Surface modification treatment of inorganic and organic materials by plasma surface cleaning system

Surface modification treatment of inorganic and organic materials by plasma surface cleaning system

Surface modification treatment of inorganic and organic materials by plasma surface cleaning system: Due to the in-depth development and application of porous materials, more and more porous materials use plasma surface cleaning system for surface modification. Today, we mainly introduce the surface modification technology of plasma surface cleaning system, and introduce some application examples in combination with the actual situation for everyone For reference, I hope it helps everyone. This article takes porous silicon materials and activated carbon materials as examples to introduce the surface modification treatment technology of organic and inorganic porous materials. 1. Porous silicon material: The plasma surface cleaning system uses nitrogen plasma to plasma-modify the porous silicon material, which can maintain the pore structure of the porous silicon material, improve the light transmission effect, and reduce the light absorption loss. At the same time, it will also have a certain impact on the internal silicon atoms. In terms of refractive index, plasma surface modification will have a certain impact on it. 2. Activated carbon material: The plasma surface cleaning system is used to modify the granular activated carbon. Although the surface area of ​​the activated carbon is reduced, the number of macropores on the surface will be increased, and the concentration of surface acidic functional groups will be increased to make it more resistant to metal ions such as copper ions and zinc ions. Increase the adsorption capacity of the material, thereby increasing the adsorption capacity of the material: Used for organic porous materials, including but not limited to the following aspects. 1. Porous ultrafiltration high polymer film: The use of plasma surface cleaning system to treat porous ultrafiltration polymer membranes can increase the surface tension and hydrophilicity of the membranes, improve the filtration performance of the ultrafiltration membranes for buffers and protein components, and improve the filtration indicators of the membranes. Through plasma surface modification, the pore size and porosity of the ultrafiltration membrane can be increased. 2. Two or more synthetic fiber materials: The plasma surface cleaning system is used to oxidize the surface of synthetic fiber materials, which can increase the oxygen content on the surface of the fiber and enhance the hydrophilicity of the fiber. In addition, in the plasma, high-energy ions will bombard the surface of the fiber, which may slightly decrease its tensile strength. If you want to know more, please feel free to inquire at any time, and we will answer all kinds of questions about material design and craftsmanship for free.

The application of plasma cleaning machine effectively increases the product yield to 99.8% and reduces waste

The application of plasma cleaning machine effectively increases the product yield to 99.8% and reduces waste

The application of plasma cleaning machine effectively increases the product yield to 99.8% and reduces waste products: The plasma cleaner processes the surface, and the surface can be cleaned or activated according to the process and product. Both can make the coating adhere better, and have a direct impact on the cost, efficiency, product safety and product quality of the process. In the vacuum coating process of plastics, the application of plasma cleaners effectively reduces the rejection rate and improves the product yield. In the plastic vacuum coating process, plasma treatment can effectively improve the adhesion of the metal cathode sputtering coating. Make the plastic surface treatment uniform, and at the same time can remove dust and other particles on it. After cleaning, the quality of the finished product is obviously improved, and the defective rate is reduced. The user can use the ionic body to remove static electricity to achieve a cleaning effect. At the same time, the high-speed movement of the material particles in the plasma enhances this effect, so that the dust attached to the surface of the product can be effectively removed. It is also possible to selectively clean the sprayed coating through a highly concentrated plasma beam and an appropriate processing speed. The atmospheric pressure plasma technology aims to generate uncharged atmospheric plasma for surface treatment. The core components of the plasma system are plasma spray gun and plasma generator. Atmospheric plasma is generated by high-voltage discharge in the plasma spray gun, and the plasma is gathered along the discharge path through the gas flow, and directed to the surface of the material to be processed through the spray gun head. The spray gun confines the arc charged by the plasma stream to the nozzle. The nozzle also determines the geometry of the plasma beam. Plasma activates the surface through an oxidation process and removes static electricity on the surface at the same time, achieving a fine cleaning effect. Christian Busker, a master of engineering and engineer, explained: "The activated surface can improve the quality of adhesion." This process can be used for surface treatment of metals, plastics, ceramics and glass. If you want to know more, please feel free to inquire at any time, and we will answer all kinds of questions about material design and craftsmanship for free.

Low-temperature plasma processor technology improves the water absorption performance of PET clean cloth

Low-temperature plasma processor technology improves the water absorption performance of PET clean cloth

Low-temperature plasma processor technology improves the water absorption performance of PET clean cloth: The low-temperature plasma processor process can improve the water absorption performance of the PET clean cloth. What is the effect of the low-temperature plasma processor and the improvement of the water absorption performance of the PET clean cloth? Keep looking down! 1. The PET-type dust-free cloth is made of hydrophobic material before surface modification: Before surface modification, PET dust-free cloth and other PET materials generally exhibit hydrophobicity. In order to facilitate observation, we use a micro syringe to inject blue transparent reagent solutions of different sizes on the PET dust-free cloth. The particles in the reagent solution are clearly scattered on the PET dust-free cloth and are not easy to unfold, which means that the dust-free cloth absorbs water. Performance is poor. 2. The treated PET dust-free cloth has water absorption performance: After the low-temperature plasma processor is processed, the dust-free cloth is placed on the table, and then the blue transparent reagent solution is poured on the dust-free cloth. At this time, the reagent solution can be quickly spread on the PET dust-free cloth. At this time, the PET dust-free cloth The water absorption is significantly higher than before plasma surface treatment. 3. The role played by the low-temperature plasma processor: By comparing the hydrophilicity and hydrophobicity of clean cloth before and after treatment, it can be known that plasma surface modification treatment can effectively improve the water absorption of PET clean cloth, and low temperature plasma processor is in the process of plasma surface modification treatment. The activation and etching play an important role.

What are the characteristics of the glow discharge potential and light zone distribution of the plasma cleaner

What are the characteristics of the glow discharge potential and light zone distribution of the plasma cleaner

The previous article briefly introduced the glow discharge forms of vacuum and atmospheric plasma cleaners. The following mainly introduces the potential distribution and light area distribution of the plasma cleaners glow discharge. A distinctive feature of the glow discharge of the plasma cleaner is that the potential distribution in the gas is represented by the cathode drop. This is due to the effect of space charge, and the glow discharge has a large cathode drop. The surface of the cathode is covered with glow, and it is positively related to the discharge phenomenon. The current intensity is proportional to the current intensity in the tube. When the current changes, the current density and the cathode potential drop remain unchanged. At this time, it is a normal glow discharge. During the current rise process where the entire cathode is covered by glow, with the rise of current intensity and current density, the cathode drop begins to increase, and at this time it enters an abnormal glow discharge state. According to the spatial distribution of the plasma cleaning machine, it can be divided into two main areas: one is the cathode area of ​​the discharge, including the Aston dark zone, the cathode glow zone, the negative glow zone and the Faraday dark zone; It is the anode area, including the positive column area, the anode dark area and the anode glow area. The cathode part does not have plasma characteristics, and the discharge area from the positive column area to the anode is in a plasma state. The number density of positive ions is constant in the glow discharge cathode region of ordinary plasma cleaners. The increase in current density will cause the distortion of the electric field to further increase the cathode potential when entering the abnormal glow region, and the power loss in the cathode potential region will increase, which will lead to sputtering on the cathode. Cathode sputtering is a special process on the glow discharge cathode. It can remove the adhesion layer with different properties on the cathode surface and make the metal film adhere to the metal, glass, ceramic, mica and other materials.

Linear automatic plasma cleaning machine improves the bonding force of PI polyimide sputtering copper plating

Linear automatic plasma cleaning machine improves the bonding force of PI polyimide sputtering copper plating

Linear automatic plasma cleaning machine improves the bonding force of PI polyimide sputtering copper plating: PI polyimide material is one of the important materials in the preparation of FPC, but the surface of polyimide material has poor hydrophilicity and poor bonding strength with copper film, which greatly affects the quality of FPC products. How does the automatic plasma cleaner solve the problem of poor bonding strength between polyimide material and copper film! On the linear automatic plasma cleaner, oxygen or argon plasma can physically bombard the PI surface, changing the surface from smooth to rough, thereby increasing the surface area combined with the copper film and increasing the free energy of the polyimide surface. When bombarded with argon plasma, certain chemical bonds on the surface of the PI material can be broken, so that some of them overlap to form chemical crosslinks, and the other part is combined with metal atoms, which is beneficial to improve the bonding force of the sputtered copper film. The linear automatic plasma cleaner introduces a large number of hydrophilic compounds, and uses an oxygen plasma cleaner to treat the PI substrate. After plasma activation, a large number of hydrophilic hydroxyl groups can be generated on the surface of the PI substrate to improve the hydrophilicity of the PI substrate. When magnetron sputtering copper produces hydroxyl, it can react with copper to generate Cu-O bond, which enhances the bonding force between copper and polyimide.

Plasma treatment of PP fiber composite interface with low temperature plasma treatment instrument

Plasma treatment of PP fiber composite interface with low temperature plasma treatment instrument

Plasma treatment of PP fiber composite interface with low temperature plasma treatment instrument: The advantage of using dielectric barrier discharge (DBD) for plasma treatment of 　　 low temperature plasma treatment instrument is that the working environment of the plasma it generates can be close to or equal to atmospheric pressure. Moreover, one or two kinds of media can be used to make electrodes into various shapes, which can be used in practical work under different frequencies. Specific dielectric barrier discharge is a powerful tool to improve the surface properties of polymer materials. Compared with the discharge generated by continuous sinusoidal voltage, the repetitive pulse voltage it uses is more conducive to improving the statistical distribution and sensitivity of microdischarges. Routine handling of materials. 　　 At the same time, DBD has better uniformity than corona discharge plasma treatment under atmospheric pressure. In addition, since DBD is a discharge technology under atmospheric pressure, a relatively complicated vacuum system is not required. Therefore, it is particularly suitable for industrialized continuous processing and its application prospects are very broad. 　　The interface characteristics between the fiber and the matrix is ​​one of the key factors that determine the overall performance of the fiber-reinforced composite material. In most fiber-reinforced composite materials, there is a huge difference in performance between the fiber and the matrix as the reinforcing material, and the compatibility between the two is quite limited, so the bonding of the interface is often weak. 　　 Therefore, in the actual material processing process, the fiber surface must be properly treated to improve the interface performance of the composite material. Among the many surface treatment methods, the plasma treatment of the low temperature plasma treatment instrument attracts attention for its high efficiency, low energy consumption and no pollution. 　　 The surface of the fiber that has not been treated by the low-temperature plasma treatment device DBD is very smooth, but after the plasma treatment, the surface of the fiber quickly becomes rough and pits are formed. As the treatment time increases, the roughness of the fiber surface increases, and the etching effect becomes more obvious. 　　 Low-temperature plasma treatment instrument DBD plasma treatment increases the roughness of the fiber surface, the interface bonding between the fiber and the matrix and the friction when pulling out, and the average pulling force increases. 　　 Low temperature plasma treatment instrument DBD plasma treatment process, oxygen implants on the surface of the fiber, and combines with the carbon atoms of the fiber to form different active groups, which is conducive to the interface bonding between the fiber and the matrix.
