Sannshi color difference meter for color control in the plastics industry

The change of colors in the natural world has brought endless beauty and charm to human beings. We lament his magic and dexterity, but this color that changes at any time is not so good for industrial production. The change of color is very likely to cause the formation of chromatic aberration in industrial products, which will cause the product to fail, which will increase the cost and reduce the efficiency. Based on this, the appearance of the San'en Colorimeter will be so popular.

There are more and more applications of plastics in industry, such as packaging, promotion, accessories, etc. Plastics are widely used. People have higher and higher requirements for the color of plastics. The introduction of the Sannshi color difference meter is to fill this gap. In terms of color control, Play a role. Sann's color difference meter is a tool for color quantification, a ruler for color matching and color communication.
Analysis of Main Factors of Plastic Color Difference Using Sann Time Color Difference Meter

1. Affected by plastic masterbatch: It is not difficult to see the color data of the Sannshi color difference meter that the plastic masterbatch itself has color difference, especially when some masterbatch itself has a certain base color. Sometimes the color masterbatch uses the same model but different batches, and the color measurement results of the Sann's color difference meter are also color difference. The experimental data of the Sanenshi color difference meter show that the size of the color difference is directly proportional to the degree of similarity of the base color of the masterbatch, that is, the larger the difference of the base color of the masterbatch measured by the Sanenshi color difference meter, the greater the color difference produced by the product.

2. Affected by plastic color masterbatch: Color masterbatch is the most important factor that produces color difference. Analysis of color measurement data of Sannshi color difference meter shows that the color quality of plastic directly depends on the quality of the base color of the color masterbatch. The experimental data of the Sannshi color difference meter show that the thermal stability, dispersibility, and covering ability of the color master batch directly affect the color difference of the product. The analysis of the cause of the color difference of the Sann's color difference meter uses a higher quality color masterbatch, which not only helps to reduce the color difference, but also improves the overall appearance of the injection molded product.

3. The effect of uneven mixing of color masterbatch and raw materials: The color masterbatch is mainly made by mixing colorants, dispersants, and plastic raw materials. A slight change in the colorant measurement will have a huge impact on the color of plastic products. When testing the samples of different doses of colorants in the Sannshi color difference meter, it can be seen that the color data changes greatly. One color masterbatch is often made of several colorants, and the ratio between them is different. The obtained color masterbatch The color of the products produced changes accordingly.

4. The impact of injection temperature and back pressure: Different product colors are shown. According to the three-color time difference meter data of camel pp color masterbatch, the injection product color is obviously reddish when the barrel temperature is 160 degrees Celsius, and the color will be increased when the temperature rises to 190 degrees Celsius White, when the temperature rises above 220 degrees Celsius, the color is obviously black. The color data of these Sannshi color difference meters can be seen that the change in the barrel temperature of the injection directly affects the color difference.

We use the measurement and experimental data analysis of the Sanen Shi color difference meter to analyze the causes of the injection color difference. We pay attention to these issues during the production process to effectively avoid the problem of plastic injection color difference and improve the intensity of color management. Accurate measurement plays a decisive role in the control of injection molding, so we must use the Sannshi color difference meter in real time and correctly.
