Methods of plastic testing for plastic pigments
1. Test equipment: single screw extruder L/D= 24 injection molding machine
2. Test raw materials: Pigment plastic decomposition (HDPE, PP, PS, etc.)
3. Test concentration: corresponding to titanium dioxide 1%
Pigment concentration respectively 0.1%, 0.05%, 0.025% 0.005%
4. Test: The quantitative pigment and plastic mixture can be extruded multiple times in a single-screw extruder according to the concentration of (3) into a uniform
Particles. In an injection molding machine, the samples are gradually manufactured and tested at intervals of 200°C, 220°C, 240°C, 260°C, 280°C, 300°C for a certain constant time.
