Nibihe bintu bigira ingaruka kumasoko yo kugumana amazi ya hydroxyPropyl methylcellse?

Isumbuye viscosiya za hydroxypropyl methylcellse, imikorere yo kugumana amazi. Viscosity nigipimo cyingenzi cyimikorere ya HPMC. Kugeza ubu, abakora ba HPMC bakoresha uburyo n'ibikoresho bitandukanye kugirango bapime vicosity ya HPMC. Uburyo nyamukuru ni guhosha Rotovisko, hoppler, Ubublohde na Brookfield.

Kubicuruzwa bimwe, ibisubizo bya viscosity byapimwe nuburyo butandukanye buratandukanye cyane, ndetse bamwe ndetse no kwikundwa. Kubwibyo, mugihe ugereranya vicosi, menya neza kubikora hagati yuburyo bumwe bwikizamini, harimo ubushyuhe, rotor, nibindi.

Kubunini buranga, ibice byiza, ibyiza byo kugumana amazi. Nyuma yibice binini bya selile bihura namazi, ubuso burashonga ako kanya kugirango bugire gel, izungura ibikoresho kugirango birinde molekile y'amazi. . Bigiraho ingaruka cyane ingaruka zo kugumana amazi ether, kandi yonyine ni kimwe mubintu byo guhitamo filife. Ibyiza nabyo ni urutonde rwingenzi rwimikorere ya methyl selile. MC ikoreshwa mu myambaro yumye isabwa kuba ifu, hamwe namazi make, kandi ibyiza bisaba kandi 20% kugeza kuri 60% yubunini butari munsi ya 63um. Ubukonje bugira ingaruka ku bushobozi bwa hydroxyproppopyl methylcellse ether. Ubusanzwe mc mubisanzwe ni granular, kandi biroroshye gushonga mumazi nta buhinzi bukabije, ariko igipimo cy'imivugo kiratinda cyane, bityo ntibikwiriye gukoreshwa muri minisiteri yumye. Mu myambaro yumye minisiteri, MC ikwirakwizwa mubikoresho bifatika nko guteranya, filile nziza na sima. Gusa ifu ihagije irashobora kwirinda agglomeration ya methyl selile mugihe uvanze namazi. Iyo MC yongeweho amazi kugirango ishonge agglomerates, biragoye kubitana no gushonga. MC hamwe nibyiza bya Coarser ntabwo bisesagura gusa, ahubwo bigabanya imbaraga zaho za minisiteri. Iyo ifu yumuntu wumye wubatswe ahantu hanini, umuvuduko ukiza wifu yumye yagabanutse cyane, kandi imitsi ya iboneka kubera ibihe bitandukanye bikiza. Kuberako rarir mirtar akoresheje iyubakwa ryubuka, kubera igihe gito cyo gukata, ibyiza birasabwa kuba hejuru.

Muri rusange, hejuru cyane viscosiya, ingaruka nziza zo kugumana amazi. Ariko, hejurus viscosiya hamwe nuburemere bukomeye bwa MC, kugabanya igabana muke, bikagira ingaruka mbi ku mbaraga nimbaraga za minisiteri. Isumbuye viscosiya, niko ingaruka zijimye za minisiteri, ariko ntabwo aringaniye. Hejuru cyane viscosiya, niko minisiteri itose izaba. Mugihe cyo kubaka, izakomeza ku gishushanyo kandi ifite umutsima mwinshi kuri substrate. Ariko ntibikora bike kugirango wongere imbaraga zuburyo bwa minisiteri itose. Mugihe cyo kubaka, imikorere yubuzima bwo kurwanya sta-swag but ntabwo bigaragara. Ibinyuranye nibyo, bamwe mu ruswa ruto ariko bahinduwe methyl bahanganye na selile bafite imikorere myiza mugutezimbere imbaraga za minisiteri itose.

Umubare munini wa selile wongeyeho muri minisiteri, imikorere yo kugumana amazi, hejuru ya virusire, imikorere yo kugumana amazi.

Ibyiza bya HPMC nabyo bigira uruhare runini mu kugumana amazi. Muri rusange, kuri Methyl selile ya exeches hamwe nibyiza bitandukanye, nibyiza kongereranyo, ibyiza byiza, ingaruka nziza y'amazi.

Kugumana amazi ya HPMC nabyo bifitanye isano n'ubushyuhe bwakoreshejwe, kandi ugusuka amazi ya methyl selile bigabanuka hamwe no kwiyongera k'ubushyuhe. Ariko, muburyo bufatika bwo gusaba, minisiteri yumye ikunze gukoreshwa kurubuga rushyushye ku bushyuhe bwo hejuru (hejuru ya dogere 40) mu bihe byinshi, nko kwihutisha gukiza sima, bikomera kuri minisiteri yumye. Igitonyanga cyo kugumana n'amazi cyateje imyumvire isobanutse ko abakozi bashinzwe no guturika bigira ingaruka, kandi birakomeye cyane kugirango bigabanye ingaruka zimiterere yubushyuhe mubihe nkibi. Nubwo methyl hydroxyyeryl selile ether kuri ubu ifatwa nkaho iri ku isonga ryiterambere ryikoranabuhanga, kwishingikiriza ku bushyuhe burashobora kuganisha ku guca intege imikorere ya minite. Nubwo ingano ya methyl hydroxyyeryl selile (formulaire yimpeshyi) yiyongereye, ibikorwa no kurwanya ibikorwa no kurwanya ibitaramo ntibigishobora kuzuza ibikenewe. Binyuze muburyo bumwe bwihariye, nko kongera urwego rwo guhindura, MC rushobora kugumana ingaruka zamazi meza kubushyuhe bwo hejuru, kugirango bushobore gutanga imikorere myiza mubihe bibi.
