The installed viscometer that is responsible for maintaining the proportion of solvent in the mixture has an automatic washing system designed for catalytic glue control equipment that performs solvent rinsing routines that prevent the deposition of catalyzed adhesive during use. It is the same solvent used for washing that was later used to add it to the mixture that is being prepared as it is consumed.
In the viscometer the tail, driven by the pump, circulates through the measurement unit where, as a function of the time of fall of a metallic body between two inductive detectors, the viscosity is calculated. The software decides if dilution is necessary using the solvent in the tank. The rinse cycles are carried out at the time of dilution, once the unit of measure is full of solvent after dilution, a valve is opened that returns the solvent to the tank by recirculating until the software estimates that the unit has been cleaned correctly. . After cleaning, normal work continues and the solvent accumulated in the unit begins to dilute the glue. From time to time the system flushes the unit of measure if it was not necessary to dilute the glue in that time.
