Cov tshuaj muaj pes tsawg leeg ntawm antifreeze g11, g12, g13
Kev sib xyaw ua ke
Lub hauv paus ntawm coolants (coolant) yog dej distilled tov nrog mono- thiab polyhydric alcohols nyob rau hauv ntau yam proportions. Corrosion inhibitors thiab fluorescent additives (dyes) kuj tau qhia hauv cov concentrates. Ethylene glycol, propylene glycol los yog glycerin (txog 20%) yog siv los ua cawv.
- dej distillate
Purified, softened dej yog siv. Txwv tsis pub, nplai nyob rau hauv daim ntawv ntawm carbonate thiab phosphate deposits yuav tsim nyob rau hauv lub radiator grille thiab cov phab ntsa ntawm cov kav dej.
- Ethanediol
Dihydric saturated cawv, tsis muaj xim thiab tsw. Toxic oily kua nrog qhov chaw khov ntawm -12 ° C. Nws muaj lubricating zog. Txhawm rau kom tau txais cov tshuaj tua kab mob ua kom tiav, kev sib xyaw ntawm 75% ethylene glycol thiab 25% dej yog siv. Cov ntsiab lus ntawm additives yog tsis quav ntsej (tsawg dua 1%).
- Propanediol
Nws kuj yog propylene glycol - qhov ze tshaj homologue ntawm ethanediol nrog peb carbon atoms nyob rau hauv cov saw. Non-toxic kua nrog ib tug me ntsis bittersweet saj. Kev lag luam antifreeze yuav muaj 25%, 50%, lossis 75% propylene glycol. Vim yog tus nqi siab, nws siv tsawg dua li ethanediol.
Hom tshuaj additives
Ethylene glycol antifreeze rau tsheb oxidizes thaum lub sij hawm ua hauj lwm mus sij hawm ntev thiab tsim glycolic, tsawg dua formic acid. Yog li, ib puag ncig acidic tsis zoo rau cov hlau yog tsim. Txhawm rau tshem tawm cov txheej txheem oxidative, cov tshuaj tiv thaiv corrosion yog nkag mus rau hauv lub coolant.
- Inorganic corrosion inhibitors
Los yog "ib txwm" - sib tov raws li silicates, nitrate, nitrite lossis phosphate ntsev. Xws li additives ua raws li ib tug alkaline tsis thiab tsim ib tug inert zaj duab xis ntawm cov hlau nto, uas tiv thaiv cov teebmeem ntawm cawv thiab nws cov khoom oxidation. Antifreezes nrog inorganic inhibitors raug cim nrog lub npe "G11" thiab muaj xim ntsuab lossis xiav. Inorganic inhibitors muaj nyob rau hauv muaj pes tsawg leeg ntawm antifreeze, ib tug domestically tsim coolant. Kev pab lub neej yog txwv rau 2 xyoos.
- Organic Inhibitors
Vim muaj cov peev txheej tsawg ntawm cov tshuaj inorganic inhibitors, ntau tus phooj ywg ib puag ncig thiab tshuaj tiv thaiv cov tshuaj tiv thaiv, carboxylates, tau tsim. Cov ntsev ntawm carboxylic acids tsis tiv thaiv tag nrho cov chaw ua haujlwm, tab sis tsuas yog qhov chaw ntawm corrosion, npog thaj tsam nrog ib daim duab nyias. Tsim los ua "G12". Kev pab lub neej - txog li 5 xyoos. Lawv muaj xim liab lossis liab dawb.
- sib xyaw
Qee zaum, "organics" yog tov nrog "inorganics" kom tau hybrid antifreezes. Cov kua yog sib tov ntawm carboxylates thiab inorganic ntsev. Lub sijhawm siv tsis pub dhau 3 xyoos. Ntsuab xim.
- Lobrid
Cov muaj pes tsawg leeg ntawm cov concentrate nyob rau hauv xws li ib tug xws li cov ntxhia reagents thiab organic anti-corrosion additives. Cov yav tas los tsim ib tug nanofilm tshaj tag nrho cov saum npoo ntawm cov hlau, lub tom kawg tiv thaiv tej chaw puas. Lub sijhawm siv mus txog 20 xyoo.
xaus
Lub coolant txo qhov dej khov ntawm cov dej thiab txo cov coefficient ntawm expansion. Cov tshuaj muaj pes tsawg leeg ntawm antifreeze yog ib tug sib tov ntawm distilled dej nrog cawv, thiab kuj muaj xws li corrosion inhibitors thiab dyes.
