The selection of spray room and recovery system is related to many factors, such as powder color, powder type, workpiece shape, installation site, spraying requirements, etc. The spray room itself has many types, from the recycling system, there are filter single-stage recycling spray room, small cyclone two-stage recycling spray room, large cyclone two-stage recycling spray room, etc.; from the material of spray room, it can be divided into stainless steel plate spray room, plastic spraying steel plate spray room, engineering plastic spray room, sandwich spray room, etc.; from the sprayed workpiece, it can be divided into ordinary Hardware spray room and aluminum profile spray room From the point of powder spraying, it can be divided into ordinary organic powder spraying system and enamel powder spraying system

Powder is the biggest consumption material of electrostatic powder spraying line, which accounts for more than 70% of the cost of consumable materials of electrostatic powder spraying line. The quality of spraying room and recycling system is related to the consumption of powder per unit area. Therefore, the selection of a suitable spray room system is closely related to the core competitiveness of customers.

In addition to the commonly used powder, many similar powder, metal powder, enamel powder, glossing powder, etc. have some special requirements for the spray room. Only a suitable system can guarantee the spray quality of customers and the maximum utilization rate of powder. Examples are as follows:

For micro powder spraying (now it is generally considered that the average particle size below 20um is defined as micro powder), the most economical way is to use single-stage recovery of filter element with high capture efficiency, which can save powder to the maximum extent. If large cyclone or small cyclone recovery is adopted, some special designs are needed, which can reduce the amount of waste powder in the secondary recovery system.

For general metal powder, it is easy to produce color difference when the powder is recycled. Therefore, the recycling path should be shortened as far as possible, and the recycled powder and new powder should be evenly proportioned.

For glossing powder, because of its high resin content and easy oxidation, it is not suitable to pass through high-speed recovery pipeline. At the same time, in order to ensure the quality of spraying, the recovery of glossing powder should be filtered by a powder sieve of more than 180 mesh.
