Eficacia de ignífugos inorgánicos (hidróxido de aluminio, hidróxido de magnesio) en la velocidad de combustión de calamagrostis intermedia de páramos de Ecuador

Abstract

In the investigation, combined test pieces of vegetable fiber (calamagrostis intermedia) plus inorganic flame retardants (Aluminum Hydroxide and Magnesium Hydroxide) were carried out with the purpose of determining its effectiveness by means of the combustion rate of calamagrostis intermedia of paramos of Ecuador, from the ISO 3795 standard, the flammability index was obtained; In addition, the degree of contamination in parts per million was determined, for which a test was generated that allowed obtaining data that demonstrated the presence of carbon monoxide at the time of combustion. The material was evaluated in the horizontal flammability chamber of the Faculty of Mechanical Engineering of the Technical University of Ambato, then seven tests were carried out, one control and two types of fire retardants (Aluminum Hydroxide and Magnesium Hydroxide), each with 3 different concentrations at three, six and nine percent. A distance vs. time correlation was calculated, where the flammability index was determined, and by means of a statistical analysis, it was verified that the addition of fire retardants influences the combustion rate of Calamagrostis intermedia from paramos of Ecuador. The effectiveness of these fire retardants was greater for Aluminum Hydroxides at all the proposed concentrations, while for Magnesium Hydroxide the effectiveness of this was positive only for a concentration of nine percent. Finally, from the results obtained, the compliance of the combustion rate (millimeter per minute) was verified, complying with the indicators, in accordance with Ecuador's environmental standards.
