Cellulose end ndi njira yopanga chimodzimodzi

Kupanga kwacellulose earszimaphatikizapo kusintha kwamankhwala kwa cellulose, chifukwa chochokera ku zosemphana ndi zinthu zapadera. Chotsatirachi ndi chidule cha njira zomwe amagwiritsa ntchito kupanga cellose et:

1. Kusankhidwa kwa Cellulose Source:

• Cellulose ede amatha kuchokera ku magwero osiyanasiyana monga mtengo zamkati, mabatire a thonje, kapena zinthu zina zopangidwa ndi mbewu. Kusankha kwa cellulose kumatha kukhudza mikhalidwe ya cellulose ethel ethel ether.

2. Pusi:

• Chuma chomwe chimapangitsa kuti muchepetse ulusi kukhala mawonekedwe okwanira. Kupindika kumatha kupezeka kudzera pamakina, mankhwala, kapena kuphatikiza kwa njira zonse ziwiri.

3. Kuyeretsa:

• Ma cellose opindika amaperekedwa ndikuyeretsa kuti achotse zosayera, lignin, ndi zina zosakhala cellulosic. Kuyeretsa ndikofunikira kuti mupeze zinthu zapamwamba kwambiri.

4. Kukhazikitsa kwa Cellulose:

• Cellulose yoyeretsedwa imayambitsidwa ndi kutupa yankho la alkaline. Izi ndizofunikira popangitsa kuti cellulose ichotsere kwambiri pazomwe zimachitika.

5. Kuzindikira Kutengera:

• Ma cellulose oyambitsidwa omwe amapezeka kukwaniritsidwa, pomwe magulu a eather amadziwitsidwa m'magulu a hydroxyl pa polymer polymer. Ogwiritsa ntchito zodziwika bwino amaphatikizapo Ethylene oxide, ma propyne oxide, sodium chlorocereate, methyl chloride, ndi ena.
• Zomwe zimachitika zimachitika motsogozedwa ndi kutentha kwa kutentha, kukakamizidwa, ndi ph kuti mukwaniritse digiri yazolowa (DS) ndi kupewa mbali zoyipa.

6. Kusambirane ndi kuchapa:

• Pambuyo pa chizindikiritso, malonda nthawi zambiri amakhala osalowererapo kuti achotse ma repunics owonjezera kapena zinthu. Kusamba kwotsatira kumachitika kuti athetse mitundu yotsalira ndi zosayera.

7. Kuyanika:

• Ma cellulose oyeretsedwa komanso opangidwa ndi opangidwa bwino amawuma kuti apeze mankhwala omaliza a ethel ether mu ufa kapena mawonekedwe a granular.

8..

• Njira zosiyanasiyana zowunikira, kuphatikizapo magile a nyukiliya (NMR) SETROSOPY, masinthidwe anayi omwe aperekedwa (FTIR) a STRAPHropy, ndi chromatography, amagwiritsidwa ntchito ngati malo abwino. DS imayang'aniridwa kwambiri kuti muwonetsetse kusintha.

9. Kupanga ndi kugwiritsa ntchito:

• Ma ethel ether amapangidwa m'magulu osiyanasiyana kuti akwaniritse zofunikira zosiyanasiyana. Ma cellulose osiyanasiyana amayenereranso mafakitale osiyanasiyana, monga kapangidwe ka mankhwala, mankhwala, chakudya, zokutira, ndi zina zambiri.

Ndikofunikira kudziwa kuti njira zina ndi zinthu zimasiyana malinga ndi zomwe zimafunidwa ndi ether ether. Opanga nthawi zambiri amagwiritsa ntchito njira zopangira cellulose etrause etrases enieni kuti akwaniritse zosowa za mafakitale osiyanasiyana.
