COMPOSITION

This substance has silicon dioxide as its primary component, and its color changes in response to humidity. In addition to the performance characteristics of blue silica gel, it also features being cobalt - chloride - free, non - toxic, odorless, and harmless.

 Its molecular formula is (SiO_{2}+H_{2}O + C_{25}H_{30}ClN_{3}). Please note that the symbol for chlorine in the formula should be “Cl” rather than “CL” for correct chemical notation.

PERFORMANCE AND USAGE

In 1998, the European Union classified cobalt chloride as a category - 2 carcinogen. In Europe and the United States, the production of blue silica gel containing cobalt chloride has been prohibited, and it shows a trend of being gradually phased out. To meet market demands, our company developed cobalt - chloride - free orange silica gel. This product can be used independently or mixed with other silica gels. To dry substances and indicate humidity, an appropriate amount of the product can be placed in suitable containers or packaging. This product is mainly applied for drying, indicating the degree of dryness or humidity, and is widely used in precision instruments, pharmaceuticals, petrochemicals, food, clothing, leather, home appliances, and other industrial gases. It can also be used domestically for moisture - proofing and dehumidifying purposes. Orange silica gel has a strong moisture - absorption capacity. During the moisture - absorption process, its appearance color changes significantly according to the amount of absorbed moisture. Therefore, it is often referred to as a "humidity indicator."

PHYSICAL CHARACTERISTICS

TECHNICAL SPECIFICATION

### Product Specification The product is available in the following particle sizes: 1 - 3mm, 2 - 4mm, 2 - 5mm, 3 - 5mm, and 4 - 8mm. ### Packaging Material - For smaller - scale packaging:    - 25KG per bag or 500KG per bag, which can be packed in plastic bags or compound bags. - For larger - scale packaging: One - ton bags are also available. - Additionally, other packaging options include steel drums, paper cans, cartons, plastic bottles, polyethylene plastic compound bags, and flexible container bags. ### Packaging and Storage Orange silica gel has a strong moisture - absorption capacity. To maintain its quality, it must be stored in a dry location. When storing, place shelves or pallets between the ground and the goods to prevent moisture absorption from the ground. During transportation, it is crucial to keep the product away from rain, damp environments, and direct sunlight to avoid any negative impacts on its performance.
