*-) What is 4A Molecular Sieve
4 molecular sieve is a kind of alkali metal silicic acid salt and
can absorb water and other molecules with a critical diameter less
than 4 such as NH3, H2S, SO2, CO2, C2H5OH, C2H6, and C2H4. It is
widely used in the drying, refining and purification of liquids and
gases (such as the preparation of argon).
*-) 4A Molecular Sieve Applications:
2.1.Polyester Agent Additives
These molecular sieves are used to assist detergents as they can
produce demineralized water through calcium ion exchange, remove
and prevent the deposition of dirt. They are widely used to replace
phosphorus. The 4 molecular sieve plays a major role to replace
sodium tripolyphosphate as detergent auxiliary in order to mitigate
the environmental impact of the detergent. It also can be used as a
soap forming agent and in toothpaste.
2.2Harmful Waste Treatment
4 molecular sieves can purify sewage of cationic species such as
ammonium ions, Pb2+, Cu2+, Zn2+ and Cd2+. Due to the high
selectivity for NH4+ they have been successfully applied in the
field to combat eutrophication and other effects in waterways due
to excessive ammonium ions. 4 molecular sieves have also been used
to remove heavy metal ions present in water due to industrial
activities.
2.3.Other Purpose
The metallurgical industry - separating agent, separation,
extraction of brine potassium, rubidium, cesium.
Petrochemical industry, catalyst, desiccant, adsorbent
Agriculture - soil conditioner;
Medicine - load silver zeolite antibacterial agent.
