Kuv puas tuaj yeem sib xyaw G12 thiab G13 cov tshuaj tua kab mob?

Antifreeze G12 thiab G13. Qhov txawv yog dab tsi?

Feem ntau ntawm cov kua uas npaj rau siv nyob rau hauv niaj hnub tsheb txias tshuab muaj peb yam:

• yooj yim dihydric cawv (ethylene glycol lossis propylene glycol);
• distilled dej;
• pob ntawm additives (anti-corrosion, tiv thaiv, anti-foam, thiab lwm yam).

Dej thiab dej cawv dihydric ua rau ntau tshaj 85% ntawm tag nrho cov coolant ntim. Qhov seem 15% yog los ntawm additives.

Class G12 antifreezes, raws li cov kev faib tawm, muaj peb subclasses: G12, G12 + thiab G12 ++. Lub hauv paus rau txhua chav G12 kua yog tib yam: ethylene glycol thiab dej distilled. Qhov sib txawv yog nyob rau hauv cov additives.

G12 antifreeze muaj carboxylate (organic) additives. Lawv ua haujlwm nkaus xwb los tiv thaiv foci ntawm corrosion thiab tsis tsim cov yeeb yaj kiab tiv thaiv txuas ntxiv, xws li hauv chav kawm G11 coolants (los yog hauv tsev antifreeze). G12+ thiab G12++ kua dej muaj ntau yam. Lawv muaj ob qho tib si organic thiab inorganic additives muaj peev xwm tsim ib tug tiv thaiv zaj duab xis ntawm qhov chaw ntawm lub cua txias, tab sis ntau thinner dua nyob rau hauv cov chav kawm ntawv G11 coolants.

G13 antifreeze muaj lub hauv paus ntawm propylene glycol thiab dej distilled. Ntawd yog, cawv tau hloov pauv, uas ua kom muaj kev tiv thaiv ntawm cov muaj pes tsawg leeg kom khov. Propylene glycol tsis muaj tshuaj lom thiab tsis tshua muaj tshuaj lom ntau dua li ethylene glycol. Txawm li cas los xij, tus nqi ntawm nws cov khoom siv ntau zaus ntau dua li ntawm ethylene glycol. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, hais txog kev ua hauj lwm nyob rau hauv lub tsheb lub coolant system, qhov sib txawv ntawm cov cawv yog me me. Cov khoom ntxiv hauv chav kawm G13 antifreezes tau ua ke, zoo ib yam thiab muaj nuj nqis rau G12 ++ coolants.

G12 thiab G13 tuaj yeem ua kom tsis muaj zog tuaj yeem sib xyaw?

Tsis muaj lus teb meej rau cov lus nug ntawm seb puas tuaj yeem sib xyaw cov chav kawm antifreeze G12 thiab G13. Ntau yam nyob ntawm tus tsim ntawm lub tshuab cua txias thiab cov proportions ntawm cov kua sib tov. Xav txog ntau qhov xwm txheej ntawm kev sib xyaw G12 thiab G13 antifreezes.

1. Nyob rau hauv ib qho system uas G12 antifreeze los yog ib qho ntawm nws lwm subclasses tau sau rau hauv, G20 antifreeze yog ntxiv rau qhov tseem ceeb (ntau tshaj 13%). Xws li kev sib xyaw yog tsim nyog, tab sis tsis pom zoo. Thaum sib xyaw, cov cawv cawv yuav tsis cuam tshuam nrog ib leeg. Cov kua uas tau los ntawm kev sib xyaw tshuaj tiv thaiv kab mob G12 thiab G13 yuav hloov me ntsis ntawm qhov chaw khov, tab sis qhov no yuav hloov me ntsis. Tab sis cov additives tuaj yeem cuam tshuam. Cov neeg nyiam kev sim hauv qhov no tau xaus nrog cov txiaj ntsig sib txawv, tsis paub tseeb. Qee zaum, cov nag lossis daus tsis tshwm sim txawm tias tom qab lub sijhawm ntev thiab tom qab cua sov. Hauv lwm qhov xwm txheej, thaum siv cov kua dej sib txawv los ntawm cov tuam txhab sib txawv, qhov pom ntawm qhov sib txawv tshwm sim hauv qhov sib xyaw ua ke.

2. Hauv ib qho system tsim los rau G13 antifreeze, ib qho tseem ceeb (ntau tshaj 20% ntawm tag nrho cov ntim) yog ntxiv rau hauv chav kawm G12 coolant. Qhov no ua tsis tau. Hauv txoj kev xav, cov tshuab tsim los rau G13 antifreeze tsis tas yuav ua los ntawm cov khoom siv nrog kev tiv thaiv kev ua phem rau tshuaj lom neeg, raws li xav tau rau cov tshuab rau G12 antifreeze. Propylene glycol muaj cov tshuaj lom neeg tsawg. Thiab yog tias lub tuam txhab tsim tsheb tau siv qhov zoo ntawm lub sijhawm no thiab ua cov khoom siv los ntawm cov khoom siv tsis yog ib txwm siv, ces ethylene glycol tuaj yeem ua kom puas tsuaj sai sai rau cov khoom uas tsis ruaj khov rau nws cov teebmeem.
3. Ib qho me me ntawm G12 antifreeze yog ntxiv rau lub kaw lus uas muaj G13 antifreeze (los yog rov ua dua). Qhov no tsis pom zoo, tab sis nws muaj peev xwm ua tau thaum tsis muaj lwm txoj hauv kev tawm. Yuav tsis muaj qhov tshwm sim tseem ceeb, thiab nyob rau hauv txhua rooj plaub, qhov no yog qhov kev xaiv ntau dua li kev tsav tsheb nrog qhov tsis muaj cov dej txias hauv qhov system.

Koj tuaj yeem hloov G12 antifreeze tag nrho nrog G13. Tab sis ua ntej ntawd, nws yog qhov zoo dua los yaug qhov cua txias. Hloov G13, koj tsis tuaj yeem sau G12.

Antifreeze G13.. G12 Mix? 🙂
