Shanghai there are new molecular sieve, Ltd. - sieve and then at a temperature of 950-1200 ℃ calcining α-alumina powder is obtained, the mother liquor can be recycled. This method was invented by Austrian scientist Bayer (K.J.Bayer) in 1888, today is still the main method of industrial production of alumina, called "Bayer." In the α-alumina lattice, the hexagonal close-packed oxygen ions, Al3 + symmetrically surrounded by oxygen ions in octahedral centers, large lattice energy, so the melting point, boiling point is very high. α-alumina is not soluble in water and acid, Features: 1, Shanghai there are new molecular sieve, Ltd. - nitrogen plant of nitrogen with full German technology and molecular sieve filling technology, to improve the recovery of the maximum molecular sieve sieve Ji'an minimum to reduce the rate of molecular sieve flour sieve, so that the whole equipment life really up to ten years. 2, Shanghai there are new molecular sieve, Ltd. - nitrogen plant combined with years of domestic and foreign counterparts in the technical characteristics of Jinggangshan molecular sieve, sieve affect life in the heart of the successful development, using the adjustable separate molecular sieve adsorption tower Jiaozhou make molecular sieve bed is always maintained in a stable, static state efforts to address the mechanical wear of the industry in the long term due to the molecular sieve pressure plant produced under load state, both to ensure the compression of the molecular sieve, but while the bulk density of molecular sieve adsorption column volume ratio correction value is zero.
