Storage condition
Storage Precautions Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir shall not exceed 35℃, and the relative humidity shall not exceed 80%. The package must be sealed and protected from moisture. It should be stored separately from easy (can) combustibles and acids, and should not be mixed. Storage areas should be equipped with suitable materials to contain leaks.

stability
1. Strong alkaline, solid caustic soda has strong hygroscopicity. Easy to dissolve in water, heat release when dissolved, the aqueous solution is alkaline, there is a slippery sense; Extremely corrosive, corrosive to fiber, skin, glass, ceramics and so on. React with aluminum and zinc, non-metallic boron and silicon to release hydrogen; Disproportionation with halogens such as chlorine, bromine and iodine; Neutralize with acids to form salt and water. Staff should take good protection, if accidentally touch the skin and eyes, should immediately rinse with plenty of water. The working environment should have good ventilation conditions. Easy moisture, soluble in water, ethanol, glycerol (glycerol). The water solution is greasy and produces high heat when dissolved in water. Wear protective eyepieces and rubber gloves when operating. Be careful not to splash into the skin or eyes. In case the skin can be washed with 5% to 10% magnesium sulfate solution, and then rinse with a lot of water, into the eyes with boric acid water and a lot of water.
