O le a le Cellulose Ethers ma aisea e faʻaaogaina ai?

Cellulose ethers o polymers solu vai e faia mai le cellulose, o le vaega autu o le fausaga o laau. E tele ituaiga o cellulose ethers, e tofu ma mea fa'apitoa e fa'apena ona lelei mo fa'aoga eseese.

O togi fa'apitoa o cellulose ethers o lo'o fa'aaogaina i mea uma mai vaila'au ma mea teuteu i le fausiaina ma le gaosiga o ie. E le gata i lea, o loʻo faʻaaogaina e avea ma meaʻai faʻapipiʻi ma mafiafia i vali ma paʻu.

Ituaiga cellulose ethers

O ituaiga sili ona taatele e tolu o cellulose ethers o le hydroxypropylmethylcellulose (HPMC), methylhydroxyethylcellulose (MHEC).

Ona o lona agavaʻa, HPMC o le ituaiga sili ona faʻaaogaina o le cellulose ether. E maua i vasega eseese ma eseese mole mamafa mamafa, tikeri o le suitulaga ma viscosities. E mafai ona fa'aogaina le HPMC i vaifofo fa'ama'i ma alkaline, ma fa'amalieina mo le tele o fa'aoga.

O le MHEC e tutusa ma le HPMC ae o loʻo i ai le maualalo o le hydroxypropyl content. Pe a faatusatusa i le HPMC, o le vevela o le gelation o le MHEC e masani lava ona maualuga atu i le 80 °C, e faalagolago i le vaega o mea e aofia ai ma le gaosiga o metotia. MHEC e masani ona faʻaaogaina e avea o se mafiafia, fusi, faʻamautu faʻamautu poʻo se ata tifaga muamua.

Cellulose ethers e tele fa'aoga ona o latou uiga fa'apitoa. O nisi faʻaoga masani o cellulose ethers e aofia ai:

Mea Mafiafia: E mafai ona faʻaaogaina le ethers cellulose e fai ma mea mafiafia mo lubricants, faʻapipiʻi, vailaʻau faʻamaʻi suauu, meaʻai, mea teuteu, ma vailaʻau.

Fa'apipi'i: E mafai ona fa'aogaina le cellulose ethers e fai ma fa'amau i papa po'o granules. Latou te faʻaleleia le faʻapipiʻiina o paʻu aʻo tumau pea le lelei o le tafe.

Emulsion Stabilizers: E mafai e le cellulose ethers ona fa'amautu fa'aluega e ala i le puipuia o le fa'atasi po'o le fa'aputuina o matāua ta'ape vaega. O le mea lea e lelei ai mo le fa'aogaina i polymers emulsion pei o vali latex po'o mea fa'apipi'i.

Mea fai ata tifaga: E mafai ona fa'aoga le cellulose ethers e fai ai ata po'o fa'alavalava i luga o luga. E masani ona faʻaaogaina i mea faufale e pei o taʻavale poʻo pepa faʻapipiʻi faʻapipiʻi. O ata tifaga e faia mai i le cellulose ethers e masani ona manino ma fetuutuunai, ma le lelei o le susu.
