一. Isingeniso sesimiso sokusebenza

Ngesikhathi senqubo yokupenda, izinga lokumboza upende lingama-40 kuya ku-60% kuphela, futhi ngaphezu kwengxenye yopende ingena emoyeni ukuze yakhe inkungu yokufutha, ingcolise kakhulu umoya nendawo ezungezile. Ukuze kuvikelwe imvelo ngempumelelo futhi kuhlanzwe indawo yokwakha, uhlelo lwamanzi olujikelezayo lwebhokisi lokufutha elimanzi luvame ukusetshenziswa embonini yokupenda ukuze kubanjwe inkungu yopende efuthwe ngokweqile. Ukuze kugcinwe ukusebenza kwebhokisi lokufutha, kuthuthukiswe indawo yokusebenza yokupenda, futhi kwenziwe uhlelo lokuhlanza lusebenze ngendlela evamile, inani elincane lamakhemikhali kumele lifakwe futhi ligcinwe emanzini ajikelezayo, aziwa kakhulu ngokuthi ama-coagulants e-paint mist. Ingathintana nezinhlayiya zopende ezibanjwe ngamanzi, bese isabela nayo futhi yenze ingazinzi futhi inamathele, ihlangane ibe yi-flocculant enosayizi othile wezinhlayiya, obizwa ngokuthi i-paint slag, futhi ihlukaniswe namanzi, ukuze umjikelezo wamanzi usetshenziswe isikhathi eside. Ama-coagulant enkuni yopende ahlanganisa kakhulu uhlobo oluqinile lokuhlakazeka kwe-alkali, uhlobo lokumunca komoya, uhlobo lokumunca komoya olusekelwe emanzini, njll. Izinhlobo ezingenhla zemikhiqizo zingenza upende ukhiphe futhi uhlanganise i-flocculate ngezindlela ezilandelayo: ukwenza i-saponification yenkuni yopende, kuqede ukuthamba kwayo, kukhiqize insipho ye-alkali engancibiliki emanzini, ehlakazekile emanzini; Ngesikhathi esifanayo, inkungu yopende ihlanganiswa ngokunciphisa ukushaja kwengqimba yangaphandle yenkuni yopende. Izinhlayiya ezihlanganisiwe zihlanganiswa zibe yi-flocculant ngokushayisana, bese i-polymer flocculant ifakwa emanzini futhi ihlanganiswe ukuze yakhe i-flocculant enkulu.

二. Indlela yokwahlulela kahle umphumela we-paint mist flocculant

Umphumela we-paint mist coagulant ngokuvamile wahlulelwa kusukela ku-slag, amanzi, igwebu, iphunga nokunye.
(1) I-slag yopende: I-viscosity kufanele ibe ncane ngangokunokwenzeka, futhi isilinganiso sokubonakala okuphelele kufanele okungenani sibe ngu-3 kuya ku-4 (i-slag yopende iyi-granular noma isihlabathi esicolekile).
(2) Amanzi: kudivayisi ye-Eisenmann flow slagging, ngaphambi kokufaka i-slagging nangaphambi kokufaka i-ejenti B, upende kufanele ube namanzi ahlakazekile kakhulu, futhi amanzi ngemva kokufaka i-ejenti B kufanele acwebe ngangokunokwenzeka, futhi isilinganiso sekhwalithi yamanzi kufanele okungenani sibe yibanga lesi-3 (singcolile kancane).
(3) Igwebu: ukuphakama kwegwebu echibini kufanele kufaneleke, futhi akufanele kube phezulu kakhulu kunokuphakama kwegwebu elikhiqizwa ngamanzi aqukethe imithi kuphela ngaphansi kwezimo ezifanayo. Igwebu liphakeme kakhulu, okubonisa ukuthi umphumela wokuhlukaniswa kopende namanzi awumuhle.
(4) Iphunga: Ngesikhathi sokusebenza esibekiwe, akufanele kukhiqizwe iphunga elibi elisobala, okubonisa ukuthi uhlelo lwamanzi lunezingozi zamagciwane njengesikhunta namabhaktheriya, futhi kungabangelwa ukuhlukaniswa kabi kopende namanzi, kodwa ukusetshenziswa kwama-coagulants e-paint mist ngeke kukhiqize iphunga elicasulayo, futhi ama-coagulants amaningi e-paint mist anezelwa kuma-antibacterial agents.

Izinto ezithonya umphumela we-paint mist flocculant

(1) Izinhlobo zopende. Nakuba kungekho ukuhlobana okutholiwe phakathi kohlobo lwe-resin nomphumela wokusetshenziswa, kwaziwa ukuthi ama-coagulant e-paint mist azwela i-polarity ye-resin. Ama-coagulant e-paint mist ane-polarity ehlukene kanye ne-hydrophilicity kufanele asetshenziswe ngokulandelana kumapende ane-polarity ehlukene.

(2) Inani le-PH noma i-alkalinity. Kuyaziwa ukuthi i-alkalinity efanele noma i-pH inegalelo ekuqhekekeni kopende. Inani le-pH liphezulu kakhulu, upende uyabhujiswa ukuze izinhlayiya ezizinzile zihlakazeke emanzini okunzima ukuwagoqa, uphansi kakhulu awukwazi ukubhujiswa ngokuphelele. Ukulawula okuvamile kungu-9.0, futhi ukulawula kubaluleke kakhulu ekusebenzeni kwamanzi ajikelezayo.

(3) inqubo yedokodo lokupenda kanye nenqubo yokupenda ngemuva kokwelashwa kwe-slag. Inqubo yegumbi lokupenda elifuthwayo elisetshenziswa kakhulu ifaka phakathi uhlobo lokuwasha, uhlobo lwekhethini lamanzi, uhlobo lokuwasha lwekhethini lamanzi, uhlobo lokujika kwamanzi, uhlobo lwe-Venturi nezinye izinhlobo, kanti izindlela zokususa i-slag ezisetshenziswa kakhulu zifaka phakathi ipuleti lokuklwebha, uhlobo lwe-centrifugal, njll. Inqubo yegumbi lokupenda elifuthwayo, izinga lokugeleza kwamanzi elijikelezayo, ijubane, kanye nendlela yokususa i-slag kuzothinta umphumela wokusetshenziswa.

(4) izici zamakhemikhali. Ukungcola emanzini, njengokuqina, kuzothinta usayizi wezinhlayiya zokusabalala kopende, ngaleyo ndlela kuthinte ukulahleka kwe-viscosity, ngakho-ke ubunzima kufanele bube buncane ngangokunokwenzeka. Ukungcola okufakwe enkambisweni yokupenda ngokufafaza, njengezixazululo, ikakhulukazi izixazululo ezingezona eze-polar, kunganciphisa kakhulu amandla okumunca amanzi ukuze kupendwe inkungu.

(5) Indlela yokulinganisa kanye nokulinganisa i-coagulant ye-paint mist coagulant. Uma umthamo uncane kakhulu, umphumela wokuminyana awulungile, futhi uma umkhulu kakhulu, unomphumela wokusabalala futhi awukhiqizi ukuminyana. Izinqubo ezahlukene zokumunca upende we-spray booth zidinga izindlela ezahlukene zokulinganisa ezifanele, okudingeka zihlolwe futhi zinqunywe ekusetshenzisweni kwangempela.

(6) Izinto ezibangela amagciwane. Ukuhlushwa kwezinto eziphilayo emanzini ajikelezayo kuphezulu kakhulu, futhi izimo zokusebenza zamanzi ajikelezayo zifanelekile ekuzaleni nasekukhuleni kwamagciwane. Uma kungalawulwa ngokucophelela, ukuzala kwamagciwane kuzoba nomthelela omubi ekusetshenzisweni kwama-coagulant e-paint mist. Ama-bacteriostatic agents kufanele engezwe njalo lapho izinga lokushisa liphezulu.
