Nyob rau hauv 20 xyoo dhau los, UV curing inks tau siv dav hauv daim teb ntawm lithographic ink. Raws li qee qhov kev tshawb fawb kev lag luam, [1,2] radiation curable inks tau kwv yees tias yuav txaus siab rau 10 feem pua kev loj hlob.
Qhov kev loj hlob no kuj yog vim muaj kev txhim kho tas mus li hauv thev naus laus zis luam ntawv. Kev tsim kho tshiab hauv cov tshuab luam ntawv (cov tshuab sheetfed thiab web hauv kev tsim khoom ceev ceev thiab cov khoom siv inking / dampening) thiab cov khoom siv ziab (nitrogen blanketing thiab teeb txias) tau ua rau muaj kev nce ntxiv ntawm cov ntawv thov hauv kev lag luam kos duab, suav nrog cov thawv rau cov tshuaj pleev ib ce, khoom noj, luam yeeb, cawv, daim ntawv ua lag luam, xa ntawv ncaj qha, daim pib lottery thiab daim npav rho nyiaj.
Kev tsim cov tshuaj luam ntawv UV kho tau nyob ntawm ntau yam. Hauv tsab ntawv no, peb tau sim hais txog lub luag haujlwm ntawm tus cwj pwm ntawm monomer hauv daim ntawv qhia ua kua mem. Peb tau piav qhia tag nrho cov monomers hauv kev sib txhuam ntawm cov interfacial kom kwv yees lawv tus cwj pwm nrog dej hauv cov txheej txheem lithographic.
Ntxiv mus, cov kua mem tau tsim nrog cov monomers no thiab cov khoom siv kawg tau muab piv rau.
Tag nrho cov monomers siv hauv kev tshawb fawb yog Cray Valley cov khoom. Cov GPTA monomers tau raug tsim los hloov lawv qhov kev sib raug zoo nrog dej.
