Abstract

DC60 (05/11/57) It is important to be desired. To obtain a concentrated latex that eliminates protein Then which does not give smoke Ammonia is released through the centrifugal system. Add potassium The hydroxide was added to field latex within 3 hours after incision, to maintain the pH of the fresh latex more than 12. After that, the fresh latex was concentrated. To make the fresh latex rubber particle content greater than 60% by weight and the protein was removed simultaneously through the centrifugation system By adding di-ammonium hydrogen phosphate, anionic surfactant that is Fatty acid salts, disodium salts of ethylene diamine, tetracetic acid, and polyethylene glycol after concentration, maintain potassium content. The hydroxides are contained in from 0.2 to 0.3% by weight of the latex concentrate. This single-centrifugal latex Diluted by the addition of dissolved KOH in water So that the solid content concentration of fresh latex was 26% by weight and added, with di-ammonium hydrogen phosphate, anionic surfactant fatty acid salt, disodium salt of Ethylene Diamine-tetra-acetic acid and polyethylene glycol after concentration, maintain potassium content. The hydroxides are contained in from 0.2 to 0.3% by weight of the concentrated latex. Therefore, this invention combines the KOH double centrifugation and the step-by-step reduction of the protein. The main thing is to be desired To obtain a concentrated latex that eliminates protein Then which does not give smoke Ammonia is released through the centrifugal system. Add potassium The hydroxide was added to field latex within 3 hours after incision, to maintain the pH of the fresh latex more than 12. After that, fresh latex was concentrated.

Therefore, this invention includes a double centrifuge of KOH and gradual reduction of protein
