O le a le MHEC?

Methyl Hydroxyethyl Cellulose (MHEC) o se cellulose ether derivative lautele faʻaaogaina i alamanuia e pei o le fausiaina, vailaʻau, ma mea tau tausiga a le tagata lava ia.E fa'apipi'iina e ala i le fa'afo'iina o le cellulose ma le ethylene oxide ma le methyl chloride, ma fa'atupuina ai se tu'ufa'atasi ma vaega uma o le hydroxyethyl ma le methyl o lo'o fa'apipi'i i le ponaivi o le cellulose.

E fa'asoa e le MHEC le tele o meatotino ma isi cellulose ethers e pei o le Hydroxypropyl Methylcellulose (HPMC) ma le Hydroxyethyl Methylcellulose (HEMC), e aofia ai:

1. Taofi Suavai: O le MHEC o loʻo i ai le malosi e faʻafefe ma taofi ai le vai, faʻaaogaina i mea faufale e pei o le sima, grouts, ma faʻapipiʻi tile e puipuia ai le vave faʻagogo ma faʻaleleia le faʻaogaina.
2. Mafiafia: E mafai ona faʻapupulaina le viscosity o faʻamaʻi vai, lea e aoga i faʻaoga e pei o vali, faʻapipiʻi, ma mea tau tausiga a le tagata lava ia e ausia ai le manaʻoga tutusa.
3. Fa'amautu: E fesoasoani le MHEC e fa'amautu emulsions ma fa'amalologa, puipuia le vaeluaga o vaega ma fa'atumauina le tutusa o oloa.
4. Faiga Ata: E tutusa ma isi cellulose ethers, e mafai e le MHEC ona fausia se ata manifinifi pe a faʻaoga i luga, e maua ai le puipuiga ma le faʻaleleia o le pipii.
5. Faʻaleleia Meatotino Faʻafefe: E mafai ona faʻaleleia uiga tafe o faʻasologa, faʻafaigofie le gaioiga ma le faʻaogaina.

O le MHEC e masani ona filifilia mo lona tuʻufaʻatasiga faʻapitoa o meatotino, e pei o lona gafatia e tuʻuina atu lelei le faʻamauina o le vai aʻo faʻamauina le viscosity maualalo pe a faʻatusatusa i isi cellulose ethers.Ole mea lea e fa'apitoa ai mo fa'aoga o lo'o mana'omia ai le fa'atumauina o le vai maualuga e aunoa ma le fa'ateleina o le viscosity o le fa'apipi'i.

Methyl Hydroxyethyl Cellulose (MHEC) o se cellulose ether derivative faʻatasi ma le tele o faʻaoga, lea e matua taua tele ai ona meatotino e pei o se mafiafia, faʻamautu, vai faʻamau, ma ata tifaga.
