Plasma surface treatment equipment with increased adhesion:

Low temperature plasma is to point to by air pressure low charge and discharge (glow, corona discharge, high frequency, etc.) caused by the ionized gas, under electrostatic field effect, free charge from electrostatic field in the gas kinetic energy, into a high energy electron devices, so this kind of material is how to make and so on ion surface treatment equipment can improve surface adhesion stick relay will explain to you.

Plasma surface treatment equipment

Such a high energy electron and gas in the molecular structure, molecular collision, the electron kinetic energy than molecular structure or molecules can provoke, will provoke molecular structure or provoke molecular oxygen free radical, cation, and have different kinetic energy radiation, they according to the ion bombardment or introducing polymer surface, cause off key or import functional group heterogeneity, which make the surface produces specificity, thus achieve the goal of modified materials.

Surface active adhesion efficacy of plasma surface treatment equipment:


1. Under the effect of plasma, a part of specific molecules, oxygen free radicals and unsaturated bonds appeared on the surface of refractory plastics. This specific functional group contacted with the specific particles in the plasma, resulting in new specific functional groups. However, materials with specific functional groups will suffer from the effect of oxygen or the movement of molecular structure chains, which will cause the surface active functional groups to disappear.

2. When the plasma surface treatment equipment carries out surface modification of the material, the effect of the surface active particles on the surface molecular structure causes the unchain of the surface molecular structure, which leads to new specific functional groups such as oxygen free radicals and hydrocarbon groups, and then produces surface chemical crosslinking and polymerization.

3. Reactive plasma refers to that the specific particles in the plasma can produce chemical changes with the surface of the refractory raw materials, and then introduce a lot of functional groups, so that the surface of the material changes from non-polar to optical rotation, and the interfacial tension and viscosity are improved.

4. Under the high velocity impact of plasma, the chemical crosslinking of molecular structure unchaining occurs on the surface of the refractory material, which promotes the relative molecular weight of the surface molecular structure, improves the situation of the weak boundary layer, and has a positive effect on the improvement of the adhesion characteristics of the surface layer.

The key reflecting plasma specific gases in plasma surface treatment equipment include 02, H2, NH3, CDA and other gases. Related plasma surface treatment equipment can improve the surface adhesion of the material is introduced to this, I hope to help you oh.
