Ukadaulo wa cellulose et

Ukadaulo wacellulose earsZimaphatikizapo kusintha kwa cellulose, polymer yachilengedwe yochokera ku bele lazomera, kuti apange zotumphukira zomwe zili ndi zomwe zimapangidwa ndi zinthu zina. Cellulose yofala kwambiri imaphatikizapo hydroxypropyl methylcellulose (hpmc), carboxymethyl cellulose (thec), ndi ethyl cellose (Enth). Nayi mwachidule za ukadaulo womwe umagwiritsidwa ntchito popanga cellose et:

1. Zopangira:
   • Cellulose gwero: Zinthu zoyambirira zopangira cellulose ndi cellulose, zomwe zimapezeka ku mitengo yamitengo kapena thonje. Kugwetsa kwa cellulose kumakhudza katundu wa cellulose ethel ethel ether.
2. Kukonzekera kwa Cellulose:
   • Kupindika: Pulm Pulp kapena thonje amagonjera njira kuti muchepetse ulusi wa cellulose kukhala mawonekedwe okwanira.
   • Kuyeretsa: Cellulose imayeretsedwa kuti ichotse zodetsa ndipo liglin, zomwe zimapangitsa kuti pakhale cellulose yoyeretsedwa.
3. Kusintha Mankhwala:
   • Kuzindikira Kuchita: Gawo lofunikira mu cellulose eyathese ndi kusintha kwa mankhwala kwa cellulose posinthana. Izi zimaphatikizapo kuyambitsa magulu a etherth (mwachitsanzo, hydroxethyl, hydroxypyll, carboxymethyl, methyl, kapena ethyl magulu a hydroxyl pa polymer polymer polymer.
   • Kusankha Zodzikongoletsera: Kusankha monga Ethylene oxide, ma prowyne oxide, sodium chlorocetate, kapena methyl chloride nthawi zambiri amagwiritsidwa ntchito pazomwezi.
4. Kuwongolera kwa magawo azochitika:
   • Kutentha ndi Kutengera: Kusintha kumachitika kumachitika pansi pa kutentha ndi kukakamizidwa kuti mukwaniritse digiri ya zolowa m'malo mwazolowetsa.
   • Mikhalidwe ya Alkaline: Zochita zambiri zoyesedwa zimachitika pansi pa mikhalidwe ya alkalinine, ndipo pH ya osakaniza imayang'aniridwa mosamala.
5. Kuyeretsa:
   • Kulowerera: Pambuyo pa chizindikiritso, malonda nthawi zambiri amakhala osalowererapo kuti achotse ma flants owonjezera kapena zinthu.
   • Kusamba: Disulose yosinthidwa imatsukidwa kuti ithetse mankhwala ndi zosayera.
6. Kuyanika:
   • Ether cellulose ether imauma kuti ipeze chinthu chomaliza mu ufa kapena mawonekedwe a granular.
7. Kuwongolera kwapadera:
   • Kusanthula: Njira zingapo zowunikira, monga magileorpor magnetic resonance (NMR) SETREOSCOPY, FTIIR)
   • Mlingo wa zolowa m'malo mwake:
8. Kupanga ndi kugwiritsa ntchito:
   • Matenda omaliza: cellulose yokhazikika imaperekedwa kuti azigwiritsa ntchito mafakitale osiyanasiyana, kuphatikizapo kapangidwe ka zomangamanga, mankhwala, chisamaliro, ndi zokutira.
   • Maphunziro a Maphunziro: Magulu osiyanasiyana a cellulose amapangidwa kuti akwaniritse zofunikira zosiyanasiyana.
9. Kafukufuku ndi Zatsopano:
   • Kupititsi patsogolo: Kufufuza ndi chitukuko ndi chitukuko kumangoyang'ana njira zopangira, zimathandizira magwiridwe antchito a cellulose et, ndikuwunika mafinya.

Ndikofunikira kudziwa kuti ukadaulo wopanga cellulose yosiyanasiyana imatha kukhala yosiyanasiyana malinga ndi zomwe mukufuna. Kusintha kowongolera kwa cellulose kudzera pakusinthika kumalola kuti cellulose osiyanasiyana ikhale ndi mphamvu zosiyanasiyana, kuwapangitsa kukhala ofunika m'mafakitale osiyanasiyana.
