Abstract

METODO DE PREPARACION DE UN SUSTRATO DE VIDRIO. SE SELECCIONA UN SUSTRATO DE VIDRIO (13) QUE TENGA UNA SUPERFICIE ANULAR PLANA SUSTANCIALMENTE EXENTA DE PICADURAS Y ARAÑAZOS. SE DISTRIBUYE UNA SUSTANCIA FAVORECEDORA DE LA ADHERENCIA, TAL COMO CLORURO ESTANNOSO, SOBRE LA SUPERFICIE DEL SUSTRATO, MIENTRAS ESTA ESTA GIRANDO. SE LAVA DICHA SUPERFICIE CON AGUA, MIENTRAS EL SUSTRATO (13) ESTA GIRANDO, PARA QUITAR LOS RESTOS DE LA SUSTANCIA FAVORECEDORA DE LA ADHERENCIA. SE HACE GIRAR EL SUSTRATO A UNA ELEVADA VELOCIDAD COMPRENDIDA ENTRE 750 Y 1000 RPM., AL OBJETO DE SECAR SU SUPERFICIE. POR ULTIMO, SE DISTRIBUYE A TRAVES DE UN TUBO (41) UNA SOLUCION DE FOTO-RESERVA DILUIDA SOBRE LA SUPERFICIE SECA DEL SUSTRATO.
