Molecular Screens, 4A likewise have certain demands for its operating environment. As a permeable product, 4A molecular screens are widely used in several areas due to their microporous molecular screens as adsorption splitting up materials, ion exchange products as well as catalytic products.
Due to the fact that the efficient pore size of 4A molecular sieve is 0.4 nm, it is called 4A molecular filter, which can adsorb water, methanol, ethanol, carbon dioxide, ethylene, sulfur dioxide, hydrogen sulfide, propylene and other reduced molecular substances.
1. The molecular size of Molecular Sieves, 4A
As a result of its efficient pore size of 0.4 mm, it can not adsorb any particle (consisting of gas) with a diameter larger than 0.4 mm, but its careful adsorption performance for water is greater than various other molecules, and it is one of one of the most commonly made use of molecular sieve selections in industry.
2. Molecular Filters, 4A operating setting
1. When the temperature level is 110 ° C, it is possible to vaporize water in a huge room, but it will certainly not eliminate the water in the pores of the molecular filter. As a result, busy, it can be turned on and also dried out by drying in a muffle furnace at a temperature level of 350 ° C and also drying at regular stress for 8 hrs (if there is an air pump, it can be dried out at 150 ° C for 5 hrs).
2. The turned on Molecular Sieves, 4A needs to be cooled down to about 200 ° C in the air (concerning 2 minutes), and need to be saved in a desiccator right away.
3. In an allowable atmosphere, completely dry nitrogen security need to be utilized throughout air conditioning and also storage, which can properly prevent the moisture in the air from being adsorbed once more. Due to the fact that the made use of old molecular sieve has contaminants, not only the temperature level as high as 450 ° C is needed for activation, but likewise water vapor or inert gas (nitrogen, and so on) must be presented to change other materials in the molecular sieve.
4. Prevent oil as well as fluid water when utilizing, as well as try to avoid direct contact with oil and liquid water.
Molecular Sieves, 4A is an alkali steel aluminosilicate, so it is preferred by many customers in the drying of gas and also liquid, as well as it can additionally be used in the refining and filtration of gas or liquid, such as the extraction of argon.
