Abstract

"PLACA DE GESSO LEVE E MéTODO DE FABRICAçãO". Um produto de placa de gesso leve pode ser produzido modificando-se o gesso calcinado antes de ele ser introduzido em uma pasta fluida de gesso e antes da introdução de um agente espumante pelo uso de um gerador de espuma e pressão de ar elevada. O agente espumante tem tamanho e distribuição de bolhas uniformes e estáveis. A espuma confere estas propriedades de vazios vantajosas e resulta em um produto de gesso leve que tem características de resistência e extração adequadas.
