Hydroxypropyl methylcellulose, yomwe imadziwikanso kuti hypromellose ndi cellulose hydroxypropyl methyl ether, imapangidwa kuchokera ku cellulose ya thonje yoyera kwambiri ndipo imakhala ndi etherified mwapadera pansi pamikhalidwe yamchere.
kusiyana kwake:
makhalidwe osiyanasiyana
Hydroxypropyl methylcellulose: ufa kapena ma granules oyera kapena oyera, amitundu yosiyanasiyana yopanda ma ionic mu osakaniza a cellulose, mankhwalawa ndi semi-synthetic, osagwira viscoelastic polima.
Hydroxyethyl cellulose ndi yoyera kapena yachikasu, yopanda fungo, yopanda poizoni kapena ufa wolimba, zopangira zazikulu ndi alkali cellulose ndi ethylene oxide etherification, yomwe ndi yopanda ionic sungunuka cellulose ether.
Kugwiritsa ntchito ndikosiyana
M'makampani opaka utoto, hydroxypropyl methylcellulose imakhala yabwino kusungunuka m'madzi kapena zosungunulira organic monga thickener, dispersant ndi stabilizer.Polyvinyl kolorayidi amagwiritsidwa ntchito ngati chochotsa utoto poyimitsidwa polima pokonzekera polyvinyl chloride, yomwe imagwiritsidwa ntchito kwambiri pazikopa, zinthu zamapepala, kusunga zipatso ndi masamba, nsalu ndi mafakitale ena.
Hydroxypropyl methylcellulose: pafupifupi osasungunuka mu ethanol, ether, acetone;sungunuka mu njira yowonekera kapena turbid colloidal m'madzi ozizira, omwe amagwiritsidwa ntchito kwambiri popaka, inki, ulusi, utoto, kupanga mapepala, zodzoladzola, mankhwala ophera tizilombo, minerals processing, kubwezeretsa mafuta ndi mafakitale ogulitsa mankhwala.
kusungunuka kosiyanasiyana
Hydroxypropyl methylcellulose: pafupifupi osasungunuka mu ethanol, ether, acetone;sungunuka mu njira yomveka bwino kapena ya mitambo pang'ono ya colloidal m'madzi ozizira.
Hydroxyethyl cellulose (HEC): Imatha kukonza njira zopangira ma viscosity osiyanasiyana, ndipo imakhala ndi zinthu zabwino zosungunula mchere wama electrolyte.
