China Bending Tester Cardboard Paper Taber Stiffness Test

Bending Tester Cardboard Paper Taber Stiffness TestCY306 cardboard stiffness tester (also known as cardboard stiffness instrument,
paper stiffness meter, stiffness meter) is the international standard generic
Tai Boer (Taber)-type stiffness tester, main technical parameters of the instrument
in line with national standards and the relevant provisions of international standards. Stiffness is a measure of bending strength of paper and cardboard targets, Tai Boer-type instrument is to measure the stiffness index of the instrument, Taberstiffness is the static bending strength indicators.
Feature
1. Taber stiffness tester is based on the static torque on the shaft center of the design principles of balance. By measuring the sample is clamped at one end was bent to the angle required for a given force or torque, to get the value of the sample stiffness. Specimen bending force is acting on a curved length of the same.
2. Taber stiffness loading instrument is based on two principles of law and the torque balance design special test equipment.Equipment from the transmission part, measure part and supporting part of a combination of installed base.
3. drive through the middle part of the drive chain from the motor to the angle plate, angle plate frame rotating drive to push the paper work.
4. measured in part by the intensity of plate, angle plate, put the diamond body, Paper Holder, aircraft and other pieces of paperto push the composition. Motor rotation angle plate, angle plate on the frame to push the paper along with rotation, pushing the paper to push the shelf paper contact with the specimen small round rod bent over the sample. Sample holder in the Paper Holder jaw, while the jam is installed in the diamond body swing, rigidity in the sample under its own power, while the diamond sample placed under the body has been the role of torque in the torque effect hem body pushed rotation,
when the pendulum relative to the body and angle plate angle to 15 ° (or 7.5 °) to stop, then the system to achieve torque balance. Angle plate zero line will indicate the kind of torque values to be tested to mN · m said.
Application
Applying in testing stiffness and resiliency of paper and cardboard (thickness ≤1mm) according international Taber method.
