Amababi avanze neza ni sima, igiteranyo cyiza, kuvanga, amazi nibindi bice byagenwe ukurikije imikorere.Ukurikije igipimo runaka, nyuma yo gupimwa no kuvangwa muri sitasiyo ivanga, ijyanwa aho ikoreshwa n’ikamyo ivanga, hanyuma igashyirwa mu buryo budasanzwe Uruvange rutose rubikwa muri kontineri kandi rugakoreshwa mu gihe cyagenwe.
Hydroxypropyl methylcellulose ikoreshwa nkigikoresho cyo kubika amazi no kubika minisiteri ya sima kugirango minomeri ishoboke.Ikoreshwa nka binder mugupompa plaster, itezimbere ikwirakwizwa kandi ikongerera igihe cyakazi.Imikorere yo gufata amazi ya hydroxypropyl methylcellulose HPMC irinda guturika guturika bitewe no gukama vuba nyuma yo kuyisaba, kandi ikongerera imbaraga nyuma yo gukomera.Kubika amazi nigikorwa cyingenzi cya hydroxypropyl methylcellulose HPMC, kandi nigikorwa kandi benshi mubakora uruganda rukora amavuta avanze na minisiteri.Ibintu bigira ingaruka ku gufata amazi ya minisiteri ivanze n’amazi arimo ingano ya HPMC yongeyeho, ubwiza bwa HPMC, ubwiza bw’ibice, hamwe nubushyuhe bw’ibidukikije.
Uruhare rukomeye rwa hydroxypropyl methylcellulose HPMC muri minisiteri ivanze cyane cyane ifite ibintu bitatu, kimwe nubushobozi buhebuje bwo gufata amazi, ikindi ni ingaruka ku guhuza hamwe na thixotropy ya minisiteri ivanze, naho icya gatatu ni imikoranire na sima.Ingaruka yo gufata amazi ya selile ya selile biterwa no kwinjiza amazi kurwego rwibanze, imiterere ya minisiteri, ubunini bwikigero cya minisiteri, amazi akenerwa na minisiteri, nigihe cyo kugenera ibikoresho.Iyo hejuru ya hydroxypropyl methylcellulose igaragara neza, niko gufata amazi neza.
Ibintu bigira ingaruka ku kugumana amazi ya minisiteri ivanze harimo selile ya ether viscosity, umubare wongeyeho, ubwiza bwibice no gukoresha ubushyuhe.Ninini cyane ya selulose ether, niko gukora neza amazi.Viscosity nikintu cyingenzi cyimikorere ya HPMC.Kubicuruzwa bimwe, ibisubizo bya viscosity byapimwe nuburyo butandukanye biratandukanye cyane, ndetse bimwe byikubye kabiri itandukaniro.Kubwibyo, mugihe ugereranije viscosity, bigomba gukorwa hagati yuburyo bumwe bwo gupima, harimo ubushyuhe, rotor, nibindi.
Muri rusange, uko ubukonje buri hejuru, ningaruka nziza yo gufata amazi.Nyamara, uko hejuru yubukonje nuburemere bwa molekuline ya HPMC, kugabanuka gukwiranye kwayo bizagira ingaruka mbi kumbaraga no mumikorere yubwubatsi.Iyo hejuru yubukonje, niko bigaragara ingaruka zo kubyimba kuri minisiteri, ariko ntabwo ihwanye neza.Iyo hejuru yubusembwa, niko amabuye atose azarushaho kuba meza, ni ukuvuga mugihe cyubwubatsi, bigaragarira nko kwizirika kuri scraper no gufatira hejuru kuri substrate.Ariko ntabwo ari byiza kongera imbaraga zimiterere ya minisiteri yonyine.Mugihe cyo kubaka, imikorere irwanya sag ntabwo igaragara.Ibinyuranye na byo, hydroxypropyl methylcellulose yahinduwe hamwe na viscosity yo hagati kandi ntoya ifite imikorere myiza mugutezimbere imbaraga zububiko bwa minisiteri.
Umubare munini wa selile ether HPMC wongeyeho mumashanyarazi avanze, niko imikorere myiza yo gufata amazi, hamwe nubukonje bwinshi, niko imikorere yo gufata amazi ari nziza.Ubwiza nabwo ni indangagaciro yingenzi ya hydroxypropyl methylcellulose.
Ubwiza bwa hydroxypropyl methylcellulose nabwo bugira ingaruka runaka kubigumana byamazi.Muri rusange, kuri hydroxypropyl methylcellulose hamwe nubwiza bumwe ariko bwiza butandukanye, nibyiza nibyiza nibyiza amazi yo gufata amazi nibyiza.
Muri minisiteri ivanze neza, ingano ya selile ya ether HPMC ni mike cyane, ariko irashobora kunoza cyane imikorere yubwubatsi bwa minisiteri ivanze, kandi ninyongera nyamukuru igira ingaruka kumyubakire ya minisiteri.Guhitamo neza hydroxypropyl methylcellulose ifite uruhare runini mugutezimbere imikorere ya minisiteri ivanze.
