Abstract

preparação de fluxo com viscosidade dinâmica aumentada contendo k2alf5 desidratado, método para a produção do mesmo e método para o uso do mesmo. a invenção apresenta preparações aquosas de fluxo com viscosidade dinâmica aumentada. nas preparações de fluxo, o k2alf5 irreversivelmente desidratado (também denominados de k2alf5 ortorômbico ou sal de fase ii) provoca o aumento da viscosidade dinâmica se as preparações aquosas de fluxo são envelhecidas, i.e., é mantido o contato entre a água contida na preparação e o k2alf5 irreversivelmente desidratado durante um certo intervalo de tempo, de preferência, durante pelo menos doze minutos. a viscosidade maior melhora o processo de soldagem, por exemplo, porque é perdida menos preparação de fluxo que cai das partes a serem soldadas.
