Silica gel is produced synthetically from sodium silicate, which is a porous but granular form of silica. It is utilized as a desiccant or moisture adsorbent to manage humidity levels locally in order to avoid degradation of the goods.Silica gel blue crystals are known asself-indicating type desiccants and are prepared by infusing white silica crystals in cobalt chloride. These crystals are hard in nature and are placed in breather because of their quality of absorbing moisture considerably. Breathing process of a transformer includes in and out flow of air due to thermal contractions and expansions created because of oil inside Continue Reading->
Keeping aside the moisture and water of the air is very important in many industrial sectors. Moisture can have a negative impact on many industrial products. This is why different types of moisture absorbers are used. Indicating silica gel is one of the premium absorbers used in the industrial sector. It is also popular as blue silica gel and is available in different mesh sizes. Some of the advantages of this gel are it doesn’t show any chemical reactions, it is tasteless, odorless, non-toxic. It adsorbs comparatively large amount of water. What is interesting about this gel is that it changes its color while adsorbing moisture from the air. It turns purple from blue and then turns to pink from purple.
This gel can absorb water more readily than any other liquids or gases simply because of its high affinity to water. But it can also adsorb other substances like hydrocarbons of gasoline range, sulfur, nitrogen elements, CO2 etc. It is used vastly in many industries for different kinds of applications which require high-quality as well as high capacity adsorbent.
Silica Gel Indicating is used in the retail industry for packaging purposes. Various electronics and medicine products are packaged using this gel so that moisture can’t cause any sort of damage to the product. It is also used for packaging foods that require moisture free atmosphere. It doesn’t cause any changes to the nature and feature of the products. Silica gel packets can be used to prevent mechanical failures as well. In cases where moisture build up causes mechanical failure, the compressed air is circulated through those packets so that the moisture gets adsorbed. This combined system is used for radio transmission system as well.
Silica Gel Blue Beads is also used for the preservation of important documents and papers in libraries and in museums. Due to the age of those documents, those are very sensitive to moisture and can lost its originality or quality when get in touch with moisture. It is also used in cat litter and storage units where products are stored for long terms. Industries where these blue beads are used are air dying industry, pharmaceutical industry, gas industry, food industry and leather and textile industry. And the way its importance and acceptance is increasing, in coming future this gel may be used in many other industries.
Let’s have a quick look at the vast use of this gel. Dehydration procedure, absorbing moisture from sealed vessel, refrigeration, air conditioning, purification of natural gas, storing dehydrated foods, electronic equipments packaging, leather products packaging, pharmaceutical products packaging etc.
