摘要：碳排放量是评估胶合木生产环境影响的重要指标,现有碳排放数据多引用国外和基于理想模型测算,难以真实反映我国当下生产条件碳排放水平。以赤松(Pinus densiflora)胶合木柱为研究对象,基于现场调研分析胶合木柱生产工艺过程的碳排放源,从辅料、能源两个方面建立碳排放边界模型和物料清单,计算产品碳排放量,并分析生产过程碳排放特征,从生产工艺角度提出减碳方式。结果表明:胶合木柱的碳排放量为330.16 kgCO_(2)e/m^(3);锯材生产阶段、胶合木及木柱制作阶段的碳排放量分别占总量的78.5%和21.5%;窑干、接长、施胶、搬运经优化后,可实现碳减排44.3%,优化效果显著。
Carbon emission is an important indicator for assessing the environmental impact of the glulam production.The existing carbon emission data used in China were mostly derived from other countries and based on ideal models,which was difficult to truly reflect the carbon emission level of domestic production conditions.We took a typical glulam column made of Pinus densiflora as the research object,based on the field investigation,the carbon emission sources in the production process of glulam column were analyzed.A carbon emissions boundary model and material list were established from two aspects:auxiliary materials and energy consumption.The product carbon emission and unit process emission characteristics were determined,and carbon reduction modes were proposed from the perspective of production technology.The results showed that the carbon emission of manufacturing glulam column was 330.16 kgCO_(2)e/m^(3);the carbon emissions of the sawn timber production stage and the glulam and wood column production stage accounted for 78.5%and 21.5%of the total,respectively;after the improvement in kiln drying,jointing in length,gluing and transportation,the carbon emission reduction could be achieved by 44.3%,which was a significant optimization effect.
