Hydroxypropyl methylcellulose, e lauiloa foi o le hypromellose ma le cellulose hydroxypropyl methyl ether, e faia mai le cellulose cotton sili ona mama ma e faʻapitoa etherified i lalo o tulaga alkaline.
le eseesega:
uiga eseese
Hydroxypropyl methylcellulose: paʻepaʻe poʻo paʻepaʻe fiber-pei o le paʻu poʻo granules, o loʻo iai i ituaiga eseese e le o ionic i totonu o le paluga cellulose, o lenei oloa o se semi-synthetic, polymer viscoelastic inactive.
Hydroxyethyl cellulose o se paʻepaʻe poʻo samasama, e leai se manogi, e le oona poʻo le paʻu paʻu, o le mea mataʻina autu o le cellulose alkali ma le ethylene oxide etherification, o se mea e le mafai ona soluble cellulose ether.
E ese le faʻaaogaina
I totonu o le fale vali, o le hydroxypropyl methylcellulose o loʻo i ai le solubility lelei i le vai poʻo le solvents organic e pei o se mafiafia, faʻasalalau ma faʻamautu. O le Polyvinyl chloride o loʻo faʻaaogaina e avea o se vali vali mo le faʻamavaeina o le polymerization e saunia ai le polyvinyl chloride, lea e faʻaaogaina lautele i paʻu, pepa oloa, fualaau aina ma fualaau faisua faʻasaoina, textiles ma isi pisinisi.
Hydroxypropyl methylcellulose: toetoe a le mafai ona solu i le ethanol atoatoa, eter, acetone; soluble i le manino po o le turbid colloidal solution i le vai malulu, faʻaaogaina lautele i coatings, inks, fiber, vali, fai pepa, cosmetics, vailaau faʻasaina, minerale Faʻasologa o oloa, suauʻu toe faʻaleleia ma falemaʻi falemaʻi.
eseese solubility
Hydroxypropyl methylcellulose: toetoe a le mafai ona solu i le ethanol atoatoa, eter, acetone; solu i totonu o le vai malulu.
Hydroxyethyl cellulose (HEC): E mafai ona saunia vaifofo i laina viscosity eseese, ma e iai mea lelei e fa'amama masima mo electrolytes.
