I-PDADMAC Coagulant: Ukuphatha Okuphephile, Umthamo, kanye Nomhlahlandlela Wohlelo

I-PolyDADMAC iyi-polymer ye-cationic esebenza kahle kakhulu. Isetshenziswa kabanzi ekwelashweni kwamanzi, ukwenza amaphepha, izindwangu kanye neminye imikhakha ngenxa yemiphumela yayo emangalisayo ekususeni izinto eziqinile ezimisiwe, ukukhipha umbala wamanzi angcolile kanye nokwenza ngcono ukusebenza kokuhlunga. Njenge-organic esebenza kahle kakhuluI-coagulant, ukuphathwa okuphephile, umthamo kanye nokusetshenziswa kwe-PDADMAC kudonse ukunaka okukhulu. Lesi sihloko sizohlinzeka ngemihlahlandlela enemininingwane yokuphatha okuphephile, umthamo onconyiwe kanye nezinqubo ezingcono kakhulu zokusetshenziswa kwamakhemikhali e-PDADMAC ukukusiza uthuthukise ukusebenza ngenkathi uqinisekisa ukuphepha nokuhambisana.

I-PDADMAC iyi-polymer encibilikayo emanzini, ewumugqa enezindleko eziqondile eziqinile. Ivamise ukutholakala iwuketshezi (20%–40%), futhi ngezinye izikhathi iwumpushana ukuze isetshenziswe ngokukhethekile. Ihambisana nezinhlobonhlobo zezimo ze-pH (isebenza kusukela ku-pH 3 kuya ku-10) futhi isebenza kahle emanzini aphansi naphezulu.

Izici ezibalulekile zeI-PolyDADMAC:

* Ukubukeka: Uketshezi lwe-viscous olungenambala olungenambala oluphuzi

* I-Ionic charge: Cationic

* I-Solubility: Incibilika ngokuphelele emanzini

* pH: 4–7 (1% solution)

* Isisindo samangqamuzana: Singahluka ukusuka kokuphansi kuye phezulu kuye ngohlelo lokusebenza

Izicelo ze-PDADAC

I-PDADAC ivame ukusetshenziswa kulezi zindawo ezilandelayo:

1. Ukuhlanza Amanzi Namanzi Angcolile: Njengosizo oluyisisekelo lwe-coagulant noma i-coagulant, i-PDADMAC ithuthukisa ukuthungwa kwamanzi kanye nokukhipha udaka ekuhlanzeni amanzi angcolile kamasipala nezimboni.

2. Imboni ye-Pulp kanye Nephepha: Ithuthukisa ukugcinwa kanye nokukhipha amanzi, ithuthukisa ikhwalithi yephepha, futhi isebenza njengento yokulungisa udoti we-anionic.

3. Imboni Yezindwangu: Isebenza njenge-ejenti yokulungisa udayi, ithuthukisa ukushesha kombala.

4. I-Oilfield and Mining: Isetshenziselwa ukucaciswa kwamanzi, ukuhlanzwa kwe-sludge, kanye nokuphulwa kwe-emulsification.

Ukuphatha Okuphephile kwe-PDADMAC

Nakuba i-PDADMAC ibhekwa njengobuthi obuphansi, izinqubo ezifanele zokuphatha kufanele zihlale zilandelwa ukuze kuqinisekiswe ukuphepha kwabasebenzi nokuvimbela umthelela wendawo.

1. Izinto Zokuzivikela Zomuntu Siqu (PPE)

* Gqoka amagilavu amelana namakhemikhali, izingubo zokuzivikela, nezibuko zokuphepha.

* Uma kwenzeka kuba ne-aerosol noma umhwamuko, sebenzisa isivikelo sokuphefumula esifanele.

2. Izimo zokugcina

* Gcina endaweni epholile, eyomile futhi enomoya omuhle.

* Gcina iziqukathi zivalwe ngokuqinile.

* Gwema ukubanda noma ukuchayeka isikhathi eside emazingeni okushisa aphezulu.

3. Izinyathelo Zosizo Lokuqala

* Ukuthinta isikhumba: Hlanza ngamanzi amaningi futhi ukhiphe izingubo ezingcolile.

* Ukuthintana kwamehlo: Hlanza amehlo ngamanzi okungenani imizuzu eyi-15.

* Ukuhogela: Hambisa emoyeni omusha futhi ufune usizo lwezokwelapha uma izimpawu ziqhubeka.

*Ukungenisa: Ungabangeli ukuhlanza. Hlanza umlomo futhi ufune iseluleko sezokwelapha.

PDADMAC Dosage Guide

Umthamo ophelele we-PDADMAC uncike ekusetshenzisweni okuqondile, izici zamanzi, nezinjongo zokwelashwa. Ngezansi izincomo zomthamo ojwayelekile:

Qaphela: Kuyanconywa ukwenza izivivinyo zembiza noma ukuhlola kokuhlola ukuze kutholwe umthamo osebenza kahle kakhulu ngaphansi kwezimo eziqondene nesayithi.

Izindlela Zokusebenza

I-PDADMAC ingangezwa ngqo emfudlaneni wamanzi noma ixutshwe namanye amakhemikhali ohlelweni lomthamo. Nayi eminye imihlahlandlela yemiphumela emihle:

1. I-Dilution: Uketshezi lwe-PDADMAC lungahlanjululwa ngamanzi ngesilinganiso sika-1:5 kuya ku-1:20 ngaphambi kokudosa ukuze kuhlakazwe kangcono.

2. Ukuxuba: Qinisekisa ukuthi uxube ngokuphelele futhi uxuba ohlelweni lokwelapha ukuze ukwandise ukwakheka kwe-floc.

3. Ukulandelana: Uma isetshenziswa namanye ama-flocculants (isb, i-polyacrylamide), engeza i-PDADMAC kuqala ukuze uvumele isikhathi esanele sokuphendula.

4. Ukuqapha: Qhubeka uqaphe i-turbidity, umthamo we-sludge, nezinye izinkomba ezibalulekile ukuze ulungise umthamo ngesikhathi sangempela.

Ukucatshangelwa Kwemvelo

I-PDADMAC ijwayele ukuthathwa njengephephile ngokwemvelo uma isetshenziswa ngendlela efanele. Kodwa-ke, ukukhishwa ngokweqile kungase kuthinte impilo yasemanzini ngenxa yemvelo yayo eqinile ye-cationic. Hlala ulandela imithetho yendawo yokulahlwa kwamanzi angcolile futhi ugweme ukukhishwa okungalawuleki emanzini emvelo.

Noma ngabe uphethe isikhungo sokwelapha sikamasipala, usebenzisa indlu yokudaya yezindwangu, noma usebenza embonini ye-pulp nephepha, i-PDADMAC inikeza ukusebenza okuthembekile nemiphumela engaguquki.

Uma ufuna okuthembekilePDADMAC umphakelingekhwalithi ezinzile kanye nezinketho zokupakisha eziguquguqukayo, zizwe ukhululekile ukuxhumana nethimba lethu lezobuchwepheshe ukuze uthole isisombululo esingokwezifiso esifanelana nezidingo zemboni yakho.
