Definitions

  • the invention refers to a treatment method of granite slabs by means of a laser radiation application, permitting the superficial modification of granite slabs for using in both facades and floorings, obtaining a bushhammered-type surfacing, in other words a surface with a rough surfacing giving the impression of being more rustic and natural.
  • granite has been used for a long time in constructing large public works, buildings, etc., although granite is currently widely used as a decorative element, in other words as a facade siding of large buildings and as both indoor and urban flooring.
  • the alternative to buffed granite is the bushhammered or flamed surfacing since the sawn surfacing is too rough for some applications.
  • the bushhammered granite can successfully be applied to practically all granite varieties and it gives the stone a more rustic and natural surfacing.
  • Flaming consists of a thermal treatment of the surface by means of oxyacetylene burners applied at a 45o inclination with the surface and an approximate flame temperature of 2,800o C.
  • the drawbacks of flaming are the following:
  • the proposed method has been conceived to solve the previously explained drawbacks, being based on a simple yet no less efficient solution, since it is the laser application for treating a natural rock such as granite.
  • granite encompasses not only the rocks geologically considered granites (Rosa Porri o, sylvan varieties), but also others such as gneisses (Rojo Guadajira), gabbros (Negro Villar), diorites (Gris Mondariz, Negro Badajoz) etc..., until reaching more than 80 exploited varieties in Spain alone.
  • the treatment method of the invention basically consists of the following:
  • the basic required condition is that the density of power reached on the granite piece be enough, which is why the most suitable lasers are those from CO 2 , CO, Nd:YAG or diode.
  • the bushhammering or the thus called treatment is carried out by moving either the granite slab or piece against the laser beam or the laser beam in relation to the granite slab or piece, such that, due to the large mass of the commercial granite boards, it is preferable to move the laser beam, the slab remaining stationary, for the purpose of the laser beam sweeping the surface of the granite slab or piece in those areas in which a transformation of the surface condition is desired to be obtained.
  • the laser incidence to the surface of the granite slab can be normal or form a certain angle with it, such that by varying this angle, the type of surfacing can be modified, it even being possible to carry out a continuous modification of that incidence angle, obtaining a surfacing different from the one obtained by maintaining the fixed beam orientation.
  • Said method involves a considerable improvement in the work conditions of the operator processing the granite slabs, greatly eliminating the acoustic and environmental contaminants suffered during the traditional granite slab bushhammering methods.
