CAS 107-21-1 Ethylene glycol (EG) yog lub hauv paus kua dej rau lub tsheb txias vim tias nws tuaj yeem txo qhov dej khov ntawm dej thiab nce nws qhov kub. Thaum sib tov nrog dej hauv qhov sib piv 1: 1 (50/50), qhov ua kom txias txias ua rau lub cav kom tiv taus qhov kub thiab txias, kom ntseeg tau tias nws tseem tsis khov thaum lub caij ntuj no txias thiab tsis kub thaum lub caij ntuj sov kub.
Niaj hnub nimno combustion engines ua kom muaj cua sov loj heev thaum lub sijhawm ua haujlwm. Yog tias tsis muaj qhov ua kom txias txias, lub cav yuav ua rau kub dhau sai, ua rau thermal stress, lubricant breakdown, tivthaiv deformation, thiab tej zaum yuav muaj kev puas tsuaj rau txhua yam tsis ua hauj lwm.
Dej tsis tuaj yeem muab kev tiv thaiv txaus rau lub tsheb txias vim tias, nyob rau hauv cov txheej txheem atmospheric siab, dej muaj qhov khov ntawm 0℃thiab qhov kub ntawm tsuas yog 100 degree. Ethylene glycol ua tau zoo kov yeej cov kev txwv no los ntawm kev hloov kho lub cev thermodynamic zog ntawm dej; concurrently, nws muab kev tiv thaiv corrosion, yog li txhim kho lub durability ntawm cov cua txias system.
Vim li cas Lub Tsheb Cav Yuav Tsum Tau Coolant?
Thaum lub sij hawm ua hauj lwm, lub combustion engines tsim ib tug tseem ceeb npaum li cas ntawm cov cua sov tshaj; lawv qhov kev khiav hauj lwm kub ib txwm nyob nruab nrab ntawm 85℃thiab 105 degree, txawm hais tias qhov kub thiab txias tuaj yeem nce siab dua nyob rau hauv cov khoom hnyav lossis nyob rau hauv qhov kub ntawm - qhov kub thiab txias. Yog tias tsis muaj cov dej txias zoo los tswj cov cua sov no, lub cav ntsib qhov tshwm sim loj heev, xws li kev nthuav dav hlau ntau dhau, kev ua haujlwm tsis zoo ntawm cov roj nplua nyeem, txo qis kev sib xyaw ua haujlwm, thiab txawm tias cov khoom deformation lossis lub cav nres. Lub luag haujlwm ntawm lub cav coolant yog nqus, thauj, thiab dissipate qhov kub tshaj no -pab los ntawm lub radiator- yog li xyuas kom meej tias lub cav tseem nyob rau hauv ib qho chaw ruaj khov thiab muaj kev nyab xeeb ua haujlwm.
Yuav ua li cas Ethylene glycol kua txhim kho Coolant Performance
Ethylene glycol optimizes coolant zog ntawm molecular kev sib cuam tshuam thiab colligative zog. Nws txo qis qhov chaw khov, nce qhov kub thiab txias, stabilizes tshav kub hloov thiab boosts corrosion kuj.
1. Kev tiv thaiv khov
EG cuam tshuam cov dej khov siv lead ua tom qab sib xyaw nrog dej. Raws li lub hauv paus ntsiab lus ntawm kev nyuaj siab qhov chaw khov, nws ua tau zoo txo qhov txias txias txias txias.
2. Ethylene glycol tsa lub Boiling Point
Lub cav ua haujlwm kub feem ntau mus txog lossis tshaj qhov kub ntawm cov dej ntshiab, uas yooj yim vaporizes thiab ua rau cov hnab tshos ua kom tsis muaj cua txias.
Ethylene glycol kua nce qhov kub ntawm qhov sib xyaw ua kom txias tom qab qhov ntsuas kub kub nce siab. Ib qho 50% EG- cov kua dej hauv qab siab tuaj yeem tiv taus qhov kub thiab txias tshaj 120℃. Nws zoo tiv thaiv cov dej txias dhau, vapor lock, cavitation thiab ib nrab overheating.
3. EG Txhawb Kev Hloov Cov Kub Kub Zoo
Cov dej ntshiab muab cov cua kub hloov pauv zoo dua, thaum EG Ethylene glycol muaj kev txhim khu kev qha los tiv thaiv - khov thiab tiv thaiv - muaj peev xwm boiling. Lawv qhov sib xyaw ua kom zoo tshaj qhov sib npaug ntawm kev sib pauv cua sov, qhov kub thiab txias thiab kev ua haujlwm ruaj khov.
4. Anti-Kev tiv thaiv corrosion
Ethylene glycol mix coolant yog txuam nrog corrosion inhibitors. Cov additives no tiv thaiv aluminium radiators, hlau cav blocks, tooj liab alloy qhov chaw, steel pipelines thiab vuam pob qij txha los ntawm electrochemical corrosion, ncua kev pab cuam lub neej ntawm tag nrho cov txias system.
5. EG muab cov roj twj tso kua mis
EG-raws li coolant lubricates dej twj tso kua mis thiab cov khoom txav tau. Nws txiav kev sib txhuam thiab kev sib tsoo, ua kom tsis txhob muaj cov twj tso kua mis thaum ntxov, qhov zoo dua cov dej ntshiab tsis tuaj yeem muab.
