Tus qauv qauv:
Nyob ruaj khov ntawm chav tsev kub thiab siab, tsis txhob sib cuag nrog oxide tshav kub thiab ultraviolet hluav taws xob dawb radical pib.
Cov khoom no muaj qee yam toxicity. Qhov ncauj LD50 ntawm nas yog 1.0g / kg. Muaj qhov pom tseeb khaus tom qab nqus tau. Cov qib ntawm daim tawv nqaij khaus yog me me, tab sis qhov muag puas yog loj dua. Cov neeg ua haujlwm yuav tsum hnav tsom iav tiv thaiv.
Khaws cia rau hauv qhuav, tsis muaj roj, khaws lub ntim ntim, thiab khaws cia rau hauv qhov chaw txias, qhuav
Ntim hauv galvanized hlau nruas. Khaws rau hauv qhov chaw txias thiab ventilated. Lub tsev khaws khoom yuav tsum mob siab rau thiab tsis sib xyaw nrog lwm yam khoom. Ua tib zoo saib xyuas kev tiv thaiv hluav taws. Anti-polymerization tus neeg sawv cev yuav tsum tau ntxiv ua ntej khaws cia thiab kev thauj mus los.
Raws li ib tug reactive monomer 2-Hydroxyethyl acrylate yog siv raws li ib tug crosslinking tus neeg sawv cev rau resins, yas thiab roj hmab modifiers. Ntxiv mus, nws yog siv nyob rau hauv synthesis ntawm amphilic block copolymer los ntawm nitroxide mediated nyob radical polymerization. Ntxiv rau qhov no, nws yog siv los npaj tuned poly (hydroxyethyl acrylate) los ntawm atom hloov radical polymerization thiab kuj siv nyob rau hauv UV inks, adhesives, lacquers, dag rau tes, thiab lwm yam.
