Polyurethane Release Agent
PU (polyurethane) muaj kev sib txuas zoo nrog lwm cov ntaub ntawv. Cov cuab yeej no tsis zoo hauv kev ua npuas ncauj molding. Hauv kev tsim cov molded polyurethane ua npuas ncauj, cam khwb cia polyurethane elastomer thiab lub ntiaj teb no cov tshuaj tiv thaiv kev txhaj tshuaj molding (RIM) thiab lwm yam khoom. Yuav kom tshem tawm cov khoom ntawm pwm sai thiab du, yuav tsum tau siv cov pwm tso tawm tus neeg sawv cev. Nyob rau hauv cov txheej txheem polyurethane molding, tso tawm cov neeg sawv cev yog siv kom tau cov khoom nrog ib tug du nto. Tus neeg sawv cev tso tawm zoo tshaj plaws yuav tsum muaj qhov zoo thermal stability thiab tshuaj lom neeg ruaj khov, tsis corrode pwm, thiab tsis tawm cov khoom decomposition rau saum npoo ntawm pwm; xim muaj peev xwm, thiab lwm yam; yuav tsum tau siv sij hawm me me los ntxuav pwm li sai tau; yuav tsum tsis muaj tshuaj lom, muaj kev nyab xeeb, thiab yooj yim rau kev khiav lag luam; yuav tsum yog tus nqi qis.
