Standard Coating Application Apparatus Sample Clauses

Standard Coating Application Apparatus. The Formula 5 coating will be applied to the test panels using an airless spray gun, equipped with a 0.015 in. fluid tip. The application parameters for the airless spray gun, such as distance to the panels, application speed, number of passes, fluid delivery pressure, etc., will be determined during the start-up phase, prior to the verification test. The coating will be delivered to the airless spray gun at 2000 -3000 psi. The fluid delivery pump has a 30:1 pump ratio. The apparatus will be operated in one of the wet spray booths at CTC's ETF facility. Appendix A shows the selected apparatus setup, and Appendix B, shows the testing location relative to the Organic Finishing Line. Testing will be performed in one of the liquid spray booths in CTC’s Demonstration Factory. Standard test panels will be suspended from racks containing a single row of eight panels per rack, as shown in Appendix A, Apparatus Setup. The test panels will be fixtured on the rack to minimize movement during spraying. Fixturing consists of a flat bar that connects all eight hooks. The bar will minimize side-to-side rotation of the panels. A second bar is oriented near the bottom of the panels to prevent the bottom of the panels from moving away from the spray gun. The test panels will be transported to the spray booth by an overhead conveyor. A mechanical stop mechanism will align the racks of test panels in the proper position relative to the spraying mechanism. Once the racks are in position, the programmable logic controller (PLC) of the spraying mechanism will activate the motors that drive the linear motion translators. The translators will move both horizontally and vertically, enabling the application equipment to treat an area approximately 1.4 m by 1.4 m (4.5 ft. x 4.5 ft.). The panels will be automatically sprayed using vertical overlap of the spray pattern. The PLC will also trigger the pneumatic spray gun. During dwell time between passes, paint flow will be interrupted to minimize paint usage. Once the coating application is complete, the PLC will release the mechanical stop that maintains the position of the rack, enabling the overhead conveyor to move the next rack into position. Before the test, a set of dummy panels will be coated to ensure that the equipment parameters are set correctly. Evermore Paints and Coatings may wish to assist in this step. The fluid delivery pressure will be monitored periodically throughout the test. The paint usage will be determined thro...
