Powder Coating Application

SUPPRESSION EQUIPMENT The application of ” Explosion Suppression Equipment ” such as a fire extinguishing system that commonly uses halogen gases propelled by pyrotechnic devices can stop an explosion from occurring within the collection system. CONTROL OF DUST Design of the spray booth and recovery system can aid in worker safety.  The booth opening, velocity of airflow must be arranged to assure the capture and containment of over-sprayed powder.  The fan capacity of the recovery system must be sized toRead More …

Masking is a very important step in the powder coatings process. It is labor intensive and expensive. The type of masking material and its properties will be important to the effectiveness of the mask and its impact on production efficiency. There are many commercially available masking materials for and powder coated parts. Tapes, plugs, caps and steel fixtures can be used. These cost and benefit issues are considered to determine the best possible way to mask a part: the cost per mask the numberRead More …

Powder coating application systems provide pollution prevention over traditional spray application systems due to the higher transfer efficiency (above 90%), and very low volatilization of organic solvents. Install a booth recovery system for electrostatic spraying and flocking applications. Booth recovery systems collect overspray powder particles from the exhaust air so that they may be reused. Reduce or eliminate contamination of coatings by enclosing and covering work areas. Surround systems with a semi-open structure which allows operation of the process butRead More …

Electrostatically applied powder can entrain airborne dirt and deposit it on the parts. They are the hardest to track and eliminate because they can come from so many different sources. Keeping a clean environment around the system is one of the best ways to reduce air borne dirt.The list below names some of the common sources of airborne contamination during powder coating application Process Equipment – The conveyor, the oven, the washer or other operations within the coating line can generateRead More …
