1.Friction type of spray gun
Friction gun structure is mainly composed of gun body and gun core, according to different applications, can be divided into three types.
(1) Portable gun.Body and gun core made from ptfe, so the whole quality of the gun does not exceed 750 g, 540 mm gun, powder amount to 20 ~ 250 g/min, is a relatively lightweight design, suitable for all kinds of dynamic spraying construction.
(2) Stationary.This is installed on the fixed frame or automatic elevator, to automated assembly line spray gun, hand gun, saves material handle, hook, such as solenoid valve switch components, so the structure is more simple, the main structure is a cylindrical shape of the friction of gun. In order to guarantee a certain amount of powder, often designed to multi-channel friction of gun, because of the friction in a spray gun with multiple channels, increased the friction powder area, make more friction with gun powder and get more charge, and can increase the quantity of powder, can guarantee the streamline the beat.
(3) Special.This is designed for the application of a particular object of the spray gun. Each specific application object has its own special requirements, such as steel tube wall when spraying powder coating, it requires that the quantity of powder spray gun, high charge/mass ratio, to spray, long enough steel pipe and can form various spray pattern. According to these requirements designed for this special spraying powder coating of steel pipe wall friction electrostatic spraying.
2.The design characteristics of friction
(1) Control the amount of powder injection. Into the air flow through the adjustment and the increase of gun tube diameter method can control the friction electrostatic powder spraying Si camping gun. But into the air volume is not too big, because too much into the air volume can increase the gun body and friction between the powder, increase the wear and tear of gun affect the service life of spray gun. Restricted by workpiece shape and pipe diameter, nor the gun body channels do very bulky, therefore can be designed as monomer in the form of double (multiple) channel.
(2) The form of the nozzle. To increase the friction area, between the powder particles, powder and the gun body more fully, the friction between the powder have enough power, usually the spray gun nozzle designed into a variety of forms, such as cylindrical, nozzle, when to leave due to powder coating spray gun mouth shape for divergent, so is suitable for spraying outside surface of the workpiece. Round hole shape of nozzle, coating powder in a straight line when you leave the spray gun mouth shape injection, so suitable for spraying the workpiece grooves etc. Elliptical hole shape of nozzle, the shape of the powder coating on a spray gun mouth for the sector, suitable for the inner surface of the spraying containers. So in the different parts of the spraying the workpiece, can according to need to change different nozzles, with a ? friction electrostatic spray gun can be completed a variety of graphics.
