Plastics production include thermoplastics and polyurethanes, as well as thermosets, adhesives, coatings and sealants.
As plastics come in the form of granules, powders or pellets, there are certain ways to mould or shape these materials into products. For the plastics manufacturing process, the material has heat or pressure applied to the plastic or the plastic resins are combined with additives, including fillers and pigments.
As workers perform these manufacturing procedures, they are at risk for being exposed to fumes and fine dust from the plastics either from the machines used for manufacturing or the plastics materials themselves.
The solutions are based on implementing local exhaust ventilation (LEV) systems, generally associated with a general exhaust ventilation (GEV) system.
Local exhaust system is used to manage fume extraction by trapping them at or near the source. Local exhaust is generally a far more effective way of controlling contaminants before they reach the workers' breathing zones. Dedicated equipment includes centrifugal fans and ducting systems.
General industrial ventilation reduces the concentration of the air contaminants, by mixing, with axial fans, the contaminated air with fresh, clean, uncontaminated air. This ventilation system is also known as dilution ventilation.
While workers handle raw materials through grinding or cutting or other finishing procedures for plastic process, fine dust is emitted in the environment. Capture at source, conveying gas and dust, air filtration and dust recovery are the operating principle of a dust extraction installation.
Moreover, a centralized vacuum cleaning system can improve the cleanness of the work places and reduce explosion risks. (ATEX directive)
Plastic pellets, granules and powders are used in plastics industry through processing. These products can be handled with pneumatic conveying systems.
