Tus tsim ntawm txhua lub tsheb muab qhov cua txias. Nws ua haujlwm kom tshem tawm cov cua sov uas tshwm sim thaum lub tshuab ua haujlwm rau sab nraud. Nyob rau lub caij ntuj no, kev ua haujlwm ntawm cov cua txias ua rau cov cua sov ntawm cov neeg caij tsheb. Niaj hnub no peb yuav txiav txim siab seb nws puas tuaj yeem sib tov tshuaj tiv thaiv kab mob sib txawv ntawm cov xim sib txawv, thiab tseem pom qhov sib txawv ntawm cov kua los ntawm qhov ntxoov ntxoo.

yam ntxwv

Ua ntej tshaj plaws, peb nco ntsoov tias txhua yam coolant, xws li txawv teb chaws lossis Lavxias teb sab ntau lawm, tsis muaj xim. Qhov xwm txheej no tsis cuam tshuam qhov zoo ntawm txhua txoj kev. "Tab sis vim li cas lawv thiaj muaj ntau xim?" - koj nug. Yam tshuaj tiv thaiv twg xaiv - liab, ntsuab, xiav? Qhov txawv yog dab tsi? Cov neeg tsim khoom faib lawv cov khoom raws li qhov no. Txhua yam kua yog qhov txawv los ntawm qhov muaj cov khoom tiv thaiv uas tiv thaiv kom tsis txhob khov ntawm qhov kub thiab txias. Daim duab no tuaj yeem nyob ntawm qhov kub ntawm 15 mus rau 40 degrees Celsius. Peb mam li saib qhov sib txawv hauv qab no.

Qhov txawv yog dab tsi

Chaw tsim khoom hauv cov xim sib txawvkos antifreeze - liab, ntsuab, xiav. Qhov txawv yog dab tsi?

Red muaj qhov ua kom muaj crystallization siab. Nws tsis khov ntawm qhov kub txog li 40 degrees. Nyob rau tib lub sijhawm, nws muaj lub neej ua haujlwm siab - txog li tsib xyoos. Tom ntej no yog ntsuab. Cov tshuaj tiv thaiv no khov ntawm qhov kub ntawm 25 degrees Celsius. Lawv lub neej ua haujlwm yog peb xyoos. Thiab qeb kawg yog xiav (aka "antifreeze"). Ua haujlwm tsawg kawg - 1-2 xyoos. Tab sis qhov ntsuas kub ntawm qhov khov yog qhov siab tshaj plaws thiab yog rho tawm 30 degrees Celsius.

pab pawg

Yog li, cov tuam txhab xa tawm txhua xim rau ib chav kawm. Muaj ob peb ntawm lawv:

• G11.
• G12.
• G13.

Txhua pab pawg muaj nws tus kheej ntxoov ntxoo. Hauv qab no peb yuav saib cov tshuaj tiv thaiv kab mob los ntawm cov xim thiab pom cov yam ntxwv ntawm txhua pawg.

Green

Cov tshuaj tiv thaiv kab mob no yog rau thawj pab pawg. Nyob rau hauv nws muaj pes tsawg leeg, nws muaj tshuaj thiab organic additives. Lub hauv paus, zoo li txhua tus neeg, yog ethylene glycol. Tsis tas li ntawd, ntsuab antifreeze muaj silicates thiab ib feem me me ntawm carboxylic acid. Qhov sib tov no, raws li nws tau, "pob ntawv" tag nrho cov sab hauv ntawm lub tshuab cua txias nrog ib zaj duab xis thiab nquag tawm tsam cov hnab ris corrosion.

Ntawm qhov zoo ntawm kev siv cov tshuaj tiv thaiv zoo li no, nws yog ib qho tsim nyog yuav tsum nco ntsoov cov khoom tiv thaiv corrosion siab. Ua tsaug rau cov yeeb yaj kiab, lub kaw lus ua haujlwm rau lub sijhawm ntev thiab tsis xeb hauv kev ua haujlwm sib txawv. Ntawm qhov tsis txaus yog lub neej ua haujlwm qis, uas yog peb xyoos. Nws tseem yog ib qho tsim nyog yuav tsum nco ntsoov qhov tsis tshua muaj cua sov dissipation, uas yog tiv thaiv los ntawm tib zaj duab xis. Thaum kawg ntawm nws lub neej, antifreeze pib tsim deposits nyob rau hauv lub txias system. Yog tias nws tsis hloov raws sijhawm, nws tuaj yeem txhaws cov kab me me hauv lub cav.

Red

Qhov kev hloov kho no (G12) yog qib siab dua.

Ntawm no nyob rau hauv muaj pes tsawg leeg - organic additives thiab carboxylic acid. Qhov sib tov no tsis tsim cov yeeb yaj kiab hauv cov channel, uas txhim kho cov cua sov. Nws kuj localizes xeb vim qhov kev txiav txim ntawm carboxylic acid. Thaum lub sij hawm, liab antifreeze tsis precipitate. Ntawm kev muag khoom muaj ntau dua li ntsuab. Ntawm qhov tsis txaus, nws yuav tsum raug sau tseg tias lawv tsis tiv thaiv aluminium radiators los ntawm oxidation. Tab sis yog tias koj muaj tooj liab lossis tooj dag, liab antifreeze yog qhov kev xaiv zoo tshaj plaws.

Purple

Peb ob peb tug tau pom lawv nyob, tab sis cov cuab yeej no kuj muaj. Lawv tau tshwm sim tsis ntev los no - hauv 2012. Lawv zwm rau pawg 13th. Ntshav yog ib qho lobrid antifreeze uas tsis muaj ethylene glycol. Nws ntseeg tau tias muaj tshuaj lom heev. Tab sis yuav ua li cas muab cov cua kub dissipation yog tias cov ntsiab lus tseem ceeb tsis muaj ethylene glycol? Xwb, manufacturers siv ntau tus phooj ywg ib puag ncig, propylene glycol. Nws tsis muaj tshuaj lom thiab ib puag ncig zoo. Raws li rau lwm yam khoom, violet antifreeze muaj silicates thiab carboxylic acid, twb paub rau peb raws li ib tug anti-corrosion neeg sawv cev nyob rau hauv yav dhau los pawg.

Blue

Ntawm no yog txhua tus paubpeb antifreeze, uas tshwm sim nyob rau hauv 70s nyob deb ntawm lub xyoo pua xeem. Nws muaj 20 feem pua ntawm cov dej distilled. Txhua yam yog ethylene glycol. Raws li qhov kev faib ua feem no, tshuaj tiv thaiv kab mob muaj qhov kub thiab txias txog li 30 degrees Celsius. Los ntawm txoj kev, tag nrho lwm cov "xim" analogues suav nrog tsuas yog 5 feem pua ntawm cov dej distilled.

Yog li ntawd, tshuaj tiv thaiv kab mob feem ntau boils. Twb tau ntawm 110 degrees nws ua tsis tau zoo. Thiab muab hais tias qee lub cav ntawm cov tsheb txawv teb chaws muaj qhov kub thiab txias ntawm "ntau pua", ces siv cov cuab yeej no hauv lawv tsuas yog txaus ntshai. Qhov no yuav twv yuav raug hu overheat lub cav. Yog li ntawd, antifreeze tsuas yog tsim rau cov tsheb hauv tsev, tsis muaj ntxiv lawm. Thiab nws muaj lub neej ntev txog li ob xyoos. Nyob rau hauv xyoo tsis ntev los, nws cov thermal dissipation zog txo. Tib cov tshuaj tiv thaiv liab liab "nourishes" tsib xyoos yam tsis muaj teeb meem. Tab sis hais txog tus nqi, nws yog 50-80 feem pua ntau dua.

Kuv puas tuaj yeem muab cov xim sib txawv ntawm cov tshuaj tiv thaiv kab mob?

Yog li, xav txog qhov xwm txheej: thaum koj sawv, koj mus rau hauv chav nres tsheb thiab xyuas cov dej txias. Koj qhib lub hau, thiab nws yog qhov tsawg kawg nkaus. Yuav ua li cas? Puas muaj peev xwm sib tov antifreeze ntawm cov xim sib txawv? Nws yog qhov ua tsis tau kiag li.

Thiab txawm tias cov xim ntawm cov tshuaj tiv thaiv kab mob yog tib yam. Cov khoom ntawm txhua tus neeg tsim khoom yuav txawv heev. Vim li cas koj tsis tuaj yeem sib tov tshuaj tiv thaiv ntawm cov xim sib txawv? Xws li ib qho kev txiav txim tuaj yeem cuam tshuam qhov muaj pes tsawg leeg thiab hloov qhov feem ntawm cov additives. Vim li no, ntawm qhov kub thiab txias ntawm lub cav, cov kua yuav ua npuas. Hauv qhov no, lub dab dej kub yuav tsawg, thiab yog tias koj tsis pom qhov teeb meem hauv lub sijhawm (uas tshwm sim hauv 90 feem pua), koj tuaj yeem yooj yim overheat lub cav. Tsis tas yuav sim thiab xav tias "Yuav ua li cas cov tshuaj tiv thaiv kab mob tuaj yeem sib xyaw." Cov lus teb yog tib yam - koj ua tsis tau, txawm tias cov xim zoo ib yam.

Zoo kom zoo

Yuav ua li cas yog tias qib hauv lub tank tau poob mus rau qhov tsawg kawg nkaus? Yuav ib lub kaus poom ntawm cov tshuaj tiv thaiv kab mob tshiab yog kim, noj nws hauv ib lub qe me me "rau topping" yog qhov tuag taus rau lub cav. Tab sis txij li tag nrho cov antifreezes muaj cov dej distilled, peb yuav dilute nws nrog nws. Qhov kev faib ua feem yuav tsum tsis pub tshaj ib nrab. Ntawd yog, 50% ethylene glycol - 50% dej distilled. Qhov no yog qhov zoo tshaj yog tias koj xav tau ntxiv cov kua me me rau hauv lub tank. Raws li txoj cai, nws ploj ntawm nws lub sijhawm. Yuav ua li cas yog tias koj sib tov tshuaj tiv thaiv kab mob nrog dej? Nws lub xub ntiag tsis hloov qhov muaj pes tsawg leeg thiab cov khoom ntawm lub coolant. Qhov sib npaug ntawm cov additives tsis cuam tshuam, qhov ntsuas kub tsis nce. Txawm li cas los xij, yog tias koj sau ntau tshaj li ib liter dej, nyob rau yav tsaus ntuj ntawm lub caij ntuj no, koj yuav tsum tau hloov tag nrho cov coolant. Nyob rau hauv loj proportions, xws li ib tug sib tov freezes sai sai. Qhov no yuav tsum tau coj mus rau hauv tus account. Yog tias koj ntxiv tsis pub ntau tshaj 300 milliliters dej distilled rau lub tank, koj tuaj yeem ua yam tsis tau hloov cov tshuaj tiv thaiv kab mob rau lub caij ntuj no.

Lwm yam phom sij

Tam sim no peb paub cov lus teb rau lo lus nug "nws puas tuaj yeem sib xyaw cov xim sib txawv." Txhawm rau ua qhov no, tsuas yog siv cov dej distilled. Hais txog cov kua "los ntawm kais" yuav tsum tsis txhob tawm ntawm lo lus nug. Nws yuav tsis tsuas yog ua phem rau cov khoom ntawm antifreeze, tab sis kuj yog thawj zaugboiling (uas yuav tshwm sim tom qab 20 feeb ntawm kev ua hauj lwm ntawm xws li ib tug cav) yuav tsim scale.

Nws nyuaj heev kom tshem tawm nws. Cov txheej txheem yog nrog los ntawm kev tso dej tsis tu ncua thiab dismantling ntawm lub radiator. Nyob rau hauv qhov phem tshaj plaws, scale clogs me me channel. Tsis txhob siv dej kais dej. Tsuas yog distilled.

Zoo kawg

Yog li, peb pom tias nws puas tuaj yeem sib tov tshuaj tiv thaiv kab mob sib txawv thiab qhov sib txawv ntawm cov kua dej li cas. Thaum muas lub coolant tshiab, nco ntsoov tias txhua yam xim yog qhov kev xaiv ntawm cov chaw tsim khoom. Qee zaum cov kua dej ntawm tib xim tuaj yeem sib txawv heev. Ua tib zoo saib cov pab pawg uas cov khoom lag luam. Kuj xav txog hom ntawm koj lub tsheb. Yog tias qhov no yog lub tsheb txawv teb chaws, koj yuav tsum tsis txhob nchuav tshuaj tiv thaiv rau nws, txawm tias nws yuav kim npaum li cas. Thiab txhawm rau tswj cov qib coolant, khaws ib lub thoob dej distilled.
