Particleboard as an interior decoration materials, processing and use of the process will release formaldehyde and other aldehydes, alkanes, terpenes, aromatic hydrocarbons and other volatile compounds, indoor environment and the human body to cause some harm. Thesis poplar particleboard study different decorative materials control of the particleboard volatile organic compounds and formaldehyde release key research veneer particleboard different hot-pressing process conditions VOCs release of ingredients, the release of Law and Influence Factors evaluated veneer particleboard VOCs released in the aging process, and provide the basic data for the effective and reasonable control particleboard VOCs emissions. Finally, to predict the release of VOCs. The conclusions are as follows: a different decorative materials to the the particleboard substrate of VOCs to be effectively controlled. Wherein polypropylene paste surface control effect best, the particleboard release TVOC and formaldehyde highest concentration, followed melamine impregnated paper, veneer, waterborne coatings ineffective control TVOC concentrations. 2 decorated before Aspen particleboard measured 21 release component, the main component of the phthalic acid (2 - ethyl hexyl) ester; veneer Aspen particleboard measured 16 kinds of ingredient-release, in front of the relative content ratio decorated relative content is low. 3 visits sizing ratio, pressing, pressing temperature and resin content of the three levels of the four factors optimal process experiments. Veneer particleboard VOCs emission least, the best hot-pressing process conditions: sizing ratio of 60:40, the glue content 100g/m2, hot pressing time 3min, hot pressing temperature 100 ° C. 4 sizing ratio, the amount of sizing, pressing temperature and veneer species for single-factor experiments investigated the factor, the results show that the hot-pressing temperature increases, sizing increase in volume Metropolitan veneer particleboard TVOC emission increase, The initial release concentration rise sizing ratio TVOC first decreases and then increases trend. Finishes the particleboard release of five pairs of different hot-pressing process under the conditions of the analysis of VOCs, the results show that the change of the hot pressing temperature and pressing time to make particleboard of VOCs species also changed, mainly to glue content point of view, sizing increase , alkanes volatile content increases, an increase in the aromatic compound, and terpenes and particleboard volatile matter content decreased; sintering temperature of the gas chromatography results showed that, pressing temperature rise, alkanes and terpene the relative content of the substances is less, the greater the relative content of aromatic compounds; release of VOCs veneer species Experimental pine veneer panels up and found that the α-pinene and other alkanes, and in addition to esters material, the relative content of the release of the ingredients of pine plywood, black walnut release substances, at least relative content. 6 veneer the particleboard release monomer attenuation detection by emission inventory analysis results show that the release of monomers is gradually reduced with time in the number of veneer particleboard; alkane monomers decreases as time increases the relative content . Terpenes initial release of the relatively low levels, the relative content increases as the time increases, the terpenes, but little change in the relative content of aromatic substances.
