spp. particleboard with the incorporation of lignin and soy flour as binders were fabricated and the influence of different percentages of lignin and soy flour (0%, 6% and 12%) on the physico-mechanical properties of the particleboard were studied. The samples were characterised by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray fluorescence (XRF) and internal bonding. The results stipulated that the addition of binders in the fabrication of the particleboard did not change the functional groups according to the FTIR spectrum. For XRD, addition of binders did not reveal any major transformation within the composites. SEM and EDX analyses for all percentages of binders added showed no apparent disparity; however, it is important to note that the incorporation of binders allows better bonding between the molecules. In XRF analysis, lower percentage of chlorine in the adhesive-bonded samples may be advantageous in maintaining the natural properties of the particleboard. In internal bonding, increased internal bond strength in samples with binders may indicate better structural integrity and physico-mechanical strength. In conclusion, the incorporation of lignin and soy flour as binders may potentially strengthen and fortify the particleboard, thus, can be a reliable phantom in radiation dosimetry applications.
制备了添加木质素和大豆粉作为粘合剂的刨花板,并研究了不同比例(0%、6%和12%)的木质素和大豆粉对刨花板物理力学性能的影响。通过傅里叶变换红外光谱(FTIR)、X射线衍射(XRD)、扫描电子显微镜(SEM)、能量色散X射线(EDX)、X射线荧光(XRF)和内结合强度对样品进行了表征。结果表明,根据FTIR光谱,在刨花板制造过程中添加粘合剂不会改变官能团。对于XRD,添加粘合剂在复合材料中未显示任何重大转变。对所有添加粘合剂比例的SEM和EDX分析均未显示明显差异;然而,需要注意的是,添加粘合剂可使分子间更好地结合。在XRF分析中,粘合剂粘结样品中较低的氯含量可能有利于保持刨花板的天然性能。在内结合强度方面,含粘合剂样品的内结合强度增加可能表明结构完整性和物理力学强度更好。总之,添加木质素和大豆粉作为粘合剂可能会增强和加固刨花板,因此,在辐射剂量学应用中可以成为一种可靠模体。
