UV 固化系統 The UV curing process uses UV energy and light from the visible light spectrum in wavelengths from 200 to 480 nm. UV energy "cures" inks and varnishes in a fraction of a second. A UV system consists essentially of the following components: UV lamps, reflectors, lamp housings, a cooling system and an electronic operating and control system. A range of additional options can then be added as required. We manufacture to the highest quality standards with precise production of individual components, meticulous calibration of the UV units and the seamless integration of the UV system into the production process.
固化原理 熱固化
a) 通過揮發性物質的蒸發達到固化效果。 所需能量通過紅外線照射或熱風獲得。
b) 固化層的厚度會損失,多少取決于揮發的量。揮發物質必須排放出去。
紫外光的化學固化 (= UV固化)
a) 通過聚合反應達到固化效果,也就是長分子鏈的交聯反應. 交聯反應所需能量來自紫外光的輻射。
b) 固體的厚度固化前后沒有變化。
