Application of Colorimeter in Cable Plastic Industry

Color control is a very important job in the cable industry, and there are strict standards. The color display of the cable not only shows the quality problem of the product, but also an important symbol of the function of the cable. In most of the operation and construction, the function of the cable is directly identified by the color of the cable. Therefore, the detection of cable plastic color becomes very important. The Colorimeter occupies a pivotal position here.

There are also strict international standards and regulations on the color of cable plastic products. With the development of the industry, the requirements for the color of cable plastic are getting higher and higher. The color management that can be distinguished by naked eyes can no longer satisfy this industry. This is why the Colorimeter began to rise in the cable plastic industry.

A cable company in Hong Kong specializes in the production of telephone cables and indoor telephone wires. At the same time, these companies export telephone cables, and the color requirements for the exported cable plastics are even stricter. Not only must they meet international standards, but also pay attention to the local cable requirements of the exporting country. , so the requirements for the color difference meter are more stringent in terms of color difference detection.

In view of the small diameter of the cable and the difficulty of measurement, Sanen proposed two measurement schemes for customers to choose from. First, the choice of Colorimeter. We suggested NH310 for customers. This Colorimeter has stable performance and has two measurement calibers for area size, There are solutions for curved surface products, but the diameter area of ​​the cable plastic is still too small. The minimum measurement aperture of the NH310 Colorimeter is 4mm, but this aperture is not enough to be covered by the cable as a whole, so the solution we give to customers is:

1. Cut the cable plastic from the middle position with a knife and lay it flat. In this way, the area of ​​the cable plastic to be measured becomes larger. In addition, the NH310 has a camera positioning function, which can be well positioned and measured. But we are also worried that customers have a lot of finished products to measure, and this method is not suitable.

2. We use the winding method to measure the cable plastic wires that cannot be measured separately, because the electric union plastic wire is relatively thick compared with ordinary wires, so we use a circular mold with a diameter of more than 4cm (the one we used in the company's measurement) It is a PV water pipe), wrap the cable plastic wire tightly on the PV pipe, and pay attention to remember that there should be no gaps between the wires and the wires must be completely close together.

NH310 is a high-quality professional color analysis instrument with high-precision measurement and stable performance. It can realize yellowness and whiteness testing, and can take the average value of multi-point testing. It is suitable for enterprises.

The above are some application introductions of Colorimeters in cable plastic color detection, hoping to provide some references for relevant users in the industry.
