Base roj rau automotive engines thiab kis tau tus mob
PAG rau automotive engines thiab transmissions
Raws li hluavtaws cav roj puag, PAG muaj qhov zoo tshaj plaws dispersion, huv si uas muab kev ruaj ntseg kub zoo, lubricity thiab tsis kub fluidity.
Kev sib txhuam coefficient qis tuaj yeem txhim kho roj kev lag luam thiab tiv thaiv kev sib txhuam zoo dua.

Synthetic esters rau automotive engines thiab kis tau tus mob
Tag nrho esterification polyol esters thiab esters, siab purity.
Dissolve fatlute ntawm cov ntxhia roj thiab PAO nyob rau hauv qhov kub thiab txias, txo qhov tso nyiaj thiab zaj duab xis.
Qhov kub viscosity CCS zoo heev tuaj yeem txhim kho kev pib muaj peev xwm ntawm qhov kub thiab txias.
Qhov zoo tshaj plaws tiv thaiv oxidation stability thiab huv si dispersion coj lub neej ntev kev pab cuam.
High polar of low molecular weight design ua tau raws li qhov yuav tsum tau muaj ntawm cov viscosity tsawg thiab ua kom muaj roj ntau tshaj.
Qhov tsis tshua muaj viscosity multi-spec hluavtaws ester muab cov coefficient qis heev thiab lubricity, thiab cov roj hmab zoo sib xws uas tsim nyog rau kev npaj cov tsheb hluav taws xob thiab cov roj xa hluav taws xob.
