Why Flame Treatment in Paint Spraying?
Flame treatment principle Flame treatment is a widely used process for surface modification of substrates such as plastics, glass and metal foils to improve their adhesion to liquids such as inks, paints, binders and coatings. Plastics used for flamming are thermoplastics and thermosets. When heated, thermoplastics will gradually soften and melt with the increase of temperature, and will become hard after cooling.At the same time, this process is reversible. We generally use surface tension or surface energy to measure the ability of the substrate to adsorb liquids, and if the substrate surface energy is at a high level, the liquid will become more wetted on its surface and have good ductility. Making the liquid more wetted on the substrate is the basis for the substrate to adsorb the liquid. If…
