Amandla okugcina amanzi e-hydroxypropyl methylcellulose ancike kokuqukethwe kwe-hydroxypropyl.Ngaphansi kwezimo ezifanayo, amandla okugcina amanzi e-hydroxypropyl methylcellulose ephezulu anamandla, futhi okuqukethwe kwe-methoxy kokuqukethwe okufanayo kwe-hydroxypropyl kuyehliswa ngokufanelekile..Ukuphakama kokuqukethwe kwe-hydroxypropyl methylcellulose, kuyanda ukubukeka kwayo, ngakho-ke lapho ukhetha umkhiqizo, kufanele ukhethe umkhiqizo ofanelana nawe ngokwenhloso yomkhiqizo.
Izinga lokushisa nezinye izici zinomthelela ekugcineni amanzi e-hydroxypropyl methylcellulose.
Izinga lokushisa lejeli elishisayo:
I-Cellulose ether HPMC inezinga lokushisa eliphezulu le-thermal gelation kanye nokugcinwa kwamanzi okuhle;kunalokho, inokugcinwa kwamanzi okungekuhle.
I-viscosity ye-cellulose ether HPMC:
Lapho i-viscosity ye-HPMC ikhula, ukugcinwa kwayo kwamanzi kuyanda;lapho i-viscosity ikhula ngezinga elithile, ukwanda kokugcinwa kwamanzi kunciphisa.
I-Cellulose ether HPMC i-homogeneous:
I-HPMC inokusabela okufanayo, ukusatshalaliswa okufanayo kwe-methoxyl ne-hydroxypropoxyl, futhi inokugcinwa kwamanzi okuhle.
Umthamo we-Cellulose ether HPMC:
Lapho umthamo ukhula, izinga lokugcinwa kwamanzi liyakhuphuka futhi umphumela wokugcina amanzi usobala.
Uma inani elingeziwe lingu-0.25~0.6%, izinga lokugcinwa kwamanzi likhuphuka ngokushesha ngokunyuka kwenani elingeziwe;lapho inani elingeziwe likhuphuka ngokuqhubekayo, ukuthambekela kokukhuphuka kwezinga lokugcinwa kwamanzi kuyehla.
Ngamafuphi, ukugcinwa kwamanzi kwe-HPMC kuhlobene nezici ezifana nezinga lokushisa kanye ne-viscosity, futhi ukugcinwa kwamanzi kwawo kuhlobene nenani le-hydroxypropyl methylcellulose engeziwe.Uma inani le-hydroxypropyl methylcellulose lifinyelela inani elithile, ukusebenza kwalo kokugcinwa kwamanzi kufinyelela ibhalansi.
