Abstract
Los soportes para almacenamiento de colecciones de historia natural realizados con materiales como la madera, la resina, el papel, el cartón o el algodón pueden generar acidificación; sin olvidar las eventuales complicaciones que podrían derivarse del carácter polimatérico de los ejemplares, tanto por su naturaleza como por los materiales utilizados para su realización. Por tanto, al hablar de deterioro y acidificación, se deben contemplar los factores intrínsecos y extrínsecos. De este modo, contaminantes externos como el dióxido de azufre (SO2), óxidos de nitrógeno (NOx), ozono (O3) o sulfuro de hidrógeno (H2S), pueden interactuar con los contaminantes ácidos producidos por materiales dentro de los propios almacenes como el ácido acético (CH3COOH) y el ácido fórmico (HCOOH), donde la humedad relativa y la temperatura favorecen o evitan una determinada reacción. En este contexto, el algodón y la paja han tenido un protagonismo indiscutible en soportes y relleno en taxidermia artística y científica. Aquí presentamos como alternativa de relleno una poliamida empleada en otros contextos: el Perlón®.
: Storage supports for natural history collections made with materials such as wood, resin, paper, cardboard or cotton, they can generate acidification; without forgetting the effects that the polymeric nature of the specimens can produce, both due to their nature and the materials used to produce them. Therefore, intrinsic and extrinsic factors must be considered when speaking of deterioration and acidification. In this way, external pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), ozone (O3) or hydrogen sulfide (H2S), can interact with acidic pollutants produced by materials within their own warehouses such as acetic acid (CH3COOH) and formic acid (HCOOH), where relative humidity and temperature favor or avoid a certain reaction. In this context, cotton and straw have had an indisputable role in supports and fillers in artistic and scientific taxidermy. Here we present as a filling alternative a polyamide used in other contexts: Perlon®.
