UV 固化系统
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
热固化
a) 通过挥发性物质的蒸发达到固化效果。 所需能量通过红外线照射或热风获得。
b) 固化层的厚度会损失,多少取决于挥发的量。挥发物质必须排放出去。

 

紫外光的化学固化 (= UV固化)
a) 通过聚合反应达到固化效果,也就是长分子链的交联反应. 交联反应所需能量来自紫外光的辐射。
b) 固体的厚度固化前后没有变化。
