(Summary description)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.
