The plasma cleaning machine can remove the dirt on the surface of the magnetic steel to improve the bonding effect

The plasma cleaning machine can remove the dirt on the surface of the magnetic steel to improve the bonding effect:         There are many types of small magnetic steel products, which have a wide range of uses. They have high requirements for the cleanliness and bonding strength of the product surface. How can plasma cleaning machines effectively remove surface contaminants and improve bonding effects? Plasma cleaning machine         The main types of small micro-magnetic steel sheets are aluminum-cobalt magnetic steel, rare earth strong magnetic (neodymium iron boron) bonded rare earth permanent magnetic steel, ferrite magnetic steel, etc., which have been widely used in smartphone acoustic devices, such as speakers, earphones, Microphones, etc., as well as micro-motors, air-conditioning motors, computer-driven motors, magnetic therapy products, etc. Most small magnetic steel sheets have higher requirements for product surface cleanliness, and are generally produced in dust-free workshops. In addition, there are certain requirements for product surface adhesion strength. Therefore, is there a more reliable method to remove the contaminants on the surface of the magnetic steel, so as to improve the effect of bonding products?         Different from cleaning in the traditional sense, the surface treatment process of the plasma cleaning machine is dry cleaning throughout the entire process, without waste water and other waste gas pollutants. The plasma cleaning machine can remove the contaminants on the surface of the magnetic steel, and at the same time form active groups on the surface of the magnetic steel to improve the morphological characteristics of the surface of the magnetic steel.         After the plasma cleaning machine is used to treat the miniature magnetic steel sheet, the surface energy of the magnetic steel sheet will change significantly, which can be assisted by the contact angle tester. In general, the smaller the water drop angle, the higher the surface energy. Conducive to obtain better bonding effect. The following is the comparison before and after plasma surface treatment of small magnet steel.         The angle of water droplets before treatment is 110.99 degrees;         The angle of the water droplets processed by the plasma cleaning machine is 32.5 degrees;         The main reasons for the different angles of water droplets before and after plasma surface treatment:         1. The cleaning function of the plasma cleaning machine, which can remove organic pollutants on the surface of the magnetic steel to form a clean surface;         2. The activation effect of the cleaning equipment produces a large number of hydrophilic active groups on the surface of the magnetic steel, which improves the surface energy. At this time, the bonding is carried out as soon as possible to obtain better results.         If you want to know more, please feel free to inquire at any time, free of charge to answer your questions about the dirty surface of the material.

What are the PTFE membranes activated by ptfe membrane plasma equipment? How is the process?

What are the PTFE membranes activated by ptfe membrane plasma equipment? How is the process?

       What are the PTFE membranes activated by ptfe membrane plasma equipment? How is the process? Three surface treatment methods to improve the adhesion of PTFE membranes have different characteristics and treatment effects. Today, we will focus on the activation treatment in the ptfe membrane plasma equipment. The activation treatment of ptfe membrane plasma equipment can improve the adhesion of the PTFE membrane material surface. Which membranes can be treated with plasma equipment? So what is the whole activation process? Let us understand together.        Due to different applications and different material compositions, PTFE membranes can be divided into many different types, and which PTFE membranes can be processed by plasma equipment, this can also be said to be quite a lot, not to list them one by one, the following is PTFE Several typical materials of the membrane have been processed. , 1. PTFE film with red pigment and glass fiber added; 2. PTFE film with graphite or carbon powder added; 3. The addition of ceramic powder PTFE film. ,     Since the above PTFE membrane is the addition or compounding of other materials, it is necessary to adjust the corresponding process parameters during the activation process of the specific ptfe membrane plasma equipment. Therefore, different PTFE membranes and different treatment purposes often correspond to different process parameters, and the plasma surface treatment process has a certain flow. Let's take a certain proportion of ceramic powder into the PTFE membrane as an example to introduce to you.           The purpose of plasma surface activation of ptfe membrane plasma equipment is to process the epoxy resin and PTFE membrane before pressing, and improve the adhesion with epoxy resin. Plasma surface activation process: Put the treated PTFE membrane into the vacuum chamber of the vacuum plasma surface treatment equipment, close the door and evacuate to 20-50Pa, and pass in a certain amount of process gas to maintain a certain degree of vacuum Perform plasma discharge, set the power and processing time, and then return the gas to break after the processing is completed, then open the door of the processed PTFEP tetrafluoroethylene membrane, and take out the processed PTFEP tetrafluoroethylene membrane.        In the detection of plasma activation effect, it can be reflected by changing the angle of the contact angle of water droplets. In addition, after 1000 hours of ultraviolet light aging test, the tensile value of the treated PTFE film reached 9N/cm or more, but the UV light aging test still did not peel off, the tensile value did not change much within the specified range, after the ptfe film plasma equipment plasma After surface activation, the bonding effect is qualified.

The effect of plasma modification on the surface chemical structure of activated carbon fibers

The effect of plasma modification on the surface chemical structure of activated carbon fibers: Activated carbon fiber (ACF) is a new type of fibrous adsorbent formed by carbonized activated organic fibers. The adsorption and catalytic performance of activated carbon fiber is closely related to its surface area and surface chemical properties. For a long time, many studies have explored various modification methods to increase the specific surface area of ​​activated carbon fibers and enhance the activity of surface functional groups to achieve the purpose of improving the adsorption performance of activated carbon fibers. Plasma modification technology is a material surface modification technology that has developed rapidly in recent years. Plasma modification is to generate a large number of charged particles, excited particles, photons, free radicals and other plasmas in the dielectric barrier discharge. These high-energy plasmas are used to hit the surface of the material to change the physical and chemical properties of the material surface without destroying the surface characteristics of the material, thereby improving the specific surface area, pore size, pore volume, surface functional group and other related properties of the material. Compared with other surface modification technologies, plasma modification mainly has the advantages of no secondary pollution and no damage to the surface characteristics of the material. In addition, the plasma modification technology has many forms of action on the surface of the material, and the process has a wide range of applications, which is convenient for continuous automation. produce. Different discharge voltages have different effects on the surface modification of ACF. The discharge time affects the modification results, and the ACF surface active substances increase with the modification time. Plasma-modified ACF can effectively introduce nitrogen-containing functional groups to its surface, and change the morphological distribution of oxygen-containing functional groups to a certain extent, so that the basic groups on the surface of ACF and the oxidizing ability have been greatly improved, so ACF The content of basic active sites on the surface increases, and the chemical adsorption performance is greatly improved. This is of great positive significance for desulfurization and denitrification. Effect of Plasma Modification on the Surface Chemical Structure of Activated Carbon Fiber

What effect does the sputtering phenomenon of the vacuum plasma processor have on the product

What effect does the sputtering phenomenon of the vacuum plasma processor have on the product

What effect does the sputtering phenomenon of the vacuum plasma processor have on the product: When using a compatible coupling discharge vacuum plasma processor for surface treatment of material plasma, as long as the selected gas is an inert gas, a certain sputtering phenomenon will occur, which is actually independent of DC glow discharge or AC high-frequency discharge , Then does the sputtering phenomenon affect the products processed by the vacuum plasma processor? The sputtering phenomenon produced by the vacuum plasma processor is generally weak. For general products or materials, this weak sputtering phenomenon will not affect the performance of the substrate, but if the processed product has strict processing requirements, For medical-related products, the degree of sputtering of the substrate is required. Generally, the less sputtering, the weaker the better. From the electrode structure of the vacuum plasma processor, we understand the sputtering, compatible coupling radio frequency vacuum plasma surface treatment equipment, basically use aluminum alloy as the electrode, this is mainly because aluminum itself has good heat dissipation, and It has good weather resistance to plasma. Even if it is aluminum, aluminum atoms will still escape from the electrode surface under long-term plasma bombardment. Similarly, because radio frequency sputtering will bombard metal particles, the metal particles that are bombarded may adhere to the surface of the product, causing pollution, and then affecting the product. For example, the metal atoms on the surface of medical polymers will bring the body to the human body. Safety hazards; the semiconductor lead frame will affect the wire bonding quality of the product due to the injection of metal. Therefore, in order to reduce or even avoid the phenomenon of radio frequency splashing, it is necessary to adjust and optimize the cavity structure of the vacuum plasma processor, the cooling of the electrode plate, and the process parameters. We will discuss the content of this part later.

Can the plasma cleaner process powder particles? What is special

Can the plasma cleaner process powder particles? What is special: Plasma cleaning machines or plasma surface cleaning activation treatment machines are often used for plasma surface treatment of materials such as sheets, membranes, tubes or strips. Such materials are generally large in size, but in some practical applications in industrial production , It is also necessary to perform plasma surface cleaning and activation treatment on irregular small plastic metal parts, powder particles, etc. Plasma cleaners for processing powder particles are called rotary drum plasma cleaners in the industry. Depending on the processing materials and operating characteristics, there are also powder or powder plasma surface activation treatment equipment, drum plasma machines. A plasma machine with a rotating drum structure is similar in internal structure to a domestic drum washing machine. The items placed in the plasma cavity are constantly tumbling and stirring, thereby reacting with the plasma in the equipment to achieve surface modification such as cleaning, activation, and etching. Sex. Attention points of the powder particle plasma machine cleaning machine: 1. Structure design of electrode and rotating system: The design of the electrode structure is closely related to the power supply. The key is to see whether the electrode structure is a compatible discharge form or a coupled discharge form. The rotating structure has a certain degree of stability and adaptability. The combination of the two factors affects the discharge state and processing effect of the device. All have a great impact. 2. Power selection: For power frequency, there are generally three common ones, namely IF 40KHz, RF 13.56MHz, and microwave 2.45GHz. Choose according to the adopted discharge mechanism, processing purpose, application scenario, user characteristics, equipment stability, safety and cost-effectiveness. . 3. Process parameters: For any plasma machine cleaning machine surface cleaning and activation treatment equipment, the selection of appropriate process parameters is one of its cores. The subtle differences in various parameters may lead to different surface modification effects. Usually, the corresponding plasma surface treatment solution is matched according to multiple conditions such as the processed product, material, processing purpose, and target production capacity. However, for the surface modification of the plasma of the powder particle plasma machine cleaning machine, due to the difficulty of subsequent detection, the in-depth understanding of industry and technology is also the plasma of powder particle plasma and irregular small plastic metal parts. The bulk plasma modification provides the premise and guarantee.
