In 1998 the European Union decided that cobalt chloride possess health risk and is dangerous to the environment. So they prohibited the use of Silica Gel Blue or Blue Silica Gel as it contains Cobalt chloride in it. And hence the product vanished from the American and European market. But most of the industries need Indicator substances, so Silica Gel orange is developed to cover this need. It is also known as Enviro gel. The main ingredient in indicating silica gel orange is silicon dioxide, it uses organic substance instead cobalt chloride for the purpose of indicating the humidity. It Continue Reading->
Silica Gel Packets:
A desiccant is a substance, which is capable of adsorbing/absorbing moisture from its surroundings. This helps in keeping the vicinity dry and this feature is found to be useful in many industries like petroleum and natural gas, pharmaceuticals, food processing and storage and transportation among others. The most commonly used types of desiccant are Silica Gel, Activated Alumina and Molecular Sieves.
Silica Gel is a part of our everyday life. We all have seen Silica Gel sachets in any new purchase we make. Silica Gel sachets are placed in packages to absorb any moisture present so that it does not spoil the product packed inside. Silica Gel becomes very important in the case of food products which can become stale if they come in contact with moisture. The main highlight of Silica Gel is its even-sized pores, which make it a high capacity moisture absorber.
Types of Silica Gel:
In the market, Silica Gel is available in many forms. These include 1) the indicating ones (where the color changes from blue/orange to white) and the 2) non-indicating types, which are colorless. Both the types of Silica Gel, like Silica Gel blue and Silica Gel white, find various uses in different sectors. The various industries, which make use of Silica Gel packets include Pharma, food products, aerospace, computers, automobile parts, military equipment and rolled steel among others.
Silica Gel in the Automobile Industry:
Like all other industries, Silica Gel also has important uses in the automobile industry. Silica Gel Packets, which we get with new purchases, should not be thrown away as they have many uses. In automobiles, Silica Gel packets are mainly utilized to keep the engines dry during harsh weather conditions like winter.
The manner in which this can be done is explained as follows- One must first place the Silica Gel in old plastic canisters. Holes smaller than the Silica Gel beads are then drilled into the canisters to prevent the beads from coming out. In the next step, the canisters are placed inside the carburettor to safeguard the engine against moisture. This precaution is usually undertaken when the automobile is parked during the winter season. The use of Silica Gel sachets also prevents the bearings and internal parts of the automobile engine from rusting.
Another major use of Silica Gel beads in cars is a ready-made air freshener. If one has silica gel sachets at home, it is very easy to make your very own air freshener. First soak silica gel beads in essential oils to make a freshener. Then keep sachets of these scented silica gels in your car to secure a lovely soothing smell. The Silica Gel freshener can be used many times as the Silica Gel beads can be regenerated by simple heating.
