一. Intshayelelo yomgaqo wokusetyenziswa

Ngexesha lenkqubo yokupeyinta, izinga lokugquma lepeyinti liyi-40 ukuya kwi-60% kuphela, kwaye ngaphezulu kwesiqingatha sepeyinti itshiza emoyeni ukuze yenze inkungu yokutshiza, ingcolise kakhulu umoya ojikelezileyo kunye nokusingqongileyo. Ukuze kukhuselwe ngokufanelekileyo okusingqongileyo kwaye kucocwe indawo yokwakha, inkqubo yamanzi ajikelezayo yebhokisi yokutshiza emanzi idla ngokusetyenziswa kwishishini lokupeyinta ukuze kubanjwe inkungu yokutshiza egqithisileyo. Ukuze kugcinwe ukusebenza kwebhokisi yokutshiza, kuphuculwe indawo yokusebenza yokupeyinta, kwaye kwenziwe inkqubo yokucoca isebenze ngokuqhelekileyo, kufuneka kongezwe izinto ezincinci zeekhemikhali kwaye zigcinwe emanzini ajikelezayo, aziwa ngokuba zii-coagulants zemiphunga yokupenda. Ingadibana namasuntswana epeyinti abanjwe ngamanzi, ize emva koko iphendule nayo kwaye yenze ukuba ingazinzi kwaye ikhuphe, iqokelele kwi-flocculant enobukhulu obuthile besuntswana, ebizwa ngokuba yi-paint slag, kwaye yahlulwe emanzini, ukuze umjikelo wamanzi usetyenziswe ixesha elide. Ii-coagulants ze-paint mist ziquka ikakhulu uhlobo oluqinileyo lwe-alkali dispersing, uhlobo lwe-condensation adsorption, uhlobo lwe-water-based peint mist condensation, njl. Ezi ntlobo zemveliso zingasentla zingenza ipeyinti ikhuphe kwaye i-flocculate ngezi ndlela zilandelayo: ukwenza i-paint mist saponification, ukususa i-viscosity yayo, ukuvelisa into ye-alkali enganyibiliki emanzini, esasazeke emanzini; Kwangaxeshanye, i-paint mist ifunxwa ngokunciphisa umbane womaleko wangaphandle we-paint mist. Amasuntswana afunxwayo adityaniswa kwi-flocculant ngokungqubana, kwaye emva koko i-polymer flocculant ifunxwa kwaye ivalwe ukuze yenze i-flocculant enkulu.

二. Indlela yokugweba ngokuchanekileyo isiphumo se-paint mist flocculant

Isiphumo se-paint mist coagulant sidla ngokugwetywa ngokusuka kwi-slag, amanzi, i-foam, ivumba njalo njalo.
(1) I-slag yepeyinti: I-viscosity mayibe ncinci kangangoko, kwaye umlinganiselo opheleleyo wokubonakala kufuneka ubuncinci ube yi-3 ukuya kwi-4 (i-slag yepeyinti yi-granular okanye isanti encinci).
(2) Amanzi: kwisixhobo se-Eisenmann flow slagging, ngaphambi kokufaka i-slagging nangaphambi kokufaka i-arhente B, ipeyinti kufuneka ibe namanzi asasazeke kakhulu, kwaye amanzi emva kokufaka i-arhente B kufuneka acace kangangoko, kwaye umgangatho wamanzi kufuneka ube kwinqanaba lesi-3 ubuncinane (ube mdaka kancinci).
(3) Igwebu: ukuphakama kwegwebu echibini kufanele kube kufanelekile, kwaye akufuneki kube phezulu kakhulu kunokuphakama kwegwebu eliveliswa ngamanzi aqulethe amayeza kuphela phantsi kweemeko ezifanayo. Igwebu liphezulu kakhulu, nto leyo ebonisa ukuba isiphumo sokwahlukana kwepeyinti namanzi asilunganga.
(4) Ivumba: Ngexesha lokusebenza elichaziweyo, akufuneki kuveliswe ivumba elibi elibonakalayo, nto leyo ebonisa ukuba inkqubo yamanzi ineengozi zeentsholongwane ezifana nokungunda kunye neebhaktheriya, kwaye inokubangelwa kukwahlulwa kakubi kwepeyinti namanzi, kodwa ukusetyenziswa kwe-paint mist coagulants akuyi kuvelisa ivumba elicaphukisayo, kwaye uninzi lwe-paint mist coagulants zongezwa kwiiarhente zokulwa neentsholongwane.

Izinto ezichaphazela isiphumo se-paint mist flocculant

(1) Iintlobo zepeyinti. Nangona kungekho nxu lumano lufunyenweyo phakathi kohlobo lwe-resin kunye nesiphumo sokusetyenziswa, kuyaziwa ukuba ii-coagulants ze-paint mist ziyayiqonda i-polarity ye-resin. Ii-coagulants ze-paint mist ze-polarity ezahlukeneyo kunye ne-hydrophilicity kufuneka zisetyenziswe ngokulandelelana kwiipeyinti ze-polarity ezahlukeneyo.

(2) Ixabiso le-PH okanye i-alkalinity. Kuyaziwa ukuba i-alkalinity efanelekileyo okanye i-pH inegalelo ekukhutshweni kwepeyinti. Ixabiso le-pH liphezulu kakhulu, ipeyinti iyatshatyalaliswa ukuze amasuntswana azinzileyo asasazeke emanzini anzima ukuwaqubha, aphantsi kakhulu awanakutshatyalaliswa ngokupheleleyo. Ulawulo oluqhelekileyo yi-9.0, kwaye ulawulo lubaluleke kakhulu ekusebenzeni kwamanzi ajikelezayo.

(3) inkqubo yebhokisi yokupenda kunye nenkqubo ye-slag yokupenda emva konyango. Inkqubo yegumbi lokupenda isitshizi esetyenziswa rhoqo ibandakanya uhlobo lokuhlamba, uhlobo lwekhethini lamanzi, uhlobo lokuhlamba isitshizi samanzi, uhlobo lwe-water swirl, uhlobo lweVenturi kunye nezinye iintlobo, kwaye iindlela zokususa i-slag ezisetyenziswa rhoqo ziquka ipleyiti yokukrazula, uhlobo lwe-centrifugal, njl. Inkqubo yegumbi lokupenda isitshizi, izinga lokuhamba kwamanzi ajikelezayo, isantya, kunye nendlela yokususa i-slag ziya kuchaphazela isiphumo sokusetyenziswa.

(4) izinto ezibangela iikhemikhali zamanzi. Ukungcola emanzini, njengobunzima, kuya kuchaphazela ubungakanani bamasuntswana okusasazeka kwepeyinti, ngaloo ndlela kuchaphazele ukulahleka kwe-viscosity, ngoko ke ubunzima kufuneka bube buncinci kangangoko. Ukungcola okufakwe kwinkqubo yokupeyinta ngokutshiza, njengee-solvents, ingakumbi ii-solvents ezingezizo ii-polar, kunokunciphisa kakhulu amandla okufunxa amanzi kwi-fog yokupenda.

(5) Indlela yokulinganisa kunye nokulinganisa i-paint mist coagulant. Ukuba i-dosage incinci kakhulu, i-condensation effect ayifanelekanga, kwaye ukuba inkulu kakhulu, ine-dispersion effect kwaye ayivelisi i-condensation. Iinkqubo ezahlukeneyo zokufunxa ipeyinti ye-spray booth zifuna iindlela ezahlukeneyo ezifanelekileyo zokulinganisa, ekufuneka zihlolwe kwaye zichongwe xa zisetyenziswa ngokwenene.

(6) Izinto ezibangela iintsholongwane. Uxinzelelo lwezinto eziphilayo emanzini ajikelezayo luphezulu kakhulu, kwaye iimeko zokusebenza kwamanzi ajikelezayo zifanelekile ekuzaleni nasekukhuleni kweentsholongwane. Ukuba azilawulwa ngononophelo, ukuzala kweentsholongwane kuya kuba nefuthe elibi ekusetyenzisweni kwee-coagulants ze-paint mist. Ii-arhente ezibulala iintsholongwane okanye iintsholongwane kufuneka zongezwe rhoqo xa ubushushu buphezulu.
