Polyacrylamide (PAM) mutsara wepolymer ine flocculation, adhesion, kuderedza kudhonza, uye zvimwe zvivakwa. Sezvo aPolymer Organic Flocculant, inoshandiswa zvakanyanya mumunda wekuchenesa mvura. Paunenge uchishandisa PAM, nzira dzakakodzera dzekushanda dzinofanira kuteverwa kudzivirira kuparara kwemakemikari.
PAM Kuwedzera Maitiro
ForSolid PAM, inoda kuwedzerwa kumvura mushure mokunge yanyungudutswa. Kune hunhu hwakasiyana hwemvura, mhando dzakasiyana dzePAM dzinoda kusarudzwa, uye mhinduro dzakaganhurwa muzvikamu zvakasiyana. Kana uchiwedzera polyacrylamide, kutarisisa kunofanirwa kubhadharwa kune zvinotevera pfungwa:
Jar Miedzo:Sarudza iyo yakanyanya kutaurwa uye dosage kuburikidza nejaja bvunzo. Mune bvunzo dzechirongo, zvishoma nezvishoma wedzera dosi yepolyacrylamide, tarisa iyo flocculation mhedzisiro, uye uone iyo yakakwana dosage.
Kugadzirira PAM Aqueous Solution:Sezvo anionic PAM (APAM) uye nonionic PAM (NPAM) vane huremu hwemamorekuru hwepamusoro uye simba rakasimba, anionic polyacrylamide inowanzogadzirwa kuita mvura ine mvura ine musanganiswa we0.1% (zvichireva kune yakasimba zvinhu) uye isina munyu, yakachena isina kwayakarerekera mvura. Sarudza enameled, galvanized aluminium, kana mabhakiti epurasitiki pachinzvimbo chemidziyo yesimbi sezvo maion esimbi anokonzeresa kuparara kwemakemikari ePAM yese. Panguva yekugadzirira, polyacrylamide inoda kusaswa zvakaenzana mumvura inobvongodza uye kudziyisa zvakakodzera (<60°C) kuti ikurumidze kuparara. Pakunyunguduka, kutarisisa kunofanirwa kubhadharwa kuwedzera chigadzirwa zvakaenzana uye zvishoma nezvishoma mukati mekunyungudika nekukurudzira uye kupisa matanho kudzivirira kusimba. Mushonga wacho unofanirwa kugadzirirwa pane tembiricha yakakodzera, uye kuveura kwenguva refu uye kwakaomarara kunofanirwa kudziviswa. Zvinokurudzirwa kuti musanganisi anotenderera pa60-200 rpm; zvikasadaro, zvinokonzeresa kuparara kwepolymer uye kukanganisa mashandisiro ekushandisa. Ziva kuti iyo PAM aqueous solution inofanira kugadzirirwa nekukurumidza isati yashandiswa. Kuchengetedza kwenguva refu kuchaita kuti zvishoma nezvishoma kuderera kwekuita. Mushure mekuwedzera flocculant aqueous solution kune kumira, kubvongodza kwakasimba kwenguva yakareba kuchaparadza flocs dzakaumbwa.
Dosing Zvinodiwa:Shandisa dosing mudziyo kuwedzera PAM. Muchikamu chekutanga chekuita kwekuwedzera PAM, zvakakosha kuwedzera mikana yekubatana pakati pemakemikari nemvura kuti inorapwa zvakanyanya sezvinobvira, kuwedzera kukurudzira, kana kuwedzera kuyerera kwekuyerera.
Zvinhu zvekucherekedza Paunenge uchiwedzera PAM
Nguva yekupera:Mhando dzakasiyana dzePAM dzine nguva dzakasiyana dzekupera. Cationic PAM ine nguva ipfupi yekunyungudika, nepo anionic uye nonionic PAM ine nguva refu yekuparara. Kusarudza iyo yakakodzera nguva yekumisa kunogona kubatsira kuvandudza iyo flocculation effect.
Dose uye Concentration:Yakakodzera dosage ndiyo kiyi yekuwana yakanakisa flocculation maitiro. Yakawandisa dosage inogona kukonzera yakawandisa coagulation yemacolloid uye yakamiswa zvimedu, ichigadzira madhiri makuru pachinzvimbo che flocs, zvichikanganisa kunaka kwetsvina.
Mixing Conditions:Kuti uve nechokwadi chekusanganiswa kwakakwana kwePAM nemvura yakasvibiswa, zvakakodzera kusanganisa michina uye nzira dzinoda kusarudzwa. Kusaenzana kusanganisa kunogona kukonzera kusakwana kuparara kwePAM, nekudaro ichikanganisa flocculation yayo.
Mamiriro Ezvakatipoteredza Mvura:Zvakatipoteredza zvinhu zvakaita sepH kukosha, tembiricha, kudzvanywa, nezvimwe, zvichakanganisawo flocculation mhedzisiro yePAM. Zvichienderana nemararamiro emhando yemvura yetsvina, aya ma paramita angangoda kugadziriswa kuti awane mhedzisiro yakanaka.
Dosing Sequence:Mune akawanda-agent dosing system, zvakakosha kuti unzwisise kutevedzana kwedosing yeakasiyana vamiririri. Iyo isiriyo dosing inoteedzana inogona kukanganisa kudyidzana pakati pePAM uye colloids uye yakamiswa zvimedu, nekudaro ichikanganisa iyo flocculation effect.
Polyacrylamide(PAM) i polymer inoshanda zvakasiyana-siyana ine akasiyana maapplication, kunyanya mukurapa kwemvura. Kuti iwedzere kushanda kwayo uye kudzivirira kutambisa, zvakakosha kutevedzera nzira dzekushanda dzakafanira. Nekunyatsofunga zvinhu zvakaita senge nguva yekunyungudika, dosi, kusanganisa mamiriro, mamiriro emvura ezvakatipoteredza, uye kutevedzana kwedosing, unogona kunyatsoshandisa PAM kuti uwane inodiwa flocculation mhedzisiro uye kuvandudza mhando yemvura.
