RAL 1003 Protective Antimicrobial Powder Coating For Outdoor Metal Structures

Bad symtoms

Possible Cause

Solution

1.With low power, powder

coating is not easy to coated;

1. High voltage power supply shortage;

1.Check the circuit

2.Grouding is bad;

2.Remove clutter grouding line

3.Compressed air volume is too big,

the powder to blow fell &blows away;

3.Spray appropriate isolation,

reduct air convection;

4.Powder particle size is too thin;

4.Add new powder coating, reduce the

recovery powder consumption.

5.The air temperature is too high;

5.Powder particles with air water

branch of low power, control

temperature of spray area;

2. Charge repulsion powder

repboud from the working

surface;

1.The voltage is too high;

1. Lower voltage and air volume;

2.Spray gun from the work location is

too close;

2. Extend the spray gun and artifacts;

3. Grouding is bad;

3.Remove clutter grouding line;

4.Powder particle size is too thin, not

esay to attach to the workpiece surface;

4.Add new powder coating, reduce

the recovery powder consumption;

3. Corner not easy spraying

penetration is bad;

1. The powder amount is too small;

1. Lower voltage and air volume,

increasing the amount of powder;

2. Grouding is bad;

2. Adjust the spray gun position;

3. The voltage is too high;

3. Choose small backboard, proper nozzle;

4. Spray gun position is not good;

4.If the corner is more and deeper, then

consider friction gun equipment;

5. Powder spraying range is too wide;

4.Powder spraying uneven

1. Air pressure is insufficient;

1. Cleaning pipeline, spray gun and flowmeter;

2.Line fault block;

2.Check the air supply, Exclude water vapor

in powder agglomeration;

3.Block in the spray gun;

3.If powder agglomeration, to screen or

change new powder coating;
