Function and Theory about the Plasma Surface Treatment Machine

Plasma cleaning machine in various industries


The mechanism of plasma technology in the rubber and plastics industry, we found in the industrial application that some rubber and plastic parts will have difficulty in bonding when the surface is connected. This is because the rubber and plastic materials such as polypropylene and PTFE have no pole. Sexually, the printing, bonding, coating, etc. of these materials in the untreated state are very ineffective or impossible.

Some processes use some chemicals to treat these rubber and plastic surfaces, which can change the bonding effect of the materials, but this method is difficult to master, the chemicals themselves are toxic, the operation is very troublesome, the cost is high, and the chemicals are for the rubber. The original excellent properties of plastic materials also have an impact. These materials are surface treated by plasma technology. Under the bombardment of high-speed and high-energy plasma, the surface of these materials can be maximized, and an active layer is formed on the surface of the material, so that rubber and plastic can be printed and bonded. Coating and other operations. The application of plasma technology to the surface treatment of rubber and plastic, its operation is simple, no harmful substances are produced before and after treatment, the treatment effect is good, the efficiency is high, and the running cost is low.

Plasma technology in the rubber and plastics industry applications of plasma surface treatment technology, including rubber, composites, glass, fabrics, metals, etc., involving all walks of life, this article we mainly introduce its in the rubber, plastics industry application. Plasma technology in the automotive industry


With the development of the automotive industry, the ignition coil has higher and higher performance requirements in all aspects. The ignition coil has lifting power, the most obvious effect is to improve the medium and low speed torque during driving; eliminate carbon deposit, better protect the engine, extend the life of the engine; reduce or eliminate the resonance of the engine; fully burn the fuel, reduce emissions, etc. Features.

In order to make the ignition coil fully play its role, its quality, reliability, service life and other requirements must meet the standard, but the current ignition coil production process still has a big problem - after the epoxy coil is cast outside the epoxy resin, due to The skeleton contains a large amount of volatile oil on the front surface of the mold, which causes the bond between the skeleton and the epoxy bond surface to be unreliable. In the finished product, the ignition temperature rises, and bubbles are generated in the small gap of the joint surface, and the ignition coil is damaged. Serious explosions can also occur.

After the plasma treatment of the ignition coil skeleton, not only the non-volatile oil stain on the surface can be removed, but also the surface activity of the skeleton can be greatly improved, that is, the adhesion strength between the skeleton and the epoxy resin can be improved, bubbles can be avoided, and the enameled wire after winding can be improved. Welding strength with the skeleton contacts. In this way, the performance of the ignition coil in various aspects of the production process is significantly improved, improving reliability and service life.

The engine oil seal engine crankshaft oil seal prevents engine oil from leaking from the engine and prevents foreign matter from entering the engine. The crankshaft oil seal is one of the parts of the engine and is in contact with the oil at a high temperature, so it is necessary to use a material excellent in heat resistance and oil resistance. At present, high-grade cars generally use PTFE materials. With the continuous improvement of automotive performance requirements, more and more manufacturers have gradually used this material, and its application prospects are very broad.

  

PTFE material has excellent performance in all aspects, high temperature resistance, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties, low coefficient of friction, but untreated PTFE material has poor surface activity, one end and metal The bonding between the two is very difficult and the product cannot meet the quality requirements. In order to solve this technical problem, it is necessary to change the surface properties of PTFE (polytetrafluoroethylene) and metal bonding, without affecting the performance of the other side.

Although the treatment with the sodium solution in the industry can improve the bonding effect to a certain extent, it changes the performance of the original PTFE. It has been proved by experiments that after the surface of the PTFE to be bonded is bombarded with plasma, the surface activity is obviously enhanced, the bonding with the metal is firm and reliable, and the requirements of the process are satisfied, while the other side maintains the original performance, and its application is also More and more widely recognized.
