Concentrate los yog npaj ua antifreeze. Dab tsi zoo dua?
Txheem
Antifreeze concentrate muaj dab tsi thiab nws txawv li cas ntawm cov khoom tiav?
Qhov kev npaj txhij-rau-siv antifreeze li niaj zaus muaj 4 yam tseem ceeb:
- ethylene glycol;
- distilled dej;
- pob khoom ntxiv;
- xim.
Cov concentrate yog ploj lawm ib yam ntawm cov khoom: distilled dej. Cov khoom seem nyob rau hauv tag nrho muaj pes tsawg leeg yog nyob rau hauv concentrated versions ntawm coolants. Qee zaum cov tuam ntxhab, txhawm rau ua kom yooj yim thiab tiv thaiv cov lus nug tsis tsim nyog, tsuas yog sau "Glycol" lossis "Ethandiol" ntawm lub ntim, uas, qhov tseeb, yog lwm lub npe rau ethylene glycol. Additives thiab dye feem ntau tsis hais.
Txawm li cas los xij, nyob rau hauv feem ntau ntawm cov neeg mob, tag nrho cov additive Cheebtsam thiab dye yog tam sim no nyob rau hauv tag nrho cov formulations uas ua los ntawm tus kheej-saib manufacturers. Thiab thaum dej ntxiv rau hauv qhov kev faib ua feem, cov zis yuav yog cov tshuaj tiv thaiv zoo tib yam. Niaj hnub no nyob rau hauv kev ua lag luam muaj feem ntau concentrates ntawm antifreezes G11 thiab G12 (thiab nws cov derivatives, G12 + thiab G12 ++). G13 antifreeze yog muag npaj ua.
Hauv ntu pheej yig, koj tuaj yeem pom cov ethylene glycol zoo tib yam, tsis muaj cov khoom ntxiv. Nws yuav tsum tau siv nrog ceev faj, vim hais tias cov cawv no nws tus kheej muaj ib tug me ntsis tshuaj aggression. Thiab qhov tsis muaj cov tshuaj tiv thaiv ntxiv yuav tsis tiv thaiv kev tsim ntawm qhov chaw corrosion lossis nres nws qhov kev sib kis. Uas nyob rau hauv lub sij hawm ntev yuav txo tau lub neej ntawm lub radiator thiab kav dej, raws li zoo raws li nce tus nqi ntawm oxides tsim.
Dab tsi yog qhov zoo dua antifreeze lossis antifreeze concentrate?
Saum toj no, peb pom tias nyob rau hauv cov nqe lus ntawm cov tshuaj muaj pes tsawg leeg tom qab kev npaj ntawm cov concentrate, yuav tsis muaj qhov sib txawv nrog cov khoom tiav. Qhov no yog nrog cov xwm txheej uas cov proportions yuav raug soj ntsuam.
Tam sim no xav txog qhov zoo ntawm cov concentrate tshaj cov khoom tiav tiav.
- Qhov muaj peev xwm ntawm kev npaj tshuaj tiv thaiv kab mob nrog rau qhov chaw khov uas yog qhov zoo rau qhov xwm txheej. Standard antifreezes feem ntau yog ntsuas rau -25, -40 lossis -60 ° C. Yog tias koj npaj lub coolant koj tus kheej, ces koj tuaj yeem xaiv qhov concentration xwb rau thaj chaw uas lub tsheb ua haujlwm. Thiab muaj ib qho kev hloov maj mam ntawm no: qhov siab dua qhov kub thiab txias tsis kam ntawm ethylene glycol antifreezes, qhov qis dua qhov ua rau kub. Piv txwv li, yog hais tias antifreeze nrog ib tug pour point ntawm -60 ° C yog poured rau yav qab teb cheeb tsam, ces nws yuav boiled thaum tshav kub nyob rau hauv lub zos mus rau + 120 ° C. Xws li qhov pib rau "kub" motors nrog kev tsav tsheb hnyav tau yooj yim ua tiav. Thiab los ntawm kev ua si nrog qhov kev faib ua feem, koj tuaj yeem xaiv qhov kev pom zoo ntawm ethylene glycol thiab dej. Thiab lub resulting coolant yuav tsis khov nyob rau hauv lub caij ntuj no thiab yuav resistant rau high kub nyob rau hauv lub caij ntuj sov.
- Cov ntaub ntawv tseeb txog qhov kub thiab txias ntawm qhov diluted antifreeze concentrate yuav khov.
- Muaj peev xwm ntxiv cov dej distilled los yog mloog zoo rau lub kaw lus kom hloov qhov dej taw tes.
- Tsis tshua muaj kev yuav khoom cuav. Concentrates feem ntau yog tsim los ntawm cov tuam txhab muaj koob npe. Thiab ib qho kev tsom xam ntawm kev ua lag luam qhia tau hais tias muaj ntau qhov cuav ntawm cov tshuaj tiv thaiv uas npaj txhij.
Ntawm qhov tsis zoo ntawm kev npaj nws tus kheej ntawm cov tshuaj tiv thaiv kab mob los ntawm kev mloog zoo, ib tus tuaj yeem nco ntsoov qhov yuav tsum tau tshawb xyuas cov dej distilled (nws pom zoo kom tsis txhob siv cov kais dej zoo tib yam) thiab lub sijhawm siv los npaj cov khoom tiav.
Raws li cov lus hais saum toj no, nws yog tsis yooj yim sua hais unequivocally uas yog zoo dua, antifreeze los yog nws concentrate. Txhua qhov sib xyaw muaj nws qhov zoo thiab qhov tsis zoo. Thiab thaum xaiv, koj yuav tsum mus los ntawm koj tus kheej nyiam.
