Umhlahlandlela Wokukhetha Amabanga e-HPMC kanye ne-Viscosity Wezimbozo Zokwakha kanye Nezicelo Zezimboni

Isingeniso

I-Hydroxypropyl Methylcellulose HPMCingenye yama-ether e-cellulose abaluleke kakhulu asetshenziswa kuzo zonke izinto zokwakha, imithi kanye nemikhiqizo yokunakekelwa komuntu siqu. Ukukhetha ibanga elifanele le-HPMC kubalulekile ngoba izinga lokushintshana kwe-viscosity kanye nokuziphatha kokuncibilika kuthinta ngqo ukusebenza komkhiqizo.

Lapha kunikeza incazelo ephelele nesebenzayo yamamaki e-HPMC kufaka phakathi ukufanisa uhlelo lokusebenza lokuhlukaniswa kwe-viscosity kanye namasu okukhetha ochwepheshe ukusiza abakhiqizi onjiniyela nabathengi bakhethe ikhambi elifanele kakhulu.

Kuyini i-HPMC

I-HPMC iyi-ether ye-cellulose engeyona i-ionic etholakala ku-cellulose yemvelo ngokuguqulwa kwamakhemikhali. Ihlinzeka ngokusebenza okunemisebenzi eminingi njengokwakheka kwefilimu yokuqina nokuqina kokugcinwa kwamanzi.

Izakhiwo ezibalulekile zifaka phakathi
