Ukuhlangana phakathi kwe-hydroxyethyl cellulose kanye nezingubo ezisuselwa emanzini

Iyini i-hydroxyethyl cellulose?
I-HydroxYethyl Cellulose (HEC), ophuzi noma okhanyayo, okhanyayo, ongenasisekelo, ongewona ubuthi obuqinile, olungiselelwe ukusabela kokuthenjwa kwe-alkaliline cellulose kanye ne-ethylene oxide (noma i-chlorohydrin), ingeyezingane ezincibilikayo ze-cellulose. Njengoba i-HEC inezindawo ezinhle zokuqina, ukumisa, ukusabalalisa, ukubopha, ukubopha amafilimu, ukuvikela umswakama nokunikeza umswakama, ukuhlinzeka ngemithi, ukudla, izindwangu, ukuphawula kwe-polymerization kanye nezinye izinkambu.

I-Hydroxyyethyl cellulose isetshenziswa kabanzi embonini ye-coating, ake sibheke ukuthi isebenza kanjani ezimbobeni:

Kwenzekani lapho i-hydroxyethyl cellulose ihlangana nopende osuselwa emanzini?

Njenge-survic engekho, i-hydroxyyethyl cellulose inezinto ezilandelayo ngokungeziwe, ukumisa, ukubopha, ukuntanta, ukusabalalisa, ukusabalalisa, ukugcinwa kwamanzi kanye nokuhlinzeka ngamanzi nokuhlinzeka ngama-colloid avikelayo:

I-HEC incane emanzini ashisayo noma amanzi abandayo, izinga lokushisa eliphakeme noma elibilayo ngaphandle kwezulu, ukuze libe nobunhlobonhlobo se-soubity kanye ne-viscosity, kanye ne-gelation engeyona eyeshisayo;

Umthamo wokugcina amanzi uphakeme kabili njenge-methyl cellulose, futhi inomthethonqubo ongcono wokugeleza;

Akukona-ionic futhi kungahle kube nobubanzi obuningi bakwamanye ama-polymers ancibilikayo, ama-surfactants, nosawoti. Kungumkhulu we-colloidal omkhulu omuhle kakhulu wezixazululo 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.

Njengoba i-hydroxyyethylyl ephethwe ingaphezulu i-hydroxyethyls iqinile noma i-fibrous swolid, amaphuzu alandelayo kufanele alandelwe lapho ulungiselela i-hydroxyethyyl cellulose mama makeome:

(1) Ngaphambi nangemva kokungeza i-hydroxyethyl cellulose, kufanele ivuswe ngokuqhubekayo kuze kube yilapho isixazululo sisobala futhi sicacile.
(2) Kumele ibonakale kancane ethangini lokuxuba, futhi ungafaki inani elikhulu noma faka ngqo i-hydroxyethyl cellulose ethangini lokuxuba.
(3) Izinga lokushisa lamanzi nenani le-PH emanzini linobudlelwano obukhulu nokuchithwa kwe-hydroxyethyl cellulose, ngakho-ke kufanele kukhokhwe.
(4) Ungangezi ezinye izinto ze-alkali ngayinye kwingxube ngaphambi kwe-hydroxyethyl cellulose powder ifakwe emanzini. Ukuphakamisa i-PH ngemuva kokumanzisa kusiza ukuncibilikisa.
(5) Ngokunokwenzeka, engeza i-antifungal ejenti kusengaphambili.
(6) Uma usebenzisa i-high-viscoxyyethyl celtule
