| titleOfInvention | A kind of leather deliming agent without ammonium salt and without boric acid |
| abstract | The invention discloses an ammonium salt-free and boric acid-free leather deliming agent, which is characterized by taking collagen as a raw material and performing deep hydrolysis under suitable conditions to obtain a hydrolyzate with low relative molecular mass. The deliming agent can form a pH 8-9 buffer system with the ash alkali in the ash skin, and quickly penetrate the ash skin to obtain a soft delimed bare skin. The invention can solve the problem that a large amount of irritating ammonia gas and high-concentration ammonia nitrogen wastewater will be generated in ammonium salt deashing, and the biological treatment effect of wastewater will be reduced by boric acid deashing. The technical problem is that it is an environmentally friendly, easy-to-control, economical and practical deliming agent. |
