Production Method of Oxygen Molecular Sieve OX480:
Prepare raw materials
The production of OX480 requires the preparation of raw materials such as sodium silicate, sodium hydroxide, sodium sulfate, and activated alumina. Among them, sodium silicate is the main raw material, which can be obtained by hydrothermal synthesis. Sodium hydroxide and sodium sulfate are additives used to regulate the pH and ion concentration of the solution. Activated alumina is a carrier material that can provide a high specific surface area and suitable pore structure for oxygen molecular sieve OX480.
Synthesis of oxygen molecular sieve precursor solution
The precursor solution dissolves raw materials like sodium silicate, sodium hydroxide, and sodium sulfate into water. Then, altering the pH of the solution to a particular interval. The solution contains silicate ions, sodium ions, and oxygen ions plasma, and these ions interact in the solution to form a special molecular structure.
Oxygen molecular sieves were synthesized by crystallization.
The precursor solution was crystallized to form an oxygen molecular sieve crystal. This step must be carried out under certain temperature and pressure conditions to encourage crystal formation. The solution must be continuously stirred or rotated during the crystallization process to avoid crystal sedimentation or aggregation.
Filter washing
The crystallized solution was filtered to remove the unsynthesized solution and impurities, and the pure oxygen molecular sieve crystal was obtained. In the filtration process, it is necessary to use appropriate filtration media, such as filter paper, filter cloth, etc., to avoid crystal loss or blockage. After filtration, the cake must be washed to remove impurities such as ions and organic matter.
Drying treatment
The filtered and washed oxygen molecular sieve crystals are dried to remove water and other solvents. The drying method can be natural drying or hot air drying, and the temperature and time need to be adjusted according to the specific situation to avoid crystal cracking or deformation due to drying.
Activation treatment
After drying, the oxygen molecular sieve crystals must also be activated to activate their adsorption and separation properties. The activation method can be heating, pressurizing, or adding catalyst, etc., and the temperature and time need to be adjusted according to the specific situation to make the crystal have the best adsorption and separation performance.
Screening and packaging
Finally, the activated oxygen molecular sieve crystals were sieved, and the crystals meeting the requirements of a certain size and shape were screened and then packaged. Packaging is usually packed in sealed containers or bags to ensure product quality and safe transportation.
