Nigute ushobora kugerageza ububobere bwa hydroxypropyl methylcellulose?

Hydroxypropyl methylcellulose yo kubaka ikeneye kwirinda kwinjira mu mazi mu rukuta, kandi kugumana amazi akwiye muri minisiteri birashobora gutuma sima itanga umusaruro mwiza ku mazi n’amazi. Hydroxypropyl methylcellulose Ubukonje bwa selilose muri minisiteri buragereranijwe neza, uko ubukonje bwinshi, niko gufata amazi meza ya hydroxypropyl methylcellulose.

Iyo ubuhehere buri muri hydroxypropyl methylcellulose bumaze kuba mwinshi, kubika amazi ya hydroxypropyl methylcellulose bizagabanuka, ibyo bikaba bizatuma igabanuka ryubwubatsi bwa hydroxypropyl methylcellulose. Tumenyereye kandi ibintu bishoboka cyane gukora amakosa. Tugomba guhora dukomeza gushya kandi tuzakira ibisubizo bitunguranye.

Ikigaragara kigaragara ni ikimenyetso cyingenzi cya hydroxypropyl methylcellulose. Uburyo busanzwe bwo kugena ni viscometrie izenguruka, capillary viscometrie no kugwa kwizuba ryizuba.

Mubihe byashize, uburyo bwo kumenya hydroxypropyl methylcellulose bwari capillary viscometry, ukoresheje viscometer ya Ubbelohde. Mubisanzwe igisubizo cyo kwiyemeza nigisubizo cyamazi ya 2, kandi formula ni: V = Kdt. V yerekana ububobere, igice ni, K ni ihoraho rya viscometer, d igereranya ubucucike bwubushyuhe buhoraho, t bivuga igihe kuva hejuru kugeza hasi unyuze kuri viscometer, igice ni icya kabiri s. Ubu buryo buragoye gukora, kandi niba hari ibintu bitangirika, biroroshye gutera amakosa, kandi biragoye kumenya ubwiza bwa hydroxypropyl methylcellulose.

Ikibazo cyo gusiba kole yubwubatsi nikibazo kinini gihura nabakiriya. Mbere ya byose, ikibazo cyibikoresho fatizo bigomba gusuzumwa mugusiba kole yubaka. Impamvu nyamukuru yo gusibanganya kole yubaka ni inzoga za polyvinyl (PVA) na hydroxypropyl methylcellulose (HPMC). biterwa no kudahuza. Icya kabiri, ni ukubera ko igihe cyo gukurura kidahagije; mubyongeyeho, imikorere yibyibushye ya kole yubwubatsi ntabwo ari nziza.

Muri kole yubaka, hydroxypropyl methylcellulose (HPMC) igomba gukoreshwa ako kanya, kubera ko hydroxypropyl methylcellulose (HPMC) ikwirakwizwa mumazi gusa nta gushonga. Hafi yiminota 2, ubwiza bwamazi bugenda bwiyongera buhoro buhoro, bukora colloid ibonerana.

Ibicuruzwa bishyushye, iyo bihuye namazi akonje, birashobora gukwirakwira vuba mumazi ashyushye bikabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ibishishwa bizagaragara buhoro buhoro kugeza igihe bibumbiye mu mucyo. Umubare usabwa wa hydroxypropyl methylcellulose (HPMC) wongeyeho kole ni 2-4kg.

Hydroxypropyl methylcellulose (HPMC) ifite imiti ihamye ya chimique, irwanya indwara ya mildew, hamwe no gufata amazi meza muri kole yubwubatsi, kandi ntabwo ihindurwa nimpinduka zagaciro ka pH. Irashobora gukoreshwa hamwe nubwiza buri hagati ya 100.000 S na 200.000 S. Ariko mubikorwa, uko ubukonje buri hejuru, nibyiza. Ubukonje buragereranywa nimbaraga zumubano. Iyo hejuru ya viscosity, imbaraga nkeya. Mubisanzwe, ubwiza bwa 100.000 S burakwiriye.
