Coating materials investigated in the experiment were latex paint [3], alkyd paint [4], conversion varnish [5], finishing varnish [6], wood stain [2] and so on.
The polyurethane varnish is widely used in the decoration and protection of wood-based materials, metallic materials, and other building materials.
Furthermore, researchers in other countries seldom study organic pollution from wet coating materials made in China.

Fig .2 Workpiece and roller geometrical model in the shaped blank cogging According to the model of the DEFORM material warehouse, the rollers are all defined rigidities, selecting rigid material model, Q235 steel as the workpiece according to spot actual steel and elastic-plastic material model as the material model.
The material parameters and hot steel mechanical performance parameters of high temperature steel such as elastic modulus E, poisson ratio and stress-strain curve of Q235 steel in the different temperatures have been determined with Gleeble-1500 thermal simulation machine.
