Silica gel and its advantages as a desiccant

What is Silica gel

Silica gel is formed from silica, which is amorphous and can be synthesized into hard particles. Because of their microporous makeup with interlocking cavities, the gel has an extremely high surface area, making it a perfect high-capacity desiccant. Because its vapor pressure is lower than the surrounding air, water molecules easily attach to its surface. When equal pressure is established, absorption is no longer possible. Therefore, the higher the humidity in the air, the higher the water absorption. It is important to note that high humidity, especially above 50%, may damage the gel being transported or stored.

What is a desiccant dryer

Desiccant dryers are commonly used to dry air for various applications. This type of dryer removes water molecules from the surrounding air through a desiccant that can absorb water molecules. While there are manual desiccant dryers, many are regenerative. The dryer has two cylinders that are connected by a valve system and contain a desiccant material such as silicone. When the first desiccant cylinder is saturated, air can then enter the desiccant-filled cylinder.

Benefits of Silicone Desiccant Bags

  • Absorption is when one substance combines with another substance. These substances change when they interact. Adsorption is when one substance sticks to the surface of another substance, but they both remain the same. Every substance retains its original properties. Adsorption is what happens when a desiccant is used. Desiccants remove moisture and slow down processes that can damage food or create mold and odors on surfaces.
  • Moisture is the presence of water or other liquids in the air. Moisture floats as a gas until these liquids collect on the surface. On the surface, the moisture returns to a liquid state that can be absorbed by food, paper or other items. When this liquid builds up on the product, a chemical reaction occurs that damages the material. In order to maintain the quality of food, technology, paper products or other valuables, it is important to minimize the amount of moisture on the surface of these items.
  • Silica gel desiccant beads (SIO2) consist of one silicon atom linked to two oxygen atoms. This combination is found in small pieces of sand and large stones and is very effective at absorbing moisture. When these atoms are processed into silica gel desiccant beads, they contain millions of pores that can hold moisture. This adsorption process keeps the silica and moisture separate. The beads can hold up to 40% of their weight in moisture. Moisture fills pores and does not allow moisture to reach the surface of the product. Silicone drying beads are essential for maintaining the integrity of valuable products such as paper, food and leather.
  • Beads are available in large quantities or can be purchased as pre-made silicone desiccant bags. These bags allow for simple, clean and safe packaging. All products can benefit from adding data packages to your production system. Whether storing or transporting, silicone desiccant bags are an affordable and effective way to ensure a longer product life. The benefits of silicone desiccant bags go beyond protecting the product during shipping to the customer. Customers can continue to use the silica gel desiccant bags for their own use. Below are some examples of reused silicone desiccant bags.

At home:

  • Protect collectibles large and small, including ornaments, collectible coins and other valuables
  • Add to filing cabinet to keep files
  • Storage for hearing aids and other technical storage...computer cases!
  • Set near windows to prevent condensation from warping the wood frame
  • Add to picture storage box to ensure color retention
  • Put on the bottom of wet boots and shoes
  • Add to laundry basket or put in locker for laundry

At work place:

  • Keep files and content in your desk drawer
  • in the trash can
  • in the tool drawer
  • In and near computer/tech storage areas

In fun and spare time:

  • Sewing basket keeps needles from rusting
  • Tackle Boxes and Tool Boxes
  • storage container with garden seeds
  • Boat, motorcycle, rear vehicle storage area
  • Silica gel desiccant bags need to be restored to continue effective adsorption. To reactivate the silicone, it needs to be heated. The heat causes the moisture to turn into a gas and move atoms into the atmosphere. Since the beads and liquid each retain their original chemical properties, the water leaves the pores when heated. Silicone bags are ready to be used again to help remove moisture and protect your product.

New year, new semester, not the same old thing. This semester will be a semester to redeem all the mistakes made in the previous five months.

1. I will wake up (sorta) on time for class.

Let's face it, last semester you woke up with enough time to brush your teeth and get to class and even then you were about 10 minutes late and rollin' in with some pretty unfortunate bed head. This semester we will set our alarms, wake up with time to get ready, and get to class on time!

The 5 Painfully True Stages Of Camping Out At The Library

For those long nights that turn into mornings when the struggle is real.

And so it begins.

1. Walk in motivated and ready to rock

Camping out at the library is not for the faint of heart. You need to go in as a warrior. You usually have brought supplies (laptop, chargers, and textbooks) and sustenance (water, snacks, and blanket/sweatpants) since the battle will be for an undetermined length of time. Perhaps it is one assignment or perhaps it's four. You are motivated and prepared; you don’t doubt the assignment(s) will take time, but you know it couldn’t be that long.

December... it's full of finals, due dates, Mariah Carey, and the holidays. It's the worst time of the year, but the best because after finals, you get to not think about classes for a month and catch up on all the sleep you lost throughout the semester. But what's worse than finals week is the last week of classes, when all the due dates you've put off can no longer be put off anymore.

Top 20 Thoughts College Students Have During Finals

The ultimate list and gif guide to a college student's brain during finals.

winter

Thanksgiving break is over and Christmas is just around the corner and that means, for most college students, one hellish thing — finals week. It's the one time of year in which the library becomes over populated and mental breakdowns are most frequent. There is no way to avoid it or a cure for the pain that it brings. All we can do is hunker down with our books, order some Dominos, and pray that it will all be over soon. Luckily, we are not alone in this suffering. To prove it, here are just a few of the many deranged thoughts that go through a college student's mind during finals week.

I know every college student has daily thoughts throughout their day. Whether you're walking on campus or attending class, we always have thoughts running a mile a minute through our heads. We may be wondering why we even showed up to class because we'd rather be sleeping, or when the professor announces that we have a test and you have an immediate panic attack.
