EipponCell HPMC YB 515M, e etselitsoeng ka ho khetheha lisebelisoa tse tloaelehileng tsa sekhomaretsi sa lithaele, e na le thepa e latelang:
Ha latex powder le cellulose ether HPMC li le teng ka seretse se metsi, phofo ea RDP e bonts'a matla a matla a tlamang ka sehlahisoa sa samente sa hydration, athe cellulose ether e ama haholo-holo mokelikeli oa interstitial, o amang viscosity le nako e behiloeng ea seretse.
RDP phofo e bonts'a ho khomarela lihlahisoa tsa samente tsa hydration, ha cellulose ether e ama haholo-holo interstitial fluid, e amang viscosity ea seretse le nako e behiloeng.
Ho ba teng ha latex powder le cellulosic ether HPMC ka seretse se metsi ho ama thepa ea seretse, e nang le phofo ea RDP e nang le matla a maholo a tlamang le cellulosic ether e amang viscosity le ho beha nako ka ho ba teng ha eona ka har'a mokelikeli oa interstitial.
Cellulose ether ka har'a seretse ha e fane feela ka thepa e molemo, empa hape e liehisa matla a hydration ea samente ka ho bapatsa sehlahisoa sa hydrated ho e-na le mohato oa pele oa liminerale.Phello ena ea ho lieha e bakoa ke ho tsamaea ho fokotsehileng ha li-ion ka tharollo ea pore ka lebaka la ho eketseha ha viscosity e bakoang ke cellulose ether.
Ho ba teng ha cellulose ether lits'ebetsong tsa samente ho sitisa hydration kinetics ka ho bapatsa sehlahisoa se nang le hydrate ho e-na le karolo ea pele ea liminerale, ha e ntse e eketsa viscosity ea tharollo ea pore, kahoo e fokotsa ho tsamaea ha ion le ho fokotsa ts'ebetso ea hydration.
Phello ea ho fokotseha ha cellulose ether ho hydration ea samente e finyelloa haholo-holo ka ho ikemela ha eona sehlahisoa sa hydrated le keketseho e latelang ea viscosity ea tharollo ea pore, e sitisang ho tsamaea ha ion le ho liehisa matla a hydration ka kakaretso.
