Uburyo bwo Kwipimisha Ibiryo Byiciro bya Sodium CMC Viscosity
Kugerageza ubwiza bwibiryo byo mu rwego rwa sodium carboxymethyl selulose (CMC) ningirakamaro kugirango harebwe imikorere n'imikorere mubikorwa bitandukanye byokurya. Ibipimo bya Viscosity bifasha ababikora kumenya kubyimbye no gutezimbere ubushobozi bwa CMC ibisubizo, nibyingenzi kugirango ugere kubicuruzwa byifuzwa nkibintu, umunwa, hamwe no gutuza. Dore inzira yuzuye yuburyo bwo gupima ibiryo byo mu rwego rwa sodium ya CMC:
1. Ihame:
- Viscosity ni igipimo cyo kurwanya amazi. Kubireba CMC ibisubizo, viscosity iterwa nibintu nko kwibanda kuri polymer, urugero rwo gusimbuza (DS), uburemere bwa molekile, pH, ubushyuhe, nigipimo cyogosha.
- Ubukonje bwibisubizo bya CMC mubusanzwe bipimwa hifashishijwe viscometer, ikoresha impagarara zogutemba kumazi kandi igapima ihinduka ryimiterere cyangwa umuvuduko.
2. Ibikoresho na reagent:
- Urugero rwibiryo bya sodium carboxymethyl selulose (CMC) icyitegererezo.
- Amazi yamenetse.
- Viscometero (urugero, Visfield ya Brookfield, kuzunguruka cyangwa capillary viscometer).
- Spindle ikwiranye nuburinganire bwurugero rwicyitegererezo.
- Ubwogero bwamazi bugenzurwa nubushyuhe cyangwa icyumba cya thermostatike.
- Stirrer cyangwa magnetic stirrer.
- Inzoga cyangwa ibikombe by'icyitegererezo.
- Isaha yo guhagarara cyangwa igihe.
3. Inzira:
- Icyitegererezo:
- Tegura urukurikirane rwibisubizo bya CMC hamwe nibitekerezo bitandukanye (urugero, 0.5%, 1%, 2%, 3%) mumazi yatoboye. Koresha umunzani kugirango upime ingano ikwiye ya poro ya CMC hanyuma uyongereho buhoro buhoro mumazi hamwe no gukurura kugirango umenye neza.
- Emera ibisubizo bya CMC kugirango bihindurwe kandi bingane mugihe gihagije (urugero, amasaha 24) kugirango habeho hydrated hamwe na stabilite.
- Gushiraho ibikoresho:
- Hindura viscometer ukurikije amabwiriza yabakozwe ukoresheje ibisanzwe byamazi ya viscosity.
- Shyira viscometer kumuvuduko ukwiye cyangwa igipimo cyogukurikirana kugirango uteganijwe kwizerwa ryibisubizo bya CMC.
- Shyushya viscometer hanyuma uzenguruke ubushyuhe bwifuzwa ukoresheje ubwogero bwamazi bugenzurwa nubushyuhe cyangwa icyumba cya thermostatike.
- Igipimo:
- Uzuza igikombe cyicyitegererezo cyangwa inzoga hamwe nigisubizo cya CMC kugirango ugerageze, urebe ko spindle yibizwa muri sample.
- Hisha umuzenguruko muri sample, witondere kwirinda kwinjiza umwuka mubi.
- Tangira viscometer hanyuma wemerere kuzunguruka ku muvuduko wagenwe cyangwa igipimo cyogosha mugihe cyagenwe (urugero, umunota 1) kugirango ugere kumiterere-ihagaze.
- Andika ibisomwa bisomeka byerekanwe kuri viscometer. Subiramo ibipimo kuri buri gisubizo cya CMC no kubiciro bitandukanye byogosha nibiba ngombwa.
- Isesengura ryamakuru:
- Tegura indangagaciro zo kurwanya ubukana bwa CMC cyangwa igipimo cyo gukata kugirango ubyare umurongo.
- Kubara indangagaciro zigaragara ku gipimo cyihariye cyo gukata cyangwa kwibanda ku kugereranya no gusesengura.
- Menya imyitwarire ya rheologiya yibisubizo bya CMC (urugero, Newtonian, pseudoplastique, thixotropic) ukurikije imiterere yumurongo wijimye hamwe ningaruka zogukata kwijimye.
- Ibisobanuro:
- Indangagaciro zo hejuru cyane zerekana imbaraga nyinshi zo gutemba no gukomera kwimbaraga za CMC igisubizo.
- Imyitwarire yubukonje bwibisubizo bya CMC irashobora gutandukana bitewe nibintu nko kwibanda, ubushyuhe, pH, nigipimo cyogosha. Gusobanukirwa nibi bintu ni ngombwa mugutezimbere imikorere ya CMC mubikorwa byihariye byibiribwa.
4. Ibitekerezo:
- Menya neza kalibrasi ikwiye no kubungabunga viscometero kugirango ibipime neza kandi byizewe.
- Kugenzura imiterere yikizamini (urugero, ubushyuhe, igipimo cyogosha) kugirango ugabanye guhinduka no kwemeza kubyara ibisubizo.
- Emeza uburyo ukoresheje ibipimo ngenderwaho cyangwa isesengura rigereranya nubundi buryo bwemewe.
- Kora ibipimo bya viscosity kumpande nyinshi mugihe cyo gutunganya cyangwa kubika kugirango usuzume ituze kandi ikwiranye nibisabwa.
Ukurikije ubu buryo bwo kwipimisha, ubwiza bwibisubizo byibiryo byo mu rwego rwa sodium carboxymethyl selulose (CMC) birashobora kugenwa neza, bigatanga amakuru yingirakamaro mugushinga, kugenzura ubuziranenge, no kunoza imikorere mubikorwa byinganda.
