Solid slow-release bio-enzyme pulping complementary bleaching agent and preparation method thereof

摘要: The invention discloses a solid slow-release bio-enzyme pulping complementary bleaching agent which consists of the following components in parts by mass: 20-30 sodium percarbonate, 35-45 perborate, 5-10 metabisulfite, 10-15 EDTA (Ethylenediamine Tetraacetic Acid), titanium dioxide, 6-8 magnesium sulfate, 2-5 sodiumsilicate, 3-8 alums, 2-4 urea, 1-5 oxalate, 0.1-1 part tripolyphosphate, 0.1-0.5 caseinate, 20-80 water and 20-50 thioureadioxide. further preparation method agent. prepared using not only plays role paper pulp, but also has sterilization enzyme deactivation functions on bio-enzymes are deactivated after is completed, energy consumption factories can be effectively reduced, timecan shortened, cost lowered, addition, environment protection burden social alleviated.
