Silica Gel Desiccant for Moisture Drying

Silica gel is said to be the best desiccant when it comes at absorbing moisture. Removing moisture from unnecessary places is very necessary as even a drop of it can become a reason for big loss. Silica gel is also of two types indicating and non-indicating. White silica gel comes under the category of non-indicating category where blue and orange are the indicating ones. 

Silica gel desiccant is used in various industries to keep the products environment dry and moisture free pharmaceuticals, food, electronics, textile, stationery, agriculture, leather, air, gas and many more. Apart from controlling moisture it is also used for the removal of air, gas and water. Once the product starts to react with moisture, (specially the consumable goods) it starts to lose its originality and effectiveness. By protecting it against moisture it is possible to avoid spoilage and growth of fungi, mold, bacteria and other micro-organisms which inhibits in moisture condition. So, using silica gel can increase the shelf life of the products and keep them fresh for a long term.

Silica Gel Orange Indicating Serves Various Uses

Packaged food is the most common type of food that we consume today. Due to the fast paced lifestyle that we follow, storing food has become the only option for us. Storing food can be difficult as there are many problems involved in storing eatables. One of the main problems is spoiling of the food articles due to moisture. The presence of moisture will promote the growth of fungus mold, mildew and bacteria on food items. In order to prevent this, some particular desiccants are used to suck up the moisture and create a dry atmosphere inside the packages. There are many types of desiccants available in the market, but one of the safest and commonly used desiccants is silica gel.

Silica gel is a hygroscopic and can absorb moisture up to 40% of its weight. It is an USFDA approved, non-toxic, DMF Free, organic desiccant. Silica gel is hard, irregular and in the shape of granules or beads. It has a high ability to desiccate. As it exhibits a lower vapor pressure than the surrounding air, water molecules adhere to the gels surface. Standard white silica gel is non-indicating as remains physically unchanged even when it adsorbs moisture. Non-indicating silica gel is cheap and effective, available in bulk packs sachets. Size of Beads is 2-5mm, 3-5mm and 4-8mm.

Silica Gel and Its Application as Silica Gel Orange, Breathers and Granular Explored!

Silica gel is basically a composition of silicon dioxide in amorphous form. So, it produces small and hard irregular beads or granular which look like crystals. It helps in absorbing moisture or odor. The absorption is possible because of the micro pores present in its structure. It not only absorbs the moisture but its interlocking feature locks them inside which results in change of shape and color of the granular. Moisture is easily absorbed in the granular because it possesses lower vacuum pressure than the surrounding air. Absorption stops when the level of pressure inside the granular as well as outside is equal. Silica gel is available in two types, one is indicating and the other is non-indicating. Under the indicating category comes orange and blue silica gel and white is the non-indicating type. By indicating silica gel it means that the granular changes its color after they fully saturates.

Silica Gel and Activated Carbon used in desiccant Canisters!

The best thing to use silica as desiccant is that it can be reused even after it is fully contaminated by heating it over certain temperature. One drawback that these desiccants have is that it cannot be used loosely. Usually it is used by packing them in small packets. But what about huge containers? In that situation huge silica gel Canisters are used.

Whenever you are making for desiccants always choose those which have successfully undergone the FDA standards. This makes it safe that they can be used in close contact with drugs or food items. But still in any case a basic layer is required. In the canisters you have the advantage to use a single desiccant individually or you also have the option to use it in combination with some other desiccant. Like silica gel and activated carbon can be used in combination where silica gel is best in absorbing moisture and activated carbon is used to absorb odor. These canisters are available in various sizes. Advantage of using these canisters is that it can be customized according to the requirement. It is absolutely safe to use desiccant canisters as it has welded ends which provide more structural strength. And those welded ends have the capacity to stay sealed even in extreme pressure.

Overview on Moisture Absorbing Silica Gel for Breathers

Among all the moisture absorbing techniques, Silica gel is said to be the most efficient and the best way to absorb the unwanted humidity. Humidity is the biggest enemy against the quality of a good product. So in order to retain the quality the best way, silica gel beads should be used. They are available in 3 variants - White, blue and orange. Among the three, Silica gel blue bead and orange bead are the indicating type silica gel. Industrial people mostly use the blue one. It is used in various industries like food and packaging, Pharmaceutical, lather and also in gas industry. This blue bead will initially turn to pink when it is fully absorbed with moisture. Another reason for them being used in such huge quantity is that they are absolutely non-toxic and environmental friendly.

Now-a-days, this gel is also being used in the transformer breathers. Usually when Blue silica gel for breather is used, it provides an efficient and an effective way to control the level of moisture content in the electric equipment. As when the equipment changes its temperature from cool to hot or vice versa it creates a huge amount of humidity in the environment. This needs heavy breathers to clean the nearby environment and to continue the working of the equipment. There are many companies across the world which supplies Silica gel transformers up to the capacity of 2000Kva.

Silica gel for breathers is basically transparent hollow cylinders which have tubes and it contains silicon salt which is also called as silica gel. It consists of cobalt which works as indicator. The body and the oil cup of the breathers are made up of transparent and unbreakable polycarbonate plastic and is also UV protected. Many of the breathers also have gel removing plus refining method which aims to reduce the labor and also avoids air leakage. Breathing actually happens within the transformers which is the act of contraction and expansion of the oil masses within it.

Usefulness of Silica Gel Blue and Silica Blue Orange

We always wonder about the usefulness of silica gel packets that come along with the packaging of the things that we buy. These little packaging of these gels are very helpful and is responsible for the successful packaging of the commodities. With the advancement of the technology in the development of silica gel, self-indicating silica gels are now becoming increasingly popular. They are basically of two types, silica gel blue and silica gel orange. These gels are mainly responsible for the absorption of moisture and are kept in small packets. These are granular substances that are made from a chemical substance called silicon silicate. These are made basically by synthetic processes. The end result is translucent, hard granules.

These are basically silica gel that is amorphous and is made into irregular granules that look like beads. These silica gel beads have micro-porous structure that has interlocking cavity that results in high surface area. These self-indicating gels are basically the same as normal indicators but with only the exception that in these gels, chemical or organic components are added that are sensitive to moisture. These chemicals react differently to the different levels of moisture. Their reaction is shown by their color change.  Low vapor density is responsible for the fact that water is able to stay on the surface of the beads. The process of adsorption by these beads gets stopped when the state of equilibrium is attained. This state is basically attained when the vapor pressure of the surface and the surroundings gets equal.

These are used in the industries where excess moisture can cause damage to the goods. The most basic use is for the drying and cleaning of the air and gases. These beads find great use in any kind of a dehumidification process. Silica beads are also used in the drying of analytical sample as they don’t participate in any type of a chemical reaction. They are also used to protect the sensitive optical instruments and lenses from damage caused due to humidity.
