Corrosion works as follows: aluminum, is an amphoteric metal, both, but with a base and an acid, oxides, too, Ningguo molecular sieves, while aluminum surface trace metal ions presence would catalyze the oxidation of aluminum is, though Due to the relatively dry gas, such catalytic slow progress, however, trace moisture in high concentration, can cause irreversible damage to the surface of aluminum oxide film: If desiccant is calcium chloride, will have the following ionization reaction: Thus, over time, the molecular sieve, the surface of the aluminum oxide film was completely destroyed, a new dense protective oxide film due to the presence of ions can not be formed, so that the aluminum strip will slowly corrode, salted form, the final form cracks and voids, resulting in failure of insulating glass. Aluminum is amphoteric metal, regardless of the drying agent having basic or acidic characteristics, it can be etched with the reaction, because after the formation of the water-absorbing calcium hydroxide, calcium oxide, pyrophosphate is formed after the absorption of phosphorus pentoxide. As the most advanced air separation oxygen sieve adsorbents, Bozhou sieve, LiLSX sieve having a large nitrogen adsorption capacity, oxygen and nitrogen separation coefficient, and high recovery rate. However, for technical reasons, China's long-term dependence on imported LiLSX molecular sieve product. Luoyang Jianlong Zeolite to develop LiLSX began in 2005, after six years, relying on independent innovation, Luoyang Jianlong number of breakthroughs in core technology bottlenecks, a total of 11 patent applications, to become the world's first six master the production technology business. _ _ New molecular sieve zeolite molecular sieves by the Shanghai Bozhou new molecular sieve Limited. Zeolite molecular sieve _ new _ Bozhou new molecular sieve zeolite is Shanghai Co.
