Thepa ea 'mele ea Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ke polima e qhibilihang ka metsing e tsoang ho selulose. E sebelisoa haholo liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang ea 'mele. Tse ling tsa likarolo tsa bohlokoa tsa 'mele tsa hydroxyethyl cellulose li kenyelletsa:

1. Solubility: HEC e qhibiliha ka metsing 'me e etsa litharollo tse hlakileng, tse hlakileng. Ho qhibiliha ha HEC ho ka fapana ho itšetlehile ka lintlha tse kang tekanyo ea ho fetola (DS) ea lihlopha tsa hydroxyethyl le boima ba molek'hule ea polymer.
2. Viscosity: HEC e bonts'a viscosity e phahameng ka tharollo, e ka lokisoang ke lintlha tse fapaneng tse kang mahloriso a polymer, mocheso le sekhahla sa ho kuta. Litharollo tsa HEC hangata li sebelisoa e le li-thickening agents mefuteng e mengata ea likopo, ho kenyelletsa le lipente, li-adhesives, le lihlahisoa tsa tlhokomelo ea motho.
3. Bokhoni ba ho Etsa Lifilimi: HEC e na le bokhoni ba ho etsa lifilimi tse feto-fetohang le tse momahaneng ha li omisoa. Thepa ena e sebelisoa lits'ebetsong tse kang ho roala matlapa le li-capsules tsa meriana, hammoho le litlolo le lihlahisoa tsa tlhokomelo ea motho.
4. Ho Boloka Metsi: HEC e na le thepa e ntle ea ho boloka metsi, e e etsa polima e sebetsang hantle e qhibilihang ka metsing bakeng sa ho sebelisoa linthong tsa kaho tse joalo ka seretse, li-grouts le renders. E thusa ho thibela tahlehelo ea metsi ka potlako nakong ea ho kopanya le ho sebelisoa, ho ntlafatsa ts'ebetso le ho khomarela.
5. Thermal Stability: HEC e bonts'a botsitso bo botle ba mocheso, e boloka thepa ea eona ho feta mefuta e mengata ea mocheso. E khona ho mamella mocheso o sebetsanang le ona liindastering tse fapaneng ntle le ho senyeha ho hoholo.
6. pH botsitso: HEC e tsitsitse ho feta mefuta e mengata ea pH, e etsa hore e loketse ho sebelisoa ha ho etsoa lihlahisoa tse nang le acidic, neutral, kapa alkaline. Thepa ena e e lumella ho sebelisoa lits'ebetsong tse fapaneng ntle le ho tšoenyeha ka ho senyeha ho amanang le pH.
7. Ho lumellana: HEC e lumellana le mefuta e mengata ea lisebelisoa tse ling, ho kenyelletsa le letsoai, li-acids le li-solvents tsa tlhaho. Tšebelisano ena e lumella ho etsoa ha litsamaiso tse rarahaneng tse nang le thepa e hlophisitsoeng liindastering tse kang tsa meriana, tlhokomelo ea botho, le kaho.
8. Biodegradability: HEC e nkiloe mehloling e ka nchafatsoang joalo ka makhasi a patsi le k'hothone, e leng se etsang hore e senyehe le ho baballa tikoloho. Hangata e ratoa ho feta li-polymer tsa maiketsetso lits'ebetsong moo ts'ebetso e leng taba.

thepa ea 'mele ea hydroxyethyl cellulose (HEC) e etsa hore e be tlatsetso ea bohlokoa liindastering tse fapa-fapaneng, moo e tlatsetsang ts'ebetsong, botsitso le ts'ebetsong ea lihlahisoa tse ngata le lihlahisoa.
