The demand of moisture desiccants is reaching the sky. So far, there is no better way out to prevent products that are vulnerable to moisture and humidity from getting spoiled or damaged. While such kind of damage causes a large amount of loss for the company on the other hand, the reputation of the company is also put at stake. In order to avoid such difficulties, all types of organization especially, those needs to deal with transportation are opting for this strategy to use these desiccants in their packaging. It is frequently observed that different types of products (mainly food Continue Reading->
Silica Gel, an Amorphous Form of Silicon Dioxide having well known application in moisture adsorption in near by ambience. It works on the principle of adsorption i.e. capture moisture in its surface. One of the indicative forms of Silica Gel is Blue silica Gel impregnated with cobalt chloride for visual alert and alarm for replacement.
Indicating Blue Silica Gel changes its color changes to light Pink from Dark Blue, slowly and gradually when reaches to Saturation level. This color indicative Silica Gel can be applies in different way such as either in direct or Indirect Contact.
Applications And Features:
In Direct Contact, this Indicative Silica Gel Blue Beads directly placed along with product to be dried out or free from moisture content such as application like Seed (Non Eatable) drying for storage, research or export, Flower drying for aesthetics, Leaf drying for institutional activity or moisture level balance, Hearing aid instrument box, magnifying and high budgetary Camera lens box etc.
Indirect Contact refers to application of Blue Silica Gel for such application where this will not be in contact with actual product such as Dessicator, Ozone air dryer or Filter, Gear Box desiccant Tubes, Transformer Breathers, Air Dryer Column etc. which facilitate dry or de-moisturized air to final product.
On regeneration it retain its original color i.e. Blue from pink but it is known to be hazardous and toxic in nature due to its cobalt content hence now-a days it is replaced by Silica Gel orange beads having organic dye as an indicator which converts to Blackish green on reaching to equilibrium stage indicating no more adsorption capacity and hence alert for replacement or regeneration.
