A consultant to High-Performance Powder Coating examines expenditures, functionality, and environmental results. The textual content appears to be like at technical advances made in powder coating systems and gear, and it explains those techniques for these within the attempting to preserve a aggressive area. Powder coating fabrics and their functionality houses are checked out in addition to electrostatic theories, curing, and ovens. The booklet appears at layout and building elements of the pretreatment washing machine approach and explores tracking and protecting pretreatment platforms, besides the basics of warding off pretreatment failure. different themes contain gear hoppers and feeders, powder cubicles, functions, working stipulations, and issues of safety. functionality checking out, together with criteria and chemical resistance, are defined. additionally, troubleshooting methods while a product is off color, off gloss, or shows negative adhesion features is gifted

Example text

Pressurized air flows through a diffuser plate into a powder chamber, causing the powder to become suspended (fluidized) in the airstream. In this state, the air-powder mixture resembles a boiling liquid. The part to be coated is heated to a temperature above the powder’s melting point and then immersed in the air-powder mixture (see Figure 2-2). The powder particles that contact the hot surface begin to fuse and form a film on the surface. Uniform distribution of particles over the surface is enhanced by vibrating the part while it is in the powder chamber.

Larger particles are likely to be deposited on top of existing uncured coating. When viewing a cross-section of an uncured powder-coating layer, the bottom portion (closer to the metal) would likely have a smaller average particle size than the top portion. A powder coating may not flow well during the curing process. p65 34 4/10/02, 11:39 AM Powder Process and Electrostatic Theory Figure 4-1. Electric field between two charges. uncured coating layer. This results in lower gloss, bumpy finishes, and orange peel due to the insufficient flow properties of the powder coating (Guskov 1996).

Hybrid powders provide a somewhat softer surface than epoxy powders. Hybrid powders’ corrosion resistance properties are similar to epoxy powders, but their resistance to solvents and alkali is generally inferior to pure epoxies. They have superb charging capabilities, which means that the first-pass transfer efficiency is excellent with good penetration into corners and recesses. Some of the advantages of epoxy-polyester hybrids include: • • • • • • • • • good adhesion, high resistance to yellowing, no volatile compounds emitted during curing, excellent transfer efficiency, excellent wrap-around properties, good intercoat adhesion, less sensitive to substrates, good mechanical properties, and good resistance to salt spray.
