The piano at home was repainted.

Piano paint, as a kind of paint, is a kind of PE paint in polyester paint. Strictly speaking, it should be unsaturated polyester PE piano paint, which is a high-gloss unsaturated polyester paint. The reason for this requirement is that all kinds of common paints, such as polyurethane PU paint, nitro NC paint, light-cured UV paint, etc., all have high-gloss mirror paint, but the principle of high light-curing is different. Some of these paints are not easily separated from piano paints in appearance.

It is not enough to use "piano paint as pigment". Unsaturated polyester PE high-gloss paint, like many paints, can use a variety of spraying processes. Therefore, technical requirements are also necessary standards.

The most important thing in the process of piano baking paint is baking paint. The so-called baking paint is the process of sending the workpiece into the painting room after painting or painting, and curing the paint layer by electric heating or far infrared heating.

Piano baking paint process is a kind of baking paint process, and the process is very complicated. First, you need to paint putty on the board as the bottom layer of painting; Leveling the putty, and grinding until the putty is dry; Then spray the primer repeatedly for 3-5 times, and polish it with water sandpaper and emery cloth after each spray; Finally, spray 1-3 times bright topcoat, and then bake and cure the paint layer at high temperature.
