Hydroxypropyl methylcellulose, inozivikanwawo se hypromellose uye cellulose hydroxypropyl methyl ether, inogadzirwa kubva kune yakachena kwazvo donje cellulose uye inonyanya kunyudzwa pasi pemamiriro ealkaline.
musiyano:
maitiro akasiyana
Hydroxypropyl methylcellulose: chena kana chena faibha-senge poda kana magranules, ari emarudzi akasiyana-siyana asiri-ionic musanganiswa we cellulose, chigadzirwa ichi isemi-synthetic, isingashande viscoelastic polymer.
Hydroxyethyl cellulose ichena kana yero, isinganhuwi, isina-chepfu faibha kana upfu hwakasimba, chinhu chikuru mbishi ialkali cellulose uye ethylene oxide etherification, iyo isiri-ionic soluble cellulose ether.
Kushandiswa kwakasiyana
Muindasitiri yependi, hydroxypropyl methylcellulose ine yakanaka solubility mumvura kana organic solvents seyakakora, dispersant uye stabilizer.Polyvinyl chloride inoshandiswa sependi inobvisa kumiswa kwepolymerization kugadzirira polyvinyl chloride, iyo inoshandiswa zvakanyanya mumatehwe, zvigadzirwa zvemapepa, kuchengetedza michero nemiriwo, machira uye mamwe maindasitiri.
Hydroxypropyl methylcellulose: inenge isingawaniki mune absolute ethanol, ether, acetone;soluble in transparent or turbid colloidal solution mumvura inotonhora, inoshandiswa zvakanyanya mumachira, ingi, fiber, dyeing, papermaking, cosmetics, mishonga yekuuraya zvipembenene, zvicherwa Kugadziriswa kwechigadzirwa, kudzoreredza mafuta uye maindasitiri emishonga.
zvakasiyana solubility
Hydroxypropyl methylcellulose: inenge isingawaniki mune absolute ethanol, ether, acetone;soluble mumvura yakajeka kana zvishoma ine makore colloidal solution mumvura inotonhora.
Hydroxyethyl cellulose (HEC): Inogona kugadzirira mhinduro mumhando dzakasiyana dze viscosity, uye ine yakanaka-kunyungudutsa munyu zvivakwa zve electrolytes.
