EipponCell HPMC YB 515M, oo si gaar ah loogu talagalay codsiyada koollada caadiga ah, waxay leedahay sifooyinka soo socda:
Marka budada cinjirka ah iyo cellulose ether HPMC ay ku jiraan hoobiye qoyan, budada RDP waxay soo bandhigaysaa tamar adag oo ku xiran sheyga fuuq-celinta sibidhka, halka ether-ka cellulose uu ugu horreyn saameyn ku yeesho dareeraha interstitial, oo saameeya viscosity iyo waqti go'an ee hoobiye.
Budada RDP waxay muujinaysaa ku-xidhnaanta la xoojiyey ee alaabta fuuq-celinta sibidhka, halka ether-ka cellulose ay ugu horreyntii saamayso dareeraha interstitial, saameynaya viscosity hoobiye iyo wakhti go'an.
Wada noolaanshaha budada cinjirka ah iyo cellulosic ether HPMC ee hoobiye qoyan waxay saameeyaan sifooyinka hoobiye, budada RDP oo leh tamar weyn oo isku xiran iyo eter cellulosic oo saameeya viscosity iyo dejinta waqti iyada oo loo marayo joogitaanka dareeraha interstitial.
Cellulose ether ee hoobiye ma aha oo kaliya inay bixiso sifooyin faa'iido leh, laakiin sidoo kale waxay dib u dhigtaa dhaqdhaqaaqa fuuq-celinta ee sibidhka iyada oo la isku dhejiyo badeecada fuuq-baxa halkii laga heli lahaa wajiga macdanta asalka ah.Saamayntan dib-u-dhaca waxaa loo aaneynayaa dhaqdhaqaaqa hoos u dhaca ions ee xalka daloolka sababtoo ah viscosity kordhay oo ay sababtay ether cellulose.
Joogitaanka ether cellulose ee nidaamyada sibidhka waxay dib u dhigtaa kinetics fuuq-celinta iyada oo la isku dhejiyo badeecada fuuq-baxa halkii laga heli lahaa marxaladda macdanta asalka ah, iyada oo sidoo kale kordhinaysa viscosity ee xalka daloolka, taas oo yaraynaysa dhaqdhaqaaqa ion iyo hoos u dhigista habka fuuq-celinta.
Saamaynta dib-u-dhaca Cellulose ether ee fuuq-celinta sibidhka waxa ugu horrayn lagu gaaraa iyada oo la isku dhejiyo badeecada fuuqbaxday iyo korodhka ku xiga ee viscosity ee xalka daloolka, taas oo caqabad ku ah dhaqdhaqaaqa ion iyo dib u dhigista dhaqdhaqaaqa guud ee fuuq-celinta.
