Vese HydroxyPropropyl methylcellose uye hydroxytl cellelose is cellulose, Ndeupi musiyano uripo pakati pezviviri?

01
HPMC uye Hec
HydroxyPropyl methylcellose (Hypromellose), anozivikanwawo seHyprollose, rudzi rwevasina-ionic cellulose yakasanganiswa ether. Icho semisynthetic, isingashande, viscoelastic polymer inowanzo shandiswa seyakajairwa muOphthalmology, kana seyenzi kana mota mumishonga yemuromo.
Hydroxethyl Cellulose (Hec), Chemical Fomula2) N, ine chepfu yero, isina kuchena Nekuti hec ine zvivakwa zvakanaka zvekuremerwa, zvichimanikidza, kupararira, kusungirirwa, kuchengetedzwa kwemanyoro uye kuchiva, pepa uye mimwe minda, makumi mana eminda, mesheni

mutsauko
Kunyangwe ese ari maviri cellulose, kune misiyano yakawanda pakati pezviviri izvi:
Hydroxyprusyl methylcellose uye hydroxythylcellose inosiyana mune zvivakwa, zvinoshandiswa, uye solubility.

1. Zvimiro zvakasiyana
HydroxyPropyl methylcellose: (HPMC) ine chena kana yakafanana chena fiber kana granuly fiber kana poda poda Icho chiSeMi-synthetic isiri-mupenyu viscoelastic polymer.
HydroxyTHETHELLELceLose: (HEC) ndeye chena kana yero, yekunhuhwirira uye isina musoro fiber kana poda yakasimba. Izvo zvinotsauswa neAlkaline cellulose uye ethylene oxide (kana chlorohydrin). Izvo ndezvevasina-ionic soluble cellulose ether.

2. Salumility yakasiyana
Hydroxyprusyl methylcellose: Pamwe zvisingawanzo muless ethanol, ether uye acetone. Yakajeka kana zvishoma makore mashoma colodal solution yakanyungudika mumvura inotonhora.
HydroxytHyl Cellulose: Iyo ine zvivakwa zvekuremedza, zvichimisa, kusunga, zvichikonzera, kupararira uye kunyorovesa. Inogona kugadzirira mhinduro mune dzakasiyana viscosity dzungudzo uye ine yakanakisa munyu solubility yemagetsi.
HydroxyPropyl methylcellose ane hunhu hwekukakavara kugona, kudzikisira kwemunyu, kudzikisira kwemvura, kudzikisira kwemvura, kuumbwa kwemafirimu ekuumba, kupararira uye kuwirirana.

Pane mutsauko zvakawanda pakati pezviviri, uye kubatsira kwavo muindasitiri zvakare kwakasiyana chaizvo.

HydroxyPropyl methylcellose inonyanya kushandiswa seanotenderera, inoparadzira uye stabilizer muindasitiri yekubatanidza, uye ine yakanaka solubility mumvura kana organic sol. Muindasitiri yekuvaka, inogona kushandiswa musi, Gypsum, Latex Putty, plaster, etces, kugadzirisa kupararira kwejecha uye nekuvandudza kwazvo kupurasitiki uye nekuchengetwa kwemvura.
HydroxytHyl Cellulose ine zvivakwa zvekuita zvakakora, zvichimisa, kusunga, zvichikonzera, kuparadzira uye kunyorovesa. Inogona kugadzirira mhinduro mune dzakasiyana viscosity dzungudzo uye ine yakanakisa munyu solubility yemagetsi. HydroxytHyl Cellulose ndiyo inoshanda yefirimu yaimbova, Thickifier, Thickener, Stabilizer uye inopararira muShampoos, kusimuka, kusava nehanya, magetsi uye cosmetics; Mukushambidza podeters pakati ndeye mhando yerudzi rwekudzoreredza mumiririri. HydroxytHyl Cellulose inodonha nekukurumidza pakudziya kwakanyanya, iyo inogona kukurumidza kugadzirwa kwekugadzira uye kugadzirisa maitiro ekugadzira. Chinhu chiri pachena chesarudzo chine hydroxyethyl cellelose ndeyekuti inogona kuvandudza kuseka uye kunonzwisisika kwemachira.
