Another type is packaged using double-wall corrugated boxes and plastic bags; the inner packaging consists of polyethylene plastic film bags, with each bag containing a net weight of either 1 kg or 0.5 kg. The outer packaging is made of corrugated boxes, with each box having a net weight of 25 kg and 20 kg respectively. Storage and transportation: During storage and transportation, it is strictly prohibited to store it together with other goods. Care should be taken to keep the packaging intact. Sodium percarbonate should. Store in a dry and well-ventilated warehouse. Precautions: a: After wiping the relevant utensils with this product, they must be dried with a clean cloth (or rinsed with clean water). b: This product is not suitable for washing or wiping woolen garments. c: After opening the bag, store this product in a dry and well-ventilated place. d: During storage and transportation, the ambient temperature must not exceed 40°C.
Scientific name: Sodium percarbonate； Common names: sodium percarbonate, percarbon, solid oxygen. Molecular formula: 2Na2CO3·3H2O2; Relative molecular mass: 314.02 (based on the 1991 international relative atomic masses). Characteristics: white crystals or crystalline powder. Soluble in water, it rapidly releases oxygen; its aqueous solution is alkaline. When exposed to heat, humid air, or impurities, it easily decomposes and loses oxygen. Uses: Mainly used as a bleaching agent in detergents, a dyeing and finishing agent in the textile industry, a desiccant, a treatment agent for metal surfaces, a disinfectant for food hygiene, a deodorizer, an oxygen generator, a water purifier, an oxygen and water purification agent for aquaculture, a disinfectant for medical and health purposes, and a preservative. Sodium percarbonate is commonly known as solid hydrogen peroxide. At room temperature, it dissolves rapidly in water and dissociates into sodium carbonate and hydrogen peroxide. The free hydrogen peroxide then further decomposes into water and atomic oxygen under alkaline conditions, thereby exerting oxidizing, bleaching, and bactericidal effects. Taking the bactericidal effect as an example, a newly prepared 1% aqueous solution of sodium percarbonate can kill Staphylococcus aureus, Shigella flexneri, Salmonella typhi, Bacillus anthracis, and other bacteria within 3 minutes. Sodium percarbonate is primarily used as a bleaching and bactericidal additive in daily chemical cleaning products. It is employed in the bleaching of synthetic fibers, animal fibers, resin-treated fibers, and fibers treated with fluorescent whitening agents. After washing, the fabrics do not yellow, and the fibers remain undamaged. Additionally, it can be used as a dyeing and finishing agent in the textile industry, a steel refining agent, for disinfecting and cleaning equipment in food factories, for cleaning dentures, for cleaning bathtubs, and for bleaching and cleaning animal intestines and large intestines. Utilizing sodium percarbonate as a source of oxygen, it has gained increasing attention in recent years. Besides serving as an oxygen source for medical emergencies and field first aid, it is also employed in the aquaculture industry, such as in the transportation of live fish and the cultivation of kelp
So, what is the production process?
This post was last edited by 9067jxhuas on March 18, 2010, at 13:59. The low-temperature crystallization method is employed; additionally, a raw material purification process is added. The purified sodium carbonate solution and hydrogen peroxide are simultaneously added to the reactor, and the reaction crystallization is carried out by controlling the flow rate, rotational speed, and temperature. Additionally, there is an article on Haichuan: http://bbs.hcbbs.com/thread-132733-1-1.html Research on the process for producing sodium percarbonate with high stability

I’ve learned something new. Thank you, dear friends! I hope those interested in this knowledge will continue to learn more.
Excuse me, what does “Moisture content (%) ≤ 2 2” mean? It’s not “22”, but “2 2”"
