Porogaramu nyamukuru ya hydroxypropyl methylcellulose

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

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?

HPMC irashobora kugabanwa muburyo bwubwoko nubwoko bushyushye.Ubwoko bwibicuruzwa ako kanya 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. Ni ubuhe buryo bwo gusesa hydroxypropyl methylcellulose (HPMC)?

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

1) Shira amazi asabwa muri kontineri hanyuma uyashyuhe kuri 70 ° C.Hydroxypropyl methylcellulose yongeweho buhoro buhoro buhoro buhoro, mu ikubitiro HPMC ireremba hejuru y’amazi, hanyuma buhoro buhoro ikora ibibyimba, bikonjeshwa bikurura.

2), 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.]

4. Nigute dushobora gusuzuma ubwiza bwa hydroxypropyl methylcellulose (HPMC) byoroshye kandi byihuse?

.Nyamara, ibyinshi mubicuruzwa byiza bifite umweru mwiza.

(2) Ubwiza: Ubwiza bwa HPMC mubusanzwe bufite mesh 80 na mesh 100, naho mesh 120 ni mike.HPMC nyinshi ikorerwa muri Hebei ni mesh 80.Nibyiza, mubisanzwe, nibyiza.

.Ninini yohereza urumuri, nibyiza, byerekana ko harimo ibidashobora gukemuka muri byo..Ubucucike bwa reaction ya vertical muri rusange nibyiza, kandi nibya reaction ya horizontal ni bibi, ariko ntibisobanuye ko ubwiza bwa reaction ya vertical iruta iya reaction ya horizontal, kandi ubwiza bwibicuruzwa bugenwa nibintu byinshi.

(4) Uburemere bwihariye: Ninini nini ya rukuruzi, niko iremereye.Umwihariko ni munini, muri rusange kubera ko ibiri mu itsinda rya hydroxypropyl muri yo ari byinshi, kandi ibikubiye mu itsinda rya hydroxypropyl ni byinshi, gufata amazi ni byiza.
