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. Joaloka motsoako oa cellulose ether ka seretse, 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.
