Polyacrylamide Molecular Mvura Kurapa Makemikari
Polyacrylamide (PAM) izwi rinowanzoreva acrylamide homopolymer kana copolymerized nemamwe mamonomers, uye ndeimwe yemhando dzinoshandiswa zvakanyanya dzemapolymer anonyungudika nemvura.Nekuda kwekuti chimiro chepolyacrylamide chine zvikwata zveamide, zviri nyore kuumba hydrogen zvisungo, izvo zvinoita kuti ive yakanaka solubility yemvura uye yakakwirira kemikari kuita, uye zviri nyore kuwana zvigadziriso zvakasiyana-siyana zvebranched cheni kana network chimiro kuburikidza nekubatanidza kana kuchinjika., Inoshandiswa zvakanyanya mukutsvaga petroleum, kurapwa kwemvura, textile, papermaking, mineral processing, mishonga, kurima uye mamwe maindasitiri, uye inozivikanwa se "vabatsiri kune ese maindasitiri".Minda mikuru yekushandisa munyika dzekunze ndeye kurapwa kwemvura, kugadzira mapepa, migodhi, simbi, nezvimwe;muChina, huwandu hukuru huri kushandiswa pari zvino mumunda wekuchera mafuta, uye minda inokurumidza kukura iri muminda yekuchenesa mvura uye kugadzira mapepa.
Nzvimbo yekuchenesa mvura:
Kugadziriswa kwemvura kunosanganisira kurapwa kwemvura yakasvibirira, kuchenesa tsvina uye kugadzirwa kwemvura mumaindasitiri.Inoshandiswa pamwe chete neiyo activated kabhoni mukurapwa kwemvura mbishi, inogona kushandiswa kubatanidza uye kujekeswa kwezvimedu zvakamiswa mumvura yemumba.Kushandiswa kwe organic flocculant acrylamide panzvimbo ye inorganic flocculant kunogona kuwedzera simba rekuchenesa mvura neanopfuura 20% kunyange pasina kugadzirisa kugadzirisa tangi;mukurapwa kwetsvina, kushandiswa kwepolyacrylamide kunogona kuwedzera chiyero chekushandiswa kwemvura zvakare uye inogona kushandiswa seSludge dewatering;inoshandiswa seyakakosha yekugadzira mumiririri muindasitiri yekurapa mvura.Munda mukuru wekushandiswa kwepolyacrylamide kunze kwenyika ndeye kurapwa kwemvura, uye kushandiswa mumunda uyu muChina kuri kusimudzirwa.Basa guru re polyacrylamide mukurapa kwemvura: [2]
(1) Deredza huwandu hwe flocculant.Pasi pemamiriro ekuwana mhando yemvura yakafanana, polyacrylamide inoshandiswa se coagulant rubatsiro pamwe chete nemamwe flocculants, iyo inogona kuderedza zvakanyanya kuwanda kwe flocculant inoshandiswa;(2) Kuvandudza kunaka kwemvura.Mukurapa kwemvura yekunwa uye kurapwa kwemvura yakasviba mumaindasitiri, kushandiswa kwepolyacrylamide mukubatana neinorganic flocculants kunogona kuvandudza zvakanyanya kunaka kwemvura;(3) Wedzera floc simba uye sedimentation velocity.Maflocs akaumbwa ne polyacrylamide ane simba rakakwirira uye yakanaka sedimentation kuita, nokudaro achiwedzera yakasimba-mvura kupatsanurwa kumhanya uye kufambisa sludge kupera mvura mumuviri;(4) Anti-corrosion uye anti-scaling yeinotenderera inotonhorera system.Kushandiswa kwepolyacrylamide kunogona kuderedza zvakanyanya kuwanda kweiyo inorganic flocculants, nekudaro kudzivirira kuiswa kwezvinhu zvisingaite pamusoro pemidziyo uye kuderedza kukora uye kuwedzera kwemidziyo.
Polyacrylamide inoshandiswa zvakanyanya seyamuro yekuchengetedza, sefa yekubatsira, yekuyera mumiriri, nezvimwe mumunda wekugadzira mapepa kuvandudza kunaka kwebepa, slurry dehydration performance, chiyero chekuchengetedza kwemafivha akanaka uye mafirita, kuderedza kushandiswa kwezvinhu zvakasvibiswa uye kusvibiswa kwezvakatipoteredza, Inoshandiswa seanoparadzira kuvandudza kufanana kwepepa.Polyacrylamide inonyanya kushandiswa muzvikamu zviviri muindasitiri yemapepa.Imwe ndeyekuwedzera chiyero chekuchengetedza mafirita uye pigment kuderedza kurasikirwa kwezvinhu zvakasvibiswa uye kusvibiswa kwezvakatipoteredza;imwe yacho ndeyekuwedzera simba repepa.Kuwedzera polyacrylamide kumapepa zvinhu zvinogona kuwedzera mwero wekuchengetwa kwemafibhi akanaka uye zvimedu zvekuzadza pamambure uye nekumhanyisa kupera simba kwepepa.Iyo nzira yekuita yepolyacrylamide ndeyekuti zvimedu zviri muslurry zvinotenderedzwa uye zvinochengetwa pajira resefa nekusagadzikana kana bhiriji.Kuumbwa kwemaflocs kunogonawo kuita kuti mvura iri muslurry ive nyore kusefa kunze, kuderedza kurasikirwa kwefiber mumvura chena, kuderedza kusvibiswa kwezvakatipoteredza, uye kubatsira kuvandudza kushanda kwesefa uye sedimentation michina.
