Gukoresha hydroxypropyl methylcellulose

1. Ni ubuhe buryo bukoreshwa bwa hydroxypropyl methylcellulose (HPMC)?

Igisubizo: HPMC ikoreshwa cyane mubikoresho byubwubatsi, gutwikira, ibisigazwa byubukorikori, ububumbyi, ubuvuzi, ibiryo, imyenda, ubuhinzi, kwisiga, itabi nizindi nganda.HPMC irashobora kugabanywa mubyiciro byubwubatsi, icyiciro cyibiribwa nicyiciro cya farumasi ukurikije intego.Kugeza ubu, ibyinshi mubicuruzwa byo murugo ni urwego rwubwubatsi.Mu cyiciro cyubwubatsi, ifu ya putty ikoreshwa mubwinshi, hafi 90% ikoreshwa kubifu ya putty, naho ibindi bikoreshwa mumasima ya sima na kole.

2. Hariho ubwoko bwinshi bwa hydroxypropyl methylcellulose (HPMC), kandi ni irihe tandukaniro mugukoresha?

Igisubizo: HPMC irashobora kugabanywa muburyo bwubwoko nubwoko bushyushye.Ibicuruzwa byubwoko bwihuse bikwirakwira vuba mumazi akonje bikabura mumazi.Muri iki gihe, amazi ntagira ubwiza kuko HPMC ikwirakwizwa mumazi gusa nta gushonga nyabyo.Hafi yiminota 2, ubwiza bwamazi bugenda bwiyongera buhoro buhoro, bukora colloid ibonerana.Ibicuruzwa bishyushye, iyo bihuye namazi akonje, birashobora gukwirakwira vuba mumazi ashyushye bikabura mumazi ashyushye.Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ibishishwa bizagaragara buhoro buhoro kugeza igihe bibumbiye mu mucyo.Ubwoko bushyushye burashobora gukoreshwa gusa mubifu ya pome na minisiteri.Muri kole yamazi no gusiga irangi, hazabaho guterana ibintu kandi ntibishobora gukoreshwa.Ubwoko bwakanya bufite intera yagutse ya porogaramu.Irashobora gukoreshwa mu ifu yuzuye ifu na minisiteri, hamwe na kole yamazi hamwe n irangi, nta kubuza.

3. Nubuhe buryo bwo gusesa hydroxypropyl methylcellulose HPMC?

Igisubizo: Uburyo bwo gushonga amazi ashyushye: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gukwirakwizwa neza mumazi ashyushye mugihe cyambere, hanyuma igashonga vuba iyo ikonje.Uburyo bubiri busanzwe busobanurwa gutya:

1), ongeramo 1/3 cyangwa 2/3 by'amazi asabwa muri kontineri, hanyuma ubishyuhe kugeza kuri 70 ° C, ukwirakwiza HPMC ukurikije uburyo bwa 1), hanyuma utegure amazi ashyushye;hanyuma shyiramo amazi asigaye asigaye mumazi ashyushye, imvange yarakonje nyuma yo gukurura.

Uburyo bwo kuvanga ifu: vanga ifu ya HPMC ninshi mubindi bintu byifu yifu, vanga neza na mixer, hanyuma ushyiremo amazi kugirango ushonga, hanyuma HPMC irashobora gushonga muriki gihe nta agglomeration, kuko muri HPMC nkeya gusa Inguni Ifu, izahita ishonga mugihe uhuye namazi.—— Ifu yuzuye ifu nabakora minisiteri bakoresha ubu buryo.[Hydroxypropyl methylcellulose (HPMC) ikoreshwa nk'umubyimba mwinshi kandi ugumana amazi muri pompe ya poro.

2) Shira amazi asabwa mubikoresho hanyuma ubishyuhe kugeza kuri 70 ° C.Hydroxypropyl methylcellulose yongeweho buhoro buhoro buhoro buhoro, mu ikubitiro HPMC ireremba hejuru y’amazi, hanyuma buhoro buhoro ikora ibibyimba, bikonjeshwa bikurura.
