Kufunika kwakukulu kwa ukadaulo wopaka utoto wothira kuwala kukuwonetsa phindu lalikulu la zachuma, zachilengedwe, komanso njira zogwiritsira ntchito UV-curing. Zopaka utoto wothira utoto wothira kuwala zimagwira bwino ntchito zitatuzi. Pamene ndalama zamagetsi zikupitirira kukwera, kufunikira kwa njira "zobiriwira" kudzapitirirabe mosalekeza pamene ogula akufuna zinthu zatsopano komanso zabwino komanso magwiridwe antchito.
Misika imapereka mphoto kumakampani omwe ali ndi luso lamakono ndipo amagwiritsa ntchito ukadaulo watsopano mwa kuphatikiza zabwino zaukadaulo izi muzinthu zawo ndi / njira zawo. Kupanga zinthu zabwino, zachangu komanso zotsika mtengo kudzapitilizabe kukhala njira yoyendetsera zinthu zatsopano. Cholinga cha nkhaniyi ndikuzindikira ndikuwerengera ubwino wa zophimba za ufa zophimbidwa ndi UV ndikuwonetsa kuti zophimba za ufa zophimbidwa ndi UV zimakwaniritsa vuto la "Zabwino, Zachangu komanso Zotsika Mtengo".
Zophimba za ufa zomwe zimachiritsidwa ndi UV
Zabwino = Zokhazikika
Mofulumira = Kugwiritsa ntchito mphamvu zochepa
Mtengo wotsika = Mtengo wokwera pamtengo wotsika
Chidule cha msika
Kugulitsa zophimba ufa zophimbidwa ndi UV kukuyembekezeka kukula osachepera atatu peresenti pachaka kwa zaka zitatu zikubwerazi, malinga ndi Radtech's February 2011, "Sinthani Ziwerengero za Msika wa UV/EB Kutengera Kafukufuku wa Msika." Zophimba ufa zophimbidwa ndi UV zilibe mankhwala osinthika. Phindu la chilengedwe ichi ndi chifukwa chachikulu cha kukula kumeneku komwe kukuyembekezeka.
Ogula akuyamba kuzindikira kwambiri za thanzi la chilengedwe. Mtengo wa mphamvu ukukhudza zisankho zogula, zomwe tsopano zimachokera pa kuwerengera komwe kumaphatikizapo kukhazikika, mphamvu ndi ndalama zonse za moyo wa chinthu. Zisankho zogula izi zili ndi zotsatirapo zake mmwamba ndi pansi pa unyolo wopereka ndi njira komanso m'mafakitale ndi m'misika. Akatswiri a zomangamanga, opanga mapulani, ofotokozera zinthu, othandizira ogula ndi oyang'anira makampani akufunafuna mwachangu zinthu ndi zipangizo zomwe zimakwaniritsa zofunikira zachilengedwe, kaya ndi zomwe zalamulidwa, monga CARB (California Air Resources Board), kapena mwaufulu, monga SFI (Sustainable Forest Initiative) kapena FSC (Forest Stewardship Council).
Kugwiritsa ntchito utoto wa UV
Masiku ano, chikhumbo cha zinthu zokhazikika komanso zatsopano chakula kwambiri kuposa kale lonse. Izi zapangitsa opanga ambiri opanga utoto wa ufa kupanga utoto wa zinthu zomwe sizinapangidwepo utoto wa ufa. Ntchito zatsopano zopangira utoto wa kutentha kochepa ndi ufa wothiridwa ndi UV zikupangidwa. Zipangizo zomalizitsa izi zikugwiritsidwa ntchito pazinthu zomwe zimakhudzidwa ndi kutentha monga fiberboard yapakatikati (MDF), mapulasitiki, zinthu zophatikizika ndi zinthu zina zomwe zasonkhanitsidwa kale.
Chophimba cha ufa chotsukidwa ndi UV ndi cholimba kwambiri, chomwe chimalola mapangidwe atsopano ndi kumalizitsa ndipo chingagwiritsidwe ntchito pamitundu yosiyanasiyana ya zinthu. Chophimba chimodzi chomwe chimagwiritsidwa ntchito kwambiri ndi chophimba cha ufa chotsukidwa ndi UV ndi MDF. MDF ndi chinthu chopangidwa ndi makampani opanga matabwa chomwe chimapezeka mosavuta. N'chosavuta kuchipanga, ndi cholimba ndipo chimagwiritsidwa ntchito m'mitundu yosiyanasiyana ya mipando m'masitolo ogulitsa kuphatikizapo malo ogulira zinthu ndi zinthu zina, malo ogwirira ntchito, chisamaliro chaumoyo ndi mipando yaofesi. Kumaliza kwa chophimba cha ufa chotsukidwa ndi UV kumatha kupitirira kwa pulasitiki ndi vinyl laminates, zophimba zamadzimadzi ndi zophimba za ufa wotentha.
Mapulasitiki ambiri amatha kumalizidwa ndi utoto wothira UV. Komabe, utoto wa UV umafunikira njira yokonzekera kuti apange pamwamba pa pulasitiki pogwiritsa ntchito electrostatic conductive. Kuti muwonetsetse kuti pamwamba pake pakugwirizana, pangafunikenso kuyatsa.
Zipangizo zomwe zasonkhanitsidwa kale zomwe zili ndi zinthu zomwe zimakhudzidwa ndi kutentha zikumalizidwa ndi zophimba za ufa zophimbidwa ndi UV. Zipangizozi zili ndi zigawo ndi zinthu zosiyanasiyana kuphatikizapo pulasitiki, zomangira za rabara, zigawo zamagetsi, ma gasket ndi mafuta odzola. Zipangizo zamkati ndi zinthuzi sizimawonongeka kapena kuwonongeka chifukwa cha zophimba za ufa zophimbidwa ndi UV zomwe zimakhala ndi kutentha kochepa komanso liwiro lokonza mwachangu.
Ukadaulo wokutira ufa wa UV
Dongosolo lodziwika bwino la utoto wothira ufa wa UV limafuna malo okwana masikweya mita 2,050 pansi pa chomera. Dongosolo lomaliza la solventborne lokhala ndi liwiro lofanana ndi mzere ndi kuchulukana kwake lili ndi malo opitilira masikweya mita 16,000. Poganizira mtengo wapakati wa lendi wa $6.50 pa sikweya mita pachaka, mtengo wa lendi wa pachaka wa UV-cure system ndi $13,300 ndi $104,000 pamakina omaliza a solventborne. Ndalama zomwe zasungidwa pachaka ndi $90,700. Chithunzi chomwe chili mu Chithunzi 1: Chithunzi cha Malo Opangira Zinthu Zapadera za UV-Cured Powder Coating vs. Solventborne Coating System, ndi chithunzi chosonyeza kusiyana kwa kukula pakati pa mapazi a makina odzaza ufa wa UV ndi makina omaliza a solventborne.
Magawo a Chithunzi 1
• Kukula kwa gawo—mamita 9 omalizidwa mbali zonse, 3/4″ wandiweyani
• Kuchulukana kwa mizere ndi liwiro lake kofanana
• Kumaliza kwa 3D part single pass
• Malizitsani kupanga filimu
Ufa wa UV – 2.0 mpaka 3.0 mils kutengera substrate
-Utoto wa Solventborne – makulidwe a filimu youma ya 1.0 mil
• Zinthu zophikira mu uvuni/kutsuka
Ufa wa UV - kusungunuka kwa mphindi imodzi, masekondi awiri kuchiritsa UV
-Solventborne - mphindi 30 pa madigiri 264 F
• Chithunzi sichikuphatikizapo substrate
Ntchito yogwiritsira ntchito ufa wa electrostatic ya makina ophikira ufa wophikira UV ndi makina ophikira ufa wa thermoset ndi yofanana. Komabe, kulekanitsa ntchito za kusungunuka/kuyenda ndi njira yophikira ndi khalidwe losiyanitsa pakati pa makina ophikira ufa wophikira UV ndi makina ophikira ufa wophikira. Kulekanitsa kumeneku kumathandiza purosesa kuwongolera ntchito zosungunuka/kuyenda ndi kuchiritsa molondola komanso moyenera, ndipo kumathandiza kugwiritsa ntchito mphamvu moyenera, kukonza kagwiritsidwe ntchito ka zinthu komanso chofunika kwambiri kuwonjezera mtundu wa kupanga (onani Chithunzi 2: Chithunzi cha Njira Yogwiritsira Ntchito Kuphimba Ufa Wophikira UV).
