竹丝装饰材的湿缓冲特性研究
对未处理和经过阻燃处理、防霉阻燃处理的三种竹丝装饰材在高湿地区吸-放湿循环周期内质量的变化规律和
湿缓冲值(MBV)进行了研究;利用环境扫描电镜(ESEM)和X-射线衍射仪(XRD)对竹丝装饰材料在磷酸脒基脲阻燃剂处
理前后的微观形貌和相对结晶度进行了表征;并以实例量化三种竹丝装饰材料对室内环境的吸-放湿变化量。研究结果
表明:三种竹丝装饰材均具有一定的湿缓冲性能,在吸湿-放湿循环周期内质量变化呈周期性阶梯状上升趋势,各处理组
间湿缓冲性能表现为阻燃处理组(NP)>未处理组(C)>防霉阻燃处理组(NP4),同组表现为近青层竹丝装饰材(OB)>
近黄层竹丝装饰材(IB),吸放湿周期内遵循MBV吸湿>MBV放湿的规律,其中阻燃处理近青层竹丝装饰材( OB) 湿度调节能
力最佳;通过ESEM和XRD分析发现:磷酸脒基脲在薄壁细胞中有较好的沉积,但对吸湿-放湿中的水分流动不造成影响,
阻燃处理后竹丝装饰材的纤维素相对结晶度略有降低。

Research on the Moisture Buffering Properties of Decorative Bamboo Filament
Research was carried on to evaluate the quality change rule and Moisture Buffering Value(MBV)#br# within moisture absorption and releasing cycle period in high humidity environment for three kinds of decorative#br# bamboo filament(untreated, fire retardant treatment and anti-mold fire retardant treatment). The environment#br# scanning electron microscopy (ESEM)and X- ray diffraction (XRD) were used as characterization methods to#br# research microtopography and relative crystallinity before and after fire retarding treatment with guanylurea#br# phosphate. Results showed that three kinds of decorative bamboo filaments all had the ability of humidity control,#br# the quality change appeared step-like rising trend, furthermore, the order of moisture buffering performance for#br# different treatment group respectively was NP>C>NP4,OB>IB in the same treatment and MBVabsorption>MBVrelease#br# in the test cycle, the humidity adjustment of OB was the best. The XRD and SEM respectively indicated that#br# guanylurea phosphate had better sedimentary in parenchymal cell, but had no effect on moisture flow during#br# moisture absorption and releasing, decorative bamboo filament had a slight decrease of relative crystallinity after#br# flame retardant treatment.
