Example of powder coating spray guns. The most common way of applying the powder coating to metal objects is to spray the powder using an electrostatic gun, or corona gun. The gun imparts a negative charge to the powder, which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the ...
The following is a list of industrial occupations. Industrial occupations are generally characterized by being manual-labour-intensive and requiring little to no education. Industrial occupations are generally characterized by being manual-labour-intensive and requiring little to no education.
Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. Paint, in the form of either powdered particles or atomized liquid, is initially projected towards a conductive workpiece using normal spraying methods, and is then accelerated toward the work piece by a powerful electrostatic charge.
The coating acts as a sacrificial layer when it comes in contact with another surface so that the base material underneath is protected and remains unharmed. [2] [3] Abradable Powder Coatings safely reduce operating clearances and friction to improve the efficiency of compressors, pumps, engines, blowers, etc.
A job description or JD is a written narrative that describes the general tasks, or other related duties, and responsibilities of a position. It may specify the functionary to whom the position reports, specifications such as the qualifications or skills needed by the person in the job, information about the equipment, tools and work aids used, working conditions, physical demands, and a ...
The coating penetrates better into pits and crevices. A uniform thick coating is produced, reducing the number of coats required. A very "wet" coating is applied, ensuring good adhesion and flow-out. Most coatings can be sprayed with very little thinner added, thereby reducing drying time and decreasing the release of solvent into the environment.
Cromax, a water-based product, and the industrial paints Nap-Gard, a powder coating for oil and gas pipeline companies, and Voltatex for electrical insulation, were introduced in the 1990s. [4] Other products made by Axalta include Abcite, Alesta, AquaEC, Audurra, Centari, Challenger, Harmonized Coating Technologies, Imron, and Nason.
The molten powder ‘flows’ into the profile and bonds with the steel. The molten powder will become a solid coating, when the ‘gel time’ is over, which usually occurs within few seconds after coating application. The resin part of coating will undergo cross-linking, which is known as “curing” under the hot condition.
