Cov tshuaj tua kab tseem ceeb yog qhov tseem ceeb ntawm cov tshuab txias, tiv thaiv tus coolant los ntawm khov rau hauv txias thiab npau npau hla hauv cov xwm txheej kub. Ob qho tib si cov tshuaj siv hauv cov tshuaj pleev cov tshuaj pleev cov tshuaj yog propylene glycol (pg) thiab mono ethylene glycol (meg). Kab lus no yuav muab ob yam tshuaj piv tau ob yam tshuaj no nyob rau hauv cov ntsiab lus ntawm lawv qhov sib txawv ntawm cov tshuaj tiv thaiv.
Dab tsi yog antifreeze yog dab tsi?
Feem ntau cov ensifrowed formulations yog kev sib xyaw ntawm cov dej huv siab (xws li dej noo) thiab ethylene glycol. Multi-hlau thiab ntau tus ua haujlwm Inibitors kuj ntxiv rau kev tiv thaiv kev xeb hauv kev txhim kho sab hauv, ntsuas kev ua si ob lub luag hauj lwm tseem ceeb hauv kev tiv thaiv cua sov thiab cua txias. Firstly, nws lowers qhov khov taw tes ntawm cov dej, tso cai rau cov tshuab los ntws dawb thiab zam cov pos tsuag txias ntev dua thaum lub caij ntuj sov. Thib ob, nws tsa cov dej npau npau los tiv thaiv ib qho teeb meem cua sov tshaj plaws.
Dab tsi yog qhov sib txawv ntawm propylene glycol thiab ethylene glycol?
Propylene Glycol (Pg)
Propylene Glycol muaj cov tshuaj noj C3H802. Nws kuj yog ib yam kua tsis muaj kob, tsis muaj ntxhiab. Nws muaj cov khoom cua sov hauv qhov kub thiab txias ntawm {2}} degree F. PG yog me ntsis mislible hauv dej, ethanol, diethil ether, acetone thiab chloroform.
PG muaj cov peev xwm hloov cua sov, tab sis yog tsawg dua tsawg dua MEG; Txawm li cas los xij, nws tseem txaus kom qis dua qhov taw tes khov thiab tsa lub boiling taw tes, muab kev tiv thaiv kom khov. ,

Ethylene glycol (meg)
Ethylene glycol muaj tshuaj lom neeg c2h602. Nws yog ib qho tsis muaj kob, nil, kua paug. Nws muaj ob pawg hydroxyl - huag) uas muab nws siab thermal stability. Glycol muaj cov kub ua hluav taws kub zoo thiab qis viscosity, cov khoom uas yog qhov tseem ceeb rau kev ua kom muaj dej txias hauv cov tshuab txias.
Glycol yog tsis tshua muaj txiaj ntsig nyob rau hauv tshav kub hloov. Nws siv tau zoo thiab dissipates kub tsim los ntawm lub cav. Cov cuab yeej no pab tiv thaiv kev kub ntxhov thiab ua kom cov lag luam du ntawm lub tshuab cua txias. Nws yog dav siv nyob rau hauv kev lag luam hauv lub tshuab thiab muaj cov tshuab txias.
Meg tuaj yeem muab cov taw tes khov rau cov khoom sib xyaw txias. Pab kom lub tshuab txias kom txias kom ua haujlwm nyob rau hauv ib puag ncig txias heev.
Kev Cuam Tshuam Toxicity
Monoethylene Glycol yog lom rau tib neeg thiab ua rau muaj teeb meem ntawm lub cev, yog li ntawd, ethylene ghlum yuav tsum tsis txhob siv rau hauv cov ntawv thov uas nws yuav paug cov dej haus. MEG yuav tsum tsis txhob siv rau hauv cov cua sov lossis cua txias hauv cov khoom lag luam ua khoom noj lossis lwm cov khoom lag luam tsim khoom lag luam.
Propylene glycol muaj ho qis toxicity. Teb Chaws Asmeskas Khoom Noj thiab Tshuaj Yeeb (FDA) txiav txim siab nws yuav feem ntau rau kev siv zaub mov thiab cov tshuaj pleev ib ce. Thaum noj mov, nws yog excreted nyob rau hauv cov zis lossis hloov dua siab tshiab rau lactic acid thiab lwm cov metabolites ib txwm muaj. Propylene Glycol kuj tseem muaj ntau dua biodegradable thiab yog li ntawd muaj qhov qis dua ib puag ncig ib puag ncig me pos.
Gneebio khoom siv ob qho tib siEthylene glycolthiabPropylene GlycolCov. Yog xav paub ntxiv txog kev xaiv cov glycol rau koj daim ntawv thov lossis tsimThov hu rau peb.
