Abstract

ESTA INVENCION SE REFIERE A UNOS BORDES CORTANTES DE UNA CUCHILLA DE UNA MAQUINILLA DE AFEITAR QUE PRESENTAN UNA MEJORA EN EL PRIMER AFEITADO. LOS BORDES CORTANTES DE UNA CUCHILLA DE UNA MAQUINILLA DE AFEITAR CONVENCIONAL PRESENTAN UNA FUERZA DE CORTE INICIAL SORPRENDENTEMENTE ELEVADA. LAS CUCHILLAS DE MAQUINILLA DE AFEITAR FABRICADAS SEGUN EL PRESENTE PROCEDIMIENTO PRESENTAN UNA FUERZA INICIAL SIGNIFICATIVAMENTE INFERIOR, LO QUE SE TRADUCE POR UN PRIMER AFEITADO MAS CONFORTABLE. UNAS HOJAS MEJORADAS SEGUN LA PRESENTE INVENCION IMPLICAN UN TRATAMIENTO DE BORDES DE HOJA DE AFEITAR CONVENCIONAL QUE TIENEN UN REVESTIMIENTO ADHERENTE DE POLIFLUOROCARBONO, CON UN DISOLVENTE PARA RETIRAR PARCIALMENTE UNA PARTE DE ESTE REVESTIMIENTO. LOS DISOLVENTES PREFERIDOS INCLUYEN PERFLUOROALCANOS, TENIENDO LOS PERFLUOROCICLOALCANOS Y PERFLUOROPOLIETERES UNA TEMPERATURA CRITICA O UN PUNTO DE EBULLICION SUPERIOR A LA TEMPERATURA DE DISOLUCION DEL POLIFLUOROCARBONO EN EL DISOLVENTE. LA PRESENTE INVENCION SE REFIERE TAMBIEN A UN PROCEDIMIENTO DE PRODUCCION DE ESTOS BORDES CORTANTES DE HOJAS DE AFEITAR.
