E le e 'ngoe ea metsoako ea bohlokoa ea cellulose ether ka seretse se omeletseng sa phofo, hydroxypropyl methylcellulose e na le mesebetsi e mengata ka seretse. Karolo ea bohlokoa ka ho fetisisa ea hydroxypropyl methylcellulose seretseng sa samente ke ho boloka metsi le ho teteana. Ho feta moo, ka lebaka la tšebelisano ea eona le tsamaiso ea samente, e ka boela ea phetha karolo e thusang ho kenya moea, ho fokotsa maemo, le ho ntlafatsa matla a maqhama a thata. phello.
Ts'ebetso ea bohlokoa ka ho fetisisa ea hydroxypropyl methylcellulose seretseng ke ho boloka metsi. Joalo ka motsoako oa cellulose ether ka seretseng, hydroxypropyl methylcellulose e ka sebelisoa hoo e batlang e le lihlahisoa tsohle tsa seretse, haholo-holo ka lebaka la ho boloka metsi. Ka kakaretso, ho boloka metsi a hydroxypropyl methylcellulose ho amana le viscosity ea eona, tekanyo ea ho fetola le boholo ba likaroloana.
Hydroxypropyl methylcellulose e sebelisoa e le motenya, 'me phello ea eona e teteaneng e amana le tekanyo ea ho fetola, boholo ba likaroloana, viscosity le tekanyo ea phetoho ea hydroxypropyl methylcellulose. Ha re bua ka kakaretso, ha tekanyo ea ho nkela sebaka le viscosity ea cellulose ether e le holimo, 'me likaroloana tse nyane, ho hlakile haholoanyane phello e teteaneng.
Ho hydroxypropyl methylcellulose, ho kenngoa ha lihlopha tsa methoxy ho fokotsa matla a holim'a metsi a metsi a nang le hydroxypropyl methylcellulose, e le hore hydroxypropyl methylcellulose e be le phello ea ho kenya moea holim'a seretse sa samente. Hlahisa li-bubble tsa moea tse nepahetseng seretseng, ka lebaka la "phello ea bolo" ea li-bubble tsa moea,
Ts'ebetso ea kaho ea seretse e ntlafatsoa, 'me ka nako e ts'oanang, ho kenngoa ha li-bubble tsa moea ho eketsa sekhahla sa tlhahiso ea seretse. Ha e le hantle, tekanyo ea ho kenngoa ha moea e hloka ho laoloa. Ho kenella haholo moeeng ho tla ba le tšusumetso e mpe ho matla a seretse.
Hydroxypropyl methylcellulose e tla liehisa ts'ebetso ea ho beha samente, ka hona e liehe ho beha le ho thatafatsa ts'ebetso ea samente, le ho lelefatsa nako ea ho bula seretse ka nepo, empa phello ena ha e ntle bakeng sa seretse libakeng tse batang.
Joalo ka ntho e telele ea ketane ea polymer, hydroxypropyl methylcellulose e ka ntlafatsa ts'ebetso ea tlamahano le substrate kamora ho eketsoa ho sistimi ea samente tlasa motheo oa ho boloka mongobo ka botlalo ho slurry.
Ho akaretsa, tšebetso eaHPMCka seretseng haholo-holo e kenyelletsa: ho boloka metsi, ho teteana, ho lelefatsa nako ea ho beha, ho kenya moea le ho ntlafatsa matla a maqhama a thata, joalo-joalo.
