Dab tsi yog qhov txawv ntawm antifreeze thiab antifreeze? Dab tsi zoo dua? Lawv puas tuaj yeem sib xyaw?

Thaum peb yuav lub tsheb, peb xav kom nws kav ntev li ntev tau. Lub neej kev pab cuam feem ntau yog nyob ntawm kev ua haujlwm thiab kev pabcuam zoo.

Cov kua siv thev naus laus zis cuam tshuam rau kev ua haujlwm zoo ntawm txhua lub cav cav. Tsis yog lub luag haujlwm kawg yog ua los ntawm lub tshuab ua kom txias, ua tsaug rau lub cav tswj qhov ntsuas kub xav tau.

Yog tias ua ntej, thaum kaj ntug ntawm kev lag luam tsheb, tsheb cav tau ua los ntawm cov hlau cam khwb cia thiab tooj dag, ces cov dej distilled zoo tib yam tuaj yeem nchuav rau hauv lub tshuab hluav taws xob. Thiab nyob rau lub caij ntuj no, ethylene glycol lossis cawv tau ntxiv rau cov dej no kom cov dej khov tsis tuaj yeem tsim hauv lub tshuab hluav taws xob. Txawm li cas los xij, rau cov tsheb niaj hnub, xws li kev sib tov yuav zoo li kev tuag, vim tias nws yuav ua rau cov txheej txheem corrosion hauv lub cav. Yog li ntawd, chemists pib tshawb nrhiav cov kua uas yuav tsis ua rau hlau corrosion.

Qhov no yog li cas automotive antifreeze tau tsim. Cov kev tshawb fawb zoo sib xws tau ua nyob rau hauv Soviet Union, qhov twg nyob rau hauv 70s lawv tau tswj kom tau lawv tus kheej antifreeze formula - Tosol.

Los ntawm qhov no peb tuaj yeem kos cov lus xaus hauv qab no:

• antifreeze thiab antifreeze yog cov kua uas tsis khov ntawm qhov kub thiab txias;
• antifreeze - lub npe no yog siv thoob plaws ntiaj teb;
• antifreeze yog cov khoom lag luam Lavxias nkaus xwb npaj rau cov tsheb tsim hauv USSR thiab niaj hnub Russia.

Lub ntsiab sib txawv ntawm cov tshuaj muaj pes tsawg leeg

Qhov sib txawv tseem ceeb tshaj plaws yog cov tshuaj dab tsi uas muaj nyob hauv cov tshuaj tiv thaiv kab mob thiab tshuaj tiv thaiv kab mob.

Antifreeze muaj cov ntsiab lus tseem ceeb - dej thiab tshuaj tiv thaiv kab mob ntxiv ethylene glycol. Dej yog siv los xa cov tshuaj muaj pes tsawg leeg no mus rau tag nrho cov ntsiab lus ntawm lub cav; ethylene glycol tiv thaiv dej los ntawm khov ntawm qhov kub qis. Nws kuj muaj cov ntsev ntawm inorganic acids. - phosphates, nitrates, silicates, uas yog tsim los tiv thaiv cov hlau los ntawm corrosion. Cov chav kawm ntawm cov tshuaj tiv thaiv kab mob yog nyob ntawm seb cov ntsev ntsev twg siv thiab qhov feem pua ​​​​ntawm cov tshuaj tiv thaiv kab mob ntxiv - uas yog, qhov ntsuas kub qis ntawm qhov khov.

Antifreeze kuj yog tsim los ntawm dej thiab ethylene glycol. Glycerin thiab kev haus cawv kuj tseem ntxiv rau nws (uas yog vim li cas koj tsis tuaj yeem haus tshuaj tiv thaiv kab mob). Tab sis qhov sib txawv tseem ceeb tshaj plaws yog tias tsis muaj ntsev ntawm inorganic tshuaj nyob rau hauv antifreeze; organic ntsevuas ho txhim kho nws cov kev ua tau zoo.

Ntsiab cai ntawm kev ua haujlwm

Txij li thaum cov hlau tsis ntshai ntawm kev sib cuag nrog dej, ob qho tib si antifreeze thiab antifreeze tsim ib txheej tiv thaiv nyias ntawm cov hlau ntsiab ntawm lub cav thiab cov cua txias uas tiv thaiv kev sib cuag ntawm dej thiab hlau. Txawm li cas los xij, muaj qee qhov txawv ntawm qhov no.

Antifreeze circulates los ntawm lub system thiab tsim ib tug nyias zaj duab xis ib nrab ib millimeter tuab ntawm tag nrho cov sab hauv hlau. Vim tias cov yeeb yaj kiab no, kev hloov pauv cua sov yog cuam tshuam, feem, lub cav xav tau roj ntau dua. Qhov no yog ib qho ntawm cov laj thawj uas vim li cas roj noj nce ntxiv rau lub caij ntuj no, peb twb tau kov cov ncauj lus no ntawm peb lub vev xaib autoportal Vodi.su.

Lub xub ntiag ntawm silicate thiab nitrite ntsev ua rau lub fact tias lawv precipitate, ib tug zoo gel zoo li slurry yog tsim, uas maj clogs lub radiator hlwb.

Antifreeze yuav tsum tau hloov ntau zaus - txhua txhua 40-50 txhiab kilometers, nws tsis tuaj yeem nyob ntev, vim tias cov yeeb yaj kiab tiv thaiv raug puas tsuaj los ntawm qhov kub thiab txias thiab lub cav raug hem nrog corrosion. Antifreeze pib boil ntawm kub tshaj 105-110 degrees.

Antifreeze ua haujlwm ntawm tib lub hauv paus ntsiab lus, tab sis nrog qhov sib txawv ntawm cov yeeb yaj kiab tiv thaiv tsuas yog tshwm sim ntawm cov ntsiab lus uas muaj kev cuam tshuam rau corrosion, feem, cov roj noj ntawm cov neeg tsav tsheb pouring antifreeze tsis nce ntau. Tsis tas li ntawd, antifreeze tsis muab xws li precipitate, nws tsis tas yuav tsum tau hloov ntau zaus, cov kua tsis poob nws cov khoom nrog ib tug khiav ntawm ntau tshaj 200 txhiab kilometers. Thaum boiling, antifreeze tsis tsim ua npuas ncauj thiab flakes uas txhaws lub radiator. Yog, thiab nws boils ntawm qhov kub ntawm 115 degrees.

Ntawd yog, peb pom tias yog tias koj xaiv ntawm antifreeze thiab antifreeze, ces nyiam yuav tsum tau muab rau tom kawg.

Tab sis xws li ib qho tseem ceeb raws li tus nqi plays tawm tsam nws - 5-liter canister ntawm antifreeze nqi ib lub nyiaj, thaum tseem ceeb npaum li cas yuav tsum tau them rau antifreeze.

Muaj tseeb, muaj ntau yam cuav ntawm lub khw no: yog tias koj pom cov ntawv sau zoo li "Antifreeze-Silicate", lossis "Antifreeze-Tosol", ces nug tus kws pab tswv yim txog qhov txawv ntawm kev ua kom khov thiab ua kom khov - ntsev ntawm cov organic thiab inorganic acids.

Silicates yog ib pawg ntau ntawm cov zaub mov uas tsis tuaj yeem cuam tshuam nrog cov khoom siv organic, uas yog, lawv tab tom sim muag koj cov tshuaj tiv thaiv kab mob hauv qab cov tshuaj tiv thaiv kab mob.

Nco ntsoov tias antifreeze tsis tas yuav tsum tau diluted nrog dej distilled. Nws qhov txias txias yog feem ntau nyob rau hauv cheeb tsam los ntawm rho tawm 15 mus rau rho tawm 24-36 degrees. Antifreeze, ntawm qhov tod tes, tuaj yeem muag ob qho tib si hauv daim ntawv ntawm kev sib xyaw ua ke thiab hauv daim ntawv ntawm kev mloog zoo. Yog hais tias koj yuav concentrated antifreeze, ces nws yuav tsum tau diluted nyob rau hauv ib tug-rau-ib piv, nyob rau hauv cov ntaub ntawv no lub freezing point yuav yog -40 degrees.

Antifreeze tsis pom zoo kom yuav rau lub tsheb txawv teb chaws. Piv txwv li, Toyota ncuav liab antifreeze.

Koj tsuas tuaj yeem sib tov tshuaj tiv thaiv kab mob ntawm cov xim tib yam, tsis muaj teeb meem koj yuav tsum sib tov antifreeze nrog antifreeze. Ua ntej ntxiv antifreeze, tag nrho cov yav tas los residue yuav tsum tau drained.

Yuav kom lub tshuab kav ntev li ntev tau yam tsis muaj kev puas tsuaj, yuav tsuas yog hom tshuaj tiv thaiv kab mob los yog tshuaj tiv thaiv kab mob uas tau pom zoo los ntawm cov chaw tsim khoom.
