【摘要】：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-方文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。
[Abstract]:In this paper, the changes of quality and wet buffer value of three kinds of bamboo silk decorative materials in the cycle of absorption-desiccating cycle in high humidity area were studied, which were untreated and treated by flame-retardant and anti-mildew and flame-retardant treatment. The morphology and relative crystallinity of bamboo decorative materials were characterized by ESEM and X- ray diffractometer. The results show that the three kinds of bamboo decorative materials have a certain moisture buffering property, and the results show that the three kinds of bamboo silk decorative materials have a certain moisture buffering property, and the results show that the three kinds of bamboo silk decorative materials have a certain moisture buffering property. During the period of hygroscopic-#china_person0# wet cycle, the mass change showed a step by step trend. The wet buffering performance of each treatment group was as follows: the flame retardant treatment group (MBV), the untreated group (C), the anti-mildew and flame-retardant treatment group (NP4), the same group as the near green layer bamboo silk decoration material, the near yellowish layer bamboo silk decoration material, which followed the law of MBV moisture absorption and MBV dehumidification during the moisture absorption and desiccation cycle. ESEM and XRD analysis showed that there was good deposition in parenchyma cells, but there was no effect on moisture flow during hygroscopic and dehumidification. The relative crystallinity of cellulose decreased slightly after flame retardant treatment.
