01 Coolant Taw Qhia
Coolant, raws li lub npe qhia, nws yog cov khoom ua kua siv los khaws cia txias, nws yuav tsum muaj peev xwm khaws cia txias.Muaj ib yam khoom nyob rau hauv qhov uas yog ib tug zoo coolant, uas yog dej.Nws yog qhov paub zoo tias dej yuav khov rau lub caij ntuj no thaum qhov kub qis dua 0 ° C.Qhov tseeb, cov txheej txheem khov yog tias cov dej ua kua tau hloov mus rau hauv cov dej khov rau hauv lub zog txias.Thaum lub sijhawm txheej txheem no, qhov kub ntawm cov dej khov-dej sib tov yuav nyob ntawm 0 ° C kom txog thaum cov dej hloov pauv mus rau hauv dej khov, thaum lub sijhawm cov dej txias txias yuav xaus.Thaum qhov kub ntawm sab nraud ntawm cov dej khov tsim siab tshaj 0 ° C, cov dej khov yuav nqus cov cua sov ntawm ib puag ncig thiab maj mam yaj mus rau hauv dej.Thaum lub sij hawm dissolving, qhov kub ntawm cov dej khov-dej sib tov yog ib txwm 0 ° C kom txog thaum cov dej khov yog yaj tag rau hauv dej.Lub sijhawm no, lub zog txias uas khaws cia hauv dej tau raug tso tawm.
Nyob rau hauv cov txheej txheem saum toj no ntawm kev sib hloov pauv ntawm cov dej khov thiab dej, qhov kub ntawm cov dej khov dej sib tov yog ib txwm nyob ntawm 0 ℃ thiab yuav kav rau ib lub sijhawm.Qhov no yog vim dej yog ib theem hloov cov khoom ntawm 0 ℃, uas yog characterized los ntawm theem hloov.Cov kua ua kua (exothermic), cov khoom ua kua (endothermic), thiab qhov kub thiab txias yuav tsis hloov rau qee lub sijhawm ntawm lub sijhawm hloov pauv thaum lub sijhawm hloov pauv (uas yog, nws yuav tsis tu ncua nqus lossis tso tawm ntau heev. ntawm tshav kub nyob rau hauv ib lub sij hawm ntawm lub sij hawm).
Feem ntau daim ntawv thov ntawm theem hloov coolant nyob rau hauv peb lub neej txhua hnub yog "preservation" ntawm txiv hmab txiv ntoo, zaub thiab zaub mov tshiab.Cov zaub mov no yooj yim rau deteriorate nyob rau hauv siab ambient kub.Yuav kom ncua lub freshness, peb tuaj yeem siv theem hloov coolant los kho qhov kub thiab txias kom ua tiav cov txiaj ntsig ntawm kev tswj kub thiab kev txuag:
02 Adaim ntawv thov ntawmTxias Cua oolant
Rau cov txiv hmab txiv ntoo, zaub thiab zaub mov tshiab uas xav tau 0 ~ 8 ℃ txias cia, cov khoom ntim cov dej khov txias yuav tsum tau khov ntawm -7 ℃ rau tsawg kawg 12 teev (kom paub meej tias cov ntim dej txias txias tau khov tag) ua ntej xa khoom.Thaum lub sij hawm xa khoom, cov khoom ntim cov dej khov thiab cov khoom noj yuav tsum tau muab tso rau hauv lub thawv txias ua ke.Kev siv cov pob khov nab kuab nyob ntawm qhov loj ntawm lub thawv txias thiab lub sijhawm rwb thaiv tsev.Lub thawv loj dua thiab lub sijhawm rwb thaiv tsev ntev dua, cov pob khov nab kuab yuav siv ntau dua.Cov txheej txheem kev ua haujlwm dav dav yog raws li hauv qab no:
03 Adaim ntawv thov ntawmFrozen Coolant
Rau cov khoom noj khov tshiab uas xav tau 0 ℃ txias cia, cov thawv ntim cov tub yees yuav tsum tau khov ntawm -18 ℃ rau tsawg kawg 12 teev (kom paub meej tias cov thawv ntim cov tub yees txias tau khov tag) ua ntej xa khoom.Thaum lub sij hawm muab faib, cov thawv ntim cov tub yees thiab cov khoom noj yuav tsum tau muab tso rau hauv qhov cub ua ke.Kev siv cov pob khov nab kuab nyob ntawm qhov loj ntawm lub thawv txias thiab lub sijhawm rwb thaiv tsev.Qhov loj dua lub thawv txias thiab qhov ntev ntawm lub rwb thaiv tsev yog, lub ntim dej khov ntau dua yuav raug siv.Cov txheej txheem kev ua haujlwm dav dav yog raws li hauv qab no:
04 Coolant Composition & Cov lus qhia rau kev siv
Nrog rau kev vam meej ntawm tib neeg, tib neeg lub neej zoo tau nce siab dua, thiab qhov zaus ntawm kev yuav khoom hauv online hauv Internet era kuj nce ntxiv.Ntau cov khoom noj tshiab thiab khov yog yooj yim rau deteriorate hauv kev thauj mus los tsis muaj "kub tswj thiab khaws cia".Daim ntawv thov ntawm "theem hloov coolant" tau dhau los ua qhov kev xaiv zoo tshaj plaws.Tom qab cov zaub mov tshiab thiab khov tau zoo tswj tau thiab khaws cia tshiab, tib neeg lub neej zoo tau zoo tuaj.
Nrog rau kev siv ntau zaus ntawm 0 ℃ thiab cov pob khov khov, puas yuav cov dej txias los ntawm kev tawg ntawm cov pob khov nab kuab thaum lub sij hawm thauj mus los ua rau muaj kev hem thawj rau kev nyab xeeb khoom noj?Nws puas yuav ua rau tib neeg lub cev puas tsuaj yog tias noj tsis paub?Hauv kev teb rau cov teeb meem no, peb ua cov lus qhia hauv qab no rau cov pob khov nab kuab:
