Ether ya selile, cyane cyane hydroxypropyl methylcellulose (HPMC), ninyongera yingenzi ikoreshwa munganda zinyuranye kugirango ikore neza cyane, ifata amazi menshi, nubushobozi bwo kongera ubukonje. Muri iki kiganiro, tuzasesengura isesengura ryimbitse ryimiterere ya thixotropy ya selulose ether, cyane cyane twibanda kuri HPMC.
Kubyimba ni umutungo wibanze wa selulose ether, bivuga ubushobozi bwibintu byongera ubwiza bwumuti cyangwa gutatanya. HPMC yerekana kubyimbye cyane, bivuze ko ishobora kongera cyane ububobere ndetse no mubutumburuke buke. Uyu mutungo wifuzwa cyane mubisabwa byinshi, nk'ibiti, ibifuniko, n'ibicuruzwa byita ku muntu ku giti cye, aho bisabwa kugira ububobere buke kugira ngo bikore neza.
Kimwe mu byiza byingenzi bya HPMC nubushobozi bwayo bwo gufata amazi menshi. Kubika amazi bivuga ubushobozi bwibintu bigumana amazi muri sisitemu, ndetse no mubushyuhe bwinshi cyangwa imbere yandi mashanyarazi. HPMC ikora imiterere isa na gel iyo ihinduwe, ifasha kugumana molekile zamazi no kwirinda guhumeka cyane. Uyu mutungo ni ingenzi cyane mu nganda nko kubaka no kuvanga-minisiteri yumye, aho kubungabunga ibimera ari ngombwa kugirango amazi meza kandi akire ibikoresho.
Ubwiyongere bwiyongera butangwa na selile ether, nka HPMC, butanga inyungu nyinshi mubikorwa bitandukanye. Mu nganda zubaka, HPMC ikoreshwa muburyo bwa sima kugirango itezimbere imikorere kandi ikumire amacakubiri. Ubukonje bukabije bwibisubizo bya HPMC butuma igenzurwa neza mugihe cyo gusaba, kwemeza gukwirakwizwa kimwe no kwirinda gutuza ibice. Mu buryo nk'ubwo, mu nganda zo gusiga amarangi, HPMC yongewe ku mwenda kugirango yongere ubwiza bwayo, bivamo gukwirakwizwa neza no kugabanuka gutonyanga.
Byongeye kandi, imiterere ya thixotropique ya selile ether ni ikintu cyingenzi tugomba gusuzuma. Thixotropy bivuga umutungo wibikoresho kugirango ugaragaze impinduka zidasubirwaho mubwiza iyo ushyizeho umwete. Mumagambo yoroshye, iyo imbaraga zogosha zashyizwe mubikorwa, ibikoresho biba bike cyane, byemerera gukoreshwa byoroshye, kandi iyo bihagaze, bisubira muburyo bwambere bwijimye. Uyu mutungo ufite akamaro kanini mubisabwa nka kawusi, kashe, hamwe namavuta ya farumasi, aho bikenewe gutangwa no gukwirakwiza byoroshye. Imyitwarire ya HPMC itanga uburyo bworoshye bwo gukoresha no guhanagura neza hejuru yimiterere, mugihe gikomeza ubwiza bukenewe bwo gufatira hamwe no gufunga ibimenyetso.
Kugirango winjire cyane mubyimbye na thixotropy ya selulose ether, ubushakashatsi nisesengura birakorwa. Ubuhanga butandukanye, harimo gupima imvugo, bukoreshwa mugusuzuma ubwiza, guhangayika, hamwe nimyitwarire ya thixotropique ya selile ya ether ibisubizo. Ubu bushakashatsi bufasha mu gusobanukirwa isano iri hagati yubushuhe, ubushyuhe, nigipimo cyogosha kumubyimba na thixotropy ya selile ya ether.
Mu gusoza, selile ether, cyane cyane HPMC, yerekana kubyimbye cyane, kubika amazi menshi, no kongera ubukonje mubikorwa bitandukanye. Ubushobozi bwayo bwo gutanga imyitwarire ya thixotropique ituma yongerwaho agaciro kubicuruzwa aho byoroshye gukoreshwa hamwe nubwiza bwinshi busabwa icyarimwe. Kugirango usobanukirwe byimazeyo kubyimbye na thixotropy ya selulose ether, isesengura ryinshi nubushakashatsi birakorwa, bikarushaho guteza imbere inganda.
