⒉The mechanism of plasma plasma flame treatment machine in rubber and plastic industry products
I have found in industrial applications that some rubber and plastic parts have difficulty in bonding when they are connected to the surface. This is because polypropylene, PTFE and other rubber and plastic materials have no polarity. These materials have not undergone surface treatment. The effect of printing, bonding, coating, etc. in the state of being very poor, or even impossible.
Some processes use some chemicals to treat these stolen plastic surfaces, which can change the bonding effect of the material, but this method is not easy to master. The chemicals themselves are toxic, the operation is very troublesome, and the cost is high. The original excellent properties of plastic materials also have an impact.
Use plasma plasma flame treatment machine plasma technology to perform surface treatment on these materials. Under the bombardment of high-speed and high-energy plasma, the surface of these materials can be enlarged, and an active layer is formed on the surface of the material, so that rubber and plastic can be processed. Printing, bonding, coating and other operations. The application of plasma technology to the surface treatment of rubber and plastic has simple operation, no harmful substances before and after treatment, good treatment effect, high efficiency and low operating cost.
3. The role of plasma plasma flame treatment machine to clean tiny holes
With the miniaturization of the diameter of the HD plate, the traditional chemical cleaning process can no longer meet the cleaning of the blind hole structure. The surface tension of the liquid makes it difficult for the liquid to penetrate into the hole, especially when processing the laser drilled micro blind hole plate. It is not good. Currently, the main hole cleaning processes used in micro-holes include ultrasonic cleaning and plasma cleaning. Ultrasonic cleaning is mainly based on the cavitation effect to achieve the purpose of cleaning. It belongs to wet processing, and the cleaning time is longer and depends on the cleaning. The decontamination performance of the liquid increases the problem of the disposal of the waste liquid.
The commonly used process at this stage is mainly the plasma cleaning process of plasma plasma flame treatment machine. The plasma treatment process is simple, environmentally friendly, and has obvious cleaning effects. It is very effective for blind hole structures.
Plasma cleaning refers to the directional movement of highly activated plasma under the action of an electric field, and a gas-solidification reaction with the drilling dirt on the hole wall. At the same time, the generated gas products and some unreacted particles are discharged by the air pump. Plasma is generally divided into three steps when cleaning the blind holes of HD boards. In the first stage, high-purity N2 is used to generate plasma, while the printed board is preheated to make the polymer material in a certain activated state; the second stage is with O2, CF4 is the original gas. After mixing, it produces 0, F plasma, which reacts with acrylic acid, PI, FR4, glass fiber, etc., to achieve the purpose of de-drilling; the third stage uses O2 as the original gas, and the generated plasma and reaction residues Make the hole wall clean.
In the plasma cleaning process, in addition to the plasma chemical reaction, the plasma of the plasma plasma flame treatment machine also physically reacts with the surface of the material. The plasma particles knock off the atoms on the surface of the material or the atoms on the surface of the attached material, which is helpful for cleaning the etching reaction.
With the development of materials and technology, the realization of the buried straight hole structure will become smaller and more refined; when the blind hole is electroplated and filled, it will be more and more difficult to use the traditional chemical de-smear method , And the cleaning method of plasma treatment can well overcome the shortcomings of wet desmears, can achieve a better cleaning effect on blind holes and micro holes, so as to ensure that a good effect is achieved when the blind holes are electroplated and filled.
4. Plasma plasma flame treatment machine technology is applied to the treatment of ignition coils
With the development of the automotive industry, its performance requirements in all aspects are getting higher and higher. Ignition wire casting can improve power, and the obvious effect is to improve the low-to-medium-speed torque when traveling; eliminate carbon deposits, better protect the engine, and extend the life of the engine; reduce or eliminate the resonance of the engine; fully burn the fuel and reduce emissions, etc. Many functions. To make the ignition wire fully play its role, its quality, reliability, service life and other requirements must meet the standards, but the current ignition coil production process still has a big problem-after the ignition coil frame is poured with epoxy resin, Because the skeleton contains volatile oil stains on the front surface of the mold, the bonding between the skeleton and the epoxy resin is not reliable. When the finished product is used, the temperature rises at the moment of ignition, which will cause bubbles and damage in the tiny gaps on the bonding surface. Ignition coils may explode in serious cases.
After the ignition coil skeleton is plasma treated by a plasma plasma flame treatment machine, it can not only remove the hardly volatile oil on the surface, but also greatly improve the surface activity of the skeleton, that is, it can improve the bonding strength of the skeleton and the epoxy resin, avoid the generation of bubbles, and at the same time Improve the welding strength between the enameled wire and the skeleton contact after winding. As a result, the performance of the ignition coil in all aspects of the production process is significantly improved, and the reliability and service life are improved.
The major feature of plasma cleaning technology of plasma plasma flame treatment machine is that regardless of the type of substrate to be treated, it can be processed. It can treat metals, semiconductors, oxides and most polymer materials, such as polypropylene, polyester, and polyamide. Imine, polyvinyl chloride, epoxy, and even polytetrafluoroethylene can be handled well, and can be used to clean the whole, part and complex structure. The application of plasma cleaning technology has matured first, and its related output value has increased year by year. The output value of foreign markets is higher than that of the domestic market, but the domestic development space is large and the application prospects are attractive.
