1. Thepa ea hydroxyethyl cellulose
Sehlahisoa sena se na le 'mala o mosoeu kapa o mosehla o mosehla o sa nkhang hamonate ebile o phalla habonolo, 40 mesh sieve rate ≥99%; mocheso o bonolo: 135-140 ° C; boima bo bonahalang: 0.35-0.61g / ml; mocheso oa ho senyeha: 205-210 ° C; lebelo le tukang Butle; tekano mocheso: 23 ° C; 6% ho 50%rh, 29% ho 84%rh.
E qhibiliha ka metsing a batang le metsing a chesang, 'me ka kakaretso ha e qhibilihe ka har'a metsoako e mengata ea tlhaho. The viscosity e fetoha hanyenyane ho palo ea PH ea 2-12, empa viscosity e fokotseha ho feta mefuta ena.
2. Lintho tsa bohlokoa
Joalo ka motho ea se nang ionic,hydroxyethyl cellulosee na le lintho tse latelang ho kenyelletsa ho teteaneng, ho emisa, ho tlama, ho phaphamala, ho etsa filimi, ho qhalakanya, ho boloka metsi le ho fana ka colloid e sireletsang:
1. HEC e qhibiliha ka metsing a chesang kapa a batang, 'me ha e chese ka mocheso o phahameng kapa ho belisoa, e leng se etsang hore e be le mefuta e mengata ea ho qhibiliha, litšoaneleho tsa viscosity le gelation e sa chesang.
2. Ha e na ionic 'me e ka phela hammoho le mefuta e mengata e mengata ea li-polymers tse qhibilihang ka metsing, li-surfactants, le letsoai. Ke colloidal thickener e babatsehang bakeng sa tharollo ea electrolyte e phahameng haholo.
3. Matla a ho boloka metsi a phahame ka makhetlo a mabeli ho feta a methyl cellulose, 'me a na le taolo e ntle ea ho phalla.
4. Ha e bapisoa le methyl cellulose e tsejoang le hydroxypropyl methyl cellulose, HEC e na le bokhoni bo bobe ka ho fetisisa ba ho qhalakanngoa, empa e na le matla a matla a tšireletso a colloid.
3. Tšebeliso ea hydroxyethyl cellulose
Ka kakaretso e sebelisoa e le li-thickeners, li-agent tse sireletsang, li-adhesives, stabilizers le li-additives bakeng sa ho lokisa li-emulsion, li-jellies, mafura, litlolo, lihloeki tsa mahlo, li-suppositories le matlapa, hape li sebelisoa e le li-gels tsa hydrophilic, lisebelisoa tsa skeleton, e ka sebelisoa ho lokisa matrix- thaepa litokisetso tsa tokollo e tsitsitseng, hape e ka sebelisoa e le mokhoa o tsitsitseng oa lijo.
