In this research, intermediate calamagrostis vegetal fiber (FIC) combined samples were carried out in combination with polyester resin (RP), Aluminum Hydroxide (HA) and Magnesium Hydroxide (MH). The aim of this study is to determine inorganic flame-retardant effectiveness in the intermediate calamagrostis’ combustion rate reduction from Ecuador’s moorlands and possible forest fires’ control of this endemic plant species. The flammability index was obtained following the ISO 3795 standard; In addition, the contamination degree: Carbon Monoxide (CO) was determined, following the standard EPA 40 CFR, method 60 Annex A. The composite material was evaluated in a horizontal flammability chamber. Furthermore, the experimental design considered seven tests, one control and two flame retardants’ types. Aluminium Hydroxide and Magnesium Hydroxide accounted for three different concentrations at 3%, 6% and 9% percent each one. Thus, these flame retardants’ effectiveness was greater for Aluminium Hydroxides at all the proposed concentrations, while for Magnesium Hydroxide; its effectiveness was positive for a concentration of 9% only. The study determines that the best combination of materials are: 70% FIC, 21% PR, 9% HA, resulting in a combustion rate of 190.98 mm / min and self-extinguishing capacity. Finally, an average decrease of 50% in the generation of CO and the amount of smoke was determined.

无机阻燃剂氢氧化铝、氢氧化镁对厄瓜多尔沼泽中间体 Calamagrostis 燃烧速率的影响

在本研究中,中间体 calamagrostis 植物纤维 (FIC) 组合样品与聚酯树脂 (RP)、氢氧化铝 (HA) 和氢氧化镁 (MH) 组合进行。本研究的目的是确定无机阻燃剂在厄瓜多尔高沼地的中间 calamagrostis 燃烧率降低和可能的森林火灾对这种地方植物物种的控制中的有效性。可燃性指数按照ISO 3795标准获得;此外,按照标准 EPA 40 CFR、方法 60 附件 A 确定污染程度:一氧化碳 (CO)。在水平可燃室中评估复合材料。此外,实验设计考虑了七项测试,一种对照和两种阻燃剂类型。氢氧化铝和氢氧化镁占三种不同的浓度,分别为 3%、6% 和 9%。因此,这些阻燃剂在所有建议浓度下对氢氧化铝的有效性都更高,而对氢氧化镁;其有效性仅在 9% 的浓度下为阳性。研究确定材料的最佳组合为:70% FIC、21% PR、9% HA,从而产生190.98 mm/min的燃烧速率和自熄能力。最后,确定了 CO 的产生和烟雾量平均减少了 50%。其有效性仅在 9% 的浓度下为阳性。研究确定材料的最佳组合为:70% FIC、21% PR、9% HA,从而产生190.98 mm/min的燃烧速率和自熄能力。最后,确定了 CO 的产生和烟雾量平均减少了 50%。其有效性仅在 9% 的浓度下为阳性。研究确定材料的最佳组合为:70% FIC、21% PR、9% HA,从而产生190.98 mm/min的燃烧速率和自熄能力。最后,确定了 CO 的产生和烟雾量平均减少了 50%。
