Diluting Hydroxypropyl Methylcellulose (HPMC) hangata e kenyelletsa ho e kopanya le sehlapi se loketseng kapa se qhalakanya ho fihlela mahloriso a lakatsehang.HPMC ke polymer e sebelisoang haholo ho tsa meriana, litlolo, le lihlahisoa tsa lijo ka lebaka la thepa ea eona e teteaneng, e tsitsitseng le ea ho etsa lifilimi.Hangata dilution ea hlokahala ho lokisa viscosity ea eona kapa mahloriso bakeng sa lits'ebetso tse ikhethileng.
Ho utloisisa HPMC:
Sebopeho sa Lik'hemik'hale: HPMC ke polymer ea semi-synthetic e nkiloeng ho selulose.E na le likarolo tse pheta-phetoang tsa limolek'hule tsa tsoekere tse nang le hydroxypropyl le lihlopha tsa methyl tse khomaretsoeng.
Thepa: HPMC e qhibiliha ka metsing le metsoako e meng ea tlhaho e kang joala le acetone.Ho qhibiliha ha eona ho itšetlehile ka lintho tse kang boima ba limolek'hule, tekanyo ea ho fetola, le mocheso.
Lintlha Tseo U Lokelang ho li Nahana Pele ho Dilution:
Tlhokahalo ea Boikutlo: Etsa qeto ea hore na HPMC e batlile hakae bakeng sa kopo ea hau.Sena se ka fapana ho latela lintlha tse kang viscosity, thepa ea ho etsa lifilimi, le ho lumellana le lisebelisoa tse ling.
Khetho ea Solvent: Khetha sehlapi kapa se qhalakanya se loketseng kopo ea hau mme se lumellana le HPMC.Li-solvents tse tloaelehileng li kenyelletsa metsi, lino tse tahang (mohlala, ethanol), glycols (mohlala, propylene glycol), le metsoako ea tlhaho (mohlala, acetone).
Thempereichara: Likereiti tse ling tsa HPMC li ka hloka maemo a itseng a mocheso bakeng sa ho qhibiliha.Etsa bonnete ba hore mocheso oa solvent o loketse ho kopanya hantle le ho qhibiliha.
Mehato ea ho fokotsa HPMC:
Lokisa Thepa:
Lijana tse kopanyang tse hloekileng le tse omeletseng, lithupa tse hlohlelletsang le lisebelisoa tse lekanyang ho thibela tšoaetso.
Etsa bonnete ba hore ho na le moea o nepahetseng haeba o sebelisa lihlapolli tsa tlhaho ho qoba likotsi tsa ho hema.
Bala Karolelano ea Dilution:
Fumana palo e hlokahalang ea HPMC le solvent ho ipapisitse le khatello ea ho qetela e lakatsehang.
Lekanya ka nepo palo e hlokahalang ea phofo ea HPMC u sebelisa tekanyo kapa tekanyo ea ho lekanya.
Lekanya molumo o loketseng oa solvent ho latela tekanyo e baliloeng ea dilution.
Mokhoa oa ho Kopanya:
Qala ka ho eketsa solvent ho setshelo sa ho kopanya.
Butle-butle u fafatse phofo ea HPMC ka har'a solvent ha u ntse u susumetsa ka mokhoa o sa khaotseng ho thibela ho phunyeha.
Tsoela pele ho susumetsa ho fihlela phofo ea HPMC e hasane ka ho feletseng ka har'a solvent.
Ka boikhethelo, o ka sebelisa ho ferekanngoa ha mechine kapa sonication ho ntlafatsa ho hasana.
Lumella ho Felisoa:
Etsa hore motsoako o eme nako e itseng ho etsa bonnete ba ho qhibiliha ka ho feletseng ha likaroloana tsa HPMC.Nako ea ho qhibiliha e ka fapana ho ea ka lintlha tse kang mocheso le pherekano.
Tlhahlobo ea Boleng:
Lekola viscosity, ho hlaka, le homogeneity ea tharollo ea HPMC e hlapolotsoeng.Fetola karo-karolelano ea mahloriso kapa solvent ha ho hlokahala.
Polokelo le Ts'ebetso:
Boloka tharollo ea HPMC e hlapolotsoeng ka har'a sets'oants'o se hloekileng, se tiisitsoeng ka thata ho thibela tšilafalo le mouoane.
Latela likhothaletso tsa polokelo tse fanoeng ke moetsi, haholo mabapi le mocheso le ho pepesehela khanya.
Malebela le Litlhokomelo tsa Tšireletso:
Safety Gear: Apara lisebelisoa tse nepahetseng tsa ho itšireletsa (PPE) joalo ka liatlana le likhalase tsa tšireletso, haholo ha u sebetsana le lihlapolli tsa tlhaho.
Qoba Tšilafalo: Boloka lisebelisoa tsohle le lijana li hloekile ho thibela tšilafalo, e ka amang boleng ba tharollo e hlapolotsoeng.
Taolo ea Mocheso: Boloka maemo a mocheso a tsitsitseng nakong ea ts'ebetso ea dilution ho netefatsa liphetho tse ka hlahisoang hape.
Teko ea Tšebelisano: Etsa liteko tsa tšebelisano le lisebelisoa tse ling kapa li-additives tse tla kopanngoa le tharollo ea HPMC e hlapollotsoeng ho qoba mathata a tlhahiso.
Diluting HPMC e kenyelletsa ho nahanisisa ka hloko ha lintlha tse kang litlhoko tsa mahloriso, khetho ea solvent, le mekhoa ea ho kopanya.Ka ho latela lits'ebetso tse nepahetseng le mehato ea ts'ireletso, u ka khona ho lokisa litharollo tsa HPMC tse hlapolotsoeng tse ipapisitseng le litlhoko tsa hau tsa kopo.Kamehla sheba litataiso tsa moetsi 'me u etse liteko tse hlokahalang tsa tšebelisano ho netefatsa ts'ebetso e nepahetseng le boleng ba sehlahisoa.
