Ikomeye ya virusiHpmcHydroxyPropyl Methyl Cellulose, imikorere yo kugumana amazi. Viscosity nigipimo cyingenzi cyimikorere ya HPMC. Kugeza ubu, abakora ba HPMC bakoresheje uburyo n'ibikoresho bitandukanye kugirango bamenye vicosity ya HPMC. Uburyo nyamukuru burahagije Rotovisko, Hopler, Ubublohde na Brookfield, nibindi
Kubicuruzwa bimwe, ibisubizo bya sscometity byapimwe nuburyo butandukanye buratandukanye cyane, bimwe ndetse nitandukaniro nyinshi. Kubwibyo, mugihe ugereranya vicosi, bigomba gukorwa hagati yuburyo bumwe bwikizamini, harimo ubushyuhe, rotor, nibindi.
Kubunini buranga, ibice byiza, ibyiza byo kugumana amazi. Ibice binini bya selile birahura namazi, ubuso ako kanya bushonga kandi bugakora gel kugirango ukomeze kwishongora, rimwe na rimwe gutoranya ntibishobora guhitana, gushinga igisubizo cyuzuye ibyondo cyangwa agglomerate. Kudakemurwa kwa selile nimwe mubintu byo guhitamo selile. Ibyiza nabyo ni urutonde rwingenzi rwimikorere ya methyl selile. MC kubutaka bumye busaba ifu, amazi make, nibyiza bya 20% ~ 60% ingano yinshi munsi ya 63um. Ibyiza bigira ingaruka ku kuntuHpmcHydroxyPropyl Methyl Cellulose ether. Ubusanzwe mc mubisanzwe ni granular kandi irashobora gushonga byoroshye mumazi adahwitse, ariko umuvuduko wo gusebanya uratinda cyane, bityo ntibikwiye gukoreshwa muri minisiteri yumye. Muri Mortar yumye, MC iratatana hagati yamakuru, yuzuye yuzuye hamwe nibikoresho byo kubunga, kandi gusa nkifu ihagije ishobora kwirinda guhubuka kwa methyl iyo kuvanga amazi. Iyo MC yongeraho amazi kugirango ishonge agglomete, biragoye cyane gutatana no kubicana. MC hamwe nibyiza biteye ubwoba ntabwo ari imyanda gusa, ahubwo bigabanya imbaraga zaho ya minisiteri. Iyo minisiteri yumye yubatswe ahantu hanini, umuvuduko ukiza wa minisiteri yumye yagabanutse cyane, bikavamo gucika intege kubera igihe gitandukanye. Kugirango imashini itera minisiteri, kubera igihe gito cyo kuvanga, igorofa iri hejuru.
Muri rusange, hejuru cyane viscosiya, ingaruka nziza zo kugumana amazi. Ariko, hejuru cyane cyane ni, hejuru yuburemere bwa MC ni, kandi imikorere yo kuvugurura izagabanuka ihuye nimbaraga nimbaraga zubwubatsi. Isumbuye viscosiya, niko ingaruka zibyimbye za minisiteri, ariko ntabwo bigereranyije nubusabane. Hejuru ya virusire, minisiteri itose izakomera, kubaka, imikorere yisi ifatanye no gufunga cyane kubikoresho byibanze. Ariko ntabwo ari byiza kongera imbaraga zuburyo bwa minisiteri itose. Mugihe cyo kubaka, imikorere yo kurwanya sag iragaragara. Ibinyuranye nibyo, bamwe mu bayobe nke ariko bahinduwe methyl bahanganye na Methyl bafite imikorere myiza mugutezimbere imbaraga za minisiteri itose.
Ubundi bushya bwa selile yongewe kuri minisiteri, imikorere yo kugumana amazi meza, hejuru ya virusire, imikorere yo kugumana amazi meza.
Ubukonje bwa HPMC kandi bufite ingaruka runaka mumazi yo kugumana amazi, muri rusange, kubuza urusyo hamwe nibyiza bitandukanye bya Methyl, mugihe kimwe cyo kwiyongera, ingaruka nziza yo kwiyongera, ingaruka nziza zamazi nibyiza.
Kugumana amazi ya HPMC nabyo bifitanye isano n'ubushyuhe bwo gukoresha, kandi kugumana amazi ya methyl selile bigabanuka hamwe no kuzamuka kw'ubushyuhe. Ariko muburyo bwo gusaba ibikoresho, ibidukikije byinshi byimishinga yumye akenshi bizaba mubushyuhe bwinshi (hejuru ya dogere 40) munsi yubwubatsi bushyushye, nko guhindagurika kwubaka urukuta rwinshi, akenshi byihutisha gukomera kwa sima na manceri yumye. Kugabanuka kw'igipimo cyo kugumana amazi biganisha ku byiyumvo bigaragara ko twubaka no kurwanya ibisiga bigira ingaruka. Muri ubu buryo, bigabanya imbaraga zubushyuhe buba mubi cyane. Nubwo kongeramo methyl hydroxyyeryl ether ifatwa nkibanze yiterambere ryikoranabuhanga, ishingiye ku iterambere ryikoranabuhanga, kwishingikiriza kubushyuhe bizakomeza kuganisha ku miterere yimitungo ya pertar yumye. Ndetse no kwiyongera kwa methyl hydroxyyeryl dosage ya selile (formulaire yo mu mpeshyi), kubaka no kurwanya ibisiga kandi ntibishoboka ntibishobora guhaza ibikenewe. Binyuze muburyo bumwe bwihariye bwa MC, nko kongera urwego rworoshye, ingaruka zo kugumana amazi ya MC zirashobora gukomeza ingaruka nziza munsi yubushyuhe bwinshi, kugirango rishobore gutanga imikorere myiza mubihe bibi.
