Kudai kuDilute HPMC?

Duliution yeHPMC (hydroxyprupyl methylcellose) inowanzo kugadzirisa yaro yekukoshesa kuti ienderane nezvakaringana application zvinodiwa. HPMC iri polymer yemvura yakawedzera kushandiswa zvakanyanya mumishonga yemishonga, kuvaka, chikafu uye maindasitiri ezvekudya.

(1) Kugadzirira
Sarudza iyo chaiyo HPMC akasiyana-siyana:

HPMC ine akasiyana viscooki uye solub risi. Kusarudza mhando dzakakodzera dzinogona kuona kuti mhinduro yakadonha inosangana nezvinodiwa zvekushandisa.
Gadzirira zvishandiso nezvishandiso:

HPMC poda
Mvura yakadzingwa kana mvura yakaderera
Magnetic anokurudzira kana manyoro anokurudzira
Kuyera maturusi akadai sekuyera cylinders uye kupunyuka makapu
Midziyo yakakodzera, yakadai segirazi mabhodhoro kana mapurasitiki emabhodhoro.

(2) Matanho Diki
Kuyera HPMC poda:

Zvinoenderana nekuvharirwa kuti kuve kwakanyudzwa, kuremera zvakaringana huwandu hunodiwa hweHPMC poda. Kazhinji, iyo yuniti yekuvhara ndeye uremu muzana (W / w%), yakadai se1%, 2%, nezvimwe.
Wedzera mvura:

Dururira huwandu hwakakodzera hwehuwandu hwakadzikira kana hwakaomeswa mvura mumudziyo. Kuwanda kwemvura kunofanirwa kutsanangurwa zvichienderana nezvinodiwa zvekupedzisira zvemhinduro yekupedzisira.
Kuwedzera HPMC poda:

Wedzera iyo yakayerwa HPMC inopisa zvakashata mumvura.

Kumutsa uye kupera simba:

Shandisa mhepo yemagineti kana mhanya yemanyoro kumutsa mhinduro. Kukurudzira kunogona kubatsira iyo HPMC Powder inodonha nekukurumidza uye zvakanyanya. Iyo yekumhanyisa kumhanya uye nguva inoda kugadziridzwa zvinoenderana nemhando uye kusunganidzwa kweHPMC. Kazhinji, iyo nguva yakakurudzirwa inosimudzira ndeye maminitsi makumi matatu kusvika maawa akati wandei.

Kumira uye Degassing:

Mushure mekukurudzira, regai mhinduro inomira kwenguva yakati, kazhinji 1 awa kusvika maawa makumi maviri nemana. Izvi zvinobvumira mabhuru mumhinduro yekukwira uye nekunyangarika, ichiratidza kufanana kwemhinduro.

(3) Kuchera

Kumhanyisa kumhanya uye nguva:

Iyo yekumhanyisa uye inguva yekukurudzira yeHPMC Dissolution inokanganiswa neyevisiko yayo uye tembiricha yemvura. Kazhinji kutaura, yakakwira viscosity hpmc inoda nguva refu inomutsa nguva.

Tembiricha yemvura:

Uchishandisa mvura inodziya (yakadai se40 ° C-60 ° C) inogona kukurudzira kupaza kweHPMC, asi chenjera kuti usashandise yakanyanya kupisa tembiricha kuti udzivise zvivakwa zveHPMC.

Kudzivirira Agglomeration:

Paunenge uchiwedzera HPMC poda, edza kudzivirira kuunganidzirwa. Iwe unogona kutanga kusanganisa iyo HPMC Powder ine madiki emvura mune slurry, uyezve zvishoma nezvishoma zviwedzere kumvura yasara kuti uderedze yakakura.
Kuchengetedza:

Mhinduro yeHPMC yakaderedzwa inofanira kuchengetwa mumudziyo wakachena, wakasungwa kuti udzivise kunyorova kana kusvibiswa. Mamiriro ekuchengetedza anofanirwa kugadziriswa zvinoenderana nezvinodiwa zvinodikanwa uye mamiriro ezvinhu epamhepo eHPMC.
Kuchengetedza:

Munguva yekuvhiya, yakakodzera yekudzivirira yemunhu se magurovhosi uye masks inofanira kupfekwa kuti isaswededza kusvika padhuze neHPMC poda uye mhinduro yakaomeswa.

Kuburikidza nematanho ari pamusoro apa, iwe unogona kuseta hpmc sezvinodiwa kuti uve nechokwadi chekushanda kwayo uye kugadzikana mune dzakasiyana zvikumbiro. Imwe neimwe mamiriro ekunyorera anogona kunge aine zvidzidzo zvakasiyana, saka zvakakosha kuti unzwisise uye kutevedzera zvakananga zviitiko zvekushandisa uye zvinodiwa.
