Hydroxypropyl Methyl Cellulose eo hangata e tsejoang ka hore ke Hypromellose, HPMC, ke selulose sa ether se sa sebetseng sa ionic se nkiloeng ho lipolymer tsa tlhaho joalo ka k'hothone e hloekisitsoeng kapa makhasi a patsi ka letoto la lits'ebetso tsa lik'hemik'hale. E hlahisa phofo e tšoeu e sa nkheng, e seng chefo, e sa latsoeheng. Sehlahisoa sena se qhibiliha habonolo ka metsing a chesang le a batang, se etsa tharollo e hlakileng ea viscous e nang le mefuta e fapaneng ea thepa, e etsa hore e batloe haholo bakeng sa lits'ebetso tse fapaneng.

HPMC e na le litšobotsi tse ikhethang tse kang ho tenya ho hoholo, ho tlama, ho qhalakanya, ho etsa emulsifying, ho etsa filimi, ho emisa, ho bapatsa, ho etsa gelling, ho sebetsa ka holim'a metsi, ho boloka metsi le ho sireletsa thepa ea colloid. Ts'ebeliso ea eona e atileng ho pholletsa le liindasteri tse kenyelletsang kaho, meriana, lijo, PVC, lirafshoa, le lihlahisoa tsa tlhokomelo ea motho / lapeng.

Lintho tse akaretsang tsa HPMC ke life?

tlhaloso2

Hydroxypropyl Methylcellulose (HPMC) ke motsoako oa selulose o nang le mefuta e mengata ea thepa e etsang hore e sebelisoe liindastering tse fapaneng. Lintlha tse akaretsang tsa HPMC ke tsena:

Sebopeho sa Lik'hemik'hale:

HPMC ke semi-synthetic polymer e nkiloeng ho selulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela.

Sebopeho sa lik'hemik'hale sa HPMC se kenyelletsa lihlopha tsa hydroxypropyl le methyl tse khomaretsoeng mokokotlong oa cellulose.

Sollubility:

HPMC e qhibiliha ka metsing, e etsa tharollo e hlakileng, e etsang hore ho be bonolo ho kenyelletsa metsoako ea metsi.

Viscosity:

E 'ngoe ea thepa ea bohlokoa ea HPMC ke bokhoni ba eona ba ho fetola viscosity. E ka fana ka thickening ho litharollo le metsoako, ho kenya letsoho ho ntlafatsa sebopeho le ho sebetsa.

Ho Etsa Lifilimi:

HPMC e na le thepa ea ho etsa lifilimi, e etsang hore e be molemo lits'ebetsong moo ho hlokahalang filimi e sireletsang kapa e kopanetsoeng.

Thermal Gelation:

HPMC e bonts'a gelation ea mocheso, ho bolelang hore viscosity ea eona e eketseha ka mocheso. Hangata thepa ena e sebelisoa mefuteng e laoloang ea tokollo ea lithethefatsi.

Mosebetsi oa Bokaholimo:

HPMC e ka ba le thepa e kang surfactant, e matlafatsang emulsification le ho hasana mefuteng e itseng.

Botsitso:

HPMC tlatsetsa botsitso ba suspensions, emulsions, le formulations tse ling ka ho thibela phatsa ho rarolla kapa karohano.

Paballo ea Metsi:

HPMC e na le bokhoni ba ho boloka metsi, e etsa hore e be ea bohlokoa lits'ebetsong moo ho boloka mongobo ho hlokahalang, joalo ka thepa ea kaho.

Ho khomarela:

Liindastering tse fapa-fapaneng, HPMC e ntlafatsa ho khomarela, ebang ke ka thepa ea kaho e kang seretse kapa lirapeng le likhomaretsi.

Inertness ea lik'hemik'hale:

HPMC ke inert ea lik'hemik'hale, ho bolelang hore ha e sebetsane le likarolo tse ling ha li etsoa, ho netefatsa botsitso le ho lumellana le mefuta e mengata ea lisebelisoa.

pH Sensitivity:

Thepa ea HPMC e ka susumetsoa ke pH ea tharollo kapa sebopeho. Ka kakaretso e tsitsitse ho feta pH e pharaletseng.

Ho tsitsa ha Mocheso:

HPMC e nkuoa e ka senyeha, e ka bang molemo lits'ebetsong tse itseng tsa tikoloho le tse tšoarellang.

Thepa ena e akaretsang e etsa hore HPMC e be polymer e feto-fetohang le e sebelisoang haholo liindastering tse kang tsa meriana, kaho, lijo, litlolo, le tse ling. Bokhoni ba eona ba ho fetola thepa ea rheological le ea ts'ebetso ea metsoako e tlatsetsa ho sebetsa ha eona ka bophara.
