Cellulose etana: Tsanangudzo, kugadzira, uye application

Tsanangudzo yeCellulose anaTers:

Celleulose anaana mhuri yePolulble Polymers yemvura inotorwa kubva kuCellulose, polysaccharide inowanikwa mumasero emaruva ezvirimwa. Kuburikidza nemakemikari kugadziridzwa, ether mapoka anounzwa kune cellulose backbone, zvichikonzera mukati mezvikamu zvezvivakwa zvakadai sekusanzwisisa mvura, kugona kugona, uye kugona kwemafirimu. Mhando dzakajairika dze cellulose aungana zvinosanganisiraHydroxypruppropyl methylcellose(HPMC), CarboboyMethyl Cellerose (CMC), HydroxyTH Cellulose (Hec), Methyl Cellulose (MC), uye EtHyl Cellulose (EC).

Kugadzira Cellulose anaVana:

Maitiro ekugadzira mheremalose etana anowanzo kusanganisira matanho anotevera:

1. Cellulose Source Sarudzo:
   • Cellulose inogona kutwaswa kubva kune huni remapuranga, machira ekotoni, kana zvimwe zvigadzirwa-zvakavakirwa.
2. Pulping:
   • Iyo yakasarudzwa cellulose inovhuvhuta ichiputika, ichiputsa mafambiro mune fomu inogoneka.
3. Activation of cellulose:
   • Iyo inodhonza cellulose inoitwa nekuzvimba iyo mune alkaline solution. Iyi nhanho inoita kuti cellulose zvakanyanya pamuchinjiko panguva inotevera kuwedzerwa.
4. Etified maitiro:
   • Ether mapoka (semuenzaniso, methyl, hydroxyprichyl, carboxymethyl) anounzwa kune cellulose kuburikidza nemakemikari maitiro.
   • Zvakajairika kugadzirira vamiririri vanosanganisira alkylene oxides, alkyl mersides, kana zvimwewo reagents, zvichienderana neyekuda kudiwa cellulose ether.
5. Kusarerekera nekugeza:
   • Iyo itstsime cellulose inosemesa kubvisa yakawandisa reagents uye wobva washambwa kubvisa kusvibiswa.
6. Kuomesa:
   • Iyo yakanatswa uye itsits cellulose yakaomeswa, inokonzerwa nemari yekupedzisira cellulose etera chigadzirwa.
7. Hwakanaka Kudzora:
   • Maitiro akasiyana-siyana ekuongorora, akadai seNMR spectroscopy uye ftir spectroscopy, anoshandirwa nekuda kwekutonga kwemhando kuti ive nechokwadi chekutsiva nekuchena.

Kushandiswa kweCellulose anaitani:

1. Indasitiri yekuvaka:
   • Tile Adhire, Motoro, Anopa: Ipa Kuchengeta mvura, kuvandudza basa rekushanda, uye kuwedzera kudiwa.
   • Kuzvimiririra makomendi: Kuvandudza kuyerera zvivakwa uye kusimbisa.
2. Mishonga:
   • Forat For modelation: Ita seBinders, disintegrapants, uye vamiririri vanogadzira mafirimu.
3. Indasitiri yechikafu:
   • Thiziges uye Stabilizer: Inoshandiswa mune dzakasiyana siyana zvekudya zvigadzirwa kuti upe viscosity uye kugadzikana.
4. Coatings uye pendi:
   • Pendi-dzakavakirwa mvura.
   • COMECEUCUTICAL COATings: Inoshandiswa kune inodzorwa-kuburitswa mafomu.
5. Zvigadzirwa zvega zvega:
   • Shampoos, lotions: ita seiri thizili uye stabilizers.
6. Mahwira:
   • Mahwira akasiyana-siyana: Kuvandudza viscosity, kuderedza, uye zvimiro zvetsiva.
7. Mafuta negesi Indasitiri:
   • Kudhirowa mvura: Ipa rheological kutonga uye fluid kurasikirwa kuderedzwa.
8. Indasitiri yepepa:
   • Pepa rinobatanidza uye sizzes: kuvandudza bepa resimba, kuunganidzira kushushikana, uye kurongeka.
9. Zvinyore:
   • Textile sizzes: Kuvandudza kudeya uye kuumbwa kwemafirimu pane zvinyorwa.
10. Zvigadzirwa zvega zvega:
    • Cosmetics, madesheni: ita sehana uye stabilizers.

Cellulose etana anowana kushandiswa kwakapararira nekuda kwezvivakwa zvavo zvevose, zvinopa mukuita kwezvinhu zvakasiyana siyana zvezvigadzirwa mumaindasitiri akasiyana. Sarudzo ye cellulose ether zvinoenderana neyakagadziriswa application uye inodiwa zvivakwa.
