Kuv puas tuaj yeem sib xyaw G12 thiab G12 + antifreeze?
Txheem
Antifreeze nrog G12 + thiab G12. Qhov txawv yog dab tsi?
Tag nrho cov coolants sau npe raws li G12 (nrog rau kev hloov kho G12 + thiab G12 ++) muaj ethylene glycol, dej distilled thiab ib pob ntxiv. Dej thiab dihydric cawv ethylene glycol yog cov khoom tseem ceeb ntawm yuav luag tag nrho cov tshuaj tua kab mob. Ntxiv mus, cov proportions ntawm cov ntsiab lus tseem ceeb rau antifreezes ntawm ntau hom, tab sis nrog tib lub freezing kub, xyaum tsis hloov.
Qhov sib txawv tseem ceeb ntawm G12 + thiab G12 antifreezes yog qhov tseeb hauv cov khoom ntxiv.
G12 antifreeze hloov G11 cov khoom, uas yog outdated lub sij hawm ntawd (los yog Tosol, yog hais tias peb xav txog domestic coolants). Inorganic additives nyob rau hauv antifreezes ntawm outdated coolants, uas tsim ib tug nruam tiv thaiv zaj duab xis nyob rau hauv lub puab nto ntawm lub txias system, muaj ib tug tseem ceeb drawback: lawv txo cov kev siv ntawm tshav kub hloov. Nyob rau hauv tej yam kev mob uas lub load nyob rau hauv lub combustion engine nce, yuav tsum tau ib tug tshiab, ntau npaum tov, txij li thaum tus txheej txheem antifreezes yuav hardly tiv nrog lub txias ntawm "kub" motors.
Inorganic additives hauv G12 antifreeze tau hloov nrog cov organic, carboxylate sawv daws yuav. Cov khoom siv no tsis tau ntim cov kav dej, lub tshuab hluav taws xob radiator honeycombs thiab lub tsho txias nrog cov txheej txheem cua sov. Carboxylate additives tsim ib zaj duab xis tiv thaiv tsuas yog nyob rau hauv qhov txhab, tiv thaiv lawv txoj kev loj hlob. Vim li no, qhov kev siv ntawm cov cua sov hloov pauv tseem siab, tab sis feem ntau, kev tiv thaiv tag nrho ntawm cov cua txias los ntawm cov tshuaj yeeb dej caw, ethylene glycol, poob.
Qhov kev txiav txim siab no tsis haum rau qee tus neeg tsim tsheb. Tseeb, nyob rau hauv cov ntaub ntawv ntawm G12 antifreeze, nws yog tsim nyog los muab ib tug ntau dua margin ntawm kev nyab xeeb rau lub txias system los yog muab tso rau nrog nws cov kev pab poob.
Yog li ntawd, tsis ntev tom qab tso tawm G12 antifreeze, ib qho khoom tshiab nkag mus rau hauv kev lag luam: G12 +. Nyob rau hauv no coolant, ntxiv rau carboxylate additives, inorganic additives tau ntxiv nyob rau hauv me me. Lawv tsim ib tug nyias txheej tiv thaiv nyob rau hauv tag nrho cov saum npoo ntawm lub txias system, tab sis xyaum tsis txo cov kev siv ntawm tshav kub hloov lwm lub tsev. Thiab nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj rau zaj duab xis no, carboxylate compounds tuaj rau hauv kev ua si thiab kho qhov chaw puas.
G12 + thiab G12 antifreezes puas tuaj yeem sib xyaw?
Kev sib xyaw tshuaj tiv thaiv kab mob feem ntau suav nrog kev ntxiv ib hom coolant rau lwm tus. Nrog rau kev hloov ua tiav, feem ntau tsis muaj leej twg yog cov khoom seem ntawm ntau lub kaus poom. Yog li ntawd, peb xav txog ob qhov xwm txheej ntawm kev sib xyaw.
- Lub tank pib muaj G12 antifreeze, thiab koj yuav tsum tau ntxiv G12 +. Nyob rau hauv cov ntaub ntawv no, koj yuav xyuam xim sib tov. Chav G12+ coolants yog, hauv paus ntsiab lus, universal thiab tuaj yeem sib xyaw nrog lwm yam tshuaj tiv thaiv kab mob (nrog tsis tshua muaj kev zam). Kev khiav hauj lwm kub ntawm lub cav yuav tsis nce, tus nqi ntawm kev puas tsuaj ntawm cov ntsiab lus system yuav tsis nce. Additives yuav tsis cuam tshuam nrog ib leeg nyob rau hauv ib txoj kev, lawv yuav tsis precipitate. Tsis tas li ntawd, kev pab cuam lub neej ntawm cov tshuaj tiv thaiv kab mob yuav nyob zoo ib yam, vim tias ob qho tib si ntawm cov khoom no, raws li tus qauv, muaj lub sijhawm hloov pauv ntawm 5 xyoos.
- Nws yog Ameslikas nyob rau hauv G12 + system, thiab koj yuav tsum tau sau rau hauv G12. Qhov kev hloov pauv no kuj raug tso cai. Qhov tshwm sim nkaus xwb uas tuaj yeem tshwm sim yog kev tiv thaiv me ntsis ntawm qhov chaw sab hauv ntawm lub cev vim tsis muaj cov khoom siv tsis zoo hauv cov khoom siv ntxiv. Cov kev hloov tsis zoo no yuav muaj tsawg heev uas lawv tuaj yeem tsis quav ntsej.
Automakers qee zaum sau tias nws tsis tuaj yeem ntxiv G12 rau G12 +. Txawm li cas los xij, qhov no yog qhov kev ntsuas ntau dhau ntawm kev pov hwm tshaj li qhov xav tau tsim nyog. Yog tias koj xav tau rov ua dua lub kaw lus, tab sis tsis muaj lwm txoj hauv kev, xav kom sib tov txhua chav G12 antifreeze, tsis hais cov chaw tsim khoom thiab subclass. Tab sis nyob rau lub sijhawm, tom qab xws li kev sib tov, nws yog qhov zoo dua los hloov kho cov tshuaj tiv thaiv kab mob hauv lub cev thiab sau cov dej txias uas yuav tsum tau ua los ntawm cov kev cai.
