How the Effect of ABS can be Reach 60 Dyne After Treated by Atmospheric Plasma

Project Summary

• Technology: Plasma activate and modified
• Treatment Material: ABS
• Treatment Purpose: Improve printing adhesion
• Device Model: PM-G13A Atmospheric plasma treatment machine

PM-G13A Atmospheric plasma treatment machine is a portable device, it is just about 30 kg. It is single nozzle for treatment width 35-80 mm. When using plasma , you can connect the nitrogen or compressed air according to your need. In general, compressed air can reach good effect for almost material. But for some particular material, nitrogen can get better effect. PM-G13A plasma treater can combine with conveyor to reach high productivity.

ABS plastic is widely used in a variety of fields, which the largest application fields are automotive, electronics, toys, building materials and DIY production fields, they are processed into all kinds of products through bonding, printing, spraying, electroplating and other processes.

However, because the critical surface tension of ABS is relatively low, probably between 34 and 38 mN / cm, the activation treatment should be performed on its surface before these processes.

For example, when ABS is bonded, it is difficult for the adhesive to closely fit with the surface. After the plasma treatment, the adhesive wetting area can be greatly increased, and an active layer is formed on the surface, so that ABS plastic can be bonded very well. Therefore, for printing, spraying, bonding, which requires the material adhesion, the use of plasma cleaning technology can improve the surface activity and complete the product process production.

About the electroplating of ABS, Its process should go through oil removal, organic solvent pre-coarsening, chromic acid coarsening, activation, pre-plating, electroplating, this process will cause harm to both the environment and the human body. Choosing a plasma surface processor to replace it, which can save the use of organic solution and reduce the pollution damage.

Here are some advantages about the atmospheric plasma cleaning technology:

1. In the operation process of the plasma processor, there is no need to add other chemical solutions or catalytic substances, and the whole process will not produce any harmful pollutants, so it is a dry and environmentally friendly cleaning method
2. The cleaning effect of the plasma is not affected by the thickness, hardness and shape, and only acts on the surface of the object, and will not damage the material base
3. The low temperature plasma cold arc discharge technology at atmospheric pressure has short cleaning time, good effect and high efficiency
4. With a stable output efficiency, low temperature and won’t hurt human body
