Special silicone gun powder delivery tube

Powder coating process, although there are many advantages, and far beyond the environmental aspects of the painting process, but because of the short time to enter the domestic level of popularity in the country is not very high, many users of the solution of the spraying process is not very deep. So warm to remind the user in the choice of electrostatic powder coating equipment necessary to refer to more professional advice. Let's look at some of the more typical performance of electrostatic spray gun misunderstanding: misunderstanding: the higher the voltage gun, the powder sooner the better. Analysis: 1. According to the basic physical principles of electrostatic spraying can I know, when the charging voltage beyond a certain value but will intensify "Faraday effect" and "anti-ionization effect" occurs, the more impact the extraction rate. 2. electrostatic voltage is too high gunpoint likely to cause ignition of the phenomenon, easy to leave pinholes in the workpiece appearance, adverse apparent quality. 3. High voltage ignition phenomenon will increase dusting indoor dust ignites. Therefore, the actual use of the process should be adjusted to the appropriate phase voltage ability to obtain relatively good coating results in accordance with the characteristics of the powder, the characteristics of the workpiece and the like. Myth: You can use a simple shape of the workpiece so satisfactory performance of the gun. Analysis: 1. Some users believe that the simple shape of the workpiece, it is not necessary a good performance of the gun. In fact more than just a good performance on the shape of the gun's customer service ability, more importantly, a uniform powder state level will be better apparent coating and the extraction rate. And the flour yield a powder of course will save significantly reduce production costs. 2. The electrostatic properties of good will speed up production and improve efficiency. 3. powder evenly on the rejection rate will increase, reduce scrap rates, production management easier. The poor performance of the gun due to the components used in relatively poor performance, though lower interest, however, the failure rate will be much higher, even though manufacturers are bound to delay the production of timely maintenance. Accordingly, the workpiece shape is definitely not the reason to choose poor performance of gun. Moreover, in the superior interest Hao letter control system, AK series gun has been achieved in high-end products - low price price increase. I believe a majority of users to meet the production and interest, and many other requirements. Myth: the greater the amount of powder gun, the higher the extraction rate, work faster. Analysis: 1. temporary work process, meet many users make gun powder on a powder bigger is definitely better. In fact, the rate of gun powder on the case, only the electric field intensity and the amount of powder to achieve the best performance with the point from the static state and flour together determine the best talent on the extraction rate. 2. The gun flour too much will certainly affect a uniform powder state, which is the number of large amount of powder in powder spray gun is very uneven root causes. The poor state of the powder is likely to result in non-uniform coating thickness problems. 3. By foreign large number of experimental data and practical experience I can draw out the amount of gun powder in 450g / min on foot work demands a greater amount of powder will only lead to a partial powder simply can not live without adhesion, direct fall into the recovery system, causing serious waste. The excellent performance of the gun is the electric field strength in accordance with the best ratio of the amount of powder developed not only to eliminate the unnecessary waste, but resorted to a uniform powder state of perfection, and more to improve the extraction rate. Therefore, the amount of powder is not the better, but not as small as possible. In short, the most appropriate is the most valuable Myth: transparency mistaken powder spray gun is low, intuitive sense flour large concentration of gun. Analysis: good performance gun charge, since it is possible to discharge the charge on the powder particles a sufficient amount of electrostatic charge, so that the powder particles acquire sufficient electrostatic repulsion between each other, so that the powder particles of the powder after leaving the gun among non-adhesion, showing a very good atomization, from the side, will feel the powder evenly transparency, resulting in "the pink little" illusion. The poor performance of the charging powder spray gun, not between powder particles sufficient electrostatic repulsion between the powder particles into the film adhesion, good atomization effect, viewed from the front of the gun, powder spray low transparency, often resulting in "the pink more" illusion. Practice has proved that, when used for the same amount of powder (the same set of facilities for the powder, the same atmospheric conditions, the same box powder) to the charging performance for different gun powder, charging poor powder spray gun from the front low transparency, intuitive feeling high powder concentration; and excellent charging performance spray gun powder from the front is high transparency, low concentrations of intuitive sense. Therefore, the same amount of powder two gun powder atomizer spray charging performance the better the better, the higher the transparency of the front view, a front view of the low powder rather than transparency, intuitive concentration of a large amount of powder gun out more . Solutions for several common misunderstanding later, to talk about what kind of gun is easy to use a powder flow, powder spray evenly, continuously adjustable amount of flour, powder atomized mist spray of fine particles because, It should form a beautiful mushroom translucent. Two pairs of powder charge effect of the fine, has a very significant electrostatic adsorption capacity, sprayed onto the workpiece powder is sucked up by electrostatic attraction force rather than piled up powder sprayed onto the workpiece by a certain limit will not shock or breeze fall off a lot. Dead portion 3 of the workpiece should be showing excellent performance on powder, this performance is the most important performance of electrostatic spray machines, because even seemingly simple piece also likely to have several more difficult Spray dead position. 4 high extraction rate, high extraction rate equivalent to the high powder utilization, thereby reducing production costs, over time, electrostatic spray machine for the user in terms of, meaning of course important. 5 good metal powder coating capabilities; powder emerged in recent years because of various art effects on the market, many of which are mixed with metal powder called metal powder, electrostatic spray machine to buy now, you should be able to adapt to the requirements of metal Spray Powder (there are many electrostatic powder spray dryer on undesirable or severe heat gun when spraying metal powder, easy to burn the gun) 6 good secondary painting ability, to have sprayed a workpiece if unexpected rework or for other reasons required in the original coating (already cured) look even twice or three times and then spray again when the gun is still able to claim on a uniform powder. 7 the ability to work long hours; there are a lot of electrostatic spray without continual work (beyond 8 hours) because the gun severe fever, but in fact, it often requires a long period of continuous spraying to evict eight high-voltage electrostatic control proper duration, easy ignition, ignition can cause the outer coating of the workpiece appear breakdown point, leading to the appearance of the occurrence of pinholes workpiece scrap; and strong at the moment of ignition due to static electricity is not short-circuit the arc on the powder; another frequent ignition easy to make people lack a sense of security, affecting the normal operation of spray painting hand. In addition to the above process equipment performance is reliable, there are a few things to note: 1 equipment electrical work environment quality and the stability of industrial processing equipment than at home, and sometimes poor environment and often work continuously for a long time non-stop, so the stability of the equipment is very important. 2 technical service and after-sales service many customers need to have a rich experience in the production of technical expert guidance of talented enough to successfully master the electrostatic powder (electrostatic spray technology) and general did not provide this service, the client can probably teach use. Hao letter will be the users as friends, to explain all the problems you are experiencing, to help you solve all the difficulties you are experiencing.
