IHydroxypropyl methylcelluloseinokuqina, ukubopha, ukusabalalisa, i-emulsifying, ifilimu-ifom, ukumisa, i-adsorbing, i-gelling, i-surface esebenzayo, igcina ukufuma kunye neempawu ze-colloid ezikhuselayo. Uluhlu lwezicelo lubanzi kakhulu.
Ukulunga
Ubunono be-hydroxypropyl methylcellulose buba ne-80 mesh kunye ne-100 mesh. Okukhona ukucoleka, ngokukhawuleza ukuchithwa, ukuthetha ngokubanzi, kungcono. Ngesiqhelo, iireactors ezithe nkqo zivelisa iimveliso ezibhityileyo kunereactors ezithe tyaba.
Ugqithiso
Nyibilikisa i-hydroxypropyl methylcellulose (HPMC) emanzini ukwenza ulwelo olungafihliyo. Jonga ukukhanya kwayo. Okukhona ukuhanjiswa kokukhanya, kungcono, kubonisa ukuba kukho izinto ezinganyibilikiyo kangako kuyo.
umlinganiselo
Ubungakanani obuphakathi bungcono. Ukuba ubunzima obuthile bukhulu kakhulu okanye buncinci kakhulu, inokuba sisiphumo solawulo olulambathayo ngexesha lenkqubo yemveliso.
Umphandle
I-hydroxypropyl methylcellulose ecocekileyo ibonakala i-fluffy kwaye inobuninzi obuncinci, ukusuka kwi-0.3-0.4g / ml; HPMC exutyiweyo ine fluidity engcono kwaye uziva enzima, nto leyo ngokucacileyo eyahlukileyo ukusuka imveliso yokwenene ngenkangeleko. Ukubonakala kweminye i-cellulose yenjongo ekhethekileyo ikwahluke kakhulu kwiinkcukacha eziqhelekileyo, kwaye iimveliso ezithile zihlalutywa ngokweenkcukacha.
isisombululo samanzi
Isisombululo esicocekileyo se-HPMC samanzi sicacile, ukuhanjiswa kokukhanya okuphezulu, izinga lokugcinwa kwamanzi ≥ 90%; Isisombululo se-aqueous HPMC esixutyiweyo sinesiphithiphithi, kwaye izinga lokugcinwa kwamanzi kunzima ukufikelela kwi-70%
I-BaiDu
Nangona ubumhlophe abunakumisela ukubaHPMCkulula ukuyisebenzisa, kwaye ukuba ii-agent ezimhlophe zongezwa ngexesha lenkqubo yokuvelisa, iya kuchaphazela umgangatho wayo. Nangona kunjalo, uninzi lweemveliso ezilungileyo zinobumhlophe obuhle.
