General knowledge of coating: General essentials of spray gun repair and spraying technology

Core tips: [information]: 1 Hold the gun The gun is held by the palm, thumb, little finger and ring finger, and the middle finger and index finger are used to pull the trigger When some painters work for a long time, they change the way of holding the gun from time to time Sometimes they only use their thumbs, palms with little fingers, sometimes with ring fingers to hold the gun, middle fingers and index fingers to pull the trigger This can alleviate fatigue and improve labor efficiency 2 Orientation of spray gun to substrate surface The spray gun should be vertical to the substrate surface, or try to be vertical If the spray gun is slightly skewed, the result will inevitably cause the spray band to flow in one side and the other side Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: [news]: 1 Hold the gun The gun is held by the palm, thumb, little finger and ring finger, and the middle finger and index finger are used to pull the trigger When some painters work for a long time, they change the way of holding the gun from time to time Sometimes they only use their thumbs, palms with little fingers, sometimes with ring fingers to hold the gun, middle fingers and index fingers to pull the trigger This can alleviate fatigue and improve labor efficiency 2 Orientation of spray gun to substrate surface The spray gun should be vertical to the substrate surface, or try to be vertical If the spray gun is a little askew, the result will inevitably cause the spray band to flow to one side, while the other side will appear thin and lack of paint, which is likely to cause stripe coating 3 Distance from spray gun to substrate surface For the siphon spray gun, the best working distance is 15 ~ 20cm If the distance is too close, the flow may occur, and the color may even be inconsistent with the expected when spraying metallic flash paint or pearlescent paint If the distance is too far More than 20cm, it may lead to dry spraying, over spraying and poor leveling of the coating If the metallic flash paint is applied, the possibility of color change may also exist The pressure spray gun can be far away from the base material Generally, the best distance is about 20-30cm These are the basic principles that must be followed in spraying construction 4 The movement speed of the spray gun When spraying, the movement speed of the spray gun has a great influence on the coating effect If the spray gun moves too fast, the surface appears thin, poor leveling and rough; if the spray gun moves too slowly, the coating formed is too thick, which is likely to produce sagging The ideal moving speed of the spray gun is that once the spraying is finished, the new spraying layer appears to be so full and wet, neither thin, barren, nor excessively stacked In short, the movement speed of the spray gun shall be determined according to the specific situation of the construction site Generally speaking, for comparison only, the moving speed of the pressurized spray gun is faster than that of other types of spray guns 5 Trigger control The gun is controlled by the trigger The deeper the trigger is pulled, the greater the liquid flow rate In the process of traditional walking gun, the trigger is always locked, not half locked In order to avoid the accumulation of paint sprayed at the end of each walking gun, experienced painters should slightly loosen the trigger to reduce the paint supply Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
