Ikigaragara kigaragara ni ikimenyetso cyingenzi cya hydroxypropyl methylcellulose, uburyo bukoreshwa muburyo bwo gupima burimo kuzenguruka viscometrie, capillary viscometry na viscometrie.
Hydroxypropyl methylcellulose yabanje gupimwa hifashishijwe capillary viscometrie ikoresheje viscometer ya Ubbelohde. Mubisanzwe igisubizo cyo gupima nigisubizo cyamazi ya 2, formula ni: V = Kdt. V yerekana ububobere, K ni ihoraho rya viscometer, d igereranya ubucucike ku bushyuhe buhoraho, t bivuga igihe kuva hejuru kugeza hepfo ya viscometer, igice ni icya kabiri, ubu buryo buragoye gukora kandi burakora biroroshye gutera Ikibi, kandi biragoye gutandukanya ubwiza bwa hydroxypropyl methylcellulose.
Ikibazo cyo gusiba kole yubwubatsi nikibazo kinini gihura nabakiriya. Mbere ya byose, ikibazo cyibikoresho fatizo bigomba gutekerezwa kubikorwa byubaka. Impamvu nyamukuru yubaka glue yubatswe nuko inzoga za polyvinyl (PVA) na hydroxypropyl methylcellulose (HPMC) zidahuye. Impamvu ya kabiri nuko igihe cyo gukurura kidahagije, kandi kubyimbye kwimikorere ya kole yubwubatsi ntabwo ari byiza.
Hydroxypropyl methylcellulose (HPMC) yubuvumbuzi bwa none igomba gukoreshwa mububiko bwubwubatsi, kubera ko hydroxypropyl methylcellulose (HPMC) ikwirakwizwa mumazi kandi ntishobora gushonga rwose, kandi ubwiza bwamazi bwiyongera buhoro buhoro muminota igera kuri 2, bigakora Transparent viscous colloid .
Iyo ibicuruzwa bishushe bishyushye bivanze hamwe mumazi akonje, bizahita bikwirakwira mumazi ashyushye kandi bizimire mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ibishishwa bizagaragara buhoro buhoro kugeza igihe ibinyabuzima bibonerana biboneye. Hydroxypropyl mubyuma byubaka Igipimo gisabwa cya HPMC ni 2-4kg.
Hydroxypropyl methylcellulose (HPMC) ifite imiti ihamye yimiti, irwanya indwara yoroheje kandi ikagumana amazi meza mubikoresho byubaka, kandi ntibiterwa nimpinduka za pH. Irashobora gukoreshwa kuva 100.000 S kugeza 200.000 S, ariko uko ubukonje buringaniye mubikorwa, nibyiza, kandi ibishishwa bigereranywa nimbaraga zo guhuza. Iyo hejuru ya viscosity, niko imbaraga zigabanuka, mubisanzwe ubwiza bwa 100.000 S burakwiriye.
