Hydroxypropyl cellulose (HPC) ke motsoako oa selulose, e leng polima ea tlhaho e fumanehang maboteng a lisele tsa limela.Leha ho le joalo, le hoja selulose ka boeona e le ea tlhaho, mokhoa oa ho e fetola ho etsa hydroxypropyl cellulose e kenyelletsa lik'hemik'hale, tse lebisang ho semi-synthetic material.
1. Tšimoloho ea Tlhaho ea Cellulose:
Cellulose ke polymer e ngata ka ho fetisisa lefatšeng 'me ke karolo ea bohlokoa ea marako a lisele tsa limela, e fanang ka tšehetso ea meralo.E fumaneha ka bongata mehloling e kang patsi, k'hothone, hemp, le lisebelisoa tse ling tsa semela.Ka lik'hemik'hale, cellulose ke polysaccharide e nang le likarolo tsa tsoekere tse hokahaneng hammoho ka liketane tse telele.
2. Mokhoa oa Tlhahiso ea Hydroxypropyl Cellulose:
Hydroxypropyl cellulose e entsoe ka selulose ka mokhoa oa ho fetola lik'hemik'hale.Sena se kenyelletsa ho phekola cellulose ka propylene oxide tlas'a maemo a laoloang.Boitšoaro bo fella ka ho nkeloa sebaka ha lihlopha tsa hydroxyl ka har'a molek'hule ea selulose ka lihlopha tsa hydroxypropyl, tse hlahisang hydroxypropyl cellulose.
Ts'ebetso ena hangata e kenyelletsa mehato e mengata, ho kenyelletsa etherification, tlhoekiso le ho omisa.Le hoja thepa ea ho qala, cellulose, e le ea tlhaho, phekolo ea lik'hemik'hale e amehang tlhahisong ea hydroxypropyl cellulose e etsa hore e be semi-synthetic.
3. Lintho tsa Hydroxypropyl Cellulose:
Hydroxypropyl cellulose e na le lintho tse 'maloa tse molemo, ho kenyelletsa:
Sollubility: E qhibiliha mefuteng e mengata ea lihlapolli, ho kenyeletsoa metsi, ethanol, le metsoako e meng ea tlhaho.
Ho etsa lifilimi: E ka sebelisoa ho etsa lifilimi tse tšesaane tse nang le thepa e ntle ea mochini.
Thickening agent: Hangata e sebelisoa e le ntho e etsang hore e be motenya lits'ebetsong tse fapaneng, joalo ka meriana, litlolo le lihlahisoa tsa lijo.
Botsitso: E bonts'a botsitso bo botle ba mocheso le lik'hemik'hale, e etsa hore e loketse ho sebelisoa libakeng tse fapaneng.
Khokahano: E lumellana le lisebelisoa tse ling tse ngata, e lumellang lits'ebetso tse fapaneng.
4. Lisebelisoa tsa Hydroxypropyl Cellulose:
Hydroxypropyl cellulose e fumana lits'ebetso ho liindasteri tse fapaneng:
Indasteri ea Litlhare: E sebelisoa haholo joalo ka setlamo, sa pele sa filimi, se teteaneng, le se tsitsitseng mefuteng ea meriana, ho kenyeletsoa matlapa, li-capsules le li-topical formulations.
Indasteri ea Litlolo: E sebelisoa ho litlolo le lihlahisoa tsa tlhokomelo ea motho e le ntho e matlafatsang, e tsitsitseng, le filimi ea pele lihlahisoa tse kang litlolo, litlolo le lihlahisoa tsa tlhokomelo ea moriri.
Indasteri ea Lijo: Indastering ea lijo, e sebelisoa e le setei, se tsitsitseng, le emulsifier lihlahisoa tse kang li-sauces, li-dressings le li-dessert.
Lisebelisoa tsa Indasteri: E fumana ts'ebeliso lits'ebetsong tsa indasteri joalo ka liphahlo, likhomaretsi, le lifilimi tse ikhethileng ka lebaka la thepa ea eona ea ho etsa lifilimi le sekhomaretsi.
5. Mehopolo Malebana le Tlhaho:
Le hoja hydroxypropyl cellulose e tsoa ho selulose, e leng ntho ea tlhaho, ts'ebetso ea phetoho ea lik'hemik'hale e amehang tlhahisong ea eona e hlahisa lipotso mabapi le tlhaho ea eona.Le hoja e qala ka polima ea tlhaho, ho eketsoa ha lihlopha tsa hydroxypropyl ka liphetoho tsa lik'hemik'hale ho fetola sebopeho le thepa ea eona.Ka lebaka leo, hydroxypropyl cellulose e nkoa e le semi-synthetic ho fapana le ea tlhaho feela.
Hydroxypropyl cellulose ke lisebelisoa tse ngata tse tsoang ho selulose, polymer ea tlhaho e fumanoang limela.Leha ho le joalo, tlhahiso ea eona e kenyelletsa phetoho ea lik'hemik'hale, e leng se hlahisang semi-synthetic material.Leha ho le joalo, hydroxypropyl cellulose e boloka thepa e ngata e molemo mme e fumana lits'ebetso tse fapaneng ho tsa meriana, litlolo, lihlahisoa tsa lijo le lits'ebetsong tsa indasteri.Ho utloisisa tšimoloho ea eona ea tlhaho le ts'ebetso ea tlhahiso ho bohlokoa haholo bakeng sa ho lekola ho tšoaneleha ha eona bakeng sa lits'ebetso tse fapaneng le ho rarolla mathata a amanang le tlhaho ea eona.
