Product Description

【Character】Variable-pressure Adsorbent silica gel is transparent or semitransparent glassy in substance, chemical molecular formula is mSiO₂．nH₂O with stable chemical property, no toxin and no special odor, possessing some similar characteristics with fine-pored silica gel, while its selective absorbing performance is better than fine-pored silica gel, possessing fast absorption and dehydration.

【Use】Pressure swing adsorption (PSA) is one kind of high-tech to separate and purify air; mainly used for reclaiming, separating and purifying carbon dioxide in synthetic ammonia industry, food, beverage processing industry, as well as drying, damp proofing and dehydration of organic products, etc.

【Specialness】Variable-Pressure adsorbent silica gel is a special adsorptive material for gas separation by Shandong SINCHEM’s research and development. Third-generation (SIN-03 type) through a special process adsorbent, to control the adsorbent’s pore size distribution and volume, change the physical properties of the surface of the adsorbent, cause to take absorption capacity, adsorption, decarburization quickly, adsorption choice strong factor ,separating high.
