Flammability properties of fire-retardant timber

Introduction. At present, the house-building industry, that produces timber structures, is in process of sufficiently intensive development; however, high flammability wood factor restrains widespread use construction. The purpose this work to optimize conditions application fire-retardant construction industry. co-authors believe following problems are be solved attain objective:● a comparative analysis fireproofing efficiency several fire-proofing agents applied different species wood;● determination character influence produced by fire proofing on retardant properties wood. Methods research. sample compositions designated for was measured compliance with benchmark testing method specified GOST R 53292 (p. 6.2). Experiments were launched pursuant methodology and help measurement instruments 30244–94 (Method 2) study extent pine-tree suppression. Critical values thermal loads may trigger inflammation flame propagation can described using critical surface density heat flow, determined 30402–96 51032–97. toxicity combustion products smoke generation ability samples assessed standard methods 12.1.044–89 (paragraphs 4.18 4.20). Research results discussion. Biological retardants, integrated biological retardants also ensure moisture protection, intumescent coatings, lacquers varnishes ready labelled as having group I II 53292, studied course research project. have identified mass loss all below 9 %, if larch oak-tree timber, same it timber.The findings experiment conducted assess flammability, ignitibility, propagation, proven maximal composition full-cell pressure impregnation ensures material G1, V1, RP1, T2, D2. Conclusions. Hence, enabled discrepancy between average demonstrated (alder, linden, pine-tree, larch, oak-tree).The comprehensive treated vary their chemical mode action agent, identify impact versatile regard taken fire-safe materials constructions buildings structures.
