1. HPMC igabanijwe muburyo bwihuse nubwoko bukwirakwiza vuba.
Ubwoko bwa HPMC bwihuse butandukanya inyuguti S nkumugereka. Glyoxal igomba kongerwamo mugihe cyo gukora.
Ubwoko bwa HPMC bwihuta ntabwo bwongera inyuguti iyo ari yo yose, nka "100000 ″ bisobanura" 100000 viscosity yihuta-HPMC ".
2. Hamwe na S cyangwa idafite S, ibiranga biratandukanye
Gukwirakwiza vuba HPMC ikwirakwira vuba mumazi akonje ikabura mumazi. Amazi ntagifite ubwiza muri iki gihe kuko HPMC ikwirakwizwa mumazi gusa kandi ntabwo yashonga. Nyuma yiminota igera kuri ibiri, ubwiza bwamazi bugenda bwiyongera buhoro buhoro, bigakora amazi meza. Umuyoboro mwinshi.
HPMC ako kanya irashobora gukwirakwizwa 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, amarangi nibikoresho byogusukura, ibice bishobora kubaho kandi ntibikoreshwa.
Gukwirakwiza vuba HPMC ifite uburyo bwinshi bwo gusaba. Irashobora gukoreshwa mubifu ya poro, minisiteri, kole yamazi, irangi, nibikoresho byogusukura nta kubuza.
uburyo bwo gusesa
1. Fata umubare ukenewe wamazi ashyushye, shyira mubintu hanyuma ubishyuhe hejuru ya 80 ℃, hanyuma wongereho buhoro buhoro iki gicuruzwa ukoresheje buhoro. Cellulose ireremba hejuru y'amazi ubanza, ariko igenda ikwirakwira buhoro buhoro. Hisha igisubizo mugihe ukangura.
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, ubyuke ubudahwema, hanyuma ukonje imvange yavuyemo.
3. Cellulose ifite ubunini buke bwa mesh kandi ibaho nkibice bito bito byifu imwe. Irashonga vuba iyo ihuye namazi kugirango ikore neza.
4. Ongeramo selile buhoro kandi buringaniye mubushyuhe bwicyumba, ubyuke kugeza igihe igisubizo kiboneye 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 ibitsina bya selile ether HPMC
Amatsinda ya HPMC yakozwe hamwe na hydroxypropoxy amatsinda aragabanijwe kandi afite amazi menshi.
2. Cellulose ether HPMC ubushyuhe bwa gel
Iyo ubushyuhe bwa gel butwara ubushyuhe bwumuriro, niko igipimo cyo gufata amazi kiri hejuru; muburyo bunyuranye, hasi igipimo cyo gufata amazi.
3. Viscosity ya selulose ether HPMC
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
Umubare munini wa selile ether HPMC wongeyeho, niko igipimo cyo gufata amazi ningaruka nziza yo gufata amazi.
Mu ntera ya 0,25-0,6%, igipimo cyo gufata amazi cyiyongera vuba uko amafaranga yiyongera yiyongera; iyo amafaranga yinyongera arushijeho kwiyongera, kwiyongera kwikigero cyo gufata amazi biratinda.
