Shear Stability of Polymer Containing Fluids Tester ASTM D6278

Shear Stability of Polymer Containing Fluids Tester 

(Diesel Fuel Injector Nozzles)  ASTM D6278       

Model：JF0103

Instrument Introduction

The instrument is a new high-tech product developed with German technology. It is suitable for the shear stability determination of polymer oil. The main engine consists of a Bosch double-piston jet pump and an atomization chamber with a nozzle and a nozzle bracket. It contains polymer At a certain shear rate, the oil passes through the diesel nozzle of the diesel nozzle shear stability tester to promote the depolymerization of the polymer molecules with poor shear stability, which reduces the kinematic viscosity of the sample and is used to report the initial sample. The percent drop in kinematic viscosity at 100°C was used to measure the shear stability of polymer-containing oils.
