Nigute ushobora guhitamo hydroxypropyl methylcellulose?

Ni irihe tandukaniro riri hagatihydroxypropyl methylcellulose(HPMC) hamwe na S?

1. HPMC igabanijwe mubwoko bwihuse nubwoko bwo gutatanya byihuse

Ubwoko bwa HPMC bwihuta bwongeweho inyuguti ya S. Mugihe cyo gukora, glyoxal igomba kongerwamo.

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

2. Hamwe na S cyangwa idafite S, ibiranga biratandukanye

Gukwirakwiza vuba HPMC ikwirakwira vuba mumazi akonje ikabura mumazi. Muri iki gihe, amazi ntagira ubwiza, kubera ko HPMC ikwirakwizwa mu mazi gusa, kandi nta gushonga nyako. Nyuma yiminota igera kuri ibiri, ubwiza bwamazi bugenda bwiyongera buhoro buhoro, bigakora amazi meza. Umuyoboro mwinshi.

HPMC ako kanya irashobora gukwirakwira vuba mumazi ashyushye kuri 70 ° C. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ubukonje bugaragara buhoro buhoro kugeza igihe habaye ibibyimba bisobanutse neza.

3. Hamwe na S cyangwa idafite S, intego iratandukanye

HPMC ako kanya irashobora gukoreshwa gusa muri poro ya poro na minisiteri. Mubikoresho byamazi, ibifuniko nibikoresho byoza, guhuzagurika bizabaho kandi ntibishobora gukoreshwa.

Gukwirakwiza vuba HPMC ifite uburyo bwinshi bwo gusaba. Irashobora gukoreshwa mu ifu yuzuye, minisiteri, kole yamazi, irangi, hamwe no gukaraba ibicuruzwa nta kubuza.

Uburyo bwo gusesa

1. Fata umubare ukenewe wamazi ashyushye, uyashyire mubikoresho hanyuma ubishyuhe hejuru ya 80 ° C, hanyuma wongereho ibicuruzwa buhoro buhoro. Cellulose ireremba hejuru y'amazi, ariko igenda ikwirakwira buhoro buhoro kugirango ibe imwe. Hisha igisubizo hamwe.

2. Cyangwa 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.

4. Ongeramo selile buhoro kandi buringaniye mubushyuhe bwicyumba, hanyuma ukomeze kubyutsa mugihe cyo kongeramo kugeza 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. Cellulose ether HPMC ubutinganyi

HPMC yakiriye kimwe ifite gukwirakwiza imitekerereze ya hydroxypropoxy hamwe no gufata amazi menshi.

2. Cellulose ether HPMC ubushyuhe bwa gel

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 viscosity igeze kurwego runaka, kwiyongera k'igipimo cyo gufata amazi bikunda kuba byoroheje.

Cellulose ether HPMC yongeyeho

Ninshi wongeyeho selile ya ether HPMC, niko igipimo cyo gufata amazi ningaruka nziza yo gufata amazi.

Mu ntera ya 0.25-0,6%, igipimo cyo gufata amazi cyiyongera vuba hamwe no kwiyongera kwinshi; iyo amafaranga yiyongereye arushijeho kwiyongera, kwiyongera kwikigero cyo gufata amazi bigenda gahoro.
