Kodi cationic flocculants wamba ndi chiyani?

Kusamalira madzi ndi gawo lofunika kwambiri pa kayendetsedwe ka chilengedwe, kuonetsetsa kuti madzi ndi otetezeka kuti agwiritsidwe ntchito komanso kugwiritsidwa ntchito m'mafakitale. Chimodzi mwa zinthu zofunika kwambiri m’kachitidwe kameneka ndicho kugwiritsira ntchito timizere ta flocculant—mankhwala amene amalimbikitsa kusonkhanitsa tinthu tolenjekeka kukhala timagulumagulu tambirimbiri, tomwe timatha kuchotsedwa mosavuta m’madzi. Pakati pa mitundu yosiyanasiyana ya flocculants, cationic flocculants ndi othandiza makamaka chifukwa cha malipiro awo abwino, omwe amalumikizana kwambiri ndi tinthu tating'onoting'ono tomwe timapezeka m'madzi onyansa. Nkhaniyi ikufotokoza za cationic flocculants zomwe zimagwiritsidwa ntchito pochiza madzi ndi ntchito zawo.

cationic Polyacrylamides(CPAM)

Cationic Polyacrylamides, ndi ena mwa omwe amagwiritsidwa ntchito kwambiri pamakampani opanga madzi. Kwa ogwiritsa ntchito ambiri, CPAM ndiye chisankho chawo chabwino. Ma polima awa amakhala ndi ma acrylamide subunits, omwe amatha kupangidwa kuti aphatikizepo magulu ogwirira ntchito. Kusinthasintha kwa ma Cationic polyacrylamides kwagona pakulemera kwa mamolekyu osinthika ndi kachulukidwe kake, kuwalola kuti azisinthidwa kuti azigwiritsidwa ntchito mwapadera. Ma C-PAM ndiwothandiza kwambiri pochiza madzi otayira m'mafakitale ndi kuchotsera matope chifukwa chakuyenda bwino kwawo komanso kuchuluka kwa mlingo wocheperako.

Poly (diallyldimethylammonium chloride) (Zithunzi za PolyDADMAC)

PolyDADMAC ndiyomwe imagwiritsidwa ntchito kwambiri ndi cationic flocculant yomwe imadziwika chifukwa cha kachulukidwe kake komanso magwiridwe antchito amadzi. Polima iyi imakhala yothandiza kwambiri pakumangirira ndi kusefukira, zomwe zimapangitsa kukhala chisankho chodziwika bwino pakutsuka madzi akumwa, madzi oyipa, ndi zotayira m'mafakitale. PolyDADMAC imagwira ntchito bwino limodzi ndi ma flocculants ena ndi ma coagulants, kupititsa patsogolo chithandizo chonse popereka njira yolimba yolumikizira tinthu ndi kuchotsa.

Polyamines(PA)

Polyamines ndi gulu lina la cationic flocculants omwe amagwiritsidwa ntchito pochiza madzi. Mankhwalawa, omwe akuphatikizapo poly(dimethylamine-co-epichlorohydrin) ndi mapangidwe ofanana, amawonetsa kachulukidwe amphamvu a cationic, kuwapangitsa kukhala othandiza kwambiri pakuchepetsa tinthu tating'onoting'ono toyipa. Ma polyamines ndiwothandiza kwambiri pakuwunikira madzi osaphika, kuchotsa zinthu zakuthupi, komanso kukonza zinthu zosiyanasiyana zamafuta m'mafakitale. Kukhoza kwawo kupanga magulu owundana kumabweretsa nthawi yokhazikika komanso kumveka bwino kwamadzi oyeretsedwa.

Mapulogalamu ndi Ubwino

Ma cationic flocculants amatenga gawo lofunikira pakugwiritsa ntchito njira zosiyanasiyana zoyeretsera madzi, kuyambira pakuyeretsa madzi otayidwa ndi madzi akumwa komanso kuyeretsa madzi am'mafakitale. Ubwino wawo waukulu ndi kuthekera kwawo kuti azitha kusokoneza tinthu tating'onoting'ono, zomwe zimatsogolera ku mapangidwe a floc mwachangu komanso moyenera. Izi zimabweretsa kumveka bwino, kuchepetsedwa kwa chipwirikiti, komanso kukhathamiritsa kwamadzi onse. Kuphatikiza apo, ma cationic flocculants nthawi zambiri amagwiritsidwa ntchito limodzi ndi mankhwala ena ochizira, monga ma coagulants, kukhathamiritsa njira yochizira ndikukwaniritsa miyezo yoyenera yamadzi.

Kugwiritsiridwa ntchito kwa cationic flocculants n'kofunikira kwambiri pa njira zamakono zochizira madzi, zomwe zimapereka njira zodalirika komanso zodalirika zothetsera tinthu tating'onoting'ono ndikuchotsa. Polyacrylamides, polyamines, PolyDADMAC imayimira ena mwazinthu zodziwika bwino komanso zogwira mtima za cationic flocculants zomwe zilipo masiku ano. Kusinthasintha kwawo, kuchita bwino, ndi kusinthasintha kwawo kumawapangitsa kukhala zida zofunika kwambiri powonetsetsa kupezeka kwa madzi aukhondo ndi otetezeka ogwiritsidwa ntchito mosiyanasiyana.

Zachidziwikire, kusankha kwa flocculant kumadaliranso zomwe wogwiritsa ntchito amagwiritsa ntchito, kapangidwe kazinthu, chilengedwe, ndi zina zambiri.
