In leather products and foods like pepperoni, the lack of moisture can limit the growth of mold and reduce spoilage. In electronics it prevents condensation, which might damage the electronics. If a bottle of vitamins contained any moisture vapor and were cooled rapidly, the condensing moisture would ruin the pills. You will find little silica gel packets in anything that would be affected by excess moisture or condensation.
Silica gel is nearly harmless, which is why you find it in food products. Silica, or silicon dioxide (SiO2), is the same material found in quartz. The gel form contains millions of tiny pores that can adsorb and hold moisture. Silica gel is essentially porous sand.
Silica gel can adsorb about 40 percent of its weight in moisture and can take the relative humidity in a closed container down to about 40 percent. Once saturated, you can drive the moisture off and reuse silica gel by heating it above 300 degrees F (150 C).
Tech Guru Facts.
Silica Gel is reusable so don’t throw it out.
If you ask what is use of keeping it then let me say something.
Silica Gel Uses
- If your mobile phone falls in water or in sea or anywhere the real problem for the electronics is the moisture. So If this situation happens get some silica get and keep it with your wet mobile phone. It absorbs moisture so the chances for your phone recovery will be doubled or tripled or greater than that.
- Waterproof cameras are super fun but sometimes the condensation can end up damaging the camera or leave a fog streak across your lens. Stop this from happening by storing a packet or two of silica-gel packets in the camera case or with the camera. It will dry all of the excess water out.
- Oxidation and moisture is the reason that razor blades fall to pre-mature dulling. A good tip is to keep a Tupperware half full of silica gel near by and after shaving, blot dry your razor and store the razor in the closed Tupperware that has 4 -5 silica gel packets.
- If you toss a few packets of silica gels into a Ziplock bag, it has enough water and moisture fighting ability to withstand any spills.
- If you like to sew, or use fabric for craft projects, keep a few of the silica packets with the fabric in a plastic or Ziplock bag to keep the moisture out.
- Put silica gel packet in the boxes where you store your photos to keep them safe and dry.
- These tiny packets can do a great job of keeping luggage dry. You can simply toss a few silica gel packets into your luggage to keep it moisture and odor-free. This could really help to extend the life of your luggage.
- If you love to dry flowers, these can be used in a cinch to help the process go faster. Store in a paper bag with the a couple packets.
