Carboxymethylcellulose (CMC) na methylcellulose (MC) byombi ni ibintu bikomoka kuri cellulose, polymer karemano iboneka mu nkuta z'uturemangingo tw'ibimera. Ibi bikomoka kuri cellulose bikoreshwa cyane mu nganda zitandukanye bitewe n'imiterere yabyo yihariye. Nubwo bisa, CMC na MC bifite itandukaniro ritandukanye mu miterere yabyo ya shimi, imiterere yabyo, ikoreshwa ryabyo, n'ikoreshwa ryabyo mu nganda.
1. Imiterere ya chimique:
Karuboksimetiliseliselulosi (CMC):
CMC ikorwa binyuze mu guhindurwa kwa selulose hamwe na aside chloroacetic, bigatuma amatsinda ya hydroxyl (-OH) asimburwa ku ruti rw'umugongo rwa selulose n'amatsinda ya carboxymethyl (-CH2COOH).
Igipimo cyo gusimbuza (DS) muri CMC kivuga ku mubare mpuzandengo w'amatsinda ya karuboksimetili kuri buri gice cya glucose mu ruhererekane rwa selulosi. Iki gipimo kigena imiterere ya CMC, harimo gushonga, ubushyuhe, n'imyitwarire ya rheological.
Methylcellulose (MC):
MC ikorwa binyuze mu gusimbuza amatsinda ya hydroxyl muri selulose n'amatsinda ya methyl (-CH3) binyuze mu guhindurwa kwa ether.
Kimwe na CMC, imiterere ya MC iterwa n'urwego rwo gusimbuza, ibyo bikaba bigena ingano ya methylation ku ruhererekane rwa cellulose.
2. Gushonga:
Karuboksimetiliseliselulosi (CMC):
CMC irashonga mu mazi kandi ikora ibisubizo bibonerana kandi bitose.
Gushonga kwayo biterwa na pH, kandi gushonga kwayo kwinshi mu bihe bya alkaline.
Methylcellulose (MC):
MC nayo irashonga mu mazi, ariko gushonga kwayo biterwa n'ubushyuhe.
Iyo ishongeshejwe mu mazi akonje, MC ikora gel, ishongeshwa mu buryo busubirwaho iyo ishyushye. Iyi miterere ituma ikoreshwa mu buryo busaba gel igenzurwa.
3. Ubucucike:
CMC:
Igaragaza ubukana bwinshi mu bisubizo by'amazi, bigatuma irushaho gukomera.
Uburemere bwayo bushobora guhindurwa hakoreshejwe ibintu bihindura urugero nk'ubwinshi, urugero rw'ubuhinduzi, na pH.
MC:
Igaragaza imyitwarire yo kumera nk'iya CMC ariko muri rusange ntabwo imera nk'iy'izuba.
Ubushyuhe bw'ibisubizo bya MC bushobora kandi kugenzurwa hakoreshejwe guhindura ibipimo nk'ubushyuhe n'ubwinshi.
4. Gutunganya filime:
CMC:
Ikora filime zisobanutse neza kandi zoroshye iyo ikozwe mu bisubizo byayo by'amazi.
Izi filime zikoreshwa mu nganda nko gupakira ibiribwa no mu miti.
MC:
Nanone irashobora gukora filime ariko ikunda kwangirika cyane ugereranije na filime za CMC.
5. Inganda z'ibiribwa:
CMC:
Ikoreshwa cyane nk'ikintu gikomeza ubushyuhe, gikonjesha, kandi gitera imbaraga mu biryo nka ice cream, isosi, n'ibindi biryo.
Ubushobozi bwayo bwo guhindura imiterere n'uko ibiryo bifata mu kanwa bituma igira akamaro mu miterere y'ibiryo.
MC:
Ikoreshwa mu bikorwa bisa na CMC mu biribwa, cyane cyane mu bikorwa bisaba gukora gel no kuyituza.
6. Imiti:
CMC:
Ikoreshwa mu buryo bw'imiti nk'uburyo bwo guhuza, gutandukanya, no guhindura ubushyuhe mu gukora ibinini.
Nanone ikoreshwa mu miti ikoreshwa mu gusiga amavuta nk'amavuta n'ama-gel bitewe n'ubushobozi bwayo bwo kuvura indwara za rheological.
MC:
Ikoreshwa cyane nk'umuti ugabanya ubukana bw'ibinure mu miti, cyane cyane mu miti ikoreshwa mu kunywa no mu bisubizo by'amaso.
7. Ibikoresho byo kwita ku buzima bw'umuntu ku giti cye:
CMC:
Iboneka mu bikoresho bitandukanye byo kwiyitaho nk'amenyo y'amenyo, shampoo, n'amavuta yo kwisiga nk'ikintu gikomeza ubuziranenge no gukurura ububobere.
MC:
Ikoreshwa mu buryo busa na CMC, igira uruhare mu gutuma imiti yo kwita ku mubiri ihora imeze neza kandi ihamye.
8. Porogaramu zo mu nganda:
CMC:
Yakoreye mu nganda nk'imyenda, impapuro, n'ibumba kubera ubushobozi bwayo bwo gukora nk'icyuma gifunga, gihindura imiterere y'amaraso, ndetse n'igikoresho cyo kubika amazi.
MC:
Ikoreshwa mu bikoresho by'ubwubatsi, amarangi, n'ibindi bikoresho by'ubukorikori bitewe n'ubushobozi bwayo bwo gukomera no gufatanya.
Mu gihe carboxymethylcellulose (CMC) na methylcellulose (MC) byombi ari ibintu bikomoka kuri cellulose bifite uburyo butandukanye bwo gukoreshwa mu nganda, bigaragaza itandukaniro mu miterere yabyo ya shimi, imyitwarire yo gushonga, imiterere y’ubushyuhe, n’uburyo bikoreshwa. Gusobanukirwa iri tandukaniro ni ingenzi mu guhitamo ibikomoka kuri shimi bikwiye gukoreshwa mu nganda zitandukanye, kuva ku biribwa n’imiti kugeza ku kwita ku muntu ku giti cye no mu nganda. Byaba bikenewe ko habaho icyuma gipima pH nka CMC mu bicuruzwa by’ibiribwa cyangwa se icyuma gipima ubushyuhe nka MC mu miti, buri kimwe gikomoka kuri shimi gitanga inyungu zidasanzwe zijyanye n’ibikenewe mu nzego zitandukanye.
