powder coating man should take care

For spraying equipment, we generally use the is powder coating, with the production of 

coating, spraying equipment demand also increases year by year and for the automotive 

industry, its shadow, the application of coating in the automotive industry is now very 

popular, now for everyone explain coating in the automotive industry is how to use the. 

With the increasing of the demand of coating in the automotive industry, paint variety 

occurred very much change, for the automotive industry, paint production the mixed type of 

epoxy, polyester and polyurethane type species, in the vehicle chassis, spare parts, 

wheels, joystick, mirror, wiper and speakers such as parts of the painting has very 

important application.

As we all know, the adhesion of powder coating is realized by the principle of electric field. But what is the principle of it? In fact, in each of the metal flow on the head of the gun are connected with a high voltage negative. Which leads to a large amount of negative charge on the powder when it is ejected. The sprayed workpiece is grounded to form a positive electrode, so that the powder is sprayed on the surface of the workpiece, and the surface of the workpiece is attached to the surface of the workpiece. 

After the heating and curing into a durable film. Because it is the principle of 

electromagnetic field adsorption. Therefore, it is almost difficult to destroy its internal 

structure, thus ensuring its adherence to the firm.

When using thermosetting powder coating, if improper use will cause a certain risk. Therefore, in the process of operation, not only can not be distracted, but also carefully. In the process of spraying if there is a powder coating material leakage phenomenon, must cut off the power supply 

first, then immediately clean up, and you want to find out the reasons, if in the work, coating is not carefully into the eyes must be immediately rinse with clear water, the situation is more serious, to the hospital for treatment, not to delay the time, so as to avoid greater harm.
