Zeolite knowledge: uses and zeolite molecular sieves with unique properties

Feature uses zeolite 13x molecular sieves it is widely used in petrochemical, gas, refrigeration, food and other fields. 
The main applications are: 
1, the drying activated alumina and liquids; 
2, the purification of gases and liquids; 
3, separating gas and liquid; 
4, hydrocracking, catalytic cracking and isomerization catalyst; 
5, detergent additives and water softener
Zeolite has unique properties:
1, water, gas and liquid reversible adsorption 2, 3 cation exchange properties, pore zeolite has a very high internal surface area suitable for use as a molecular sieve for this depth drying, selective adsorption and catalysis, molecular sieves and other adsorbents Comparison prominent features: 
1, 2 very high adsorption capacity, selective adsorption and separation of 3, 4 catalytic properties, ion exchange characteristics

XH molecular sieve

Moisture control is the product yield is closely related to food, in the appropriate temperature and zeolite desiccant humidity, food, bacteria and mold will be breeding at an alarming rate, so that food spoilage, resulting in moisture and color changed. Electronic products due to high humidity will cause the metal oxide, adversely. XH molecular sieve  The desiccant is used in order to avoid the occurrence of excess water caused by defective products.
Molecular sieve desiccant features:
① In the ultra-low humidity conditions, will still be able to absorb a lot of water vapor in the environment, activated alumina  to effectively control the ambient humidity;
② The absorbent fast, in a very short period of time to absorb a lot of water vapor.
Medicine and health products, biological reagents, food industry-specific desiccant. Special desiccant characteristics: high hygiene requirements, packaging materials by the U.S. FDA demonstration, product compact and efficient, environmentally delicate, better compatibility and chemical stability.
