Powder coating is an excellent option for protecting and extending the life of metal products. For applying it to metal you need special equipment. And its obligatory part is a powder gun and its price depends on many factors. For saving money on a spray gun you need to get acquainted with their types and exact applying purposes.<\/span><\/p>\r\n

Powder coating principle<\/b><\/h2>\r\n

Powder paint is a fine powder that is applied to a metal product according to the principle of electrification. Particles of paint receive a charge and the product receives a charge opposite to them. The opposite charges are gravitated and the paint is deposited on the surface. The strength of adhesion depends on the strength of electrification.<\/span><\/p>\r\n

It is the sprayer that gives the charge to the particles. A good paint gun will charge the particles enough so that the maximum amount is deposited on the object being painted the first time.<\/span><\/p>\r\n\r\n\r\n\r\n

There are two types of paint guns: tribostatic and electrostatic. They differ in the principle of charging paint particles, and are intended for different purposes. We will talk about them in detail below.<\/span><\/p>\r\n

Tribostatic powder gun<\/b><\/h2>\r\n

The tribostatic gun charges powder particles by friction. They rub against each other and against the barrel of the sprayer at high speed, thus charging.<\/span><\/p>\r\n

This gun works like this: paint is poured into the tank, it is attached to the device, a hose for the transport air flow from the air intake is attached to its end part, the gun is grounded, turned on, the powder is mixed with air and the mixture flow is released through the nozzle.\u00a0<\/span><\/p>\r\n

In the process, the powder particles are charged and apply at the surface.<\/span><\/p>\r\n

A tribostatic powder paint gun is cheaper than an electrostatic one. It has a very simple design. The operation of this device is greatly influenced by materials moisture and the relative humidity in production. In low temperature environments they become less effective.<\/span><\/p>\r\n

Also, not all paints can be used for tribostatic painting. Only very high quality,epoxy ones, are suitable. The performance of the gun depends on the size of the tank. And the charge becomes less intense if there is little paint in the tank.<\/span><\/p>\r\n

Therefore, the tribostatic gun is best used for painting small products of complex shape. Due to the fact that it has small voltage there is no reverse ionization during painting and there is no Faraday cage effect.<\/span><\/p>\r\n\r\n\r\n\r\n

Electrostatic powder gun<\/b><\/h2>\r\n

The electrostatic gun charges the particles with an external source. It must be additionally purchased with the gun. In this case the powder charges by force what gives the possibility to apply it to any metal with any paint.<\/span><\/p>\r\n

An external source gives the paint a significant charge. Therefore, it is better to buy them for coloring large items. Because of significant charge various problems might happen during painting parts of complex shapes. For example, the paint will be thicker around the grooves, and not get inside. Or the inner corners will not be painted.<\/span><\/p>\r\n

The distance between the gun and the item to be painted is irrelevant.<\/span><\/p>\r\n\r\n\r\n\r\n

\"\u042d\u043b\u0435\u043a\u0442\u0440\u043e\u0441\u0442\u0430\u0442\u0438\u0447\u0435\u0441\u043a\u0438\u0439<\/figure>\r\n\r\n\r\n\r\n

It is necessary to choose a gun based on what object to paint. It is better to take an electrostatic spray gun for large products of a simple form. If products have complex shapes, for example, mesh, then tribostatic is better.<\/span><\/p>\r\n

You can buy a tribostatic or electrostatic powder gun from Smartline. The company’s specialists will tell you more about these devices and help you to choose the best option for your production.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
