Research on spraying surface modification coating of magnesium alloy plasma cleaner

Research on spraying surface modification coating of magnesium alloy plasma cleaner

Research on spraying surface modification coating of magnesium alloy plasma cleaner: Magnesium alloys have low density, high specific strength and specific stiffness, and have extremely important application value and broad application prospects in aerospace, transportation, 3C products (communication and computing) and other industries. In addition, magnesium alloy also has good biocompatibility, mechanical compatibility and degradability as a new type of biomedical implant material and has also received extensive attention. Although magnesium alloy has outstanding advantages, it has low wear resistance and poor corrosion resistance, which limits its application to a certain extent. Therefore, improving the corrosion resistance and wear resistance of magnesium alloys under different working conditions is a problem that must be solved to expand its application. The surface modification technology of plasma cleaners can increase the surface hardness, improve corrosion resistance, and enhance wear resistance by adjusting the composition and structure of the modified surface without affecting the strength of the material. Appropriate surface modification treatment of magnesium alloys is of great significance for exerting the performance advantages of magnesium alloys. Plasma cleaning machine spraying technology has the advantages of high productivity, fine coating structure, high bonding strength with substrate, low porosity, wide sources of spraying materials, and low cost, making it suitable for traditional fields such as wear-resistant coatings and corrosion-resistant coatings. The application is more extensive. Due to the differences in physical and chemical properties between the magnesium alloy substrate and the ceramic coating, residual stresses will be generated during the preparation of the coating, which will reduce the bonding strength between the substrate coatings and affect the overall performance. The metal/ceramic gradient coating sprayed by the plasma cleaner uses the metal phase as the transition layer and the ceramic phase as the surface layer, or as the thickness of the coating increases, the content of the ceramic phase gradually increases and the content of the metal phase decreases accordingly, which is a good solution. The problem of the mismatch of metal and ceramic properties. It greatly reduces or eliminates the stress in the coating and improves the bonding strength between the coating and the substrate. Plasma cleaner spraying technology prepares modified coatings on the surface of magnesium alloys, which greatly improves the surface hardness, wear resistance and corrosion resistance of magnesium alloys, and expands the application range of magnesium alloys.

What are the differences before and after processing the mobile phone shell antenna by the atmospheric rotating plasma cleaner

What are the differences before and after processing the mobile phone shell antenna by the atmospheric rotating plasma cleaner

What are the differences before and after processing the mobile phone shell antenna by the atmospheric rotating plasma cleaner: In today’s smart phone market, whether it’s a high-end smart phone or a cost-effective, affordable smart phone, many of its components will use the surface treatment process of an atmospheric rotating plasma cleaning machine, just to name a few, such as touch screens, PCBs, speakers , Buttons, shells, batteries, etc., their mobile phone shells have insufficient adhesion and poor wear resistance; mobile phone antennas are not firmly bonded, and are prone to delamination and cracking. These components will use atmospheric rotating plasma during production, processing and assembly. Cleaning machine processing technology, next we use the mobile phone shell and mobile phone antenna to understand what effect the surface treatment process of the atmospheric rotary plasma cleaning machine has on it. The plasma surface treatment technology of the plasma cleaner can not only clean the surface organic matter of plastic, metal, glass, ceramics and other materials, but also remove the plasma surface activation on the surface of the mobile phone shell, effectively improving the bonding of the mobile phone shell during the printing and coating process. The effect is that the coating between the shell and the substrate can be firmly bonded, thereby solving the problem of weak bonding. In addition, after plasma treatment, the coating of the mobile phone shell will be very uniform, and the appearance will be more beautiful and beautiful. The wear resistance will also be greatly improved, and the paint will not be rubbed for a long time. After the mobile phone antenna is treated with an atmospheric rotary plasma cleaner, the reliability of the bonding is improved, and the problem of delamination or cracks in the bonding of the mobile phone antenna is solved. The bonding of mobile phone antennas is realized between two or more different materials. The general process is to glue glue to the surface of the substrate, and then glue the FPC to solidify it. Due to the large amount of dirt on the surface of the substrate, there are fine particles before bonding and curing, or the surface energy of the substrate itself is low, so the bonding effect is not ideal and the reliability is difficult to guarantee. In the actual production process, delamination and Crack phenomenon. The plasma surface treatment process of the atmospheric rotary plasma cleaning machine can effectively clean and activate the surface of the substrate, improve the bonding performance, improve the reliability of bonding, and solve the problem that the mobile phone antenna is not easy to bond and fall off.

Surface plasma treatment equipment low-temperature nitrogen plasma modified PAN film and its anti-pollution properties

Surface plasma treatment equipment low-temperature nitrogen plasma modified PAN film and its anti-pollution properties

Surface plasma treatment equipment low-temperature nitrogen plasma modified PAN film and its anti-pollution properties: With the rapid development of membrane science and technology, it is difficult for a single membrane material to meet actual needs, such as chemical stability, corrosion resistance, hydrophilicity, and pollution resistance. Therefore, it is necessary to physically or chemically modify the membrane material to improve Its comprehensive performance. Polyacrylonitrile (PAN) has become a widely used ultrafiltration membrane material because of its excellent chemical stability, thermal stability and bacterial resistance. It has entered the practical stage in the fields of food, pharmaceutical fermentation, oil-water separation, emulsion concentration, and paint recovery. 　　 However, because the polyacrylonitrile membrane has poor hydrophilicity and is easily contaminated by macromolecules such as protein solutions, it is imperative to modify the polyacrylonitrile membrane to improve its separation efficiency, performance and extend its service life. Surface plasma treatment equipment Plasma is a gaseous treatment technology that combines physics and chemistry. It acts in the nanometer range of the surface of the membrane material and does not affect the body characteristics of the membrane. The modification process is pollution-free and simple and quick to operate. It has been obtained in the society Rapid development. Surface plasma treatment equipment low-temperature plasma modified membrane, the flow of clean water increased, the Zeta potential of the membrane surface and membrane pores increased by 69.4% and 58.66%, respectively, the surface plasma treatment equipment low-temperature plasma technology surface modified polyacrylonitrile ( PAN) ultrafiltration membrane, and vapor phase grafted acrylic monomer (AA) method to improve the anti-fouling performance of the membrane. 　　Using atmospheric pressure dielectric barrier discharge plasma technology, the surface of the polyacrylonitrile ultrafiltration membrane is grafted with acrylic acid and polyethylene glycol methacrylate containing hydrophilic groups to obtain a hydrophilic ultrafiltration membrane. The ultrafiltration membrane modified by DBD plasma has good anti-biological pollution performance. 　　 Under normal circumstances, the surface of the ultrafiltration membrane contains hydrophilic groups, the better the wettability of the membrane. As the discharge power gradually increased, the contact angle also increased and showed regular changes. This may be because with the increase of the discharge power, the dissociation degree and average energy of plasma active particles (free electrons, positive and negative ions, metastable atoms, free radicals, etc.) have increased, which is caused by the interaction with the film surface. The more active sites, the enhanced modification effect. 　　Using surface plasma treatment equipment low temperature plasma modification to introduce hydrophilic groups on the surface of the membrane, the contact angle is reduced, and the hydrophilic properties of the PAN super membrane are improved. However, due to the poor timeliness of the plasma-modified ultrafiltration membrane, its hydrophilic properties will gradually decrease with time. Therefore, in order to overcome this shortcoming, gas phase grafting of acrylic monomers (AA) with hydrophilic structure is adopted, and the graft polymerization is carried out in the form of covalent bonds on the surface of the membrane, which can not only attract hydrophilic groups but also overcome the timeliness. , So that the ultrafiltration membrane can maintain its anti-pollution performance for a long time after modification.
