Abstract

MÉTODOS E SISTEMAS PARA ACRESCENTAR UM ADITIVO DE GESSO DE ALTA VISCOSIDADE A UMA DISPERSçO AQUOSA PàS-MISTURADOR DE GESSO CALCINADO. São providos métodos e sistemas para introdução de um acelerador de gesso úmido ou outro aditivo de produção de alta viscosidade a uma dispersão aquosa de gesso calcinado em um aparelho de descarga a jusante de um misturador de estuque onde a dispersão foi preparada. Esses métodos e sistemas são úteis na produção de vários produtos de gesso, tais como, painel, incluindo painel de parede e placas para teto.METHODS AND SYSTEMS FOR ADDING A HIGH VISCOSITY PLASTER ADDITIVE TO A WATER DISPOSAL OF CALCINED PLASTER MIXER. Methods and systems are provided for introducing a wet plaster accelerator or other high viscosity production additive to an aqueous dispersion of calcined plaster in a downstream discharge apparatus of a stucco mixer where the dispersion was prepared. These methods and systems are useful in producing various plaster products, such as panel, including wall panel and ceiling boards.
