Chemistry of mercel ™ cellulose eva

Nzira™ rudzi rwevanhu vanombo cellulose etero rinogadzirwa neDow. Aya ma cellulose eter anotorwa kubva ku cellulose, polymer yakasikwa inowanikwa mumasero emasero. Iyo chemistry yeThecel ™ inosanganisira kugadziridzwa kwemheremalose kuburikidza nekuchinja maitiro. Mhando yekutanga yeThecel ™ inosanganisira hydroxyprusyl methylcellose (HPMC) uye methylcellose (mc), imwe neimwe ine chaiyo yemakemikari maitiro. Heano general Ongororo yeChemistry yeThecel ™:

1. Hydroxyprusyl methylcellose (HPMC):

• Chimiro:
  • HPMC iri mvura-inokweretesa cellulose ether ine maviri anokwana maviri ekisheni: HPDROPPROPYL (HP) uye methyl (m) mapoka.
  • Iyo hydroxyprupropyl mapoka inosuma hydrophilic mashandiro, inosimudzira mvura yemvura.
  • Iwo methyl mapoka anopa pachena solubility uye kukanganisa zvinhu zve polymer.
• Etified maitiro:
  • HPMC inogadzirwa kuburikidza nekutsva kweCellulose neProulse Oxide (yeHydroxyPropyl Mapoka) uye methyl chloride (ye methyl mapoka).
  • Mamiriro ezvinhu ekuita anonyatso kudzorwa kuti uwane iyo inodiwa degree rekutsiva
• Zvivakwa:
  • HPMC inoratidzira yakanakisa mvura solubility, firimu-inoumba zvivakwa, uye inogona kupa kudzorwa kusunungurwa mune mishonga yemishonga.
  • Iyo degree rekutsiva dzinopesvedzera zvevisimiki zvePolymer, kuchengetwa kwemvura, uye zvimwe zvinhu.

2. Methylcellose (MC):

• Chimiro:
  • MC ndeye cellulose ether ne methyl subsituents.
  • Zvakafanana neHPMC asi inoshaya iyo hydroxyprupropropyl mapoka.
• Etified maitiro:
  • MC inogadzirwa nekutsvaga cellulose ine methyl chloride.
  • Mamiriro ezvinhu ekuita anodzorwa kuti uwane iyo yakadiwa degree rekutsiva.
• Zvivakwa:
  • MC iri mvura-inokanda uye ine zvikumbiro mumishonga yemishonga, kuvaka, uye maindasitiri ezvekudya.
  • Iyo inoshandiswa seye binder, thickener, uye stabilizer.

3. Zvakajairika zvivakwa:

• Solubil Solubility: ose HPMC uye MC akanyudzwa mumvura inotonhora, achigadzira mhinduro dzakajeka.
• Film formation: Ivo vanogona kuumba zvinochinja uye mafashama mafirimu, kuvaita kuti vabatsire mune dzakasiyana siyana application.
• Kukakavara: Njanisi ™ Cellulose eva vanoita sevhisi inoshanda, vachipesvedzera visikoka.

4. Zvikumbiro:

• Mishonga yemishonga: inoshandiswa muzvipfeko piritsi, mabhenji, uye kudzora-kusunungura mafomu.
• Kuvakwa: akashandirwa muMorsa, Tile Adhireke, uye zvimwe zvekuvaka.
• Chikafu: Inoshandiswa sehana uye stabilizer mune zvigadzirwa zvekudya.
• Kuchengeta Kwemunhu: Inowanikwa Mune Cosmetics, Shampoos, uye zvimwe zvinhu zvega zvega.

Chemistry yeThecelose ™ Cellucose ™ mheremalose idzo dziine zvinhu zvakasiyana nehuremu hwakawanda hwekushandisa, kupa kutonga pamusoro pezvivakwa, kuchengetwa kwemvura, uye humwe hunhu hunokosha mune dzakasiyana siyana mafambiro. Izvo zvakananga zvivakwa zvinogona kugadziriswa nekugadzirisa iyo degree rekutsiva uye kumwe kuongororwa ma parameter.
