It is said that electrostatic spray is better, where is it better? Below Hanna Technology to analyze for everyone! !First, electrostatic spray molding has excellent film properties: as long as the powder coating is directly sprayed onto the surface of the pre-treated MDF sheet, after baking, a coati
The Hanna powder coating line manual quick color change solution will reduce production stagnation time and increase productivity.
Color change time: 15 minutes
Disadvantages: Not suitable for multiple color change
Hanna patent: Filter recovery unit quick disassemble is convenient for color change
Powder recovery rate: 98%
There are many factors affecting electrostatic powder coating, such as equipment factors and operating factors. However, the main factors are powder conductivity, powder particle size, spray voltage, spray distance (between gun and workpiece), and supply pressure.1. Powder Conductivity: The volume o
For most users, is not very familiar with the coating technology and the powder coating application, so there will be some blind spots during the purchase process. How to choose the right powder coating line, let us start from the common appearing misunderstandings to analyze how to choose the right one.
1.Usually powder spray is normal and now the amount of powder spray is small. It is possible to block the powder pump core with impurities such as recycled powder or solidified substances in the powder pump. Unscrew the powder pump and clean it up.B. Check the four pressure gauges, which may have a large fluid pressure or open the cleaning and atomizing gas.

Electrostatic Powder Spraying - Causes and Solutions for Uneven Coating Thickness. Cause:
1. The rough and bad pre-treatment of workpiece.
2. The curing time is too long or the temperature of curing oven is too high.
3. There are volatile gases in the furnace.
4. The proportion of recycled powder is too large.
5. Two different types of powder mix.
6. Poor quality of powder.
1. Select the appropriate pretreatment process.
2. Adjust the appropriate curing conditions.
3. Clean the oven.
4. After the recycled powder is filtered, it should be mixed with fresh powder, preferably less than 30%.
5. Thoroughly clean the dusting system before powder change.
6. Replace the good quality powder.
