Shandong Huafeng Steel Pipe Co., Ltd. is a professional seamless steel pipe, steel pipe, precision steel, special steel pipe, welded pipe production and sales of the modern enterprise. Palladium tube purified hydrogen principle is 20cr steel, at 300-500 ℃, to be purified is passed into the hydrogen side of the tube when the palladium, hydrogen is adsorbed on palladium 20cr wall steel prices, due to the lack of palladium 4d electron shell two electrons, palladium can generate an unstable chemical bond (this reaction is hydrogen with palladium is reversible) 20cr steel production plant, under the action of palladium, hydrogen is ionized proton radius of 1.5 × 1015m and hydrogen, and The lattice constant of 3.88 × 10-10m (20 ℃ time), it can be through the palladium tube, under the action of palladium in combination with a proton and electron and re-formation of hydrogen molecules 20cr steel company, to escape from the other side of the palladium tube . Palladium tube surface, not the dissociated gas impermeable, it is possible to obtain high purity hydrogen utilizing palladium tube. Shandong Huafeng Steel Pipe Co., Ltd. is a professional seamless steel pipe, steel pipe, precision steel, special steel pipe, welded pipe production and sales of the modern enterprise.
