Presentaci\u00f3n de la norma ASTM D3258: Industrial Physics<\/h2>\n

ASTM D3258 es un m\u00e9todo normalizado internacional ASTM para determinar la porosidad de alcoholes minerales blancos o casi blancos en pel\u00edculas de pintura insolubles. Este m\u00e9todo de ensayo ASTM lo consigue manchando para indicar el grado de penetraci\u00f3n de una capa posterior.<\/p>\n

El proceso de prueba ASTM D3258<\/h2>\n

Para realizar la prueba ASTM D3258 necesitar\u00e1s aplicadores de pel\u00edcula, un reflect\u00f3metro, una placa de vac\u00edo, un cepillo de pelo de camello, una botella de lavado de pl\u00e1stico, un panel de prueba, un medio penetrante y papel de filtro.<\/p>\n

Seg\u00fan este m\u00e9todo ASTM, la pintura de prueba se aplica a una superficie no porosa, se seca al aire y, a continuaci\u00f3n, se mide la reflectancia. Se aplica un medio penetrante de color especial, se elimina el exceso de una manera espec\u00edfica y se mide nuevamente la reflectancia. La diferencia entre las dos lecturas indica el grado de porosidad; cuanto menor sea la diferencia, menor ser\u00e1 la porosidad de la pel\u00edcula y mayor su capacidad para resistir la penetraci\u00f3n.<\/p>\n

Entonces, \u00bfc\u00f3mo puede Industrial Physics mejorar sus pruebas ASTM D3258?<\/p>\n

Aplicadores de pel\u00edcula de una sola abertura, tipo bird<\/strong><\/a><\/p>\n

El aplicador de pel\u00edcula tipo TQC Sheen bird tiene un borde plano y est\u00e1 dise\u00f1ado para soportar pruebas seg\u00fan las normas, incluida la ASTM D3258. Es una gran elecci\u00f3n para los laboratorios de revestimientos y las empresas dedicadas a la producci\u00f3n de pinturas.<\/p>\n

El aplicador de ranura \u00fanica ‘bird-type’ est\u00e1 disponible en dos tama\u00f1os diferentes y es adecuado para aplicar una serie de revestimientos sobre sustratos planos y relativamente s\u00f3lidos. Es un aparato robusto y el acero inoxidable de alta calidad no se ve afectado por los elementos \u00e1cidos o b\u00e1sicos.<\/p>\n
