1. Most of the plastic materials can be recycled, but due to the fact that plastics (water outlet materials) are more brittle than normal materials, they can only be used in combination with new materials (raw materials). The maximum proportion cannot be more than 25%. It should be suitable for customers. Standards are the principle. Since various types of plastic materials have different melting points and different injection pressures, they must not be confused in production.
2. Since the plastic products are to be matched with the colors, the plastic raw materials can be divided into: pumping granules, color powders, coloring materials, and the recent addition of liquids to color the plastic raw materials. The pumping raw materials are already mixed with pigments. In the raw material, each plastic material has been colored, so the product color is stable and uniform. The color powder material and the color material are used by mixing the color material or the toner, and the cost is low, and there is no need to store a large amount of colored material. Unstable, it is more difficult to control uniformity in production.
