In recent years, with the continuous development of rotomolding technology, many small partners are also very interested in rotomolding technology, to ask a small series of colorful rotomolding product color is painted on?

Rotoplastic products after processing molding, it should be colored, after processing, and then sold to the market, polyethylene because of the surface can be difficult to paint, other easier to paint. Paint on the surface of rotomolding mold has always been a difficult problem, how to solve it?

1, the use of gasification materials, rotoplastic mold mixed with a certain proportion of oxidized materials, will affect the surface characteristics of the parts and some physical properties.

2, chemical oxidation, chemical reagent oxidation product surface.

3, corona discharge, by the high voltage of the empty chamber to generate plasma arc treatment PE product surface.

4, flame treatment, with the flame on the surface of the parts to produce a layer of oxide, so that the paint is easier to stick to the surface of the product.

5, polymer alloying or modification, mixed with other polymer materials or surface energy filler polyethylene, can make the product can be painted directly.

6, radiation treatment, radiation treatment can be used to modify the surface characteristics of the rotomolding mold.

There are many ways to color rotoplastic products. We can paint by chemical oxidation, flame treatment, polymer alloying or modification, and fill with these materials to make the paint easier to adhere to the surface.
