Abstract

LA INVENCION SE REFIERE A UNA BOQUILLA ELECTROSTATICA PARA LA FABRICACION DE PLANTILLAS DE ESTAMPADO, LAS CUALES SE EMPLEAN, EN PARTICULAR, EN EL CAMPO DE LA INDUSTRIA TEXTIL. ESTAS PLANTILLAS DE ESTAMPADO SE COMPONEN DE UN TAMIZ DE MALLA FINA (1), QUE SOPORTA UN MODELO. EL MODELO SE PRODUCE PORQUE UN LIQUIDO DE CUBRICION VISCOSO CON AYUDA DE LA BOQUILLA ELECTROSTATICA SOLO SE APLICA EN AQUELLOS LUGARES SOBRE EL TAMIZ (1), EN EL CUAL EL TAMIZ (1) SE DEBE CUBRIR DE ACUERDO CON EL MODELO Y QUEDAN SIN CUBRIR AQUELLOS LUGARES DEL TAMIZ (1) EN LOS CUALES ESTE DEBE PERMANECER PERMEABLE. PARA PODER PULVERIZAR EL LIQUIDO DE CUBRICION VISCOSO, PENETRA EN UN CANAL DE PULVERIZACION (30) DE LA BOQUILLA (2) UNA AGUJA (31), QUE SE EXCITA A VIBRACION DE ALTA FRECUENCIA. DE LAS FUERTES PERTURBACIONES ASI CAUSADAS RESULTAN MARCADOS ESTRECHAMIENTOS REGULARES CORRESPONDIENTES A LA FRECUENCIA DE LA VIBRACION DEL CHORRO DE LIQUIDO QUE ABANDONA EL CANAL DE PULVERIZACION, DE MODO QUE FUERA DEL CANAL DE PULVERIZACION A CONSECUENCIA DE LA TENSION SUPERFICIAL DEL LIQUIDO SE PUEDEN FORMAR GOTAS MUY RAPIDAMENTE. ESTO CONDUCE A UNA LONGITUD DE CONSTRUCCION CORTA DE LA BOQUILLA.
