Hydroxyethyl Cellulose (HEC) i polymer inonyungudika nemvura inowanzoshandiswa seyakakora, emulsifier, stabilizer, nezvimwe.
Hydroxyethyl Cellulose Dissolution Matanho
Gadzirira zvinhu uye midziyo:
Hydroxyethyl Cellulose powder
Solvent (kazhinji mvura)
Kukurudzira mudziyo (senge mechanical stirrer)
Maturusi ekuyeresa (kuyeresa silinda, chiyero, nezvimwewo)
Container
Kupisa iyo solvent:
Kuti ikurumidze kunyungudutswa, iyo inonyungudutsa inogona kupisa zvakafanira, asi kazhinji haifanire kudarika 50 ° C kudzivirira kukanganisa kwemafuta. Tembiricha yemvura iri pakati pe30°C ne50°C ndiyo yakanaka.
Zvishoma nezvishoma wedzera HEC poda:
Paridza zvishoma nezvishoma HEC poda mumvura inopisa. Kuti udzivise kusanganisa, wedzera kuburikidza nesefa kana kuti zvishoma nezvishoma umwase. Iva nechokwadi chokuti HEC powder yakapararira zvakafanana panguva yekukurudzira.
Ramba uchimutsa:
Munguva yekukurudzira, ramba uchiwedzera zvishoma nezvishoma HEC poda kuti uone kuti hupfu hwakapararira mumvura. Iyo yekumhanyisa kumhanya haifanirwe kunge ichimhanya zvakanyanya kudzivirira mabhuru uye agglomeration. Kukurungamisa kwepakati pepakati kunowanzokurudzirwa.
Kuparara kwakamira: Mushure mekupararira kwakakwana, zvinowanzodiwa kumira kwenguva (kazhinji maawa akawanda kana kupfuura) kubvumira HEC kuti iparadze zvachose uye iite sarudzo yakafanana. Nguva yekumira inobva pane molecular uremu hweHEC uye kusungirirwa kwemhinduro.
Kugadzirisa viscosity: Kana iyo viscosity ichida kugadziriswa, huwandu hweHEC hunogona kukwidziridzwa kana kudzikiswa zvakakodzera. Mukuwedzera, inogonawo kugadziriswa nekuwedzera electrolytes, kuchinja pH kukosha, nezvimwe.
Precautions pakuparara
Dzivisa agglomeration: Hydroxyethyl cellulose iri nyore kuita agglomerate, saka kana uchiwedzera hupfu, teerera zvakanyanya kuti umwase zvakaenzana. Sefa kana imwe mudziyo wekuparadzira unogona kushandiswa kubatsira kuparadzira zvakaenzana.
Kudzora tembiricha: Iyo tembiricha yekunyungudutsa haifanirwe kunge yakanyanya kukwirira, zvikasadaro inogona kukonzera kupisa kweHEC uye kukanganisa kushanda kwemhinduro. Kazhinji zvakakodzera kuzvidzora pakati pe30°C ne50°C.
Dzivirira mhepo kuti isapinda: Dzivisa kubvongodza nekukasira kudzivirira mweya kupinda mugadziro kuti uite mabubbles. Mabhuru anozokanganisa kufanana uye pachena kwemhinduro.
Sarudza iyo yakakodzera inosimudzira midziyo: Sarudza iyo yakakodzera inosimudzira midziyo inoenderana viscosity yemhinduro. Kune yakaderera-viscosity mhinduro, zvakajairwa zvinokurudzira zvinogona kushandiswa; nokuda kwe-high-viscosity solutions, mhepo yakasimba inogona kudiwa.
Kuchengeta nekuchengetedza:
Iyo yakanyungudika HEC mhinduro inofanira kuchengetwa mumudziyo wakavharwa kudzivirira unyoro kana kusvibiswa. Kana yakachengetwa kwenguva yakareba, dzivisa zuva rakananga uye nzvimbo yekushisa yakakwirira kuti uone kugadzikana kwemhinduro.
Matambudziko akajairika uye mhinduro
Uneven dissolution:
Kana kuparara kusina kuenzana kuchiitika, zvinogona kunge zvichikonzerwa nekuti hupfu hunosaswa nekukurumidza kana kubvongodzwa zvisina kukwana. Mhinduro ndeyekuvandudza kufanana kwekukurudzira, kuwedzera nguva yekukurudzira, kana kugadzirisa kukurumidza kwekuwedzera kwehupfu panguva yekukurudzira.
Bubble kugadzirwa:
Kana nhamba huru yemabhubhu ichionekwa mune mhinduro, mabhubhu anogona kuderedzwa nekudzikisa kukurumidza kumhanyisa kana kuita kuti imire kwenguva yakareba. Kune mabubbles akatoumba, degassing agent inogona kushandiswa kana ultrasonic treatment inogona kushandiswa kuvabvisa.
Solution viscosity yakawandisa kana yakaderera:
Kana mhinduro viscosity isingasviki zvinodiwa, inogona kudzorwa nekugadzirisa huwandu hweHEC. Uye zvakare, kugadzirisa iyo pH kukosha uye ionic simba remhinduro inogona zvakare kukanganisa viscosity.
Iwe unogona kunyatso nyungudutsa hydroxyethyl cellulose uye kuwana yunifomu uye yakagadzikana mhinduro. Kuziva nhanho dzekushanda dzakakwana uye dziviriro dzinogona kuwedzera mhedzisiro yehydroxyethyl cellulose mumashandisirwo akasiyana siyana.
