Kev daws Polymerization
Qhov no yog txoj kev siv ntau tshaj plaws rau kev tsim cov acrylic matting resins. Siv cov kuab tshuaj xws li xylene, monomers thiab cov thawj coj tau ntxiv dropwise ntawm tus nqi tsis tu ncua thaum cov sib tov refluxes ntawm kwv yees li 140 degree. Tom qab ntawd, cov kuab tshuaj raug tshem tawm ntawm lub tshuab nqus tsev distillation, thiab cov khoom yog txias thiab pulverized kom tawm los ntawm cov khoom siv. Cov khoom tsim tau muaj kev ua haujlwm ruaj khov thiab tsim nyog rau kev siv hmoov txheej.
Lwm Txoj Kev Polymerization
Emulsion polymerization yields dej -raws li matting acrylic emulsions ncaj qha; tus kheej- cov teebmeem matting yog ua tiav los ntawm kev sib txuas cov khoom latex ntawm ntau qhov sib txawv. Suspension polymerization thiab bulk polymerization feem ntau yog siv los ua cov khoom dav dav -cov khoom siv acrylic thiab tsis tshua muaj kev ua haujlwm ncaj qha rau matting - cov khoom qib.
Cov Ntsiab Cai Tswj Cov Ntsiab Lus
Lub epoxy sib npaug qhov hnyav yuav tsum tau tswj ntawm kwv yees li 570 g / eq los tiv thaiv cov qib gloss txawv txav lossis txo qhov yooj yim (khoov tsis kam).
Lub iav hloov pauv kub (Tg) yog tsim los kom poob rau hauv 50-90℃ntau yam kom ntseeg tau tias ob qho tib si cov nyhuv matting thiab cia ruaj khov.
Cov tshuaj tiv thaiv kub yog khaws cia ntawm kwv yees li 140℃los tiv thaiv monomer vaporization los ntawm kev cuam tshuam nrog cov txheej txheem polymerization.
