HP-TD500 cardboard type quite degree measuring instrument (also known as cardboard stiffness tester, stiffness of the paper instrument, stiffness instrument) is an international standard of general Taber, Taber) type stiffness tester, the main technical parameters of the instrument conforms to the relevant provisions of national and international standards. Stiffness is a measure of the anti bending strength index of paper and paperboard, Taber type stiffness tester is instrument for determining the indicators and Taber stiffness belongs to static bending strength indicators.
Product features:
1, Taber stiffness tester is according to the torque on the shaft center of the static balance principle of the design. By measuring the force or torque needed to be clamped at one end to a given point of view, the stiffness of the sample is obtained. The bending force of the sample is the same as that of the.
2, Taber stiffness tester is based on two-point loading method and moment balance principle of the design of a special test device. The instrument is composed of a transmission part, a measuring part and a supporting and mounting base part.
3, the transmission part of the motor through the intermediate drive chain to the angle, the angle of rotation to drive the paper frame work.
4, the measurement of the strength of the plate, the angle plate, diamond shaped body, paper clips, paper and other pieces of paper. Motor driven disc rotation, wheel angle on the paper pushing frame and rotate together, push the paper rack pushing paper round stick and sample contact specimen bending over. Sample holder to the paper clamp jaw, and a paper clamping device is arranged on the diamond of the swing body, in specimen rigidity under the action of specimen under force and diamond pendulum body subjected to moment action, the hem in the moment is pushed to rotate, when the pendulum body and angle relative to the disk rotation reached 15 DEG (or 7.5 degrees) stop. At the same time, the system reaches the moment balance. The zero line of the angle plate will indicate the torque value of the tested sample, which is expressed by M and mN.
