Ethylene glycol khov taw tes ntsuas

Ethylene glycol yog lub ntsiab tivthaiv ntawm cov tshuaj tua kab mob, suav nyiaj rau txog 45% ntawm cov tshuaj antifroze. Cov tshuaj antifreas, cov khoom siv tsis tau nrog dej nyob hauv qee qhov kev faib ua feem raws li qhov kub ntawm txhua qhov chaw kom tswj tau qhov chaw khov nyob rau hauv ib qho kev cia siab. Cov tshuaj tiv thaiv zoo siv tau cov cawv muaj ntau yam organic.
Txij li thaum xyoo 1950, yuav luag txhua lub tebchaws tau txais kev ethylene glycolol raws li cov tshuaj tiv thaiv. Ethylene glycol yog ib qho tsis muaj xim, pob tshab, qab zib me ntsis thiab hygroscopic viscous kua uas tuaj yeem yaj nyob hauv ib qho kev faib ua feem. Lub ntsiab lus khov yog qhov sib txawv thaum lub concentration ntawm ethylene glycol yog txawv. Cov kev taw qhia khov ntawm ethylene glycol - dej antifroze tsis yog linearly cuam tshuam nrog huab hwm coj ntawm ethylene glycol. Lub ntsiab lus khov ntawm nws cov kua aqueous tsis tau txo qis nrog kev nce siab. Thaum cov concentration ntau dua 70%, tso rau taw tes nce siab. Hauv cov txheej txheem npaj, kev xaiv tsim nyog yuav tsum tau ua raws li cov haujlwm tiag tiag kom ua tiav cov kev xav tau ntawm cov tshuaj tiv thaiv thiab kev lag luam. Hauv Jiangnan, Suav teb, ib feem ntawm 40% Glycol Pawg feem ntau siv, thaum muaj kev sib txawv ntawm 50% glycol pawg feem yog qhov tsim nyog dua.
