Hydroxypropyl methylcellulose isiri-ionic cellulose ether yakagadzirwa kubva kune yakasikwa polymer material cellulose kuburikidza nehurongwa hwemakemikari maitiro.Imhando yehupfu huchena husinganhuhwi, husina chepfu, hunoputika mumvura inotonhora uye hunonzi clear or little cloudy colloidal solution.Iine maitiro ekukora, kusunga, kuparadzira, emulsifying, firimu-kuumba, kumisa, adsorbing, gelling, pamusoro pekushanda, kuchengetedza unyoro nekudzivirira colloid.
Yakanakisa hydroxypropyl methylcellulose inogona kunyatsogadzirisa dambudziko rekuchengetedza mvura pasi pekupisa kwakanyanya.Mumwaka wekushisa kwakanyanya, kunyanya munzvimbo dzinopisa uye dzakaoma uye dzakatetepa-layer kuvaka padivi rezuva, yepamusoro-mhando HPMC hydroxypropyl methylcellulose inodiwa kuvandudza kuchengetwa kwemvura kweslurry.
Yepamusoro-mhando hydroxypropyl methylcellulose ine kunyanya kunaka kufanana.Mapoka ayo methoxy uye hydroxypropoxy akagovaniswa zvakaenzana pamwe chete ne cellulose molecular cheni, iyo inogona kuwedzera maatomu eokisijeni pa hydroxyl uye ether bond uye mubatanidzwa wemvura.Kugona kusanganisa uye kuumba hydrogen zvisungo zvinoshandura mvura yemahara kuita mvura yakasungwa, nekudaro zvinobudirira kudzora kubuda kwemvura kunokonzerwa nekupisa kwemamiriro ekunze uye kuwana yakakwirira yekuchengetedza mvura.
