Abstract

Se elabora una lechada que incluye agua, al menos 50% en peso de hemihidrato de sulfato de calcio, y un dispersante de policarboxilato específico que se preparar utilizando al menos tres unidades repetitivas. Una primera unidad repetitiva es una unidad repetitiva de tipo éter vinílico que incluye una unidad repetitiva de tipo ácido maleico. Una tercera unidad repetitiva incluye una unidad repetitiva de tipo ácido acrílico. El dispersante de polímero tiene un peso molecular que está entre aproximadamente 20.000 y 80.000Daltons. La lechada elaborada a partir de esta composicion puede elaborarse a niveles de agua reducidos para secar a velocidad y reducir los costos de secado.
