Chemical compounds released by combustion of polymer composites flat belts

Abstract Machines and devices for the production, transport and segregation of products are placed in production and storage rooms. Flat conveyor and drive belts are very often used for their construction. Due to heavy loads and difficult operating conditions, these belts can catch fire and, as a re...

Flat conveyor and drive belts are very often used for their construction.

This article examines the emission level of toxic chemical compounds most often produced during the thermal decomposition and combustion of flat drive and conveyor belts.
