Product Description

Product Description

Orange silica gel, also known as "cobalt free color changing silica gel", is an environmentally friendly desiccant and belongs to silicone products. The appearance is orange translucent glassy particles. It has strong moisture absorption ability and its appearance color will change significantly with the increase of moisture absorption during the moisture absorption process. When not damp, it is orange yellow, and gradually turns green or dark green as it absorbs more moisture.

Orange silica gel not only has blue adhesive properties, but also has the advantages of not containing cobalt ch-loride, being non-toxic and harmless. Used in conjunction to indicate the degree of moisture absorption of desiccants, in order to determine the relative humidity of the environment.

Application:
1. Mainly used for drying, moisture absorption, rust prevention, and indicating the relative humidity or dryness level of the environment.
2. Widely used in precision instruments, pharmaceuticals, food, clothing, home appliances, petrochemicals, and other industrial gases.

Blue silica gel has the adsorption and moisture-proof effect of fine pore silicone. Its characteristic is that during the moisture absorption process, it can turn purple with the increase of moisture absorption, and then turn light red. It can indicate the humidity of the environment and visually determine whether a new silicone gel or regeneration is needed.

Blue silica gel can be used alone for moisture absorption. Due to its color changing characteristics, it is usually used in conjunction with ordinary silicone desiccants to indicate the degree of moisture absorption of the desiccant and determine the relative humidity of the environment.

Application:
1. It can be used independently for moisture absorption and is widely used for moisture-proof packaging of precision instruments, clothing, food, medicine, and household appliances.

Due to its color changing properties, it is usually used in conjunction with ordinary silica gel desiccants to indicate the moisture absorption level of the desiccant and determine the relative humidity of the environment.
 

Transparent silica gel, which is a transparent spherical particle, is a type of silica gel desiccant. It is a non chemically reactive crystalline form of silica gel
The interior has an extremely fine pore network structure that can absorb water and retain it through its physical attraction.

Application:
1.Mainly used for drying and waterproofing (such as storage of food, electronic products, clothing, and other products)
2.Used as a catalyst carrier, adsorbent, separator, and pressure swing adsorbent.
