Cellulose ana navanazvo uye nzira yekugadzira zvakafanana

Kugadzirwa kwecellulose etanainosanganisira nhevedzano yemakemikari yekugadziridzwa kune cellulose, zvichikonzera mukati mevakatorwa nezvinhu zvakasiyana. Izvi zvinotevera general pamucheto nzira dzinoshandiswa kubereka cellulose etana:

1. Kusarudzwa kweCellulose Source:

• Cellulose etana inogona kuverengerwa kubva kune dzakasiyana siyana manhamba akadai sehuni dzemapuranga, machira ekotoni, kana zvimwe zvinhu zvinodyarwa. Sarudzo yeCellulose Source inogona kukanganisa hunhu hweiyo yekupedzisira cellulose etera chigadzirwa.

2. PUBPING:

• Iyo cellulose sosi inodonha ichiputira kuti iperere mafambiro mune fomu inokwanisa. PURPE inogona kuwanikwa kuburikidza nemuchina, makemikari, kana musanganiswa wenzira mbiri idzi.

3. Kunatswa:

• Iyo yakakomberedzwa cellulose inoiswa pasi pekuchenesa maitiro kubvisa kusvibiswa, lignin, uye zvimwe zvisiri-cellulosic zvikamu. Kucheneswa kwakakosha kuti uwane iyo yakakwira-mhando cellulose zvinhu.

4. Activation of cellulose:

• Iyo yakacheneswa cellulose inoitwa nekuzvimba iyo mune yeAlkaline Solution. Iyi nhanho yakakosha yekugadzira iyo cellulose yakawanda panguva inotevera yekuchinja kwetsoka.

5. Etiation maitiro:

• Iyo yakagadziriswa cellulose inotsvaga endeges, uko mapoka ether anounzwa kumapoka eHydroxyl paCellulose Polymer Chain. Zvakajairika kugadzirira vamiririri vanosanganisira ethylyone oxide, profyle oxide, sodium chloroacetate, methyl chloride, uye vamwe.
• Kuita kwacho kunowanzoitwa pasi pemamiriro ezvinhu ekudzora ekudziya, kumanikidzwa, uye pH kuzadzisa degree rekutsiva (DS) uye kudzivirira maitiro.

6. Kusaruramisa nekugeza:

• Mushure mekutsauka kwekuchinja, chigadzirwa chinowanzoradziswa kubvisa zvakawandisa reagents kana ne-zvigadzirwa. Inotevera nzvimbo dzekushambidza dzinoitwa kubvisa makemikari akasara uye kusachena.

7. Kuomesa:

• Iyo yakanatswa uye itsits cellulose inoomeswa kuti uwane iyo yekupedzisira cellulose etera chigadzirwa mune poda kana granular fomu.

8. Hunhu kutonga:

• Maitiro akasiyana-siyana ekuongorora, kusanganisira nuclear magineti resonance (NMR) spectroscopy, yechina-inoshandura infrared (ftir) spectroscopy, uye chromatography, anoshandirwa kudzora kwemhando. Iyo DS inotariswa zvakanyanya kuti ive nechokwadi chekuenderana.

9. Kuumbika uye application:

• Iyo cellulose ether inobva yavezwa mumakiredhi akasiyana kuti isangane nezvinodiwa zvezvinhu zvakasiyana siyana zvekushandisa zvakasiyana siyana. Yakasiyana cellulose ana avanemi mashiripiti akasiyana, akadai sekuvaka, mishonga, chikafu, chejasi, uye zvimwe.

Izvo zvakakosha kuti uzive kuti nzira dzakasarudzika uye mamiriro ezvinhu anogona kusiyana zvichienderana neyeinodiwa cellulose etera chigadzirwa uye chinongedzo. Vagadziri vanowanzo shandisa procrietary processes kuti vagadzire cellulose ana vana nezvirevo zvakarongedzwa kuti vasangane nezvinodiwa zvemaindasitiri madhiri.
