Stability thiab Reactivity
Peb Propylene Glycol Monoethyl Ether (PGME) yog cov kuab tshuaj purity siab uas yog tus nqi sib tw. Nws yog cov kua tsis muaj xim uas tsis muaj ntxhiab tsw thiab tau siv dav hauv ntau yam lag luam, suav nrog cov txheej txheem, inks, thiab tshuaj ntxuav. Nws qib purity siab thiab tus nqi qis ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov lag luam tab tom nrhiav kev txhim kho lawv cov txheej txheem ntau lawm yam tsis muaj kev cuam tshuam rau qhov zoo.
Propylene Glycol Monoethyl Ether (PGME) yog cov kua tsis muaj xim, tsis muaj ntxhiab tsw, tsis muaj volatility thiab kub kub. Nws yog cov kuab tshuaj ntau yam uas tau siv dav hauv ntau qhov kev lag luam, nrog rau cov txheej txheem, inks, thiab tshuaj ntxuav. Peb PGME yog los ntawm cov neeg muab kev ntseeg siab thiab muaj kev purity siab, nrog rau qib purity yam tsawg kawg nkaus ntawm 99.5%.
Ib qho txiaj ntsig tseem ceeb ntawm peb PGME yog nws qib purity siab. Qhov no ua kom ntseeg tau tias peb PGME tsis pub dawb los ntawm impurities uas tuaj yeem cuam tshuam qhov zoo ntawm koj cov khoom. Tsis tas li ntawd, peb PGME yog tus nqi sib tw, ua rau nws muaj txiaj ntsig zoo rau koj cov kev xav tau hnyav.
Hais txog cov ntawv thov, PGME tau siv dav los ua cov kuab tshuaj hauv kev tsim cov txheej, inks, thiab tshuaj ntxuav. Nws tsis tshua muaj volatility thiab kub kub taw tes ua rau nws ib tug zoo tagnrho hnyav rau high-temperature daim ntaub ntawv. Tsis tas li ntawd, nws muaj peev xwm yaj ntau yam ntawm cov organic tebchaw ua rau nws muaj ntau yam hnyav hnyav uas tuaj yeem siv rau ntau yam kev lag luam.
Lwm qhov zoo ntawm peb cov PGME yog nws cov ntxhiab tsw qab, uas ua rau nws muaj cov kuab tshuaj zoo dua los ua haujlwm nrog rau lwm cov kuab tshuaj uas muaj ntxhiab tsw. Qhov no tuaj yeem txhim kho kev nyab xeeb ntawm chaw ua haujlwm thiab tag nrho cov neeg ua haujlwm txaus siab.
