Inganda zikora nibiranga Sodium Carboxymethyl Cellulose

Sodium carboxymethyl selulose (Na-CMC) ni polymer ikemura amazi ikomoka kuri selile, ikoreshwa cyane mubikorwa bitandukanye byinganda nkibiryo, imiti, amavuta yo kwisiga, imyenda, no gucukura amavuta.Azwiho kubyimbye kwiza, gutuza, no guhuza ibintu.Muri iki kiganiro, tuzaganira kubikorwa byo gukora nibiranga sodium carboxymethyl selulose.

Uburyo bwo gukora Sodium Carboxymethyl Cellulose

Umusaruro wa Na-CMC urimo intambwe nyinshi, harimo gukuramo selile mu mbaho, ibiti by'ipamba, cyangwa andi masoko, hanyuma hakurikiraho guhindura selile kugirango habeho amatsinda ya carboxymethyl.Ibikorwa byo gukora Na-CMC birashobora kuvunagurwa muburyo bukurikira:

1. Gukuramo Cellulose: Cellulose ikurwa mu mbaho ​​cyangwa mu zindi nkomoko binyuze mu buryo bwo kuvura imashini na chimique, harimo guhumeka, guhumeka, no gutunganya.
2. Umuti wa Alkali: Cellulose yakuweho ivurwa n'umuti ukomeye wa alkaline, ubusanzwe hydroxide ya sodium (NaOH), kugirango ubyimba fibre selile kandi ugaragaze amatsinda ya hydroxyl.
3. Etherification: Fibre ya selile yabyimbye noneho ikorwa hamwe na sodium monochloroacetate (SMCA) imbere ya catalizike ya alkaline nka sodium karubone (Na2CO3) kugirango itangire amatsinda ya carboxymethyl kumugongo wa selile.
4. Kutabogama: Carboxymethylated selulose noneho itabangamiwe na aside nka hydrochloric aside (HCl) cyangwa aside sulfurike (H2SO4) kugirango ikore Na-CMC.
5. Kweza no Kuma: Na-CMC isukurwa no gukaraba no kuyungurura kugirango ikureho umwanda wose hanyuma ikumishwa kugirango ibone ifu itemba yubusa.

Ibiranga Sodium Carboxymethyl Cellulose

Imiterere ya Na-CMC irashobora gutandukana bitewe nurwego rwo gusimbuza (DS), bivuga umubare wamatsinda ya carboxymethyl kumurwi wa anhydroglucose (AGU) wa selile.Bimwe mubyingenzi biranga Na-CMC ni:

1. Gukemuka: Na-CMC irashobora gushonga cyane kandi irashobora gukora ibisubizo bisobanutse neza.
2. Viscosity: Ubukonje bwibisubizo bya Na-CMC biterwa nubunini, DS, nuburemere bwa molekuline ya polymer.Na-CMC izwiho kuba ifite umubyimba mwiza kandi irashobora gukoreshwa kugirango wongere ubwiza bwibisubizo nibihagarikwa.
3. pH Ihamye: Na-CMC ihagaze neza kumurongo mugari wa pH, kuva acide kugeza alkaline, bigatuma ikoreshwa muburyo butandukanye.
4. Kwihanganira umunyu: Na-CMC yihanganira cyane umunyu kandi irashobora kugumana ubukonje bwayo no guhagarara neza imbere ya electrolytite.
5. Ubushyuhe bwumuriro: Na-CMC ihagaze neza mubushyuhe bwinshi kandi irashobora gukoreshwa mubikorwa bitandukanye byinganda bisaba ubushyuhe bwo hejuru.
6. Ibinyabuzima bishobora kwangirika: Na-CMC irashobora kwangirika kandi irashobora gutabwa neza mubidukikije.

Umwanzuro

Sodium carboxymethyl selulose ni polymer itandukanye ikoreshwa cyane mubikorwa bitandukanye byinganda bitewe nubunini bwayo buhebuje, butajegajega, kandi buhuza.Igikorwa cyo gukora Na-CMC gikubiyemo gukuramo selile ikurikirwa no guhindura selile kugirango habeho amatsinda ya carboxymethyl.Na-CMC ifite ibintu byinshi biranga nko kwikemurira ibibazo, ubukonje, pH itajegajega, kwihanganira umunyu, ituze ryumuriro, hamwe na biodegradabilite, bigatuma ikoreshwa muburyo butandukanye.Imiterere ya Na-CMC irashobora guhindurwa mugucunga urwego rwo gusimbuza, uburemere bwa molekile, hamwe no kwibanda, bigatuma igikoresho cyingirakamaro mubikorwa bitandukanye byinganda.
