Carboxymethyl selulose (CMC) ni polymer itandukanye ikoreshwa cyane mu nganda zitandukanye nk'ibiribwa, imiti, amavuta yo kwisiga, n'imyenda. Azwiho ubushobozi bwo gukora nkumubyimba, stabilisateur, binder, hamwe nogukoresha amazi. Iyo ivanze neza namazi, CMC ikora igisubizo kiboneka gifite imiterere yihariye ya rheologiya.
Gusobanukirwa CMC:
Imiterere yimiti nimiterere ya CMC.
Gukoresha inganda n'akamaro mubice bitandukanye.
Akamaro ko kuvanga neza kugirango ugere kubikorwa wifuza.
Guhitamo icyiciro cya CMC:
Ibyiciro bitandukanye bya CMC biboneka hashingiwe ku bwiza, urwego rwo gusimburwa, no kwera.
Guhitamo amanota akwiranye ukurikije ibyateganijwe hamwe nibiranga igisubizo.
Ibitekerezo byo guhuza nibindi bikoresho muburyo bwo gutegura.
Ibikoresho n'ibikoresho:
Ibikoresho bisukuye kandi bifite isuku yo kuvanga.
Ibikoresho bikurura nka mashini ya mashini, ivanga, cyangwa inkoni ikurura.
Impamyabumenyi ya silinderi cyangwa ibikombe byo gupima kugirango bipime neza CMC namazi.
Ubuhanga bwo kuvanga:
a. Kuvanga ubukonje:
Ongeramo CMC gahoro gahoro mumazi akonje hamwe no guhora ukurura kugirango wirinde gukomera.
Buhoro buhoro kongera umuvuduko wo kwihuta kugirango tumenye gutandukana.
Emerera umwanya uhagije wo kuyobora no gusesa ibice bya CMC.
b. Kuvanga Bishyushye:
Gushyushya amazi kubushyuhe bukwiye (mubisanzwe hagati ya 50-80 ° C) mbere yo kongeramo CMC.
Buhoro buhoro usuka CMC mumazi ashyushye mugihe ukomeza.
Kugumana ubushyuhe murwego rusabwa kugirango byoroherezwe kwihuta no gukwirakwiza CMC.
c. Kuvanga cyane-Shear:
Gukoresha imashini yihuta yivanga cyangwa homogenizers kugirango ugere neza neza kandi byihuse.
Kugenzura neza uburyo bwo kuvanga imiterere kugirango wirinde ubushyuhe bukabije.
Gukurikirana ibishishwa no guhindura ibipimo bivanga nkuko bikenewe kugirango ugere kubyo wifuza.
d. Kuvanga Ultrasonic:
Gukoresha ibikoresho bya ultrasonic kugirango ukore cavitation na micro-turbulance mugisubizo, byorohereza ikwirakwizwa ryihuse rya CMC.
Kunonosora inshuro nyinshi nimbaraga zishingiye kubisabwa byihariye.
Gukoresha ultrasonic kuvanga nkubuhanga bwinyongera kugirango wongere gutatanya no kugabanya igihe cyo kuvanga.
Ibitekerezo byubuziranenge bwamazi:
Gukoresha amazi asukuye cyangwa yatoboye kugirango ugabanye umwanda nibihumanya bishobora kugira ingaruka kumikorere ya CMC.
Gukurikirana ubushyuhe bwamazi na pH kugirango hamenyekane neza na CMC no kwirinda ingaruka mbi cyangwa kwangirika.
Kuvomera no gusesa:
Gusobanukirwa hydrated kinetics ya CMC no kwemerera umwanya uhagije wo kuyobora neza.
Gukurikirana ihinduka ryijimye mugihe cyo gusuzuma aho iseswa rigeze.
Guhindura kuvanga ibipimo cyangwa kongeramo amazi nkuko bikenewe kugirango ugere kubwiza bwifuzwa kandi buhoraho.
Kugenzura Ubuziranenge no Kwipimisha:
Gukora ibipimo bya viscosity ukoresheje viscometero cyangwa rheometero kugirango umenye ubuziranenge bwigisubizo cya CMC.
Gukora ingano yubunini bwisesengura kugirango hamenyekane gutandukana no kubura agglomerates.
Gukora ibizamini bihamye kugirango usuzume ubuzima-bwimikorere nigikorwa cya CMC igisubizo muburyo butandukanye.
Gushyira mu bikorwa ivangwa rya CMC-Amazi:
Inganda zikora ibiryo: Kuzunguruka no gutuza isosi, imyambarire, nibikomoka ku mata.
Inganda zimiti: Gutegura guhagarikwa, emulisiyo, nibisubizo byamaso.
Inganda zo kwisiga: Kwinjiza amavuta, amavuta yo kwisiga, hamwe nibicuruzwa byita kumuntu kugirango bigabanye ubukana no guhagarika emulsiyo.
Inganda zimyenda: Kongera ububobere bwo gucapa paste no kugereranya.
Kuvanga CMC mumazi ninzira yingenzi isaba gutekereza neza kubintu bitandukanye nko gutoranya amanota, kuvanga tekinike, ubwiza bwamazi, hamwe ningamba zo kugenzura ubuziranenge. Mugukurikiza umurongo ngenderwaho uvugwa muriki gitabo cyuzuye, ababikora barashobora kwemeza ko ikwirakwizwa ryiza kandi ryiza rya CMC, biganisha ku gushiraho ibisubizo byujuje ubuziranenge hamwe nibikorwa bihoraho mubikorwa bitandukanye.
