Abstract

"PROCESSO APERFEIçOADO DE HIDROFOBIZAçãO DE VERMICULITA EXPANDIDA E APLICAçãO". Descreve-se um processo aperfeiçoado para produzir vermiculita expandida hidrofobizada, utilizando-se de reagentes orgânicos derivados de silício, tais como, etilsilicato, organohalogeniossilanos, siloxanos e silicones, que ao entrarem em contato com a vermiculita expandida, após a sua expansão, a uma temperatura inferior a 800<198>C, a transforma em material hidrofóbico, ou seja, hidrorepelente. O reagente orgânico reage firmemente com a superfície da vermiculita expandida, tornando-a apta a adsorver com mais eficácia, líquidos orgânicos, tais como óleos e petróleo e seus derivados, de águas industriais ou quaisquer tipo de águas contaminadas com estes líquidos assim como, óleos derramados em solos impermeáveis. O produto originado poderá ser usado também na forma de almofadas e cordões para limpeza de caixas de gorduras."IMPROVED PROCESS OF EXPANDED VERMICULITE HYDROPHBIZATION AND APPLICATION". An improved process for producing hydrophobized expanded vermiculite is described using organic silicon-derived reagents such as ethylsilicate, organohalogenosilanes, siloxanes and silicones which upon contact with expanded vermiculite upon expansion to a temperature below 800 ° C turns it into hydrophobic, i.e., water repellent material. The organic reagent reacts firmly to the surface of the expanded vermiculite, making it able to more effectively adsorb organic liquids such as oils and petroleum and their derivatives from industrial waters or any type of water contaminated with these liquids as well as oils. poured into impervious soils. The originated product may also be used in the form of pads and cords for cleaning fat boxes.
