I-Hydroxylopenyl cellulose (HPMC) yipolymer yokwenziwa esetyenziswa ngokubanzi kwizicelo ezahlukeneyo ezifana neziyobisi, ukutya, izakhiwo kunye nezinto zokuthambisa.Iphuma kwi-cellulose kwaye yenza i-glue coagulant kwi-hydrophilic.Ifomu ecocekileyo ye-HPMC ngumgubo omhlophe ongenancasa ochithwa emanzini ukuze wenze isisombululo se-mucus esicacileyo.
Ukukrexeza kwe-HPMC yinkqubo yokongeza okanye exutywe izinto ezisulungekileyo kwezinye izinto zokutshintsha iimpawu zayo okanye ukunciphisa iindleko zemveliso.I-doping kwi-HPMC inokutshintsha iipropati zomzimba, iikhemikhali kunye nezomatshini ze-HPMC.I-HPMC isebenzisa ii-agents ezininzi ze-doping, eziquka isitashi, iprotein yomdiliya, i-cellulose, i-sucrose, i-glucose, i-carboxymethyl cellulose sodium (CMC) kunye ne-polyethylene ethylene (PEG).Ukongezwa kwaba bantu badala kuya kuwonakalisa umgangatho, ukhuseleko kunye nokusebenza kakuhle kwe-HPMC.
Kukho umahluko oliqela phakathi kwe-HPMC esulungekileyo kunye neselulosi yokukrexeza:
1. Ubunyulu: Umahluko ophambili phakathi kwe-HPMC esulungekileyo kunye neselulosi yokukrexeza kukucoceka kwabo.I-HPMC ecocekileyo yinto enye ngaphandle kokungcola okanye izongezo.Kwelinye icala, ukukrexeza cellulose iqulathe ezinye izinto, ezinokuba ezinye izinto ngabom okanye ngempazamo kuchaphazela umgangatho wabo kunye neempawu.
2. Iimpawu zomzimba: I-HPMC ecocekileyo luhlobo lomgubo omhlophe, ongenancasa, onyibilikayo emanzini ukwenza isisombululo se-viscous esicacileyo.I-HPMC yokukrexeza inokuba neempawu zomzimba ezahlukeneyo, ngokuxhomekeke kuhlobo kunye nobuninzi be-arhente yokukrexeza eyongezelelweyo.Ukwamkelwa kunokuchaphazela ukunyibilika, i-viscosity kunye nombala wezinto eziphathekayo.
3. Iimpawu zeMichiza: I-HPMC ecocekileyo yipolima ecocekileyo kakhulu eneempawu zeekhemikhali ezihambelanayo.Ukwamkelwa kwezinye izinto kunokutshintsha iimpawu zemichiza ye-HPMC, echaphazela imisebenzi yayo kunye nokhuseleko.
4. Ukhuseleko: Ukusetyenziswa kwe-cellulose yokukrexeza kunokuba yingozi empilweni kuba oku kukrexeza kusenokuba nezinto eziyityhefu okanye eziyingozi.I-HPMC yokukrexeza inokunxibelelana nezinye izinto ngendlela engalindelekanga, nto leyo ebangela iingxaki zempilo ezimandundu.
5. Iindleko: I-cellulose esetyenzisiweyo inexabiso eliphantsi kune-HPMC ecocekileyo, kuba ukongezwa kwee-doping agents kuya kunciphisa iindleko zokuvelisa.Nangona kunjalo, ukusetyenziswa kokukrexeza kwe-HPMC ekwenzeni amachiza okanye ezinye iimveliso kungonakalisa umgangatho kunye nokusebenza kakuhle kwemveliso.
Lilonke, i-HPMC esulungekileyo yipolymer esulungekileyo kwaye ekhuselekileyo, eneekhemikhali ezingaguqukiyo kunye neempawu zomzimba.Ukukrexeza kunye nezinye izinto kunokutshintsha iimpawu ze-HPMC, ngokonakalisa umgangatho kunye nokhuseleko lwemveliso.Ke ngoko, i-HPMC esulungekileyo kufuneka isetyenziswe ekwenzeni amachiza, ukutya, izakhiwo kunye nezinye iimveliso.
