Calcium peroxide specification

Calcium peroxide appears as a white or slightly yellowish powder, is odorless and tasteless, and is only sparingly soluble in water but soluble in acids. It is a highly stable peroxide; its dry form does not readily decompose at room temperature, but decomposition begins at 275°C. In moist air or water, it can slowly release oxygen over an extended period. Additionally, it possesses strong bleaching, bactericidal, and disinfecting properties and is environmentally safe.

Product Application

Due to its excellent stability, non-toxicity, and ability to generate oxygen over an extended period, calcium peroxide has become a widely used, multifunctional inorganic peroxide. In environmental protection applications, it can be utilized to improve surface water quality, treat wastewater containing heavy metal particles, and mitigate red tides; in agriculture, it is employed for oxygenating plant root systems, biochemically improving soil quality, coating rice seeds, serving as an oxygen fertilizer, or as a component of bio-complex fertilizers; in aquaculture, it acts as an oxygen release agent to increase dissolved oxygen levels in water, regulate water pH, enhance water quality, and eliminate pathogenic bacteria; in food processing, calcium peroxide can be used for preserving food and fruits/vegetables, as a feed additive, for improving dough quality, or for food disinfection; in the metallurgical industry, it is used for phosphorus removal and the extraction of precious metals; in the rubber and chemical industries, it serves as a vulcanizing agent for natural rubber, a hardening/enclosing agent for polysulfide rubber, or an initiator for unsaturated polyester resins; additionally, calcium peroxide can be used in the daily chemical industry as a tooth cleaning agent or a household disinfectant and deodorizer; furthermore, it finds applications in emergency oxygen supply, cigarette manufacturing, and the coatings industry.

Storage Precautions

Oxidizing agent! Store in a dry, clean warehouse with good ventilation. Keep away from sources of ignition, heat, and direct sunlight. Take care to protect against moisture and rain exposure. Ensure the container is tightly sealed and verify that the label is intact and legible. Handle with care during loading and unloading to prevent damage to the packaging or container; ensure that the container pressure is properly released. Transportation is not recommended during rainy weather. Store separately from flammable or combustible materials, reducing agents, sulfur, phosphorus, etc.; avoid mixed storage or transportation. Prevent contact with any substances that may cause the product to decompose.
