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 lebelo la ho beha le ho thatafala ha samente, le ho lelefatsa nako ea ho bula seretse ka nepo, empa phello ena ha e ntle bakeng sa seretse libakeng tse batang.
