Silica Gel Desiccant
- Silica gel desiccant is a highly active adsorption material.It is usually made of reacting with sodium silicate an sulfuric 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 adsorbs 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.
Chemical Character
How can silica gel work when it's inside a sachet ?
The materials used to make silica gel sachets are specifically chosen to be breathable.
Water vapour passes through them to be adsorbed by the silica gel.
Does silica gel comes ready to use ?
Yes. The silica gel does not need to be 'generated' before use.
It is always sold (loose or in sachets) in a dry condition, ready for use.
How long can silica gel be usefully stored ?
The shelf life of silica gel is around 12 months (although practical experience has shown that it can often far exceed this). The crucial factor is to keep it in a sealed environment until it is needed for use - it will, of course, adsorb moisture from any environment.
How much water vapour can silica gel hold ?
Silica gel will adsorb up to 34% of its own weight in moisture.
Is silica gel dangerous ?
Non-indicating (white) silica gel is non-toxic and non-flammable, it is very inert with a very high melting point.It is very much like sand and thus can safely be sent by any means of transport.
Does silica gel get wet as it adsorbs water ?
No it doesn't, it traps water molecules inside its pores yet remains dry and appears physically unchanged.
Silica gel is a desiccant then ?
Yes, it adsorbs water vapour by physical means, not a chemical reaction.
Water vapour is attracted inside the silica gels crystalline structure.
