1. Different ingredients

The main ingredient of Hanging Moisture Absorber is calcium chloride. Then calcium chloride is a deliquescence crystal, its color is generally white, and it will be liquid after absorbing water. Some dehumidifiers also add related fragrance ingredients, which can add fragrance to the indoor environment while dehumidifying.

The desiccant component is mainly silica gel or calcium oxide. Then the most common desiccant on the market is silica gel desiccant, which is a translucent granular material, which is formed by silicate plus acid or ammonium salt precipitation and activated at high temperature. Silica gel has a large adsorption area and can effectively absorb moisture in food.

2. The principle is different

Calcium chloride is highly hygroscopic, but has a strong irritant, so it should not be in direct contact with the human body, otherwise it will easily cause redness, swelling, heat, pain and inflammation of the mucous membrane or skin. The desiccant can be placed with food, and the silica gel desiccant will not be absorbed by the gastrointestinal tract, so it will not cause toxicity and will be excreted with the feces. However, after the calcium oxide desiccant absorbs water, it will become calcium bicarbonate, and at the same time, it can no longer absorb water, and has a certain toxicity, so there are still more silica gel desiccant products on the market.

3. Different occasions

The main products of Hanging Moisture Absorber are dehumidification boxes, dehumidification bags, etc. Strong Hanging Moisture Absorber is generally used in the home environment, mostly used in wardrobes and shoe cabinets to prevent moisture.

Desiccant can be divided into silica gel desiccant and calcium oxide desiccant according to its components, so it is generally used more in industry.
