Problems
The main problems are the generation of polymers, color change and the generation of impurities.
Second, the main factors that cause these problems and styrene storage should take the following important measures
1, a reasonable selection of storage tanks
Line SH/T3007-2007 article 4.2.5 states: "Some A A, B B chemicals have special storage needs, can not be used within the floating top tank. Such as styrene, in order to inhibit the polymerization needs to contact with oxygen, although styrene is a class B A liquid, but its tanks can only be used to fix the top tank." The internal structure of the fixed-top tank should be simple, the internal surface of the tank should be smooth, clean, no scars, weld tumors, minimize crossbeams, tie rods, etc., to avoid the condensation of styrene vapor accumulation. And the tank structure design must be considered to prevent styrene polymerization when the flow of hanging on the tank wall measures.
Styrene is an organic compound that can be formed by both benzene and ethylene. It is a colorless and transparent liquid that is very easy to contaminate drinking water, soil and surface water, and has strong volatility and is easily volatile under light environment, so it is often stored and transported in steel drums. Currently it is widely used in synthetic resins and rubber, such as polystyrene, ABS resin and other engineering plastics.
