Ntshiab ethylene glycol muaj qhov khov ntawm kwv yees li -12.9℃(8.6℃F) thiab qhov kub ntawm 197.3℃(387.1℃F).
CAS Tsis Yog . 107-21-1 Ethylene Glycol, tseem hu ua monoethylene glycol (MEG) los yog 1,2-ethanediol, yog ib qho ntawm feem ntau siv glycols hauv ntiaj teb. Nws yog feem ntau siv rau hauv:
- Automotive antifreeze
- Industrial coolants
- HVAC systems
- Thaum tshav kub kub hloov kua
- Polyester thiab PET resin manufacturing
- Lub dav hlau deicing kua
Ib qho ntawm cov laj thawj tseem ceebethylene glycol CAS 107-21-1Nws yog qhov tseem ceeb heev yog nws cov khoom thermal tshwj xeeb, tshwj xeeb tshaj yog nws qhov kub thiab txias point. Cov yam ntxwv no tso cai rau MEG ua tau zoo nyob rau hauv ob qho tib si siab - kub thiab qis - qhov kub thiab txias.
CAS 107-21-1 EG Boiling Point
Cov ntsiab lus kub ntawm ethylene glycol ntawm tus qauv atmospheric siab yog kwv yees li 197.3 degree; Qhov sib npaug yog 387.1℃F thiab 470.5 K.
Qhov kub kub kub no ua rau MEG haum rau siv nyob rau hauv siab -kub cua kub hloov tshuab thiab cav txias daim ntaub ntawv.
CAS 107-21-1 EG Freezing Point
Lub freezing point (melting point) ntawm ntshiab ethylene glycol yog kwv yees li −12.9 degree; Qhov sib npaug yog 8.8℃F thiab 260.2 K.
Txawm hais tias qhov chaw khov ntawm cov ntshiab ethylene glycol qis dua li cov dej, nws qhov muaj txiaj ntsig muaj tseeb nyob hauv nws txoj kev siv hauv kev sib xyaw nrog dej.

CAS 107-21-1 MEG Raw Khoom Muag hauv Suav teb
Cov ntawv thov kev lag luam tseem ceeb: Raws li cov ntsiab lus Boiling thiab khov
1. Automotive Antifreeze thiab Cav Coolant
Ethylene glycol / MEG tshuaj yog dav siv nyob rau hauv automotive radiator systems vim nws muaj peev xwm:
Tiv thaiv lub coolant los ntawm khov thaum lub caij ntuj no
Tiv thaiv lub cav los ntawm overheating thaum lub caij ntuj sov
Khaws qhov kub thiab txias ua haujlwm rau lub cav
2. Muaj cua sov hloov cov kua
Hauv cov nroj tsuag tshuaj thiab kev lag luam kev lag luam, nws yog siv hauv:
Kub exchangers
Kaw - lub tshuab cua sov thiab cua txias
Txheej txheem kub tswj systems
Nws ruaj khov nyob thoob plaws qhov kub thiab txias ua kom muaj txiaj ntsig zoo thaum lub sijhawm ua haujlwm tas mus li.
3. HVAC thiab tub yees Systems
Ethylene glycol kua yog nquag ua hauj lwm raws li ib tug thib ob refrigerant nyob rau hauv cov nram qab no systems:
Chillers
Cua txias tshuab
Cov chaw cia txias
Nws ua kom yooj yim hloov cov cua sov thaum tiv thaiv cov dej khov hauv cov kav dej.
4. Aircraft De-icing thiab Anti-icing Fluids
Vim nws qhov qis qis qis, nws yog siv hauv kev lag luam aviation rau:
Tshem cov dej khov los ntawm qhov chaw dav hlau
Tiv thaiv kom tsis txhob muaj dej khov rau ntawm lub dav hlau thaum ya tawm hauv huab cua txias
5. Polyester (PET) Ntau lawm
MEG Mono ethylene glycolserves ua cov khoom tseem ceeb hauv kev tsim khoom:
Polyester fibers (siv hauv khaub ncaws thiab textiles)
PET lub raj mis thiab cov khoom ntim
Hauv daim ntawv thov no, nws txoj haujlwm yog tshuaj lom neeg hauv qhov xwm txheej (ua raws li monomer), tsis yog thermal.
6. Industrial De-icing thiab Thermal Storage Systems
Monoethylene Glycol kuj tseem siv rau hauv:
Txoj kev de-icing formulations (nyob rau hauv tej thaj chaw muaj kev lag luam)
Thermal zog cia systems (xws li, hnub ci cua sov, muaj thermal buffering)
Xaus
Ethylene Glycol muaj xws li:
- Kub taw tes ntawm kwv yees li 197.3 degree
- Qhov kub ntawm qhov ntsuas kub ntawm -12.9 ° C
Vim nws muaj peev xwm txo qis qhov khov thiab nce qhov kub hauv dej-raws li kev sib tov, ethylene glycol tau dhau los ua ib qho tseem ceeb tshaj plaws hauv kev lag luam hluav taws xob hloov hluav taws xob thoob ntiaj teb.
