G12 antifreeze yog dab tsi - qhov txawv ntawm G11, G12 +, G13 thiab qhov twg yuav tsum tau sau

Antifreeze yog xav tau kom txias lub cav tsheb. Niaj hnub no, coolants tau muab faib ua 4 hom, txhua qhov sib txawv hauv cov khoom ntxiv thiab qee yam khoom. Tag nrho cov tshuaj tiv thaiv kab mob uas koj pom hauv khw muag khoom yog tsim los ntawm dej thiab ethylene glycol, thiab qhov ntawd yog qhov zoo sib xws. Yog li yuav ua li cas cov coolants txawv ntawm ib leeg, ntxiv rau cov xim thiab cov nqi, xaiv txoj cai antifreeze rau koj lub tsheb, nws puas muaj peev xwm sib tov sib txawv coolants thiab dilute lawv nrog dej - nyeem rau.

Tshuaj tua kab mob yog dab tsi?

Antifreeze yog lub npe nrov rau lub tsheb coolant. Txawm hais tias qhov kev faib tawm, propylene glycol lossis ethylene glycol muaj nyob hauv cov tshuaj tiv thaiv kab mob, thiab nws cov pob khoom ntxiv. 

Ethylene glycol yog tshuaj lom dihydric cawv. Nyob rau hauv nws daim ntawv ntshiab, nws yog ib tug oily kua, nws qab qab zib, nws boiling point yog hais txog 200 degrees, thiab lub freezing point yog -12,5 °, nco ntsoov tias ethylene glycol yog ib tug txaus ntshai tshuaj lom, thiab ib tug tuag koob tshuaj rau ib tug neeg yog 300. grams. Los ntawm txoj kev, cov tshuaj lom yog neutralized nrog ethyl cawv.

Propylene glycol yog ib lo lus tshiab nyob hauv lub ntiaj teb no ntawm coolants. Cov tshuaj tiv thaiv zoo li no yog siv rau hauv txhua lub tsheb niaj hnub no, nrog cov qauv nruj toxicity, ntxiv rau, propylene glycol-based antifreeze muaj lubricating zoo thiab tiv thaiv corrosion. Xws li cawv yog tsim los siv lub teeb theem ntawm roj distillation.

Cov tshuaj tua kab mob qhov twg thiab siv li cas

Antifreeze pom nws daim ntawv thov tsuas yog hauv kev thauj mus los. Feem ntau nws yog siv nyob rau hauv lub cua sov system ntawm cov tsev nyob thiab thaj chaw. Nyob rau hauv peb cov ntaub ntawv, lub luag hauj lwm tseem ceeb ntawm antifreeze yog los tuav lub khiav hauj lwm kub ntawm lub cav nyob rau hauv ib tug muab hom. Coolant yog siv nyob rau hauv lub kaw lub tsho ntawm lub cav thiab kab, nws kuj kis tau los ntawm cov neeg nrog caij compartment, vim hais tias cua sov cua tshuab thaum lub qhov cub qhib. Ntawm qee lub tsheb, muaj cov khoom siv hluav taws xob sib txuas rau kev sib kis tsis siv neeg, qhov chaw tiv thaiv kab mob thiab cov roj sib txuas ua ke nyob rau hauv ib lub tsev, tswj qhov kub ntawm ib leeg.

Yav dhau los, lub zog txias hu ua "Tosol" tau siv hauv tsheb, qhov uas yuav tsum tau ua muaj:

• tswj cov haujlwm ua haujlwm kub;
• lubricating zog.

Nov yog ib qho ua kua dej qis tshaj plaws uas tsis tuaj yeem siv hauv cov tsheb niaj hnub. Tus lej ntawm cov tshuaj tiv thaiv kab mob twb tau tsim rau lawv: G11, G12, G12 + (++) thiab G13.

Antifreeze G11

Antifreeze G11 yog tsim nyob rau hauv lub hauv paus silicate classic, nws muaj cov pob ntawm inorganic ntxiv. Qhov hom coolant no tau siv rau cov tsheb tsim ua ntej 1996 (txawm hais tias kev zam ntawm qee lub tsheb niaj hnub mus txog 2016 ua rau nws muaj peev xwm sau rau G11), hauv CIS nws tau hu ua "Tosol". 

Ua tsaug rau nws cov kua hauv paus, G11 ua cov haujlwm hauv qab no:

• tsim kev tiv thaiv rau saum npoo, tiv thaiv ethylene glycol los ntawm kev puas tsuaj rau lawv;
• ua rau kom qis ntawm kev txhim kho ntawm xeb.

Thaum xaiv cov tshuaj pleev ib ce zoo li no (nws cov xim yog xim xiav thiab ntsuab), them rau ob lub ntsiab lus:

• lub txee lub neej tsis pub tshaj 3 xyoos, tsis hais tus nqi kev mais. Thaum lub sijhawm ua haujlwm, txheej txheej tiv thaiv yuav ua nyias, cov thooj no, tau txais mus rau lub txias, ua rau nws txoj kev hnav nrawm nrawm, nrog rau kev puas tsuaj rau lub taub dej;
• cov txheej tiv thaiv tsis tiv taus kev kub, ntau dua 105 degrees, yog li cov cua sov hloov ntawm G11 yog tsawg.

Txhua qhov tsis zoo tuaj yeem zam tau los ntawm kev hloov pauv tsis tu ncua thiab tiv thaiv lub cav kub dhau. 

Tseem nco ntsoov tias G11 tsis haum rau cov tsheb uas muaj lub tog raj kheej aluminium thaiv thiab lub tshuab hluav taws xob vim tias cov khoom txias tsis muaj peev xwm tiv thaiv lawv nyob hauv siab kub. Ceev faj thaum xaiv cov tuam txhab nyiaj txiag, xws li Euroline lossis Polarnik, nug kom ntsuas qhov ntsuas dej ntsuas, muaj xwm txheej feem ntau tshwm sim thaum cov roj txias lo cim "-40 °" qhov tseeb hloov mus rau-20 ° thiab siab dua.

 Antifreeze G12, G12 + thiab G12 ++

G12 hom tshuaj tiv thaiv kab mob yog liab lossis liab. Nws tsis muaj silicates nyob rau hauv nws muaj pes tsawg leeg, nws yog raws li carboxylate tebchaw thiab ethylene glycol. Qhov nruab nrab kev pab cuam lub neej ntawm xws li ib tug coolant yog 4-5 xyoo. Ua tsaug rau kev xaiv cov khoom ntxiv kom zoo, cov khoom tiv thaiv corrosion ua haujlwm xaiv - cov yeeb yaj kiab tsuas yog tsim nyob rau hauv qhov chaw puas los ntawm xeb. G12 antifreeze yog siv nyob rau hauv high-speed engine nrog kev khiav hauj lwm kub ntawm 90-110 degrees.

G12 tsuas muaj ib qho tsis zoo: kev tiv thaiv xeb tshwm sim tsuas yog nyob ntawm qhov tsis muaj xeb.

Feem ntau feem ntau G12 raug muag raws li cov mloog zoo nrog "-78 °" lossis "-80 °", yog li koj yuav tsum xam tus nqi ntawm cov coolant hauv lub system thiab zom nws nrog dej distilled. Qhov sib piv ntawm cov dej mus rau tshuaj tua kab mob yuav qhia ntawm daim ntawv lo.

Rau G12 + antifreeze: nws tsis txawv ntau ntawm nws tus neeg ua ntej, xim yog xim liab, qhov kev txhim kho tau ua kom muaj kev nyab xeeb thiab zoo dua hauv ib puag ncig. Cov nkauj muaj cov tshuaj tiv thaiv kev tiv thaiv, ua hauj lwm pointwise.

G12 ++: feem ntau ua xaum xim, ib qho hloov kho ntawm carboxylated coolants. Lobride tshuaj tua kab mob sib txawv txawv ntawm G12 thiab G12 + nyob rau hauv muaj cov silicate ntxiv, ua tsaug uas cov khoom tiv thaiv ua haujlwm ua hauj lwm pointwise thiab tiv thaiv kom tsis txhob muaj cov xeb.

Antifreeze G13

Cov chav kawm tshiab ntawm kev tua tshuaj muaj nyob hauv ntshav. Kev ua haujlwm ua ke ua ke muaj qhov sib xyaw zoo sib xws, tab sis muaj kev pom zoo ntau ntawm silicate thiab organic. Nws tseem muaj cov khoom tiv thaiv zoo tuaj. Nws raug nquahu kom hloov txhua 5 xyoos.

Antifreeze G11, G12 thiab G13 - dab tsi yog qhov txawv?

Cov lus nug feem ntau tshwm sim - nws puas tuaj yeem sib tov sib txawv antifreezes? Ua li no, koj yuav tsum delve rau hauv cov yam ntxwv ntawm txhua lub coolant kom nkag siab txog compatibility.

Qhov sib txawv loj ntawm G11 thiab G12 tsis yog xim, tab sis cov ntsiab lus tseem ceeb: tus qub muaj ib qho inorganic / ethylene glycol puag. Koj tuaj yeem sib tov nws nrog cov tshuaj tiv thaiv kab mob, qhov tseem ceeb yog tias muaj chav kawm sib raug zoo - G11.

Qhov sib txawv ntawm G12 thiab G13 yog tias zaum ob muaj propylene glycol puag, thiab chav kawm kev nyab xeeb ib puag ncig yog ob peb zaug ntau dua.

Rau kev sib tov txias:

• G11 tsis sib xyaw nrog G12, koj tsuas ntxiv tau G12 + thiab G13;
• G12 cuam tshuam nrog G12 +.

Cov Lus Nug thiab Cov Lus Teb:

Antifreeze siv rau dab tsi? Nws yog cov kua dej ua haujlwm ntawm lub tsheb cav cua txias. Nws muaj qhov kub kub kub thiab muaj cov dej thiab cov khoom ntxiv uas lubricate lub twj tso kua mis thiab lwm yam CO.

Vim li cas thiaj hu ua antifreeze? Anti (tawm tsam) Freeze (freeze). Qhov no feem ntau yog lub npe rau tag nrho cov tshuaj tiv thaiv khov uas siv hauv tsheb. Tsis zoo li antifreeze, antifreeze muaj qis crystallization kub.

Cov tshuaj tiv thaiv kab mob dab tsi muaj? Ethylene glycol, carboxylate ethylene glycol, hybrid ethylene glycol, lobrid ethylene glycol, propylene glycol. Lawv kuj txawv ntawm cov xim: liab, xiav, ntsuab.
