Urea-formaldehyde glue viscoMeter

The urea-formaldehyde glue viscometer measures the internal resistance of a fluid by generating torque through the rotation of a rotor in the glue solution. It is used to monitor the degree of polycondensation during the synthesis of urea-formaldehyde resin, ensuring the stability of the adhesive's coating and penetration properties. In the wood processing industry, it is employed to control the pressing process conditions for plywood.
Selection
When selecting, consider matching the viscosity range of the urea-formaldehyde adhesive being tested with the instrument's measurement range. The rotor specifications should be suitable for the sample container size. The temperature control system should meet the requirements of the actual testing environment. Pay attention to the correspondence between the instrument's measurement accuracy and the precision of the production process control, and ensure that the operation interface aligns with the usage habits of the personnel.
