Abstract
Bentonita sódica aditivada para el uso en la composición de arena verde para el moldeo de partes de vaciado se relaciona a una composición de bentonita sódica aditivada a través de la adición de dextrina y azúcar o almidón y azúcar en cantidades específicas durante el proceso de activación de bentonita cálcica por medio de la incorporación de carbonato de sodio en la mena "en la naturaleza", que pertenece al campo de la industria química para el uso en la composición de arena verde para el moldeo de vaciados, que ofrece una amplia gama de ventajas en comparación con las fórmulas existentes.
