Yintoni iMethoxypolyethylene Glycols CAS 9004-74-4?

I-Polyethylene glycol monomethyl ether yimveliso evela kwi-polyethylene glycol. Inyibilika emanzini, kwi-ethanol nakwizona zinyibilikisi ze-polar organic. Ayiguquguquki kangako kune-glycerol, ineempawu zeekhemikhali ezizinzileyo, ayitshisi lula kwaye ayitshatyalaliswa, kwaye inamandla okusebenzisa amanzi. Inoxinzelelo oluphantsi lomphunga kwaye izinzile xa ifudunyezwa. Isetyenziswa njengesithambisi kunye nesithambisi kwishishini lokuprinta nokudaya impahla kunye neshishini leekhemikhali zemihla ngemihla. Kwishishini lezinto zokwakha, isetyenziswa njengezinto eziluhlaza zezixhobo zokunciphisa amanzi zesamente kunye neearhente zokuqinisa. I-polycarboxylic acid enciphisa amanzi esebenza kakuhle eyenziwe kusetyenziswa le nto iluhlaza inamandla okugcina ukusasazeka kwamasuntswana esamente, okwenza imveliso ibe neengenelo zedosi ephantsi, izinga eliphezulu lokunciphisa amanzi, isiphumo esihle sokuqinisa, ukuqina, ukungabikho kokugqwala kweentsimbi zentsimbi kunye nobuhlobo nokusingqongileyo. Ingasetyenziswa kwikhonkrithi yokuthengisa esebenza kakhulu, enamandla aphezulu (C60 okanye ngaphezulu) yokuxuba kwindawo kunye nokuthuthwa komgama omde.
