In recent years, as people attach importance to environmental protection, more and more manufacturers begin to switch from traditional solvent based coating to environmentally friendly, VOC free UV coating. The quality of UV coating film depends on three aspects: UV coating, UV coating equipment and process, and UV coating management. It is the so-called “three points of paint, seven points of process”. First, we should choose a suitable UV coating according to our own products and existing equipment. It is necessary to consider the operability of the coating, the performance after film formation (brightness, hardness, saturation, acid and alkali resistance, etc.), cost performance, environmental protection requirements, etc. Secondly, mature technology and good equipment are also key. The quality of the paint film depends not only on the characteristics of the paint itself, but also on the process and conditions of forming the paint film. The inferior coating will certainly not produce perfect painting effect, but the high-quality UV coating will also not produce the expected effect if the construction and matching are improper. For example, pretreatment of painting can increase the adhesion between paint film and substrate; Unstable equipment operation will cause uneven coating film thickness; The coating effect will be affected if the drying equipment cannot reach the strength or is too strong. Third, coating management is the guarantee of the quality of the paint film and the necessary condition to ensure the implementation of the process and the normal functioning of the coating equipment. At present, the painting workshop usually uses the “5S” on-site management method. The “5S” management method is attached for sorting out: the workshop should be separated from the unnecessary items, and the unnecessary items should be removed. Rectification: The workshop shall locate and quantify the required objects, and tidy up the disordered objects in an orderly manner. Cleaning: Clean the workshop like a person washing his face. Cleanliness: Keep the workshop clean, free of dust and garbage. Literacy: improve the consciousness, sense of responsibility, quality and accomplishment of all employees, and cultivate the idea of being the master of the family.
