Feem ntau cov kev ua yuam kev nrog tshuaj tua kab mob
Txheem
Raws li peb ntxub kev lees paub nws, lub caij ntuj sov yuav los txog qhov kawg thiab nws yog lub sijhawm los npaj peb lub tsheb kom npaj tau rau lub hlis txias. Qhov uas yuav tsum tau kuaj cov qib txias. Tab sis nyob rau hauv no zoo li yooj yim ua hauj lwm, hmoov tsis, feem ntau heev yuam kev tau ua.
Kuv tuaj yeem ntxiv tshuaj tua kabmob?
Yav dhau los, refilling antifreeze yog ib txoj haujlwm yooj yim heev, vim tias tsis muaj kev xaiv hauv khw Bulgarian, thiab txawm tias thaum muaj, txhua tus muaj tib lub mis. Txawm li cas los xij, tam sim no qhov no tsis yog qhov tseeb. Yam tsawg kawg yog peb cov tshuaj tiv thaiv kab mob rau kev muag khoom uas yog qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, tsis sib haum nrog ib leeg - Yog tias koj xav tau ntxiv, koj yuav tsum ceev faj heev kom nkag mus rau hauv qhov muaj pes tsawg leeg. Kev sib xyaw ob hom sib txawv tuaj yeem tshem tawm lub tshuab hluav taws xob thiab lub tshuab cua txias.
Muaj ib qho ntxiv: lub sijhawm dhau mus, cov tshuaj kuab tshuaj ua rau cov tshuaj tiv thaiv kev puas tsuaj ploj rau lawv lub zog. Yog li ntawd, nyob ntawm hom, nws yuav tsum tau hloov kiag li txhua ob rau tsib xyoos. Lub caij nyoog ntev tiv thaiv mus rau ib lub sijhawm ntev dua tuaj yeem ua rau cov kev tso nyiaj tsis haum ntawm cov kav dej thiab tshuab xa hluav taws xob.
Lub ntsiab ntawm cov tshuaj tua hluav taws
Yuav luag txhua hom kua rau lub tshuab ua kom txias yog ib qho kev daws ntawm ethylene glycol (los yog, raws li niaj hnub tshaj plaws, propylene glycol) thiab dej. Qhov sib txawv loj yog qhov sib ntxiv ntawm "corrosion inhibitors", piv txwv li cov khoom uas tiv thaiv lub tshuab hluav taws xob thiab cov kab ke los ntawm xeb.
Nyob rau lub sijhawm ntawd, cov kua ntawm IAT hom predominate, nrog inorganic acids raws li corrosion inhibitors - thawj phosphates, thiab ces, rau ib puag ncig yog vim li cas, silicates. Rau cov no, cov tsheb laus dua 10-15 xyoo feem ntau hloov kho. Txawm li cas los xij, IAT antifreeze tsuas kav ntev li ob xyoos thiab tom qab ntawd yuav tsum tau hloov.
Ntau lub tsheb niaj hnub no tau yoog rau cov tshuaj tiv thaiv kab mob OAT, uas cov silicates tau hloov los ntawm azoles (cov molecules nyuaj uas muaj nitrogen atoms) thiab cov organic acids ua corrosion inhibitors. Lawv muaj zog dua - feem ntau mus txog tsib xyoos.
Kuj tseem muaj lub npe ntawd. HOAT lossis kua dej sib txuas, uas yog qhov tseem ceeb ua ke ntawm thawj ob hom nrog silicates thiab nitrites tib lub sijhawm. Carboxylates kuj tseem muaj nyob hauv EU cov qauv uas tau pom zoo. Lawv tsim nyog rau cov neeg mob hnyav dua, tab sis muaj lub sijhawm luv dua thiab xav tau hloov ntau dua.
Txhua ntawm peb hom muaj sib txuam nrog lwm tus.
Peb puas tuaj yeem qhia lawv sib nrug los ntawm lawv cov xim?
Tsis muaj. Cov xim ntawm antifreeze nyob ntawm qhov ntxiv dye, thiab tsis nyob ntawm nws cov tshuaj formula. Qee cov tuam txhab siv xim los qhia hom - xws li ntsuab rau IAT, liab rau OAT, txiv kab ntxwv rau HOAT. Hauv Japanese antifreeze, xim qhia tias qhov kub thiab txias nws yog npaj rau. Lwm tus siv cov xim indiscriminately, yog li nco ntsoov nyeem daim ntawv lo.
Qee cov tuam txhab siv cov ntsiab lus "coolant" thiab "antifreeze" interchangeably. Rau lwm tus, coolant twb diluted kua, npaj siv, thiab antifreeze tsuas yog hu ua undiluted concentrate.
Ntau npaum li cas thiab cov dej zoo li cas ntxiv?
Cov kws tshaj lij pom zoo kom ntxiv cov dej distilled, vim tias muaj ntau cov impurities hauv cov dej zoo tib yam uas tso rau ntawm phab ntsa ntawm cov kav dej thiab lub tshuab hluav taws xob. Tus nqi ntawm dilution nyob ntawm seb hom tshuaj tiv thaiv kab mob thiab cov xwm txheej uas koj yuav siv nws - qhov kub thiab txias yuav tsum tau diluted coolant tsawg dua.
Puas yog nws yuam ua raws li cov khw tsim?
Yuav luag txhua lub tuam txhab tsim tsheb pom zoo kom muab qee hom, lossis txawm tias muaj ntau hom tshuaj tua tsiaj. Ntau tus neeg xav tias qhov no tsuas yog ib txoj hauv kev rau cov tuam txhab kom tuav koj lub hnab nyiaj, thiab peb tsis liam lawv. Tab sis muaj feem ntau muaj laj thawj txaus hauv cov lus pom zoo. Cov tshuab cua txias niaj hnub no nyuaj heev thiab feem ntau yog tsim rau cov haujlwm tsim tshwj xeeb tsis haum. Thiab kuaj kom haum rau lwm hom kua hauv lub cev yog qhov nyuaj, siv sijhawm thiab kim, yog li cov tuam ntxhab feem ntau zam nws. Lawv xaj cov kua ntawm qhov xav tau zoo los ntawm lawv tus kws tsim haujlwm ua ke thiab tom qab ntawd hais kom cov neeg siv khoom siv nws.
