[Deep Solidification] There Are These Reasons for Deep Curing

The UV coatings are caused by the light caused by UVLED, which produces a per ingreline or ions. Gene starts 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 molecule must absorb light quantum with sufficient energy and become a stimulating molecule. It is decomposed into free radicals or ions. The purpose of reaction to achieve solidification. Among them, the UVLED energy of the optical caused by the light caused by the provided UV coatings exceeds or less than the energy required. 1. I do nt know the energy required for the light source required by light, such as blind supply, this approach not only wastes energy, but also causes the negative effects of excessive solidification, such as explosion gathering, reflux reactions, etc. 2. When UVLED is insufficient, the energy of UVLED must be moderate, that is, it cannot be excessive or insufficient, so as not to cause it to 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 shadow, temperature, curing speed, and substrate surface of the thick coatings of UV coating must be appropriately prepared under different conditions such as different conditions such as. Third, the impact of the curing distance UV ultraviolet light depending on the difference in the curing substrate, the general distance is 10-15mm right. The curing distance must be appropriately adjusted with the substrate, coating, UV light power, and the type of UV light. For example, when using UVLED curing lights, the distance you need is much smaller than the traditional UV mercury lamp. 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.
