Kushandiswa kweEthylcellulose Coating kune Hydrophilic Matrices

Ethylcellulose (EC) inowanzoshandiswa polima muindasitiri yemishonga yekuputira maumbirwo emishonga.Iyo hydrophobic polymer iyo inogona kupa chipingamupinyi chekudzivirira mushonga kubva kunyoro, chiedza, uye zvimwe zvakatipoteredza zvinhu.EC coatings inogonawo kugadzirisa kuburitswa kwemushonga kubva mukuumbwa, sekunge nekupa yakaramba yakaburitswa mbiri.

Hydrophilic matrices imhando yekugadzirwa kwemishonga ine mvura-inonyungudika kana mvura-inoputika mapolymers, akadai sehydroxypropyl methylcellulose (HPMC).Aya matrices anogona kushandiswa kupa kuburitswa kwemushonga kunodzorwa, asi anogona kutapukirwa nekutora mvura uye kunotevera kuburitswa kwezvinodhaka.Kuti ukunde kuganhurirwa uku, machira eEC anogona kuiswa pamusoro peiyo hydrophilic matrix kuti iite danda rekudzivirira.

Iko kushandiswa kweEC coatings kune hydrophilic matrices kunogona kupa akati wandei mabhenefiti.Chekutanga, iyo EC coating inogona kuita senge inodzivirira hunyoro kuchengetedza iyo hydrophilic matrix kubva pakutora mvura uye kunotevera kuburitswa kwezvinodhaka.Chechipiri, iyo EC coating inogona kugadzirisa kuburitswa kwemushonga kubva kune iyo hydrophilic matrix, senge nekupa yakaramba yakaburitswa mbiri.Pakupedzisira, iyo EC coating inogona kuvandudza kugadzikana kwemuviri kwekuumbwa, senge nekudzivirira agglomeration kana kunamatira kwezvimedu.

Iko kushandiswa kweEC coatings kune hydrophilic matrices kunogona kuwanikwa uchishandisa akasiyana nzira dzekupfekedza, senge kupfapfaidza coating, fluid mubhedha coating, kana pan coating.Sarudzo yehunyanzvi hwekupfekedza inoenderana nezvinhu zvakaita semagadzirirwo ezvivakwa, ukobvu hwehuputi hunodiwa, uye chiyero chekugadzirwa.

Muchidimbu, kushandiswa kweEC coatings kune hydrophilic matrices inzira yakajairika muindasitiri yemishonga kugadzirisa kuburitswa kweprofile uye kugadzirisa kugadzikana kwekuumbwa kwezvinodhaka.
