Standardized Magnetic Foreign Matter Detection Solution by Jinrongyuan

I. Precision Magnetic Bars Compliant with National Standards

1. Precise Magnetic Field: Utilizes high-performance NdFeB magnets and a standard radial magnetization process to form a uniform annular magnetic field on the side of the bar. The surface magnetic field intensity at the central point is precisely set at 6000 Gauss (internal control precision ±3%, superior to the national standard ±5%), ensuring stable and comparable adsorption force.

2. Clean Encapsulation: The magnetic core is fully sealed and encapsulated with high-purity PTFE, achieving zero contamination and zero residue. Standard specifications (approximately 18mm diameter, 50mm length) ensure methodological compatibility.

3. Full Traceability: Each magnetic bar has a unique serial number and an independent calibration certificate, enabling complete quality traceability.

II. Standardized Intelligent Pretreatment

1. National Standard Modes: Features core modes at 100 RPM (for anode materials) or 180 RPM (for cathode materials), with customizable settings to accurately reproduce the friction conditions specified in national standards.

2. Clean and Reliable: Fully enclosed operation; all contact components are made of non-magnetic materials to prevent secondary contamination. Operates quietly with low noise levels.

3. Flexible and Versatile: Offers multi-axis configurations and various material tumbling bottles. Beyond standard friction-based excitation, it can also be used for sample mixing, grinding, etc., improving equipment utilization.

III. Solution Advantages and Applications

1. Compliant and Efficient: Fully compliant with core national standards such as GB/T 24533 and GB/T 38887. Process standardization significantly enhances detection efficiency and data reliability.

2. Broad Applicability: In addition to lithium battery materials, it has been successfully applied in fields requiring precise control of magnetic impurities, such as non-ferrous metals and specialty chemicals.
