What role does atmospheric plasma cleaning equipment play in the production of lithium battery pole pieces

What role does atmospheric plasma cleaning equipment play in the production of lithium battery pole pieces

What role does atmospheric plasma cleaning equipment play in the production of lithium battery pole pieces: When it comes to automotive lithium batteries, I believe everyone is no longer unfamiliar with them. The production process of automotive lithium battery pole pieces is more complicated, including slurry preparation, slurry coating, pole piece rolling, pole piece slitting and pole piece drying. It is a relatively new process to use atmospheric plasma cleaning equipment to process the pole pieces before coating. Therefore, what role does atmospheric plasma cleaning equipment play in the manufacturing process of lithium battery positive and negative plates? How does this help the product? The positive and negative electrode materials of the lithium battery are coated on the metal film to make the positive and negative electrodes of the automobile power lithium battery. Before the electrode material is coated, the metal film must be cleaned to improve the coating effect. The material of the metal film is generally aluminum foil or copper foil. In the past, the cleaning is done by wet processing. Even if the surface is cleaned with ethanol and other solutions, this cleaning method is likely to cause invisible damage to the lithium battery and other components. Will produce some residue. Due to these shortcomings, in the subsequent manufacturing process, the dry surface treatment method of atmospheric plasma cleaning equipment is gradually adopted. It can not only remove organic matter, make the surface of the film rough, improve the wettability of the metal film surface, but also improve the coating. The uniformity of the layer is conducive to improving thermal stability, safety and reliability. If you have any questions about the purchase or use of the equipment, please feel free to inquire.

Plasma bonding process and effect analysis of PDMS matrix plasma cleaning equipment

Plasma bonding process and effect analysis of PDMS matrix plasma cleaning equipment

Plasma bonding process and effect analysis of PDMS matrix plasma cleaning equipment: PDMS is a common organic polymer material. It has the characteristics of low raw material price, short production cycle, good durability, flexible packaging method and its ability to form a good seal with a variety of materials. It has many advantages in electronic medicine and other aspects. Huge application prospects. Although PDMS is widely used, PDMS has shortcomings such as high hydrophobicity and strong adsorption of non-polar substances, making PDMS unable to bond with its own glass metal flakes and other materials under normal conditions to limit its use. PDMS is cleaned by plasma on the surface of the equipment. The above operations can be achieved after modification. Plasma cleaning equipment processing is a process in which a high-frequency generator ionizes a gas in a vacuum state to generate plasma (the fourth state of the substance) for surface activation modification. Plasma is an ionized gaseous substance composed of atoms deprived of some electrons and positive and negative electrons produced by ionization of atoms. It is the fourth state of matter existing in addition to solid, liquid, and gas. These highly active particles interact with the surface of the material to be treated, activate the surface of the inert polymer to improve its hydrophilicity, enhance the interaction of the interface and make it easier for monolayer molecules to diffuse to the surface, so that the surface of the PDMS matrix can be modified Realize its bonding with a variety of materials. There are three main process parameters that affect the PDMS bonding effect in plasma cleaning equipment processing: RF power, air flow, and modification time. At present, most of the researches using oxygen as the reaction gas have found through preliminary experiments that the bonding effect of air as the reaction gas can also meet the experimental requirements. The bonding loading pressure also has a non-negligible effect on the PDMS bonding effect after plasma treatment. The PDMS PDMS bonding effect is one of the important focuses in this field. To determine the PDMS PDMS bonding effect is mainly to measure the bonding strength. The T-peel method can be used to determine the bonding strength between two PDMS films. PDMS-PDMS bonding integrity is also one of the important indicators of bonding effect. Bonding integrity is a necessary condition for the normal use of the microfluidic chip. Part of the bonding will cause the microfluidic chip to fail. Plasma cleaning equipment processing does not produce a damage layer on the surface, it is a non-destructive processing process, and the surface quality is guaranteed; because it is carried out in a vacuum, it does not pollute the environment and ensures that the cleaned surface is not polluted again, which is effective and environmentally friendly. Chengfeng Zhizao is committed to the research and development of plasma technology, if you have any questions, please feel free to consult.

On-line plasma cleaning equipment can improve the adhesion of the engine guard plate without falling off for 10 years: The engine guard plate used in the automobile industry is used to protect the engine and prolong its service life. The materials used for the engine guard plate include hard plastic, iron or manganese alloy guard plate, aluminum alloy, plastic steel guard plate, etc. In order to ensure that the engine guard plate can have a good sealing effect, the glue foaming treatment is often carried out, and the engine guard plate often encounters problems such as low surface energy of the material and poor adhesion, and the surface energy of the engine guard plate should be improved. To increase the bonding strength, it is necessary to introduce online plasma cleaning equipment for plasma treatment to improve product quality and reliability. So what is the effect of the online plasma cleaning equipment on the treatment of the engine guard plate? On-line plasma cleaning equipment has carried out actual test verification on the engine guard plate of plastic steel material. Why do we need to test the plastic engine guard plate? Due to the current selection of plastic steel materials for engine guards, it is universal. The main chemical composition of plastic materials is modified polymer, also known as modified copolymer PP. It has good rigidity, great elasticity, good corrosion resistance, good aging resistance, convenient processing, and does not hinder the settlement function when the vehicle collides. Plasma cleaning equipment has the advantages of environmental protection, low cost, etc., and is currently widely used before epoxy foaming of engine guards. Before the plastic steel engine guard plate is processed by the online plasma cleaning equipment, its original PP surface energy is relatively low. After being wetted with water, the water droplets are not easy to disperse and are in the form of hydrophobic beads. At this time, the adhesion is poor. After being processed by Chengfeng Zhizhuang's online plasma cleaning equipment, after the same wetting, the water droplets can spread out evenly. At this time, the surface energy and adhesion of PP have been significantly improved. By comparison, we can see the change of water droplets on the surface of the engine guard plate, and the bubbling and bonding effect of the plasma cleaning equipment on the engine guard plate has been improved.

Five types of cleaning machine alarms and troubleshooting for vacuum plasma equipment

Five types of cleaning machine alarms and troubleshooting for vacuum plasma equipment: Plasma equipment is a process equipment used for plasma surface treatment of materials or products, and vacuum plasma equipment is one of them. How to deal with failures or alarms during use? Now Chengfeng Zhizao has listed some common problems, hoping to help you. Pump thermal overload protection for vacuum plasma equipment: When the plasma processing equipment has vacuum pump thermal overload protection, check whether the parameters of the system have changed, because when the equipment is suddenly powered off, all the parameters of the system will be reset to zero, which will cause this kind of alarm of the plasma equipment. In the case of checking the system parameters unchanged, it is necessary to confirm whether the thermal relay is automatically protected, and press the reset button to start the vacuum generation system of the vacuum plasma processing system. If there is no automatic protection, check again whether the circuit is broken or short-circuited. If there are no abnormalities above, check the vacuum pump again. The air discharge pressure of the vacuum plasma equipment is too low: When this kind of failure occurs, it may be that the gas is not turned on or the gas is consumed too much. It is necessary to check whether the gas solenoid valve used to break the vacuum at the bottom of the cavity is working properly, and whether there is an open circuit or a short circuit. Countdown failure of vacuum plasma equipment vacuum pump: In case of failure, please check the pumping capacity of the vacuum pump first, and then press the reset button after troubleshooting. Material leakage and unclosed vacuum door will affect the pumping capacity of the vacuum pump. In addition, check each node in the plasma vacuum processing system one by one. See if there is a bad or damaged pipe connection. Alarm when CDA pressure is too low: This type of alarm is also known as the low breaking air pressure alarm. It is caused by insufficient compressed air pressure. It mainly occurs in plasma processing equipment equipped with high-vacuum pneumatic baffle valves. If this type of alarm occurs, it is necessary to check whether the CDA is normally supplied with air. Device side. Determine whether the air supply pressure is too high or too low, whether the alarm value of the pressure reducing gauge is set correctly, and check the electrical wiring. Alarm when the vacuum gauge fails: The vacuum gauge failure alarm may be caused by damage to the vacuum gauge. It is necessary to check the control circuit of the vacuum gauge to determine whether the vacuum gauge is faulty or short-circuited. The emergency stop of the vacuum plasma processing system cannot be reset or has been pressed, and the emergency stop switch needs to be turned on: At this time, check whether the emergency stop is suppressed. If not, check the emergency stop line. Chengfeng Zhizao focuses on the research and development and manufacturing of plasma technology.
