Ts'ebetso bakeng sa moetsi oa methyl celllolose ether

Sebopeho saMethyl cellulose EtherE kenyelletsa phetoho ea lik'hemik'hale tsa cellulose ea cellulose ka karabelo ea chelete e ngata. Methyl cellulosese (MC) ke cellulose ea metsi a qhibilihileng e sebelisoang haholo indastering e fapaneng. Mona ke kakaretso e akaretsang ea ts'ebetso bakeng sa tlhahiso ea methyl cellinglose ether:

1. Khetho ea mohloli oa khomphutha:

• Ts'ebetso e qala ka khetho ea mohloli oa Cellulose, o tsoa ho pulp kapa k'hothone. Mohloli oa Cellulose o khethoa ho latela litšobotsi tse lakatsehang tsa sehlahisoa sa methyl cemllose.

2. Ho puruela:

• Mohloli o khethiloeng o khethiloeng o ntse o putlama, ketso e tlohelang likhoele e le sebopeho se laoleng haholoanyane. Ho phatloha ho ka fihlelleha ka mekhoa ea mochini kapa ea lik'hemik'hale.

3. Ts'ebetso ea cellulose:

• Cliblease e nang le celpeddle e butsoe ka ho e tšoara ka tharollo ea alkanaline. Mohato ona o ikemiselitse ho ruba li-pubers tsa cellulose, li li etsa hore li ntlafale nakong ea karabelo e latelang ea phetheho.

4. Karabelo ea Etheright:

• Ke lihlopha tse sebetsang li se li le teng, moo etherey, lihlopha tsa methyl.
• Karabelo ea menyetla e kenyelletsa ts'ebeliso ea mahlahana a methylate e kang sodium hydroxide le methyl chloride kapa dimethyl sulfate. Maemo a hau a karabelo, ho kenyelletsa mocheso, khatello le ho arabela, li laoloa ka hloko ho fihlela tekanyo e batlang e le ea ho nka sebaka sa nako (DS).

5. Nontorazation le ho hlatsoa:

• Kamora karabelo ea menyetla, sehlahisoa ha se nke lehlakore ho tlosa alkali e feteletseng. Mehato e latelang e hlatsoang e etsoa ho tlosa lik'hemik'hale tse setseng.

6. Ho omella:

• Clloulose e hloekisitsoeng le e nang le methyla e omisitsoeng ea ho fumana sehlahisoa sa methyl sembolose sentseng ka mokhoa oa phofo kapa granules.

7. Taolo ea boleng:

• Mekhoa e mengata ea tlhahlobo, ho kopanyelletsa le matla a nyutlelie (nmr) Spectroroscopy Tekanyo ea sebaka (DS) ke thomello e makatsang nakong ea tlhahiso.

8. Ho theha le ho sephutheloana:

• Methyl cellulose ether o theha limaraka tse fapaneng ho fihlela litlhoko tse itseng tsa likopo tse fapaneng. Masira a fapaneng a ka fapana ka lintho tsa bona, boholo le thepa e meng.
• Lihlahisoa tsa ho qetela li rekisoa hore li tsamaisoa.

Ho bohlokoa ho hlokomela hore maemo le litlatsetso tse itseng tse sebelisoang ka mokhoa o ikhethileng li ka fapana ho latela lits'ebetso tsa moetsi le thepa eo u e bonang. Methyl cellulose e fumana likopo indastering ea lijo, methcectical, kaho ea kaho ea methapo ea metsi le e etsang filimi.
