Sodium Carboxymethyl selile ni iki?

Carboxymethylcellulose (CMC) nuruvange rwimiti myinshi kandi ikoreshwa cyane rusanga ikoreshwa mubikorwa bitandukanye kubera imiterere yihariye. Iyi polymer ikomoka kuri selile, polymer karemano iboneka murukuta rw'utugingo ngengabuzima. Carboxymethylcellulose ikomatanyirizwa hamwe no guhindura imiti ya selile binyuze mu kwinjiza amatsinda ya carboxymethyl, ibyo bikaba byongera imbaraga zo gukemura amazi no kubyimba.

Imiterere ya molekulari na Synthesis

Carboxymethylcellulose igizwe n'iminyururu ya selile hamwe na carboxymethyl matsinda (-CH2-COOH) ifatanye na amwe mumatsinda ya hydroxyl kumitwe ya glucose. Synthesis ya CMC ikubiyemo reaction ya selile hamwe na aside ya chloroacetike, bikavamo gusimbuza atome ya hydrogène kumurongo wa selile hamwe na carboxymethyl. Urwego rwo gusimbuza (DS), rwerekana impuzandengo yimibare ya carboxymethyl kumatsinda ya glucose, bigira ingaruka kumiterere ya CMC.

Ibintu bifatika na shimi

1. Gukemura: Kimwe mu bintu bigaragara biranga CMC ni ugukemura amazi, bigatuma igira akamaro kanini mu gukemura amazi. Urwego rwo gusimbuza rugira ingaruka kumashanyarazi, hamwe na DS yo hejuru iganisha kumazi menshi.
2. Viscosity: Carboxymethylcellulose ihabwa agaciro kubushobozi bwayo bwo kongera ububobere bwamazi. Ibi bituma iba ibintu bisanzwe mubicuruzwa bitandukanye, nk'ibiribwa, imiti, n'ibicuruzwa byita ku muntu.
3. Ibyiza byo gukora firime: CMC irashobora gukora firime mugihe cyumye, ikagira uruhare mubikorwa byayo mu nganda aho bisabwa gutwikirwa neza.
4. Ion Guhana: CMC ifite imitungo yo guhana ion, ikemerera gukorana na ion mugisubizo. Uyu mutungo ukunze gukoreshwa mu nganda nko gucukura peteroli no gutunganya amazi mabi.
5. Igihagararo: CMC itajegajega mugihe kinini cyimiterere ya pH, wongeyeho muburyo bwinshi mubikorwa bitandukanye.

Porogaramu

Inganda zikora ibiribwa:

• Umukozi wibyimbye: CMC ikoreshwa nkibintu byiyongera mubicuruzwa bitandukanye byibiribwa, birimo isosi, imyambarire, n’ibikomoka ku mata.
• Stabilisateur: Ihindura emulisiyo mubicuruzwa byibiribwa, ikumira gutandukana.
• Guhindura imyenda: CMC yongerera ubwiza hamwe numunwa wibiribwa bimwe.

2. Imiti:

• Binder: CMC ikoreshwa nka binder mu miti ya farumasi, ifasha guhuriza hamwe ibikoresho.
• Umukozi wo guhagarika: Ikoreshwa mumiti yamazi kugirango irinde gutuza ibice.

3. Ibicuruzwa byawe bwite:

• Guhindura Viscosity: CMC yongewe kumavuta yo kwisiga, shampo, n'amavuta yo kwisiga kugirango bahindure ubwiza bwabo no kunoza imiterere.
• Stabilizer: Ihindura emulisiyo muburyo bwo kwisiga.

4. Inganda zimpapuro:

• Umwanya wo Kuringaniza Ububiko: CMC ikoreshwa mubikorwa byimpapuro kugirango itezimbere imiterere yimpapuro, nkuburyo bworoshye no gucapwa.

5. Inganda z’imyenda:

• Sizing Agent: CMC ikoreshwa kuri fibre kugirango itezimbere imiterere yabo yo kuboha no kongera imbaraga kumyenda yavuyemo.

6. Gucukura amavuta:

• Umukozi Ushinzwe Kugabanya Amazi: CMC ikoreshwa mugucukura amazi kugirango igabanye igihombo cyamazi, bigabanya ibyago byo guhungabana neza.

7. Gutunganya amazi mabi:

• Flocculant: CMC ikora nka flocculant yo gukusanya uduce duto duto, ikaborohereza kuyikuraho mugikorwa cyo gutunganya amazi mabi.

Ibidukikije

Carboxymethylcellulose isanzwe ifatwa nkumutekano kugirango ikoreshwe mubikorwa bitandukanye. Nkibikomoka kuri selile, birashobora kwangirika, kandi ingaruka zidukikije ni nke. Nyamara, ni ngombwa gusuzuma muri rusange ibidukikije bikomoka ku musaruro n’imikoreshereze.

Umwanzuro

Carboxymethylcellulose ni polymer itandukanye kandi ifite agaciro hamwe nibikorwa byinshi mubikorwa bitandukanye. Ihuza ryihariye ryimiterere, harimo gukemura amazi, ubushobozi bwo kubyimba, hamwe no gutuza, bituma iba ikintu cyingenzi mubicuruzwa bitandukanye. Mugihe inganda zikomeje gushakisha ibisubizo birambye kandi byiza, uruhare rwa carboxymethylcellulose rushobora guhinduka, kandi ubushakashatsi burimo burashobora kuvumbura porogaramu nshya kuri iyi polymer idasanzwe.
