Njira Zopanga za Sodium CarboxymethylElose

Njira zopangira sodium carboxymethylmelose (cmc) imaphatikizapo njira zingapo, kuphatikiza kukonza kwa cellulose, kuwunikira, kuyeretsedwa. Nayi chidule cha ntchito yopanga:

1. Kukonzekera kwa Cellulose: Njirayi imayamba ndikukonzekera kwa cellulose, yomwe imakwiririka ku mitengo yamtengo wapatali kapena ya thonje. Cellulose imayeretsedwa koyamba ndikuyefaniza kuchotsa zosayera monga liglin, Himillilose, ndi zodetsa zina. Cellose yoyeretsedwayi imakhala zinthu zoyambira kupanga cmc.
2. Alkilization: Cellulose yoyeretsedwa imathandizidwa ndi yankho la alkaline, nthawi zambiri sodium hydroxide (Naoh), kuti muchepetse chidwi chake. Kuyamwa kumathandizanso kutupa komanso kutsegula ulusi wa cellulose, kuwapangitsa kuti azisinthana ndi mankhwala.
3. Kuzindikira Kutengera: Cellulose yoyatsidwa ya monochlorororoortic acid (MCA) kapena mchere wake wa sodium monochlorocetate (SMCA), pamaso pa chothandizira choyendetsedwa. Kutengera kwachizolowezi kumakhudza kulowetsanso magulu a ma hydroxyl magulu pa cellulose omwe ali ndi carboxymethyl (-ch2coona). Mulingo wazolowa (DS), zomwe zikuyimira chiwerengero cha mabatani a Carboxymethyl pa gawo la shuga wa cellulose, amatha kuwongolera ndi kusintha kwa magawo, nthawi yanthawi yayitali, komanso nthawi yayitali.
4. Kusinthana: Pambuyo pa chizindikiritso, zotsatira zake zimalowerera ndale kuti zisandutse magulu omwe ali ndi ma acidico (carboxymethycellulose sodium). Izi zimatheka powonjezera njira ya alkaline, monga sodium hydroxide (Naoh), ku zomwe mungaganizire. Kusalowerera kumathandizanso kusintha PH ya yankho ndikukhazikitsa CMC.
5. Kuyeretsa: Malo osefukira a rodide sodium amatsukidwa kuti achotse zodetsa, zopangidwa zosasunthika, komanso zopangidwa ndi zosakaniza. Njira zoyeretsera zimatha kuphatikizira kuchapa, kusefedwa, centerribugation, ndi kuyanika. CMC yoyeretsedwa imasambitsidwa ndi madzi kuti muchotse zotsalira ndi ma alkali otsalira, kutsatiridwa ndi kusefera kapena centrifigation kuti muletse zipatso zolimba za cmc kuchokera ku gawo lamadzi.
6. Kuyanika: Chuma choyeretsa cha sodium carboxymethylcelose chimawuma kuti muchotse chinyezi chambiri ndikupeza chinyezi chomwe mukufuna chosungira ndikusinthanso. Njira zowuma zimatha kuphatikizapo kuyanika kwa mpweya, kuyanika, kapena kuyanika, kutengera mawonekedwe ndi mapangidwe omwe akufuna ndi kupanga.

Zotsatira za sodium carboxymethylceloulose zopangidwa ndi ufa woyera kapena zinthu zoyera ndi zotupa za granolar. Amagwiritsidwa ntchito ngati wothandizira, wokhazikika, binder, ndi rheology okhazikika m'mafakitale osiyanasiyana, kuphatikiza, zodzola, ndi mafakitale.
