Qhov tshwj xeeb cob rau kub yaj txoj kev kos xim yog M2000A tsim los ntawm peb lub tuam txhab tom qab xyoo ntawm kev tshawb fawb. Nws yog ua los ntawm rosin, siab molecular polymer, unsaturated dibasic acid, thiab polyol tom qab polycondensation thiab esterification, ntxiv cov cua sov stabilizer, lub teeb Ua tom qab stabilizer. Piv nrog rau cov tsoos rosin hloov kho txoj kev kos cov xim pleev xim, cov resin no tuaj yeem ncaj qha hloov 60% -80% ntawm cov roj av resin hauv cov roj av cov txheej txheem kub-kua txoj kev kos xim, thiab nws muaj kev ua tau zoo dua li cov rosin resin system kub. -melt txoj kev kos xim xim. Cov kab painting muaj ib tug zoo leveling nyhuv thiab gloss.
Khoom nta:
Cov mis tshwj xeeb thiab cov txheej txheem yog hloov kho los ntawm ntuj resin acid. Ntxiv nrog rau nws lub teeb xim thiab lub siab softening point, nws muaj peev xwm ua tau zoo dua lub teeb pom kev zoo, kev nqus ultraviolet, kev ntes dawb radical, peroxide decomposition, thiab nquag oxygen txo cov yam ntxwv. Cov khoom siv cob qhia no tshwj xeeb tsim los rau kev kos npe. Txoj kev kos xim xim npaj los ntawm kev siv cov resin no tsis ua rau muaj kuab paug rau qhov chaw tsim kho. Nws muaj cov yam ntxwv ntawm kev ua haujlwm siab, hnav tsis kam, muaj kuab paug tsis kam, nruab nrab qib, thiab ziab nrawm nrawm. , Thiab muaj qhov zoo ntawm qhov zoo yellowing kuj thiab aging kuj.
