Ako kanya hydroxypropyl methylcellulose ether yagenewe ibicuruzwa bishingiye kumazi. Ubuso bwa hydroxypropyl methylcellulose ether ivurwa na glyoxal munsi yubushyuhe runaka nagaciro ka pH. Hydroxypropyl methyl selulose ether ivurwa murubu buryo ikwirakwizwa gusa mumazi akonje atagira aho abogamiye nta kubyimba no kwiyegeranya, bigira uruhare mugutinda kubyimba. Muri iki gihe, igisubizo cyamazi kivangwa muminota 5-10 cyangwa mugihe ibidukikije byakemuwe (PH agaciro) byahinduwe kuba alkaline, hydroxypropyl methylcellulose ether itangira kubyimba no kubyara ububobere. Ubu bwoko bwavuwe muburyo busanzwe bwitwa ubwoko bwako kanya.
Ikiranga hydroxypropyl methylcellulose ako kanya nuko iyo ihuye namazi akonje, izahita ikwirakwira mumazi akonje, ariko bifata igihe kugirango ububobere bwayo buzamuke, kuko butandukana mumazi gusa mugihe cyambere, kandi ntibishonga muri a ibisobanuro bifatika. Ubukonje bwabwo bugera ku giciro kinini mu minota 20 cyangwa irenga. Ibyiza byibi nuko ikoreshwa munganda runaka itavanze ifu yumye, cyangwa mugihe ikeneye gushonga kandi amazi ashyushye ntashobora gukoreshwa kubera imiterere yibikoresho nizindi mpamvu. Ako kanya hydroxypropyl methylcellulose ikemura ikibazo nkiki.
Ubwoko bwa hydroxypropyl methylcellulose ihita ikwirakwira vuba mumazi (impamyabumenyi yo gutatanya ni 100%), irashonga vuba, ntisenyuka, cyane cyane mubyiciro byakurikiyeho, igisubizo cya colloidal gifite umucyo mwinshi (kugeza 95%) kandi bihamye, bikemura ibibazo mubikorwa bifatika. Imbogamizi, kwagura umurima wo gusaba, nkibisabwa muri kole yubwubatsi, ikoreshwa mubintu bivangwa n’amazi, hamwe nimirima idasanzwe nko koza imiti ya buri munsi.
Twatangije ibikoresho n’ikoranabuhanga bigezweho ku isi, dufite umurongo wa kijyambere wa selile ya ether na pisitori ya latx isubirwamo, kandi tumenye guha abakoresha ibicuruzwa bishimishije hamwe na sisitemu yo kugenzura ubuziranenge, sisitemu yo gupima na serivisi nziza ku rubuga. Ubu ibicuruzwa biza imbere ni hydroxypropyl methylcellulose HPMC, hydroxyethyl selulose HEC, hydroxypropyl krahisi ether HPS, isubiranamo ryifu ya latx. Ibicuruzwa bikoreshwa cyane mubwubatsi, inganda zikora imiti, amarangi, inganda zimiti ya buri munsi, inganda za gisirikare nizindi nzego, kandi bikozwe muburyo bwo gukora firime, ibifatika, ibitatanya, stabilisateur, kubyimba, nibindi.
Ishingiye ku bwiza bw’ibicuruzwa byayo, uko ihagaze ndetse n’ingaruka zabyo mu nganda zumye zubaka ibikoresho byongera inganda, kandi hashingiwe ku guhora dukomeza inshingano z’ibikorwa by’ubuziranenge mbere, ubu irakorana n’inganda mpuzamahanga ndetse n’imbere mu gihugu zizwi cyane ku bicuruzwa byuzuzanya. Ibikorwa byo gushyigikira: fibre polypropilene, fibre yimbaho, ifu ya krahisi yahinduwe, ifu ya alcool ya polyvinyl, ifu ya defoamer, kugabanya amazi, imiti yica amazi, calcium ikora nibindi byongera ifu yumye.
