Mainly used in heat storage stage during the process of solar heat storage and power generation, make use of function of heat storage that mixtures of sodium nitrate, potassium nitrate and other materials storage has at a high temperature molten state.
Packaging:
In woven bag lined with PE bag, 5kg-1,500kg per bag. The package bag can be customized.
Protection Measures:
Working personnel should wear breathing masks to protect respiratory organs and wear overalls and latex gloves to protect the skin.
Storage and Transportation:
Sodium nitrate shall not be stored and shipped with gauze, paper, oil, sugar, wood, sulfur, organics, acids, alkalies and other oxidants; be kept away from rain, sunshine and moisture during the transportation; be treated with care in loading and unloading to prevent friction, impact and packaging breakage. Sand should be used firstly, and then water or a variety of fire extinguishers when it catches fire, but aqueous solution should be avoided to contact with combustible materials.
