8*12 Mesh 2.5mm 3A Molecular Sieve Dryer

8*12 Mesh 2.5mm 3A Molecular Sieve Dryer

Product description

1. 3A molecular sieve is an alkali metal aluminosilicate, sometimes it is also called KA molecular sieve or 3A zeolite molecular sieve. Silicon to aluminum ratio: SiO2/Al2O3≈2, CAS (Chemical Substance Registration Number) No. 308080-99-1.

2. Molecular formula: 0.4K2O 0.6Na2O Al2O2 2.OSiO2 4.5H2O

Product Feature

- It is the smallest of all molecular sieves. It only absorbs moisture and cannot absorb any other components in the air.

- It has high mass transfer efficiency and durability which is widely used in our daily life to make sure the quality of the goods.

- It is usually made with the small size which looks like the bean.And iit is light in weight which is easy to carry and move, easy to transport,greatly reducing the cost of transportation.

- Molecular sieves are very useful in cryogenic operations where liquefaction of gases is required and water must be eliminated to avoid freezing.It is mainly used for drying liquid (such as ethanol), air drying in insulating glass, drying of nitrogen-hydrogen mixed gas, drying of refrigerant, and the like.

- With the authoritative certification of ISO9001:2008, it is manufactured with guaranteed quality and excellent performance as well as the high purity which is up to 99.80%.

Regeneration

Removal of water: dry gas such as nitrogen, air, hydrogen, saturated hydrocarbon, etc. can be used to heat to 150-320℃ and pass into the molecular sieve bed under 0.3-0.5kg/m2 pressure for 3-4 hours, and then to the adsorber Pass in dry cold air for about 2-3 hours, isolate the air and cool to room temperature.

Removal of organic matter: the adsorbate can be replaced from the molecular sieve with water vapor, and then heated to (1). The regeneration can also be regenerated by superheated steam or inert gas at 200-350℃. Exposure to gases that produce explosive mixtures).

The degassed substances can be regenerated by the decompression removal method.

Package

Packed in iron drums, (according to the product model) net weight 125kg, 135kg, 140kg, or according to user needs.

Company information

Shanghai Xuefeng Molecular Sieve Co., Ltd. is a professional manufacturer of molecular sieve products, which belongs to Zhengzhou Xueshan Industrial Co., Ltd. Located in Shanghai Xinzhuang Industrial Zone, covering an area of 24 acer, it has nearly 7000 square meters of most standardized workshop, production equipment and testing instruments. At present, there are a series of stereotyped products such as type A (3a, 4a, 5a), X and so on, as many as 25 varieties have been put on the market.

The products are widely used in natural gas, oil refining, petrochemical, steel, light industry, air separation oxygen production and alcohol dehydration and other industrial fields, and have many successful examples in the deep drying, purification and separation of large and medium-sized industrial equipment at home and abroad. Xuefeng not only has many users in China, but also exports its products to developed countries such as Europe and the United States.

Shanghai Xuefeng has a certain scale of production, with three assembly lines with an annual output of more than 3000 tons of molecular sieves, and has passed the ISO9001-2000 standard Lloyd's quality management system certification, and Xueshanguan is a registered trademark of the product. In order to meet the needs of users, another automatic assembly line with an annual output of 6000 tons was installed in 2008.

Shanghai Xuefeng has introduced and digested the production technology of similar foreign products. The raw powder produced by our own Xueshan Industrial Company is added with clay strengthening agent. After kneading, roasting and activation, the appearance is beige or light gray. We can also produce strip and ball products of different specifications according to customer requirements. In accordance with the domestic (industry) standards of molecular sieves and referring to the main technical indicators of similar foreign products, Shanghai Xuefeng Molecular Sieve has formulated the technical standards for molecular sieve enterprises (QB/SF2690-99).The main testing items and indicators are shown in the sample. At the same time, eight types of molecular sieve products have been tested by Shanghai Research Institute of Chemical Industry ( the domestic molecular sieve national standard and industry standard drafting unit ) and other authoritative organizations, and all quality indicators have reached or exceeded relevant domestic and foreign technical standards.
