Production technology and main indexes of zeolite

    Zeolite processing technology: the use of existing aluminosilicate ore or coal gangue and other raw materials, after crushing, molding (granulation or extrusion), high temperature sintering, with sodium hydroxide, potassium hydroxide or calcium chloride and other inorganic Aqueous solution in a certain temperature soak for a certain time, and then washing, pressure filtration, crushing, molding, health, drying, activation process from processing.
    The quality of zeolite is good or bad, the most intuitive way to judge is to determine the main indicators, the following we will explain the main indicators of zeolite and the relationship between quality.
    Particle size (mm,%): The appearance of zeolite, particle size range control: the upper and lower limits between more than 95%; upper and lower limits and upper limit plus the limit are not more than 5%.
    Static water adsorption (mg / g): the main indicators of zeolite, the amount of static water adsorption, basically reflects the quality of the zeolite. The range of static water adsorption is generally between 200-265 mg / g.
    Adsorption of specific medium (mg / g): the main indicators of zeolite, different zeolites should be based on its main purpose and its standard pore size, by a specific medium to detect the results of the test will be intuitive to show that the quality of the zeolite The pros and cons.
    Compressive strength (N / stars): the main indicators of zeolite, the use of zeolite conditions are mostly large pressure difference (especially when the adsorption and regeneration switch), if the compressive strength of zeolite does not meet the requirements, The damage to the zeolite, in addition to the useful life of the zeolite, may cause serious damage to the equipment piping. The compressive strength is inversely proportional to the adsorption capacity. How to improve the compressive strength on the basis of ensuring the adsorption capacity is also the key to improve the quality of zeolite.
    Bulk density (g / ml): The main index of zeolite, bulk density and compressive strength is basically proportional relationship, in the case of the same capacity, the greater the bulk density of the better.
    Wear rate (%): the appearance of zeolite, the lower the wear rate, the less the dust of the zeolite, the less the bad situation in use, the quality of the zeolite.

    Packaging water content (%): the smaller the moisture content of the package, indicating that the zeolite in the storage and transportation process of the less pre-adsorption, the user is concerned, in addition to save unnecessary regeneration, it is more valuable. Henan Mingze Environmental Protection Technology Co., Ltd. zeolite packaging using vacuum packaging, to minimize the packaging of water content.
