近年来，西部红杉的供应量减少，其他木材品种正在被考虑作为木瓦和木瓦的替代材料。然而，这些替代品种的木材比西部红杉更容易腐烂。本研究的目的是使用不同的防火测试方法来评估组合阻燃剂和防腐剂处理的防火性能。几种氨基树脂阻燃剂与几种木材防腐剂化合物结合使用，赋予木材阻燃性和耐腐性。处理后的试样进行火管测试，并根据这些测试的结果，两个阻燃剂和两个季铵防腐剂被选择用于额外的防火测试。对这些处理过的材料进行改进的Schlyter试验和燃烧烙印试验。还测量了热释放速率。风化和未风化的标本进行了评价。未风化和风化处理的材料具有良好的耐火性能。
The availability of western redcedar has decreased in recent years, and other species of wood are being considered as substitute materials for wood shakes and shingles. However, the wood of these alternative species is more susceptible to decay than is western redcedar. The objective of this study was to evaluate the fire performance of combined fireretardant and preservative treatments using different fire test methods. Several amino resin fire retardants were used in combination with several wood preservative compounds that imparted both fire retardancy and decay resistance to wood. Treated specimens underwent fire tube tests and based on the results of these tests, two fire retardants and two quaternary ammonium preservatives were selected for additional fire testing. These treated materials were subjected to a modified Schlyter test and a burning brand test. The heat release rate was also measured. Both weathered and unweathered specimens were evaluated. The unweathered and weathered treated material exhibited good fire performance.
