Yintoni iMethoxypolyethylene Glycols CAS 9004-74-4?

Ipolyethylene glycol monomethyl ether iphuma kwipolyethylene glycol. Inyibilika emanzini, i-ethanol kunye nezona zinyibiliki ziphezulu zepolar eziphilayo. Ayinakuguquka ngaphantsi kwe-glycerol, ineekhemikhali ezizinzile, ayifuni i-hydrolyzed kwaye itshatyalaliswe, kwaye ine-hydrophilicity enamandla. Inoxinzelelo lomphunga oluphantsi kwaye izinzile ukutshisa. Isetyenziswa njenge-thickener kunye ne-lubricant kwishishini lokuprinta kunye nokudaya kunye neshishini lemihla ngemihla lemichiza. Kwishishini lezinto zokwakha, lisetyenziswa njengento ekrwada kwizinciphisi zamanzi zesamente kunye neearhente zokuqinisa. I-polycarboxylic acid ephezulu esebenza ngokufanelekileyo isinciphisi samanzi esenziwe kusetyenziswa le mathiriyeli ekrwada inamandla okuqina okugcina ukusasazeka kwamasuntswana esamente, okwenza imveliso ibe nezibonelelo zedosi ephantsi, izinga eliphezulu lokunciphisa amanzi, isiphumo esihle sokomeleza, ukuqina, akukho ukubola kwentsimbi. imivalo kunye nobuhlobo bendalo. Ingasetyenziselwa ukusebenza okuphezulu, amandla aphezulu (i-C60 okanye ngaphezulu) ikhonkrithi yezorhwebo yokuxuba kwisayithi kunye nokuthutha okude.

Isicelo

I-Methoxypolyethylene glycols esetyenziswa njenge-thickener kunye ne-lubricant kushicilelo lwelaphu kunye neshishini lokudaya kunye neshishini lemihla ngemihla lemichiza. Isetyenziswa njengemathiriyeli ekrwada yesinciphisi samanzi sesamente kunye nearhente yokuqinisa kwishishini lezinto zokwakha.
