Maitiro ekugadzira methyl cellulose ether

Kugadzirwa kwemethyll cellulose etherinosanganisira kugadziridzwa kwemakemikari kwe cellulose kuburikidza nekutsungirira maitiro. Methyll Cellulose (MC) inguva-soluble cellulose ther yakashandiswa zvakanyanya mune dzakasiyana-siyana maindasitiri. Heano general treview of maitiro ekugadzira methyl cellulose ether:

1. Kusarudzwa kweCellulose Source:

• Maitiro acho anotanga nesarudzo yemheremalose source, inowanzovambwa kubva kune huni prot kana machira. Iyo cellulose sosi inosarudzwa kubva pane inodiwa maitiro eiyo yekupedzisira methyl cellulose chigadzirwa.

2. PUBPING:

• Iyo yakasarudzwa cellulose sosi inodonhedza kuputika, maitiro anovhuna pasi mafambiro mune fomu inokwanisa. PURPE inogona kuwanikwa kuburikidza nemuchina kana nzira dzemakemikari.

3. Activation of cellulose:

• Iyo yakakomberedzwa cellulose inoshandiswa nekuibata nekuibata neAlkaline Solution. Iyi nhanho inovavarira kuzvimba cellulose machira, kuvaita kuti vatorezve panguva inotevera yekuchinja kwekuchinja.

4. Etified maitiro:

• Iyo yakagadziriswa cellulose inotsausaes, uko mapoka e mapoka, mune ino mapoka, methyl mapoka, anounzwa kumapoka eHydroxyl paCellulose Polymer Chain.
• Iyo ertification kuita inosanganisira kushandiswa kweiyo methylating vamiririri senge sodium hydroxide uye methyl chloride kana dimethyl sulfate. Mamiriro ezvinhu ekuita, kusanganisira tembiricha, kumanikidzwa, uye maitiro ekuita, anodzorwa nekuchenjera kuti awane degree raunoda kwekutsiva (DS).

5. Kusarerekera uye kugeza:

• Mushure mekuchinja kwekuchinja, chigadzirwa chakarerekera kubvisa alkali yakawandisa. Inotevera kugeza matanho anoitwa kuti abvise makemikari akasara uye kusviba.

6. Kuomesa:

• Iyo yakanatswa uye methylated cellulose inoomeswa kuti uwane iyo yekupedzisira methyl cellulose etera chigadzirwa muchimiro cheupfu kana granules.

7. Hunhu Control:

• Maitiro akasiyana-siyana ekuongorora, kusanganisira nuclear magineti resonance (NMR) spectroscopy, yechina-inoshandura infrared (ftir) spectroscopy, uye chromatography, anoshandirwa kudzora kwemhando. Dhigirii rekutsiva

8. Kuumbika uye kurongedza:

• Methyl Cellulose ether anobva aumbwa mumakiredhi akasiyana kuti asangane nezvinodiwa zvakasiyana siyana zvekushandisa zvakasiyana siyana. Mamakisi akasiyana anogona kusiyana muViscosity yavo, saizi yehukuru, uye zvimwe zvinhu.
• Zvigadzirwa zvekupedzisira zvakagadzirirwa kugoverwa.

Izvo zvakakosha kuti zviitike kuti mamiriro chaiwo uye mamwe marekodhi anoshandiswa mune erfitifitifitifitifitification yekuita zvichigona kusiyana pachinhu cheMugadziri cheMugadziri uye chivakwa chemaCellul Cellulose chigadzirwa. Methyl Cellulose inowana mafomu mune indasitiri yechikafu, mishonga yemishonga, kuvaka, uye mamwe zvikamu nekuda kwekugona kwayo kwemvura-solubility.
