Mono Ethylene Glycol (MEG) yog dab tsi?
CAS 107-21-1 Mono Ethylene Glycol, feem ntau hu ua Ethylene Glycol Antifreeze tab sis kuj hu ua Ethane-1,2-diol, MEG, EG thiab Industrial Glycol. Cov tshuaj formula yog (CH2OH)2, uas yog qhov yooj yim diol. Ethylene glycol yog cov xim tsis muaj xim, tsis muaj ntxhiab, kua qab zib, thiab muaj tshuaj lom neeg tsawg.

99% Monoethylene Glycol Daim Ntawv Thov / Siv
1. Ethylene Glycol feem ntau yog siv los ua polyester fiber, polyester resin, dehumidifying agents, plasticizers, surfactant, hluavtaws fibers,
2. MEG tuaj yeem siv los ua cov dye / number case hnyav, kev npaj ntawm lub cav antifreeze, roj lub cev qhuav dej.
3. Rau kev tsim cov khoom siv hluavtaws, PET, lossis polyester fiber ntau qib PET, lub raj mis qib PET zaj duab xis siv los tsim lub raj mis dej ntxhia.
4. Ethylene Glycol kuj tuaj yeem tsim cov alkyd resins, kuj siv los ua tshuaj tiv thaiv.
