Kev siv
Resin thiab txheej: diethylene glycole glycol monomethil ether (DEGME) tau siv dav ua ib qho deefent nyob rau hauv resins thiab txheej. Nws tuaj yeem txhim kho cov kua dej thiab cov txheej txheej ntawm cov txheej txheem, txhim kho lawv cov huab cua tsis kam, thiab txo cov pa hluav taws xob tsis zoo.
Cov nplaum nplaum: Raws li cov lus nplaum hauv cov nplaum thiab cov acrylic emulsions, nws tuaj yeem txhim kho cov nplaum thiab yog cov ntoo, thiab cov khoom siv hauv tsev.
Cov Ntaub Ntawv Kev Nyab Xeeb
TOXICICITY: Nws muaj cov tshuaj lom tsawg, nrog cov tshuaj nruab nrab ntawm qhov ncauj kom tuag (LD₅₀) ntawm 9.21g / kg rau nas thiab 6540ML / kg rau luav. Txawm li cas los xij, kev sib cuag ntev lossis kev nqus tau ntawm qhov siab ntawm diethylene glyyl methyth yuav ua kom tib neeg kev noj qab haus huv.
Cov khoom siv kev nyab xeeb: hnav cov hnab looj tes tiv thaiv tus kheej xws li tsom iav kev tiv thaiv thiab tiv thaiv thaum siv, zam kev sib cuag nrog tawv nqaij thiab qhov muag; Khaws qhov chaw ua haujlwm zoo ventilated los tiv thaiv kom nqus tau pa ntawm vapors; Zam kev sib cuag nrog hluav taws thiab cua sov kom tiv thaiv hluav taws thiab tawg; Khaws rau hauv qhov chaw txias, qhuav thiab muaj qhov cua, tsis txhob muaj qhov kub thiab txias, thiab kom tsis txhob sib tov nrog oxidants, acids, alkalis thiab lwm yam tshuaj.
