Phase maitiro uye kuumbwa kweiyo fiBril mune manyorerwo cellulose etana

Chimiro cheChikamu uye Filbril Formation mune Mukaticellulose etanaIzvo zviitiko zvakaomesesa zvinopindirwa nemakemikari emakemikari eCellulose anaTersinwe, kusvinura kwavo, tembiricha, uye kuvapo kwezvimwe zvinopindwa. Cellulose ana ana metdroxyprupyl methylcellose (HPMC) uye CarboxyMelm Cellylosel Cellever (CMC), anozivikanwa nekuda kwekugona kwavo kuumba maGels uye kuratidza chinonakidza chikamu chinjana. Heano general Overview:

Chiitiko Chekuita:

1. Sol-Gel Shanduko:
   • Mhinduro dzemukati dze cellulose etana kazhinji dzinowanzo shandurwa-gel-gel kushandurwa sekuwedzera kwekuwedzera.
   • Pazvakadzama, mhinduro inozvibata kunge mvura (sol), ichiri pakakwirira, inoumba chimiro cheGel.
2. Inoshoropodza Golation Concentration (CGC):
   • CGC ndiko kusungwa uko kushandurwa kunobva mumhinduro kune gel kunoitika.
   • Zvinhu zvinopesvedzera CGC inosanganisira iyo degree rekutsiva kweCellulose Ether, tembiricha, uye kuvapo kwemazaru kana zvimwe zvinowedzera.
3. Tembiricha kuvimba:
   • GLALLE kazhinji tembiricha-inotsamira, neimwe cellulose eter kuburitsa yakawedzera gwenzi pakupisa kwakanyanya.
   • Iyi tembiricha yekudziya inoshandiswa mukushandisa sekushandiswa kwezvinodhaka kusunungurwa uye kugadzirisa chikafu.

FiBril Kuumbwa:

1. Micellar Aggregation:
   • Pane zvimwe kutarisisa, cellulose etiers inogona kuumba micelles kana ekuunganidza mumhinduro.
   • Iyo Aggregation inotungamirwa neiyo hydrophobic kutaurirana kweiyo alkyl kana hydroxylinkyl mapoka akaunzwa panguva yekutsva.
2. Fibrillogeneis:
   • Shanduko kubva kuSoluble Polymer maketani kune Insoluble filbril inosanganisira maitiro anozivikanwa seFrilillogeneS.
   • Fibrils inoumbwa kuburikidza neyekufambidzana nezvekudyidzana, hydrogen kusungwa, uye kukanganisa kwemuviri wemapolymer.
3. Simba reShear:
   • Kushandiswa kwemasimba eshear, sekukurudzira kana kusanganisa kana kusanganisa, kunogona kusimudzira kuumbwa kwemafuta mu cellulose ether mhinduro.
   • Zvivakwa zveShear-zvinokatyamadza zvinoenderana nemaindasitiri maitiro uye maapplication.
4. Kuwedzera uye kuyambuka:
   • Kuwedzerwa kwemaronda kana mamwe mahombe anogona kupesvedzera kuumbwa kwemidziyo yefubrillar.
   • Crosslinking vamiririri vanogona kushandiswa kusimbisa uye kusimbisa filbrils.

Zvishandiso:

1. Dhirowa Dhirowa:
   • Green uye fibril fomu yekuumbwa ye cellulose ana ana ana inoshandiswa mukudzora zvinodhaka zvinodhaka.
2. Indasitiri yechikafu:
   • Cellulose ana ana anomirira pakugadzira uye kugadzikana kwezvinhu zvekudya kuburikidza negwenzi uye kureruka.
3. Zvigadzirwa zvega zvega:
   • GLALLE uye FIBBBB FORTING SEATINCE YEKUSVIRA MABASA REMADZIMAI SEZVAKAITWA, ROPA, NEZVINHU ZVINOGONESA.
4. Zvivakwa zvekuvaka:
   • MaGenational Properties akakosha mukuvandudzwa kwezvinhu zvekuvaka senge tile anomhara uye mongwe.

Kunzwisisa maitiro ezve chikamu uye fiBril yekuumbwa kwe cellulose anaiters yakakosha kuti ive yavo manhamba avo ezvinyoreso. Vatsvagiri uye vaongorori vanoshanda kuti vabate zvinhu izvi zvekushanda zvakavanzika mumaindasitiri akasiyana-siyana.
