Hydroxypropyl methylcellulose (HPMC) ke polymer e sebetsang ka bongata e sebelisoang haholo liindastering tse fapaneng ho kenyelletsa le meriana, lijo, kaho le litlolo.E 'ngoe ea likarolo tsa eona tsa bohlokoa ke viscosity, e phethang karolo ea bohlokoa ho khethollang ts'ebetso ea eona lits'ebetsong tse fapaneng.Ho utloisisa boits'oaro ba viscosity ea HPMC ho bohlokoa bakeng sa ho ntlafatsa tlhahiso ea lihlahisoa, ho netefatsa boleng ba sehlahisoa, le ho ntlafatsa ts'ebetso ea ts'ebetso.
1. Indasteri ea meriana:
Meetsong ea meriana, HPMC e na le mefuta e fapaneng ea ts'ebeliso, ho kenyeletsoa joalo ka se tlamella, se etsang lifilimi, le moemeli oa tokollo e laoloang.The viscosity ea tharollo ea HPMC e ama haholo kinetics ea ho lokolloa ha lithethefatsi, ho arohana ha letlapa, le ts'ebetso ea sehlahisoa sa lithethefatsi ka kakaretso.Ho utloisisa boitšoaro ba viscosity ea HPMC ho thusa baetsi ba lihlahisoa ho hlophisa mekhoa ea ho fana ka lithethefatsi ho latela litlaleho tse khethehileng tsa tokollo, litlhoko tsa bioavailability, le litlhoko tsa mokuli.Ntle le moo, taolo e nepahetseng ea viscosity e thusa ho fihlela letlapa le ts'oanang, ho netefatsa ho ts'oana ha litekanyetso le ho fokotsa phapang ea batch-to-batch.
2. Indasteri ea lijo:
Indastering ea lijo, HPMC e sebelisoa joalo ka mokhoa oa ho tsitsisa, motenya, le emulsifier lihlahisoa tse fapaneng, joalo ka lisoso, thepa e halikiloeng le lihlahisoa tsa lebese.Viscosity ea tharollo ea HPMC e ama sebopeho, molomo le botsitso ba lihlahisoa tsa lijo.Ka ho utloisisa boits'oaro ba viscosity ea HPMC, litsebi tsa mahlale a lijo li ka ntlafatsa litlolo ho fihlela thepa ea rheological e lakatsehang joalo ka viscosity, boits'oaro ba ho kuta, le botsitso ba ho emisa.Sena se netefatsa boleng bo tsitsitseng ba sehlahisoa, litšoaneleho tse matlafalitsoeng tsa kutlo le nako e telele ea nako, ho fihlela litebello tsa bareki le litekanyetso tsa taolo.
3.Indasteri ea kaho:
Lits'ebetsong tsa kaho, HPMC e atisa ho sebelisoa ka thepa ea samente e kang seretse, li-grouts le metsoako ea ho ikemela ho ntlafatsa ts'ebetso, ho boloka metsi le ho khomarela.Viscosity ea seretse sa HPMC e ama ka kotloloho litšobotsi tsa eona tsa ho pompa, ho hasana le ho hlakola libakeng tsa kaho.Ho utloisisa boits'oaro ba viscosity ea HPMC ho thusa baenjiniere le bo-rakonteraka ho hlophisa litlhophiso ho fihlela litlhoko tse ikhethileng tsa ts'ebetso joalo ka nako e bulehileng, ho hanyetsa ho sag le matla a bond.Sena se nolofatsa ts'ebeliso e sebetsang, se fokotsa litšila tsa thepa, 'me se matlafatsa nako e telele le botle ba sebopeho se felileng.
4. Indasteri ea litlolo:
Indasteri ea litlolo, HPMC e sebelisoa e le motenya, pele filimi, le stabilizer lihlahisoa tse sa tšoaneng, ho akarelletsa le litlolo, lotions, le metsoako ea tlhokomelo ea moriri.The viscosity ea tharollo ea HPMC e ama ho ata, botsitso ba emulsion, le thepa ea kutlo ea litlolo tsa litlolo.Ka ho utloisisa boitšoaro ba viscosity ea HPMC, baetsi ba litlolo ba ka rala lihlahisoa tse nang le sebopeho se lakatsehang, chebahalo le litšobotsi tsa ts'ebetso.Sena se nolofalletsa nts'etsopele ea liforomo tse ntle le tse ntle tse fanang ka ts'ebeliso e bonolo, liphetho tse tšoarellang nako e telele le khotsofalo e eketsehileng ea bareki.
5. Ntlafatso ea ts'ebetso:
Ho utloisisa boitšoaro ba viscosity ea HPMC ho bohlokoa hape bakeng sa ntlafatso ea ts'ebetso ts'ebetsong ea tlhahiso.Ebang ke ka har'a khatello ea letlapa, ho lokisa lijo, ho kopanya thepa ea kaho kapa ho etsa litlolo, taolo e nepahetseng ea viscosity e thusa boleng ba sehlahisoa bo sa fetoheng, ho ikatisa le ho kotuloa.Ka ho tsebahatsa thepa ea rheological ea tharollo ea HPMC, baenjiniere ba ts'ebetso ba ka lokisa maemo a tlhahiso e ntle joalo ka lebelo la ho kopanya, sekhahla sa ho kuta le mocheso ho fihlela maemo a nepahetseng a ts'ebetso.Sena se fokotsa nako ea tlhahiso, se fokotsa tšebeliso ea matla, 'me se ntlafatsa katleho ea tlhahiso ka kakaretso.
Ho utloisisa boitšoaro ba viscosity ea hydroxypropyl methylcellulose (HPMC) ho bohlokoa bakeng sa liindasteri tse fapaneng tse kenyelletsang meriana, lijo, kaho le litlolo.Viscosity ea tharollo ea HPMC e ama haholo ts'ebetso ea sehlahisoa, botsitso ba sebopeho le ts'ebetso ea ts'ebetso.Ka ho utloisisa boits'oaro ba viscosity ea HPMC, bankakarolo ba ka khona ho hlophisa litlhophiso, ba ntlafatsa lits'ebetso, le ho fana ka lihlahisoa tsa boleng bo holimo tse fihlelang litlhoko tsa bareki le litekanyetso tsa taolo.Ka hona, ho tsetela ho sebopeho le kutloisiso ea boits'oaro ba viscosity ea HPMC ho bohlokoa ho nts'etsapele boqapi, ho eketsa tlholisano, le ho netefatsa katleho tikolohong ea 'maraka e matla ea kajeno.
