Ukuhlanzwa Okuphelele Kunye Neukuthinteka Kwemithambo Kusenqumeni Yezindustria Zokusebenza Ngokuphelele

Ukufa Kwemikhawulo Yokubhala Ngamazibuko Emaphethini, Emakhaya, Kunye Namasithakodwe Amanzi

Amakhawulo okubhala ngamazibuko ayathinta kahle uma ayabhekwa kumizimbi emihle yokuqonda njengezindlu zokulima, izindawo zokugcina amandla, kunye nezindawo zokuhlamba emhlabeni. Amakhawulo amaningi aqala ukubonisa izinkinga ngeminyaka emibili nesikumbi. Izinkambu ezincinci ziyadlula ngemva kwalokho, kuzokwenzeka ukuthi amanzi azofika phansi kwazo, okuyenza ukuthi kubhaleke isilungu, ukuthinteka kwemithambo kusuka kwezindawo zokubhala, futhi ekupheleni kuyathinta ubunzima bezindawo zokusebenza. Uma lezi zinkinga ziyagcina, izindawo zokusebenza zingadinga ukuthi zifuneleke ukuze zibhalwe kabusha. Ngokwesikhathi esidedile, ngokwesayensi yasePonemon Institute esithi ngo-2023, umthwalo wokuphatha nokuthinteka kwemithambo kuyisikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sokuthi kubhishwa isikhundla sok......

Ukuthi ukufutha kwe-powder yaselectrostatic kufikisa ukulondoloza kakhulu ngokusebenzisa ukubeka kwefilmi ngokulinganisana nokuhlanganiswa kwe-thermoset

Umsebenzi wokufaka umthwalo wokugcina ngokuphakanyiswa kwamandla wokugcina kuyisibonelo sokuthi sisebenzisa isistimu yekhuluma emibili yokuhlinzekisa lezi zinkinga. Indima yesokuqala iyasebenza lapho amaparticile atholakala ngokuphakanyiswa kwamandla ayagcina ngokulinganayo phakathi kwe-60 ne-120 microns. Ngaphandle kwezindlela zokufaka ezihlelwe ngamanzi, akukho mazwi okungafanele ukuthi aphakanyiswe, ukuthi aphakanyiswe kancane noma lezi zidinga zokuthi zingafanele ukuthi zingabili kakhulu, okungaba yinkomo yokubeka kwezinye izindawo. Emva kwalokho kufika indima yesibili lapho umoya ophakanyisiwe uyavula into ethiwa ngokuthi yisibonelo sokuhlinzekisa kwe-thermoset. Ngokuchaza kahle, amamolekyuli we-polymer ayadlala ngokuhlanganisa ngokuthi ayalanga kusenzo lokuthi yilokho okuphakeme kakhulu okuzokhlinza amachemikhali. Amalaboratori okuzimela abonisa ukuthi isitayile esifakwe ngendlela leyo singathola izikhathi eziningi kune-3000 emasikhabeni ekuphakanyiseni kwe-salt spray ngokwesiqephu se-ASTM, okuyisibonelo sokuthi sibhili ngokuphakeme kunezifaka zokuhlelwa ngamanzi. Lokho okukhombisa ukuthi kuyisibonelo sokuthi kuyaphakama kakhulu kukhona ukuthi kuvuleka kokukhlinza kwezinye izindawo ngaphansi kwesikhebe futhi kuyasebenza ngokuthi kuyaphakama kakhulu ukuthi kuboneke kwezinye izindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zokuthi kuyaphakama kakhulu kwezindawo zok......

Ukuthintana Kwemali Yokusebenza Nokuthuthukisa Kwemisebenzi Yokuqala Ngokusebenzisa Ukuphakamisa Kwemithwalo Yenziwe Ngokusebenzisa Isikhathi Sokugcina

Umsebenzi wokuphakamisa kwemithwalo yenziwe ngokusebenzisa isikhathi sokugcina uyathinta izindlela zokusebenza zokugcina kwezindustria ngokuphatha ngokuphelele indlela okwenza ngayo emkhakheni. Izinhlangano zezinkampani zokusebenza ngokusebenzisa izinkampani zokugcina ziyadinga izinyathelo eziningi kanye nezinyathelo zokugcina phakathi, izinyathelo zokugcina phakathi, kanye nezinyathelo eziningi zokugcina emizuzwini. Ukuphakamisa kwemithwalo akufuni lezi zinyathelo zonke ngoba kuyagcina kabusha ngonye kuphela emizuzwini. Lokhu kususa izikhathi ezingaphezu kwe-30% kuya kwe-50% yezikhathi zokusebenza zonke ngokubhalwa kwezindustria. Abamangisi bemkhakhe bakhuluma ngokuthuthukisa ngaphezu kwe-40% kwespeed yokusebenza xa bavuka ukusebenzisa ukuphakamisa kwemithwalo, kanye nabona ukuthi kubhishwa ngaphezu kwe-60% izikhathi zokuhlela iziphene. Lokhu kungani? Lezi zikothi zokugcina ngokuphatha kwezinsimbi ziyaphila ngokuzenzakalelayo izinkinga ezingaphansi kwezinkampani zokugcina njengezinkampani zokugcina, izinyathelo zokugcina, kanye nokudinga kokuhlela kabusha okwenziwa ngokufika kwamadoda amaningi emthwalo wokugcina.

Ukuphula kwezindlela zokusebenza, ukusebenza kabusha, nokusebenza kwezindawo eziningi zokukhanya ngokulinganisela nezindlela zokubhisha ezingaphansi kwezinto ezingavamile

Umgcino wendlela uyakhiqiza izindawo zokuvula kwezilungu kanye nezindlela zokuhlanza ezingathandabuzeki—ukuphula ukusetshenziswa kwamandla ngemitha yezigaba ngasinye. Ukusebenzisa izinkampani zokusebenza ngokuzenzakalelayo kusinika ukuthi isikhathi sokubhisha sibe sibonakalise kuzo zonke izindlela ezihlukene apho izinkampani zokubhisha ezingaphansi zihlukana ngokungafanele, okufaka kakhulu ukuphula ukusebenza ngokwesibonelo kanye nokuthintana.

Ukubhisha kungaphezu kwezimali kanye nokuthintana kwe-95–98% yokuthintana: ukuthintana kwezinto kanye nokugcinwa kwezindawo zokubhisha

Kodwa izindawo zokugcina zokuphakanyiswa kuzoba zihambisana nezinkulungwane zemithambo yomthwalo kusuka kumaphuzu emithambo yomthwalo, bafika kumaphuzu emithambo yomthwalo ngokungafani noko kubhekwa njengokuthi kuyabona kakhulu. Umphumela? Kungenani kune-2% yokugcina kwemithambo yomthwalo ngokusebenza. Ngokusebenza kahle kwezindlela zokuhambisa, izigidi ziyahlala zihlukanisa ukusetshenziswa kwemithambo yomthwalo phakathi kwe-20% kunye ne-40% ngonyaka. Okushiywa ngasinye akuyiyo kuphela ukugcina. Izinhlelo zokubuyisa ezintsha zinokubuyisa kakhulu kune-95% yokugcina kwe-powder ngokushesha, futhi liya kubuyiselwa ngokushesha ekuprodukweni. Akukho inkinga yokubuyisa amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba okufaka amathuba......

Ukubhalwa kwezinhlelo zokusebenza nokuthi kuyasebenza kahle kwezinhlelo zokuphatha izinto ngokuphelele

Izinhlelo zokusebenza zama-EPA VOC nezinhlelo zokuvimbela ezihlukaniswe—ikakhulu emaphakathi kwezinhlelo zokusebenza zezibalo zemoto kunye nezinhlelo zokusebenza zemithambo yomthwalo

Imithwalo ye-EPA ngemibono yezinto ezihlukahluka ngokuphakeme kuzoba zinamandla nganye nganye, ikakhulu kubazikhiphi abasebenza emisebenzini yezinyathelo zemoto apho lezi zisombululo zizoba zingaphansi kwezinye. Ukufutha ngokusebenzisa umthwalo wokufutha ngokusebenzisa umthwalo wokugcina amandla (electrostatic) uyavula konke lezi zimbhalo zezinkampani zokufutha ngokuphelele. Sibhala ngokungabi nani na ngokuphelele ngokulingana nokufutha okusebenzisa amanzi okufutha okuyisikhathi esihlukile apho kufuneka kusetyenziswa izinkampani zokulungisa ukungcoliswa okunamandla. Kumaqondo ozokuba nezinkampani zokulungisa ukungcoliswa, lokhu kwenza umphumela omkhulu. Abasemakhaya abaningi abanamandla manje abayofuna imisebenzi yokwenza izinto ngendlela engekhoyo, ngakho-ke amaqondo abasemakhaya abaswitching ku-ukufutha ngokusebenzisa umthwalo wokufutha ngokusebenzisa umthwalo wokugcina amandla (powder coating) abanakwazi ukuthatha ama-$740,000 ngonyaka ngokuvula izifundo zokufuna ngokwesikhathi esihlukile ngokwesicabanga sika-Ponemon esithile ngonyaka odlule. Ngaphezu kwalokho, njengoba lezi zinkampani azikho zizinto ezingahlukeni ngokuphakeme kwezinye, izindawo zokwenza izinto azikho zizoba ziyasebenzisa izincwadi eziningi ezinamandla okuhlanganiswa ngokwesiqondiso se-Title V se-Clean Air Act.

Ukuvula izinto ezingahlukeni ngokuphakeme kwezinye: akukho ukufuna kwezinkampani zokuvula izinto ezingahlukeni ngokuphakeme kwezinye noma ukubhala izincwadi zokufunda ngokwesiqondiso se-HAPs

Ukuguqula kumateriala esebenzisa isolvanti ku-thermoset polymer resins kwisistimu yokubhisha ngamaphutha kususa ngokuphelele indlela yokusebenzisa izinhlelo zokubuyela izinto ezingavumelekile. Sizobhekisa lokhu kusukela: izindlela zokubhisha ngamalithu okwesikhathi esihlukene zidala ngama-3 kuze kube ama-5 amathoni we-solvent sludge esihlukene ngomwe ngisho noma yilokho kusuka kumkhakha wokuproducwa umnye. Lokhu kufanele kubuyiselwe ngendlela eyodwa futhi kufanele kwenziwe izibhalo zonke zokuhlanganisa ngaphandle kwe-EPA. Kodwa ngamakhambu okubhisha ngamaphutha, abaprofayili bafumana kabusha ngama-98 amaphesenti kwezinto ezibhishelwe ngokungafanele. Lokhu kunciphisa ukubhishelwa kwezinto ezingavumelekile ngama-95 amaphesenti futhi kususa inkinga yokubhabha izilwanyana ezingavumelekile zokuhamba kwezinyawo. Iziphrofithi zokugcinwa kwelanga ziyinkimbinkimbi kakhulu. Abaprofayili bakhula ngokuphelele izinto ozokubhala kwezinyawo nezindawo zokugcina izinto, kodwa bafika ekupheleni kwezinhlelo zabo zokugcinwa kwelanga (ESG). Futhi asikwazi ukuzibiza ukuthi kunezimpikiswano zokugcina izinto ezingavumelekile. Abaprofayili bakhula ngama-30 kuze kube ama-40 amaphesenti kwezindlela zokugcina izinto ezingavumelekile zokubhishelwa uma bavula kule ndlela.

Ukuhlinywa Kwempilo Yezinhlelo Zokusebenza: Iziphakamiso Zokubonisa Ukuthi Kuyisiphi Isikhundla Sokuziphatha

Kumizini yezinsiza eziningi, ukufutha kwe-powder yokugcina ngokuphakanyiswa kwemithambo kubonisa iziphumo eziphelele kunezinye izinketho. Faka umzekelo emaphoyinti wezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kwezinye zezimali ezingaphakathi kweziny......
