Compressed Air drying
All the atmospheric air contains a certain amount of water vapor. Now, imagine the atmosphere as a huge, slightly moist sponge. If we squeeze the sponge very hard, the absorbed water drops out. The same happens when the air is compressed, which means the concentration of water increases and these gaseous water condenses into liquid water.To avoid problems with the compressed air system, using the post-cooler and drying equipment is required.
Silica gel, activated alumina or molecular sieve can adsorb water and achieve the purpose of removing water in compressed air.
Joozeo can suggest different adsorption solutions, according to different needs, dew point requirements from-20 ℃ to-80 ℃; also provide customers with adsorption and desorption data of adsorbent under different conditions.

Polyurethane Dehydration
Polyurethane(coatings, sealants, adhesives)
No matter single-component or two-component polyurethane products, water will react with isocyanate, produce amine and carbon dioxide, amine continue to react with isocyanate, so that its consumption to release carbon dioxide gas at the same time, form bubbles on the surface of the paint film, leading to deterioration or even the performance of the paint film failure. Adding the molecular sieve (powder) to the plasticizer or dispersant,2%~5% is sufficient to remove the residual moisture depending on the moisture in the system.
Anti-corrosive coating
In the epoxy zinc-rich primer, a trace amount of water will produce a great reaction with the zinc powder, produce hydrogen, increase the pressure in the barrel, shorten the service life of the primer, resulting in the tightness, wear resistance and hardness of the coating film. Molecular sieve (powder) as a water absorption desiccant, pure physical adsorption, while eliminating water will not react with the substrate, safe and convenient.
Metal powder coating
Similar reactions can occur in metal powder coatings, such as in aluminum powder coatings.
Refrigerant Drying
The life of most refrigeration system depends on whether the refrigerant is leaking. The leakage of refrigerant is due to the combination of refrigerant with the water containing to produce harmful substances corrode the pipeline. The JZ-ZRF molecular sieve can control dew point in low condition, high strength, low abrasion, and can protect the chemical stability of the refrigerant, which is the best choice for refrigerant drying.
In the refrigeration system, the function of the drying filter is to absorb the water in the refrigeration system, to block the impurities in the system to prevent it from passing, to prevent ice blocking and dirty blocking in the refrigeration system pipeline, to ensure the smooth capillary pipe and the normal operation of the refrigeration system.
The JZ-ZRF molecular sieve is used as the inner core of the filter, mainly used to continuously absorb water in the refrigeration or air conditioning system to prevent freezing and corrosion. When the molecular sieve desiccant fails due to too much water absorption, it should be replaced in time.

Pneumatic Brake Drying
In the pneuamtic brake system, the compressed air is a working medium used to maintain a stable operating pressure and is clean enough to ensure the normal operation of each valve piece of the system. The two elements of molecular sieve dryer and air pressure regulator are set in the system, which function to provide clean and dry compressed air for the braking system and to keep the pressure of the system in a normal range (usually at 8~10bar).
In the air brake system of the car, the air compressor output air containing impurities such as water vapor, if not treated, which may be converted into liquid water and combined with other impurities to cause corrosion, even freezing the trachea at extreme temperature, causing the valve lose efficacy.
Automobile air dryer is used to remove water, oil drops and other impurities in the compressed air, it is installed in the air compressor, before the four-loop protection valve, for cooling, filter and dry the compressed air, remove the water vapor, oil, dust and other impurities, to provide dry and clean air for the braking system. Automobile air dryer is a regenerative dryer with a molecular sieve as its desiccant.JZ-404B molecular sieve is a synthetic desiccant product with strong adsorption effect on water molecules. Its main component is a microporous structure of the alkali metal aluminum silicate compound with many uniform and neat holes and holes. Water molecules or other molecules are adsorbed to the inner surface through the hole, with the role of sieving the molecules. The molecular sieve has a large adsorption weight ratio and still holds water molecules well at high temperatures of 230 ℃.
The moisture in the gas circuit system will corrode the pipeline and affect the braking effect, and it can even cause the failure of the braking system. Therefore, attention should be paid to the frequent discharge of water in the system and regular replacement of the molecular sieve dryer, if problems is found,it should be replaced in time.

Desiccant Of Insulating Glass
Insulating glass was invented in 1865. The insulating glass is a building material with good heat insulation, sound insulation, beautiful and practical, and can reduce the dead weight of the building. It is made of high-efficient sound insulation glass of two (or three) glass using high strength and high gas density composite adhesive to bonding glass to an aluminum alloy frame containing desiccant.
Aluminum double-channel seal
Aluminum partition effectively support and evenly separated from the two pieces of glass, aluminum partition is filled with insulating glass molecular sieve (particles) desiccant, to form a sealing space between the glass layers.
Insulating glass molecular sieve can absorb water and residual organic matter in the hollow glass at the same time, making the insulating glass still keep clean and transparent even at a very low temperature, and can fully reduce the strong internal and external pressure difference of the insulating glass due to the huge changes in the temperature difference between season and night. The insulating glass molecular sieve also solves the problem of distortion and crushing caused by the expansion or contraction of the hollow glass, and prolong the service life of the insulating glass.
Application of insulating glass molecular sieve:
1) drying action: to absorb the water from the hollow glass.
2) Anticoagulant Effect.
3) Cleaning: the floating dust (under water) is very low.
4) environmental protection: can be recycled, harmless to the environment, can be recycled and reused.
5) energy saving effect: used for hollow glass, and reasonably cooperate with insulating glass aluminum strip, sealant, to ensure the energy saving effect of hollow glass.
Composite adhesive strip-type seal
insulating sealant strip is a collection of partition and supporting function of aluminum frame, drying function of insulating glass molecular sieve (powder), sealing function of butyl glue, and structural strength function of polysulfur glue, which can be bent to any shape for insulating glass sealant strip can be installed on the glass.

Desiccant Packs
Electronic components:
Semiconductor, circuit boards,various electronic and photoelectric elements have high requirements for storage environment humidity, humidity can easily lead to the quality decline or even damage of these products. Using JZ-DB molecular sieve drying bag / silica gel drying bag to deeply absorb moisture and improve storage safety.
Drugs:
Most drugs, whether tablets, capsules, powder, agents and granules, can easily absorb moisture and decompose or dissolve in a wet environment, such as foaming agent type in water or damp will produce gas, leading to expansion, deformation, rupture and failure. Therefore, drug packaging usually needs to place a deep JZ-DB desiccant (molecular sieve) to ensure the validity of the drug.
