Abstract

Se provee una forma mejorada de carbonato de calcio que es resistente al ácido para permitir su uso como un material de relleno en la fabricación depapel de neutro hasta levemente ácido y un proceso para producir este carbonato de calcio resistente al ácido. Este carbonato de calcio resistente al ácidoestá formado por al menos alrededor de 0,1 por ciento basado en el peso seco del carbonato de calcio, de una mezcla de ácidos débiles en una mezcla con elcarbonato de calcio.An improved form of calcium carbonate is provided that is acid resistant to allow its use as a filler in neutral to slightly acidic papermaking and a process to produce this acid resistant calcium carbonate. This acid resistant calcium carbonate is made up of at least about 0.1 percent based on the dry weight of calcium carbonate, from a mixture of weak acids in a mixture with calcium carbonate.
