How to Improve Powder Coating Application Efficiency? (4）
Adding charged additives: Adding an appropriate amount of conductive additives to the formula can improve powder coating in areas such as grooves and dead corners where the electric field lines are weak due to the Faraday effect. In these areas, powder particles with more charge can reach the workpiece surface by their own force.

Appropriate selection of fillers: The fineness and dispersion of fillers are closely related to powder coating. Precipitated fillers have a higher powder coating rate than general ultrafine heavy barium, and barium sulfate is better than calcium carbonate.

Use high-resin formulations with good electrical properties. Epoxy powders are easier to apply than polyester. Tribo spray guns provide better leveling, allow thicker coatings, and reduce defects such as blooming and orange peel.

Control the powder particle size distribution—narrower is better. Properly controlling particle size (which is challenging) involves adjusting the rotational speeds of the primary and secondary mills in our ACM equipment during actual production. A particle size range of 35-45μm is considered suitable, with a narrower distribution being preferable.
Several things that must be done daily in a thermosetting powder coating spraying workshop (1)
A. Check if the recovery device is operating normally. B. Check if the high-voltage electrostatic generator is functioning normally according to the specified specifications.
Precautions to be taken during the application of thermosetting powder coatings (4)
F. Keep the area within 5 meters of the spraying area clean. Avoid sweeping; use a damp mop or vacuum cleaner instead. After powder coating application, wash your hands and face with hot water and soap.

E. When the powder coating spraying booth is in operation, operators must not enter the spraying booth. Personnel working in dusty environments must wear appropriate masks and protective gear.

C. Check if the exhaust system is working properly.
D. Check if the grounding of the fixtures and all electrical components is good.
