Mbere ya byose, igipimo cyubwubatsi bugomba kuzirikana ibikoresho fatizo. Impamvu nyamukuru yo gushyiramo kole yubaka ni ukudahuza hagati ya emulion ya acrylic na hydroxypropyl methylcellulose (HPMC). Icya kabiri, kubera igihe cyo kuvanga kidahagije; hari nubushuhe bubi bwimikorere yubwubatsi. Muri kole yubwubatsi, ugomba gukoresha hydroxypropyl selulose ako kanya (HPMC), kuko HPMC ikwirakwizwa mumazi gusa, ntabwo ishonga. Nyuma yiminota igera kuri 2, ubwiza bwamazi bwiyongereye buhoro buhoro, butanga igisubizo kiboneye cyuzuye viscous colloidal. Ibicuruzwa bishyushye, iyo bihuye namazi akonje, birashobora gukwirakwira vuba mumazi abira bikabura mumazi abira. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ubukonje bugaragara buhoro buhoro kugeza igisubizo kiboneye cyuzuye viscous colloidal. Igipimo cyiza cyane cya hydroxypropyl methylcellulose (HPMC) muri kole yubwubatsi ni 2-4KG.
Hydroxypropyl methylcellulose (HPMC) ifite imiterere yumubiri ihamye mubikoresho byubaka, kandi ifite ingaruka nziza cyane yo gukuraho ibibyimba byoroshye no gufunga amazi, kandi ntibizaterwa nimpinduka zagaciro ka pH. Ubukonje burashobora gukoreshwa hagati ya 100.000 na 200.000 s. Mu nganda, hejuru yubusa, nibyiza. Viscosity iringaniza muburyo bwo guhuza imbaraga. Iyo hejuru ya viscosity, niko imbaraga zo kwikuramo zigabanuka. Mubisanzwe, ubwiza bwa 100.000 s burakwiriye.
Kuvanga CMC namazi hanyuma ukore paste yicyondo kugirango ukoreshwe nyuma. Mugihe ushyiraho paste ya CMC, ongeramo umubare wamazi akonje mukigega cyogeramo hamwe na mashini ikangura. Iyo imashini ikangura itangiye, gahoro gahoro kandi uringaniza selile ya carboxymethyl selile mu kigega cyo kogeramo, hanyuma ukomeze kubyutsa, kugirango carboxymethyl selulose n'amazi bihuze rwose, kandi selile ya carboxymethyl irashonga rwose. Iyo iseswa rya CMC, akenshi biba ngombwa gutatanya kuringaniza no kuvanga ubudahwema, kugirango turusheho "gukumira no guhuriza hamwe kwa CMC nyuma yo guhura n’amazi, no kugabanya ikibazo cy’iseswa rya CMC" no kongera umuvuduko w’iseswa rya CMC .
Igihe cyo kuvanga ntabwo ari kimwe nigihe cya CMC cyo gushonga burundu. ni ibisobanuro 2. Muri rusange, igihe cyo kuvanga ni kigufi cyane kuruta igihe CMC isenyuka burundu, biterwa nibisobanuro. Ishingiro ryo gusuzuma igihe cyo kuvanga ni uko iyo CMC itatanye kimwe mumazi idafite ibibyimba bigaragara, kuvanga birashobora guhagarara, kugirango CMC namazi byinjire hagati yabyo mubihe byimiterere yamakuru. Hariho impamvu nyinshi zo kumenya igihe gikenewe cyo gusesa burundu CMC:
(1) CMC n'amazi byahujwe rwose, kandi nta bikoresho bikomeye byo gutandukanya amazi-hagati;
(2) Ivangavanze rivanze neza kandi risanzwe, hamwe n'ubuso bworoshye kandi bworoshye;
. Bifata amasaha 10 kugeza kuri 20 uhereye igihe CMC ishyizwe mubigega byo kuvanga hanyuma ikavangwa n'amazi kugeza igihe bishiriye burundu.
