摘要：
<正>NSCFR flame retardant is one of key factors of non-smoke combustible wood-based materials.Thermal analysis,cone calorimetry,Py-GC/MS, scanning electron microscopy（SEM） were utilized to investigate the flame-retardation and smoke-suppression characteristics and mechanisms of NSCFR flame-retardant.The results show that NSCFR flame-retardant could significantly shorten the combustion duration of wood-based materials and completely eliminate the second peak of heat release rate curve,greatly reduce heat release rate, total smoke release,mass loss rate,specific extinction area,and carbon monoxide production and carbon dioxide production,obviously enhance the mass of combustion char residue,effectively retarding the combustion and inhibiting smoke release of the wood-based material;NSCFR flame-retardant exhibits the ability of flame retardancy on wood by the conjunct mechanism of capturing free radical, diluting combustible gas,and catalyzing charring; NSCFR flame-retardant displays smoke suppression effects on wood by absorption action of nano alveolate structure together with the active catalyzing action of ironic molybdate.
摘要：
With the development of plantation forestry, poplar tree has become one of the most useful plantion species for the composite biomaterials in China. Therefore, the thermal release behavior of poplar composite biomaterial under high temperature was studied by TD-GC/MS in order to reveal environmental protective performance. The results were: (1) The main constituents of thermal release volatiles at 90 degrees C were acetic acid (81.45%), furfural (2.66%), cedrol (1.7%), formic acid (1.67%), benzenemethanamine, N-hydroxy-N-(p henylmethyl)-(1.42%), 2-propanone, 1-hydroxy-(0.88%), 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) ester (0.66%), etc. (2) The main constituents of thermal release volatiles at 150 degrees C were acetic acid (68.55%), furfural (7.26%), formic acid (7.22%), 2-propanone, 1-hydroxy-(2.22%), thiourea (1.96%), 2-furancarboxaldehyde, 5-methyl-(1.82%), propane, 2-ethoxy-(1.37%), 2-furanmethanol (1.32%), 2-pentanone (0.72%), 1H-pyrrole-2-carboxaldehyde (0.72%), etc. The result revealed that the poplar composite biomaterial is safe under high temperature, but its fire risk rised up.

摘要：
Human living environmental problems are increasingly serious, wood environment science has conformed to this subject. The author introduced three domains of wood environment science in detail, Elaborated research achievements of these domains, Analyzed research on the wood environment science the role which plays to the human living environmental protection, proposed the wood environment science in our country's futurology research direction and the goal.
摘要：
The wood-based panels industry is the core industry of the comprehensive utilization of wood and conservation of forest resources in China and it is also the important component to guarantee the sustainable development strategy of the forestry. However, a great deal of energy and resources is consumed and the various additives such as the adhesives, the water-repellent, etc. are used in the production process of the wood-based panels, so the wood-based products will causes the environmental pollution and the resource recovery rate of the products will be also declined. This paper studied the production process of a certain particleboard factory in China, analyzed the environmental characteristics of the particleboard production process, explored the critical factors to cause the environmental load from the aspects of the energy consumption, the raw material consumption, the environmental impact and so on, so that it provided the foundation for improving the processing technique of the wood-based panels and reducing the environmental pollution.
