Molecular sieve Introduction

Molecular sieve is a cubic lattice aluminosilicate compound having. Molecular sieve has a uniform porous structure, the diameter of its pores of uniform size, these cavities can adsorb molecules smaller diameter than the bore to the interior, and the polarity molecular sieve separation of the molecules and the preferential adsorption of the unsaturated molecules having a capacity, which can very different degree, a different degree of saturation, and the boiling point of different molecular size to separate different molecules, which has the effect of "screening" of molecules, so called molecular sieves 13x molecular sieves. Since the molecular sieves have a high adsorption capacity, high thermal stability, etc. The other adsorbents that are not so widely used to obtain the molecular sieve.

oxygen therapy and oxygen care has an irreplaceable role and broad prospects for development

Appropriate oxygen, there microcirculation status, reducing the load of the respiratory system in order to maintain a certain oxygen partial pressure of alveolar gas necessary to reduce the amount 3a zeolite molecular sieves  of load in order to maintain cardiac arterial partial pressure of oxygen required for a certain effect. Thus in clinical medicine, preventive medicine, first aid medicine, geriatrics, activated zeolite powder rehabilitation and health care and medicine,zeolite desiccant oxygen therapy and oxygen care has an irreplaceable role and broad prospects for development.

the oxygen demand for small-scale, but also the use of PSA oxygen, including PSA and VPSA oxygen molecular sieve adsorbent oxygen process, working principle is the use of highly efficient nitrogen-oxygen separation adsorbent nitrogen adsorption certain time desorption regeneration, cyclical operation, the purpose of the two towers or more adsorption towers in parallel, to achieve continuous production of oxygen.

China's aluminum industry is developing very rapidly

China's aluminum industry is developing very rapidly, the demand for aluminum 

is growing. According to official forecasts, 2O00, China's aluminum production will reach 1.8 million tons. regeneration of molecular sieves This requires to develop alumina industry. Since 1954, Shandong Aluminum production, there Zhengzhou Aluminum Plant, Guizhou Aluminum Plant, Shanxi Aluminum Plant put into operation. Alumina production capacity of 1.2 million tons or more. In order to meet the needs of the development of the aluminum industry are planning to build a peaceful grace molecular sieves fruit Zhongzhou Aluminum smelter; and expansion of old plants need to gradually form an alumina base in Central China, Northwest, Southwest aluminum base for a more reasonable layout. Alumina production and species will continue to increase. According to the characteristics and production status of bauxite resources, the total recovery of alumina and alkali zeochem molecular sieves  consumption compared with similar foreign factories, reached the advanced level. And most economical way to recover from the mother liquor circulation gallium; successful use of the alumina production waste - red mud production of cement, from the surface to improve the overall efficiency of alumina production.

A desiccant to absorb moisture from the atmosphere

A desiccant to absorb moisture from the atmosphere, in addition to a liquid, its drying principle is physically adsorbed water molecules in the structure itself, or the absorption of water molecules through chemical means, and changes its chemical structure, into another natural gas separation substances. Common desiccants are lime desiccant chemisorption, magnesium chloride, calcium chloride, phosphorous pentoxide, or soda lime, silicic acid, which are chemically absorb water molecules natural gas dehydration and change its chemical structure into another material.

Moisture control is the product yield is closely related to food, in the appropriate temperature and humidity, food, bacteria and mold will be breeding at an alarming rate, molecular sieve natural gas dehydration  so that food spoilage, resulting in moisture and color changed. Electronic products due to high humidity will cause the metal oxide, adversely. The desiccant is used in order to avoid the occurrence of excess water caused by defective products.

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.

zeochem molecular sieves

Molecular sieve desiccant, which is a synthetic and water molecules have a strong adsorptive desiccant products, crystalline aluminosilicate compound,which has a regular crystal structure and uniform pore pore size of themolecular order of magnitude, it only allows a diameter smaller than the pore molecules into, and therefore a mixture of molecules can be screened by size, so called molecular sieves. Which pore size can be controlled by different process, in addition to adsorb moisture, it can adsorb other gases. At temperatures above 230 ℃, zeochem molecular sieves  the water molecules can still accommodate good. zeolit desiccant 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.

Desiccant applied to prevent the equipment, instruments, electrical equipment, pharmaceuticals, food, textiles and other various packaging items damp, at sea en route desiccant is also widely used, because the goods during transport often large and moisture deterioration due to zeolite 13x temperature, dry agents can effectively dehumidification moisture, so that the quality of the goods are protected.
