Umthamo wokugcina amanzi we-hydroxypropylllylylylylylylylylylylylyly turylcellose kuncike kokuqukethwe kwe-hydroxypropyl. Ngaphansi kwezimo ezifanayo, umthamo wokugcina amanzi we-hydroxyproppropylykyrkyr methylcellulose unamandla, futhi okuqukethwe kwe-methoxy kokuqukethwe okufanayo kwe-hydroxypropylyl kuncishiswe ngokufanele. . Lapho kukhuphuka okuqukethwe kwe-hydroxypropylllylylyly, kukhudlwana ukubonakala kwawo, ngakho-ke lapho ukhetha umkhiqizo, kufanele ukhethe umkhiqizo ofanele ngokwenhloso yomkhiqizo.
Izinga lokushisa nezinye izinto zinomphumela wokugcinwa kwamanzi we-hydroxypropylllylyll methylcellulose.
Ukushisa kwe-Thermal Gel:
I-CelluleOse Ether HPMC inokushisa okuphezulu okushisayo nokugcinwa kwamanzi okuhle; Ngokuphambene nalokho, inokugcinwa kwamanzi okumpofu.
I-Viscosity of Cellulose Ether HPMC:
Lapho ukubonwa kwe-HPMC kukhuphuka, ukugcinwa kwawo kwamanzi kuyanda; Lapho i-viscosity inyuka ngezinga elithile, ukwanda kokugcinwa kwamanzi kuyancipha.
I-Cellule
I-HPMC inokusabela okufanayo, ukusatshalaliswa okufanayo kwe-methoxyl ne-hydroxypropoposyl, futhi kunokugcinwa kwamanzi okuhle.
Umthamo we-Cellulose ether HPMC:
The dosage more the dosage, isilinganiso sokugcinwa kwamanzi kanye nokusobala okusobala kokugcina amanzi.
Lapho inani lokungezwa lingu-0.25 ~ 0.6%, inani lokugcina amanzi likhuphuka ngokushesha ngokwanda kwenani lokungezwa; Lapho inani lokungezwa likhuphuka ngokuqhubekayo, ukukhuphuka kwenani lokugcinwa kwamanzi lincibilika.
Ngamafuphi, ukugcinwa kwamanzi kwe-HPMC kuhlobene nezici ezifana nokushisa nokubonakala, kanye nokugcinwa kwayo kwamanzi kuhlobene nenani le-hydroxypropyllllllylvellose. Lapho inani le-hydroxypropyllllllllyllose lifinyelela inani elithile, ukusebenza kwalo kokugcina amanzi kufinyelela esele.
