Processing painting

Quality levels are the result of a ratio of parts defective to parts produced. The current trend is to use parts per million (ppm) but this is not always practical for some processes. Painting processes for instance cannot achieve blemish-free surfaces in the order of one blemish per million parts painted ... 

Flow coating In this process, paint is directed on to the workpiece from a series of strategically placed jets in an enclosed area and the excess paint... 

Curtain coating With this process, paint falls in a continuous curtain from a closely machined gap in a header tank on to the flat article passing below on a horizontal conveyor the excess paint is collected in the main tank and then passed up to the header tank. It is an ideal method of applying thicker coatings (60/im and above) to sheet metalwork.

People may also be exposed to selenium from industrial sources. Humans are normally not exposed to large amounts of selenium in the air, unless selenium dust or volatile selenium compounds are formed in their workplace. Occupations in which humans may be exposed to selenium in the air are the metal industries, selenium-recovery processes, paint manufacturing, and special trades. Selenium dioxide and elemental selenium can be released into the air during the burning of coal and oil. In addition, irrigation runoff may cause high levels of selenium in fresh water and can lead to high concentrations in some of the fish and birds that live there.
