Mono Ethylene Glycol (MEG) yog dab tsi?
CAS 107-21-1 Mono ethylene glycol (MEG),tseem hu ua EG, 1,2-ethanediol, los yog 1,2-dihydroxyethane, yog cov kua ntshiab, tsis muaj xim nrog cov kua dej me ntsis. Txawm hais tias nws saj qab zib me ntsis, nws yuav luag tsis muaj tsw. MEG yog ib qho kev sib xyaw ua ke uas sib tov zoo nrog dej, cawv, thiab ntau yam organic. Nws cov kev siv tseem ceeb tshaj plaws yog nyob rau hauv kev tsim cov polyester fibers rau textiles thiab ua ib feem tseem ceeb ntawm antifreeze, coolants, thiab aircraft de-icing kua.

Kev Siv Tshuaj Siv Tshuaj Ethylene Glycol (MEG)
1. Tshuaj Intermediates
Methylene glycol (MEG) yog cov khoom siv tseem ceeb rau kev tsim cov polyethylene terephthalate (PET), cov khoom siv dav siv hauv polyester zaj duab xis thiab PET lub raj mis tsim. Cov khoom no muaj peev xwm rov ua dua tshiab thiab muaj kev ruaj ntseg ruaj ntseg. MEG purity ncaj qha cuam tshuam rau tus tsiaj zoo, nrog GC's PET ua tiav kev ua haujlwm tshwj xeeb ntawm 99.9% purity.
2. Polyester Fibers
Muaj Qib Mono Ethylene Glycol yog cov khoom siv tseem ceeb rau kev tsim cov polyester fibers siv hauv cov khaub ncaws textiles. High-purity MEG yog qhov tseem ceeb rau kev tsim cov fibers zoo tshaj plaws rau kev ua haujlwm ntev, kev nplij siab, ua haujlwm, thiab kev saib xyuas yooj yim. Polyester fibers kuj tuaj yeem sib xyaw nrog lwm cov fibers los txhim kho cov khoom tshwj xeeb.
3. Cov dej txias
MEG chemical yog ib qho tseem ceeb ntawm lub cav txias formulations. Nws elevates lub boiling point ntawm cov dej sib tov, txhim khu lub coolant lub peev xwm los tswj lub cav kub. Qhov no tiv thaiv cav los ntawm overheating nyob rau hauv high kub thiab tiv thaiv kom txhob khov nyob rau hauv cov huab cua txias, ua kom pom kev ua tau zoo thiab lub neej ntev.
4. De-icing thiab Antifreeze
Ethylene Glycol MEG yog dav siv nyob rau hauv antifreeze formulations vim nws tshwj xeeb muaj peev xwm los txo qhov khov ntawm dej. Cov yam ntxwv no ua rau nws tseem tsis tau muaj nyob rau hauv cov coolants, aircraft de-icing fluids, thiab anti-icing agents, xa siab -kev tiv thaiv nyob rau hauv mob khaub thuas hnyav.
