Ukuhlangana kwe-Hydroxyethyl cellulose kanye nezingubo ezisuselwa emanzini

Iyini i-hydroxyethyl cellulose?

I-Hydroxyyethyl celtulose (HEC), i-White noma ephuzi, engenasiphepho, engenangqondo, eqinile eqinile, elungiselelwe yi-alkaline cellulose ne-ethylene oxide (noma i-chlorohydrin), i-genunes ancition pullule cellulose asher. Ngoba i-HEC inezindawo ezinhle njengokuqina, ukumisa, ukusabalalisa, ukubopha, ukubopha amafoldi, ukuvikela umswakama nokuhlinzeka ngemiswa, kusetshenziswe kalula ekuhlolweni kwamafutha, izindwangu, ukwakhiwa kwemithi kanye nama-polymer. Polymerization kanye nezinye izinkambu.

I-Hydroxyyethyl cellulose isetshenziswa kabanzi embonini yezambatho. Ake sibheke ukuthi isebenza kanjani ezimbobeni:

Kwenzekani lapho i-hydroxyethyl cellulose ihlangana nezingubo ezisuselwa emanzini?

Njenge-exfractant engeyona eye-ionic, i-hydroxyyethyl cellulose inezinto ezilandelayo ngokungeziwe, ukumisa, ukubopha, ukukhishwa, ukugcinwa kwamafilimu, ukugcinwa kwamanzi, ukugcinwa kwamanzi kanye nokuhlinzeka ngokuvikela ama-colloids:

I-HEC incane emanzini ashisayo noma abandayo, futhi ayinqamuleli ekushiseni okuphezulu noma ukubilisa, okwenza kube nohlu oluningi lwe-soubity kanye ne-viscosity, kanye nokugugulwa okungeyona okushisayo;

Umthamo wokugcinwa kwamanzi kabili lokho ku-methyl cellulose, futhi kunemithetho engcono yokugeleza;

Okungeyona i-ionic ngokwayo ingahlangana nebanga lamanye ama-polymers ancibilikisiwe amanzi, ama-surfactants, kanye nosawoti, futhi kungumkhulu we-colloidal, futhi ungumkhulu kakhulu we-colloidal oqukethe izixazululo eziphakeme ze-electrolyte;

Uma kuqhathaniswa ne-methyl cellulose ye-methyl ne-hydroxypropyll methyl celtule, amandla asabalalisayo ka-HEC yiyona ebi kakhulu, kepha ikhono elivikelayo le-collroid linamandla kakhulu.

Kusukela i-Hydroxyyethylll ephethwe yi-HeldroxYethyl i-powdery noma i-fibrous swolid, uShandong Heda akukhumbuza ukuthi unake amaphuzu alandelayo lapho ulungiselela i-Hydroxyethyyl cellulose makeome wotshwala:

(1) Ngaphambi nangemva kokungeza i-hydroxyethyl cellulose, kufanele igcinwe ivuselelwa kuze kube yilapho isixazululo sisobala futhi sicacile.

.

(3) Izinga lokushisa lamanzi nenani le-PH lamanzi linobudlelwano obusobala bokuchithwa kwe-hydroxyethyl cellulose, ngakho-ke kufanele kukhokhwe kuwo.

(4) Ungalokothi ungeze ezinye izinto ze-alkali ngayinye engxube ngaphambi kwe-hydroxyethyl cellulose powder ifakwe emanzini. Ukuphakamisa i-PH kuphela ngemuva kokumanzisa kuzosiza ekuqothulweni.

(5) Ngokunokwenzeka, engeza i-antifungal ejenti kusengaphambili.
