COMPARISON OF SMOKE, CARBON MONOXIDE AND CARBON DIOXIDE EMISSION FROM NATURAL AND MAN-MADE POLYMERIC MATERIALS

摘要

The inherent elements of thermal decomposition and combustion of materials is a smoke which reduces visibility and toxic gases contained in the smoke.The paper presents the results of studies of the emission of smoke, carbon monoxide and carbon dioxide from natural and synthetic fabrics (flax, cotton, wool, hemp, polyacrylic, polyester), lignocellulosic materials (wood, chipboard, fibreboard), polyurethane foam and polypropylene.The flammability measurements were carried out using a cone calorimeter at exposition to heat fluxes of 25, 35 and 50 kW/m~2.Moreover, the influence of air-flow intensity on the formation of smoke, carbon monoxide and carbon dioxide was investigated. Three air-flow intensities used were: 0,015, 0,024 and 0,035 m~3/s.
