Silica Gel - An Introduction
We all are familiar with Silica
Gel in our day-to-day lives. They can mostly be seen in the packets containing
our various purchases like electronic goods, leather items and food products.
The main reason behind placing Silica Gel sachets along side packed products is
to ensure that all the moisture present in the closed spaces will not damage
the goods inside.
Silica Gel is usually available in
beads, balls and granular format. The biggest plus point of using Silica Gel is
that it acts as a desiccant and controls the humidity levels in the atmosphere.
The Silica Gel desiccant can be
classified into the following categories- Type A, Type B, and Type C. All these
types are translucent and have multiple pores for better absorption. The three
types have a wide range of uses like liquid adsorbents , catalyst carrier and
drier among others.
The main use of Silica Gel, as
mentioned above, is for effective removal of humidity from packages. For this
purpose, Silica Gel is often graded into different colors, depending on its
use. The most commonly used types are Silica Gel Blue, Silica Gel Orange,
Silica Gel White, and Silica Gel Green. The colour change in these Indicating
Silica Gel is due to the presence of materials like cobalt chloride, which act
as the moisture indicators.
All these types of Silica Gel
desiccant change color as they absorb moisture. This color change is a good
indicator of how much moisture has been absorbed. It will also indicate when
the Silica Gel desiccant is completely saturated and thus needs to be replaced.
Placing a indicating Silica Gel (as they are known in the market) in packaging
applications ensures that the moisture levels inside are maintained at optimum
levels. The main advantage, if one is to opt for Indicating Silica Gels is that
you will get to know instantly whether the Silica Gel is functioning properly
or not. If one is using non-Indicating Silica Gel then it may be a long time
before you get to know that the Silica Gel sachet has got saturated.
For the use of Silica Gel sachets
to be proper, it is important to wok with reliable Silica Gel traders.
