Abstract
"MéTODO E APARELHO PARA PRODUçãO DE UMA ESTRUTURA ESPUMOSA INORGâNICA PARA UTILIZAçãO COMO PAINEL ACúSTICO DURáVEL". Um processo e aparelho para criar um painel poroso acusticamente absorvente compreendem as etapas de distribuir cimento e fibras com um misturador a seco para criar uma mistura seca e misturar de forma aquosa água, agente tensoativo e ar com um misturador aquoso para criar uma espuma. O processo e aparelho proporcionam a combinação e mistura da espuma e mistura seca em um misturador de combinação para formar um material aglutinante espumado compreendendo em uma base a úmido aproximadamente 53% até aproximadamente 68% em peso de cimento, aproximadamente 17% até aproximadamente 48% em peso de água, aproximadamente 0,05% até aproximadamente 5% em peso de fibras, e aproximadamente 0,01% até aproximadamente 10% em peso de agente tensoativo. O material aglutinante espumado é então seco ou curado em uma câmara de secagem. O material aglutinante espumado seco pode então ser texturizado com um rolete de estampagem. O material aglutinante proporciona bom desempenho acústico com durabilidade, e resistência à umidade, otimizadas."METHOD AND APPARATUS FOR PRODUCING AN INORGANIC FOAM STRUCTURE FOR USE AS A DURABLE ACOUSTIC PANEL". A process and apparatus for creating an acoustically absorbent porous panel comprises the steps of dispensing cement and fibers with a dry mixer to create a dry mixture and aqueous mixing of water, surfactant and air with an aqueous mixer to create a foam. The process and apparatus provides the combination and mixing of the foam and the dry mixture in a combination mixer to form a foamed binder material comprising on a wet basis approximately 53% to approximately 68% by weight of cement, approximately 17% to approximately 48%. by weight of water, about 0.05% to about 5% by weight of fibers, and about 0.01% to about 10% by weight of surfactant. The foamed binder material is then dried or cured in a drying chamber. The dried foamed binder material can then be textured with a stamping roller. The binder material provides good acoustic performance with optimized durability and moisture resistance.
