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:
Reed, who lives in all over the world, is one of renewable ecological materials for harvest per year. The environmental protective performance for warm-compaction reed material was studied by GC/MS in order to reveal achievements and existent problems. The main constituents of volatiles at 40°С were. acetic acid(75.08%), di-n-octyl phthalate(3.48%), (+)-epibicyclosesquiphellandrene(1.85%), 2-propanone, 1-hydroxy-(1.69%), [1,1':3',1''-terphenyl]-2'-ol (1.53%), propylene glycol(1.26%), furfural(1.25%), caryophyllene(1.03%), cedrol(0.95%), etc. The main constituents of volatiles at 60°С were acetic acid(72.98%), cedrol(2.35%), 1,2-benzenedicarboxylic acid, diis ooctyl ester(1.97%), hexadecane(1.45%), 1-ethyl-3,3-bis (trifluoromethyl)diaziridine(1.45%), 2-propanone, 1-hydroxy-(1.41%), [1,1':3',1''-terphenyl]-2'-ol (1.26%), (2,3-diphenylcyclopropyl)methylphenyl sulfoxide, trans-(1.25%), furfural(1.17%), cyclotrisiloxane, hexamethyl-(1.11%), bicyclo[2.2.1]heptan-2-one, 1,7,7-trimethyl-, (1r)-(1.1%), pentadecane, 2,6,10-trimethyl-(0.87%), etc. So the warm-compaction reed material was safe below 60°С.

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.
