Molecular Sieve Activated Powder Properties
What is Molecular Sieve Activated Powder ?
Molecular sieve-activated powder is the original powder of molecular sieve after roasting activated at a high temperature to remove the water in the channel, with excellent dispersion and strong adsorption activity. 
Trace water is an important issue in producing and preparing Polyurethane (PU) products. Trace water in polyols reacts with isocyanate to form carbon dioxide, resulting in foaming. At the same time, a large amount of heat is released, resulting in a shorter service life (operation time). JLH series molecular sieve activated powder added to polyurethane and other product systems can be effective selective adsorption of trace water in typical polyurethane formula, inhibit the occurrence of side reactions, reduce the bubble generation, and extend the purpose of the application period. Jlh-03-b and JLU-PU are especially suitable for polyurethane systems. 
RHCO+H2O--RNH2+CO2 
In addition, in some special paint or coating systems, raw materials, solvents, pigments, additives, etc.) trace moisture can cause adverse effects, such as in zinc metal or coating, the existence of trace moisture will react with the lively metallic pigment of zinc, aluminum and other generate hydrogen gas, will cause the tank pressure is too high, even in extreme circumstances cause leakage. 
JLH series molecular sieve-activated powder has excellent chemical stability; molecular sieve-activated powder itself will not react with the use of the system.  

Crystal structure: molecular sieve active powder has a crystal structure. Its crystal is mainly composed of silicon, aluminum, oxygen, and other elements, and the structure is highly ordered. Their channels and port sizes can be adjusted during synthesis to suit different application requirements.

Uniform pore size: The pore size and pore size of molecular sieve active powder can be precisely controlled, and the pore size is usually between 1-100 angstroms, which can adsorb and separate molecules of different sizes. Therefore, they have many applications in gas separation, liquid separation, and catalysts.

The molecular sieve active powder has a very high specific surface area, usually more than a few hundred square meters per gram. They are extremely absorbent and active, allowing them to interact with a broad spectrum of ions and molecules.

Acidic function: Some molecular sieve active powders are acidic and can be used in fields such as catalysts and ion exchangers. The surface of these molecular sieves has acidic functional groups, which can interact with basic molecules or ions to achieve adsorption, separation, and catalytic reactions.

Applications of Molecular Sieve Activated Powder:

Gas separation: molecular sieve active powder can be used in gas separation, such as oxygen, nitrogen, hydrogen, carbon dioxide, and other gases separation and purification. Because of its high adsorption capacity and selectivity, it is widely used in industrial gas production and purification. For example, in the petrochemical process, molecular sieves can adsorb and separate molecules of different diameters, thereby obtaining high-purity monomers and improving the quality and purity of petroleum products.
Liquid separation: molecular sieve active powder can be used in liquid separation, such as the separation of water and organic matter, and dehydration in petrochemical processes. Because of its high adsorption capacity and good physical and chemical stability, it is widely used in petroleum, chemical, pharmaceutical, and other fields. For example, the molecular sieve can adsorb and separate organic pollutants in effluent in wastewater treatment, thereby achieving water purification.
Catalyst: molecular sieve active powder can be used as a catalyst in many chemical reactions, such as alkylation reactions, isomerization reactions, disproportionation reactions, etc. It is widely used in industrial catalysts because of its high activity and selectivity. For example, in the petrochemical industry, molecular sieve catalysts can produce high-purity petroleum products such as gasoline.
Ion exchanger: molecular sieve active powder can be used as an ion exchanger for water treatment, nuclear industry, and other fields; because of its high exchange capacity and good physical and chemical stability, it is widely used in ion exchange. For example, in the nuclear industry, molecular sieves can remove radioactive ions from water, reducing the radiation dose.
Biomedical field:  molecular sieve active particles can also be employed in biomedical applications like biosensors, drug carriers, etc. Due to its high adsorption capacity and biocompatibility, it is used extensively for drug delivery and biomedical diagnostics. For example, the molecular sieve can be used as a drug carrier to wrap the drug in the pore and achieve the slow release of the drug, thereby improving the drug's efficacy and reducing side effects.
Environmental protection: molecular sieve powder active powder has many applications for environmental protection. For example, it can be used to remove harmful gases in the air, such as organic pollutants such as formaldehyde and benzene, as well as acidic gases such as nitrogen and sulfur. In addition, molecular sieves can also be used in fields such as soil remediation and sewage treatment to improve environmental quality.
Energy field: molecular sieve active powder is also widely used in the energy field. For example, it can be used in hydrogen production, storage, and fuel cells. A molecular sieve has high adsorption capacity and high stability, which can be used in hydrogen production and storage. In addition, molecular sieves can also be used as catalyst carriers for fuel cells to improve the efficiency and stability of fuel cells.

Production Method of Molecular Sieve Activated Powder:

Preparation of synthetic raw materials: Corresponding raw materials need to be prepared for producing molecular sieve active powder, including inorganic compounds such as sodium silicate, sodium hydroxide, sodium sulfate, sodium chloride, and organic compounds such as phenol and benzyl alcohol. These raw materials must be added to the reactor in proportion and order.

Synthesis reaction: The prepared raw materials are synthesized under certain temperature and pressure conditions. This process requires special catalysts, such as sulfuric acid, sodium hydroxide, etc., to promote the reaction. At the end of the synthesis reaction, the resulting product is a mixture of molecular sieves.

Separation and washing: The resulting molecular sieve mixture must be separated and washed. This process requires filtration equipment to separate the molecular sieve from the reaction mixture and then wash it with an acid-base solution and water to remove impurities and organic matter.

Drying and grinding: The washed molecular sieve must be dried and ground. Drying can be done by drying or sun drying, and grinding is to grind the molecular sieve into a fine powder for subsequent processing.

Product treatment: The milled molecular sieve requires product treatment, including packaging, testing, analysis, and storage. The detection mainly includes physical and chemical properties, such as the adsorption performance of molecular sieves, specific surface area, pore size distribution, and other indicators. An analysis is to analyze and evaluate the structure and performance of molecular sieves to understand their application field and use effect. Storage is essential to maintain the stability and quality of the product. It typically requires to be kept in a cool, dry area to avoid the impact of elements like humidity and oxidation.
