Abstract

"NúCLEO DE GESSO PARA MOLDE DE PNEUMáTICO". A criação de um núcleo de gesso para fundir um anel de molde de banda de rodagem de pneumático a partir de uma mistura de gesso, e água despejada dentro de um molde de núcleo onde a quantidade de água necessária para o processo é limitada pelo dispositivo adequado tal como um super emoliente somado à mistura e um inserto pré seco somado ao núcleo."PLASTER CORE FOR PNEUMATIC MOLD". The creation of a plaster core to fuse a tire tread mold ring from a plaster mixture, and water poured into a core mold where the amount of water required for the process is limited by the appropriate device such as a super emollient added to the mixture and a pre-dried insert added to the core.
