Coloring plastics color powder (or pigment powders) requires caution and attention to a few key points to ensure you get an even coloration and avoid problems. Here are some important things to note when using toner:
well mixed:
Make sure the toner is thoroughly mixed before adding it to the plastic pellets or resin. Uneven mixing can lead to uneven or patchy color issues.
Choose the appropriate recipe:
Make sure you choose the right color powder formula to get the color you want. Color formulas may include different types of pigments and different proportions.
Control color intensity:
Color density refers to the ratio of toner to plastic. A tinting concentration that is too high may result in a color that is too intense, while a concentration that is too low may result in a color that is not noticeable. Control the coloring intensity according to the desired depth of color.
temperature control:
Temperature is critical to the dispersion and mixing of toner. Make sure that the temperature of the processing equipment is suitable for mixing the toner and remains stable throughout the processing process.
Mixing equipment:
Use specialized mixing equipment or mixing machinery (toner machines) to ensure that the toner is fully dispersed in the plastic. Hand mixing is usually not enough to ensure even coloration.
Pigment stability:
Consider the stability and durability of the pigment. Certain pigments may change color or fade under certain conditions, which requires special attention.
QC:
Establish quality control procedures to ensure consistent color and quality from batch to batch. It is a good practice to conduct regular color checks and sample testing.
cleaning equipment:
Clean processing equipment and containers to ensure color cross-contamination does not occur. Avoid mixing different colors of toner together.
safety:
When handling and handling pigments, take appropriate safety measures, such as wearing a respirator, gloves, and goggles to prevent inhalation or contact with pigment dust.
