PET zaj duab xis yog dav siv hauv cov zaub mov ntim vim nws cov khoom zoo thiab lub cev, xws li lub zog siab, zoo pob tshab, tsis muaj tshuaj lom, zoo khoom thiab zoo hluav taws xob rwb thaiv tsev zog. Txawm li cas los xij, nws cov monomers thiab catalysts thiab lwm cov koom haum pabcuam, suav nrog los ntawm cov khoom lag luam, muaj qee yam tshuaj lom thiab muaj kev pheej hmoo rau kev tsiv teb tsaws. Cov teb chaws thoob plaws ntiaj teb tau tsim cov qauv sib txuam rau PET cov kev cai huv rau kev hu rau zaub mov.
European Union (EU) TSIS MUAJ 10/2011 Cov ntaub ntawv yas thiab cov khoom tsim los rau hauv kev sib cuag nrog zaub mov
Qhov tshwj xeeb tsiv teb tsaws ntawm monomers thiab cov ntxiv nyob rau hauv PET, monomers thiab additives thiab by-products hauv PET tau txwv nyob rau hauv (EU) NO.10 / 2011.
Ntawm lawv, hnoos qeev yog hlau tsis zoo (mob toxicity: lub plab hauv plab-nas LD50: 100mg / kg; mob plab plab-nas LD50: 80mL / kg), cov tshuaj lom ntawm cov hnoos qeev yog nyob ntawm nws cov qauv tshuaj thiab oxidation lub xeev, trivalent cesium yog qis dua pentavalent toxic Qaug ntau dua.
Kev kuaj tshwj xeeb kev tsiv teb tsaws chaw rau kab laum nyob hauv EU cov kev cai siv cov kua hauv dej xws li: 3% acetic acid (B), 20% ethanol (C), thiab txiv roj roj (D2).
Rau cov khoom noj uas muaj hydrophilic thiab muaj peev xwm ntawm cov tshuaj hydrophilic, cov khoom noj simulants A, B thiab C tau siv; cov khoom noj hauv qab no pH 4.5 siv rau simulant B; dej cawv cov khoom noj uas muaj cawv cov ntsiab lus tsis ntau tshaj 20% thiab cov uas muaj qee cov organic tiv thaiv, cov zaub mov ua rau pom ntau dua hydrophilicity tau simulated C; thiab cov zaub mov muaj roj dawb nyob rau saum npoo yog simulated D2. Tus qauv thiab lub sijhawm sib tiv tauj thiab lub sijhawm ntsuas kub xaiv qhov tsis zoo ntawm kev siv.
