Kuv puas tuaj yeem sib xyaw G11 thiab G12 cov tshuaj tua kab mob?

Antifreeze G11 thiab G12. Qhov txawv yog dab tsi?

Feem ntau ntawm cov coolants (coolants) rau pej xeem tsheb yog tsim los ntawm dihydric alcohols, ethylene los yog propylene glycols, thiab dej distilled. Dej thiab cawv muaj ntau dua 90% ntawm tag nrho cov tshuaj tiv thaiv. Ntxiv mus, qhov proportions ntawm ob lub Cheebtsam no yuav txawv nyob ntawm seb qhov yuav tsum tau txias kub ntawm coolant. Tus so ntawm antifreeze yog nyob los ntawm additives.

G11 antifreeze, zoo li nws yuav luag tag nrho domestic counterpart Tosol, kuj muaj ethylene glycol thiab dej. Cov tshuaj tiv thaiv kab mob no siv cov tshuaj inorganic, ntau yam phosphates, borates, silicates thiab lwm yam khoom siv ntxiv. Inorganic compounds ua ntej ntawm qhov nkhaus: li ntawm ob peb teev tom qab sau rau hauv lub kaw lus, lawv tsim cov yeeb yaj kiab tiv thaiv ntawm phab ntsa ntawm tag nrho cov cua txias. Cov yeeb yaj kiab theem kev txhoj puab heev ntawm cawv thiab dej. Txawm li cas los xij, vim yog cov txheej txheem ntxiv ntawm lub tsho txias thiab lub coolant, qhov kev tshem tawm cov cua sov txo qis. Tsis tas li ntawd, lub neej kev pab cuam ntawm chav kawm G11 antifreezes nrog inorganic additives yog luv luv thiab nruab nrab 3 xyoo rau cov khoom zoo.

G12 antifreeze kuj tsim los ntawm kev sib xyaw ntawm dej thiab ethylene glycol. Txawm li cas los xij, cov additives hauv nws yog cov organic. Namely, lub ntsiab tiv thaiv tiv thaiv ethylene glycol aggression nyob rau hauv G12 antifreeze yog carboxylic acid. Organic carboxylate additives tsis tsim ib homogeneous zaj duab xis, yog li ntawd qhov kev siv ntawm tshav kub tshem tawm tsis poob. Carboxylate compounds ua pointwise, tshwj xeeb tshaj yog nyob rau ntawm qhov chaw corrosion tom qab lawv cov tsos. Qhov no me ntsis txo cov khoom tiv thaiv, tab sis tsis cuam tshuam rau thermodynamic zog ntawm cov kua. Nyob rau tib lub sijhawm, cov tshuaj tiv thaiv zoo li no ua haujlwm rau li 5 xyoos.

G12 + thiab G12++ antifreezes muaj cov organic thiab inorganic additives. Nyob rau tib lub sij hawm, muaj ob peb inorganic additives uas tsim ib tug tshav kub-insulating txheej nyob rau hauv cov coolants. Yog li ntawd, G12 + thiab G12 ++ antifreezes xyaum tsis cuam tshuam nrog kev tshem tawm cua sov thiab tib lub sijhawm muaj ob qib kev tiv thaiv.

G11 thiab G12 puas tuaj yeem sib xyaw ua ke?

Koj tuaj yeem sib xyaw G11 thiab G12 antifreezes hauv peb kis.

1. Hloov chaw ntawm G11 antifreeze pom zoo, koj tuaj yeem sau dawb hauv G12 ++ chav kawm txias txias, nrog rau sib tov ob qhov dej txias hauv txhua qhov sib npaug. Antifreeze G12 ++ yog universal, thiab yog hais tias nws hloov hom kev ua hauj lwm ntawm lub txias system, ces nws yog insignificant. Nyob rau tib lub sijhawm, cov khoom tiv thaiv ntawm chav kawm ntawm cov coolant no siab, thiab cov khoom siv ntxiv ntxiv yuav ntseeg tau los tiv thaiv txhua qhov system los ntawm corrosion.
2. Es tsis txhob G11 antifreeze, koj tuaj yeem sau rau hauv G12 + rau tib lub laj thawj uas tau piav qhia hauv thawj kab lus. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv no, tej zaum yuav muaj ib tug me ntsis txo nyob rau hauv cov kev pab cuam ntawm ib tug neeg lub ntsiab ntawm lub cav txias system.
3. Koj tuaj yeem ruaj ntseg ntxiv rau ib leeg hauv qhov me me, txog li 10%, antifreeze hom G11 thiab G12 (suav nrog tag nrho lawv cov kev hloov kho). Qhov tseeb yog tias cov additives ntawm cov coolants no tsis tawg thiab tsis ua kom dej nag thaum muaj kev sib cuam tshuam, tab sis tsuas yog nyob rau hauv cov xwm txheej uas cov kua dej yog thawj zaug zoo thiab ua raws li cov qauv.

Nws raug tso cai, tab sis tsis pom zoo, sau rau hauv chav kawm G11 coolant es tsis txhob G12 antifreeze. Qhov tsis muaj inorganic additives tuaj yeem txo qhov kev tiv thaiv ntawm cov roj hmab thiab cov khoom siv hlau thiab txo lub neej ntawm tus kheej cov ntsiab lus ntawm lub cev.

Nws yog tsis yooj yim sua kom sau nyob rau hauv coolant chav G12 ua ke nrog G11 antifreeze yuav tsum tau. Qhov no yuav cuam tshuam tsis zoo rau qhov kev siv ntawm cov cua sov dissipation thiab tuaj yeem ua rau lub cev muaj zog.
