Imikoreshereze ya hydroxypropyl methylcellulose HPMC

1. Intego nyamukuru ya hydroxypropyl methyl selulose (HPMC) niyihe?

HPMC ikoreshwa cyane mubikoresho byubwubatsi, gutwikira, ibisigazwa byubukorikori, ububumbyi, ubuvuzi, ibiryo, imyenda, ubuhinzi, kwisiga, itabi nizindi nganda. HPMC irashobora kugabanywa mubyiciro byubwubatsi, ibyiciro byibiribwa nicyiciro cyubuvuzi ukurikije intego yabyo. Kugeza ubu, ibicuruzwa byinshi byo murugo biri murwego rwo kubaka. 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 methyl selulose (HPMC). Ni irihe tandukaniro riri hagati yimikoreshereze yabo?

HPMC irashobora kugabanwa muburyo bwubwoko nubwoko bushushe. Ibicuruzwa byubwoko bwihuse bikwirakwizwa vuba mumazi akonje bikabura mumazi. Muri iki gihe, amazi ntagira ubwiza, kubera ko HPMC ikwirakwizwa mu mazi gusa nta gushonga. Hafi yiminota 2, ubwiza bwamazi bwiyongereye buhoro buhoro, bikora colloid ibonerana. Ibicuruzwa bishyushye, iyo bihuye namazi akonje, birashobora gukwirakwira vuba mumazi ashyushye bikabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ubukonje bugaragara buhoro buhoro kugeza igihe habaye ibibyimba bisobanutse neza. Ubwoko bushyushye burashobora gukoreshwa gusa muri poro ya pome na minisiteri. Muri kole y'amazi no gusiga irangi, gufunga bibaho kandi ntibishobora gukoreshwa. Ubwoko bwakanya bufite intera yagutse ya porogaramu. Irashobora gukoreshwa mubifu ya poro na minisiteri, kimwe no mumazi ya kole hamwe n irangi. Nta kwivuguruza.

3. Ni ubuhe buryo bwo gusesa hydroxypropyl methylcellulose HPMC?

Uburyo bwo gushonga amazi ashyushye: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gukwirakwizwa kimwe mumazi ashyushye mugihe cyambere, hanyuma igashonga vuba mugihe cyo gukonja. Uburyo bubiri busanzwe busobanurwa gutya:

1). Ongeramo 1/3 cyangwa 2/3 by'amazi asabwa muri kontineri hanyuma ubishyuhe kuri 70 ° C. gukwirakwiza HPMC kugirango utegure amazi ashyushye; hanyuma ongeramo amazi asigaye mumazi ashyushye Muri slurry, shyira imvange nyuma yo gukurura.

Uburyo bwo kuvanga ifu. ya HPMC Ifu izahita ishonga iyo ihuye namazi. -Ifu yuzuye ifu nabakora minisiteri bakoresha ubu buryo. [Hydroxypropyl methyl selulose (HPMC) ikoreshwa nkumubyimba mwinshi kandi ugumana amazi mumashanyarazi ya poro.

Shira amazi asabwa muri kontineri hanyuma ubishyuhe kugeza kuri 70 ° C. Buhoro buhoro ongeramo hydroxypropyl methylcellulose hamwe no gukurura buhoro, tangira HPMC ireremba hejuru y’amazi, hanyuma buhoro buhoro ukora ibishishwa, hanyuma ukonje ibishishwa ukoresheje.
