powder coating pretreatment

Coating application of soapy water washed down with a neutral detergent and rinse with water. When powder coating projects are fitted with no damage to the powder coating, and they keep them 

regularly, they should be relatively fixed. The correct application of the coating, although there is no metal metallurgical bonded will not crack, with the traditional film chip or stripping. Powder coating composition, which can be produced in the first experiment of melting film has been in 1940s. These are the thermoplastic powders. This is hardly similar to today's powder coatings. 1952, fluidized bed is the first time to be able to paint the number of industry. Then and now, the layer thickness is greater than 200 microns, which is 3 to 4 times as usual, produce and powder coating applied to thick layer. Further breakthrough. This is a shorter time to set up and a more stable quality, is to achieve. This is key to the application of large scale systems. In the early 70's is also found in the TGIC polyester system with high weather resistance curing agent. At the same time coming to the first acrylate - and the polyurethane system was able to perform at the beginning of it. The distribution principle for the powder coating technology is the regulation, technical description of air pollution (for short: the clean air act).

Innovation is the addition of powder coating, especially the water based coatings, high solid paint (the so-called high solid content of paint) and radiation force. Two main features of powder coatings, surface treatments are most like: decoration and / or function. This combines the advantages of powder coating appearance with the durability of fine zinc plating. 

However, the customer said that because galvanized finish will not have time to heal, powder coating is minor, but in practice easily, people feel the risk is a complete and low maintenance complete advantage over began. Hot dip galvanizing is a modern and advanced technology products, steel anti rust protection, provides a thick metal zinc envelope, completely cover the surface of the iron and steel, and the environment of the corrosive effect of sealing. The hot dip galvanized products, steel cleaning degreasing, pickling, chemical cleaning to obtain surface. Between 

the zinc plated zinc and steel zinc solution, in a few minutes of high temperature. Usually this kind of wear-resistant coating can last for many years, there is little or no maintenance. Zinc plated and has a limited life, however, its effectiveness as a barrier directly depends on the thickness of the coating and the environment (e.g., there will be a short life time exposure to salt water or contaminants).
