Tembiricha iyo iyo HPMC inodonha inotorawo basa rakakosha. HPMC inodonha yakanakisa mumvura inodziya, kunyanya pakati pe80-90 degrees celsius. Nekudaro, zvinofanirwa kucherechedzwa kuti tembiricha haifanire kunge yakanyanya kukwirisa, kana zvisina kudaro iyo HPMC ichatenderwa uye yakasvibiswa, ichikonzera kuderera kwemisangano uye kuita zvakanaka. Naizvozvo, zvakakosha kuti udzore nokungwarira tembiricha yeiyo solvent kuti ive nechokwadi chekuenderana uye kuita zvakaringana.
4. Sanganisa uye kumutsa
Kusanganisa uye kusanzwisisika kwakakosha kuti uve nechokwadi chekupaza zvakanaka kweHPMC. Kunyatso kusanganisa uye kushungurudzika kuchabatsira kuputsa iyo HPMC zvikamu uye gadzira mhinduro yehukama uye inowirirana. Naizvozvo, zvakakosha kuti ushandise nzira dzakakodzera kusanganisa, dzakadai sevanovhenganiswa nehombe-dzinobatsira, dzinobatsira kuwedzera masimba uye mhirizhonga mumhinduro.
5. Kusvina kweHPMC Solution
Iko kushungurudzika kweHPMC mumhinduro chinhu chakakosha kufunga kana zvichidzika hpmc. Kana iyo HPMC yekuvhara yakanyanya, inogona kukonzera mabwe kana agglomicierates kuti iite mhinduro, ichiita kuti zviome kuwana mhinduro yunifomu. Kune rimwe divi, kana kusangana kwakanyanya, kunogona kuguma nemhinduro iyo yakanyanya kuderera uye haina kuita zvakanaka.
mumhedziso
HPMC chinhu chose chose uye chakawandisa polymer ine huwandu hwakawanda hwekushandisa mumaindasitiri akadai sekuvaka, mishonga uye chikafu. Kuvhiringidzika kweHPMC kunogona kuita maitiro, uye zvakakosha kuti utarise nezvezvinhu zvakadai sekuchena, giredhi, solvent, tembiricha, kusanganisa, uye kusanganisa kweHPMC solution. Kubudirira kupaza uye mhedzisiro yaunoda kunogona kuwanikwa nekutevera mirairo yemugadziri uye nekunyatso kudzora zvinhu izvi.
