I-APEG ne-HPEG (VPEG) ne-TPEG

I-HPEG ayinabo ubuthi, ayicunuli futhi ayincibiliki kahle futhi ngeke ibe yi-hydrolytic. Inokuxubana okuhle nezinhlanganisela eziningi. Kuyinto ebalulekile yokusetshenziswa kwe-ejenti yokunciphisa amanzi ye-polycarboxylate enendawo enhle yokubamba i-dispersibility. Inenzuzo yobuningi bokuxuba okuphansi, izinga eliphezulu lokunciphisa amanzi, umphumela omuhle wokuthuthukisa amandla, ukuqina, ukugqwala kwensimbi ephansi nokuvikelwa kwemvelo. Ingasetshenziswa kukhonkolo yezentengiselwano etholakala ekuthuthweni kwesayithi nokuhamba ibanga elide ngokusebenza okuphezulu nokuqina (ngaphezu kwe-C60).

I-TPEG
1. Ngokuncibilika okuhle kwamanzi, i-TPEG iyancibilika emanzini nasezincibilikiseni ezihlukahlukene zezinto eziphilayo. Kuyimpahla ebalulekile ye-ejenti entsha yokunciphisa amanzi ye-polycarboxylic esebenza kahle kakhulu.
2. Yenziwe nge-catalyst ephezulu esebenzayo ngenqubo ekhethekile yokwenziwa, i-TPEG iwuhlobo lomkhiqizo onesisindo se-molecule encane, i-polyethylene glycol ephansi kanye nezinga eliphezulu lokugcinwa kwamabhondi amabili, okuthuthukisa kakhulu ukusebenza kwe-poly-reaction futhi kwenza izinga lokuguqulwa komkhiqizo libe phezulu. . Isinciphisi samanzi se-Polycarboxylate esihlanganiswe yi-TPEG sinokuqukethwe okuphezulu okusebenzayo nokusebenza okuhle kakhulu okuphelele.
3. I-ejenti yokunciphisa amanzi ye-polycarboxylate ehlanganiswe yi-TPEG inendawo enhle yokuhlakazeka nokubamba. Inenzuzo yokusebenzisa ukhonkolo ophansi, izinga eliphezulu lokunciphisa amanzi, umphumela omuhle wokuthuthukisa amandla, ukuqina kanye nokugqwala kwensimbi ephansi nokuvikelwa kwemvelo.
