En pl\u00e1sticos, goma, adhesivos y otros materiales polim\u00e9ricos y compuestos, los rellenos de polvo no met\u00e1lico, tales como el carbonato de calcio, el caol\u00edn, el talco, el cuarzo, la wollastonita, el amianto, el hidr\u00f3xido de magnesio, el hidr\u00f3xido de aluminio, etc., deben modificarse en la superficie del relleno para mejorar su compatibilidad con la matriz, su dispersi\u00f3n, su resistencia mec\u00e1nica y su rendimiento general.<\/p>\n

La modificaci\u00f3n superficial es uno de los medios de procesamiento necesarios para que el relleno pase de tener un papel incremental com\u00fan y corriente a desempe\u00f1ar un papel funcional, y es adem\u00e1s el prop\u00f3sito principal para modificar la superficie de los rellenos minerales.<\/p>\n

Siempre que se satisfagan las condiciones de proceso y del mecanismo de modificaci\u00f3n, un buen m\u00e9todo para completar la modificaci\u00f3n con un alto nivel de activaci\u00f3n de materiales con forma irregular como escamas y agujas, as\u00ed como materiales ultraligeros, ultrafinos, viscosos y aglomerados consiste en usar molinos de alta potencia durante la molienda.[\/vc_column_text][\/vc_column][vc_column column_width_percent=\u00bb100″ gutter_size=\u00bb3″ back_image=\u00bb86100″ overlay_alpha=\u00bb50″ shift_x=\u00bb0″ shift_y=\u00bb0″
