Abstract
Inventia se refera la un procedeu continuu de tabacire a pieilor de porci, care, în scopul reducerii consumului de materii auxiliare, consta în cenuserirea în trepte a pieilor cu 3,5% sulfura de sodiu si 12% var, urmat de decalcifiere, samaluire si spalare, dupa care se tabacesc cu un adaos de 20...30% apa, la temperatura de 28...30 degree C, 1,5...1,7% flatat de sodiu, se agita 30 min, urmat de adaugarea a 1,6...1,8% Cr2O3 de bazicitate 33...35%, agitându-se timp de 2 h la un pH al flotei de 3,8, bazificarea realizându-se în doua parti cu 0,2...0,3% carbonat de sodiu, dizolvat în 30...40% apa, la temperatura de 60 degree C, timp de 90 min, la un pH de 4,0...4,2 si o temperatura de 38...42 degree C.The invention relates to a continuous tanning process for pigs, which, in order to reduce the consumption of auxiliary materials, consists in the stepping of the skins with 3.5% sodium sulphide and 12% lime, followed by decalcification, washing with 20 ... 30% water at 28 ... 30 ° C, 1.5 ... 1.7% sodium laquer, shake for 30 min, followed by adding 1.6 ... 1.8% Cr2O3 of 33-35% basicity, stirring for 2 hours at a pH of the fleet of 3.8, basing in two portions with 0.2 ... 0.3% sodium carbonate dissolved in 30 ... 40% water at 60 ° C for 90 minutes at a pH of 4.0 ... 4.2 and a temperature of 38 ... 42 degrees C.
