Hydroxypropyl methylcellulose inoshandiswa zvakanyanya muindasitiri yekuvaka. Nhasi, ini ndichasuma nzira yekumisa yehydroxypropyl methylcellulose uye maitiro ekutonga kunaka kwehydroxypropyl methylcellulose.
Nzira yekunyungudutsa hydroxypropyl methylcellulose:
Mienzaniso yose inogona kuwedzerwa kune zvinyorwa nekusanganiswa kwakaoma;
Kana ichida kuwedzerwa zvakananga kune yakajairika tembiricha aqueous solution, zviri nani kushandisa mvura inotonhora yekuparadzira mhando, uye inogona kukora mukati me10-90 maminetsi mushure mekuwedzera;
Mushure mekusimudzira uye kuparadzira nemvura inopisa yemhando yakajairika, wedzera mvura inotonhora uye simbisa kuti iparadze;
Kana paine agglomeration uye coating panguva yekunyungudika, inokonzereswa nekusakwana kubvongodza kana kuwedzera kwakananga kwemvura inotonhora kune akajairwa profiles. Panguva ino, inofanira kumutswa nokukurumidza;
Kana mabhubhu akagadzirwa panguva yekuparara, anogona kusiiwa kuti amire kwemaawa 2-12 (akatemerwa maererano nekuenderana kwemhinduro) kana kubviswa nekubuda, kudzvanywa, nezvimwewo, uye huwandu hwakakodzera hwe defoamer hunogonawo kuwedzerwa.
Maitiro ekutonga mhando yehydroxypropyl methylcellulose zviri nyore uye intuitively
Huchena: Zvinoenderana nekuchena, hazvigoneke kuona kuti HPMC inogona kushandiswa zvakajairwa, uye kana chena maajenti akawedzerwa mukugadzira maitiro, zvinokanganisawo kunaka kwayo. Nekudaro, zvigadzirwa zvine kuchena kwakanaka zvinonyanya kunaka.
Fineness: HPMC inowanzoita 80 mesh, 100 mesh, 120 mesh, iyo yakatsetseka ndiyo yakanyanya kunaka.
Transmittance: isa HPMC mumvura kuti iite yakajeka colloid, uye tarisa kutapurirana kwayo. Iyo yakakura iyo transmittance, zvishoma zvisinganyunguriki zvinhu mumvura. Kazhinji, iyo transmittance iri nani mune vertical reactors uye horizontal reactor. Izvo zvakanyanya kuipa mureactor yakatwasuka, asi haigone kutsanangura kuti kunaka kwechigadzirwa chinogadzirwa neiyo vertical reactor iri nani pane iyo yakachinjika reactor.
Chaiyo giravhiti: Kazhinji kutaura, nekuda kweiyo yakakwira hydroxypropyl yemukati, iyo yekuchengeta mvura mhedzisiro yakanaka.
