13X molecular sieve adsorbent is a kind of aluminosilicate compound with cubic lattice. It is widely used in aerosol industry. This is closely related to the working principle determined by its unique structure and performance. The following is a detailed introduction.
Drying Aerosol Raw Materials
In aerosol production, many raw materials such as solvents and active ingredients have strict requirements on moisture content to ensure the stability and performance of the product. Xintao 13X molecular sieve has a pore size of about 10 angstroms. Due to the strong electrostatic field on the internal surface of the molecular sieve, it has a strong adsorption force on water molecules and can adsorb water molecules in the raw materials into its micropores, thereby achieving the purpose of drying the raw materials. The static water adsorption can reach 26%. For example, in aerosol propellants, 13X molecular sieves can be deeply dried to remove the moisture in them, preventing moisture from causing adverse reactions such as hydrolysis of aerosols during storage, affecting product quality. For active ingredients or other additives in aerosols, if they contain moisture, they may reduce activity or cause deterioration. 13X molecular sieves can dry these ingredients to ensure their stability in the aerosol system.
Purify Aerosol Gas
In aerosols, the gases used, such as propellants, may contain impurity gases, such as carbon dioxide, sulfides, etc. These impurities will affect the performance and use of aerosols. 13X molecular sieves beads can purify these gases. The pore size of Xintao 13X zeolite enables it to selectively adsorb specific molecules. For example, carbon dioxide molecules and some sulfide molecules can enter its micropores, among which the adsorption value of static carbon dioxide can reach 18.5%. For example, carbon dioxide present in aerosols may affect the pressure stability and use effect of the product. Zeolite 13X can effectively adsorb carbon dioxide to ensure that the pressure of the aerosol is stable during use, and the valve opens and the spray effect is normal. In addition, some aerosol raw materials may contain impurities such as sulfides, which produce odors and may cause harm to equipment and the environment. 13X molecular sieve desiccant can remove sulfides such as hydrogen sulfide and mercaptan, play a role in desulfurization and deodorization, and improve the quality and use experience of aerosols.
As a Catalyst Carrier
Xintao 13X molecular sieve particles have a large specific surface area and rich pore structure. The catalyst particles can be evenly distributed on the micropores and surface of the molecular sieve, and the reactant molecules can more easily contact the catalyst, thereby accelerating the reaction. At the same time, the pore structure of the molecular sieve can also screen the reactant and product molecules, allowing only molecules that meet the pore size to enter and exit, thereby improving the selectivity of the reaction. In the production process of some aerosols, chemical reactions are required to prepare specific components or pre-treat raw materials. 13X molecular sieves desiccant can be used as catalyst carriers to provide a place for catalytic reactions and improve catalytic efficiency.
Product Separation And Purification
Based on the “screening” effect of molecular sieves, when molecules of different sizes and shapes pass through the micropores of 13X molecular sieves, due to the limitation of pore size, only molecules that meet the pore size can enter and be adsorbed, while larger molecules are excluded. In the production process of aerosols, complex mixtures are sometimes required to be separated and purified to obtain high-purity products. 13X molecular sieve adsorbent can be used to separate substances of different molecular sizes and shapes, achieving fine separation and purification of aerosol components.
