A perolita randalita tem \u00e1gua oclu\u00edda em combina\u00e7\u00e3o, o que lhe confere a propriedade excepcional de se expandir quando sujeita a temperaturas elevadas.<\/p>\n
A perlite expandida, ap\u00f3s delicados processos de esmagamento e classifica\u00e7\u00e3o, \u00e9 transformada num auxiliar de filtragem cujas part\u00edculas encravadas podem formar um bolo incompress\u00edvel, com 80-90 % de espa\u00e7os ocos, atrav\u00e9s dos quais os l\u00edquidos a filtrar passar\u00e3o, retendo os elementos s\u00f3lidos em suspens\u00e3o, mesmo os de tamanho microsc\u00f3pico.<\/p>\n
O randalite \u00e9 utilizado para a filtragem de l\u00edquidos farmac\u00eauticos ou alimentares, tais como vinho, glucose, a\u00e7\u00facar, cerveja, mostos, licores, \u00e1gua, \u00f3leos e produtos farmac\u00eauticos em geral.<\/p>\n
O randalite \u00e9 uma perlite especialmente adequada para fazer um pr\u00e9-tratamento consistente e f\u00e1cil de gerir em filtros de v\u00e1cuo. Devido \u00e0 sua baixa granulometria, permite a obten\u00e7\u00e3o de l\u00edquidos com boa limpeza.<\/p>\n","protected":false},"excerpt":{"rendered":"
