Plasma surface modification equipment to treat different materials before pretreatment to improve adhesion


In different materials before the plasma surface modification equipment processing to improve adhesion, its cleaning principle is through the surface adhesion or adsorption of functional groups, to adapt to the specific application of the surface characteristics of the polymer surface cleaning activation, improve the ability of bonding.

Plasma jet cleaning

Plasma surface modification equipment for plasma activation circuit board, epoxy resin, PTFE printed circuit board etching and decontamination, gold contact deoxidization, O-ring plasma cleaning, PWIS cleaning, etc. There are strict requirements for the use of many O-rings and sealing elements, and the assemblies are free of any paint wetting damaging substances (such as silicone). This method can be used for coating, coating process and coating application, and also for some printed circuit boards which perform important wire welding tasks.

Plasma surface modification equipment

Elastic materials contain a large number of coating wetting damage substances, the traditional wetting process can not remove these substances. Softeners and release agents can be transferred from the body of the elastomer to the surface, causing quality problems. Plasma surface modification equipment Plasma cleaning processes are used to ensure compliance with standards in these components.

Plasma cleaning eliminates the barrier between paint and coating. It can remove silicone contaminants and increase the bonding force of various plastics. Improve the wettability of all polymer materials surface, plasma treatment printing adhesion processing of three-dimensional shape surface activation, for different materials such as metal, ceramic, glass printing textile plasma treatment can improve the performance of many industries, including semiconductors, medical, IC integrated circuits and so on.

Plasma surface modification equipment improves ink adhesion on difficult surfaces such as polypropylene (PP), polyethylene (PE), polycarbonate (PC) and polyamide (PA).

These surfaces can be wetting in seconds through machining and in-line plasma treatment, giving uniform, solvent-free inks with good printing adhesion. Plasma processing is an inherent cold processing technology, which is also suitable for thermal sensitive materials. Plasma treatment is especially suitable for different materials complex three-dimensional shape of metal, glass, ceramic surface activation, such as ionization treatment can achieve ink adhesion performance is good, improve the surface adhesion.

Plasma surface modification equipment principle:

1. The surface is treated by attachment or adsorption of functional groups to suit specific applications.

2, improve the polymer surface microstructure, improve adhesion.

3, plasma polymerization deposition of polymer layer, surface corrosion.

4. Plasma activates the grafted functional polymers or end groups on the surface.

5. Surface prepared for subsequent processing, such as thin film deposition or molecular adsorption.

6, improve the surface cover and spread of the coating, improve the adhesion and wettability between the two surfaces.

7. Wetting makes the surface hydrophilic.

8. Change the surface characteristics without affecting the material.
