IHydroxypropyl methylcellulose isetshenziswa kabanzi embonini yezokwakha.Namuhla, ngizokwethula indlela yokuchithwa kwe-hydroxypropyl methylcellulose kanye nendlela yokwahlulela ikhwalithi ye-hydroxypropyl methylcellulose.
Indlela yokuncibilikisa i-hydroxypropyl methylcellulose:
Wonke amamodeli angangezwa kundaba ngokuxuba okomile;
Uma idinga ukungezwa ngqo kwisisombululo esinamanzi esishisayo esivamile, kungcono ukusebenzisa uhlobo lokuhlakazeka kwamanzi abandayo, futhi lungaqina phakathi kwemizuzu engu-10-90 ngemva kokwengeza;
Ngemva kokuhlanganisa nokusabalalisa ngamanzi ashisayo ohlobo oluvamile, engeza amanzi abandayo bese ugoqa ukuze uwahlakaze;
Uma kukhona i-agglomeration kanye ne-coating ngesikhathi sokuchithwa, kubangelwa ukugoqa okunganele noma ukungezwa okuqondile kwamanzi abandayo kumaphrofayili ajwayelekile.Ngalesi sikhathi, kufanele ishukunyiswe ngokushesha;
Uma ama-bubbles ekhiqizwa ngesikhathi sokuchithwa, angashiywa ukuze ame amahora angu-2-12 (anqunywe ngokuvumelana nokuvumelana kwesixazululo) noma asuswe ngokuphuma, ukucindezela, njll., futhi inani elifanele le-defoamer nalo lingangezwa.
Indlela yokwahlulela ikhwalithi ye-hydroxypropyl methylcellulose kalula nangendlela enembile
Ubumhlophe: Ngokusho kobumhlophe, akunakwenzeka ukunquma ukuthi i-HPMC ingasetshenziswa ngokujwayelekile, futhi uma ama-ejenti amhlophe engezwa enqubweni yokukhiqiza, izophinde ithinte ikhwalithi yayo.Nokho, imikhiqizo enobumhlophe obuhle ngokuvamile mihle.
Ukulunga: I-HPMC ivamise ukuba yi-80 mesh, 100 mesh, 120 mesh, inciphe kakhulu iba ngcono.
I-Transmittance: faka i-HPMC emanzini ukuze yakhe i-colloid esobala, futhi ubheke ukudluliselwa kwayo.Uma kukhulu ukudluliswa, izinto ezincane ezingancibiliki emanzini.Ngokuvamile, ukudluliswa kwe-transmitta kungcono kuma-reactors aqondile nama-reactor avundlile.Kubi kakhulu kureactor eqondile, kodwa ayikwazi ukuchaza ukuthi ikhwalithi yomkhiqizo okhiqizwe i-reactor eqondile ingcono kunaleyo ye-reactor evundlile.
Amandla adonsela phansi athile: Ngokuvamile, ngenxa yokuqukethwe okuphezulu kwe-hydroxypropyl, umphumela wokugcina amanzi muhle.
