CAS 107-21-1 Ethylene Glycol (MEG) Rau PET, Polyester thiab Antifreeze
MEG hauv PET thiab Polyester Applications
Hauv kev lag luam PET, monoethylene glycol reacts nrog purified terephthalic acid (PTA) los tsim PET resin, uas yog ntxiv rau hauv lub raj mis yas, ntim khoom noj, films, thiab fibers. High -purity MEG yog qhov tseem ceeb los xyuas kom meej:
MEG rau Antifreeze thiab Coolant
Mono Ethylene Glycol kuj yog ib qho tseem ceeb ntawm cov khoom siv tshuaj tiv thaiv kab mob hauv tsheb thiab cov khoom ua kom txias. Nws cov khoom zoo heev muaj xws li:
- Siv tau qhov chaw khov kho kev nyuaj siab
- Siab kub taw tes
- Kev ua tau zoo ntawm kev hloov hluav taws xob
Cov yam ntxwv no ua rau ethylene glycol haum rau lub cav tsheb, HVAC systems, thiab cov khoom siv hluav taws xob sib pauv.
MEG Basic Properties & Safe Handling
Yam tseem ceeb ntawm lub cev
Mono Ethylene Glycol MEG yog cov kua tsis muaj xim, tsis muaj ntxhiab tsw ntxhiab nrog cov yam ntxwv hygroscopic, thiab nws tuaj yeem sib xyaw nrog dej hauv txhua qhov kev faib ua feem.
Toxicity Notes
MEG Chemical yog tshuaj lom thaum noj, uas ua rau muaj kev phom sij rau tib neeg thiab tsiaj. Cov cuab yeej tiv thaiv kom raug yuav tsum tau hnav thaum txhua qhov kev tuav.
Environmental Considerations
MEG biodegrades maj mam nyob rau hauv ib puag ncig ntuj. Nws cov pov tseg yuav tsum tau muab pov tseg rau hauv txoj hauv kev kom tsis txhob ua rau muaj kuab paug ib puag ncig.
