ZD Tensile Tester

Test legend

Used to test the tensile strength of paper and paperboard Z, i. e. the internal bond strength of paper and paperboard. Mainly used in sand paper, paperboard, cardboard, gray board paper, kraft paper, white cardboard, parchment paper, copperplate paper board, the interlayer bonding strength was low or uneven distribution, may lead to problems in tile paper and cardboard printing machine using viscous ink when if the interlayer bonding the strength value is too high, will hinder the processing incision of cardboard, high bonding strength between layers also means the waste of raw materials and energy, our purpose is according to the specific requirements of customers, the paper web width consistent strength in the production process.

The use of LB-T541 interlayer bonding strength tester, can according to the specific requirements of customers, quickly obtain reliable bonding strength between layers, the strength of the whole paper net width adjustment consistent within the instrument testing process is fully automatic, easy operation.

Product features

Using high precision force sensor, the U.S. computer chip high speed sampling control, stepper motor, precision ball screw drive, in addition the reasonable design, precision machining, ensure the instrument with high accuracy and repeatability.

The utility model can be automatically completed by pressing and pasting the adhesive tape, the pressing time and the separating sample. The utility model has the advantages of convenience and less artificial error, and greatly improves the testing accuracy.

LCD Chinese display, friendly man-machine interface operation, with test data processing function, printer printing, you can connect to the PC through software.

The test speed, bonding pressure and pressurization time can be preset to facilitate the scientific experiment and analysis of schools, scientific research units and other departments.

The upper and lower pressing heads are easy to take down, which is convenient for cleaning, leaving the residue in the adhesive tape when the experiment is made, and the utility model is convenient for the connection of the standard sensors to carry out the force value calibration.

Test description

By sampling from the sample cutting equipment uniform (50 * 50) square sample mm, sample in the positive and negative sides were stuck with double-sided adhesive, and then tear the two sides glue the specimen is placed in the head start center, instruments, pressure head began to rise, and head to the sample after applying contact pressure, pressure to stop until the bonding pressure set value, and keep the pressure to the pressure after the set time, under the pressure head began to move down the test, until the sample separation test is completed under the pressure head will automatically return to the starting position, read the value of the determination results.

Note: double adhesive with strong adhesive strength should be chosen, such as upper and lower pressure head during test and sample degumming, then the result should be discarded.
