[Dry Goods] UVLED Deep Curing Has Some Influencing Factors

Everyone knows that UVLED glue will change after ultraviolet radiation, but how does it change specifically? UVLED glue is caused by the light caused by the uvled raw, and the ionic group or ion is generated. These free groups or ions with the double -key in the premature or unsaturated monomer of the monomer are formed to form a single gene. The single gene starts chain reactions to generate polymer solids. In this way, a complete solidification process ends. But what are the factors that affect their deep solidification, this time I will take you a little bit about it. 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 light caused by the light caused by the provided UV coatings exceeds or less than the energy required. The negative effects of curing, such as aggregation, anti -aging reaction, 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 The ultraviolet light is different according to the solidified substrate, 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. 6. The impact of UVLED wavelengths of UVLED wavelengths is divided into 365nm, 385nm, 395nm, 405nm. At present, some UV glue and ink are longer and better in the wavelength.
