Insulating glass molecular sieve is a crystalline aluminum silicate mineral spherical particle with a pore size of 3A, which is mainly used for drying the air in the double-layer glass interlayer. Insulating glass molecular sieve can simultaneously absorb moisture and residual organic matter in insulating glass, so that insulating glass can remain smooth and transparent even at very low temperatures. At the same time, it can fully reduce the strong internal and external pressure difference that insulating glass is subjected to due to the huge changes in seasons and day and night temperature differences. Insulating glass molecular sieve also solves the problem of distortion and breakage caused by the expansion or contraction of insulating glass, and prolongs the service life of insulating glass.

Purity and Quality of the Sieves: The effectiveness of molecular sieves in adsorption processes depends heavily on their quality and purity. Customers are concerned with the consistency in quality, the uniformity of bead or pellet size, and the absence of impurities.

Performance Specifications: Customers need to ensure that the molecular sieves meet specific performance criteria, such as adsorption capacity, regeneration capabilities, and the ability to handle specific gas or liquid streams.

Molecular sieves are typically made from materials like zeolites, which are crystalline aluminosilicates. The most common types of molecular sieves are categorized by their pore sizes, measured in angstroms (Å), such as 3A, 4A, 5A, and 13X. Each type is used for different applications depending on the size of the molecules that need to be separated.

1: It is easy to buy non-new products. Some inferior factories or traders will provide second-hand goods to customers.

The adsorption capacity and pressure resistance of these products will be relatively poor. The short service life will have a bad impact on the project.

The molecular sieves provided by this supplier are scrapped in a few months and need to be replaced with new ones. The cost of a single purchase is low, but considering the frequency of replacement, it actually increases the budget of the project.

4A molecular sieve is a type A alkali metal salt crystal with a pore size of 4A. Its selective adsorption performance for water is higher than that of any other molecule. It can also adsorb methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, etc. Adsorbs molecules with a diameter larger than 4A. It is widely used for drying gases and liquids, and can also be used for refining and purifying certain gases or liquids, such as the production of argon.

5A molecular sieve is a spherical or strip-shaped calcium A-type adsorbent with a microporous structure, generally called calcium molecular sieve. The pore size is 5A, which can adsorb any molecules with a diameter smaller than 5A. It also has the effects of 3A and 4A molecular sieves and can be used for pressure swing adsorption separation and co-adsorption of water and carbon dioxide. Based on the industrial application characteristics of 5A molecular sieves, our 5A molecular sieves have high adsorption properties and fast adsorption speeds. They are especially suitable for pressure swing adsorption and are the best products in the pressure swing adsorption industry.

13X molecular sieve is a molecular sieve with a sodium X-type crystal structure. It is composed of alkali metal aluminosilicates and has a certain alkalinity. The effective pore size of 13X molecular sieve is 10A, which can adsorb any molecules smaller than 10A. It has high adsorption power for polar molecules such as water, hydrogen sulfide, and carbon dioxide. Used in air dryers, it can adsorb water and carbon dioxide with high precision.

13X APG molecular sieve is a molecular sieve with a nano-X crystal structure. It is composed of aluminosilicate and has a pore size of 10A. It is to meet the special requirements of the cryogenic air separation industry. A special molecular sieve produced to further improve the adsorption capacity of molecular sieves for carbon dioxide and water and avoid the freezing tower phenomenon during air separation.

13X-HP molecular sieve is a new type of X-type molecular sieve specially used for oxygen production. The principle of oxygen production is: through the pressure swing adsorption of air through the compressor, the air is extracted into the 13X-HP molecular sieve. The molecular sieve absorbs nitrogen, carbon dioxide and other waste in the air, and only the remaining oxygen enters the gas collection bottle and is purified under high pressure through the high-pressure valve. , the oxygen generator can output oxygen after raising the concentration to the standard.
