Powder coating paint dust spill is its normal state, good equipment is expensive, the design is reasonable, the safety margin is large, the dust is not serious; the cheap equipment is almost no design, plus maintenance can not keep up, spare parts Recycling is not timely, the use of powder particle size and material is not good, catching up with production progress, and then encountering high temperature and high humidity, etc., the recovery effect is more and more unsatisfactory, can not bear to witness.
After the powder comes out of the spray gun, there are the following types: the paint that is adsorbed onto the workpiece becomes effective, falls to the bottom of the spray booth, becomes the platform to recover the powder, is recycled to the filter, and is recycled by the shock or recycled by cyclone. It is directly discharged by the ultimate filter interception, discharge or primary recovery, and falls from the spray booth opening to the workplace.
6, increase the filtration area and improve the filtration accuracy. Under the premise of ensuring a specific negative pressure in the spray booth, the powder filtered through the final filter is made less. For this purpose, it is considered to use sufficient spray area ceiling or wall to design a space for powder filtration and sedimentation, while the filter material can contain more powder, and the slow flow rate facilitates the filtration of the powder and separation from the air.
