Paint knowledge | electrostatic spraying principle advantages and disadvantages of electrostatic spraying

Core tip: spraying is just a big statement, and there are many specific spraying methods Most of my friends may only have some knowledge of manual spraying before, but with the continuous progress of science, the disadvantages of this method have been gradually exposed, and now many construction personnel have begun to change this operation mode At present, for large-scale projects Most of them are electrostatic spraying, so what is electrostatic spraying? What is the principle of electrostatic spraying sometimes? What are the advantages and disadvantages of electrostatic spraying? Let's take these problems and continue to look down 1、 Principle of electrostatic spraying Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather coating Home news: spraying is just a big statement, and there are many specific spraying methods In the past, most of our friends may only have a certain understanding of manual spraying, but with the continuous progress of science, the disadvantages of this method have been gradually exposed, and now many construction personnel have begun to change this operation mode At present, for large-scale projects Electrostatic spraying is often used, so what is electrostatic spraying? What is the principle of electrostatic spraying sometimes? What are the advantages and disadvantages of electrostatic spraying? Let's take these problems and continue to look down 1、 The principle of electrostatic spraying is that the object to be coated is a positive electrode and the coating atomization device is a negative electrode The former is grounded while the latter is electrified, so two electrodes are formed Based on the principle of same-sex repulsion and different-sex absorption, the coating is ejected from the atomizing device, and finally an average and firm film is formed, which is the principle of electrostatic spraying 2、 Advantages of electrostatic spraying Compared with the original manual spraying, the biggest advantage of electrostatic spraying is high construction efficiency The original manual spraying is generally not suitable for large-area operation, while electrostatic spraying has no scruples for large-area operation The construction personnel can completely install multiple electrostatic spray guns and spray at the same time, which can effectively shorten the spraying time and improve the spraying efficiency The second advantage is that if only saving spraying time, electrostatic spraying will not be widely respected There is also a very significant advantage, that is, the film adhesion of electrostatic spraying is higher than that of manual spraying, and it can improve the utilization rate of the paint, ensure that the paint film is even and full, and play a good decorative role in the interior 3、 Disadvantages and shortcomings of electrostatic spraying of course, electrostatic spraying also has certain disadvantages Although electrostatic spraying is very suitable for large-area construction, electrostatic spraying is often difficult to fall down by some workpieces with complex shapes, which will produce uneven paint film, and also need to be repaired by people, resulting in more troublesome consequences The second disadvantage is that in addition to the above imperfections, electrostatic spraying requires a lot of investment and purchase of a large number of equipment Construction personnel should also be very careful when operating, and must strictly follow the operation requirements, otherwise electric shock and fire accidents will be caused 4、 Xiaobian summarized the principle of electrostatic spray painting I think you all know it Just now Xiaobian also introduced the advantages and disadvantages of electrostatic spray painting I believe that through the above introduction, you can find the key points and advantages Therefore, we must be very careful when choosing this operation mode 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,
