Antifreeze yog kua uas tsis khov rau thaum muaj qhov kub qis. Nws yog dav siv los txias txias sab hauv cov tshuab txuas. Thiab hauv kev aviation nws yog siv los ua cov kua dej ua ke, hauv kev lag luam nws yog qhov tsim nyog rau kev teeb tsa ua haujlwm ntawm qhov kub tsawg.
Cov Lus Qhia

Muaj ntau hom kev tua tshuaj tiv thaiv. Ntsev yog tsim ntawm lub hauv paus ntawm hydrochloric acid los yog sodium chloride. Xws li lub taub yees yog pheej yig, tab sis nws muaj ib qho tseem ceeb drawback, uas negates tag nrho nws cov zoo. Lub tshuab radiator yuav tsum tau ua los ntawm nyiaj, kub lossis platinum kom thiaj li tau muab cov tshuaj brine nchuav rau hauv lub tshuab cua txias. Lwm yam khoom siv tsis tiv taus xeb. Yog tias koj nchuav ntsev tshuaj tua kab rau hauv lub tshuab ntsuas hluav taws xob tas li, ntsev yuav txiav txim rau ntawm phab ntsa. Qhov no yuav corrode sai dua li ib txwm muaj kua aqueous.

Glycerine antifreezes tau siv rau hauv cov tsheb yav dhau los. Lawv tau nrov hauv 20s. XX caug xyoo. Lawv tau nyeem heev thiab yog li ntawd muaj cov khoom ntws tsis zoo. Qhov kev noj haus ntawm cov tshuaj tua kab mob zoo heev, thiab ntau lub zog tau siv rau "tso" lub zog txias. Niaj hnub no cov tshuaj tua kab mob yog siv rau hauv qhov cua sov.
Kauj ruam 3
Cov tshuaj tiv thaiv kev ua haujlwm rau cov cua sov yuav tsum tau hais tawm kom sib cais. Nws yog qhov tseeb dua yog hu ua kua dej kub hloov dej. Automotive ethylene glycol tshuaj tua tsis siv tsis yog siv rau hauv cov cua sov. Nws yog txhua yam hais txog kev mob lom ntawm ethylene glycols.
Kauj ruam 4
Cov tub yees siv hauv cov tshuab ua cua sov yog tsim tawm ntawm cov khoom siv propylene glycol lossis glycerin. Cov tshuaj yeeb dej caw no muaj kev nyab xeeb dua thiab siv rau hauv cov chaw ua tshuaj thiab tshuaj pleev ib ce. Tsis tas li, cov organic no tau siv rau hauv cov tshuab cua txias thiab tshuab cua txias ntawm txhua hom kev lag luam.
Kauj ruam 5
Glycolic cov tshuaj tua kabmob muaj ntau heev. Hauv tebchaws Russia, feem ntau cov tshuaj tiv thaiv tsheb yog tsim los ntawm monoethylene glycol, feem ntau tsis tshua muaj triethylene glycol lossis diethylene glycol yog siv rau lawv ntau lawm.
Kauj Ruam 6
Cov cuab yeej tseem ceeb ntawm cov kua yog tias lawv muaj peev xwm qis qis kom khov ntawm lawv cov kev daws teeb meem aqueous. Kev daws daws khov ntawm qhov kub thiab txias txij li 0 txog -68 °, nws tag nrho yog nyob ntawm qhov feem ntawm ethylene glycol thiab dej. Kev siv cov tshuaj tiv thaiv corrosion thiab lwm yam tshuaj ntxiv tsis tsuas yog txo cov phom sij ua rau lub zog txias, tab sis kuj nce qhov kub ntxhov ntawm cov kua dej.
Kauj Ruam 7
Cov tshuaj tiv thaiv kev quav cawv yog siv rau cov khaub hlab ua kom dab, pneumatic nres. Lawv tsis siv hauv xyaw, vim tias cawv muaj qhov zoo nplaim taws.
