Antifreeze G11, G12 thiab G13
Cov kua siv los ua kom txias lub cav tsheb yog hu ua antifreezes. Tag nrho cov ntawm lawv muaj qhov chaw txias txias heev thiab siv rau hauv lub tsheb cua txias. Nws yuav tsum tau borne nyob rau hauv lub siab hais tias lawv yog cov zoo sib xws nyob rau hauv muaj pes tsawg leeg, tab sis muaj ib co nuances nyob rau hauv lub tshuab ntawm lawv tsim, txawv teb chaws tau tsim lawv tus kheej specifications rau coolants. Qhov nrov tshaj plaws antifreezes ntawm Volkswagen G11, G12 thiab G13 pib txhawj xeeb. Peb yuav tshuaj xyuas kom ntxaws ntxiv txog cov yam ntxwv thiab kev siv cov kua dej no thiab lawv cov kev siv peev txheej txhawm rau tiv thaiv lub tsheb kom ntau li ntau tau los ntawm qhov tsis tau pom dua.
Hom antifreeze qeb G
Tag nrho cov tshuaj tua kab mob muaj kwv yees li 90% ethylene glycol lossis propylene glycol. Lawv kuj ntxiv txog 7% additives thiab tshuaj nrog anti-foam thiab anti-cavitation zog. Additives muaj cov tshuaj sib txawv kiag li. Qee qhov yog tsim los ntawm cov ntsev ntawm inorganic acids, xws li silicates, nitrites, phosphates. Lwm tus, raws li lawv cov tshuaj muaj pes tsawg leeg, muaj cov organic thiab carboxylic acids. Tsis tas li ntawd, nyob rau hauv lub ntiaj teb niaj hnub no, cov khoom ntxiv los ntawm kev sib xyaw ntawm cov ntsev ntawm cov organic thiab inorganic acids tau tshwm sim. Txhawm rau txiav txim siab qhov sib txawv ntawm lawv tus kheej, lawv tau muab faib ua plaub hom: tsoos, carboxylate, hybrid, lobrid.
Txij li thaum pib ntawm thawj G11 antifreeze los ntawm Volkswagen nyob rau hauv 1984, thev naus laus zis tau nce mus tom ntej, ua tsaug rau qhov no, G12 antifreeze hom tau tshwm sim thiab hauv 2012, ua tsaug rau kev sib ntaus rau ib puag ncig, G13 antifreeze tau tso tawm los ntawm ib puag ncig cov khoom lag luam.
Thawj G11 antifreeze, zoo li Tosol, belongs rau cov tshuaj tiv thaiv kab mob. Lawv siv inorganic compounds raws li additives: silicates, phosphates, borates, nitrites, nitrates, amines, uas tsim ib tug tiv thaiv txheej thiab tiv thaiv corrosion. Cov yeeb yaj kiab tiv thaiv uas nws tsim tau zoo li tawg thaum lub sijhawm, tig mus rau hauv ib qho nyuaj abrasive uas txhaws cov kua dej thiab ua rau muaj kev puas tsuaj rau lub tshuab hluav taws xob lossis lub twj tso kua mis. Lub txee lub neej ntawm cov kua dej no tsis ntev, lawv ua haujlwm tsis pub ntau tshaj ob, peb xyoos. Cov txheej txheem tiv thaiv uas lawv tsim ua rau cov cua sov hloov pauv, uas ua rau muaj kev ua txhaum ntawm qhov kub thiab txias, yog li xyoo 1996, G12 hom tau tshwm sim nrog cov khoom ntxiv los ntawm cov organic thiab carboxylic acids.
Lub hauv paus ntsiab lus ntawm kev tiv thaiv corrosion hauv G12 antifreezes yog raws li qhov cuam tshuam ncaj qha rau thaj tsam corrosive. Additives los ntawm cov organic thiab carboxylic acids tsis tsim ib tug tiv thaiv zaj duab xis nyob rau saum npoo ntawm lub system, tab sis ua ncaj qha rau lub tsom xam uas tau tshwm sim, uas txhais tau hais tias lawv tsis tiv thaiv lub system, tab sis tsuas yog pab rau kev kho mob ntawm ib tug twb tsim teeb meem. . Lub neej kev pab cuam ntawm xws li antifreeze yog los ntawm peb mus rau tsib xyoos.
Hauv G12 + antifreeze, cov tuam txhab txiav txim siab tshem tawm qhov tsis muaj kev tiv thaiv lub cav thiab txiav txim siab los ua ke cov khoom ntawm silicate thiab carboxylate technologies, tsim kom muaj kev sib xyaw ua ke uas, ntxiv rau carboxylic acids, txog 5% ntawm inorganic additives. Ntau lub teb chaws siv cov khoom xyaw sib txawv: nitrites, phosphates lossis silicates.
Nyob rau hauv 2008, ib chav kawm ntawm antifreezes G12 ++ tshwm sim, ua tsaug rau ib qho kev txhim kho mis, nws combines tag nrho cov zoo ntawm cov organic thiab inorganic acids. Kev tiv thaiv corrosion ntawm lub tshuab cua txias, cav phab ntsa, yog ntau dua nrog nws.
Technology tau txav mus rau pem hauv ntej thiab ethylene glycol coolants tau hloov los ntawm propylene glycol coolants, nyob rau hauv ib puag ncig tus phooj ywg. Antifreeze G13, zoo li G12 ++, belongs rau hom lobrid, nws muaj propylene glycol cawv thiab ntxhia additives, vim hais tias lawv ua ib tug lubricating thiab tiv thaiv corrosion, tsis crystallize nyob rau hauv lub qis kub thiab muaj ib tug haum siab. boiling point, tsis txhob cuam tshuam qhov chaw ua los ntawm roj hmab thiab polymers.
Txhua hom tshuaj tiv thaiv kab mob yog pleev xim rau hauv cov xim sib txawv, tab sis txawm tias muaj xim tib yam, los ntawm cov tuam txhab sib txawv, qhov sib txawv tuaj yeem sib txawv. Qhov feem ntau staining ntawm tsoos antifreezes yog xiav los yog ntsuab. Carboxylate muaj xim liab, txiv kab ntxwv lossis liab dawb. Cov tiam tshiab antifreezes, propylene glycol, yog pleev xim rau xim liab los yog daj.
Mixing antifreezes, ntau hom
Txhawm rau xaiv cov tshuaj tiv thaiv kab mob uas zoo tshaj plaws hauv kev sib xyaw, koj yuav tsum xav txog cov khoom siv lub cav thiab lub tshuab hluav taws xob ntawm koj lub tsheb yog dab tsi, vim tias cov additives uas muaj nyob rau hauv cov khoom muaj kev cuam tshuam sib txawv nrog txhuas, tooj dag lossis tooj liab qhov chaw, koj yuav tsum tau hloov cov khoom siv. kua dej sai li sai tau, tsis hais lub sij hawm twg nws haum. Ua tib zoo nyeem cov lus qhia tshwj xeeb rau koj lub tsheb thiab xaiv cov tshuaj tiv thaiv kab mob raws li cov chav kawm kam rau ua tau teev nyob rau ntawm daim ntawv lo.
Thaum ntxiv cov tshuaj tua kab mob, koj yuav tsum tsis txhob cia siab rau cov xim ntawm cov kua, tab sis ntawm nws cov cim, thiaj li tsis txhob sib tov cov tshuaj sib txawv uas muaj nyob rau hauv cov additives.
Nco ntsoov tias yog tias koj sib tov cov kua dej sib txawv, tsis muaj dab tsi phem yuav tshwm sim, tab sis nag lossis daus yog ua tau, thiab cov tshuaj tiv thaiv kab mob yuav tsis tiv nrog nws lub luag haujlwm tseem ceeb, sai li sai tau qhov kev hloov ua tiav yuav tsum tau ua, thiab tej zaum tsis yog tsuas yog cov tshuaj tiv thaiv kab mob. nws tus kheej.
