Cellulose ether

Cellulose etherNdi mtundu wa cellulose yochokera ku ma cellulose omwe amasinthidwa mwanjira ina kuti apange mawonekedwe ake ndikupangitsa kuti ikhale yosinthana ndi mafakitale osiyanasiyana. Zimachokera ku cellulose, yomwe ndi polymer yolemera kwambiri yomwe imapezeka m'makoma a cell a mbewu. Cellulose ether imapangidwa ndikuchiritsa cellulose ndi ma reagents mankhwala kuyambitsa magulu oyang'anira pa cellulose, chifukwa chosungunuka bwino, kukhazikika, komanso magwiridwe antchito. Nayi mfundo zazikuluzikulu zokhudzana ndi cellulose ether:

1. Kapangidwe ka mankhwala:

• Cellulose ether imasunga mawonekedwe oyambira a celluuse, omwe ali ndi mayunitsi a shuga omwe amalumikizidwa pamodzi ndi β (1 → 4) zomangira.
• Zosintha zamankhwala zimayambitsa magulu a ether, monga methyl, ethyl, hydroxthyl, hydroxypropyl, carboxymthyl, ndi ena, ku hydroxyl (-Oh) ma molekyulu.

2. Katundu:

• Kusungunuka: Cellulose eders amatha kusungunuka kapena kusungunuka m'madzi, kutengera mtundu ndi kuchuluka kwa zolowa m'malo. Izi zimawapangitsa kukhala oyenera kuti azigwiritsa ntchito mosiyanasiyana.
• Rhelogy: Cellose osintha bwino, a rheology osintha, komanso okhazikika mu madzi amadzimadzi, kupereka mafakisoni amagetsi ndikuwongolera kukhazikika kwa malonda ndi magwiridwe antchito.
• Mapangidwe a filimu: Ma cellulose ena amakhala ndi katundu wamavidiyo, kuwalola kuti apange mafilimu owonda, osinthika akauma. Izi zimawapangitsa kukhala othandiza pophimba, zomata, ndi ntchito zina.
• Kukhazikika: cellulose etres emet chiwonetsero cha PH ndi kutentha, ndikuwapangitsa kuti agwiritse ntchito zosiyanasiyana.

3. Mitundu ya cellulose ether:

• Methylcellulose (MC)
• Hydroxypropyl methylcellulose (hpmc)
• Hydroxyethyl cellulose (hec)
• Carboxymethyl cellulose (cmc)
• Ethyl hydroththyl cellulose (Ehec)
• Hydroxypropyl cellulose (hpc)
• Hydroxyethyl methylcelulose (hemc)
• Sodium carboxymethyl cellulose (nacmc)

4. Mapulogalamu:

• Ntchito Yomanga: OGWIRITSA NTCHITO, osunga madzi, ndi rheology osintha zopangidwa ndi denga la simenti, utoto, zokumba, ndi zomatira.
• Chisamaliro chaumwini komanso zodzikongoletsera: olemba ntchito ngati oundana, okhazikika, tsamba la filimu, ndi ma shalsifera, shampoos, ndi zinthu zina zosamalira pandekha.
• Mankhwala ogwiritsa ntchito mankhwala: ogwiritsidwa ntchito ngati omanga, kusokoneza, omasulidwa, ndi ma viwa omasulidwa, kuyimitsidwa, mafuta, ndi ma gels apamwamba.
• Chakudya ndi zakumwa: Zogwiritsidwa ntchito ngati otsatsa, okhazikika, ma emulsifiers, ndi mawonekedwe osuta mu chakudya monga msuzi, zovala, zakumwa.

5. Kukhazikika:

• Cellulose eds amachokera ku magwero osinthidwa osinthidwa, ndikuwapangitsa kuti azikhala ochezeka a malo opanga ma polima.
• Ndiwo biodegrable ndipo sathandiza kuipitsa zachilengedwe.

Pomaliza:

Ma cellulose ether ndi polima komanso polima polowera m'mafakitale oterowo monga kapangidwe kake, mankhwalawa, mankhwala ogulitsa, ndi chakudya. Mphamvu zake zapadera ndi magwiridwe ake zimapangitsa kuti ikhale yofunikira mu mapangidwe ambiri, omwe amathandizira kugwira ntchito, kukhazikika, komanso mtundu. Pamene mafakitale akupitilizabe kuyika njira zokwanira komanso zothetsera ma eco, zomwe zimapangitsa kuti cellulose ikhale ikuyembekezeka kukula, kukonzanso kwatsopano pamunda uno.
