Molecular sieves are a class of materials with uniform pore size and capable of molecular sieving. They are widely used in many fields such as chemical industry and medicine. In the battery industry, especially in advanced energy storage fields such as lithium batteries and fuel cells, molecular sieves also play an important role.

Molecular sieve desiccant has a wide range of applications in the automotive industry, mainly reflected in the following aspects

Molecular sieves are widely used in various industrial fields due to their unique pore structure and excellent adsorption capacity. The following are the main application areas and detailed explanations of molecular sieves in industry

Molecular sieves have important applications in the pressure swing adsorption industry, mainly for gas separation and purification. PSA technology relies on the different adsorption characteristics of different gases on the adsorbent to selectively separate specific gases by changing the pressure. Molecular sieve is one of the commonly used adsorbents, and its unique pore structure enables it to effectively adsorb and separate specific molecules.

The bubbles in polyurethane sealant during use may be caused by multiple factors. The following are some common reasons and information about the defoaming method of molecular sieve activation powder: 1. Reasons for bubbles in polyurethane sealant - Moisture in raw materials: Polyurethane sealant is very sensitive to moisture. Trace moisture in raw materials may cause the sealant to produce carbon dioxide gas during the curing process, thereby forming bubbles. - Uneven stirring: During production and use, if the stirring is uneven, air may be introduced into the sealant, forming bubbles. - Excessive humidity in the environment: When using polyurethane sealant in a high humidity environment, the moisture in the environment will react with the sealant, resulting in the generation of bubbles. - Uneven curing speed: If the curing speed of the sealant is uneven, it may cause the internal gas to fail to escape in time, thereby forming bubbles. 2. Defoaming method of molecular sieve activation powder Molecular sieve is a material with a highly porous structure that can absorb moisture and other small molecules. Therefore, molecular sieve activation powder is often used to absorb moisture in polyurethane sealant and reduce the formation of bubbles. - Usage: Add molecular sieve activation powder to polyurethane sealant, usually before the sealant is mixed. The hygroscopic capacity of molecular sieves can reduce the moisture in the raw materials, thereby reducing the risk of bubbles. - Choose the right type of molecular sieve: Different types of molecular sieves have different pore sizes and adsorption characteristics. For polyurethane sealants, 3A or 4A molecular sieves are generally used, which can effectively absorb moisture without negatively affecting the chemical properties of the sealant. - Control of the amount of added: The amount of molecular sieve added should be optimized according to the sealant formula. Too much molecular sieve may affect the fluidi

Molecular sieves are materials with regular microporous structures, which are often used to adsorb and separate specific molecules in a mixture. The use of molecular sieves to remove water and oxygen from a mixture is mainly achieved through a physical adsorption process, and the specific steps are as follows
