UV vacuum coating paint production line

Production process 1. Surface treatment: Usually, before the coating, the substrate (plating) for degreasing, dust and other pretreatment, in order to ensure that the plating of clean and dry, to avoid the primer layer pitting, poor adhesion and other shortcomings. For special materials, such as PE (polyethylene) materials, it should be modified to achieve the desired effect of coating. 2. Primer, surface coating: spraying construction, you can use automatic spraying, can also be used artificial spray and dip coating, depending on the specific size, shape, structure and user equipment and other specific circumstances and customer quality requirements. 3. Primer Drying: The purpose of drying is to improve production efficiency. Usually the drying temperature is 60-70 ° C for about 2 hours. Drying requirements are complete drying of the paint film. 4. Topcoat drying: usually surface coating than the bottom coating is thin, so the drying temperature is low, about 50-60 ℃, time about 1 to 2 hours, the user can be based on the actual situation of flexible grasp, and ultimately should ensure that the surface coating Layer thoroughly dry. If the plating does not require coloring, the process has come to an end. 5. Coating: coating, should ensure that the vacuum of the coating machine to meet the requirements, and then heating the tungsten wire, and strictly control the heating time. At the same time, should be mastered the amount of metal coating (such as aluminum), too little may cause the metal film can not cover the substrate, too much in addition to waste, but also affect the tungsten wire life and coating quality. 6. Water stains: If the plating needs to be stained with water, you can dry the finish of the plating into the dye tank, the color of the dye, and then rinse dry. Dyeing should pay attention to control the temperature of water, usually about 60 ~ 80 ℃, and should control the time of water pollution. The disadvantage of water stains is easy to fade, but the cost is low. A variety of water stains my company has supporting sales. 7. Oil stained color: If the plating products need to be stained with oil stains, the coating after the customer requirements, directly with SZ-matte color oil, SZ-transparent color oil dip or spray, dry can. The color of the oil stains do not fade, the cost is slightly higher than the water. process: Loading→ → Electrostatic Precipitation → Flame treatment→ →Spray Primer → Primer Drying → → Unloading → Vacuum metallizing Coating → Loading → Automatic Electrostatic Precipitation → Spray top Paint → UV Curing → Cooling → Unloading
