Abstract

EL ACIDO SILICICO DE PRECIPITACION DE PARTICULAS FINAS CON: SUPERFICIE BET (DIN60132) ENTRE 150 Y 350 M (AL CUADRADO) /G; DENSIDAD DE APISONADO (DIN 53194) ENTRE 60 Y 120 G/L; NUMERO DBP ENTRE 3.0 Y 4.0 ML/G; DISTRIBUCION DE GROSOR DE MINIMO 70% DE 1 A 6 (MU)M PARTICULAS ESTE ACIDO SILICICO SE PUEDE PRODUCIR CALENTANDO UNA MEZCLA DE AGUA Y SILICATO SODICO EN AGITACION A UNA TEMPERATURA DE 70 A 80 (GRADOS) C, A/ADIENDO A ESTE PRINCIPIO ACIDO SULFURICO CONCENTRADO HASTA QUE ESTE NEUTRALIZADA LA MITAD DEL ALCALI PRESENTE. A CONTINUACION SE TRATA LA MEZCLA DE REACCION POR MEDIO DE UNA CIZALLA, ELEVANDO EN SU CASO LA TEMPERATURA A 86 (MAS MENOS) 5 (GRADOS) C. TRAS UN TIEMPO DE 30 A 120 MINUTOS, SE AÑADE ACIDO SULFURICO CONCENTRADO A MAYOR VELOCIDAD, HASTA QUE EL PH DE LA SUSPENSION DE ACIDO SILICICO SEA DE 3,0 A 3,5. EN SU CASO SE DILUYE LA SUSPENSION DE ACIDO SILICICO CON AGUA, A SU VEZ, SI ES NECESARIO SE SEPARA LA PARTE GRUESA POR MEDIO DE UNA BOMBA CENTRIFUGA Y DE UN HIDROCICLON; A CONTINUACION SE FILTRA EL ACIDO SILICICO CON FILTROS YA CONOCIDOS Y SE LAVA LA TORTA DE ACIDO SILICICO PARA RETIRAR EL SULFATO. SE REDISPERSA ENTONCES LA TORTA DE ACIDO SILICICO, AÑADIENDO AGUA, POR MEDIO DE UN DISPOSITIVO DE REMOVIDO PARA FORMAR UNA SUSPENSION CON UN CONTENIDO SOLIDO DE 80 (MAS MENOS) 10 G/L. A ESTA DISPERSION SE AÑADE EN SU CASO ALQUILDIMETILBENZIL- AMONIOCLORURO. LA SUSPENSION SE SECA POR PULVERIZADO Y, EN SU CASO, SE MUELE EL PRODUCTO SECO. EL ACIDO SILICICO DE PRECIPITACION SE PUEDE USAR TANTO REVESTIDO COMO SIN REVESTIR COMO MATEADOR EN LACAS.
