Hydroxypropyl methylcellulose (HPMC) muri minisiteri ivanze

Uruhare rwaHPMC muri minisiteri ivanze

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 nkibikoresho birinda sima ya sima kandi nkibisubira inyuma kugirango ibishishwa bishoboke.Hydroxypropyl-Methyl Cellulose HPMC Cellulose ifite ubushobozi bwo gutanga amazi nkigisubizo kiboneye cyongera imikorere ya dab kandi ikongerera igihe cyakazi.Ibi bituma sesame idacika vuba nyuma yo gusiga no kongera imbaraga nyuma yo gukama..Acide Hydrochloric nigikorwa cyingenzi cya HPMC kugirango hydrolyze selulose, kandi ikora ibicuruzwa byinshi mubushinwa.Ibintu bigira ingaruka mbi zirimo HPMC yongeweho, ubwiza bwa HPMC, ubwiza bwibice hamwe nubushyuhe bwibidukikije.

Uruhare runini rwa HPMC mu kuvanga amazi rugaragarira cyane cyane mu bintu bitatu: kimwe ni ubushobozi bwiza bwo gufata amazi, ikindi ni ingaruka ku guhindagurika no guhindura ibyiyumvo byo kuvanga amazi, naho ubundi ni imikoranire na sima.Ingano ya selulose ether iterwa no gufata amazi na substrate, ibigize umucanga, ubunini bwurwego, gukenera amazi mugisubizo, nigihe cyo guteranya ibintu.

Ibintu bigumana ubuhehere bigira ingaruka kuri selile ya hydrolyzed harimo ubwiza bwa pulp, ubwinshi bwinyongera, ubwiza bwubushyuhe n'ubushyuhe.Umubyimba mwinshi wa selile, nibyiza birwanya amazi.Viscosity nikintu cyingenzi cyimikorere ya HPMC.Kubicuruzwa bimwe, ibisubizo bya viscosity byapimwe nuburyo butandukanye biratandukanye cyane, ndetse bimwe bigera no kuri geometrike.Kubwibyo, kugereranya viscosities, bigomba gukorwa hagati yuburyo bumwe bwikizamini, harimo ubushyuhe, spindle, nibindi.

Muri rusange, hejuru yubukonje, niko gukora neza bitarimo amazi.Ariko uko kwiyongera kwijimye, HPMC, hejuru yuburemere bwa molekile, niko kugabanuka kwimiterere, igisubizo kirakomeye, kandi nibintu bigira ingaruka mbi.Iyo hejuru yubukonje, ningaruka zo kubyibuha mugisubizo, ariko ntabwo bihuye neza nikigereranyo.Iyo hejuru yubukonje bwinshi, butose kandi burushijeho kubona igisubizo, mugihe cyubaka, byerekana imbaraga nyinshi imbere yibibabi bifatanye nibikoresho.Ariko kongeramo imbaraga zububiko kuri minisiteri itose ubwayo ntabwo bizafasha.Iyo nyubako zombi zubatswe, byagaragaye ko umurimo wo kurwanya imibu wabuze.Ibinyuranye, aside-methacrylic yahinduwe nyuma ya acide methacrylic, mugihe selile itezimbere igisubizo gitose nimbaraga zubaka, ifite ibintu byiza cyane.
