| 摘 要： | 为研究阻燃剂粉尘可爆性，依据不同实验标准所采用的哈特曼管和20 L球爆炸实验系统，对几种常见阻燃剂粉尘可爆性进行了初步研究。结果表明:按不同标准实验，四溴双酚A、三聚氰胺、二乙基次膦酸铝、赤磷和对二丁基氧化锡均为可爆性粉尘；三氧化二锑、钛白粉、碳酸钙、氢氧化铝和二氧化硅均为不可爆性粉尘；氰尿酸三聚氰胺、球形硅树脂粉以及膨胀石墨的粉尘可爆性结果不一致。对于某些阻燃剂，点火源的起始能量对粉尘可爆性结果有较大影响；某些阻燃剂对爆炸具有抑制效应，抑制程度同物质本身的性质和浓度有关系。

| Abstract: | To study the explosibility of flame retardant dust, the preliminary study on the explosibility of several common flame retardants dust was carried out according to the Hartmann tube and 20 L sphere explosion test system adopted in different test standards. The results showed that according to different test standards, the tetrabromobisphenol A, melamine, aluminum phosphinate, red phosphorus and dibutyltin oxide were all the explosibility dust, and the diantimony trioxide, titanium dioxide, calcium carbonate, aluminium hydroxide and silicon dioxide were all the non-explosibility dust, while the melamine cyanurate, spheric microparticles of silicone resin and expanded graphite had the inconsistent results of dust explosibility. The initial energy of ignition source had a greater influence on the results of dust explosibility for some flame retardants. Some flame retardants had the suppression effect on the explosion, and the suppression degree was related to the properties and concentration of the material itself. |
