Activated Zeolite Powder

JLH-013 are synthetic zeolite of the type X crystal structure, in sodium form having after dehydration an effective pore opening of 10 Angstroms.It can achieve deep dehydration, adsorb trace moisture, avoid the chemical reaction between water and some active ingredients, and can adsorb acid gases such as hydrogen sulfate and carbon dioxide released in the system, improve the physical and chemical properties of products or materials.

JLH-03-B are synthetic zeolite of the type A crystal structure, in kalium form having after dehydration an effective pore opening of 3 Angstroms.It can be used as adsorbent or desiccant directly in polymer systems; it deals with moisture problems without causing undue problems with shelf-life viscosity, avoid the formation of bubbles, and prolong the service life of the material.

Polyurethane Industry
Moisture is one of the primary challenges in the polyurethane industry since the material readily absorbs water from the air and create gaseous carbon with the isocyanate constituent. The Carbon Dioxide gases can create undesirable effects such as air bubbles on polyurethane coating, which significantly decreases the shelf life of the product.

Specification
Molecular sieve powder is well compatible with commonly used polyols, polyethers and isocyanates. They are easily dispersible and especially stabilized to ensure sufficiently long hardening times.In certain paint and coating systems, moisture introduced into the formulation via the raw materials (solvents, pigments, extenders) causes undesirable side effects.In metallic and zinc-rich paints (such as marine paints for tank ships and yachts), water reacts with the very active metallic pigments such as zinc or aluminum, forming hydrogen. This leads to overpressure in the cans, and in extreme cases to leakage.Zn+H2O→Zn(OH)2+H2Al+H2O→Al(OH)3+H2In metallic and zinc-rich paints, the adverse effect can be avoided by the use of JLH-03-B, JLH-04. It adsorbs the moisture rapidly, with the result that the above reactions can be suppressed, thus reducing returns and storage problems.

JLH-04 are synthetic zeolite of the type A crystal structure, in sodium form having after dehydration an effective pore opening of 4 Angstroms.It can also adsorb molecules such as nitrogen and oxygen from the air and used as a water adsorbent in paints formulation, pastes, adhesives, chemical reaction where water is created and has to be eliminated to increase efficiency of a molecular synthesis.

• Specification

  JLH-04 is largely used to remove moisture from polyurethane polymer systems; it deals with moisture problems without causing undue problems with shelf-life viscosity etc. Other types are used as additives for selective adsorption in defined polymer system or coating systems

JLH-05-A are synthetic zeolite of the type A crystal structure, in calcium form having after dehydration an effective pore opening of 5 Angstroms. It can adsorb C3-C4 normal alkanes, chloroethane, bromoethane, butanol, etc. It can be used in the separation of n-isomeric hydrocarbons, and the co-adsorption of water and carbon dioxide
