Methocel A4C & A4M (Cellulose Eter)

Methocel (Methyl Cellulose) Va'aiga lautele:

O le Methocel o se igoa fa'ailoga mo le methyl cellulose, o se ituaiga o cellulose ether na gaosia e le Dow. Methyl cellulose e maua mai le cellulose e ala i le suia o vaega hydroxyl ma vaega methyl. E fa'aaogaina lautele i alamanuia eseese ona o lona solu vai ma mea e fai ai ata.

Uiga Lautele ole Methyl Cellulose (Methocel):

  1. Suavai Solubility:
    • Methyl cellulose e sili ona solu i le vai, e fai ai ni vaifofo manino ma viscous.
  2. Pulea Viscosity:
    • E avea o se vailaʻau mafiafia lelei, e fesoasoani i le faʻatonutonuina o le viscosity i faʻatulagaga.
  3. Meatotino Fausia Ata:
    • Methyl cellulose o loʻo i ai le gafatia e fai ata tifaga, e talafeagai ai mo faʻapipiʻi ma faʻapipiʻi vailaʻau.
  4. Fa'amau ma fa'apipi'i:
    • E galue e pei o se fusifusia i totonu o vailaʻau vailaʻau ma e mafai ona faʻaaogaina e fai ma faʻapipiʻi i faʻaoga eseese.
  5. Fa'amautu:
    • Methyl cellulose e mafai ona galue o se faʻamautu i emulsions ma suspensions, faʻaleleia le mautu o faʻatulagaga.
  6. Taofi Suavai:
    • E tutusa ma isi cellulose ethers, o le methyl cellulose o loʻo faʻaalia ai mea e taofi ai le vai, e fesoasoani i le faʻaleleia atili o galuega i mea faufale.

Dow Methocel A4C ma le A4M:

A aunoa ma ni fa'amatalaga patino e uiga i le Methocel A4C ma le A4M, e faigata tele le tu'uina atu o fa'amatalaga auiliili. O togi o oloa i totonu o le laina Methocel atonu e iai ni fesuiaiga i uiga e pei ole viscosity, mamafa mole, ma isi mea patino. E masani lava, e tu'uina atu e le au gaosi fa'amatalaga fa'amatalaga fa'atekinisi mo vasega ta'itasi o oloa, e tu'uina atu fa'amatalaga e uiga i le viscosity, solubility, ma fa'atonuga o talosaga.

Afai o lo'o e su'eina ni fa'amatalaga sa'o e uiga i le Methocel A4C ma le A4M, ou te fautuaina le siakiina o fa'amaumauga aloa'ia a le Dow, e aofia ai pepa o fa'amatalaga o oloa pe fa'afeso'ota'i sa'o le Dow mo fa'amatalaga sili ona sa'o ma fa'aonaponei. E masani ona tu'uina atu e le au gaosi oloa le lagolago fa'apitoa ma fa'amaumauga e fesoasoani ai i tagata fa'aoga i le filifilia o le togi talafeagai mo a latou talosaga fa'apitoa.

Fa'amolemole maitau o fa'amatalaga o oloa ma fa'aputuga e mafai ona fa'atatau i fa'afouga po'o suiga a tagata gaosi oloa, o lea e fautuaina ai le siaki ma le Dow mo fa'amatalaga lata mai.
