Temperature sensitive color changing powder and plastic injection procedures
1. First wet the surface of the plastic material to be injected with an appropriate amount of diffusion oil;
2. According to the proportion of 0.5%-1%, add the color changing powder to the plastic material, stir well;
3. Add 0.5%-0.8% diffusion powder or diffusion oil to the mixture and mix well. Mixing machine, kneading machine, high speed dispersing machine and other equipment can not be used in the mixing process.
4. Dry the mixture before injection molding;
5. Stir evenly, control the injection temperature within 200 degrees, and try to shorten the injection time;
6. The plastic material does not contain any white pigment or calcium carbonate, so as not to affect the effect.
