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-ionic i totonu o le paluga cellulose, o lenei oloa o se semi-synthetic, polymer viscoelastic inactive.
Hydroxyethyl cellulose o se pa'epa'e po'o samasama, odorless, non-o'ona alava po o le pa'u malosi, o le mea mata autu o alkali cellulose ma ethylene oxide etherification, lea o se eter cellulose soluble e le ionic.
E ese le faʻaaogaina
I totonu o le fale vali, o le hydroxypropyl methylcellulose o loʻo i ai le solubility lelei i totonu o le vai poʻo soʻo se mea faʻapipiʻi e pei o se mafiafia, faʻasalalau ma faʻamautu.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 pepa, 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 in transparent or turbid colloidal solution in cold water, fa'aaoga lautele i coatings, inks, fibers, dyeing, papermaking, cosmetics, pesticides, minerals Fa'agaioiga o oloa, suau'u toe fa'aleleia ma alamanuia pharmaceutical.
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 faʻafefeteina masima mo electrolytes.
