Kungani ukuphakanyiswa kwe-paint powder coating kusebenzwa kakhulu ekwenzeni kwamaparts we-automotive

Kungani abasebenzisi base-automotive baphila bakhetha ukuphakanyiswa kwe-paint powder coating

Ukuphakamisa kwempapu yekholora kwenziwe yindlela eyodwa yokugcina amapharti we-automotive, futhi izizathu ziyagcina ngaphezulu kokufana. Impapu engafanele iyachazwa, ibhishwa kumapharti wemetal ephakanyiswe, emva koko iyasuswa emveni. Le ndlela iyadala isilayi esihlukene esingabona ukuchitha, amakhemikhali, nokubonwa kwe-UV. Amapharti we-automotive ayabona isalt yesimini, isandla, isikhatshana sesengini, isandla seshibhishi, nokwesibili kwezinsuku. Isilayi esingavumele kahle sisivumelano sokubuyela futhi sibeka isibonelo sesibindi. Ukuphakamisa kwempapu kuvumela isilayi eside, esihlukene ngaphandle kwezinkqubo. Lokhu kubalulekile kuma-bumper, ama-bracket, ama-wheel, ama-suspension arm, ama-battery tray, kanye nezinqubo zezindawo zokugcina ezincane. Kuvumela futhi kuma-plant ozinconywa ukuncima izinkqubo zokuhlanza kwe-volatile organic compound. Le teknoloji iyahambisana nendustria ngoba iyahlukene kubalulekile kwezinhlobo zokugcina, ukubonwa, kanye nezinhlobo zokusebenza kwezinsiza zokugcina.

Ukubaluleka nokukhulula ukuchitha kwezindawo zokugcina ezincane kanye nezindawo zokugcina ngaphandle

Izinqubo zezimoto zihlala kumizimba emhlophe. Umkhakha wokulawula ungathola ukuthi kubhekwe ngamaphambili noma kubhekwe ngamafutha amancane. Umkhakha wokugcina ubungo bengqondo ungathola ukuthi kubhekwe ngamafutha amancane noma kubhekwe ngamakhemikhali asebholweni. Umkhakha wokuphatha ungathola ukuthi kubhekwe ngamafutha amancane wokuphatha noma kubhekwe ngamakhemikhali okuphatha. Ukuphatha ngamapowda kusebenza kahle lapha ngoba ifilm ekuqaleni yisifunda esibonakalisayo kanye nokubondwa kahle. Ukuphatha kwangaphambili kuyisibopho. Ukuphatha kwe-phosphate noma kwe-zirconium kusobala umsindo wokuphatha kwe-steel noma kwe-aluminum ukuthi kubonde kahle. Uma akukho lokhu, ukuphatha kwe-powda okuhle kakhulu kungathola ukuthi kubonde kahle. Ukuphatha kwe-salt spray ngokwesiqephu sika-ASTM B117 kuyisibalo esibalulekile, futhi iziqephu zezimoto ziyasiza ukuthi zilinde izikhathi eziningi. I-SAE International ishuma iziqephu zokuphatha okusiza abasebenzi bokubanga ukuthi bahlale kubonakalisana nezinto. Ukuphatha kwe-powda kungatholakala ukuthi kubheke kumthetho wokubheka, ngakho-ke izinqubo ozikhubaza noma ozibheka azingathola ukuthi zibhaka kahle. Lokhu kubhekwa kahle phakathi kokuphatha kwe-hardness noma kwe-flexibility, ngakho-ke ukuphatha kwe-powda kubhekwa kuzinkambo eziningi zezinto zokubheka noma zezinto zokubheka.

Ukuphatha Ngokwelektrostatiki Kujabula Ukuhlukunyezwa Noma Ukuphatha

Ukusebenzisa i-electrostatics yisibonelo sokusebenza kwe-powder coating. I-spray gun iyabeka i-charge electrical emaqhina amancane. I-part e-grounded iyathatha lezi qhina, okuyakhula ukusebenza kwe-transfer. Ukusukela kwe-overspray kungakwaziwa ukubuyiselwa futhi ukusebenziswa kabusha, futhi kungenzeka ukubuyiselwa kwi-feed. Ukusukela kwe-liquid paint overspray akakwaziwa ukubuyiselwa ngendlela ethile. Lokhu kunciphisa ukuphakanyiswa kwezinto zokusebenza futhi ukuphakanyiswa kwezinto ezihlukene. I-U.S. Environmental Protection Agency ibonise ukuthi i-powder coatings ingakunciphisa i-volatile organic compound emissions kungezinye i-liquid coatings ezinamaphutha. Ukunciphisa ukusukela kungahlela ukuncamuka kwezinkinga zokufakwa kwe-air permits futhi ukunciphisa izindleko zokulandela izimpendulo. Kunezidingo. I-powder inqubuzana yokucura, ngakho-ke izinto ezinomthwalo wokucura azikweli. Ukuguqula umbala kubude futhi kudinga ukuchitha kahle. Izifunda ezincinci zokuhlelisa zingaba zinkulu kunezinye i-liquid systems. Ngaphezu kwezinye iziqephu zezinhloso zokugcina ezingaphansi kwezinhloso zokugcina, oku kungahleli kubalulekile.

Ukuchaza Ukuchitha Kwemithambo Kwe-Automotive Ngokuphinda Ngokuchitha Kwemithambo Ngokusebenzisa Amaphetha

Ithabuli elandelayo isebenzisa izikhundla zokubhekana ngokujwayelekile kwezindustria njenge-Powder Coating Institute, SAE, ne-EPA. Iziphumo zokwesha ziyaphendula kwezinhlobo zemithambo, ukuchitha kwakho, ukuthatha kwezinhlobo zemithambo, nokuzimisela kwezinkampani.

Izidata zibonisa ukuthi kukhona ukuthintana. Izinkemikali zomlilo zisobala kakhulu kumaqembu amancane okanye ama-heat sensitive applications. Ukuphakamisa kusobala kakhulu lapho ukuthintana, ukulinganiswa, nokuthintana nezinkemikali kuyisifundiswa. Abasemthengisi bamacine abayisebenzisa izinkemikali zomlilo kanye nokuphakamisa, bavuselela ukuphakamisa kumaqembu amakhulu wezinyathelo zemetalu futhi izinkemikali zomlilo kumabala amashumi amaningi noma izinyathelo zemphakathi.

Imfano yezokuphatha kwakhiwe ngokwempilo kusuka kumthengisi wamacine

Umthunywa wemoto emhlabathini waseMidwest wabika izibhakethi zesiyafulu nezincwadi zebhatari. Umqondo wokusebenza kwe-liquid osetshenziswa kwakhiwa ngokungafanele ngokuthi kubhishwa imali yamaphutha, ukuguqula amafiltela, nokungafanele kwezithunywa zokufaka isikhangeli kwezinto ezingaphansi kakhulu. Ukususa okungafanele kwezinhlobo zokusebenza nezinhlobo zokuphepha kwenza ukuthi kubhishwe imali. Isitolo sasusela izinhlobo zezinto eziningi kakhulu kumqondo wokusebenza kwe-powder nesistimu yokuqala kwezinyangani ezingu-5. Isikhombisi sesadata sasobala utempurete lwesoveni kwezinto, akasobali kuphela ukuthi kwezinyangani. Abaqondi bafindile indawo eyinkanana emva kwe-conveyor edge bayaqinisa isikhathi sokusebenza kwezinhlobo. Emva kokuguqula, izithunywa zokufaka isikhangeli zabaluleka kakhulu, futhi ukusebenza kwe-salt spray kubaluleka. Ukuguqula umbala kublack ku-gray kubhishwa imikhathi engaphezu kwe-liquid yekhanda yasezantsi, ngakho-ke ukusakha kwezinhlobo zokusebenza kushintsha ukuthi kuzamekwe izinhlobo ezingaphezu kwezinye. Ukuguqula kubaluleka ngoba izinhlobo ziyametali, izinhlobo zingaphezu kwezinye, futhi izinqumo zokufaka isikhangeli zibaluleka kakhulu. Lokhu nguqondo lwe-automotive powder coating, umqondo uyabonakalisa ukuthi ukuplanisa kubaluleka.

Ukuthuthukisa kwe-Supply Chain no-Hsinda kwezinhlobo zokufaka isikhangeli zemoto

Ukuqinisa ukuthi isiphetho sikhona kusukela emandleni okuphathelene nokuphatha amapowda nokuthuthukisa ngokwemisebenzi. I-Hsinda iyasebenzisa isistimu sokuphatha i-ERP esibhekise kumisipala waseYurophu, futhi isistimu sokuproducwa sesithili sokudijithali. Isikhundla sokuproducwa sasemva kweyishwa yezinkulungwane ezingu-5 zemipowda yokufutha, kubakho amapowda wepoksi, amapowda wepoksi ne-polyester, kanye namapowda amashumi amahlanu asezingeni lokusebenza. Isifazane sisebenzisa izilinye ezingu-8 zokuproducwa kanye nezilinye ezingu-3 zokuzama, noma kuyisikhundla sokuproducwa sasemva kweyishwa yezinkulungwane ezingu-500 ngomnyaka. Amakhredenshi akhiwe ku-ISO14001, CE, ISO9001, kanye ne-RoHS, futhi akhiwe amadatha wokuzama kwa-Florida kanye nokuzama okuhlinzekileyo. I-Hsinda inikeza umhlangozi wokuchaza ubunzima bokufutha, amarekodi okuzama ukulingana kwesikhati sokufutha, ukubhalisa izindleko, kanye nokuzama izilinye zokuproducwa. Isikhundla sokuthuthukisa (R&D) sithuthukisa izinto eziphatha izinkinga zomthwakazi wokuphatha. Uma abaphatha amapharti wemoto bafuna ukuguqula ukusebenzisa amapowda, i-Hsinda inikeza ubukhulu bekuproducwa, ukuphatha ubunzima, kanye nokuthuthukisa kwezindawo zokuthengisa okuyoba yinkimbinkimbi yokuproducwa okuphelele.
