I-PDADMAC Coagulant: Umhlahlandlela Wokuphatha Ngokuphephile, Umthamo, kanye Nokusetshenziswa

I-PolyDADMAC iyi-polymer ye-cationic esebenza kahle kakhulu. Isetshenziswa kabanzi ekuphatheni amanzi, ekwenzeni amaphepha, ezindwangu nakwezinye izinkambu ngenxa yemiphumela yayo emangalisayo ekususeni izinto eziqinile ezilengayo, ekususeni umbala emanzini amdaka nasekuthuthukiseni ukusebenza kokuhlunga. Njenge-organic esebenza kahle kakhuluI-Coagulant, ukuphathwa okuphephile, umthamo kanye nokusetshenziswa kwe-PDADMAC kudonsele ukunaka okukhulu. Lesi sihloko sizohlinzeka ngeziqondiso ezinemininingwane mayelana nokuphathwa okuphephile, umthamo onconywayo kanye nemikhuba emihle yokusebenzisa amakhemikhali e-PDADMAC ukukusiza ukuthi uthuthukise ukusebenza ngenkathi uqinisekisa ukuphepha kanye nokuthobela imithetho.

I-PDADMAC iyi-polymer encibilikayo emanzini, eqondile enamacala aqinile amahle. Ivame ukutholakala ngesimo soketshezi (ukuhlushwa okungu-20%–40%), futhi ngezinye izikhathi ngesimo sempuphu yezinhlelo ezikhethekile. Ihambisana nezimo ezahlukahlukene ze-pH (isebenza kusukela ku-pH 3 kuya ku-10) futhi isebenza kahle kokubili emanzini anomswakama ophansi naphezulu.

Izakhiwo ezibalulekile zeI-PolyDADMAC:

* Ukubukeka: Uketshezi oluqinile olungenambala kuya koluphuzi olukhanyayo

* Ishaja ye-Ionic: I-Cationic

* Ukuncibilika: Kuncibilika emanzini ngokuphelele

* pH: 4–7 (isixazululo esingu-1%)

* Isisindo sama-molecule: Singahluka kusukela phansi kuya phezulu kuye ngokuthi sisetshenziswa kanjani

Izicelo ze-PDADMAC

I-PDADMAC ivame ukusetshenziswa ezindaweni ezilandelayo:

1. Ukwelashwa Kwamanzi Nokungcola: Njenge-coagulant eyinhloko noma i-coagulant, i-PDADMAC ithuthukisa ukuthuthwa kwendle kanye nokususwa kwamanzi odakeni ekuphathweni kwamanzi amdaka kamasipala nawezimboni.

2. Imboni Yama-Pulp kanye Nephepha: Ithuthukisa ukugcinwa kanye nokuphuma kwamanzi, ithuthukisa ikhwalithi yephepha, futhi isebenza njengesithako sokulungisa udoti we-anionic.

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

4. Indawo kawoyela kanye nokumbiwa: Isetshenziselwa ukuhlanzwa kwamanzi, ukwelashwa kodaka, kanye nokuqhekeka kwe-emulsification.

Ukuphathwa Ngokuphephile kwe-PDADMAC

Nakuba i-PDADMAC ibhekwa njengenobuthi obuphansi, izinqubo zokuphatha ezifanele kufanele zilandelwe njalo ukuqinisekisa ukuphepha kwabasebenzi nokuvimbela umthelela emvelweni.

1. Imishini Yokuzivikela Yomuntu Siqu (i-PPE)

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

* Uma usebenzisa i-aerosol noma umusi, sebenzisa isivikelo esifanele sokuphefumula.

2. Izimo Zokugcina

* Gcina endaweni epholile, eyomile, futhi enomoya omuhle.

* Gcina izitsha zivaliwe kahle.

* Gwema ukubanda noma ukuchayeka isikhathi eside emazingeni okushisa aphezulu.

3. Izindlela Zosizo Lokuqala

* Ukuthintana nesikhumba: Hlanza ngamanzi amaningi bese ususa izingubo ezingcolile.

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

* Ukuphefumula: Yiya emoyeni omusha bese ucela usizo lwezokwelapha uma izimpawu ziqhubeka.

* Ukungena: Ungabangeli ukuhlanza. Hlanza umlomo bese ucela iseluleko sikadokotela.

Umhlahlandlela Wokulinganisa we-PDADMAC

Umthamo ofanele we-PDADMAC uncike ekusetshenzisweni okuthile, izici zamanzi, kanye nemigomo yokwelashwa. Nazi izincomo zomthamo ojwayelekile:

Qaphela: Kunconywa ukwenza izivivinyo zamabhodlela noma izivivinyo zokuhlola ukuze kutholakale umthamo osebenza kahle kakhulu ngaphansi kwezimo ezithile zendawo.

Izindlela Zokusebenzisa

I-PDADMAC ingafakwa ngqo emseleni wamanzi noma ixutshwe namanye amakhemikhali ohlelweni lokulinganisa. Nazi ezinye iziqondiso zemiphumela emihle:

1. Ukuxutshwa: Uketshezi lwe-PDADMAC lungaxutshwa ngamanzi ngesilinganiso esingu-1:5 kuya ku-1:20 ngaphambi kokufakwa umthamo ukuze kusakazwe kangcono.

2. Ukuxuba: Qinisekisa ukuthi kuhlanganiswa kahle futhi ngokulinganayo ohlelweni lokwelapha ukuze kwandiswe ukwakheka kwe-floc.

3. Ukulandelana: Uma kusetshenziswa nezinye izinto ezibangela ukushaqeka (isb. i-polyacrylamide), engeza i-PDADMAC kuqala ukuze uvumele isikhathi esanele sokuphendula.

4. Ukuqapha: Qapha njalo ukungcoliswa kwamanzi, ivolumu yodaka, kanye nezinye izinkomba ezibalulekile ukuze ulungise umthamo ngesikhathi sangempela.

Izinto Ezicatshangelwayo Ngezemvelo

I-PDADMAC ngokuvamile ibhekwa njengephephile emvelweni uma isetshenziswa ngendlela efanele. Kodwa-ke, ukukhishwa ngokweqile kungathinta impilo yasemanzini ngenxa yemvelo yayo enamandla ye-cationic. Landela njalo imithetho yendawo yokulahla amanzi amdaka futhi ugweme ukukhishwa okungalawulwa emanzini emvelo.

Kungakhathaliseki ukuthi uphatha isitshalo sokwelapha sikamasipala, usebenza endlini yodayi wezindwangu, noma usebenza embonini ye-pulp nephepha, i-PDADMAC inikeza ukusebenza okuthembekile nemiphumela eqhubekayo.

Uma ufuna umuntu othembekileUmhlinzeki we-PDADMACNgekhwalithi ezinzile kanye nezinketho zokupakisha eziguquguqukayo, zizwe ukhululekile ukuxhumana nethimba lethu lobuchwepheshe ukuthola ikhambi elenziwe ngokwezifiso elifanela izidingo zakho zomkhakha.
