Iron powder for deoxidizer

Deoxidizer reaction principle of commonly used are: iron oxide (iron) oxide enzyme (enzyme) ascorbic acid oxidation photosensitive perceptual dye oxidation, etc., most of the currently used deoxidizer are based on the iron powder oxidation deoxidizing agent with reduced iron powder in the air can occur REDOX reaction, 4 fe2o3, fe 3 + o2 = 2 products ferric oxide has the water absorbability, so iron powder as deoxidizer and both properties of dehydration, namely desiccant appearance into colored powder pouch this iron series deoxidizer can make it, in the packaging, the oxygen concentration to 0.01%Generally, lg iron powder is required to react with 300mL oxygen. The appropriate amount can be selected according to the amount of oxygen left after packaging and the permeability of the packaging film.
