Brief special sublimation powder coating aluminum

Powder coatings, often referred to as dry paint is an environmentally friendly product that can offer more variety and more colors . We see more and more industries , more and more areas of application of powder coatings. With the rapid development of aluminum industry , used in powder coatings on aluminum has become a specialized branch , and gradually replace the electrophoretic paint and fluorocarbon . With the transfer of technology, but also to make special aluminum powder coating more colorful.

Requires a high strength Aluminum Alloys weatherability and decorative, therefore , must be performed on the aluminum surface treatment, surface treatment of aluminum are mainly organic coating, comprising powder coating , fluorocarbon coating and wood processing , the wood processing is also performed on the powder coating of the . Wood processing technology is divided into two kinds of water transfer and heat transfer , the technology into China since the late 1990s , with the rapid development in recent years . Its main characteristic is transferred image colorful, rich layers, its effect can be comparable with the printing and thermal transfer printing difference is that at high temperatures by sublimation thermal transfer ink , to multicolor patterns once into a graph, without trapping , condensate formed after the pattern of bright colors , and can penetrate into the powder paint coating inside 40 to 60 microns. Therefore, durable heat transfer products , patterns will not fall off , cracking and fading. Heat transfer products will not change the original gloss, abrasion resistance , weather resistance, acid and alkali resistance and other characteristics , heat transfer surface only play decorative effect. Entire heat transfer industry , has developed into a now largely complete supporting systems, including powder coating, spraying , heat transfer machine , transfer paper and transfer film manufacturing .

Thermal transfer technology but also to the emergence of powder coatings and presents new challenges that require the use of powder coatings, must be connected with thermal transfer paper, film matches , to get good transfer effect . Therefore, to explore the powder coating film sublimation thermal transfer technology and research powder coating formulation is necessary .

Thermal transfer technology in the aluminum on the application, no doubt to the special aluminum powder coating has brought boundless vitality, but also enriched the colorful nature of powder coatings . Many powder coating production plants are set up a special research and test team and specialized production workshop , there have been many professional production plant. These thermal transfer technology for developing special aluminum powder coating to promote the development has played a positive role. However , we also see the tear issues are also plagued some manufacturers . I have been to some of the aluminum powder coating plant, aluminum stickers and evacuation process is very smooth, but the tearing process becomes jammed and most of them were gathered in the tear-off and the final surface cleaning processes. How to make up tearing process is simple and smooth , powder coating formulations designed to explore aspects of the powder coating process to study coating , wood grain pattern ink on paper quality is also worthy of attention.
