Process for producing polyurethane moldings |
摘要 |
Cellular or compact polyurethane moldings are produced by conveying at least one isocyanate component and at least one polyol component by a metering machine in dispensing manner into a mixing chamber via component lines to form a polyurethane reaction mixture. Subsequently, the polyurethane reaction mixture is discharged from the mixing chamber into a mold. The pressures of the components are registered by means of pressure transducers in the component lines and are transmitted to a monitoring device. The temporal profiles of the pressures are compared with reference pressure values stored in the monitoring device. A malfunction is signalled in the event of deviation of at least one of the measured pressure profiles from the reference pressure profile beyond a predetermined tolerance threshold.
