Cellulose-Hydroxyethyl Methylcellulose mo le fa'apipi'i fa'ameamea

Le faʻatinoga o le hydroxyethyl methylcellulose i le faʻapipiʻi sima: lelei le anti-sag effect, umi le tatalaina o le taimi, maualuga le malosi vave, malosi maualuga le fetuunaiga o le vevela, faigofie ona faʻafefe, faigofie ona faʻaogaina, naifi e le faʻapipiʻi, ma isi.

O meatotino

Suavai solubility ma mafiafia gafatia: Hydroxyethyl methylcellulose e solu i le vai malulu, fausia se vaifofo manino ma viscous.

E faigofie ona solu i solu fa'aletino: Ona o le i ai o se aofa'iga o vaega hydrophobic methoxy, o le hydroxyethyl methylcellulose e mafai ona solu i nisi solvents organic ma solvents lea e fa'afefiloi ai vai ma mea fa'aola.

Fa'apalepale masima: Talu ai o le hydroxyethyl methylcellulose o se mea e le-ionic, e le-polymer electrolyte, e matua mautu i vaifofo vai o masima u'amea po'o eletise eletise.

Gaoioiga i luga: O vaifofo vai o le hydroxyethyl methylcellulose o lo'o galue i luga ma o le mea lea e i ai se aafiaga emulsifying.

Gelation vevela: A faʻavevela i luga aʻe o se vevela patino, o le hydroxyethyl methylcellulose aqueous solution o le a opaque ma faʻafefe, ma mafua ai ona leiloa le viscosity o le vaifofo. Ae faasolosolo malie ma liua i le tulaga muamua fofo. O le vevela lea e tupu ai le coagulation ma le timuga e faʻatatau i le ituaiga o oloa, le faʻaogaina o le fofo ma le faʻamafanafanaina.

E maualalo le pefu: Talu ai o le hydroxyethyl methylcellulose e le-ionic ma e mafai ona faʻamamaina lelei i le vai vevela i le taimi o le sauniuniga, o le afu e maualalo tele.

PH mautu: O le viscosity o le hydroxyethyl methylcellulose vaifofo vai e tau le afaina i alkali. O lenei oloa e matua mautu i totonu ole pH vaega ole 3.0-11.0.

Aafiaga vai-taofia: Talu ai o le hydroxyethyl methylcellulose o le hydrophilic ma o lona vaifofo vai e maualuga le viscosity, faʻaopoopo i le sima, faʻapipiʻi, vali, ma isi mea e mafai ona faatumauina le maualuga o le suavai o le oloa.

Fa'amauina o foliga: Fa'atusatusa i isi polymers solu vai, o le vaifofo vai o le hydroxyethyl methylcellulose e iai mea fa'apitoa viscoelastic. E fa'aopoopoina fa'apipi'i e fa'aleleia atili ai le agava'a o mea sima fa'ama'i e fa'atumauina o latou foliga.

Lubricity: O le fa'aopoopoina o lenei oloa e mafai ona fa'aitiitia ai le fete'ena'iga o oloa sima ma fa'ameamea ma fa'aleleia atili le lubricity.

Meatotino e fai ata tifaga: Hydroxyethyl methylcellulose e mafai ona fausia ni pepa malo, fetuutuunai, manino ma le suauu lelei ma le ester. E mafai ona matua fa'atuputeleina le viscosity o sima sima. O le faʻaaogaina o le sima fou ma le viscosity talafeagai e mafai ona tumau mautu e aunoa ma le tafe toto mo se vaitaimi patino, faʻafaigofie tele le faʻalelei ma faʻaleleia lelei le faʻatinoga o le fausiaina.
