SPRAY APPLICATION PROCESSES

摘要

The spray application of coatings to protect and decorate products has undergone considerable change since its inception some hundred years ago. The Industrial Revolution has given us an unlimited supply of new products to finish, along with an ever-increasing variety of coating materials to use on those parts to provide them with protection and decoration. Presently, we have four major processes of spray applications: (1) air atomization-conventional air spray and high-volume, low-pressure (HVLP) atomization, (2) airless atomization, (3) air-assisted airless atomization, and (4) electrostatic atomization, which can be combined with any of the three previously mentioned forms, or used with rotational atomizers. Regardless of the finishing system, all have their advantages as well as their limitations. What may be suitable for one situation may not be suitable in another.
