Khoom Description
Ethylene glycol yog dab tsi?
Ethylene Glycol, tseem hu ua glycol, lossis EG luv luv, yog qhov yooj yim diol. Nws tus lej CAS yog 107-21-1, nws cov qauv tshuaj yog C₂H₆O₂, thiab nws qhov hnyav molecular yog 62.07. Nws yog xim tsis muaj xim, pob tshab, kua nplaum nrog lub qab zib saj thiab hygroscopicity. Lub melting point yog muaj kev pheej hmoo ntawm combustion thiab tawg thaum raug qhib nplaim taws, kub kub, los yog kev sib cuag nrog oxidants. Yog tias raug kub kub, qhov siab hauv lub thawv nce, thiab muaj kev pheej hmoo ntawm kev tawg thiab tawg.

Siv
- Ethylene Glycol tuaj yeem siv los ua cov tshuaj tua kab nruab nrab thiab cov tshuaj nruab nrab, thiab yog ib qho nruab nrab ntawm fungicides pentamethylenetetracycline thiab benomyl. Nws tseem yog cov khoom siv raw rau cov khoom siv tshuaj xws li cov khoom siv hluavtaws; tawv fiber dyes, thiab lwm yam.
- Ntxiv EG rau cov kua dej hydraulic tuaj yeem tiv thaiv cov roj-raws li hydraulic kua los ntawm corroding roj hmab hauv lub cev; dej-raws li hydraulic kua nrog EG raws li lub ntsiab tivthaiv yog tsis yog -flammable hydraulic kua siv nyob rau hauv aircraft, tsheb thiab siab - kub molding tshuab.
- EG tuaj yeem siv los ua cov khoom siv textile, hluavtaws ua kua dyes, thiab cov khoom siv raw rau cov neeg ua haujlwm desulfurization hauv chiv thiab roj refining ntau lawm.
- EG kuj tseem siv tau los ua cov tshuaj ntsuam xyuas, chromatographic tsom xam reagents thiab capacitor media.
