Powder coating booth in general adopting engineering plastic, it including both PVC and PP. PVC usually applied in common powder coating booth,
PP used in high-end quality powder coating booth. The engineering plastic has good insulating property, which is uneasy to accumulate the powder on the booth and easy to clean.
1.Use the PP or PVC is easy to get the powder coating booth cleaned (fast color change).
2.If using conductive material as the powder coating booth wall, there will accumulate the powder easily on the powder coating room wall.
When the accumulated powder is thick enough, it will be easy to off to contaminate the finished painted workpieces.
From the structure of the powder coating line, it can be seen, if using pvc material, the structure commonly is of compact structure combined with single lever filter recovery system (in general, it is widely installed on both side of the powder coating room), the powder coating powder center can be fixed or unset. If fixed powder coating powder center, it will only can offer 1 kind of color.If unset color, it can offer at most 3 kind of color, namely it is of fast color change powder coating booth.
If using PP, the common sturcture will be of teo lever recovery system including big cyclone and second lever powder recovery system, the powder recovery nearly up to 98.9%, the function of the PP powder coating line is better than PVC powder coating line, the PP powder coating line is autmaticly powder recycle, the recycled powder is much more clean.
