IHydroxypropyl methylcellulose isetyenziswa kakhulu kushishino lokwakha. Namhlanje, ndiza kwazisa indlela yokuchithwa kwe-hydroxypropyl methylcellulose kunye nendlela yokugweba umgangatho we-hydroxypropyl methylcellulose.
Indlela yokunyibilikisa i-hydroxypropyl methylcellulose:
Zonke iimodeli zingongezwa kwizinto eziphathekayo ngokuxuba okomileyo;
Xa kufuneka ifakwe ngokuthe ngqo kwisisombululo se-aqueous yeqondo lokushisa eliqhelekileyo, kungcono ukusebenzisa uhlobo lokusasazwa kwamanzi abandayo, kwaye lunokuqina ngaphakathi kwemizuzu eyi-10-90 emva kokongeza;
Emva kokuphazamisa kunye nokusabalalisa ngamanzi ashushu kuhlobo oluqhelekileyo, yongeza amanzi abandayo kwaye ugxobhoze ukuze uchithe;
Ukuba kukho i-agglomeration kunye ne-coating ngexesha lokuchithwa, kubangelwa ukuvuselela okunganeleyo okanye ukongezwa ngokuthe ngqo kwamanzi abandayo kwiiprofayili eziqhelekileyo. Ngeli xesha, kufuneka ixutywe ngokukhawuleza;
Ukuba ama-bubbles aveliswa ngexesha lokuchithwa, banokushiywa ukuba bame iiyure ezingama-2-12 (zinqunywe ngokuhambelana nesisombululo) okanye zisuswe ngokukhutshwa, ukunyanzeliswa, njl., kunye nemali efanelekileyo ye-defoamer nayo inokongezwa.
Ungawugweba njani umgangatho we-hydroxypropyl methylcellulose ngokulula nangokucacileyo
Ubumhlophe: Ngokobumhlophe, akunakwenzeka ukugqiba ukuba i-HPMC ingasetyenziswa ngokuqhelekileyo, kwaye ukuba i-agent emhlophe yongezwa kwinkqubo yokuvelisa, iya kuchaphazela nomgangatho wayo. Nangona kunjalo, iimveliso ezinobumhlophe obuhle zilungile.
Ukulunga: I-HPMC iqhelekile yi-80 mesh, i-100 mesh, i-120 mesh, i-finere icolile ingcono.
Ugqithiso: faka i-HPMC emanzini ukwenza i-colloid ecacileyo, kwaye ijonge ukuhanjiswa kwayo. Okukhona ukuhanjiswa okukhulu, kokukhona kuncinci okunganyibilikiyo emanzini. Ngokubanzi, ugqithiso lungcono kwiireactors ezithe nkqo nakwireactors ezithe tyaba. Kubi kakhulu kwi-reactor ethe nkqo, kodwa ayinakucacisa ukuba umgangatho wemveliso eveliswe yi-reactor ethe nkqo ungcono kunaleyo yereactor ethe tye.
Ubunzima obuthile: Ngokuqhelekileyo, ngenxa yomxholo ophezulu we-hydroxypropyl, umphumo wokugcina amanzi ulungile.
