Analysis of the Causes of Poor Spraying of Spraying Robots

&Nbsp; At present, the degree of automation is also increasing, so the application range of spray painting robots is gradually expanding and penetrating into multiple fields. The conveying part is mostly carried out using stainless steel mesh chains, and the conveying chains of spray painting production lines can directly contact the manufacturers. When the paint spraying robot is not debugged correctly, there may be paint defects during spraying. The reasons summarized by the editor are generally as follows: sagging and excessive dilution. Cracking, excessive use of curing agent, improper combination. Excessive or insufficient addition of orange peel curing agent. Pinholes, excessive addition of curing agents, excessive construction clay, etc. How to deal with situations like this& Nbsp; Image 1: Streaming; Excessive dilution. One coating is too thick, the surface is uneven, unclean, the shape is complex, or there is oil and water. The nozzle is too large and too close to the object surface. Improper spraying speed& Nbsp& Nbsp; Solution:; Reduce the dilution ratio. Apply multiple times to avoid excessive thickness in one application. Handle the surface properly. The appropriate diameter is between 1.5 and 2.8mm. Depending on the spraying viscosity, grasp the spraying speed well& Nbsp; Image 2: Cracking; The amount of curing agent used is too large, and the combination is improper. The coating is too thick, the surface is dry and the inner layer is not dry. The bottom layer is unclean, improperly handled, and left standing for a long time after polishing. Matching of bottom and top coats& Nbsp; Solution:; The paint was not thoroughly stirred before use, and the color of the upper layer material was insufficient. Mix according to the required ratio and stir thoroughly. Each coating should not be too thick. Handle the substrate well, and the re spraying time should not be too long. The primer and topcoat should be matched. The paint should be thoroughly mixed before construction& Nbsp; Image 3: Orange Peel; Excessive or insufficient addition of curing agent. Improper ratio of diluent. Spraying pressure is too high or the nozzle is too close to the object surface. The construction temperature is too high or too low& Nbsp; Solution:; Add curing agent in proportion. Control the dilution ratio. The pressure should not be too high and the distance should not be too close. Pay attention to the construction temperature& Nbsp; Image 4: Pinhole; Too much curing agent added, resulting in excessive construction clay. The construction environment temperature is too high. Excessive spray pressure and insufficient interval time between layers. The nozzle pressure is too high, the diameter is too small, and it is too close to the object surface& Nbsp; Solution:; The time left for mixing the paint is too short. Adjust the construction viscosity and master the paint ratio. In summer, when the temperature is high, solid agents should be reduced and diluents should be added. Spray in two installments and reapply after surface drying. Choose an appropriate caliber, with a pressure not exceeding 4kg/cm, and a spraying distance not exceeding 25cm. Stir well and let stand for 10-20 filtration& Nbsp; Image 5: Bubbles
  The surface moisture content is high and the temperature is high. There is moisture in the air compressor or pipeline. Poor sealing of putty on the surface. The storage time is too short after adding curing agent& Nbsp; Solution:; The surface is dry and should not be exposed to sunlight. Use an oil-water separator for separation. Choose high-quality putty. It is advisable to leave it for 10-20 minutes and spray it twice. After the surface dries, reapply& Nbsp; Image 6: Local loss of light; Insufficient dilution, too fast drying, and too thick paint film. Use an incompatible diluent. The base surface is rough and uneven. The construction environment has too low temperature and high humidity& Nbsp; Solution:; According to the correct ratio, grasp the thickness of the paint film. Increase the dilution ratio in summer. Smooth the base surface and polish the primer. Ensure that the temperature and humidity of the construction site meet the requirements& Nbsp; Image 7: Granulation; Mixed with impurities. Change different types of paint before cleaning the spray gun. The nozzle pressure is too high, the diameter is too small, and the distance from the object surface is too far. The paint has been left for too long after adding thinner. Insufficient mixing and standing& Nbsp; Solution:; Keep the construction site clean. Different types of paint cannot be mixed for use. Choose an appropriate caliber, the spraying distance should not exceed 25mm, the storage time should not be too long, and the dilution should not be too much. Stir thoroughly and let stand& Nbsp; Spraying robot technology is a high-tech equipment technology, and spraying robots have many advantages: good paint film quality, smooth and delicate coating, good adhesion, long coating life, high coating utilization rate, and easy spraying to corners and gaps. You can also drag your hands to teach programming, greatly reducing on-site debugging time, and the utilization rate of spraying robots can reach 90-95.
