Zeolite: Molecular formula: MxOy [Alx + 2ySin- (x + 2y) O2n] • mH2O. Properties: A wide range of silicate minerals. It consists of a three-dimensional lattice of silicon-oxygen tetrahedrons and aluminum-oxygen tetrahedrons connected by a common oxygen. The excess negative charge generated by trivalent aluminum replacing tetravalent silicon consists of monovalent or divalent metal cations, usually alkali metals or alkaline earth Balanced by metal cations.
Zeolites are divided into cristobalite Na [AlSi2O6] • H2O and calcium zeolite Ca [Al2Si3O10] • 3H2O due to different components. Its water content is related to the outside temperature and the pressure of water vapor. When heated, the water can escape slowly, but it does not destroy its crystal structure. Generally light color, glass gloss, hardness 3-3.5, specific gravity 2.0-2.4.
Zeolite has the functions of adsorption and ion conversion, and because each zeolite has its specific uniform pore size (0.3 ~ 1nm), it can only pass molecules of corresponding size. Widely used as catalyst or carrier, desiccant, feed additive, soil improver, sewage purification agent, plastic and paper making filler, seawater extraction of potassium, etc. And a large number of used in cement production.
Natural zeolite powder contains high-purity silicate, its composition is the same as 4A zeolite, it has a loose and porous structure, and its whiteness is extremely high. Can be applied to:
1. Used in the washing industry as raw materials for soaps, toilet soaps, transparent soaps, whitening soaps, washing pastes, and washing powders to improve the appearance quality of products, improve the washing effect, and reduce production costs.
2. Used in the plastics industry, can be used in stabilizers, engineering plastics, polymer materials and other products, play a role in assisting thermal stability, adsorption, flame retardant and smoke suppression.
3. Used in the coating industry, used to disperse, fill, etc. used in construction, used to fill, enhance hardness, etc. Used in cement, increase cement stability and increase tensile and compressive strength, and become a good activity of cement Mixed material.
4. Zeolite is used in laying hens to increase egg production rate, egg weight, eggshell thickness, feed utilization and the content of iron, copper, cobalt, manganese and essential amino acids in eggs. Studies have reported that the addition of 3% and 5% zeolite to Hailan brown commercial layer hen diet can significantly increase egg production rate and reduce feed-to-egg ratio.
