Silica Gel Dubai
Do you know what is the difference between sodium silicate, silica gel, and silicone compounds used in implants? Sodium silicate is a polymeric compound of silicon and oxygen. But it has some of the SiO- groups paired with the Na+ counterion. For the chemical processes, knowing about the components is important.
It absorbs water, changing the crystalline packing of the polymer. It is an excellent desiccant because it can absorb up to 9 molecules of water for every molecule of sodium silicate. In contrast, cobalt chloride can absorb 6 molecules of water per, and calcium sulfate (Drierite) can absorb about 1.5 molecules of water per.
Silica gel is made by acidifying sodium silicate and is essentially silicon dioxide. It is capable of absorbing 4 molecules of water to form silicic acid. It can be heated to regenerate its ability to absorb water. by using a normal oven also, we can reheat a small quantity of silica gel.
But for industrial purposes, regenerating silica gel by using an oven is not possible. Dumbing of silica gel is easy while comparing to other chemicals. However, as per the responsibility towards the public, it is not good to dispose of along with the common waste. That is why industries are finding a way to dump it always.
As we know silica gel is a good desiccant. Silicone or silicone gel is methylated silicon dioxide polymer, dimethylsiloxane, which has a number of polymerized lengths for different applications. The LD50 for dimethylsiloxane polymers is >~ 20g/kg, so over ten times (or more) less poisonous than sodium silicate, and not alkaline, so no risk of burns.
Silicones are available in different forms, though, with varying levels of irritation or hazard. All the desiccants have the ability to absorb moisture from the surroundings. Therefore it has a lot of industrial uses as well as personal uses in our daily life.
