Hydroxypropylmethylcellulose (HPMC) ni selile ya selile ikomoka ku masoko karemano nk'ibiti by'ibiti hamwe n'ipamba.Bitewe nimiterere yihariye, harimo gukemura amazi, ubushobozi bwo kubyimba, imiterere yo gukora firime, nibindi, ikoreshwa cyane mubikorwa bitandukanye.Kimwe mu bintu byingenzi ugomba gusuzuma mugihe ukoresheje HPMC nubukonje bwayo, bushobora kugira ingaruka zikomeye kumikorere yabantu batandukanye.Muri iki kiganiro, turaganira ku mpamvu selulose HPMC ifite viscosities zitandukanye zigomba gutoranywa ahantu hatandukanye hakoreshwa, nuburyo viscosity ikwiye ishobora gufasha kunoza imikorere ya HPMC.
Viscosity ni igipimo cyamazi yo kurwanya umuvuduko kandi ni ikintu cyingenzi mugushushanya ibicuruzwa bisaba ibiranga ibintu byihariye.Viscosity igira ingaruka kumikorere ya HPMC kuko igena ubushobozi bwayo bwo gukora geles, ikagira ingaruka kuri pH yumuti, ubunini bwikibiriti, nibindi bintu bifatika.HPMC iraboneka mubyiciro bitandukanye byubwiza, ubwoko bukunze kuba ubukonje buke (LV), ubukonje buciriritse (MV) hamwe nubwiza bwinshi (HV).Buri bwoko bwubwoko bufite intego yihariye kandi burakwiriye kubidukikije.
Ubukonje buke (LV) HPMC
Ubukonje buke HPMC ifite uburemere buke bwa molekile kandi irashobora gushonga byoroshye mumazi.Nubwoko busanzwe bwa HPMC kandi bukoreshwa mubikorwa bitandukanye birimo ibiryo, amavuta yo kwisiga, ubwubatsi na farumasi.LV HPMC irakwiriye cyane kubisabwa bisaba ibisubizo bito kandi biciriritse bikemurwa nka geles zisobanutse, emulisiyo n'amabara.LV HPMC irashobora kandi gukoreshwa kugirango ubuzima bwibiryo burangire, kugabanya syneresi no gutanga imiterere neza.
LV HPMC nayo ikoreshwa cyane mubikorwa byubwubatsi kugirango itezimbere imikorere yibikoresho bishingiye kuri sima nka minisiteri, grut hamwe na tile.Ifasha kugabanya gutakaza amazi muruvange rwa sima, irinda gucika, kandi ishimangira isano iri hagati yibikoresho.LV HPMC nayo ikoreshwa mukongera imbaraga nigihe kirekire cya plasta, stucco nibindi bikoresho bifitanye isano.
Hagati ya Viscosity (MV) HPMC
Hagati ya viscosity HPMC ifite uburemere buke burenze LV HPMC kandi ntibishobora gushonga mumazi.Ubusanzwe ikoreshwa mubisabwa bisaba ibisubizo byibanze cyane nka coatings, langi na wino.MV HPMC ifite uburyo bwiza bwo kugenzura no gukoresha ibintu kuruta LV HPMC, bivamo ubunini bwa firime imwe kandi ihamye.MV HPMC irashobora kandi gukoreshwa murwego rwagutse rwa pH, itanga inyongera zinyuranye kubikorwa bitandukanye.
MV HPMC ikoreshwa cyane mubicuruzwa bikoreshwa mu bya farumasi, nkibinini bisohoka bigenzurwa, kuko bidindiza gusesa bityo bikongerera irekurwa ryibintu bikora.
Viscosity Yinshi (HV) HPMC
Ubukonje bwinshi HPMC ifite uburemere buke bwa molekile yibyiciro bitatu byose kandi ni amazi make ashonga.Ubusanzwe ikoreshwa mubisabwa bisaba kubyimba no gutuza ibintu, nka sosi, cream na geles.HV HPMC ifasha kuzamura imiterere nubwiza bwibicuruzwa, bitanga uburambe bwabakoresha.Irashobora kandi gukoreshwa muguhagarika emulisiyo, kwirinda gutuza no kwagura ubuzima.Byongeye kandi, HV HPMC ikoreshwa kenshi munganda zimpapuro kugirango zongere imbaraga zimpapuro.
mu gusoza
Ubukonje bukwiye bwa HPMC nibyingenzi kugirango uhindure imikorere yayo mubidukikije bitandukanye.LV HPMC ikwiranye nibisabwa bisaba ibisubizo bito kandi biciriritse, mugihe MV HPMC ibereye ibisubizo binini cyane nk'ibara, amarangi na wino.Hanyuma, HV HPMC irakwiriye kubisabwa bisaba kubyimba no gutuza ibintu nka cream, geles hamwe nisosi.Guhitamo neza neza birashobora gufasha kunoza imikorere rusange ya HPMC no kuyikora neza kubikorwa bitandukanye.
