Shear Stability Tester

Shear stability tester D6278 dd is one of the laboratory equipments that evaluates the shear strength of polymer containing liquids. The test method uses the European Diesel Injector Test Equipment to measure the adhesion percentage in liquids containing polymer assessed by a diesel injection procedure at 100 ° C. Loss of adhesion indicates damage to the polymer due to the cutting of the lid.

D7109-Evaluates the shear stability of a polymer containing fluids. The test method measures the loss of adhesion at mm2 / s and the percentage of fluids containing polymer at 100 ° C, as measured by the European diesel injection procedure using European diesel injector testers. Loss of adhesion indicates damage to the polymer due to the cutting of the lid. Loss of fatigue is assessed after 30 and 90 turns are cut.

Description Shear Stability Tester

The device consists of a liquid tank, an electric motor with a double density pump, a spray atomization chamber with a diesel injector and a liquid cooling tank with an ambient temperature of 20 to 250C.

The liquid reservoir is open from the top, calibrated to a volume of approximately 250 ml, an internal diameter of 45 mm, and volume units. Equipped with an internal liquid dispenser. Clockwise 40mm diameter receiver distribution board with defined edges. The dispenser reduces the tendency for liquid wastewater.

The temperature is measured with a thermometer suspended in the middle of the liquid reservoir. The base of the thermometer lamp should be 10-15mm from the opening of the drain hose. Other temperature indicators located in the same location can also be used. The socket is equipped with a tripod.

The three-way stopper is a tight fitting taper type that cannot be replaced with a nominal size 8mm nose. An open plastic tube is used to connect the tripod stopper to the pump inlet.
