Overview
WDK-01 intelligent paper tensile tester is a professional testing instrument under the CHENCHI brand, specially designed for tensile strength testing of paper and Cardboard. The instrument provides a variety of range options such as 30N, 300N, 500N, etc. It is suitable for a wide range of testing requirements from napkins, toilet paper to cultural paper, Encasement paper and even ultra-high strength paper. It can accurately detect tension, tensile strength, elongation, elongation, break length, tensile energy absorption, tensile index, tensile energy absorption index, fracture time and other parameters. High Accuracy and good repeatability, it is an ideal equipment for R & D institutions, paper mills, Encasement industry and Quality control departments.

2. Long life: using precision ball screw transmission and high-quality machining technology, it is durable and can provide professional software upgrade services.
3. Wide range of adaptability, complete functions: a variety of ranges are available, suitable for all paper and Cardboard, can detect tension, tensile strength, elongation, elongation, fracture length, tensile energy absorption, tensile index, tensile energy absorption index, fracture time and other parameters.
4. Easy to use, easy to operate: High-speed ARM processor, High Degree of automation, Fast data collection; Equipped with 7-inch touch LCD screen, Chinese display, friendly man-machine interface. Fully automatic test, with data statistical processing function, standard micro-printer, can also be connected to computer operation, display and save Linear dispersion.
5. The test is fast and effective: the test speed, sample width, sample gram weight and other parameters can be preset, and the built-in force value multi-unit conversion function can be used to convert the result units, improving the test efficiency.
6. Easy Measurement and calibrating: The Force Sensor is located above and connected to the upper chuck. Users or third-party calibrating departments can easily perform Indication Error calibrating by hanging the standard weight on the upper chuck.
Principle
The instrument uses the constant-speed stretching method (or constant-speed loading method) for testing. During the test, the sample is fixed between the upper and lower chucks, and the synchronous belt drive is driven by a stepper motor. The precision ball screw and linear bearing system are driven to apply a tensile force to the sample at a preset constant speed until the sample breaks. The High Accuracy Force Sensor monitors and records the change of the force value during the stretching process in real time, while the system records the elongation displacement of the sample. The built-in high-speed ARM processor quickly collects and processes these data, and finally calculates a series of mechanical properties such as tension resistance, tensile strength, elongation, and fracture length.
Applications
R & D institutions, paper mills, Encasement industries, Quality control departments
Standards
ISO1924/2 "Paper and Cardboard - Determination of tensile strength (constant speed tensile method) ", GB/T1 2914-91 "Paper and Cardboard - Determination of tensile strength", GB/T 453-2002 "Paper and Cardboard - Determination of tensile strength (constant speed loading method) ", QB/T1670-92 "Electronic tensile strength tester"
Steps
1. Turn on the power supply (AC220V 50HZ) and turn on the instrument.
2. Choose the appropriate test range on the instrument according to the type of sample to be tested (e.g. paper, Cardboard) and the expected strength.
3. Set test parameters through a 7-inch touchscreen, including test speed, sample width, sample weight, etc.
4. Cut the sample to the specified size and install it evenly between the upper and lower collets to ensure clamping.
5. Start the test on the touchscreen, and the instrument will automatically stretch the sample at a constant speed until it breaks.
6. After the test is completed, the instrument automatically calculates and displays the results (such as tension resistance, elongation, etc.).
7. You can directly print the test statistical report through the standard micro printer, or choose to connect to the computer to save detailed data and tensile Linear dispersion.
Notice
The instrument should be placed on a stable workbench to avoid vibration.
* Power supply voltage is AC220V 50HZ before use.
* Select the appropriate range according to the sample characteristics to avoid damage to the Sensor due to excessive range use.
When installing the sample, ensure that the sample is flat, vertical, and evenly clamped by the chuck to avoid test errors.
Regularly clean and maintain the instrument to maintain the cleanliness and lubrication of moving parts such as guide rails and screws.
The instrument has functions such as force overload protection, stroke upper and lower limit protection, etc. Non-professionals should not adjust or disassemble the safety protection device at will.
* Measurement calibrate using certified standard weights in strict accordance with operating procedures.
When connecting your computer, ensure software compatibility and follow the instructions to install the driver correctly.
