    Possible quality problems of styrene during storage and measures to be taken
      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.

    Characteristics and applications of styrene
      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.

    Chemical properties of styrene
    Styrene is a liquid at room temperature, colorless, with a pungent odor, styrene is flammable, boiling point 145.2 degrees Celsius, freezing point of -30.6 degrees Celsius, specific gravity 0.906, styrene is insoluble in water, if at 25 degrees Celsius, styrene solubility is only 0.066%. Styrene can be mixed with ether, methyl ferment, carbon disulfide, acetone, benzene, toluene and tetra-ironic carbon in any proportion. Styrene is a good solvent for natural rubber, synthetic rubber and many organic compounds. Styrene is toxic and can cause poisoning if the human body inhales too much styrene vapor. The allowable concentration of styrene in the air is 0.1mg/L. Styrene vapor and air will form an explosive mixture.

    Polystyrene
    Polystyrene (PS) is a polymer synthesized from styrene monomer by free radical addition reaction, the chemical formula is (C8H8)n. It is a colorless and transparent thermoplastic with a glass transition temperature above 100°C, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, and disposable foam lunch boxes, etc.
