Methoxypolyethylene Glycols CAS 9004-74-4

Polyethylene glycol monomethyl ether yog ib qho khoom siv los ntawm polyethylene glycol. Nws yaj tau hauv dej, ethanol thiab feem ntau cov kuab tshuaj organic polar heev. Nws tsis tshua muaj zog dua li glycerol, muaj cov khoom siv tshuaj ruaj khov, tsis yooj yim hydrolyzed thiab puas tsuaj, thiab muaj zog hydrophilicity. Nws muaj lub zog vapor qis thiab ruaj khov rau cua sov. Nws yog siv los ua cov khoom ua kom tuab thiab roj nplua nyeem hauv kev lag luam luam ntawv thiab zas xim thiab kev lag luam tshuaj txhua hnub. Hauv kev lag luam khoom siv hauv tsev, nws yog siv los ua cov khoom siv raw rau cov cement dej reducers thiab cov neeg sawv cev txhawb zog. Cov polycarboxylic acid high-efficiency dej reducer synthesized siv cov khoom siv raw no muaj peev xwm zoo los khaws cov khoom sib xyaw ntawm cov cement, ua rau cov khoom muaj qhov zoo ntawm cov tshuaj tsawg, cov dej txo qis siab, cov nyhuv txhawb zog zoo, ruaj khov, tsis muaj xeb ntawm cov hlau thiab kev phooj ywg ib puag ncig. Nws tuaj yeem siv rau hauv kev ua haujlwm siab, muaj zog siab (C60 lossis siab dua) kev lag luam concrete rau kev sib tov hauv qhov chaw thiab kev thauj mus los ntev.
