Antifreeze zoo qauv

Ua ntej: Lub luag hauj lwm ntawm kev ntxiv defoaming tus neeg sawv cev rau antifreeze: Raws li lub tsheb cav yuav inevitably vibrate thaum lub sij hawm ua hauj lwm, huab cua yuav nkag mus rau hauv lub antifreeze los tsim tej yam ua npuas ncauj. Qhov no cuam tshuam rau kev hloov ntawm tshav kub. Thaum tus nqi tsim nyog ntawm defoaming tus neeg sawv cev ntxiv rau cov tshuaj tiv thaiv kab mob, nws tuaj yeem ua lub luag haujlwm defoaming thaum lub concentration ntawm defoaming tus neeg sawv cev mus txog ib qho nyiaj. Defoaming agents mas siv alkyl non-ionic surfactants, feem ntau dehydrated glyceryl ether, cawv, silicones, thiab lwm yam.
Thib ob: Lub luag haujlwm ntawm kev ntxiv cov xim tsis muaj tshuaj lom dej-soluble colorants rau antifreeze: Ntxiv cov xim tsis muaj tshuaj lom dej-soluble xim, thiab (ntau) concentration ntawm cov xim yog feem ntau nyob rau hauv ntau ntawm 0.{{6} 1% mus rau 0.05%. Qhov sib txawv ntawm cov dej txias yog saib xyuas seb cov tshuaj tiv thaiv kab mob hauv lub tshuab ua kom txias yog los. Nyob rau tib lub sijhawm, nws muaj kev siv cov tshuaj reagents, uas yooj yim rau kev soj ntsuam pH hloov ntawm cov tshuaj tiv thaiv. Feem ntau, methyl liab, phenol liab, methyl xiav, thiab lwm yam yog siv ntau dua los muab cov tshuaj tiv thaiv kab mob rau qee yam kev qhia. Yog tias cov xim pom tsis sib haum nrog cov xim qhia, nws txhais tau hais tias cov tshuaj tiv thaiv kab mob yog acidic, thiab acidity yuav tsis ua lub luag haujlwm tiv thaiv kab mob thiab tiv thaiv xeb.
Thib peb: Lub luag haujlwm ntawm kev ntxiv cov bactericides thiab mildew inhibitors rau antifreeze: Vim antifreeze yog nquag tsim cov kab mob thaum lub sij hawm cia, thiaj li yuav inhibit qhov kev loj hlob ntawm cov kab mob thiab tiv thaiv lub antifreeze los ntawm pwm thiab deterioration, ib tug me me ntawm cov bactericides thiab mildew inhibitors yuav tsum tau. muab ntxiv los xyuas kom meej tias cov tshuaj tiv thaiv tsis tuaj yeem pwm thaum lub sijhawm khaws cia ntawm 2-3 xyoo. Ntawm lawv, sodium benzoate kuj zoo.
Plaub: Lub luag hauj lwm ntawm kev ntxiv cov tshuaj tiv thaiv corrosion rau antifreeze: Txij li thaum pH tus nqi ntawm antifreeze yuav poob thaum lub sij hawm ua hauj lwm, qhov nruab nrab yuav ua acidic, thiab qhov sib ntxiv ntawm corrosion inhibitors tuaj yeem tswj cov pH tus nqi nyob rau hauv ib qho chaw. Feem ntau siv pH regulators muaj xws li cov organic amines, phosphates thiab phosphates.
Thib tsib: Cov qauv tseem ceeb thiab kev soj ntsuam cov txheej txheem ntawm kev tiv thaiv kab mob: Cov cim tseem ceeb tau teev tseg hauv cov qauv tshuaj tiv thaiv kab mob muaj xws li qhov ntom ntom, solubility, dej twj cavitation corrosion, foaming, (pH nqi) acidity, boiling point, antifreeze (kub point), xim hloov, cia alkalinity, hlau corrosion, thiab lwm yam.
