Yuanying 4A molecular sieve is nonpoisonous and tasteless, no
irritations to eyes and skin, does not cause allergies. 4A
molecular sieve deposition in the soil after washing will not cause
pollution, furthermore can improve soil, so it is a natural and
environment-friendly product.
4A Molecular Sieve is a kind of synthetic, with micropore cubic
lattice of alkali metal aluminosilicate salt. It also called Sodium
A molecular sieve, its structure is similar to NaCl. Due to its
effective pore diameter is 0.4nm, so it is called 4A molecular
sieve, its space network structure is staggered by silicon-oxygen
tetrahedron (SiO4) and aluminium-oxygen tetrahedron (AlO4). 4A
molecular sieve decides the adsorption order according to the
polarity of different molecules, adsorbs only those with a
molecular diameter of less than 4A. For small polar molecules and
unsaturated molecules, the greater polarity, the higher degree of
unsaturation, the stronger of selective absorption.
4A molecular sieve adsorbs those substances which molecular
diameter is less than 4A, such as water methanol, ethanol, hydrogen
sulfide, sulfur dioxide, carbon dioxide, ethylene, ethane,
propylene, ammonia, doesnt adsorb molecules which diameter are
greater than 4A (include propane), the selective adsorption
performance to water than any other molecules.
4A molecular sieves application
(1) Argon gas making and purifying
(2) Detergent Builder: 4A molecular sieve as a detergent builder
mainly used to exchange of calcium ions in water to soften water,
remove dirt and prevent dirt deposition. 4A molecular
sievesubstitute trisodium phosphate as detergent builder is a
significant role on solving environmental pollution. 4A molecular
sieve also is used for SOAP plasticizer, toothpaste abrasive,
etc.
(3)Sewage Disposal: 4A molecular sieve as a softening agentinstead
of domestic widespreadsulfonated coal, thereby reducing costs. In
sewage 4A molecular sieves can remove ammonia nitrogen, Pb2+, Cu2+,
Zn2+, Cd2+, etc. In addition to ensure water quality qualified, but
also can recycle heavy metal.
(4) Metallurgical Industry separating agent:separation, extraction
of potassium, rubidium and cesium in brine. In the industry it is
used for collection, separation and extraction of metals and other
processes.
(5) Petrochemical industry as catalyst, drying agent, adsorbent:
depth drying gas and liquid such as air, Â natural gas, LPG,
inert gas, hydrocarbons, saturated hydrocarbons, refrigerant;
dehydrating agent for paint, polyester, dyesand coatings.
(6) For agricultural soil conditioner.
(7) Medicine forsilver zeolite antibacterial agent
(8) Static desiccant for household refrigerating systems,
pharmaceutical packaging, automotive air conditioning, electronic
components, easy to wet and deteriorate material, perishable
chemicals.
(9) Used in the R**2 and R**2 system, molecules adsorbed by 3A
molecular sieve can all be adsorbed by 4A molecular sieve.
