UV Coatings Curing Principle to Affect UVLED Deep Light Curing

The principle of solidification of UV coatings: UV coatings are caused by the light caused by UVLED, producing sculpting groups or ions. Body gene, these monomer genes start chain reactions to generate polymer solids, a complete solidification process ends. Let's talk about several factors that affect their deep solidification. I. The deep curing of UVLED energy influence of ultraviolet radiation. The main condition is that the molecular absorption of light quantum with sufficient energy becomes stimulating molecules, breaks into free radicals or ions, and allows saturated organic objects to aggregate, delegate, cross -linking and other chemical reactions , To achieve the purpose of solidification. Among them, the UVLED energy of the light caused by the light caused by the provided UV coatings exceeds or less than the impact of the energy required: 1. I do not know that the UVLED cold light source energy required by the light caused by the light cause, such as blind supply, is not only a waste of energy, but also the energy, but also It will cause excessive solidification negative effects, such as explosion gathering, reflux reactions, etc. 2. When UVLED is insufficient, it cannot be completely solidified. Second, the thickness of UV coating thickness affects the effects of UV coating on the effect of ultraviolet curing. The coating is too thick, and the drying time is relatively long under the irradiation of the same power light source. On the one hand, it affects the drying of UV coatings. In addition On the one hand, the surface temperature of the substrate will be too high, resulting in deformation of the substrate; too thin coating will cause the product's surface gloss. In addition, the hue, temperature, curing speed, and substrate surface of the UV coating coatings need to be appropriately prepared under different conditions such as different conditions such as. Third, the effect of the curing distance. UV lamp Depending on the difference in curing substrates, the general distance is about 10-15mm. The curing distance must be appropriately adjusted with the radical power of the substrate, coating, and the UVLED light. Fourth, the impact of UV optical curing speed Depending on the substrate, coating, coating, curing distance, etc., appropriately adjust the curing speed of the device, the fixed speed is too fast, the UV paint on the substrate surface is sticky or the surface is not dry; The surface of the material will be aging. Fifth, the impact of the working environment. When the viscosity of UV coatings changes greatly due to the temperature, the room temperature should be adjusted. Generally, 15-25 C is more appropriate, and it is not necessary to be direct when solidified.
