Kubaka hydroxypropyl methyl selulose idasanzwe kugirango wirinde kwinjirira mu rukuta, bizaba ari urugero rukwiye rw’amazi ashobora kuguma muri sima ya minisiteri bitanga umusaruro mwiza mu mazi kandi uruhare rwa hydroxypropyl methyl selulose muri minisiteri rushobora kugereranywa nubwiza, hejuru ya viscosity ya hydroxypropyl methyl selulose kubika amazi bizaba byiza.
Iyo ubuhehere bwa hydroxypropyl methyl selulose bumaze kuba bwinshi, kubika amazi ya hydroxypropyl methyl selulose bizagabanuka, kandi bizahita biganisha ku iyubakwa rya hydroxypropyl methyl selulose. Tumenyereye kandi ibintu bizoroha cyane gukora amakosa, tugomba guhora dushya, tuzakira ibisubizo bitunguranye.
Ikigaragara kigaragara ni indangagaciro yingenzi ya hydroxypropyl methyl selulose. Uburyo busanzwe bwo gupima ni ugupima ibizunguruka byuzuzanya, gupima capillary viscosity gupima no gupima ububobere bwo kugwa.
Mbere, hydroxypropyl methyl selulose yagenwe no gupima capillary viscosity gupima, ukoresheje viscometer ya Uhnscher. Igisubizo cyo gupima mubisanzwe ni igisubizo cyamazi ya 2, kandi formula ni: V = Kdt. V ni viscosity mumasegonda, K nigihe gihoraho cya viscometer, D nubucucike bwubushyuhe buhoraho, na T nigihe bifata kugirango uve hejuru ujya hepfo ya viscometero mumasegonda. Ubu buryo bwo gukora buragoye, niba hari ibikoresho bidashonga, biroroshye gutera amakosa, biragoye kumenya ubwiza bwa hydroxypropyl methylcellulose.
Ikibazo cyo kubaka stratifike nikibazo kinini abakiriya bahura nacyo. Mbere ya byose, ikibazo cyibikoresho fatizo bigomba gusuzumwa kugirango hubakwe kole. Impamvu nyamukuru yo kubaka ibice bya kole ni ukudahuza inzoga za polyvinyl (PVA) na hydroxypropyl methylcellulose (HPMC). Impamvu ya kabiri nuko igihe cyo kuvanga kidahagije; Hariho kandi inyubako ya kole yububiko ntabwo ari nziza.
Mu kubaka kole, hydroxypropyl methylcellulose (HPMC) igomba gukoreshwa kuko HPMC ikwirakwizwa mumazi gusa kandi ntishonga. Hafi yiminota 2, ubwiza bwamazi bwiyongera buhoro buhoro, bikora colloid ibonerana.
Ibicuruzwa bishushe bishyushye, mumazi akonje, birashobora gukwirakwira vuba mumazi ashyushye, bikabura mumazi ashyushye, mugihe ubushyuhe bugabanutse kubushyuhe runaka, ubukonje bugaragara buhoro buhoro, kugeza igihe habaye colloid ibonerana. Hydroxypropyl methylcellulose (HPMC) mumyubakire ya kole yinyongera irasabwa kuri 2-4kg.
Hydroxypropyl methyl selulose (HPMC) mu nyubako ya kole ya chimique itajegajega, mildew, ingaruka zo gufata amazi ni nziza, kandi ntabwo ihindurwa nihinduka rya PH, irashobora gukoreshwa kuva 100 000 S - 200 000 S. Ariko mu musaruro ntabwo urwego rwo hejuru rwijimye ni rwiza, ubukonje nimbaraga zumubano biringaniye, niko hejuru cyane, imbaraga ni nto, muri rusange 100.000S viscosity irakwiriye.
