Thermal and Mechanical Reinforcement Particle Expanded Perlite Granules, with defined specific thermophysical and chemical properties of thermal conductivity, SinteringMelting Point and acidity (pH).
The present Invention concerns a strengthening Mechanical and Thermal particles of expanded Perlite Granules size Distribution and Particle Shape defined,The Product obtained has an apparent density of the Order of 0.1 g / cm3 to 0.4 g / cm3.The obtained granular Expanded Perlite Product allows its use in refractory Insulating reinforced monolithic formulated with aluminous Cement.The use of Perlite incorporates Aerated Porosity, creating a product with good Properties of Thermal insulation and temperature Resistance.The Product can be used as load of low specific weight in formulations of cylinders and / or Preformed exothermic Insulating sleeves, also known as,Which are used as feeders of Liquid Metal in the manufacture of castings, replacing the use of cenoesferas in these formulations.
