Kukonzekera kwa cellulose et

Kukonzekera kwacellulose earsZimaphatikizapo kusintha mwachilengedwe polymer cellulose kudzera pakusintha. Izi zimayambitsa magulu a ethers pa magulu a hydroxyl a ma cellulose polymer, zomwe zimapangitsa kuti cellulose ikhale ndi zinthu zapadera. Cellulose yofala kwambiri imaphatikizapo hydroxypropyl methylcellulose (hpmc), carboxymethyl cellulose (thec), ndi ethyl cellose (Enth). Nayi mwachidule njira yokonzekera:

1.

• Njirayi imayamba ndi cellulose, yomwe imachokera ku mitengo yamitengo kapena thonje. Kusankha kwa cellulose kungapangitse katundu wa cellulose ethel ethel ether.

2. Pusi:

• Cellulose imagonjera njira kuti muchepetse ulusiwo kukhala mawonekedwe okwanira kwambiri. Izi zitha kuphatikizira njira zamakina kapena njira zopangira mankhwala.

3. Kuyeretsa:

• Cellulose imayeretsedwa kuchotsa zosayera, lignin, ndi zina zosakhala cellulosic. Gawo loyeretsa ndilofunikira kuti mupeze zinthu zapamwamba kwambiri.

4. Kuzindikira Kutengera:

• Cellulose yoyeretsedwa imapezekanso kwamiyala, pomwe magulu a eathex amadziwitsidwa m'magulu a hydroxyl pa ma cellulose pa cellulose. Kusankha kosangalatsa ndi zomwe zichitike zimatengera kuchuluka kwa ethel ether.
• Ogwiritsa ntchito zodziwika bwino amaphatikizapo Ethylene oxide, ma propyne oxide, sodium chlorocereate, methyl chloride, ndi ena.

5.

• Kutengera kwachinsinsi kumayang'aniridwa mosamala malinga ndi kutentha, kukakamizidwa, ndi ph kuti mukwaniritse digiri yazolowa (DS) ndikupewa zomwe zimachitika.
• Mikhalidwe ya Alkaline nthawi zambiri imagwiritsidwa ntchito, ndipo Ph ya zomwe mungasasankhedwe zimayang'aniridwa kwambiri.

6. Kusambirane ndi kuchapa:

• Pambuyo pa chizindikiritso, malonda nthawi zambiri amakhala osalowererapo kuti achotse ma repunics owonjezera kapena zinthu. Gawoli limatsatiridwa ndikusamba mokwanira kuti muchepetse mitundu 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 zingapo zowunikira zimagwiritsidwa ntchito poyendetsa bwino, kuphatikizapo magile a nyukiliya (NMR) Spectroscopy, masinthidwe anayi omwe aperekedwa (FTIR) wowoneka bwino (FTIR) SEPTOROPY, ndi chromatographycopy, ndi chramotography.
• Mlingo wa zolowa m'malo (DS) ndi gawo lovuta lomwe limayang'aniridwa pakupanga kusinthasintha.

9. Kupanga ndi kunyamula:

• Ma ethel ether amapangidwa m'magulu osiyanasiyana kuti akwaniritse zofunikira zosiyanasiyana. Zogulitsa zomaliza zimayikidwa kuti zigawidwe.

Kukonzekera kwa celluse eders ndi njira yovuta ya mankhwala yomwe imafunikira kuwongolera zinthu mosamala kuti mukwaniritse zomwe mukufuna. Kusintha kwa cellose edelose kumalola kugwiritsa ntchito ntchito zosiyanasiyana pamakampani, kuphatikizapo zamankhwala, kuphatikiza, chakudya, zomanga, zoyamika, zowonjezera.
