No matter how much it contains, it can be recycled. Yuan Jinggui Metal has been engaged in refining precious metals for many years. Ceramic tile center has the most advanced precious metal recycling technology talents in R&D, and has successfully applied for a number of patented technologies for the company. At the same time, we developed our own fully enclosed automatic recycling equipment. In the recycling process,
Introduction:
Minimize the environmental pollution caused by many precious metals, and carry out safe and harmless treatment to the maximum extent. Palladium alloys can be made into films (called palladium films). The thickness of palladium membrane is usually about 0. 1mm, which is mainly used for the separation of hydrogen and impurities. The principle of purifying hydrogen by palladium membrane is that hydrogen to be purified is introduced into one side of palladium membrane at 300 ~ 500℃.
Hydrogen is adsorbed on the wall of palladium film. Because the 4d electron layer of palladium lacks two electrons, it can form an unstable chemical bond with hydrogen. The reaction between palladium and hydrogen is reversible. Under the action of palladium, hydrogen is ionized into protons with a radius of 1.5 10 15m. The lattice of palladium is constant, so it can pass through the palladium membrane, and the protons combine with electrons under the action of palladium to form hydrogen molecules again.
