According to reports, the concentration of styrene vapor in the unsaturated polyester resin glass fiber reinforced plastic processing workshop under natural ventilation is generally 500-550 mg/m3; when the exhaust fan is installed, it is generally 200-400 mg/m3, which is higher than national regulations.
Therefore, one of the methods is to increase the ventilation intensity, set up sufficient ventilation devices in the workshop, minimize the amount of resin storage in the workshop, and seal the resin packaging barrel after use. It should be noted that the vapor density of styrene is higher than that of air. The concentration of styrene is high on the ground, so the suction port of the ventilation device should be close to the ground.
Adding styrene volatilization inhibitor to the resin also has an effect.
