light agent as is types light material 质, is light polymerization system in key/critical formed separation, therefore also by is light agent or UV curable agent, is types can in outer light or can light inner absorption can amount long, rear generate 自由基, cationic and other, from 而引发 mono polymerization, crosslinked and solid 化 化 combined material. light agent main/primary used for radiation curing industrial in UV solid technology, for UV system in solid speed rate has very large effect/influence, in UV solid system in has important 位. light agent absorption light can generate active property in can separation is large type, its in application most is 自由基 light agent, according to absorption type type it also can separation is outer light agent and can light agent.

in light polymerization system in, light agent ratio/proportion small, is can or important formed separation, it absorption long, 摩尔消 light and light reaction property for light property can has obvious effect/influence. remove outer, light agent for system in solid speed degree, 泛黄倾 toward and production cost has very large effect/influence. light agent separation absorption light can rear, main/primary through related chemical function 激发三 heavy generate active property material types, system polymerization, formed crosslinked structure.

light agent absorption and light main/primary 发射谱 belt/tape 交叠 越 more, light agent has 效辐射 strong/high degree high, improve/increase ink solid speed rate 效果就越 good. due to UV LED 波峰狭 narrow, can amount can in in relatively narrow outer light in, 导致UV solid can in in outer light in relatively narrow scope/range inner. currently UV LED solid light 源 波 long main/primary 包括365nm, 375nm, 385nm, 395nm and 405nm, types long light 源 发射 belt/tape wide is 10nm, 但市面 upper large more light agent in 300-370nm absorption property can relatively strong/high, in large 于370nm scope/range inner absorption property can relatively 差, 就导致UV LED solid system in light 源 发射 light and light agent absorption light is 不匹配, most effect/influence light agent efficiency. in addition, due to UV LED灯 especially is short 波UV LED功 rate relatively low, light strong/high and light efficiency relatively low, reduce light agent for its degree, effect/influence light agent efficiency.
