Ethylene glycol CAS: 107-21-1

Ethylene glycol, feem ntau hu ua "antifreeze," yog ib qho tseem ceeb hauv cov tshuab cua txias hauv tsheb, qhov chaw uas nws pab tiv thaiv kom tsis txhob kub dhau thiab khov los ntawm kev tswj qhov kub ntawm lub cav. Nws yog sib xyaw nrog dej los tsim cov kua dej txias uas ncig thoob plaws lub cav, nqus cov cua sov ntau dhau thiab hloov mus rau lub radiator rau kev yaj. Tsis tas li ntawd, ethylene glycol siv rau hauv cov cua sov, cua nkag, thiab cua txias (HVAC) ua cov kua hloov cua sov. Hauv kev lag luam tsim khoom, ethylene glycol ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyester fibers thiab resins. Nws yog ib qho khoom xyaw tseem ceeb hauv kev tsim cov polyethylene terephthalate (PET) - ib yam khoom siv yas feem ntau siv hauv lub raj mis, khaub ncaws, thiab ntim khoom. Ethylene glycol kuj tseem siv ua cov kuab tshuaj hauv ntau yam kev siv, xws li hauv kev tsim cov kua mem, cov xim pleev, thiab cov xim pleev. Tsis tas li ntawd, ethylene glycol pom siv hauv kev lag luam tshuaj thiab kev saib xyuas tus kheej, qhov chaw uas nws ua haujlwm ua cov tshuaj humectant hauv cov khoom siv tawv nqaij, tshuaj txhuam hniav, thiab tshuaj kom khaws cov dej noo thiab tiv thaiv kom qhuav. Nws qhov kev ua tau ntau yam ua cov tshuaj tiv thaiv kev khov, cov dej txias, cov kuab tshuaj, thiab cov tshuaj ua ntej qhia txog qhov tseem ceeb ntawm ethylene glycol hauv ntau yam txheej txheem kev lag luam thiab cov khoom siv rau cov neeg siv khoom.
