I-Polyaluminum Chloride (PAC)
I-Polyaluminum Chloride (PAC), ebizwa ngokuthi yi-polyaluminum ye-pulyalum i-tulinum chloride dosing ekwelashweni kwamanzi, inefomula yamakhemikhali i-Al₂cln (oh) ₆-n. I-Polyaluminum Chloride Coagulant iyi-ejenti yokwelashwa yamanzi ye-inormer enamanzi anesisindo esikhulu samangqamuzana kanye necala eliphakeme elikhiqizwa ngumphumela wokubopha ama-hydroxide ion kanye ne-polymerization ye-polyvalent anions. I-Poly Aluminium Chlominum Chlomide PAC ingahlukaniswa ibe yi-adged ne-ketshezi ngefomu. I-Solid Polyaluminum Yellow, Grey-Green-Green, I-Dark Brown Powder. Uketshezi lwe-PAC lithinteka kalula ngumswakama futhi lincibilika kalula emanzini. Inqubo ye-hydrolysis ihambisana nezinqubo zomzimba nezamakhemikhali ezifana ne-electrochechemistry, i-agglutation, i-adsorption, kanye nemvula, futhi inezakhiwo eziqinile zokubopha ama-adsorption.
1. Indlela yokusebenza
Isixazululo samanzi samakhemikhali e-PAC ngumkhiqizo we-hydrolysis phakathi kwe-Fecl₃ ne-al (oh) ₃, nge-colloidal ekhokhiswayo, ngakho-ke inenhloso eqinile yokumisa ama-solids emanzini asusiwe emanzini.
2. Izici zomkhiqizo
● I-Polyaluminum Cloride izinzile ngamakhemikhali emazingeni okushisa asekamelweni, futhi ngeke ziwohloke ngemuva kokugcinwa isikhathi eside. I-polyaluminum eqinile idonsa kalula umswakama, kepha ayiwona amandla, futhi ayinobuthi futhi ayinangozi.
● Inani le-PH yebanga elifanele lamanzi lingu-4-14, kepha inani le-PH le-PH yokwelashwa lingu-6-8.
● I-Poly Aluminium Chloride Powder inezimpawu zemithamo emincane, izindleko eziphansi, umsebenzi ophakeme, ukusebenza okulula, ukusetshenziswa okubanzi kanye nokuhlushwa okuphansi kanye nokuhlushwa okuphansi.
Polycrylamide (pam)
I-Polyacrylamide (Pam) / I-Nonionic Polyacrylamide / I-Poly Polylamide / Anionic PolyAcrylamide, i-Alias Flocculont No. 3, i-polymer enezinkinga zamanzi eyakhiwe nge-polymeride yamahhala ye-acrymide (AM) Monomer. Ukuhlangana kanye nenqubo ye-floccution ekwelashweni kwamanzi, ama-polylacrylamide SDs anokufukula okuhle futhi anganciphisa ukuxabana phakathi kokumelana nama-anionic, i-amphoteric kanye ne-amphotec ngokwezindawo ze-ionic.
I-Polyacrylamide iyinqwaba ye-White Pop Parkle, engachithwa emanzini kunoma yisiphi ingxenye, ikhambi elinamanzi alifani futhi lisobala, futhi ukubonwa kwesisombululo esinamanzi kwandisa kakhulu isisindo se-polymer. UPam uyangena ngaphakathi ezinhlakeni eziningi ze-organic, ezinjenge-formaldehyde, ethanol, acetone, ether, njll.
1. Indlela yokusebenza
I-Polyacrylamide iyi-polymer esolulekile yamanzi noma i-polyelectlyte yamanzi. Kunenombolo ethile yamaqembu ama-polar ku-pam molecular chain, engafakwa ama-addebb izinhlayiya eziqinile ezimiswe indle, zenze amabhuloho phakathi kwezinhlayiya noma ngokushayisana, ukuze izinhlayiya zikwazi ukwakha ama-flocs amakhulu. Ngakho-ke, i-polylacrylamide ingasheshisa ama-solids amiswe. Ukudonswa kwezinhlayiya eziphakathi kunomphumela osobala wokusheshisa ukucaciswa kwesixazululo nokukhuthaza ukugcwala.
2. Amanothi
I-PolyAcrylamise iqukethe i-acrymide monomer enobuthi obunobuthi. Ekwelashweni kwamanzi okuphuza ezweni lami, inani elivumelekile lingu-0.01mg / l. Ukuze uvikele ukonakala kwe-polylacrylamide, izinga lokushisa lesitoreji lesisombululo salo esinamanzi kufanele lilawulwe ukuthi lingabi ngaphezu kuka-40 ° C. Ukuze uvikele ukuvezwa elangeni, inani elincane le-stabilizer, njenge-sodium thiocyanate, i-sodium nitrite, njll., Lingangezwa kwikhambi. I-Polyacryrylamide Powder eqinile idinga ukupakishwa kwizigubhu zensimbi ezimbozwe izikhwama ze-polyethylene-proof noma zifakwe ezingqimba ze-polyethylene, futhi zivalwe ukuvimba ukuvezwa komswakama ophezulu.
I-polylicrylamide idinga ukuhlanganiswa bese ibekwa imigqomo ngokhuni noma imiphongolo yensimbi. Isikhathi sokulondolozwa siyizinyanga ezi-3 kuye kwezingu-6. Kudinga ukushukunyiswa ngaphambi kokusebenzisa. Izinga lokushisa lesitoreji akufanele libe ngaphezulu kuka-32 ° C futhi liphansi kune-0 ° C.
