Product Description
LPS VINA CO., LTD
As you know, humidity in the air can cause food, goods, and machinery to be damaged. This greatly affects the business production and production activities. In everyday life, we hear and see a lot of Silica gel desiccant particles, but have you ever learned about the composition of the Silica gel desiccant package and its actual use? Silica gel desiccant package products were born as an effective solution to help preserve food and goods for longer. Silica gel is currently the most commonly used desiccant available today. The following article will help you learn more about desiccant particles.

Package - What is Silica Gel desiccant?
Surely you have seen small white packages in confectionery products, medicine jars,... written as "not eaten". Although it is used to absorb moisture, preserve confectionery, medicine, and goods from moisture damage, not everyone understands the composition of the small particles inside.
Silica gel desiccant has a hollow structure, shaped round beads synthesized from silicon oxide. The chemical formula of moisture-proof particles is SiO2.nH2O (n <2), ingredients including sodium othosilicat (Na2SiO4) or Silic TetraClorua (SiCl4). The seeds after fabrication are porous and slightly hard, inside are small empty spaces for water storage.
Silica Gel has a small foam hole inside, spherical or lumpy pellets depending on the method of creating seeds when preparing, there are chisels, transparent like glass. The porosity changes within a limit of about 20-60%, the contact area is 200-800 m2 / g. Usually about 800m2 / g, it can imagine a teaspoon of silica gel with an area. contact size of a soccer field. Porous hole diameter is about 3-10 nm. ). Silica gel particles can absorb water about 40% of its weight.
Silica gel desiccant packs are usually packed into small packages such as filtered tea packages. Inside is a lot of Silica gel particles. This seed is usually 1-5mm in diameter, lumpy or spherical, depending on the method of creating seeds when preparing, when hard to touch. When it is still dry, it will have a slightly green color, when it starts to suck in the steam, it gradually turns light blue, then pink, finally opaque white.
In addition to its strong water absorption capacity, Silica Gel is also used as catalyst due to its porosity properties; adsorption (phase) in color analysis. It is necessary to distinguish the silicagel seeds used to absorb moisture and the type used as a stuffing agent in the column.
