Granulometric study of form and size of the particles of black re-granulated of cork residuals and low quality cork, have a great interest because it influences the proportion of resin and necessary cork for the formation of bound black regranulates by means of the use of natural resin/subresin as of different synthetic resins and in their application in projection teams of commercial particles for the formation of uniform films with a more economic cost.
In accordance with the results obtained in this and another works, it is recommended like good values of the particles a half size among (1-2,5 mm), since minimizes the effect it bounces and the quantity of resin so much natural as synthetic what allows a degree of good compacting. Everything it, supposes to improve the industrial applications and to optimize the use of commercial teams of projection of cork particles to obtain uniform movies in surfaces (insulating thermal or acoustic).
El estudio granulométrico de la forma y tamaño de las partículas de regranulados negros de residuos de corcho y corcho de baja calidad tiene un gran interés, ya que condiciona la proporción de resina/corcho necesaria para la formación de regranulados negros ligados mediante la resina natural del corcho (suberina), o con diferentes resinas sintéticas. Por ello resulta de gran importancia su aplicación a equipos comerciales de proyección de partículas, sobre superficies, para la formación de películas uniformes con un costo más económico.
De acuerdo con los resultados obtenidos en varios trabajos para este tipo de material, resulta de gran interés realizar una buena elección de la forma y tamaño de partícula (1-2,5 mm), lo que da lugar a comportamientos que permiten minimizar el efecto rebote de las partículas durante la proyección, así como reducir la cantidad de resina natural o sintética utilizada. Todo ello supone mejorar las aplicaciones industriales y optimizar el uso de equipos comerciales de proyección de partículas para obtener películas uniformes en superficies, que en el caso del corcho se aplican como aislantes térmicos o acústicos.
