Abstract

Se refiere a una lechada de yeso que incluye agua, un componente hidraulico que incluye sulfato de calcio hemihidrato y un dispersante de policarboxilato lineal. El dispersante anionico de policarboxilato lineal incluye una primera unidad repetitiva monomerica y una segunda unidad repetitiva monomerica. La primera unidad repetitiva del dispersante de policarboxilato lineal es una unidad repetitiva de acido carboxilico insaturado olefinico o una sal de esta. La segunda unidad repetitiva del dispersante de policarboxilato lineal es un sulfonato de vinilo. La lechada se puede convertir en un panel de yeso. Tambien se describen metodos para producir lechada de yeso y un panel de yeso.
