Qhov tseeb daim ntawv thov ntawmsib tsookua yog ib qho tseem ceeb heev rau kev sib tsoo zoo.Lub luag haujlwm ntawm kev sib tsoo kua yog kom txias thiab lubricate qhov chaw txiav arc.Kev ua haujlwm ntawm dej-raws li kev sib tsoo kua yog tsuas yog kom txias thiab ntxiv rau lubricate.Cov roj txias yog tsuas yog siv rau lubrication thiab muaj qhov txias me ntsis.Cov dej sib tsoo cov kua dej nrog cov khoom siv hluavtaws tag nrho yog qhov tsim nyog tshaj plaws rau cov ntse thiab muaj zog sib tsoo lub log.Hom kev sib tsoo no feem ntau muaj qhov ntev txiav arc thaum ua haujlwm, thiab xav tau cov txiaj ntsig zoo dua.
Semi hluavtaws additive sib tsoo kua yog tsim nyog rau kev sib tsoo complex duab thiab xav tau zoolubricationkev ua tau zoo los tiv thaiv kev kub nyhiab.Cov roj ntshiab yog tsim rau kev sib tsoo cov duab, luv luvtxiavarc thiab siab xav tau rau kev sib tsoo tiav.ethylene glycol raws li kev sib tsoo kua yog tsim rau lub sijhawm uas cubic boron nitride sib tsoo log siv thiab cov roj ntshiab yuav tsum zam.
Kev xaiv cov kua dej sib tsoo yog ib txoj haujlwm nyuaj: ob qho tib si thawj tus nqi ntawm cov dej sib tsoo thiab cov nqi ntawm nws cov kev tswj thiab kev kho mob yuav tsum tau txiav txim siab.Qhov hu ua ib puag ncig-phooj ywg "ntsuab" coolant tsuas yog kev dag ntxias.Qee cov dej txias txias tuaj yeem haus cawv, tab sis ib zaug cov khib nyiab sib tsoo ua rau cov kua paug, nws yuav dhau los ua cov khoom pov tseg rau ib puag ncig.Thaum xaiv cov dej sib tsoo, nws yuav tsum tau lim thiab khaws cia.Nws tsis yog tsuas yog tsim nyog los xav txog nws qhov kev huv, tab sis kuj tswj nws cov concentration, conductivity thiab PH nqi.
Qhov kev sim tshiab tshaj plaws ntawm kev sib tsoo cov kua dej qhia tau hais tias kev cuam tshuam ntawm kev sib tsoo kua concentration ntawm cov txheej txheem sib tsoo tsis yog linear.Rau lub sijhawm ntev, nws tau ntseeg tias cov txheej txheem sib tsoo yuav raug kho kom zoo dua qub nrog rau kev sib tsoo cov kua dej ntau ntxiv, uas tsis yog qhov tseeb.Piv txwv li, thaum lub concentration ntawm cov dej sib tsoo yog 7.5% ~ 8%, nws cov kev ua tau zoo tsis zoo li ntawm 5%, tab sis thaum lub concentration nce mus rau 10% ~ 12%, nws cov kev ua tau zoo tuaj.
Cov txiaj ntsig ntawm 50 hom dej sib tsoo cov kua dej zoo sib xws nrog qhov sib txawv me ntsis.Txawm li cas los xij, qee zaum, qhov sib txawv tsis pom tseeb;Hauv lwm qhov xwm txheej, qhov sib xyaw ntawm 7.5% cov kua dej sib tsoo yuav luag txaus ua rau lub tshuab cuab yeej nres;Cov dej sib tsoo nrog cov concentration ntawm 5% thiab 10% ua haujlwm zoo.
