Utilização do Lodo de Estação de Tratamento de Efluentes da Indústria de Injeção Plástica como Matéria-Prima para Indústria Cerâmica

Abstract

The plastic injection industry has a fundamental importance to the national economy because it is responsible for the production of primary inputs for many industries from electronics. These companies produce effluents coming from units of paint by blasting and spraying. This waste requires special treatment for their separation, storage and disposal. This paper studies an alternative way to use this waste in the red ceramic industry, evaluating parameters that influence important properties of artifacts made of red clay as density, porosity and bending strength, measured for mixtures of 2%, 5% and 10% by weight of waste, for the clay used, the results show that there is influence of this material in solid state reactions and can improve the properties cited.
