Surface treatment process for rapid prototype: introduction of painting


The prototype processed by the rapid prototype needs to be post-processed. There are also many processes in the post-processing. The surface treatment process of the rapid prototype model of plastic and metal materials includes: grinding, polishing, laser engraving (laser engraving), electroplating, painting, silk screen, Oxidation, baking, drawing, etching, etc. Today, let's take a look at the surface treatment process of painting.

 

First of all, the first process of painting is the first primer, which is used to fill the sand marks and micropores of the bottom layer of the workpiece, increase the adhesion of the underlying coating, and also has a defect indication function.

 

Next is the intermediate primer. This coating is very important. Prepare a complete smooth working surface for the next process, complete the final process of all primer work, increase the adhesion of the intervening layer and have a certain isolation. Ensure the quality stability of the topcoat.

 

Then there is the topcoat. The topcoat is the color determining layer and the decorative protective layer. The painting quality of the topcoat part is very high. It needs to be bright, clean, evenly glossed, not color cast, plump, not hanging, not hanging, no gun. Good leveling, no bottoming, no leakage, no impetuousness, all these aspects are done, it is not easy to do it in one go, it requires a lot of experience and fault pre-arrangement ability.

 

The top coat is divided into a single layer paint and a multi-layer paint. The single layer paint is commonly referred to as plain paint, also known as ordinary paint, and can be finished in one layer; multi-layer paint is divided into pearl series paint and silver powder series paint, and pearl paint series is composed of Mica flakes and shells are made of high-tech materials. They are high-grade and highly decorative high-grade paints. Silver paints are made of special aluminum materials, which have high protection and outdoor stability. Strong observability

What is the last process? It is the lacquer finish. After the paint surface is dried, the enamel on the top is treated. The spray spray is not perfect. For example, the car's loading paint will have a slight fish scale phenomenon. This is the paint film. The natural phenomenon caused by the drying time difference in the leveling process, we collectively refer to the orange peel phenomenon, which requires the treatment of the paint surface. We first use the sandpaper for flattening and then use the coarse wax composed of pumice or clay. Grinding and cutting off the sandpaper marks, the next step is to grind with fine wax, to remove the traces of the crude wax, and then to treat with a reducing agent to achieve a perfect gloss, and then use a mirror treatment to completely remove the aura and the smear. The deepest layer of gloss, and finally the glaze, so that you can achieve the perfect finish.
