Chengfeng Zhizao will explain to you the relationship between plasma cleaner, contact angle tester and dyne pen:
The dyne pen is a test based on the surface performance of the dyne value. It is a basic detection method to quickly obtain the surface performance effect, rather than the "magic pen" or "felt tip pen" type. The principle of the dyne pen is very simple: separate the test part of the pen from the liquid storage part of the pen, in other words, the contaminants on the substrate will not be absorbed from the test liquid storage). By pressing the tube head and opening the valve, the tube head is filled with fresh liquid; flushed, and the tester is allowed to pass the sample to determine the dyne level. The result is based on the length of time it takes for the solution to form beads on the surface of the sample. Dyne test pens have all values from 30 to 70mN/m, and only one pen is provided. Use a dyne pen to measure the surface energy of the material (sometimes called the water droplet contact angle and surface tension). A quick test will determine whether the surface is processed to 38 mN/m or higher. The pen tip exerts a certain pressure on the measured surface. If the ink line shrinks or solidifies within 1-2 seconds, the surface will not reach the level of 38 dynes. If the ink mark is intact and there is no shrinkage, the surface of the sample is treated to make it reach 38 dyne or more.
The contact angle measuring instrument and the dyne pen, as a surface performance testing program, can test the products processed by the plasma cleaner in time. The atmospheric plasma cleaning machine is a solid platform for realizing various manufacturing application solutions. Adhesive dispensing, bonding and fixing, welding, printed circuit board wiring, etc. are just some of the applications. The operating software based on atmospheric pressure plasma makes programming simple and does not require complicated operating methods. This series of plasma cleaners allows one employee to operate multiple at the same time, which improves production efficiency.

In order to form a good bond with low surface energy materials (such as PP, PE, HDPE and other low or non-polar materials), we recommend plasma treatment of the plastic, using compressed air to generate high voltage, high frequency discharge or close to the treatment area Plasma discharge. This high-energy plasma can have a variety of industrial activities. In a highly active discharge environment, it can freely attach to free radicals and other particles. In addition, the polar groups formed on the surface of the material have a strong chemical attraction to inks, paints, coatings, adhesives, etc., so that the surface energy and adhesion are enhanced.
The plasma cleaner has the following functions:
1. Surface performance activation treatment;
2. Surface etching increases roughness;
3. Pre-adhesive treatment of various plastic materials can be carried out.
4. Clean the surface;
5. Improve adhesion.
