Abstract
"PROCESSO E APARELHAGEM PARA PREPARAR POLìMEROS, UTILIZANDO UM DISPOSITIVO ULTRA-SÈNICO DE CORRENTE LATERAL PARA MONITORAR E CONTROLAR AS PROPRIEDADES DO POLìMERO". As propriedades de um produto de material resinoso são controladas num sistema de manufatura monitorando e controlando parâmetro de processo em linha. A monitoração e controle em linha incorpora um sistema de medição no sítio que pode monitorar o produto no processo pelo uso de um dispositivo ultra-sónico de corrente lateral. O dispositivo de corrente lateral provê vantajosamente em linha medidas em tempo real das propriedades acústicas do produto (por exemplo, velocidade, atenuação) sob condições que são independentes de condições de corrente de processo. O dispositivo de corrente lateral controla a temperatura, pressão, e taxa de fluxo embora do lado de dentro o dispositivo de corrente lateral e a velocidade e A atenuação são medidas sob estas condições de temperatura, pressão e taxa de fluxo predeterminadas. As propriedades acústicas (por exemplo, velocidade, atenuação) do produto, são usadas para predizer as propriedades do produto, e provê o sistema de controle de processo com análise das propriedades acústicas usando relações derivadas entre as propriedades físicas do produto e as propriedades acústicas. As diferenças entre as propriedades de produto preditas e desejadas são usadas para controlar parâmetros de processo. O processo pode ser usado numa variedade de plantas de processos químicos.
