Thaum refueling lub tsheb lub txias system, koj yuav tsum nyeem cov lus qhia uas muaj cov ntaub ntawv nyob rau hauv yuav ua li cas dilute lub antifreeze concentrate. Nws txawv ntawm qhov ua tiav antifreeze, uas tsis tas yuav tsum tau ntxiv dej. Cov muaj pes tsawg leeg ntawm cov khoom yog xws li cov khoom siv lead ua tsis tsim nyob rau hauv nws ntawm qhov kub thiab txias. Txawm li cas los xij, ua ntej nchuav, nws raug nquahu kom coj mus rau hauv tus account qhov pib khov ntawm cov concentrate.

Ntau yam ntawm cov coolant

Cov lus qhia rau cov khoom qhia qhia yuav ua li cas kom dilute cov tshuaj tiv thaiv kab mob. Cov ntaub ntawv raug muab tso rau ntawm lub ntim ntim lossis ncaj qha rau ntawm lub thawv kua nws tus kheej. Cov txheej txheem ntawm kev npaj ntawm lub coolant nyob ntawm seb muaj pes tsawg leeg.

Cov hom tshuaj tiv thaiv hauv qab no yog qhov txawv:

• Ib txwm - cov no tau siv los ntawm cov tswv ntawm kev lag luam tsheb hauv tsev. Antifreeze thiab nws cov analogues raug cais raws li cov khoom siv tsis siv neeg, tab sis qee tus neeg tsav tsheb tseem siv cov cuab yeej pheej yig. Nws tsis yog diluted, tab sis nyob rau hauv qhov chaw sov, cov neeg tsav tsheb tuaj yeem ntxiv dej kom txuag tau nyiaj.
• Hybrid - hybrid coolants. Cov muaj pes tsawg leeg suav nrog ntau hom tshuaj ntxiv uas muaj txiaj ntsig zoo rau cov kab noj hniav sab hauv ntawm lub cev muaj zog thiabcua txias system. Muaj peb hom tshuaj nyob ntawm cov chaw tsim khoom: Japanese thiab Kauslim keeb kwm - phosphates, American - nitrites, European - silicates.
• Lobrid - suav nrog ob hom inhibitors: ntxhia thiab organic.
• Carboxylate - ruaj khov. Lub neej ua haujlwm ntev yog vim txoj kev ua haujlwm siab: cov tshuaj nquag ua haujlwm tsuas yog thaum corrosion tau tsim. Tom qab ntawd, ib zaj duab xis tiv thaiv tshwm rau ntawm qhov chaw uas xeb tshwm.

Txoj cai dav dav

Ua ntej koj dilute cov tshuaj tiv thaiv kom tsis muaj zog, koj yuav tsum paub koj tus kheej nrog cov kev xaiv tsis raug rau cov txheej txheem. Kev ua txhaum ntawm thev naus laus zis ua rau kev kho tsheb kim. Ib qho ntawm cov ntsiab lus tseem ceeb hauv kev npaj cov coolants yog txwv tsis pub sib xyaw ntau hom inhibitors. Rau qhov no, kev sib xyaw ntawm lawv cov xim feem ntau tau npaj.

Tab sis tsis yog tib qho ntxoov ntxoo qhia ib yam zoo sib xws. Yog tias tsis muaj qhov tseeb txog lub hauv paus chiv keeb ntawm cov kua uas tau nchuav rau hauv lub tank, nws yog qhov zoo dua rau ncuav tawm cov tshuaj tiv thaiv. Yuav ua li cas yug cov sib tov tshiab, koj tuaj yeem paub thaum yuav ntawm lub tsheb muag.

Nws feem ntau yog 50/50 piv thaum topping antifreeze. Seb yuav ncuav undiluted concentrate yog nyob ntawm tus tswv lub tsheb txiav txim. Muaj ntau qhov tsis zoo thaum siv cov tshuaj tsis ntxiv dej:

• Hloov lub coolant yuav dhau los ua tus txheej txheem kim.
• Cov khoom ntxiv uas tiv thaiv cov hlau los ntawm overheating thiab corrosion xav tau cov dej molecules kom ua haujlwm zoo.
• Ib qho sib tov tuab yuav kub sai sai thiab ncav cuag qhov kub sai dua.
• Lub neej kev pab cuam ntawm cov khoom raug txo vim yog qhov sib txawv ntawm qhov sib tov qis. Lub twj tso kua mis - lub twj tso kua mis - yog tsim los rau qee yam viscosity. Vim lub xeev undiluted, cov node yuav poob sai.

Qhov tseem ceeb ntawm cov dej txias tsis muaj

Raws li txoj cai, lawv raug coj los ntawm cov qauv hauv qab no thaum xaiv lub tshuab ua kom txias: qhov kub ntawm cov tshuaj tiv thaiv kab mob thiab qhov chaw khov. Cov tshuab niaj hnub ua haujlwm ntawm qhov kub siab tshaj 100 degrees. Yog li ntawd, cov khoom qub qub tsis tuaj yeem siv tau lawm.

Los ntawm txoj kev, koj yuav tsum paub tsis yog yuav ua li cas kom dilute lub concentrate. Antifreeze qee zaum hloov xim dhau ntawm nws lub neej kev pabcuam. Nws yog nyob rau ntawm qhov ntxoov ntxoo ntawm qhov sib tov uas ntau tus neeg tsav tsheb tau coj thaum lawv yuav hloov lub coolant.

Lub Neej Ntawm Khoom:

• carboxylate khaws cov khoom rau ntau tshaj 5 xyoos;
• hybrid tiv thaiv los ntawm 3 mus rau 4 xyoos;
• ib txwm ua haujlwm tsis pub dhau 2 xyoos.

Raws li kev pabcuam lub neej, nws raug nquahu kom paub yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws raug nquahu kom siv cov tshuaj tua kab mob. Tom qab tag nrho, yog tias koj ntxiv cov carboxylate sib tov rau cov khoom qub, koj yuav tsum tau hloov cov kua ua ntej tshaj hnub kawg. Tab sis qhov xwm txheej yuav tshwm sim thaum cov tshuaj thickens vim muaj tshuaj tiv thaiv. Ces txoj kev thauj mus los yuav ua tsis tau kiag li.

Coolant npaj sequence

Cia peb xav txog yuav ua li cas yugantifreeze. Cov concentrate yog stirred nkaus xwb nrog distilled dej nyob rau hauv ib tug npaum li cas sib npaug zos rau lub ntim ntawm thawj cov khoom. Tag nrho cov kev tswj hwm tau ua tiav ua ntej nchuav rau hauv lub tank nthuav dav, siv lub thawv huv.

Yuav ua li cas dilute antifreeze (ntse) paub nyob rau hauv ib lub khw kho tsheb. Txhawm rau kom tsis txhob ua yuam kev nrog kev xaiv cov tshuaj uas tsim nyog, nws raug nquahu kom sab laj nrog tus kws kho mob tshwj xeeb. Feem ntau cov tuam txhab tsheb hloov cov kua dej ntawm lawv qhov kev txiav txim siab. Qhov no tej zaum yuav yog vim muaj kev sib tsoo me me thaum lub sij hawm thauj mus los, thaum cov kav dej tawg los yog cov clamps kaw tsis zoo.

Txoj cai npaj kev sib tov

Tsuas yog cov dej distilled ntxiv rau cov concentrate. Feem ntau, cov neeg tsav tsheb ntxiv cov kais dej. Qhov no yuav rhuav tshem lub kaw lus ua ntej ntau, txawm tias muaj cov tshuaj ntxiv.

kais dej muaj ntsev, minerals, xeb, thiab lwm yam deposits. Lawv yuav sai sai nyob rau hauv lub puab phab ntsa ntawm lub cav grooves nyob rau hauv tus ntawm cov kub kub. Cov kws tshaj lij craftsmen pom zoo kom me ntsis overestimating tus nqi ntawm antifreeze - txoj kev no cov kev daws yuav ua hauj lwm zoo dua.

Rau kev sib xyaw kom raug, tag nrho cov tshuaj ntxiv rau hauv lub thawv cais, tom qab ntawd nchuav los ntawm caj dab mus rau hauv lub tsheb. Nws yog ib qho tseem ceeb los tiv thaiv kev tsim ntawm lub hnab ntim cua. Yog tias huab cua ntau dhau tsis tso tawm, ib qho chaw txias yuav kub sai sai thiab qee cov khoom ntxiv yuav siv tsis tau.

Vim li cas cov chaw tsim khoom tsis npaj tam sim ntawd?

Cov concentrate muaj cov tshuaj nquag ethylene glycol - qhov no yog 93% ntawm tag nrho cov ntim. Xws li qhov sib tov khov ntawm -13 degrees, uas tsis tso cai rau lub tsheb ua haujlwm nyob rau sab qaum teb. Thaum sib xyaw nrog cov dej distilled muag hauv cov chaw muag tsheb, pom muaj tshuaj lom neeg cov tshuaj tiv thaiv. Cov kev daws teeb meem tau npaj txhij los tiv thaiv -38 degrees.

Qhov thib ob yog vim li cas muab cov concentrate yog kom txuag tau qhov chaw thaum xa cov tshuaj tiv thaiv rau cov khw muag khoom. Thaum muag cov khoom sib xyaw ua kom txias, nws yuav tsum tau nrhiav lwm ib nrab ntawm cov ntim ntim hauv warehouses, uas yuav ua rau kom nce nqi ntawm cov khoom.
