Hydroxypropyl methylcellulose (Hypromellose)

Hydroxypropyl methylcellulose (Hypromellose)

Hydroxypropyl Methylcellulose (HPMC) e boetse e tsejoa haholo ka lebitso la lebitso la Hypromellose. Hypromellose ke lebitso leo e seng la mong'a lona le sebelisetsoang ho bolela polymer e tšoanang maemong a meriana le a bongaka. Tšebeliso ea lentsoe "Hypromellose" e atile indastering ea meriana 'me ha e le hantle e tšoana le HPMC.

Mona ke lintlha tsa bohlokoa mabapi le Hydroxypropyl Methylcellulose (Hypromellose):

  1. Sebopeho sa Lik'hemik'hale:
    • HPMC ke semi-synthetic polymer e nkiloeng ho selulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela.
    • E hlahisoa ke cellulose e fetolang lik'hemik'hale ka ho eketsoa ha lihlopha tsa hydroxypropyl le methyl.
  2. Lisebelisoa:
    • Meriana: Hypromellose e sebelisoa haholo indastering ea meriana e le thuso. E fumaneha ka mefuta e fapaneng ea litekanyetso tsa molomo, ho kenyelletsa matlapa, li-capsules le li-suspension. Hypromellose e sebetsa e le setlamo se kopanyang, se senyang, se fetolang viscosity, le filimi ea pele.
    • Indasteri ea Kaho: E sebelisoa lihlahisoa tse kang likhomaretsi tsa lithaele, seretse le lisebelisoa tse thehiloeng ho gypsum. E matlafatsa ts'ebetso, ho boloka metsi, le ho khomarela.
    • Indasteri ea Lijo: E sebetsa e le setenya, se tsitsisa, le emulsifier lihlahisoa tsa lijo, e tlatsetsang sebopeho le botsitso.
    • Litlolo le Lihlahisoa tsa Tlhokomelo ea Motho: E fumanoa ka litlolo, litlolo, le litlolo bakeng sa ho tenya le ho tsitsisa ha eona.
  3. Thepa ea Sebele:
    • Ka tloaelo ke phofo e tšoeu ho isa ho e mosoeu ka sebopeho sa fibrous kapa granular.
    • Ha e na monko ebile ha e latsoehe.
    • E qhibiliha ka metsing, ho etsa tharollo e hlakileng le e se nang mebala.
  4. Mekhahlelo ea ho fetola:
    • Mefuta e fapaneng ea Hypromellose e kanna ea ba le maemo a fapaneng a ho nkela sebaka, e amang thepa e joalo ka ho qhibiliha le ho boloka metsi.
  5. Tšireletseho:
    • Ka kakaretso e nkoa e sireletsehile bakeng sa tšebeliso ea meriana, lijo, le lihlahisoa tsa tlhokomelo ea botho ha li sebelisoa ho latela litataiso tse behiloeng.
    • Mehopolo ea polokeho e ka ipapisa le lintlha tse joalo ka tekanyo ea phetoho le ts'ebeliso e ikhethileng.

Ke habohlokoa ho hlokomela hore ha ho buisanoa ka HPMC tabeng ea meriana, lentsoe "Hypromellose" le sebelisoa hangata. Tšebeliso ea lentsoe leha e le efe ea amoheleha, 'me e bua ka polima e tšoanang e nang le hydroxypropyl le methyl substitutes mokokotlong oa cellulose.
