Application fields of molecular sieves
Release time：2024-09-05
Chemical industry:
Polyurethane field: used in polyurethane products (such as coatings, adhesives, sealants) to avoid foam and extend the service life; The curing time of the two-component polyurethane adhesive can also be adjusted to provide sufficient margin for construction operations.
In the field of paint and coatings: used as an additive or aggregate in coatings, paints, resins, and certain adhesives, it has the effect of reducing moisture, eliminating bubbles, improving material uniformity and strength.
Other chemical production: It can be added as a selective adsorbent to specific polymer or coating production processes to adsorb gases such as CO ₂ and H ₂ S generated during the production process.
Industrial gas field:
Gas drying: used for drying natural gas, methane gas, refrigerants and other gases. For example, 3A molecular sieve activated powder can be used in natural gas deep dehydration devices, which has adsorption ability for strongly polar water molecules, thus achieving the drying effect.
Gas purification: It plays a role in industrial gas purification processes such as argon purification, removing impurities and moisture from gases.
Other fields:
Hollow glass industry: 3A molecular sieve activated powder can be added to the hollow glass composite adhesive strip as an amorphous desiccant to prevent the hollow glass from twisting and breaking due to the strong internal and external pressure difference caused by seasonal and diurnal temperature differences, fully extending the service life of the hollow glass.
Electronics industry: For example, in electronic component sealing and resin filling, 5A activated powder can be used to remove trace amounts of moisture and other impurities, ensuring the performance and reliability of electronic components.
