Shellac wax is a natural wax extracted from shellac, which has many uses, such as making shoe polish, car wax, floor wax, etc. Raw Material Preparation The primary raw material for lac wax is derived from lac, a resinous substance secreted by insects (such as the lac bug) that parasitize certain plants. This substance, after collection, processing, and treatment, becomes the raw material for lac wax production. Extraction Methods Solvent Method : During the production of lac sheets using the solvent method, the lac alcohol solution is subjected to freezing treatment to precipitate and separate the lac wax from the solution. This method leverages the property of lac wax having reduced solubility at low temperatures. Soda Ash Method : In the process of producing bleached lac, the property of lac wax being insoluble in soda ash solution is utilized. By adding soda ash solution and heating with stirring, the lac wax is separated from impurities. Subsequent steps such as filtration, ...
