Production Process of Hydrogen-Rich Balls
1.
Raw Material Pretreatment
High-purity magnesium powder, hydrogen storage alloy powder and other core raw materials are screened and dried under inert gas protection to strictly control the moisture content below 0.05%, avoiding the risk of material oxidation and failure in subsequent processes.
2.
High-Energy Ball Milling Hydrogenation
The pretreated metal powder is put into a planetary ball mill, and high-purity hydrogen is injected into the sealed tank. Under the impact and friction of grinding balls, the metal powder fully reacts with hydrogen to form stable metal hydride particles, which is the core step to realize the hydrogen storage function.
3.
Molding & Granulation
The hydrogenated composite powder is mixed with a small amount of food-grade binder, and extruded or pelletized by a granulator to form spherical particles with uniform particle size, and the particle size is precisely controlled in the range of 3-10mm according to the application scenario.
4.
Surface Coating Treatment
A layer of porous food-grade polymer film is uniformly coated on the surface of the spherical particles. This step can control the slow-release rate of hydrogen, prevent the rapid failure of the internal hydrogen storage material caused by direct contact with water, and improve the service life of the product.
5.
Sealed Packaging & Quality Inspection
The finished hydrogen-rich balls are tested for hydrogen release performance, pressure resistance and safety, and then filled into an inert gas sealed packaging bag to isolate air and moisture, ensuring that the product will not fail during long-term storage.
