Sodium carboxymethylcellulose. Igikorwa cyo gukora SCMC gikubiyemo intambwe nyinshi, zirimo alkalisation, etherification, kweza, no gukama.

1. Alkalisation

Intambwe yambere mubikorwa byo gukora SCMC ni alkalisation ya selile. Cellulose ikomoka ku biti by'ibiti cyangwa ipamba, bigabanyijemo uduce duto binyuze mu buryo bwo kuvura imashini. Cellulose yavuyemo noneho ivurwa na alkali, nka sodium hydroxide (NaOH) cyangwa potasiyumu hydroxide (KOH), kugirango yongere imbaraga kandi ikemuke.

Igikorwa cya alkalisation gikubiyemo kuvanga selile hamwe nigisubizo cyibanze cya NaOH cyangwa KOH mubushyuhe bwinshi hamwe nigitutu. Imyitwarire hagati ya selile na alkali itera gukora sodium cyangwa potasiyumu selulose, ikora cyane kandi irashobora guhinduka byoroshye.

2. Etherification

Intambwe ikurikira mubikorwa byo gukora SCMC ni etherification ya sodium cyangwa potasiyumu selulose. Ubu buryo bukubiyemo kwinjiza amatsinda ya carboxymethyl (-CH2-COOH) kumugongo wa selile ukoresheje reaction ya acide chloroacetic (ClCH2COOH) cyangwa sodium cyangwa umunyu wa potasiyumu.

Imyitwarire ya etherification isanzwe ikorwa mumazi ya Ethanol ivanze nubushyuhe bwo hejuru hamwe nigitutu, hiyongereyeho catalizator, nka sodium hydroxide cyangwa sodium methylate. Imyitwarire irakabije kandi isaba kugenzura neza imiterere yimyitwarire kugirango wirinde ubushyuhe bukabije no kwangirika kwibicuruzwa.

Urwego rwa etherification, cyangwa umubare wamatsinda ya carboxymethyl kuri molekile ya selile, irashobora kugenzurwa muguhindura imiterere yimyitwarire, nko kwibumbira hamwe kwa acide chloroacetike nigihe cyo kubyitwaramo. Impamyabumenyi yo hejuru ya etherification itera amazi menshi hamwe nubukonje bwinshi bwa SCMC yavuyemo.

3. Kwezwa

Nyuma ya reaction ya etherification, SCMC yavuyemo mubisanzwe yandujwe numwanda, nka selile idakozwe, alkali, na acide chloroacetic. Intambwe yo kweza ikubiyemo gukuraho ibyo byanduye kugirango ubone ibicuruzwa byiza kandi byiza-byiza bya SCMC.

Igikorwa cyo kweza gikubiyemo intambwe nyinshi zo gukaraba no kuyungurura ukoresheje amazi cyangwa ibisubizo byamazi bya Ethanol cyangwa methanol. SCMC yavuyemo noneho itabangikanywa na aside, nka aside hydrochloric cyangwa acide acike, kugirango ikureho alkali isigaye kandi ihindure pH kurwego rwifuzwa.

4. Kuma

Intambwe yanyuma mubikorwa byo gukora SCMC ni ukumisha ibicuruzwa bisukuye. SCMC yumye mubisanzwe muburyo bwa poro yera cyangwa granule kandi birashobora gutunganywa muburyo butandukanye, nkibisubizo, geles, cyangwa firime.

Uburyo bwo kumisha burashobora gukorwa hakoreshejwe uburyo butandukanye, nko kumisha spray, gukama ingoma, cyangwa kumisha vacuum, bitewe nibicuruzwa byifuzwa hamwe nubunini bwibicuruzwa. Uburyo bwo kumisha bugomba kugenzurwa neza kugirango wirinde ubushyuhe bukabije, bushobora kuviramo kwangirika cyangwa guhindura ibara.

Porogaramu ya Sodium Carboxymethylcellulose

Sodium carboxymethylcellulose (SCMC) ikoreshwa cyane mu nganda zitandukanye, nk'ibiribwa, imiti, imiti yo kwisiga, no kwita ku muntu ku giti cye, kubera amazi meza cyane, kubyimba, gutuza, no kumera neza.

Inganda zikora ibiribwa

Mu nganda z’ibiribwa, SCMC isanzwe ikoreshwa nkibyimbye, stabilisateur, na emulisiferi mubicuruzwa byinshi byibiribwa, nkibicuruzwa bitetse, ibikomoka ku mata, amasosi, imyambarire, n'ibinyobwa. SCMC ikoreshwa kandi mugusimbuza ibinure mubiribwa birimo amavuta make kandi bigabanuka-karori.
