2. High Voltage Electrostatic Spraying of Epoxy Powder System:
The powder spraying equipment includes stainless steel epoxy powder chamber ,fluidization box, powder pump, high voltage electrostatic generator, high voltage electrostatic spraying gun, combined control cabinet, powder two stage recovery device, compressed air system, grounding device and so on.
The rate of powdering is more than 95%.
The rate of powder recovery is 99%.
1). The wall of epoxy powder spraying chamber is made of stainless steel sheet. The powder chamber body does not form a loop on the whole structure. Therefore, it will not generate heat when it is near the mid-frequency induction heating ring. The powder will not stick to coke and reduce power consumption. The spray gun rack in the chamber can meet the gun in three-dimensional space flexible array, so as to ensure the best spraying effect.

2). The spray gun adopts high voltage electrostatic spraying gun and electric control system produced by Qingdao Dacang company. The spraying gun combines the characteristics of all kinds of powder spraying guns at home and abroad, and is specially used for pipeline spraying and coating.
High voltage electrostatic spraying gun
(1)The body is made of stainless steel rod, light and durable, not easy to stick powder.
(2) using PTFE material in the gun head, high temperature resistance, no deformation, non sticky powder.
(3)The core consists of a PTFE block and a steel wire rod, which can make the powder dispersed and easy to adjust, which is very important for the uniformity of powder and the rate of powdering.
(4) According to the above features, the spraying gun is very favorable for controlling the thickness of the powder. It can save the powder and reduce the cost.
3). Powder spray comprehensive control cabinet: the products are produced by Qingdao Dacang company.
High voltage electrostatic combined control cabinet
4). The method of powder recovery is double cyclone recovery and filter recovery.
