Tšebeliso ea HPMC Cellulose Ether

HPMC (Hydroxypropyl Methyl Cellulose) ke ether ea cellulose ea meroho. Ke motsoako oa cellulose o se nang ionic oa metsi, o sebelisitsoeng liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang. Ke polymer e feto-fetohang e sebelisoang haholo ho aha, lijo, meriana le lihlahisoa tsa tlhokomelo ea motho. Ka lik'hemik'hale, HPMC ke methyl le hydroxypropyl ethers ea selulose, e entsoeng ka ho arabela selulose ea alkaline ka methyl chloride le propylene oxide.

HPMC ke phofo e tsoeu ho isa ho bosoeu, ha e na monko ebile ha e latsoehe. E qhibiliha metsing a batang empa e ruruhile ka metsing a chesang ho etsa tharollo e hlakileng, e hlakileng. Tharollo ena e ka boela ea etsa ntho e kang gel ha e kopantsoe le motsoako oa saline. HPMC e na le ho boloka metsi a phahameng, viscosity e phahameng le matla a tlamahano, le ts'ebetso e ntle ea sekhomaretsi.

Tšebeliso ea HPMC liindastering tse fapaneng

Kaho

Indastering ea kaho, HPMC e sebelisoa e le motsoako oa bohlokoa ka har'a seretse sa motsoako o omileng, likhomaretsi tsa lithaele, metsoako ea konkreite le lihlahisoa tse thehiloeng ho gypsum. HPMC e eketsa ho boloka metsi le viscosity ho lihlahisoa tse thehiloeng ho samente. E boetse e eketsa ts'ebetso ea lisebelisoa tsa samente ha e ntse e lieha ho beha nako. Ho feta moo, HPMC e ntlafatsa momahano le ho khomarela lirekere tsa motsoako o omileng ka ho fokotsa kotsi ea ho fokotseha le ho fokotseha.

dijo

Baetsi ba lijo ba sebelisa HPMC e le setenya, se tsitsitseng le se emulsifier lijong tse ngata. E ntlafatsa sebopeho le ho lelefatsa sethala sa bophelo ba lijo tse phehiloeng. Har'a lintho tse ling, e ntlafatsa tatso le ponahalo ea lijo tse tlaase tse mafura le tse tlaase. HPMC e boetse e sebelisoa e le moemeli oa ho roala litholoana le meroho ho thibela tahlehelo ea mongobo le ho ntlafatsa ponahalo ea bona.

meriana

Indastering ea meriana, HPMC e sebelisoa haholo e le setlamo, se senyang, se teteaneng le se koahelang. E sebelisoa ho ntlafatsa thepa ea phallo ea phofo, granules le matlapa le ho laola ho lokolloa ha metsoako e sebetsang. HPMC e boetse e sebelisoa ka metsoako ea mahlo hobane ke polima e sa khopiseng le e seng chefo. E sebelisoa haholo ho li-capsules, matlapa, mafura le lihlahisoa tse ling tsa meriana.

tlhokomelo ea botho

HPMC e sebelisoa haholo tlhokomelong ea botho le litlolo e le motenya, emulsifier le stabilizer. E fana ka sebopeho se boreleli le silika ho lotions, litlolo le li-shampoo. E boetse e thusa ho kolobisa letlalo le moriri ka ho fokotsa tahlehelo ea mongobo. HPMC e sebelisana le metsoako e mengata e sebelisoang lihlahisoa tsa tlhokomelo ea motho, e etsa hore e be motsoako o feto-fetohang le o tenyetsehang.

Melemo ea HPMC

Ho na le melemo e mengata ea ho sebelisa HPMC:

• Ho boloka metsi: HPMC e na le pokello e ntle ea metsi, e leng se etsang hore e be se loketseng bakeng sa ho sebelisoa lihlahisoa tsa samente tse kang seretse sa motsoako o omileng.

• Viscosity: HPMC e na le viscosity e phahameng 'me e sebetsa hantle ho matlafatsoa lihlahisoa tse kang lijo, meriana le lihlahisoa tsa tlhokomelo ea motho.

• Matla a Adhesive: HPMC e ntlafatsa matla a ho khomarela lihlahisoa tse kang matlapa le li-capsules indastering ea meriana.

• Thepa e Ntle ea Sekhomaretsi: HPMC e ntlafatsa thepa ea sekhomaretsi ea lihlahisoa tse kang likhomaretsi tsa lithaele.

• Tlhaho e seng ea ionic: HPMC ha e na ionic 'me e ke ke ea sebelisana le li-ion tse ling tsamaisong, ho etsa hore e lumellane le likarolo tse ngata.

Ha re phethela

HPMC ke polymer e tenyetsehang e tenyetsehang e fumaneng lits'ebetso liindastering tse fapaneng. E na le ho boloka metsi ho ikhethang, viscosity e phahameng, matla a tlamo, ho khomarela hantle le lintho tse ling. E sebelisoa haholo mesebetsing ea kaho, lijo, meriana, tlhokomelo ea botho le liindasteri tse ling. Sebopeho sa eona se seng sa ionic se etsa hore se lumellane le mefuta e mengata ea mefuta-futa, e etsa hore e be motsoako o nang le mekhoa e mengata le e bonolo. Ka kakaretso, ts'ebeliso ea HPMC e thusa nts'etsopele ea lihlahisoa tsa pele tse nang le thepa e ntlafalitsoeng le nako e telele ea ho phela.
