming agent.
