Kungani i-powder yokugcina iyisibonelo esihlukileyo esihle kakhulu kumhlaba kuliquids yokugcina?

Ukungena kwe-VOC: Sizinga sengathi ukubhisha ngamapowda kususa ukuphutha kwesolvent kwezinye zezinye zemithombo yezinye zezinye

Umbuzo we-VOC kumaqondiso ema-liquid: Izinkinga zokugcina ubuso nobukhemphele bukuhlanganisa

Kodwa kusukela kwezinkotho zokufihla ezisebenzisa amasolventi, kubhala i-Volatile Organic Compounds (VOCs) emhlabeni. Lezi zikhemikali ziyizinkinga kuzo zonke izinto, ngempela. Zifutha isipho sasezulwini sithi futhi zinokubangela izinkinga zonke ezingaphansi kuka-kuhlala kwezinye izinto – khumbula ukungafihla kahle, ukungabona kahle kwesibonelo, futhi ukuthi kunezidingo eziphezulu zokuthi ubuhlungu bezincwadi zisukela kulezi zikhemikali. Isikhundla sesilika sokufihla esikhulu siyisiphakathi esikhulu lamanje, esibonakalisa ukuthi kuyisikhundla esisodwa nge-40 percent yezonke izinkotho zokubhala emhlabeni ngokusho kwe-US Environmental Protection Agency kusukela ngo-2023. Amagovernment ayabona lezinkinga futhi abegcina ukuphatha ngokuphambili lezinkotho. I-EU ngokusebenzisa i-REACH program yabo futhi amaregulatori ase-America kwe-EPA bakhupha isibalo sokuthi yini esihle kakhulu kwezinkotho zokubhala. I-California ibhala kabanzi ngokuthi i-Air Resources Board yabo ibhala isilinganiso esiphakeme ngaphezu kwe-2.1 pounds per gallon. Izimpahla ezingavumelekiyo zokuthi zingavumelekiyo ziyathola izinkambo ezingabi ngenani – sizibona ukuthi kunezinkambo ezingaba yizigidi ezenkulu zama-dollars ezingaba yizigidi ezenkulu zama-dollars ngokusho kwe-research ephathelwe yase-Ponemon Institute. Ngakho ke akuyiyo kuphela ukwenza lokho okuhle kwezinhloso zasezulwini kuphela; izimpahla zingazimiseka ukuzibiza lezinkinga uma zifuna ukuba zibe phakade.

Ukusebenzisa kwesikhali sokufaka isilwane sokufaka esingasolwa ngokuphelele kusiza ukuthi kubekwe ngokuphelele ngaphandle kwe-VOC

Ukufutha ngokwepowder akakheli izolventi zonke, ngakho-ke akukho nokuthi kubhaleka kwe-VOC noma kuhlehlwa umfanekiso. Le ndlela yasebenza ngokuthi sibhala amaphakathi amancane atholakala ngokwelektriki kumaphepha emetalu okwenzelwe ukuthi aqondwe. Lezi zikhathi zihlanya kahle futhi zihlukana uma zihlukana ngokwekhaya ngaphandle kokuthi kubhekwe izinkampani zokuchitha noma kubhekwe izinkinga zokuhlukana. Ngokulandela i-Finishing & Coating Magazine, abasemthengisi bafuna imali ngoba babengayidingi izisifunda sezivumbi eziningi noma izinkampani zokuchitha amanzi okuzosuka kwezilungiselelo zokufutha ngamanzi. Izifundo ezenziwe ngokwesibonelo esingaphandle kubonisa ukuthi iziphepha ezifuthwe ngokwepowder zihlukana izigrama zero ngaliliter we-VOC, ngakho-ke izilungiselelo zokufutha ngamanzi zihlukana izigrama 250 ku-500 ngaliliter ngokulandela ukufunda kwe-ScienceDirect kusukela ngo-2023. Lokhu kwenza ukufutha ngokwepowder kube yinto enenhle kakhulu kumhlaba kodwa kwenza nezimo zokusebenza ezinhle kakhulu emizini lapho abantu baphatha iminyaka yabo bafutha izinto.

Imfucuza Eseduze Ne-Zero: Ukusetshenziswa Kwezinto Eziningi Nokuphinda Kusetshenziswe Ngokweqile

ukusebenza kahle kokudluliswa kwama-97% nokusetshenziswa kabusha kwe-closed-loop ye-coating powder

Ukusebenza kahle kokudluliswa kwe-powder yokumboza kufinyelela kuma-97%, ngakho-ke iningi lalokho okufafazwayo empeleni kunamathela lapho kudingeka khona. Ngenxa yamandla kagesi, le mpuphu ihlala ngokunembile ngisho nasezimweni ezinzima. Lokho okungamatheki kuhlala kuhlanzekile futhi kusebenziseka ngoba akungcoliswa lapho kusetshenziswa. Izikhungo eziningi manje zisebenzisa izinhlelo zokubuyisela izinto eziphambili njengezivunguvungu nama-filter cartridge ukuze zithathe izinsalela zempuphu ngokushesha. Lokhu kubenza bakwazi ukuxuba izinto ezivuselelwe zibe amaqoqo amasha cishe ngesigamu senani lokuqala ngaphandle kokuphazamisa ukubukeka kokugcina, imibala ihlale injalo, nezingubo zihlale isikhathi eside. Yonke le nqubo inciphisa inani lezinto ezintsha ezidingwa izinkampani unyaka ngamunye cishe ngo-40% emigqeni yazo yokukhiqiza, futhi igcina izinto ezilahliwe zingagcini ezindaweni zokulahla udoti lapho zingahlala khona phakade.

Amakholi Amanzi vs. Amakholi Okuphutha: Isiphelo Sokusebenza 30–50% vs. Isiphelo Esingaphezu kuka-3%

Kodwa kusukela kumakholi okugcina amanzi, akukho ukuphikisana nokuthi bakhel’ umsitha omkhulu. Khumbula konke lokhu kholi okuhamba kumoya, lezi zikhathi ezinkulu zokubhala kuzo zonke izindawo, futhi lezi zikhathi ezinkulu zokubhala okungatholakali. Sibizwa ngokuthi sithola kusukela ku-30% ku-50% kwemithombo, futhi yizinye zezinto ezingatholakali ziyizinto ezenza isifo esingahleli ekuthunyenzweni, okufanele kuthunyenzwe ngendlela eyodwa xa kuthunyenzwa. Ukugcina amaphutha kuyasiza kakhulu. Umthwalo wamaphutha uphansi kuka-3% ngoba kunezinkinga ezinkulu zokubhala okungatholakali okungatholakali kuzo zonke, futhi akukho kholi kulezi zinkinga. Bheka ukuthi kusho kanjani ngo-2023 lapho abaprosesha beziqephu sezinsiza zezimoto zabalisa imisebenzi yabo yokugcina ngokugcina amaphutha. Indawo enye yaye yasinda ama-$740k ngonyaka kumalini wezinto ezenza isifo esingahleli ekuthunyenzweni, futhi yasebenza ngenkulu yezinkinga ezingafanele kuthunyenzwa ngokuthunyenzwa kwezinto ezenza isifo esingahleli kanye nokuthi kubhalwe ngokucacile. Ubuchazimbo phakathi kwezimbili lezi zindlela? Kuyisibonelo sokuthi imali ibhala futhi uMama Ntando uyabheka.

Lezinyathelo zokusebenza lezi kusenza ukuthi ipowda yokubhisha yisici esisodwa kuphela sokugcina esihlukanisiwe ngokwesifundo esikhulu esisodwa ngokuphelele nendima yokungena kwemithombo yezinsizakalo nezindlela zokusebenza ezinamandla.

Ukunciphisa Ukuphatha Kwesikhathi Sokusebenza Kwezinhloso Zemvelo: I-Energy, Ukubhishwa, Nokuzimiswa Kwemibono Yasezweni

Ukunciphisa Ukusebenzisa I-Energy Yokubhisha Nokungabikho Kwamathambo Amakhulu Kupowda Yokubhisha

Amakholi okuphatha kufuneka amandla angaphezu kwe-20 kuze kube ngu-30 percent engaphansi kokuphatha kwamakhombe amahle asebenzayo. Kusebenza kwezinye izintemperetsha ezincane futhi, ngokuvamile kwi-150 kuze kube ngu-200 degrees Celsius, ngaphandle kwezinhlobo zezinkole zokuphatha eziphatha kwi-200 kuze kube ngu-250, futhi zisindwa kwezinkole zokuphatha kuzo. Uma sibhekisela ukuthi lezi zinkole zokuphatha zezindustria ezingaphezulu ziyathatha amandla angaphezu kwe-40% yonke amandla esebenziswayo kumisebenzi yokuphatha, ukunciphisa leli amandla liyagcina ngqo kunciphisa kwezinkulungwane zokugcina kusonke isikhundla sokuphatha. Okukhomba ukuthi amakholi ayisodwa kakhulu kukuthi izinhlobo zezinsuku zezinkole zokuphatha ezingu-20 zingasivumeli izinto ezingavumelekile njengokuthi kusilika, umkhosi, umkhosi wokubhala noma lezi zinye izinkole zezimithi ezingavumelekile ezinokuthinta umhlaba namanzi ngamashumi amaningi. Lokhu kusho ukuthi abasebenzi bahlukumeza ukusebenzisa izinto ezingavumelekile zokuphatha kwezinkole zokuphatha ezihle, futhi bahlukumeza ukusebenzisa izinto ezingavumelekile zokuphatha kwezinkole zokuphatha ezihle. Futhi kukho isibonelo esinye: amakholi ayisodwa kakhulu ukuthi asizange sisebenzise izinkole zezinkole zokuphatha ezinokuthinta umhlaba, okunciphisa izinkinga zokuthinta umhlaba kusonke kusukela kusenzo kuze kube kusenqanawa.

Ukuhlanganisa ukuzimela kwe-EPA, i-EU REACH, ne-CARB Ngokusebenzisa i-Coating Powder

Izinkulungwane zokufutha zinavoc ezingakhi ekhulu futhi azinametali emhlophe, okuyisibonelo sokuthi ziyathandana ngokuzenzakalelayo nezinhlelo zokulawula izinsiza eziningi. Hlalani ngalesi simo: ngakumbi izinkulungwane zemithi yezindawo zokufutha ziyadinga izinkampani zokulawula ukuphuma kwamafutha, izinkampani zokubuyela izilwanyana, nokukhokha kwezinye izikhathi, kodwa izindawo zokufutha ngamaphutha ziyathola izivumelwano ngokushesha futhi zihlanganwa ngokungafanelekile. Ngokuchazwa kwezinhlelo zokulawula, izinguquko zika-2022 kwe-Harmonized System classification system zayenza isidingo esincane kwezinkulungwane zokufutha ngokuthi izinkulungwane ezingasetyenziswa noma ezingabuyiselwa ziyizinto zokugcina zokusebenza, akaze zibe yizinto eziphatha ngokuvamile. Okuyisibonelo sokuthi amakhampuni ayakwazi ukususa izinto abazisebenzisi ngaphandle kokuthi baphinde baphinde baphelela izinkinga eziningi. Kumaqembu othanda ukufikisa izinhlelo zokulawula zika-ESG futhi ukwakha izindlela zokusebenza ezizosha ngama-5 ama-nyaka, ukuguqula kwezinkulungwane zokufutha kuyenza umphela wokulawula ngokushesha. Akukho inkinga yokuthenga izinkampani eziningi noma ukuphatha izinhlelo zokuhlela.
