Ko te Hydroxyethyl cellulose (HEC) he ma, he kowhai marama ranei, he hongi, he kirikiri, he paura totoka kore-paitini, he mea whakarite ma te tauhohenga etherification o te cellulose alkaline me te ethylene oxide (te chlorohydrin ranei).Ko nga etera cellulose wairewa nonionic.Mai i te mea he pai nga ahuatanga o te HEC mo te matotoru, te aukati, te whakamarara, te whakaemulsifying, te honohono, te hanga kiriata, te tiaki i te makuku me te whakarato colloid tiaki, kua whakamahia nuitia i roto i te torotoro hinu, te paninga, te hanga, te rongoa, te kai, te kakano, te hanga pepa me te polymer Polymerization me etahi atu mara.40 reiti tatari mata ≥ 99%;
Te ahua: he ma ki te kowhai marama he kiko, he paura totoka, he kore paitini, he kore reka, he wairewa ki te wai.Kore ki roto i nga whakarewa pararopi noa.
Hydroxyethyl cellulosewhakamaroke
He paku rereke te pokey i te awhe o te uara PH 2-12, engari ka heke te pokey ki tua atu i tenei awhe.Kei a ia nga ahuatanga o te matotoru, te whakatarewa, te here, te whakaemulsifying, te marara, te pupuri i te makuku me te tiaki i te colloid.Ka taea te whakarite otinga i roto i nga awhe pokey rereke.Karekau i raro i te pāmahana me te pehanga noa, karohia te haumākū, te wera me te pāmahana teitei, me te tino pai o te tote wairewa mo nga dielectrics, me tana wairewa wai ka taea e nga tote teitei te noho pumau.
Ngā āhuatanga nui:
I te mea he surfactant kore-katote, kei a hydroxyethyl cellulose nga ahuatanga e whai ake nei hei taapiri atu ki te whakamatotoru, ki te whakatarewa, ki te here, ki te maanu, ki te hanga kiriata, ki te marara, ki te pupuri wai me te whakarato colloid tiaki:
1. He wairewa te HEC i roto i te wai wera, i te wai matao ranei, a kare e pupuhi i te wera nui, i te koropupuputanga ranei, na reira he whanuitanga o te whakarewatanga me nga ahuatanga pokey, me te waiariki kore;
2. Karekau he katote, ka taea te noho tahi me te tini o etahi atu polymers wairewa-wairewa, surfactants, me nga tai.He pai rawa atu te whakamaarata colloidal mo nga otinga electrolyte teitei;
3. Ko te kaha o te pupuri wai he rua te teitei ake o te methyl cellulose, a he pai ake te whakahaere o te rere.
4. Ka whakatauritea ki te methyl cellulose me te hydroxypropyl methyl cellulose, ko te kaha marara o HEC te mea kino rawa atu, engari ko te kaha o te colloid tiaki te kaha.

4. Ka whakatauritea ki te methyl cellulose me te hydroxypropyl methyl cellulose, ko te kaha marara o HEC te mea kino rawa atu, engari ko te kaha o te colloid tiaki te kaha.
Me pehea te whakamahiHEC？
taapiri tika i te wa whakaputa
1. Taapirihia he wai ma ki roto i te peere nui e mau ana ki te whakaranu kutikuti teitei.
2. Me timata ki te whakaoho i te tere iti, ka ata tatari i te hydroxyethyl cellulose ki roto i te otinga.
3. Whakakorikori tonu kia ruku nga matūriki katoa.
4. Kātahi ka tāpirihia he māngai antifungal, tāpiritanga kawakore pēnei i te poaka, he awhina whakamarara, he wai haukini.
5. Oho kia rewa katoa te hydroxyethyl cellulose (ka tino piki ake te pokey o te otinga) i mua i te taapiri i etahi atu waahanga ki roto i te tauira, ka huri kia oti ra ano te hua.
