阻燃氨基树脂对胶合板燃烧时CO和CO2释放的影响
Influence of inrumescent flame retardants and the amino resin on CO and CO2 production of wood materials
摘要
Abstract
[Objective]The influence of intumescent flame retardants and amino resin (IFR-MUF) on CO and CO2 production of wood materials was investigated.[Method] CO and CO2 production of Eucalyptus saligna,E.saligna plywood,and E.saligna flame-retarding plywood was studied using a cone calorimeter (CONE) at 30 and 50 kW/m2.[Result]The rate of CO2 production was highest during ignition and carbon combustion stages.The rate of CO production was highest at the smoldering stage,while the most significant effect of the radiance level on CO production rate was observed during carbonization.The utilized amino resin promoted the integrity of char layers,negatively affecting smoke release during the carbonization stage and enhancing CO2 production during the carbon combustion stage.The thermal conductivity of the carbon layer was higher than that of the airmade 2nd peak of the CO and CO2 production rate curves earlier.The effect of IFR-MUF on CO production was closely related to radiance levels,with CO emission yields being markedly increased at lower radiance levels.[Conclusion] The trend observed for the CO2 production rate agreed with that of the mass loss rate,being slightly affected by radiance levels.IFR-MUF increased CO emission yields and decreased those of CO2.关键词
