Zvitatu zvakakosha maindekisi eanionic polyacrylamide ari mamorekuru uremu, degree rehydrolysis, uye yakasimba zvemukati. Iwo makuru maindekisi eecationic polyacrylamide ari ionic degree, yakasimba zvemukati, uye mamorekuru uremu. Iyo molecular uremu hwe anionic polyacrylamide inotangira pamamirioni matanhatu kusvika pamamirioni makumi maviri nemaviri, uye iyo ionic degree yecationic polyacrylamide masosi kubva 20% kusvika 60%. Munguva pfupi yapfuura, vatengi vazhinji vasiri mumunda vanopindura kuti mhedzisiro yekuwedzera polyacrylamide haina kunaka. Oubo Chemical mvura yekurapa PAM fekitori sewage kurapwa maitiro uye michina.
Iyo dhigirii yehydrolysis ye polyacrylamide yakaderera pane iya yezvimwe zvakafanana zvigadzirwa. Kune mamwe akasungunuka flocculants, iyo yakakwira iyo mwero weionization, iyo yakawanda ions inoenderana nemamousu, uye isina kusimba degree rehydrolysis. Semazuva ese, iyo hydrolysis chiyero chePAM ine yakakwira kubhadharisa kukosha inokurumidza kupfuura iyo yePAM ine yakaderera mutengo ukoshi.
Zvino, nei simba rekurapa kwemvura isina tsvina nePAM richisvika pane zvataurwa nemugadziri? Izvi zvinotevera zvikonzero nemaonero aOubo Chemical:
1. Nguva yekunyungudika: polyacrylamide inofanira kuiswa nekukurumidza mushure mekunyungudika kuita mvura. Nekuwedzera kwenguva yekuchengetera, mushonga unodzikira neakareba nguva yekuchengetera. Iyo viscosity yemvura ichave yakaderera, uye mhedzisiro yekurapwa kweseweji ichanyanya kukanganiswa. Semazuva ese, polyacrylamide mvura inogona kuchengetwa kwemazuva 1-2. Nguva yekuchengetedza ye solid polyacrylamide yakareba. Zvinokurudzirwa kuti mutengi ashandise polyacrylamide aqueous solution parizvino.
2. Kupisa: kana iyo polyacrylamide mvura yakaenzana, inotanga kudzikira zvishoma nezvishoma kana tembiricha yasvika 60 ℃. Iyo anionic flocculant ine mamirioni makumi maviri nemasere ehuremu ichadzikira kusvika pamamirioni mashanu kana yasvika kune tembiricha isingadzivisike, inozoparadza mamorekuru emaketani. Iko kushanda kweshanduro yemumvuri chikamu kuchadzora nekukurumidza uye nekukurumidza nekuwedzera kwetembiricha.
3. Kusanganisa: muchina unosanganisa unogona kufambisira mberi mwero wekudzora we polyacrylamide, asi muyero wekusanganisa wakanyanya, uyo unogura mamorekuru cheni marongero e polyacrylamide. Zvinokurudzirwa kuti musanganisi adzore kumhanya kwe150 rpm, uye usashandise yakasimba-kusanganisa zvinhu uye zvekumhanyisa-zvekufambisa zvekushandisa.
4. Hunhu hwemvura: Oubo Kemikari kurapwa kwemvura polyacrylamide inogadzira inoratidza kuti isina kwayakajeka mvura yakachena kana mvura yemupombi inofanira kushandiswa kukurudzira uye kubvisa. Kana mhando yemvura yemurwizi ikaiswa, polyacrylamide ablation inozokanganiswa. Nekuti mvura yemurwizi ine zvisakachena, iyo viscosity ye polyacrylamide uye mhedzisiro yekuraswa kwetsvina kurangwa
