Njira yopangira methyl cellulose ether

Kupangamethyl cellulose etherimaphatikizapo kusintha kwa mankhwala kwa cellulose pochita bwino. Methyl cellulose (MC) ndi cellulose yamadzi pa cellur ense ogwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Nayi chidule cha njira yopangira methyl cellulose ether ether:

1. Kusankhidwa kwa Cellulose Source:

• Njirayi imayamba ndikusankhidwa kwa gwero la cellulose, lomwe limachokera ku prglyp kapena thonje. Kupanga kwa Cellulose kumasankhidwa kutengera zomwe mukufuna kudziwa za methyl celluse.

2. Pusi:

• Chuma chosankhidwa cha pa cellulose chimatulutsa, njira yomwe imasokoneza ulusiwo kukhala mawonekedwe okwanira. Kupindika kumatha kupezeka kudzera mu njira zamakina kapena zamagetsi.

3. Kukhazikitsa kwa Cellulose:

• Cellulose yokongoletsa imakhazikitsidwa ndikuchiritsa ndi yankho la alkaline. Gawoli likufuna kutukula bwino kwambiri cellulose, kuwapangitsa kuti ayambe kugwira ntchito mopitirira muyeso.

4. Kuzindikira Kutengera:

• Ma cellulose oyambitsidwa omwe amapezeka kukwaniritsidwa, pomwe magulu a eather, a Methyl, amadziwitsidwa m'magulu a hydroxyl pa ma cellulose pa cellulose.
• Kuchuluka kwa makonda kumakhudza kugwiritsa ntchito mitundu ya methylaing monga sodium hydroxide ndi methyl chloride kapena dimethyl sulfate. Zochitikazo, kuphatikizapo kutentha, kukakamizidwa, ndi nthawi yochita, imayang'aniridwa mosamala kuti mukwaniritse kuchuluka kwa zomwe mukufuna (DS).

5..

• Pambuyo pa chizindikiritso, malondawo samalowererapo kuti achotse kwambiri alkali. Kutsutsidwa kotsatira kumachitika kuti athetse mankhwala ndi zosayera.

6. Kuyanika:

• Ma cellulose ndi a methylated cellose amawuma kuti apeze methyl cellulose ether mu mawonekedwe a ufa kapena granules.

7.

• Njira zosiyanasiyana zowunikira, kuphatikizapo magile a nyukiliya (NMR) SETROSOPY, masinthidwe anayi omwe aperekedwa (FTIR) a STRAPHropy, ndi chromatography, amagwiritsidwa ntchito ngati malo abwino. Mulingo wa zolowa m'malo (DS) ndi gawo lovuta lomwe limayang'aniridwa pakupanga.

8. Kupanga ndi kunyamula:

• Mitu ya methyl ether ether imapangidwa m'magulu osiyanasiyana kuti akwaniritse zofunikira zingapo zamapulogalamu osiyanasiyana. Masukulu osiyanasiyana amatha kusiyanasiyana m'matumba awo, kukula kwa tinthu, ndi zinthu zina.
• Zogulitsa zomaliza zimayikidwa kuti zigawidwe.

Ndikofunikira kudziwa kuti zomwe zagwiritsidwa ntchito ndi zopangidwira zomwe zimagwiritsidwa ntchito mu chiwerewere zimatha kusiyanasiyana malinga ndi njira zomwe wopanga amapanga komanso zomwe mukufuna kwambiri pa celylulose. Methyl cellulose imapeza ntchito mu makampani ogulitsa zakudya, mankhwala ogulitsa, zomanga, ndi magawo ena chifukwa cha mphamvu yake yosungunuka ndi makanema.
