Hydroxypropyl methylcellulose ke e 'ngoe ea li-additives tsa bohlokoa tsa cellulose ether seretseng se omeletseng mme e na le mesebetsi e mengata seretseng.Mesebetsi ea mantlha 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 ea ho kenya moea, ho fokotsa maemo, le ho ntlafatsa matla a ho tiisa maqhama.Tšusumetso.
Ts'ebetso ea bohlokoa ka ho fetisisa ea hydroxypropyl methylcellulose seretseng ke ho boloka metsi.Joalo ka motsoako oa cellulose ether seretseng, hydroxypropyl methylcellulose e ka sebelisoa hoo e batlang e le lihlahisoa tsohle tsa seretse, haholo-holo ka lebaka la thepa ea eona ea 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 phalliso le viscosity ea cellulose ether e phahame, boholo ba karoloana e nyane le phello e hlakileng haholoanyane.
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 palo e loketseng ea lipululana ka seretseng.Ka lebaka la "phello ea bolo" ea li-bubble,
Ts'ebetso ea kaho ea seretse e ntlafalitsoe, ha ho kenngoa ha li-bubble tsa moea ho eketsa chai ea seretse.Ha e le hantle, tekanyo ea moea o kentsoeng e hloka ho laoloa.Ha moea o mongata o kenngoa, o ka ama matla a seretse hampe.
Hydroxypropyl methylcellulose e tla liehisa ts'ebetso ea ho beha samente, e liehe ho beha le ho thatafatsa ts'ebetso ea samente, le ho eketsa nako ea ho bula seretse ka nepo.Leha ho le joalo, phello ena ha e ntle bakeng sa seretse libakeng tse batang.
Joaloka ntho e telele ea ketane ea polymer, hydroxypropyl methylcellulose e ka ntlafatsa ts'ebetso ea ho tlamahane ka thepa ea motheo ha e ntse e boloka ka botlalo mongobo oa slurry ha e kenngoa tsamaisong ea samente.
Thepa ea mantlha ea HPMC ka seretse e kenyelletsa: ho boloka metsi, ho tenya, ho eketsa nako ea ho beha, ho kenella moeeng, ho ntlafatsa matla a bond, joalo-joalo.
