HPMC, kapa hydroxypropyl methylcellulose, ke polymer e feto-fetohang e nkiloeng ho cellulose, ntho ea tlhaho e fumanoang maboteng a sele ea limela. Lisebelisoa tse thehiloeng ho HPMC li hapile tlhokomelo e kholo liindastering tse fapaneng ka lebaka la thepa ea tsona e ikhethang le mefuta e mengata ea ts'ebeliso.
Selelekela ho HPMC:
Hydroxypropyl methylcellulose (HPMC) ke polymer e entsoeng ka halofo, e qhibilihang ka metsing e nkiloeng ho cellulose. E atisa ho sebelisoa e le seteishene sa ho teteana, se kopanyang, se kopanyang le se etsang filimi liindastering tse fapaneng, ho kenyeletsoa meriana, lijo, kaho, litlolo le lihlahisoa tsa tlhokomelo ea botho.
Litšobotsi tsa Lisebelisoa tse thehiloeng ho HPMC:
Ho qhibiliha ha metsi: HPMC e na le ho qhibiliha ho babatsehang ha metsi, e leng se etsang hore e lokele ho sebelisoa litharollong le mefuteng ea metsi.
Taolo ea Viscosity: E sebetsa e le sesebelisoa se sebetsang sa ho tenya, se lumellang taolo e nepahetseng holim'a viscosity ea litharollo le metsoako.
Matlotlo a ho Etsa Filimi: HPMC e ka etsa lifilimi tse hlakileng, tse tenyetsehang ha e omisitsoe, e leng se etsang hore e be molemo ho koaheleng, lifiliming le litsamaisong tsa ho fana ka meriana e laoloang.
Botsitso: Lisebelisoa tse thehiloeng ho HPMC li fana ka botsitso bo botle holim'a mefuta e mengata ea pH le maemo a mocheso.
Ho bola ha lintho tse phelang: Kaha e tsoa ho cellulose, HPMC e bola ha lintho tse phelang, e leng se etsang hore e be mosa tikolohong ha e bapisoa le li-polymer tsa maiketsetso.
3. Dikopo tsa Disebediswa tse thehilweng ho HPMC:
(1) Meriana:
Tlhahiso ea Matlapa: HPMC e sebelisoa haholo e le ntho e kopanyang le e arohanang mefuteng ea matlapa, e fanang ka tokollo e laoloang le ntlafatso ea ho qhibiliha ha meriana.
Metswako ea ho Hlahisa: E sebelisoa ka har'a mafura, litlolo le li-gel e le sesebelisoa sa ho fetola viscosity le emulsifier.
Mekhoa ea ho Lokolla e Laoloang: Li-matrices tse thehiloeng ho HPMC li sebelisoa litsamaisong tsa ho lokolla lithethefatsi tse tsoelang pele le tse reretsoeng ho fana ka lithethefatsi.
(2) Indasteri ea Lijo:
Sesebediswa sa ho Tetefatsa: HPMC e sebedisetswa ho tentsha le ho tsitsisa dijo tse kang disoso, sopho le dijo tse monate.
Ho Nkela Mafura Sebaka: E ka sebelisoa e le ntho e nkang sebaka sa mafura lijong tse nang le mafura a fokolang kapa tse se nang mafura ho ntlafatsa sebopeho le maikutlo a molomo.
(3) Kaho:
Disemethara le Disemethara: HPMC e ntlafatsa bokgoni ba ho sebetsa, ho kgomarela, le ho boloka metsi ka hara disemethara le disemethara tse thehilweng samente.
Likhomaretsi tsa Lithaele: Li eketsa matla a ho kopanya le nako ea ho buleha ha likhomaretsi tsa lithaele, li ntlafatsa ts'ebetso ea tsona.
(4) Litlolo le Tlhokomelo ea Motho ka Mong:
Lihlahisoa tsa Tlhokomelo ea Moriri: HPMC e kenyelelitsoe ka har'a li-shampoo, li-conditioner le lihlahisoa tsa setaele ka lebaka la thepa ea eona ea ho tenya le ho etsa filimi.
Mekhoa ea Tlhokomelo ea Letlalo: E sebelisoa ka litlolong, litlolong tsa letsatsi le li-sunscreen e le stabilizer le emulsifier.
Mekhoa ea ho kopanya HPMC:
HPMC e etsoa ka letoto la liphetoho tsa lik'hemik'hale tsa cellulose. Ts'ebetso ena e kenyelletsa ho etherification ea cellulose ka propylene oxide le methyl chloride ho hlahisa lihlopha tsa hydroxypropyl le methyl, ka ho latellana. Tekanyo ea phetolo (DS) ea lihlopha tsa hydroxypropyl le methyl e ka laoloa ho etsa hore thepa ea HPMC e lumellane le lits'ebetso tse itseng.
(5)Tsoelo-pele ea morao tjena le Mekhoa ea Lipatlisiso:
Li-Nanocomposite: Bafuputsi ba ntse ba hlahloba ho kenyelletsoa ha li-nanoparticles ka har'a matrices ea HPMC ho ntlafatsa thepa ea mechini, bokhoni ba ho jara lithethefatsi, le boitšoaro bo laoloang ba ho lokolla.
Khatiso ea 3D: Li-hydrogel tse thehiloeng ho HPMC li ntse li fuputsoa bakeng sa tšebeliso ea bioprinting ea 3D ea li-scaffolds tsa lisele le litsamaiso tsa ho fana ka meriana ka lebaka la ho lumellana ha tsona le thepa ea tsona e ka fetoloang.
Lisebelisoa tse Bohlale: Lisebelisoa tse thehiloeng ho HPMC li ntse li etsoa hore li arabele lintho tse ka ntle tse kang pH, mocheso le khanya, e leng se nolofalletsang nts'etsopele ea litsamaiso tse bohlale tsa ho fana ka lithethefatsi le li-sensor.
Li-Bioink: Li-bioink tse thehiloeng ho HPMC li ntse li fumana tlhokomelo bakeng sa bokhoni ba tsona lits'ebetsong tsa bioprinting, e leng se nolofalletsang tlhahiso ea likarolo tse rarahaneng tsa lisele tse nang le matla a phahameng a ho phela le taolo ea sebaka.
Lisebelisoa tse thehiloeng ho HPMC li fana ka melemo e mengata indastering e fapaneng, ho kenyeletsoa meriana, lijo, kaho le litlolo. Ka motsoako oa tsona o ikhethang oa thepa, ho kenyeletsoa ho qhibiliha ha metsi, taolo ea viscosity, le ho bola ha lintho tse phelang, lisebelisoa tse thehiloeng ho HPMC li ntse li tsoela pele ho khanna boqapi saenseng ea lintho tse bonahalang, ho nolofalletsa nts'etsopele ea litsamaiso tse tsoetseng pele tsa ho fana ka meriana, lijo tse sebetsang, lisebelisoa tsa kaho tse tsitsitseng, le lisele tse hatisitsoeng ka bioprinted. Ha lipatlisiso lefapheng lena li ntse li tsoela pele, re ka lebella tsoelo-pele e eketsehileng le lits'ebetso tse ncha tsa lisebelisoa tse thehiloeng ho HPMC haufinyane.
