Activation of plasma cleaner

Posted on


During the production process, many materials are difficult to bond, spray, print, weld, etc. due to the low surface energy. Chemical primers, liquid adhesives, flame treatment, and plasma treatment are all activation methods that can increase surface energy. Among them, chemical primers and liquid adhesives are often highly corrosive and environmentally hazardous, flame treatment is unstable, and the risk factor is high. The plasma cleaning machine has no damage, no pollution, no waste water, meets the requirements of environmental protection, and the process is stable and safe. It is a safe and stable surface activation treatment technology.

1. Activation Principle of Plasma Cleaning Machine

Activation in air or oxygen plasma, the non-polar hydrogen bonds of the plastic polymer are replaced by oxygen bonds, providing free valence electrons to the surface to combine with liquid molecules, thereby improving the "non-adhesive" plastic has a good adhesion And sprayability. In the vacuum plasma, other gases can be used in addition to air and oxygen. These gases can adsorb nitrogen, amines, or carbonyl groups as reactive groups at the position of oxygen. The activity of the surface after treatment by the plasma cleaner is still effective after several weeks and months. However, follow-up processing should be carried out as soon as possible, because as it ages, it will absorb new dirt and lose its activity.
 
Second, the use of plasma cleaning machine

1 Plasma surface activation / cleaning; 2 Adhesion after plasma treatment; 3 Plasma etching / activation; 4 Plasma degumming; 5 Plasma coating (hydrophilic, hydrophobic); 6 Enhanced bonding; 7 Plasma coating; 8 Plasma ashing And surface modification and other occasions. Through its treatment, it can improve the wetting ability of the material surface, enable a variety of materials to be coated, plated and other operations, enhance adhesion, bonding force, and at the same time remove organic pollutants, oil stains or grease.

3. Products processed by plasma cleaning machine

Metal, PE, PP, PVF2, PVC, PT, LDPE, Teflon and other materials, connectors, wires, glass lenses, automotive shutters and neon lamps, halogen mirror reflector processing, etc.

4. Plasma cleaning machine application field

Twisted Tube Heat Exchanger

Twisted Tube Heat Exchanger is to strengthen the turbulence of the flowing gas/fluid, so that the gas and the tube wall contact thoroughly. In addition to enhancing heat transfer, the twisted tube heat exchanger also has the advantages of reducing scaling, self-supporting between tube bundles, no baffle plate elements and so on.


With that being said, novel Twisted Tube Heat Exchanger is much more efficient than conventional tubular heat exchanger, or Shell And Tube Heat Exchanger. Twisted tube heat exchangers are also used in applications where the fluids are corrosive or contain particulates, as they are better able to handle these conditions than other types of shell and tube heat exchangers or Air Heat Exchanger.


Twisted tube heat exchangers are constructed from a series of twisted tubes arranged around a central tube. The tubes are twisted in such a way that the fluid will change direction multiple times as it passes through the exchanger. This increases the turbulence of the fluid and creates a larger surface area for the heat exchange, which increases the efficiency of the exchanger.


The shell is usually made from a thick metal such as carbon steel, which increases the durability of the exchanger.
