Polydiallyldimethylammonium chloride(PolyDADMAC) inoshandiswa zvakanyanya cationic polymer flocculant uye inoita basa rakakosha mumunda wekuchenesa mvura. PDADAC inowanzo shandiswa se flocculant uye dzimwe nguva inosanganiswa nealgaecides. Ichi chinyorwa chichatsanangura pamusoro pezvakanakira uye inoshanda kukosha kwekushandiswa kwePolyDADMAC kubva kune zvikamu zvemaitiro ayo ekuita, mamiriro ekushandiswa uye nzira dzakananga dzekuvandudza kugadzirisa kwemvura.
Basic maitiro ePolyDADMAC
PolyDADMAC yakakwira molecular polymer ine nhamba huru yemapoka e cationic muchimiro chayo chemamorekuru, anogona kunyatso adsorb yakamiswa zvimedu uye colloids mumvura. Hunhu hwayo hukuru hunosanganisira:
1. Strong cationicity: Inogona kukurumidza kudzikamisa zvisina kunaka zvakamiswa zvimedu mumvura.
2. Kunyungudika kwemvura kwakanaka: Zviri nyore kunyungudika mumvura uye yakanakira pa-saiti application.
3. Kugadzikana kwemakemikari: Inogona kuchengetedza yakakwira-inoshanda flocculation kuita mune akasiyana pH mazinga, oxidizing nharaunda uye yakakwira mechanic shear nharaunda. PDADAC ine yakasimba chlorine kuramba.
4. Low toxicity: Inosangana nekuchengetedzwa kwezvakatipoteredza uye inokodzera kurapwa kwemvura yekunwa.
Mechanism yekuita yePolyDADMAC mukurapwa kwemvura
Inokanganisa zvidimbu zvakaturikwa uye inochajiswa zvisina kunaka aqueous mhinduro zvinhu mumvura uye inoatenderedza kuburikidza nemagetsi neutralization uye adsorption bridging. Iyo ine zvakakosha mhedzisiro mukubvisa colorization, uye kubviswa kweiyo organic matter.
PolyDADMACinovandudza kugadzirisa kwemvura kuburikidza nenzira dzinotevera:
1. Charge neutralization
Yakaturikwa zvimedu uye colloids mumvura kazhinji inotakura mhosva dzisina kunaka, izvo zvinokonzeresa kurambana pakati pezvimedu uye zvinoita kuti zviome kugadzirisa. Iwo cationic mapoka ePolyDADMAC anogona kukurumidza kudzikamisa mhosva dzisina kunaka, kuderedza kudzongonyedzwa kwemagetsi pakati pezvimedu, uye kukurudzira particle coagulation.
2. Bridging effect
Iyo yakareba-chain chain molecular structure ye-high-viscosity PolyDADMAC inoita kuti iite "bhiriji" pakati pezvikamu zvakawanda, kuunganidza zviduku zviduku muzvikamu zvakakura, nokudaro zvichivandudza sedimentation kushanda.
3. Kusimbisa mambure ekubata maitiro
PolyDADMAC inogona kusimbisa "mambure maitiro" akaumbwa neinorganic coagulant mukurapwa kwemvura kuti inyatsobata yakanaka yakamiswa nyaya, kunyanya muhuturu hwakanyanya kana mvura yakasvibiswa zvakanyanya.
Mamiriro ekushandisa ePolyDADMAC
1. Kunwa mushonga wemvura
PolyDADMAC inoshandiswa se flocculant kubvisa turbidity, yakamiswa zvidimbu uye organic zvinhu kubva mumvura yekunwa. Panguva imwecheteyo, nekuda kwekuderera kwayo muchetura uye hunhu hwekuchengetedza kwezvakatipoteredza, inogona kusangana nemvura yekunwa kuchengetedza zviyero.
2. Kugadziriswa kwemvura yakasviba
Mumanisiparati uye mumaindasitiri ekuchenesa mvura yetsvina, PolyDADMAC inowanzoshandiswa kuvandudza sludge dewatering performance, kuderedza hunyoro hwedhaka keke, uye kuderedza zvakanyanya mari yekushandisa.
3. Kucheneswa kwemvura yeindasitiri
Musimba, petrochemical nemamwe maindasitiri, PolyDADMAC inoshandiswa kuchenesa mvura yemumaindasitiri senge inotonhorera mvura uye boiler mvura kudzikisa scaling uye corrosion njodzi.
4. Papermaking uye textile industry
PolyDADMAC inoshandiswa sekuchengetedza uye kusefa yekubatsira kuvandudza mwero wekuchengetedza mafiber uye mafirita mukugadzira mapepa, uku ichideredza zvirimo zveyakamiswa nyaya mumvura yetsvina.
Matanho ekuvandudza kugadzirisa kwemvura nePolyDADMAC
1. Kugadzirisa dosage control
Iyo dosage yePolyDADMAC yakanyatsoenderana nekusungwa, kugovera saizi yechikamu uye hunhu hunosvibisa hwezvimedu zvakamiswa mumvura. Kukwirisa dosi kuburikidza nekuyedzwa kwejagi kunogona kukwidziridza kuyerera kwayo uku uchidzivirira yakawandisa dosi inotungamira mukuwedzera mutengo kana kusvibiswa kwechipiri kwemvura.
2. Synergistic effect ine inorganic flocculants
Kushandiswa kwePolyDADMAC pamwe chete neinorganic flocculants (senge polyaluminium chloride uye aluminium sulfate) inogona kuwedzera zvakanyanya flocculation effect. Mushure mePolyDADMAC yakamisa kubhadharisa kwepasi kwezvimedu, iwo inorganic flocculants anoenderera mberi kuumba hombe flocs kuburikidza neadsorption uye sedimentation.
3. Kuvandudza otomatiki mwero wemvura yekurapa maitiro
Nerubatsiro rweautomated control system, chaiyo-nguva yekutarisa uye kugadzirisa kwePolyDADMAC dosage inogona kuwanikwa kutarisana nekuchinja kwehutano hwekurapa hunokonzerwa nekushanduka kwemhando yemvura.
4. Natsiridza zvinokurudzira mamiriro
Mushure mekuwedzera PolyDADMAC, yakakodzera inosimudzira kusimba uye nguva inogona kuwedzera dispersibility uye flocculation kushanda kwayo. Kunyanya kubvongodza kunogona kukonzera flocs kutyoka, nepo kusakwana kubvongodza kunoderedza kusanganisa.
5. Gadzirisa pH kukosha
PolyDADMAC inoita zvakanyanya pasi pekusarerekera kune isina simba alkaline mamiriro. Kana uchirapa yakanyanya acidic kana yakanyanya alkaline mvura, kugadzirisa iyo pH kukosha kwemuviri wemvura kunogona kuvandudza zvakanyanya flocculation yayo.
Zvakanakira zvePolyDADMAC
1. Kubudirira kwepamusoro: Kukurumidza kuumbwa kwemaflocs kuvandudza yakasimba-mvura yekuparadzanisa kushanda zvakanaka.
2. Wide range of applications: Inoshanda kune akasiyana emvura hunhu, kunyanya mvura ine yakakwira turbidity uye yakakwira organic yemukati.
3. Kuchengetedza kwezvakatipoteredza: Yakaderera chepfu uye biodegradability, zvinoenderana nekuchengetedzwa kwezvakatipoteredza zvinodiwa.
Semunhu anoshanda zvakanyanyaflocculant, PolyDADMAC ine zvakakosha zvekushandisa zvakanakira mumunda wekurapa kwemvura nekuda kweiyo yakasimba cationicity, yakanaka solubility yemvura uye yakakura kushandiswa. Kuburikidza nekugadzirisa maitiro ekugadzirisa uye maitiro ekushanda, kushanda kwayo kwekurapa mukucheneswa kwemvura yekunwa, suweji uye mvura yemumaindasitiri inogona kuvandudzwa.
