The New Progressive Polymeric Materials for the Reduction of VOC in the Woodworking Industry

Abstract

The paper deals with the preparation of new type of progressive polymer blends created from bicomponent synthetic fibres (PP/PA6) with addition of interfacial agent maleine-anhydrid (MAH) and polymeric mixtures with varying content of the polyamide component for the purpose of subsequent production of a highly efficient filters for collection of hazardous chemical (VOC) in processes surface finishing and treatment of wood products. Morphological parameters were studied in relation to the supramolecular structure of the mechanical properties and the specific rheological characteristics in terms of their experimental process of spinning of bicomponent fibres.

Ultimate and Elemental Analysis of Some Common Charcoal in Southwestern Nigeria

“…Sulphur in the burning process is converted to sulfur oxides which are pollutant to the environment and also be irritating to the human respiratory system. ( [23,24,25]). The Sulphur content ranges from 0.00% for Burkea africana (Asapa), Funtumia elastica (Ire) and Milletia thonningii (Ito) to 1.03% for Hevea brasilensis (Rubber).…”

The Evaluation of Specific Environmental and Degradation Characteristics of Surface Treated Wood

“…The results of quantitative content present dangerous chemicals (selected from the VOC) produced during thermal loading of surface treated wood coating system Chemolak are shown in Table 3. It was found that the thermal degradation of cross-linked thermosetting polyurethane coatings PUR decomposition to toxic isocyanates, which are further degraded to benzene and carbon monooxide (CO -combustible toxic gass) [3]. PUR binder of emitted solvents: toluene, xylene and formaldehyde.…”

“…Solvent-based coatings are sources of volatile organic compounds (VOC) emissions that cause serious health problems (carcinogenic, harmful, irritant effects) [2]. The production of these dangerous chemicals takes place in the processes applied to the wood surface [3]. To release emissions may occur when burning wood with applied solvent based polyurethanes, which are frequently used in the finalization of wood products.…”

“…In the process of burning and thermal decomposition will evolve from the polyurethane coatings toxic compounds, e.g. isocyanates, benzene and other flammable and hazardous gases (mainly CO) [3,5].…”

“…Standard evaluated criteria for surface treatment of wood shall include an assessment of defects formed coatings, further evaluation for physical, chemical, mechanical, thermodynamical and specific properties [3,4]. To assess the fire safety properties of wood products, it is important to know the effect of surface treatment to change the quality of these products.…”
