Dual curing yog ib qho kev siv tshuab tshiab, uas ua ke nrog qhov zoo ntawm cov thermal curing thiab UV curing systems.Nws tuaj yeem muab kev khawb zoo heev thiab tshuaj tiv thaiv ntawm UV txheej, thaum tso duab ntxoov ntxoo los ntawm cov tshuaj tiv thaiv thermal.Qhov no feature ua dual curing ib tug txaus nyiam xaiv rau automotive sab hauv daim ntaub ntawv.Qhov yooj ntawm nws cov txheej txheem kuj tso cai rau tus neeg thov kev hloov kho thiab hloov kho cov kab ntau lawm uas twb muaj lawm yam tsis muaj lub tsev los ntawm kos.
Raws li lub ntsiab lus saum npoo ntawm lo lus "ob chav kho" qhia, lub tshuab no yog kev sib xyaw ntawm UV kho thiab kho cua sov.resins.UV acrylate monomer thiab oligomer, photoinitiator,acrylic cobthiab cov kuab tshuaj yog cov hauv paus muaj pes tsawg leeg.Lwm cov hloov kho resins thiab additives kuj tuaj yeem suav nrog hauv cov mis.Kev sib xyaw ua ke ntawm cov ntaub ntawv nyoos no tsim cov txheej txheem uas muaj qhov zoo adhesion rau ntau lub substrates, thaum muab qhov tsis zoo ntawm qhov tawv tawv, khawb tsis kam thiab hnav tsis kam.
Kev tshuaj ntsuam matrix ntawm ob txheej txheej txheej feem ntau muab faib ua plaub pawg: adhesion, khawb tsis kam, tshuaj tiv thaiv thiab huab cua tsis kam.Lub tshav kub-kho txheej tuaj yeem muaj qhov "kho nws tus kheej" tus yam ntxwv, thiab qhov tawg thiab khawb yuav ploj mus vim qhov hloov pauv ntawm cov resin.Txawm hais tias qhov no yog qhov muaj txiaj ntsig zoo los ntawm qhov pom ntawm qhov pom, nws kuj ua rau cov txheej txheem yooj yim rau ntau yam tshuaj.UV txheej feem ntau muaj qhov sib txawv ntawm qhov sib txuas ntawm qhov sib txuas, uas qhia tau zoo heev khawb tsis kam rigidity, tab sis cov txheej yog tsis yooj yim thiab yooj yim los tsim adhesion thiab huab cua teeb meem.
Tsuas muaj ob txoj kev ua tiav rau ob txheej txheej txheej: qhov cub rau thermal curing thiab ultraviolet teeb rau acrylate curing.Qhov no ua rau lub coater hloov pauv cov xim uas twb muaj lawm tsis tsim cov xim tshiab.
Ib qho teeb meem loj tshaj plaws ntawm kev siv tshuab dual curing yog qhov kev txwv ntawm kev sib xyaw xim.Feem ntau UV kho tshuab yog pob tshab lossis xim xim, vim xim yuav cuam tshuam rau UV kho.Pigments, pearl hmoov thiab hlau flakes tuaj yeem tiv thaiv kev kho mob los ntawm kev tawg ntawm ultraviolet hluav taws xob thiab tiv thaiv kom txaus ultraviolet rays los ntawm kev nkag mus rau hauv txheej (Daim duab 3).Qhov tshwm sim yog qhov tsim ntawm uncured acrylate nyob ze ntawm lub substrate interface.Qhov siab dua cov txheej txheem ntawm cov xim coatings, qhov ua kom zoo dua qub.
