Emva kokongeza i-hydroxypropyl methylcellulose kwizinto ezisekwe kwisamente, inokujiya. Isixa se-hydroxypropyl methylcellulose sinquma isidingo samanzi sezinto ezisekelwe kwi-samente, ngoko kuya kuchaphazela ukukhutshwa komdaka.
Izinto ezininzi ezichaphazela i-viscosity ye-hydroxypropyl methylcellulose:
1. Iqondo eliphezulu le-polymerization ye-cellulose ether, ubukhulu bayo ubunzima be-molecular, kunye nokuphakama kwe-viscosity yesisombululo samanzi;
2. I-high intake (okanye i-concentration) ye-cellulose ether, iphezulu i-viscosity yesisombululo sayo samanzi. Nangona kunjalo, kuyimfuneko ukubeka ingqalelo ekukhetheni ukufakwa okufanelekileyo ngexesha lokufaka isicelo ukuze kugwenywe ukungena ngokugqithiseleyo, okuya kuchaphazela umsebenzi wodaka kunye nekhonkrithi. uphawu;
3. Njengamanzi amaninzi, i-viscosity yesisombululo se-ether ye-cellulose iya kuncipha ngokunyuka kweqondo lokushisa, kwaye iphezulu i-concentration ye-cellulose ether, impembelelo enkulu yeqondo lokushisa;
4. Isisombululo se-Hydroxypropyl methylcellulose ngokuqhelekileyo i-pseudoplastic, enepropati ye-shear thinning. Ixabiso elikhulu lokucheba ngexesha lovavanyo, i-viscosity ephantsi.
Ngoko ke, ukudityaniswa kodaka kuya kuncipha ngenxa yamandla angaphandle, okunenzuzo ekukhutsheni ukwakhiwa kodaka, okubangelwa ukusebenza kakuhle kunye nokubambisana kodaka ngexesha elifanayo.
Isisombululo se-hydroxypropyl methylcellulose siya kubonisa iimpawu ze-Newtonian fluid xa i-concentration iphantsi kakhulu kwaye i-viscosity iphantsi. Xa ugxininiso lukhula, isisombululo siya kubonisa ngokuthe ngcembe iimpawu ze-pseudoplastic fluid, kwaye ukuphakama koxinzelelo, kucacile ngakumbi i-pseudoplasticity.
