Ventajas Advantages
Esta invención proporciona las siguientes ventajas a quien lo utilice: This invention provides the following advantages to anyone who uses it:
1.- Al aplicar este proceso, la metálica lámina queda con un terminado poroso y en relieve, y si se aplica pintura se adhiera de manera que no se cae y aun mejor si se hornea.
2.- Con este proceso ya es posible que ahora los anuncios comerciales se puedan fabricar en lámina de acero inoxidable, y por lo tanto ya no se oxidarla tan rápido, como con la lámina de hierro. 1.- When applying this process, the metallic sheet is left with a porous and embossed finish, and if paint is applied it adheres so that it does not fall off and even better if it is baked. 2.- With this process it is possible that now the commercials can be manufactured in stainless steel sheet, and therefore it will no longer oxidize as quickly, as with the iron sheet.
3.- Con este proceso el producto resultante es de mayor calidad, porque no se cae la pintura ni se raya fácilmente, es económico y fácil de aplicarse. 3.- With this process the resulting product is of higher quality, because the paint does not fall off or scratch easily, it is economical and easy to apply.
La presente invención soluciona los siguientes inconvenientes a) Que la lámina de fierro no se oxide, logrando con esto una estética en el logotipo o dibujo, es decir la imagen con mayor claridad, color y relieve. b) Que la lámina de acero inoxidable que no se podía pintar o decorar ya que no cuenta con porosidad (anclaje) , ahora por este proceso si es posible lograr este efecto o acabado en color. c) Que al ponerle al acero inoxidable logotipos, decoración, rótulos etc., jamás se le caerá porque la pintura queda perfectamente adherida y si se hornea durará más tiempo y no se rayara fácilmente.
Ejemplos The present invention solves the following drawbacks a) That the iron sheet does not rust, thereby achieving an aesthetic in the logo or drawing, that is, the image with greater clarity, color and relief. b) That the stainless steel sheet that could not be painted or decorated since it does not have porosity (anchoring), now by this process if it is possible to achieve this effect or finish in color. c) That when putting stainless steel logos, decoration, labels etc., it will never fall out because the paint is perfectly adhered and if it is baked it will last longer and will not scratch easily.
