Hydroxyethyl Cellulose (HEC) ipolymer inonyungudika mumvura inowanzo shandiswa se thickener, emulsifier, stabilizer, nezvimwewo.
Matanho Ekunyunguduka kweHydroxyethyl Cellulose
Gadzirira zvinhu nemidziyo:
Upfu hweHydroxyethyl Cellulose
Chinonyungudutsa (kazhinji mvura)
Mudziyo wekukurunga (semuchina wekukurunga)
Zvishandiso zvekuyera (kuyera sirinda, chiyero, nezvimwewo)
mudziyo
Kupisa solvent:
Kuti kukurumidzise kunyungudika, chinhu chinonyungudutsa chinogona kupiswa zvakakodzera, asi kazhinji hachifanirwe kudarika 50°C kudzivirira kuparara kwekupisa. Tembiricha yemvura iri pakati pe30°C ne50°C ndiyo yakanaka.
Wedzera zvishoma nezvishoma HEC powder:
Dururirai upfu hweHEC zvishoma nezvishoma mumvura inopisa. Kuti musaungane, huisei nesefa kana kuti muhudururirei zvishoma nezvishoma. Ita shuwa kuti upfu hweHEC hwakapararira zvakaenzana panguva yekukurunga.
Ramba uchikurunga:
Munguva yekukurunga, ramba uchiisa HEC powder zvishoma nezvishoma kuti uve nechokwadi chekuti upfu hwapararira zvakaenzana mumvura. Kukurunga hakufanirwe kunge kwakanyanya kukurumidza kudzivirira mabubbles uye agglomeration. Kukurunga kwepakati nepakati kunowanzo kurudzirwa.
Kunyungudika kwakamira: Mushure mekupararira kwakakwana, zvinowanzo dikanwa kumira kwenguva yakati (kazhinji maawa akati wandei kana kupfuura) kuti HEC inyungudike zvachose uye igadzire mhinduro yakafanana. Nguva yekumira inoenderana nehuremu hwemamorekuru eHEC uye huwandu hwemhinduro.
Kugadzirisa viscosity: Kana viscosity ichida kugadziriswa, huwandu hweHEC hunogona kuwedzerwa kana kuderedzwa zvakakodzera. Pamusoro pezvo, hunogonawo kugadziriswa nekuwedzera ma electrolytes, kuchinja pH value, nezvimwewo.
Kungwarira mukuparadzwa
Dzivisa kuungana: Hydroxyethyl cellulose iri nyore kuungana, saka kana uchiwedzera hupfu, nyatsoteerera kuisasa zvakaenzana. Sefa kana chimwe chinhu chekuparadzira chinogona kushandiswa kubatsira kupararira zvakaenzana.
Tembiricha yekudzora: Tembiricha yekunyungudutsa haifanirwe kunge yakanyanya kukwira, zvikasadaro inogona kukonzera kudzikira kweHEC pakupisa uye kukanganisa mashandiro emushonga. Kazhinji zvakakodzera kuidzora iri pakati pe30°C ne50°C.
Dzivisa mhepo kupinda: Dzivisa kukurunga nekukurumidza kudzivirira mhepo kupinda mumushonga kuti igadzire maburi. Maburi anokanganisa kufanana uye kujeka kwemushonga.
Sarudza michina yekukurunga yakakodzera: Sarudza michina yekukurunga yakakodzera zvichienderana nekusimba kwemushonga. Kune mhinduro dzisina kusimba zvakanyanya, zvinokurunga zvakajairika zvinogona kushandiswa; kune mhinduro dzine kusimba kwakanyanya, zvinokurunga zvakasimba zvinogona kudiwa.
Kuchengetedza nekuchengetedza:
Mushonga weHEC wakanyungudutswa unofanira kuchengetwa mumudziyo wakavharwa kudzivirira hunyoro kana kusvibiswa. Kana wakachengetwa kwenguva yakareba, dzivisa chiedza chezuva chakananga uye mamiriro ekunze anodziya zvakanyanya kuti uve nechokwadi chekuti mushonga wacho wakasimba.
Matambudziko nemhinduro dzakajairika
Kuputsika kusina kuenzana:
Kana kunyungudika kusina kuenzana, zvinogona kunge zvichikonzerwa nekuti upfu hwakasaswa nekukurumidza kana kuti hwakasakungwa zvakakwana. Mhinduro ndeyekuvandudza kufanana kwekukurunga, kuwedzera nguva yekukurunga, kana kugadzirisa kumhanya kwekuwedzera upfu panguva yekukurunga.
Kugadzirwa kwemabhurumu:
Kana mabhuru akawanda akaonekwa mumushonga, mabhuru anogona kuderedzwa nekudzora kumhanya kwekukurunga kana kuarega akamira kwenguva yakareba. Kune mabhuru atoumbwa, mushonga wekubvisa gasi unogona kushandiswa kana kurapwa ne ultrasound kunogona kushandiswa kuabvisa.
Viscosity yemushonga yakakwira zvakanyanya kana kuti yakaderera zvakanyanya:
Kana viscosity yemushonga isingasvike zvinodiwa, inogona kudzorwa nekugadzirisa huwandu hweHEC. Pamusoro pezvo, kugadzirisa pH uye simba reionic remushonga zvinogonawo kukanganisa viscosity.
Unogona kunyungudutsa hydroxyethyl cellulose zvinobudirira wowana mhinduro yakafanana uye yakagadzikana. Kuziva matanho akakodzera ekushandisa uye matanho ekudzivirira kunogona kuwedzera simba re hydroxyethyl cellulose mumashandisirwo akasiyana-siyana.
