Sodium Carboxymethyl selulose yumutungo hamwe ningaruka ziterwa na CMC Viscosity
Sodium Carboxymethyl selulose (CMC) ni polymer ikunze gukoreshwa mubikorwa bitandukanye byinganda, harimo ibiryo, imiti, imiti yita kumuntu, hamwe nogukoresha ibikoresho. Nibikomoka kumazi biva muri selile ikorwa nigikorwa cya selile hamwe na acide chloroacetic na hydroxide ya sodium. CMC irahuzagurika cyane kandi ifite imitungo myinshi ituma ibera porogaramu zitandukanye. Muri iki kiganiro, tuzaganira ku miterere ya CMC nibintu bigira ingaruka nziza.
Ibyiza bya CMC:
- Gukemura: CMC irashonga cyane mumazi, bigatuma byoroshye gufata no gukoresha mubikorwa bitandukanye. Irashobora kandi gushonga mumashanyarazi amwe n'amwe, nka Ethanol na glycerol, bitewe nurwego rwasimbuwe.
- Viscosity: CMC ni polymer igaragara cyane ishobora gukora geles murwego rwo hejuru. Ubukonje bwa CMC buterwa nimpamvu zitandukanye, nkurwego rwo gusimbuza, kwibanda, pH, ubushyuhe, hamwe nubushakashatsi bwa electrolyte.
- Rheologiya: CMC yerekana imyitwarire ya pseudoplastique, bivuze ko ububobere bwayo bugabanuka hamwe no kongera umuvuduko wogosha. Uyu mutungo ni ingirakamaro mubisabwa aho ubukonje bwinshi bukenewe mugihe cyo gutunganya, ariko ubukonje buke burakenewe mugihe cyo gusaba.
- Igihagararo: CMC ihagaze neza murwego runini rwa pH nubushyuhe. Irwanya kandi kwangirika kwa mikorobe, bigatuma ikwiriye gukoreshwa mubiribwa no gukoresha imiti.
- Ibikoresho byo gukora firime: CMC irashobora gukora firime zoroshye, zoroshye iyo zumye. Izi firime zifite inzitizi nziza kandi zirashobora gukoreshwa nkimyenda ikoreshwa muburyo butandukanye.
Ibintu bigira ingaruka kuri CMC:
- Impamyabumenyi yo gusimbuza (DS): Urwego rwo gusimburwa ni impuzandengo yimibare ya carboxymethyl kumatsinda ya anhydroglucose muri molekile ya selile. CMC ifite DS yo hejuru ifite urwego rwo hejuru rwo gusimbuza, biganisha ku kwiyegereza kwinshi. Ni ukubera ko DS yo hejuru iganisha kumatsinda menshi ya carboxymethyl, yongera umubare wa molekile zamazi zihujwe na polymer.
- Kwibanda: Ubukonje bwa CMC bwiyongera hamwe no kwiyongera. Ibi ni ukubera ko murwego rwo hejuru, iminyururu myinshi ya polymer irahari, biganisha kurwego rwo hejuru rwo kwizirika no kwiyongera kwijimye.
- pH: Ubukonje bwa CMC bugira ingaruka kuri pH yumuti. Kuri pH nkeya, CMC ifite ubukonje bwinshi kuko amatsinda ya carboxyl ari mumiterere yabyo kandi arashobora gukorana cyane na molekile zamazi. Kuri pH ndende, CMC ifite ubukonje buke kuko amatsinda ya carboxyl ari mumiterere yabyo kandi ntaho ahuriye na molekile zamazi.
- Ubushyuhe: Ubukonje bwa CMC buragabanuka hamwe n'ubushyuhe bwiyongera. Ni ukubera ko ku bushyuhe bwinshi, iminyururu ya polymer ifite ingufu nyinshi zumuriro, biganisha ku rwego rwo hejuru rwimikorere no kugabanuka kwijimye.
- Kwibanda kuri electrolyte: Ubukonje bwa CMC buterwa no kuba hari electrolytite mugisubizo. Iyo ingufu za electrolyte nyinshi, ubukonje bwa CMC buragabanuka kubera ko ion ziri mu gisubizo zishobora gukorana nitsinda rya carboxyl ya polymer kandi bikagabanya imikoranire yabo na molekile zamazi.
Mu gusoza, Sodium Carboxymethyl selulose (CMC) ni polymer ihindagurika cyane yerekana ibintu byinshi bitandukanye, harimo gukomera, kwiyegeranya, imvugo, gutuza, hamwe no gukora firime. Ubukonje bwa CMC buterwa nimpamvu zitandukanye, nkurwego rwo gusimbuza, kwibanda, pH, ubushyuhe, hamwe nubushakashatsi bwa electrolyte. Gusobanukirwa nibi bintu ni ngombwa mugutezimbere imikorere ya CMC mubikorwa bitandukanye.
