What is FNG water-proof silica gel

FNG water-proof silica gel is not produced yet at home and its characteristics are not broken when exposed to water, higher adsorption capacity at low relative humidity, close to the level of narrow pore spherical gel, higher level than active alumina gel,Type A molecular sieve, lower price, various particle sizes can be determined according to customer’s request. The use of FNG water-proof silica gel: 1. air separation, used as adsorbent for the CO2 from liquid air and liquid oxygen and for the acetylene. 2. Desiccant for various gases in modern plants. 3. used as catalyst carrier and ion adsorbent. 4. It is especially suitable for being desiccant in desiccator for the brake in automobile and train. 5. It can replace the functions of various silica gel, Type A molecular sieve, active oxidization in some places. Silica Gel Desiccant Silica gel desiccant is a highly active adsorption material.It is usually made of reacting with sodium silicate ansulfuric acid, aging as well as acid bubble. It is insoluble in water and any solvents.Non-poisonous and tasteless, chemical stability. It won't react with any material except alkli and hydrofluoric acid. Standard white silica gel is referred to as being non-indicating. As absorbs moisture it remains physically unchanged.Non-indicating silica gel is both cheap and effective, available loose in bulk packs or packed in sachets. Silica Gel Feature 1. It will adsorb up to 34%of its own weight in water vapour. This adsorption efficiency is approximately 30 greater than typical desiccant clays, making silica gel the preferred choice where weight or efficiency are important factors. 2. It has an almost indefinite shelf life if stored in airtight conditions. 3. It can be regenerated and reused if required. Gently heating silica gel will drive off the adsorbed moisture and leave it ready for reuse. 4. It is a very inert material, it will not normally attack or corrode other materials and with the exception of strong alkalis and hydrofluoric acid is itself resistant to attack. 5. It is non-flammable. 6. It is most frequently and conveniently used packed in a breathable sachet or bag. These are available in a wide range of sizes suitable for use with a wide range of applications.
