Learning this depends on your heart or not. As long as you are careful, you can basically master painting, electromechanical and sheet metal in a month or two. It's relatively easy to learn, but it's harmful to the body, especially the respiratory tract. You should be careful. If you really decide to learn, it depends on your personal comprehension. Generally speaking, it takes two years to study, because you have just started. It takes a year to spray. It will also cause great damage to memory and respiratory tract. Usually you can become a master in two years. I have been a painting engineer for more than 65,438+00 years. Apprentices mainly see teachers. As long as you are willing to study and find a good painter to teach you, you will make rapid progress. If your master hides some tricks and only teaches you the overall situation, it may be a bit difficult. You should pay more attention to other small aspects. I have a painting process dedicated to you, I hope it will be helpful for your future study! If you encounter any problems that can't be solved in the future, I can help you, at least paint this piece! ① Brushing: When brushing with a paint brush, the brushing direction should be up and down first and then left and right, and the paint brush should not be dipped too much to prevent dripping. When painting heavy anticorrosive paint, the distance between paint brushes should not be too large to avoid the film being too thin. In case of rough surface, bulging corners and edges, special attention should be paid to it, and it is best to pre-coat it first. ② Roller coating: When roller coating is used, the paint dipped on the roller should be evenly distributed. When painting, the rolling speed should be kept constant and not too fast. Don't push the drum too hard. For sunken parts such as welds and incisions, it is especially necessary to handle them carefully, and it is best to precoat them first. ③ High-pressure airless spraying: This is the fastest painting method, and a very thick paint film can be obtained. Therefore, in order to achieve the specified film thickness, it is best to adopt the construction method of airless spraying. In actual painting, vertical and horizontal spraying methods should be adopted, such as up and down before left and right or up and down before left and right. The use of lacquerless spraying requires high skills. The spray gun should keep a horizontal distance from the surface of the coated object, and the spray gun should be prevented from swinging in a long distance or in an arc shape during operation. ④ Control of paint film thickness: In order to make heavy-duty anti-corrosion paint exert its best performance, adequate paint film thickness is extremely important. Therefore, the thickness of paint film must be strictly controlled. The thickness of each coating obtained by painting with a paint brush or roller is relatively thin, and the number of times of painting should be at least twice that of high-pressure airless spraying to reach the specified thickness. For corners, welds, cuts and other parts, brush them once before spraying, and then spray them on a large area to ensure the paint film thickness of the protruding parts. During construction, it should be painted on time and according to the dosage, and the thickness of paint film is often measured by wet film thickness gauge. Where the film thickness does not meet the requirements, it must be repainted. ⑤ Different types of coatings have different intervals, so the construction should be carried out according to the requirements of each coating. In particular, it is necessary to point out that it is best to finish the next coating at one time when the paint film is only dry, so that the upper and lower layers are slightly dissolved, and the problem of interlayer adhesion will not occur. After completely curing, if you brush it again, you should use sandpaper to polish it. ⑥ Usage: The usage in this manual is theoretical value, which refers to the amount of paint per unit area obtained by theoretical calculation under ideal conditions and uniform film thickness. The actual consumption of paint in the painting process depends on the thickness of paint film, the loss in the painting process, the painting method and the roughness of the painted surface, which has great correlation. When estimating the actual dosage of coatings, the theoretical dosage should generally be 50? 80% paint consumption. It will take at least half a year to get started. My uncle has studied technology for a year, and it is impossible to master it without three or five years. However, the harm of this business to life can not be ignored. Pay more attention, and the money will come quickly. As long as you have a stable career to learn this, it depends on whether you have the heart. As long as you are careful, you can basically master painting, electromechanical and sheet metal in a month or two, but it is harmful to your health. Especially the respiratory tract, be more careful. You should think carefully before you decide to study. If you really decide to learn, it depends on your personal comprehension. Generally speaking, it takes two years to study. Because when I first started learning, I could only grind putty. It takes a year to spray. It will also cause great damage to memory and respiratory tract. Usually you can become a master in two years. I have been a painting engineer for more than 65,438+00 years.
