PDADMAC Coagulant: Tšoaro e Sireletsehileng, Tekanyetso, le Tataiso ea Kopo

PolyDADMAC ke polima ea cationic e sebetsang hantle haholo. E sebelisoa haholo ho hloekisa metsi, ho etsa pampiri, masela le masimo a mang ka lebaka la liphello tse tsotehang tsa ho tlosa lintho tse tiileng tse emisitsoeng, ho senya metsi a litšila le ho ntlafatsa ts'ebetso ea ho hloekisa. Joalo ka manyolo a sebetsang hantle haholoCoagulant, ts'ebetso e bolokehileng, litekanyetso le ts'ebeliso ea PDADMAC li hohetse tlhokomelo e ngata. Sengoliloeng sena se tla fana ka litataiso tse qaqileng mabapi le ts'ebetso e bolokehileng, litekanyetso tse khothalelitsoeng le mekhoa e metle ea ts'ebeliso ea lik'hemik'hale tsa PDADMAC ho u thusa ho ntlafatsa ts'ebetso ha u ntse u netefatsa polokeho le ho latela melao.

PDDMAC ke polima e qhibilihang ka metsing, e nang le mela e nang le litefiso tse matla tse ntle. E fumaneha ka mokhoa oa mokelikeli (20% -40%), 'me ka linako tse ling e le phofo bakeng sa lisebelisoa tse khethehileng. E lumellana le mefuta e mengata ea maemo a pH (e sebetsang ho tloha pH 3 ho ea ho 10) 'me e sebetsa hantle metsing a tlaase le a phahameng a metsi.

Lintho tse ka sehloohong tsaPolyDADMAC:

* Ponahalo: Mokelikeli o se nang mebala ho isa ho o mosehla o mosehla oa viscous

* Tefiso ea Ionic: Cationic

* Solubility: E qhibiliha ka ho feletseng metsing

* pH: 4-7 (1% tharollo)

* Boima ba limolek'hule: E ka fapana ho tloha tlase ho ea holimo ho latela ts'ebeliso

Lisebelisoa tsa PDADMAC

PDADAC e sebelisoa hangata libakeng tse latelang:

1. Phekolo ea Metsi le Metsi a Litšila: E le thuso ea mantlha ea coagulant kapa coagulant, PDADMAC e ntlafatsa sedimentation le sludge dewatering ho hloekisa metsi a litšila a masepala le indasteri.

2. Indasteri ea Pulp le Pampiri: E ntlafatsa ho boloka le ho ntša metsi, e ntlafatsa boleng ba pampiri, 'me e sebetsa e le mokhoa oa ho lokisa lithōle tsa anionic.

3. Indasteri ea Masela: E sebetsa e le moemeli oa ho lokisa dae, e ntlafatsa ho potlaka ha mebala.

4. Oilfield le Mining: E ​​sebelisoa bakeng sa ho hlakisa metsi, phekolo ea seretse, le ho senya emulsification.

Tšoaro e Sireletsehileng ea PDADMAC

Le hoja PDADMAC e nkoa e le tlaase ho chefo, mekhoa e nepahetseng ea ho sebetsana le eona e lokela ho lateloa kamehla ho netefatsa polokeho ea basebetsi le ho thibela tšusumetso ea tikoloho.

1. Thepa ea Tšireletso ea Motho (PPE)

* Apara liatlana tse thibelang lik'hemik'hale, liaparo tsa tšireletso le likhalase tsa tšireletso.

* Tabeng ea aerosol kapa mouoane, sebelisa tšireletso e nepahetseng ea phefumoloho.

2. Maemo a polokelo

* Boloka sebakeng se pholileng, se omeletseng, se nang le moea o motle.

* Boloka lijana li tiisitsoe ka thata.

* Qoba ho ba le serame kapa ho pepesehela mocheso nako e telele.

3. Mehato ea Thuso ea Pele

* Ho ama letlalo: Hlatsoa ka metsi a mangata 'me u tlose liaparo tse silafetseng.

* Ho shebana le mahlo: Hlatsoa mahlo ka metsi bonyane metsotso e 15.

* Ho hema: E-ea moeeng o hloekileng 'me u batle thuso ea bongaka haeba matšoao a sa khaotse.

* Ho ja: Se ke oa etsa hore motho a hlatse. Hlatsoa molomo 'me u batle keletso ho ngaka.

Tataiso ea litekanyetso tsa PDDMAC

Tekanyo e nepahetseng ea PDDMAC e ipapisitse le ts'ebeliso e ikhethileng, litšobotsi tsa metsi, le lipheo tsa kalafo. Ka tlase ke likhothaletso tsa litekanyetso tse akaretsang:

Tlhokomeliso: Ho khothaletsoa ho etsa liteko tsa linkho kapa liteko tsa sefofane ho fumana hore na litekanyetso tse sebetsang ka ho fetisisa tlas'a maemo a ikhethileng a sebaka.

Mekhoa ea Kopo

PDADAC e ka eketsoa ka kotloloho metsing a metsi kapa ea tsoakoa le lik'hemik'hale tse ling tsamaisong ea dosing. Litaelo tse ling tsa liphetho tse nepahetseng ke tsena:

1. Dilution: Mokelikeli oa PDADMAC o ka hlapolloa ka metsi ka karolelano ea 1:5 ho isa ho 1:20 pele o noa bakeng sa ho hasana hantle.

2. Ho kopanya: Etsa bonnete ba hore ka ho feletseng esita le ho kopanya tsamaisong ea phekolo ho eketsa sebopeho sa floc.

3. Tatelano: Haeba e sebelisoa le li-flocculants tse ling (mohlala, polyacrylamide), eketsa PDADMAC pele ho lumella nako e lekaneng ea ho itšoara.

4. Tlhokomelo: Kamehla hlokomela turbidity, molumo oa seretse, le matšoao a mang a bohlokoa ho lokisa litekanyetso ka nako ea nnete.

Mehopolo ea Tikoloho

PDADAC ka kakaretso e nkuoa e bolokehile tikolohong ha e sebelisoa ka nepo. Leha ho le joalo, ho tsoa ho feteletseng ho ka ama bophelo ba metsing ka lebaka la tlhaho ea eona e matla ea cationic. Kamehla latela melao ea lehae bakeng sa ho lahla metsi a litšila 'me u qobe ho lokolloa ho sa laoleheng metsing a tlhaho a metsi.

Hore na o laola setsi sa kalafo sa masepala, o sebetsa ntlo ea dae ea masela, kapa o sebetsa indastering ea makhasi le pampiri, PDADMAC e fana ka ts'ebetso e tšepahalang le liphetho tse ts'oanang.

Haeba u batla e ka tšeptjoangMofani oa PDADMACka boleng bo tsitsitseng le likhetho tse feto-fetohang tsa ho paka, ikutloe u lokolohile ho ikopanya le sehlopha sa rona sa tekheniki bakeng sa tharollo ea tloaelo e lumellanang le litlhoko tsa indasteri ea hau.
