In recent years, with the continuous development of rotational molding technology, many friends are also very interested in rotational molding technology. How are the colors of colorful rotational molding products painted?
After being processed and formed, roll molded products need to be colored, processed, and then sold to the market. Polyethylene is difficult to paint on the ground surface, while others are easier to paint. Painting the surface of rotary molding molds has always been a difficult problem, how to solve it?
1. The use of gasification materials and the addition of a certain proportion of oxidizing materials during the mixing process of rotary molding molds will affect the surface characteristics and some physical properties of the parts.
2. Chemical oxidation, chemical reagents oxidize the surface of products.
3. Corona discharge is used to treat the surface of PE products by generating plasma arcs through high voltage in the discharge chamber.
4. Flame treatment, using flames to create an oxide layer on the surface of the product, making it easier for the paint to adhere to the surface of the product.
5. Polymer alloying or modification, mixed with other polymer materials or fillers for ground surface energy, can allow products to be directly painted.
6. Radiation treatment can be used to modify the surface characteristics of rolling molds.
There are many methods for coloring rotary molded products. We can use chemical oxidation, flame treatment, polymer alloying, or modification methods to apply paint. These materials are used to fill the paint, making it easier for it to adhere to the surface.
