迷彩刨花板的研制及力学性能分析

目的研究不同色彩处理方式对大片刨花表面相对自由基浓度的影响,及不同迷彩组合色对板材力学性能的影响。方法通过对大片刨花进行煮沸染色,采用电子自旋共振波谱仪对各类处理方式刨花检测其相对自由基浓度,然后根据不同迷彩色方案进行压制板材,采用万能力学电子实验仪检测其力学性能,分析不同迷彩刨花板的相对自由基浓度与力学性能的关系。结果刨花的不同处理方式(煮沸与否、染色与否、染料种类、染料浓度等)对其相对自由基浓度影响方差分析F值为119.4;5类不同色刨花板的力学性能MOR方差值为9.38;丛林迷彩板材力学强度最高,弹性模量为5883.47 MPa,结合强度为0.68 MPa,静曲强度为52.37 MPa。结论各迷彩色酸性染料染色处理对刨花表面的相对自由基浓度有显著影响,有益于板材的胶合性能;4种常见迷彩配色方案中,板材的力学性能也有所提升,尤其是丛林迷彩板材具备较优的力学性能。

Development of Camouflage Particle Board and Analysis of Its Mechanical Properties

This work aimed to study the effects of different color treatments on the relative free radicals concentration of boiling dyeing flake surface, and the effects of different camouflage color combinations on the mechanical properties of the board. During the boiling dyeing of flakes, the relative free radicals of flakes which were differently treated were detected by the electron spin resonance spectrometer. Then different plates were pressed by different camouflage color schemes. Their mechanical properties were detected by universal mechanical electronic experiment instrument. And the relationship between the relative free radicals concentration and the mechanical properties of different Camouflage Particle boards was analyzed in this paper. The F value of variance of different treatments (boiled or not, dyed or not, the type of dye, the concentration of dye, etc.) was 119.4. The MOR variance of the mechanical properties of five different Camouflage Particle boards was 9.38. Jungle camouflage plates had the best mechanical properties, with parameters of MOE(5883.47 MPa), IB(0.68 MPa), MOR(52.37 MPa). Different dyeing treatments of acid dyes had significant influence on the relative free radicals concentration, and they were beneficial to the bonding strength of plate. The mechanical properties of plate were also improved by the four common camouflage color schemes. Especially, jungle camouflage plates had relatively good mechanical properties.
