Cov polyethers thaiv uas muaj roj ntau Diethylene glycol methyl ethyl ether (DEME) / Dipropylene glycol ether (DPDM)

Nrog cov qauv tshwj xeeb, kev ruaj khov tshuaj lom neeg thiab tsis muaj tshuaj lom,TXHOB HAISFeem ntau yog siv rau hauv kev tsim cov txheej txheem dej, cov kua cwj mem tshwj xeeb thiab cov khoom siv tshwj xeeb. Dhau li ntawm qhov ntawd, nrog kev yaj zoo heev, nws feem ntau siv los tsim cov neeg ntxuav thiab cov tshuaj tshem tawm xim, los rov ua dua thiab rov ua cov khoom siv molecular siab qub.

DPDMyog ib hom tshuaj uas tsis yog ionic, ua haujlwm tau ntau yam thiab zoo rau ib puag ncig nrog kev lom tsawg, cov khoom ua yeeb yaj kiab, hydrophilcity, tsw ntxhiab ether tsis muaj zog, ceev ceev volatile, tshuaj lom neeg ruaj khov zoo, solubility zoo heev, thiab kev nyab xeeb rau tib neeg. Nws yog cais ua Non-HAP / NAP ntsuab solvent hauv Tebchaws Meskas thiab EU. DPDM feem ntau yog siv rau hauv cov dej-raws li thiab curable coatings, tshuaj xws li tshuaj thiab tshuaj tua kab; dav siv hauv cleanser, co-solvent, tshuaj tiv thaiv ntawm cov organic synthesis, additive thiab moistening agent; siv hauv kev lag luam hluav taws xob ua tus neeg sawv cev ntxuav los ntawm kev hloov N-methylpyrrolidone. Tsis tas li ntawd, nws tuaj yeem siv los ua polyurethane.
