Well, I do not recall exactly but I Do recall times when I wondered what they were, I opened them and put a few diamonds in my tongue I believe my dad told me to just to feel how they stick to it. Well, the vast majority of the time, these very small packs that we find are silica gel desiccant packs used to absorb moisture, but there are more types of desiccants with many more and diversified used. In another article I will discuss about the main ones so keep reading. The most known and used Type of desiccant manufacturers. It is a natural occurring mineral called silicon dioxide SiO2 that is processed and processed to beaded or granular form. As temperature goes above 100°F, the rate of moisture absorption will slow down but it will still work. Silica gel works best at room temperatures and higher humidity 60- 90% RH and will fall the relative humidity in a container down to about 40 per cent RH. It is widely utilized in food and pharmaceutical applications as it is the sole desiccant approved by FDA for direct contact with these products.
Activated Carbon
Activated carbon or activated charcoal How it is also called is different from ordinary charcoal because it moved through an activation process and it is also free of fossil fuels that are poisonous. Its surface area is dramatically increased in the activation process which adds the exceptional absorbing ability. Activated carbon has the ability to absorb pollutants, toxins or chemical spills when used in agriculture. It is great medicinal properties used to treat infections and colic, diarrhea, open wounds, spider bites or bees, ants and scorpion bites, food poisoning. Plus, the treats drug overdose, gas, diabetic ulcers, heartburns and indigestion. As it owns such excellent absorption capacity, activated carbon is also used for water and air filters. It will absorb gases and odors, plastic fumes, cigarette smoke, furniture glues, carpet odors, bacteria and viruses. Activated charcoal filters out harmful elements from water like chlorine, copper or carbohydrates.
Molecular sieves are porous synthetic pharmaceutical desiccant that have a very strong affinity for moisture molecules. In comparison to the other desiccants, the distinguishing quality of the molecular sieve structure is that the uniformity of the pore size openings in the crystal lattice structure. Part of the manufacturing process, the pore size on the molecular sieve particles is controlled allowing the option of a product which can absorb water, nevertheless exclude a number of different molecules, such as volatile organics, which might be present in the package or others that may absorb a wide range of molecules along with moisture.
