When UVLED curing technology has just been published, the use of UVLED curing can only be applied in some special industries, but after decades of development. Uvled curing has been popularized. This study cannot do without the UVLED, people on UVLED of Chengdu Chemical Group has been very understanding.

具有反应活性的化学配方内容构成了辐射固化的化学体系，一般包括齐聚物、单体、光引发剂、UV助剂等成分。

The chemical formula content with reaction activity constitutes a chemical system of radiation curing, generally include oligomers, monomers, photoinitiator, additives and other components of UV.

齐聚物在辐射固化配方中起着极其重要的作用，它决定了涂料、油墨、黏合剂或其他基料在辐射固化后的整体性能。齐聚物是专门指一类具有不饱和双键结构的高分子聚合物，可进一步发生反应，扩展成为交联固化体，故也称预聚物。大多数齐聚物都是不同类型丙稀酸树脂，分子量一般不大。

Oligomer plays an extremely important role in radiation curable formulations, which determines the coatings, inks, adhesives or other base material in the overall performance after radiation curing. Oligmer is a kind of special polymer with unsaturated double bond structure, can be further extended to become crosslinking reaction, so called prepolymer. Most of the oligomers are all different types of acrylic resin, molecular weight is generally small.

单体是有机合成材料最基本的单元，在辐射固化中单瘫主要是用作稀释剂以降低化学体系的黏度。UV固化单体一般为活性稀释剂，不仅可调节配方黏度，而且分子结构含有一个或多个双键，称作单官能团活性单体或多官能团活性单体。这种活性单体可与齐聚物或其他单体发生反应，参与辐射固化过程，而且由于不含挥发性物质，故不会对大气造成污染。

Monomer is organic synthetic material the most basic unit, in radiation curing paralysis is mainly used as diluent in order to reduce the viscosity of the chemical system. UV curing monomer is generally active diluent, not only can adjust the formula viscosity, and the molecular structure contains one or more double bonds, called the single functional group active monomer or multi functional monomer. The active monomer can react with oligomer or other monomer, and participate in the radiation curing process, and because of no volatile matter, it will not cause pollution to the atmosphere.

光引发剂在紫外光的作用下产生自由基和阳离子。这两种粒子在化学体系中都是高能活性基团，有利于引发单体、齐聚物和聚合物的不饱和双键的交联固化。

Under the action of UV light, free radicals and cations are generated. These two kinds of particles are high energy active groups in the chemical system, which are beneficial to the crosslinking and curing of the unsaturated double bonds of monomers, oligomers and polymers.

助剂在辐射固化中虽然并不直接参与固化过程，然而其作用不可忽视。最常用的助剂是稳定剂，主要用于防止配方用料在贮存时出现凝胶化现象，或防止配方体系在暗光条件下自动固化。此外，其他一些助剂，包括颜料、染料、消光剂、消泡剂、流平剂、附着力促进剂等在改善最终UV固化性能中也发挥着各自不同的作用。

In radiation curing process, the assistant is not directly involved in the curing process, however, its function can not be ignored. The most commonly used additives stabilizers, is mainly used to prevent the material composition in storage appear gelation phenomena, or to prevent the formulation system under the dark condition automatic curing. In addition, some other additives, pigments, dyes, matting agent, defoaming agent, leveling agent, adhesion promoter in improving the final curing performance in UV also play a different role.

Uvled的深度研究对于人们对其进行实际应用是有很多好处的。人们也开始慢慢意识到对uvled深入研究带来的好处。人们对其的研发投入将会越来越大。使其有着更好的性能与更广泛的应用。

The depth study of Uvled for people of its practical application has many benefits. People began to slowly realize the benefits brought to the in-depth study of uvled. The R & D investment will be more and more. The application has a better performance and more widely.
