Ts'ebeliso ea EipponCell HPMC YB400 e na le thepa e latelang ho lisebelisoa tsa fatše tsa ho iteka :
1.Ho boloka metsi
Ho bolokoa ha metsi a seretse se sa tsoa tsoakoa sa samente ke ntlha ea bohlokoa e amang botsitso ba likarolo tsa eona tsa ka hare.HPMC YB400 ke tlatsetso e sebetsang e sebelisetsoang ho boloka mongobo ka har'a seretse nako e telele, e nolofalletsang thepa ea gel ho arabela ka botlalo.Lihlahisoa tsa HPMC YB400 tse nang le viscosity ea ho pota 400mpa.s li sebelisoa hangata lits'ebetsong tsa seretse sa ho ikemela.Keketso ena e ntlafatsa ts'ebetso ea seretse mme e eketsa ho kopana ha eona ka kakaretso.Ka ho ntlafatsa matla a ho boloka metsi a seretse se ikemetseng, HPMC YB400 e tiisa hore seretse se boloka botsitso ba sona bo lakatsehang, se nolofalletsa ho sebelisa le ho lebisa liphellong tse molemo mererong ea kaho.
2. Mokelikeli
Hydroxypropyl methylcellulose (HPMC) YB400 ke ntlha ea bohlokoa ho khethollang ho bolokoa ha metsi, ho ts'oara, le ts'ebetso ea kaho ea seretse se ikemetseng.Bakeng sa lits'ebetso tsa seretse sa ho ikemela, fluidity ke sesupo sa bohlokoa se khethollang boleng ba ts'ebetso ea ho ikemela.Ka ho fetola palo ea HPMC YB400 e ekelitsoeng, metsi a seretse a ka laoloa ntle le ho ama sebopeho sa eona se tloaelehileng.Leha ho le joalo, ho bohlokoa ho netefatsa hore litekanyetso tsa HPMC li ka har'a sebaka se lekaneng ho qoba litlamorao tse mpe ts'ebetsong ea seretse.Ho laola ka nepo palo ea HPMC YB400 e kenyellelitsoeng ho ka thusa ho netefatsa botsitso bo lakatsehang le metsi a seretse sa ho ikemela, se lebisang ho litholoana tse ntle mererong ea kaho.
3. Nako ea ho koala
Ho eketsoa ha EipponCell HPMC YB400 ho seretse ho ka baka tieho ea nako ea ho beha motsoako.Ha palo ea HPMC YB400 e ntse e eketseha, phello ena e ba e hlakileng haholoanyane.Sena se bakoa ke ho thehoa ha lera le rarahaneng la filimi, le ka ba le tšusumetso e kholo ho hydration ea pele ea samente 'me ea lebisa ho fokotseha ho hoholo ha nako ea ho beha.HPMC YB400 e ka baka tšusumetso e fokolang holim'a seretse, 'me tekanyo ea phello e amana haufi-ufi le litekanyetso tsa eona.
4.Flexural matla le compressive matla
Ho eketsoa ha HPMC YB400 ho thepa e thehiloeng ho samente ho ka fella ka ho fokotseha ha matla a khatello le a feto-fetohang a seretse ha litekanyetso li ntse li eketseha.Matla ke index ea bohlokoa ea tlhahlobo bakeng sa phello ea pholiso ea lisebelisoa tse joalo.
5.Bond matla
Ts'ebetso ea tlamahano ea seretse e angoa haholo ke tlatsetso ea HPMC YB400.HPMC e etsa filimi ea polymer e sebetsang e le tiiso pakeng tsa tsamaiso ea mokelikeli oa metsi le likaroloana tsa samente tsa hydration, ho ntlafatsa ho boloka metsi le ho sebetsa ha seretse.Ha palo e loketseng ea HPMC YB400 e eketsoa, polasetiki le ho feto-fetoha ha seretse lia ntlafatsoa, e leng ho fokotsang ho tiea ha sebaka sa phetoho lipakeng tsa seretse le sebopeho sa substrate.Sena, ka lehlakoreng le leng, se fokotsa bokhoni ba ho thella lipakeng tsa li-interfaces mme se lebisa ho matla a matla a maqhama.Phello ea ho tiisa ea HPMC YB400 e boetse e thusa ho fokotsa tahlehelo ea metsi le ho ntlafatsa ts'ebetso ea hydration nakong ea ho beha le ho phekola, ho fella ka thepa e teteaneng le e tšoarellang ho feta ea samente.Keketso ea HPMC YB400 ha e ntlafatse ts'ebetso ea bonding ea seretse feela empa hape e ntlafatsa ts'ebetso ea eona le ho tšoarella ha eona.
