Ni irihe tandukaniro HPMC ifite cyangwa idafite S?

1. HPMC igabanijwe muburyo bwubwoko nubwoko bwihuse

Ubwoko bwa HPMC bwihuta bwongeweho inyuguti ya S, kandi glyoxal igomba kongerwaho mugihe cyo gukora.

Ubwoko bwa HPMC bwihuse ntabwo bwongeyeho inyuguti iyo ari yo yose, nka "100000 ″ bisobanura" 100000 viscosity yihuta ikwirakwiza HPMC ".

2. Hamwe na S cyangwa idafite S, ibiranga biratandukanye

HPMC yatatanye vuba ikwirakwira vuba iyo ihuye namazi akonje ikabura mumazi. Muri iki gihe, amazi ntagira ubwiza, kubera ko HPMC ikwirakwizwa mu mazi gusa nta gushonga. Nyuma yiminota igera kuri ibiri, ubwiza bwamazi bugenda bwiyongera buhoro buhoro, bikora ibibyibushye bibonerana Thick colloid.

HPMC ako kanya irashobora gukwirakwizwa vuba mumazi ashyushye kuri 70 ° C. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ibishishwa bizagaragara buhoro buhoro kugeza igihe ibinyabuzima bibonerana biboneye.

3. Hamwe na S cyangwa idafite, intego iratandukanye

HPMC ako kanya irashobora gukoreshwa gusa muri poro ya poro na minisiteri. Muri kole yamazi, gusiga amarangi no gukaraba, hazabaho ibintu byo guteranya kandi ntibishobora gukoreshwa.

HPMC yatatanye vuba ifite porogaramu nyinshi kandi irashobora gukoreshwa mu ifu yuzuye, minisiteri, kole yamazi, irangi, hamwe no gukaraba ibicuruzwa nta kubuza kubuza.

Uburyo bwo gusesagura

1. Fata amazi asabwa asabwa, uyashyire muri kontineri hanyuma uyashyire hejuru ya 80 ° C, hanyuma wongereho ibicuruzwa buhoro buhoro. Cellulose ireremba hejuru y’amazi ubanza, ariko igenda ikwirakwira buhoro buhoro kugirango ibe imwe. Igisubizo cyakonje mugihe gikurura.

2. Ubundi, shyushya 1/3 cyangwa 2/3 byamazi ashyushye hejuru ya 85 ° C, ongeramo selile kugirango ubone amazi ashyushye, hanyuma ushyiremo amazi asigaye asigaye, komeza ubyuke, hanyuma ukonje imvange yavuyemo.

3. Urushundura rwa selile rumeze neza, kandi rubaho nkutuntu duto duto duto twa porojeri iringaniye, kandi irashonga vuba iyo ihuye namazi kugirango ikore neza.

4. Buhoro buhoro kandi bingana kongeramo selile mubushyuhe bwicyumba, bikomeza kugeza igihe habaye igisubizo kiboneye.

Ni ibihe bintu bigira ingaruka ku gufata amazi ya hydroxypropyl methylcellulose?

Kugumana amazi ya hydroxypropyl methylcellulose HPMC ubwayo ikunze kwibasirwa nimpamvu zikurikira:

1. Guhuza selile ya ether HPMC

HPMC iringaniye, metoxyl na hydroxypropoxyl iragabanijwe neza, kandi igipimo cyo gufata amazi ni kinini.

2. Ubushyuhe bwubushyuhe bwa selulose ether HPMC

Iyo ubushyuhe bwa gel ubushyuhe buri hejuru, niko igipimo cyo gufata amazi kiri hejuru; bitabaye ibyo, gabanya igipimo cyo gufata amazi.

3. Cellulose ether HPMC ibishishwa

Iyo ubwiza bwa HPMC bwiyongereye, igipimo cyo gufata amazi nacyo cyiyongera; iyo ibishishwa bigeze kurwego runaka, kwiyongera k'igipimo cyo gufata amazi bikunda kuba byiza.

Ongeraho umubare wa selile ether HPMC

Umubare munini wa selile ether HPMC wongeyeho, niko igipimo cyo gufata amazi ningaruka nziza yo gufata amazi.

Mu ntera ya 0.25-0,6% yongeyeho, igipimo cyo gufata amazi cyiyongera vuba hamwe no kwiyongera kwinyongera; iyo amafaranga yiyongereye arushijeho kwiyongera, ubwiyongere bwikigero cyo gufata amazi kiratinda.
