Zinc stearate is a lubricant and release agent that can be used in plastics, rubber, txheej, inks, paints, thermal paper and cosmetics. It can be used to increase the smoothness and thickness of products, reduce the friction coefficient and improve the texture.
Uses for zinc stearate:
Feem ntau, the use of zinc stearate in products is as a release agent, heat stabilizer, lubricant and grease. It is widely used in the plastics, rubber, coatings and inks industries.
In rubber production, zinc stearate can be used as an internal lubricant and dusting agent and as an activator for vulcanization. It also can be used in powdered rubber manufacturing as a mold release lubricant.
The invention discloses a method for preparing a stable aqueous dispersion of nanometer sized zinc stearate particles. Txoj kev no haum tshwj xeeb rau kev npog cov hmoov toner rau saum npoo. Kev faib tawm tuaj yeem npaj tau los ntawm ib txoj kev yooj yim uas tsis tas yuav siv cov tshuaj organic nyuaj.
Ib txoj kev npaj kev faib dej ruaj khov yog yaj zinc stearate hauv dej thiab tom qab ntawd ntxiv ib qho surfactant. Qhov no tuaj yeem ua tau hauv txoj kev tswj tau los ntawm kev kho qhov kub thiab siab ntawm dej.
Ib txoj kev ntxiv los npaj ib qho dej ruaj khov zinc stearate emulsion yog los txav cov sib xyaw ntawm stearate uas muaj hlau nrog dej thiab ib qho kua ntawm zinc ntsev, nyiam siv txoj kev sib tov muaj zog siab. Zinc ntsev tej zaum yog stearic acid lag luam, ib qho imide, lossis ib qho polyamide-muaj zinc.
