儲存與處理

Styrene Monomer is stored in insolated carbon steel tanks. To prevent Styrene polymerization, the Styrene temperature must be controlled at around 10-11°C. Also, a polymerization inhibitor must be added. Normally, Tertiary Butylcatechol (TBC) is used with a concentration of 10-15 PPM. In hot climates and during the transportation of Styrene, the initial TBC level should be increased to around 50 PPM to avoid autocatalytic polymerization which becomes self-sustaining above 20°C. The exact TBC level will depend on the prevailing ambient temperature and the duration of the transportation. As a general rule when transporting Styrene, you should avoid contact with copper, copper alloys, brass and PVC. Avoid contact of Styrene (containing low level of TBC) with oxygen as it creates hazardous peroxides. Avoid contact with air. Avoid static electricity, sparks or any open flame. Keep liquid temperature and vapor venting under rigged control. Avoid direct or prolonged exposure to the sunlight and ambient conditions. Indoor storage should be in a standard flameproof storage room with temperature controlled lower than 25°C. Use safety goggles, rubber gloves and chemical cartridge respirators.
