Ni irihe tandukaniro riri hagatihydroxypropyl methylcellse(HPMC) hamwe cyangwa idafite s?
1. HPMC igabanijwemo ubwoko bwihuse kandi bwihuse
HPMC ikwirakwiza ubwoko bwihagije hamwe ninyuguti s. mugihe cyo gukora, Glyoxal igomba kongerwaho.
Ubwoko bwa HPMC ntabwo yongera amabaruwa ayo ari yo yose, nka "100000" ni "100000 vicosity itara mu bwoko bwa HPMC".
2. Hamwe cyangwa udafite s, ibiranga biratandukanye
Gukwirakwiza byihuse abatatana HPMC vuba aha mumazi akonje kandi uzimira mumazi. Muri iki gihe, amazi adafite ubuyobe, kuko HPMC yatatanye gusa mumazi gusa, kandi nta guseswa nyabyo. Nyuma yiminota ibiri, visosity yamahoro yiyongera buhoro buhoro, gukora amazi akomeye. Umubyimba.
Ako kanya HPMC irashobora gutatanya vuba mumazi ashyushye nka 70 ° C. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, viscosity igaragara buhoro kugeza igihe yasunitswe neza.
3. Hamwe cyangwa udafite s, intego iratandukanye
Ako kanya HPMC irashobora gukoreshwa gusa mubutaka bwa Putty na minisiteri. Mu buryo butagira amazi, amatara no gusukura ibikoresho, guhiga bizaba bizabaho kandi ntibishobora gukoreshwa.
Gukwirakwiza vuba HPMC ifite uburyo butandukanye. Irashobora gukoreshwa muri powder ifu, minisiteri, kole ya mazi, irangi, irangi, kandi koza ibikomokaho nta binyuranye.
Uburyo bwo kuvura
1. Fata umubare ukenewe wamazi ashyushye, ubishyire mu kintu no gushyushya hejuru kugeza kuri 80 ° C, hanyuma wongere buhoro buhoro ibi bicuruzwa bidakabije. Ubugari bureremba hejuru y'amazi mbere, ariko buhoro buhoro iratatana kugirango akore imyenda imwe. Gukonjesha igisubizo no kubyutsa.
2. Cyangwa ubushyuhe 1/3 cyangwa 2/3 by'amazi ashyushye kugeza hejuru ya 85 ° C, ongeraho ubutunganire bw'amazi ashyushye, hanyuma ongeraho umubare usigaye w'amazi, komeza ukomeze, kandi ukonje kuvanga kuvanze.
3. Cekwi ifite numero ya mesh ugereranije, kandi ibaho nkinco ntoya imwe muri ifu imwe imwe, kandi irashonga vuba iyo ihuye namazi kugirango amazi asabwa.
4. Ongeraho selile gahoro gahoro kandi kuri ubushyuhe bwicyumba, kandi ukomeze kubyutsa mugihe cyo kongeramo igihe cyo kongeramo kugeza igihe igisubizo kiboneye cyatanzwe.
Ni ibihe bintu bigira ingaruka kumazi ya hydroxyproppopyl methylcellse?
Kugumana amazi ya hydroxyPropyl methylcellsellse ibicuruzwa ubwabyo bikunze kwibasirwa nibintu bikurikira:
1. Cellulose Ether Hpmc homogeneity
HPMC yegeranye nayo ifite uburyo bumwe bwo gukwirakwiza uburyo na hydroxyPropoplexy n'amatsinda menshi.
2. Cekwil Ether Hpmc Ubushyuhe bwa Gel
Hejuru yubushyuhe bwa gel, igipimo cyo kugumana amazi; Bitabaye ibyo, hagamijwe kugabana amazi.
3. Ubugari bwa ether mpmc viscosity
Iyo virusi ya HPMC yiyongera, umubare wogumana amazi nawo uriyongera; Iyo ubushyuhe bugeze ku rwego runaka, kwiyongera kw'ibipimo by'amazi bikunda kwitonda.
Cellulose Ether HPMC Amafaranga yongeyeho
Inini nini yongeweho ya selile ether hpmc, igipimo cyo kugumana amazi ningaruka nziza yo kugumana amazi.
Mu rwego rwa 0.25-0.000.6%, urugero rw'amazi yogumana amazi yongera vuba hamwe no kwiyongera kw'amafaranga yiyongera; Iyo amafaranga yo kwigomeka yiyongera, uburyo bwo kongera kugumana amazi buhinduka buhoro.
