What is 4A Molecular Sieve?

The pore size of 4A molecular filter is 4A. It adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, and propylene. It does not adsorb any type of particles with a diameter larger than 4A (consisting of lp). Its selective adsorption performance for water is greater than any other particles. It is among one of the most commonly used molecular screens in industry.

4A Molecular Sieve Property

Application of 4A Molecular Sieve

1. Daily chemicals – detergent accessories
The major result of 4A molecular sieve as a cleaning agent additive is to soften the water with calcium ions in the exchange water, remove dirt as well as stop dirt from re-accumulating. 4A molecular sieve is currently one of the most commonly made use of and also most fully grown product amongst phosphorus-substitute cleaning agent builders. 4A molecular filter replaces sodium tripolyphosphate as a cleansing help and has a significant result on dealing with environmental pollution. 4A molecular filter can likewise be made use of as a forming agent for soap and a conflict representative for tooth paste.
2. Environmental management– sewage therapy
4A molecular screen can get rid of NH3-N, Pb2+, Cu2+, Zn2+, Cd2+, etc in sewage. The sewage discharged from market, farming, civil usage and marine animal husbandry consists of ammonia nitrogen, which not only damages the source of income of fish and also contaminates the breeding setting, yet also advertises the growth of algae, creating the clog of rivers as well as lakes. Because of its high selectivity for NH4+, 4A molecular screen has actually been efficiently utilized in this field. Wastewater discharged from metal mines, smelters, steel surface treatment and also chemical industries has heavy metal ions that are very hazardous to the body. Utilizing 4A molecular filters to treat this wastewater can not only guarantee water high quality and separation, yet likewise recuperate heavy metals. 4a molecular filter is reasonably priced as well as ideal for large purchases.
3. Various other usages
( 1) Water treatment – difficult water softener, which can change the sulfonated coal currently extensively utilized in my country, therefore reducing costs; (2) Metallurgical sector – dividing representative, separates as well as removes potassium, rubidium, and Cesium etc. Used in industry to enhance, different and also extract steels and other procedures; (3) Petrochemical market – catalysts, desiccants, adsorbents; (4) Farming – soil conditioners; (5) Medication — Silver crammed zeolite antibacterial representative.

How to Use 4A Molecular Sieve

Because the efficient pore dimension of 4A molecular sieve is 0.4 nm, it is called 4A molecular screen It can adsorb water, methanol, ethanol, carbon dioxide, ethylene, sulfur dioxide, hydrogen sulfide, propylene and also various other low molecular substances.

1. Molecular dimension of 4A molecular filter

Due to the fact that its effective pore dimension is 0.4 mm, it can not adsorb any kind of molecules with a size above 0.4 mm (consisting of lp), however its discerning adsorption efficiency for water is greater than various other particles. It is just one of one of the most commonly used molecular filter selections in industry.

2. Operating environment of 4A molecular filter.

1. When the temperature level is 110 ° C, it is feasible to evaporate water in a large space, however it will certainly not eliminate the water in the pores of the molecular sieve. Consequently, in the laboratory, turned on dehydration can be accomplished by drying with a muffle furnace at a temperature level of 350 ° C and drying out under regular pressure for 8 hrs (if there is an air pump, it can be dried out at 150 ° C for 5 hours with air extraction).

2. The activated 4A molecular screen is cooled down to around 200 ° C airborne (concerning 2 mins) and also requires to be saved in a desiccator promptly.

3. In permitted environments, completely dry nitrogen defense must be utilized throughout cooling and storage to successfully prevent water vapor airborne from being adsorbed once more. Because old molecular screens consist of contaminants after usage, not just the temperature level should be as high as 450 ° C throughout activation, yet water vapor or inert gas (nitrogen, etc) should also be presented to replace other substances in the molecular filters.

4. Stay clear of oil and also fluid water when utilizing it, as well as try to prevent direct contact with oil as well as liquid water.

As an alkali steel aluminosilicate, 4A molecular screen is preferred by many clients for the drying out of gases as well as liquids. It can additionally be made use of for the refining as well as purification of gases or fluids, such as the extraction of argon gas.
