What should be paid attention to after using plasma treatment?
Author:Original Click :1429 Date: 2021-03-17

In actual production, after the surface of the material is treated, it is necessary to ensure that the surface is clean, not worn, and the storage temperature should not be high, and the process of printing, spraying or gluing should be implemented as soon as possible to avoid the deterioration of the treatment effect and the deterioration of the adaptability of the material . Matters needing attention in actual operation: 1. Plasma treatment is nano-level treatment. The effects of cleaning, activation and etching only occur on the surface of the material, about a few to tens of nanometers, so the treated surface cannot be wiped, and physical friction will cause some surface molecules. Falling off or compounding, the surface roughness decreases, resulting in a decrease in surface energy; 2. The product after plasma treatment cannot be baked at high temperature or placed in a place where the temperature is too high. Too high temperature will cause the free rotation or free migration of molecular chains on the surface to be processed, and accelerate the active groups to turn to adjacent molecules or groups. , Which leads to accelerated decline of treatment effect; 3. The treated surface cannot be cleaned with active liquids such as alcohol or acetone. Active liquids such as alcohol will directly react with the active groups on the surface to be treated to reduce the active groups and accelerate the decline of the treatment effect; 4. Based on the above basic principles, in actual production, you should also be careful not to directly touch the treated surface with your hands, so as to avoid friction, hand sweat, oil stains, etc., which may cause damage to the treated surface. In summary, plasma treatment is nano-level cleaning and activation, which has a good effect on the removal of microscopic dirt and the activation of the surface of the material without changing the original performance of the material. The treated surface does not need other treatments, and can be directly subjected to printing, bonding and other processes. If other treatments are carried out after the plasma treatment, it will cause the opposite effect, leading to the decline of the treatment effect of the treated surface. If the product quality requirements are high or the surface of the substrate is seriously polluted, it is usually necessary to add alcohol wiping or ultrasonic cleaning before the plasma process to achieve better results.
