A new cleaner process to prepare pressing-powder
Sociedad Española de Cerámica y Vidrio (2011)An alternative cleaner process of pressing-powder preparation, based on filter-pressing and a novel granulation method, is presented to substitute the existing spray-drying process. In the new process, about two-thirds of ... -
Análise e medida de fatores que afetam as curvaturas retardadas em porcelanato
Associação Brasileira de Cerâmic (2008)Os revestimentos cerâmicos de porcelanato, tanto os esmaltados como os não esmaltados, apresentam um fenômeno conhecido como “curvaturas retardadas”, que consiste na mudança de curvatura das peças depois da saída do ...
