Storage

Firstly, under normal temperature, airtight and dark, ventilated and dry inert gas. And then, stored in a cool and dry warehouse, and the warehouse temperature should be below 40 ℃ to avoid high temperature. Further, pay attention to moisture-proof, and seal the package. Keep away from heat and fire. Secondly, stored and transported together with reducing substances. During transportation, it shall be protected from rain and sun. In addition, during loading and unloading, handle it with care to prevent package damage. The storage stability of coated sodum percarbonate is greatly increased.

 

Application

Firstly, Milk fresh-keeping agent. The general dosage is 50mg/kg, which can keep fresh for 7-8h at 30 ℃ and 5-6d at 3-5 ℃.

And then used as the raw material of low phosphorus and non phosphorus laundry powder, as the rinsing agent, reducing developer in the textile industry, and also as the disinfectant, bactericide, deodorant, etc.

As bleach and oxidant. Its use is similar to that of sodium perborate. When used as bleach additive of detergent, the total water content of detergent shall be no more than 2% to avoid affecting the stability of sodium percarbonate. It is also used as bleach in paper making, textile and other industries, as well as as cleaning agent for public facilities and medical disinfectant.
