Abstract

PRODUTOS DE GESSO DE SECAGEM RAPIDA. Uma mistura semifluida é produzida incluindo água, pelo menos 50% em peso de hemihidrato de sulfato de cálcio e um dispersante de policarboxilato específico, preparado utilizando-se pelo menos três unidades de repetição. Uma primeira unidade de repetição é uma unidade de repetição do tipo vinil éter. Uma segunda unidade de repetição é uma unidade de repetição do tipo ácido maleico. Uma terceira unidade de repetição inclui uma unidade de repetição do tipo ácido acrílico. O dispersante polimérico possui um peso molecular de cerca de 20.000 a cerca de 80.000 Dalton. A mistura semifluida produzida a partir desta composição pode ser produzida em níveis de água reduzidos para acelerar a secagem e reduzir os custos de secagem.
