APEG uye HPEG (VPEG) uye TPEG

HPEG haina-chepfu, isingatsamwise nekunyungudika kwemvura kwakanaka uye haizove hydrolytic deteriorated. Iyo ine yakanaka intermiscibility nemakomisheni akawanda. Iyo yakakosha zvinhu zvakabikwa zvepolycarboxylate mvura yekudzikisa mumiririri ine yakanaka dispersibility inobata nzvimbo. Iyo ine mukana weiyo yakaderera kusanganisa huwandu, yakakwira yekudzikisa mvura mwero, yakanaka simba rekusimudzira maitiro, kusimba, yakaderera simbi corrosion uye kuchengetedzwa kwezvakatipoteredza. Inogona kushandiswa mukongiri yekutengeserana iyo inowanikwa kune-site inokurudzira uye kutakura kure kure nekufambisa kwepamusoro uye kusimba (pamusoro peC60).

TPEG
1. Nekunyungudika kwemvura kwakanaka, TPEG inonyungudika mumvura uye zvakasiyana-siyana zvinonyungudutsa. Icho chinhu chakakosha mbishi yezvinhu zvitsva zvepolycarboxylic yakakwirira-inoita yekudzikisa mvura mumiririri.
2. Yakagadzirwa kubva kune yakakwirira inoshanda catalyst kuburikidza neakakosha maitiro ekugadzira, TPEG rudzi rwechigadzirwa chine huremu hwakatetepa hwema molecular, yakaderera polyethylene glycol uye yakakwirira retention rate yemabhondi maviri, ayo anovandudza zvakanyanya activation yepoly-reaction uye inoita kuti chigadzirwa cheshanduko chiwedzere. . Polycarboxylate mvura-inodzikisira yakasanganiswa neTPEG ine yakakwira inoshanda zvemukati ine yakanakisa kuzadza kuita.
3. Iyo polycarboxylate mvura yekudzikisa mumiririri yakagadzirwa neTPEG ine yakanaka dispersibility uye inobata nzvimbo. Iyo ine mukana weiyo yakaderera kongiri kushandiswa, yakakwira yekudzikisa mvura mwero, yakanaka simba rekusimudzira maitiro, kusimba uye nekushomeka kwesimbi uye kuchengetedzwa kwezvakatipoteredza.
