Silica gel (ซิลิก้าเจล) คืออะไร ใช้ทำอะไร?? N PLUS CORPORATION CO.,LTD

Silica gel is the most commercial and common desiccant used in food and nonfood products. Desiccants made of silica gel can absorb up to 35% of their weight in water. It removes moisture by a physical adsorption mechanism that can be reversible through temperature change (Batt & Tortorello, 2014). Silica gel is used to maintain dry conditions.


Why Is Silica Gel Used for Product Packaging? Sorbead India

Silica gel is a three-dimensional polymer composed of four-dimensional silicon dioxide units. It is a porous material. Silica gel is a suitable adsorbent for water, alcohol, phenols, amines, and so on. That does this through hydrogen bonds. The adsorption capacity of silica gel at low temperatures is higher than that of alumina and zeolite.

silica gel, a highly porous, noncrystalline form of silica used to remove moisture from gases and liquids, to thicken liquids, to impart a dull surface to paints and synthetic films, and for other purposes. Silica gel was known as early as 1640, but it remained a curiosity until its adsorbent properties were found useful in gas masks during.

Silica gel is a suitable adsorbent for water, alcohol, phenols, amines, and so on. That does this through hydrogen bonds. The adsorption capacity of silica gel at low temperatures is higher than that of alumina and zeolite; however, if the moisture content is low, it is less adsorbent than zeolite.

Silica gel packets work by taking in moisture when there's too much and, if the air gets too dry, releasing some of the water they've already absorbed. The gel itself is basically a mix of water and silica, the main component of sand. Together, the ingredients create pellets that, when examined closely, are made of molecular nets and have.
