Kungani isikrini sokufaka ematsheni sibhekana nempilo yezindustria zokwenza izinto ngendlela enjengezinye?

Ukungakho Kwezinkampani Zezinye (VOC) Nezinhlelo Zokuphakwa Ezisemthwakathini

Ukucima izinkampani zezinye (VOCs) nezinhlelo zokuphakwa eziphulaphula amafutha (HAPs)

Ukumboza ngempuphu kususa lezo zinyibilikisi eziyingozi esizitholayo ekumbozeni oketshezi okuvamile ngoba kusebenzisa ama-polymer akhethekile agcina ukushisa angenawo nhlobo ama-VOC, amakhemikhali avundile, aziwa ngokudala intuthu engcolisayo nokwenza abantu bagule lapho bewaphefumula. Imidwebo evamile esekelwe kuma-solvent empeleni ikhipha izinto eziyingozi ezifana ne-benzene lapho isetshenziswa, kodwa izembozo ezinempuphu zinamathela ndawonye ngamakhemikhali ngaphandle kokukhulula umusi emoyeni. Ngokwe-Automotive Manufacturing Solutions emuva ngo-2023, ukushintshela ekufakeni i-powder coating kunciphisa ukukhipha ubuthi bezimboni njenge-formaldehyde cishe ngo-98% futhi kusalandela yonke leyo mithetho eqinile ye-EPA mayelana nekhwalithi yomoya. Ngaphezu kwalokho, njengoba lezi zembozo zingenayo imithi esebenzayo, asikho isingozi sokuthi amanzi angaphansi komhlaba angcoliswe ukuhlanza izinsalela zezinyibilikisi noma ukubhekana nodaka oludluleleyo kuyo yonke inqubo yokukhiqiza.

Ukuvikeleka okuqinile emsebenzini nokuhambisana nemithetho yezikhungo eziqaphela imvelo

Abakhiqizi abasebenzisa izembozo ze-powder babika izehlakalo zezempilo ezihlobene ne-solvent ezingaphansi ngo-34% ( Izixazululo Zokukhiqiza Izimoto , 2023), okuqhutshwa:

• Ukuqedwa kwezingozi zokugcina izinto ezingase zivuthe
• Isidingo esincishisiwe sokufaka izifonyo phakathi kwabasebenzisi
• Ukususa ama-isocyanate abangela umdlavuza ezindleleni zokuqeda

Le phrofayili yokuphepha yangempela yenza kube lula ukuhambisana nemikhawulo yokuchayeka kwamakhemikhali ye-OSHA kanye nama-ISO 14001 amaprothokholi okuphatha ezemvelo. Izikhungo zigwema ukukhokhwa kwezindleko ezibizayo zokulahlwa kwemfucuza eyingozi $740/ton for solvent sludge versus $120/ton for recyclable powder overspray ( Instituthi yePonemon , 2023) ngesikhathi esifanayo ekhombisa ukuphathwa kwemvelo okulinganisekayo kubacwaningi bamabhuku okusimeme.

Ukusetshenziswa Kwezinto Ezicishe Zibe Ziphelele Ngokuthola Izindleko Ezingaphezulu

Ukusetshenziswa kwe-electrostatic okwenza kube nokwenzeka ukuthi kusetshenziswe kabusha i-powder coating > 95%

Ukusebenzisa imithambo yemvelo yezinkulungwane iyabiza ngokupheleleyo ukusebenza kwezinto eziqondile kumsebenzi wokugcina emindeni. Uma ipowda ifakwa amandla, iyahlukana kuleli sikhundla esingasifakwanga amandla, okubonisa ukuthi izinto zonke ezihlakaziswa ziyaphela kuwo onke owenziwe ngokufanele. Ipowda eyengeziwe engezansi iyambelwa ngamathuba okubuyisela aphathelene noma yimuphi umkhondo wokuhlakaza okwenzekayo, njengoko kubhekwa kuma-cyclonic separators. Iyobuyiselwa iyagcina konke amaphuzu akhona futhi iyabuyiselwa ngokushesha kusistimu. Izinhlelo zezinkulungwane zokugcina zonke ziyasebenzisa ngokupheleleyo i-95% yepowda yabo, okuyisibonelo sokunakekela izinkulungwane zempilo zokugcina ezintsha, ngoba lezo zisebenzisa kuphela i-50% kanye noma ngaphezu kwalokho. Ngaphezu kokuthinta imali yokungena kwezinto ezingafakwanga, lezi zinhlelo zihlanganisa nokuthinteka kwemithambo eyincongolo ekuvuleni kwezilwanyana kusuka kwezinye izinto, futhi ziyabuyisa ukuthi wonke umbhalo ubuyiselwe ngokulinganayo ngaphandle kokuthatha izikhathi eziningi.

Ukuchaza kwezinto zokuziphatha: Ukunciphisa ukungena kwezinto ngokupheleleyo ngo-92% kwezinhlelo zokuhlanganisa izinto zomoto

Umprofesi wamaparts wezithakazela enkulu wamathuba lezi zifiltre ezimangalisayo kumalini yezokuproducwa eziphakathi kwezinye zisixhenxe, futhi emva kwezinsuku ezingu-18 babona okungahleli. Ukuhlukunyezwa kwabo kwezinkulungwane zokufaka kwezithakazela kushukuma ngama-92% ngonyaka, okusho ukuthi babephatha amathonsi angu-300 ngonyaka ngokuvamile kuzindawo zokugcina izinto ezingavumelekile. Iziphrofithi zezimali zabanikwa ngokubonakala kakhulu futhi, bakhetha ama-$1.2 million ngonyaka kuphela kuzimali nokususa izinto ezingavumelekile. Ngaphezu kwalokho, lokhu kucabanga kunciphisa ukuphakama kwabo kwe-carbon ngama-850 amathonsi we-CO2 ngonyaka ngoba badinga ukuproducwa kwezinto ezingafanele kakhulu. Ngakho-ke, kubonisa ukuthi ukufaka kwezithakazela kungahlanganiswa ngokuphelele nesikhundla sokuproducwa esingaphansi kwezinhlobo zokusebenza ngokuphelele, ngaphandle kokuchitha isikhathi sokuproducwa noma ubukhulu bezinhlobo zezinto zokugcina.

Ukufaka Kwezithakazela Okuphelele Kwezimali Zomoya Nokunciphisa Ukuphakama Kwemizwi Yezinhlobo Zokusebenza

Izinsuku zokufaka zingaphansi, ukudinga kwezomoya kungaphansi, nokunciphisa ukuphakama kwe-CO2 ngalokho okufakwa

Uma kuqhathaniswa nezindlela ezisekelwe ku-solvent, ukumbozwa kwempuphu kuvumela izikhathi zokupholisa ezisheshayo, okusika ukusetshenziswa kwamandla okushisa ngesikhathi sokukhiqiza cishe ngamaphesenti angu-30 kuya kwangu-50 Ukwakheka kwamakhemikhali okusekela izimpushana zanamuhla kuzenza zikwazi ukubopha ngokuphelele emazingeni okushisa aphansi kakhulu, ngokuvamile aphakathi kuka-120 no-150 degrees Celsius esikhundleni sama-180 kuya ku-200 odingekayo kumapende avamile, ngakho ama-oven akudingeki asebenze kanzima. Okwenza le nqubo ikhetheke ukuthi incibilika ngokushesha kangakanani futhi igeleze kuyo yonke indawo, iqede umsebenzi ngemizuzu embalwa nje kunokuba kudingeke ukuba kubhakwe isikhathi eside, okuyinto eyenza kube nzima ukuvikela indawo yokumboza. Abanye abakhiqizi manje basebenzisa ukukhanya kwe-infrared noma kwe-UV ukuze basheshise izinto nakakhulu, bagxile ekushiseni lapho kudingeka khona ngaphandle kokuchitha amandla ukufudumeza amakamelo agcwele. Ukulahla lezo zinhlelo ezibizayo zokulawula ama-VOC kusindisa namandla engeziwe. Sekukonke, lezi zinguquko zinganciphisa ukukhishwa kwe-carbon ngamaphesenti angaphezu kuka-40 ngomkhiqizo ngamunye ophelile, futhi zisakwazi ukugcina izinga elifanayo lokuqina nokusebenza esilindele kuma-coatings asezingeni eliphakeme.

Ukwenza izitifiketi zokusimama kanye nokuhlukaniswa kwemakethe

Ukuhambisana ngqo ne-ISO 14001, ama-leed v4.1 MR credits, ne-EPA Safer Choice

Ukumboza okungu-powder kusekela ukuhambisana nezinhlaka eziholayo zokusimama, kunikeza abakhiqizi indlela eyisihluthulelo yokuqinisekisa. Ukwakheka kwayo okungenawo ama-VOC nokunciphisa imfucuza eyingozi kuhambisana ngokuyisisekelo nezidingo zokuphathwa kwemvelo ze-ISO 14001. Izikhungo zifanelekile ukuthola ama-lead v4.1 Materials and Resources (MR) credits ngenxa:

• Amandla okuqukethwe kabusha (> 95% wokubuyiselwa kokugcoba ngokweqile)
• Ukukhishwa okuphansi kakhulu ngesikhathi sokusetshenziswa
• Ukunciphisa ukusetshenziswa kwamandla ngesikhathi sokupholisa

Uchemistry wena futhi uyafikilela kwezindlela zokuziphatha zika-EPA Safer Choice ngokungafani noma kubonakala kahle kubantu nokwakhiwa kwesibonelo. Umsebenzi wokuhlola ngaphandle kwezindaba ubonisa ukuthi abasebenzisi abaqinisekisiwe bavuma ukuthi ubuhle bokubhukuda kubabuyi abaneminqumo yezinsizakaliso, bakhulula ngokuphakeme kwe-38%. Ngokufikilela kulezi ziqinisekiso, izimpahla ziyagcina ukuthi zihlale zifanele kwezimpendulo zokugcinwa ngokuvamile ukuze zibe nesibonelo esihle—kubona izicontract ezingaphansi kwezinsizakaliso ezinomthelela kwezinsizakaliso, kusukela ku-vehicles eziphambili (EV) kuya kwezinsizakaliso zokwakhiwa ngokuphelele.
