Liquid chlorine
Properties: Liquid chlorine is clear yellow liquid with a high vapor pressure and a strong pungent odor. The boiling point is -34.05°C under standard conditions. Solid chlorine is a pale yellow rhombic crystals with a melting point of -100.98°C. The density of liquid chlorine at 0℃ is 1468kg/m3. The vaporization volume of 1 liter of liquid chlorine at 0℃ is 300 liters.
Handling and Storage: packaging materials are manufactured by nation designated professional factory for producing pressure vessels, including the production of liquid chlorine cylinders. There must be shading devices for both transport vehicles of liquid chlorine cylinder and storage facilities to prevent them from direct exposure to sun lights. The temperature of liquid chlorine cylinder should not exceeding 40 ℃ during transportation and storage. When in transportation, the mouth of cylinders should be directed toward the right side of driving direction. The empty bottles should be separated from the filled ones with no exception.
Sodium hydroxide
Properties: Sodium hydroxide and its aqueous solution have a strong corrosive effect on animal and plant tissues (such as skin, silk and wool fabric, paper) and other organic substances. In particular, it can cause a change in the internal structure of steel and silicon-containing materials and a reduced strength.
Handling and Storage: Since Sodium hydroxide has a strong chemical corrosive effect and can react with silicate, aluminum, zinc and others, therefore, carbon steel or stainless steel containers should be used for sodium hydroxide storage and transportation. The containers should be closed tightly during transportation and storage since sodium hydroxide can react with CO2 in the air and produce Na2CO3. |
