Compressive Strength Tester By Cross-Direction Compression For Pakaging Paperboard Short displacement Compression Tester

Compressive Strength Tester By Cross-Direction Compression For Pakaging Paperboard Short displacement Compression Tester 0

The Compressive Strength Tester, specifically the SCT-01 Short Span Compression Tester, is an essential tool for evaluating the compressive strength of paper and board materials. This advanced testing equipment is designed for industries involved in packaging, food, medicine, and education, providing accurate and reliable measurements crucial for product quality and compliance. The SCT-01 is adept at determining compressive strength in both machine and cross directions, ensuring comprehensive assessment for various applications.

Application of SCT-01 Short Span Compression Tester

The SCT-01 Short Span Compression Tester is specifically engineered for testing the compressive strength of paper and board materials used in manufacturing containers and boxes. It is particularly suitable for materials with a grammage range of 100 g/m² to 400 g/m². This Compressive Strength Tester is invaluable in ensuring that packaging materials meet industry standards and customer expectations. The testing process does not assess strain at break but focuses solely on the material's compressive capabilities.

System Description of SCT-01 Short Span Compression Tester

The SCT-01 features a robust design with two clamps that hold a test piece measuring 15 mm in width. Each clamp consists of a stationary jaw and a movable jaw, both equipped with high-friction surfaces to ensure a secure grip on the test specimen. The clamps maintain a constant clamping force of 2300 ± 500 N, facilitating reliable and consistent results across multiple tests.

At the start of each test, the free span between the clamps is set to 0.70 mm ± 0.05 mm. Once initiated, the clamps move toward each other at a speed of 3 mm/min ± 1 mm/min, applying pressure until compressive failure occurs. The Compressive Strength Tester is equipped with a force measuring unit, PLC control, and an HMI touch screen display, enabling precise determination of the maximum compressive force.

Furthermore, the device includes a calibration feature using standard weights, ensuring that the load cell is accurate. The clamping force exerted by the jaws is displayed in newtons, providing additional clarity during testing.

Technical Features

  • PLC Controlled and HMI Operation: The intuitive interface ensures ease of use and precise control over testing parameters.
  • Pneumatic Sample Clamping: This feature allows for adjustable clamping force, accommodating various test piece dimensions.
  • Adjustable Test Speed: Tailor the speed of testing to meet specific requirements.
  • Safety Features: Equipped with an emergency stop button and over-range protection to enhance user safety.
  • Multi-Unit Display: The tester displays measurements in N (Newtons), kgf (Kilogram-force), and lbf (Pound-force).
  • Data Output: An embedded dot matrix micro printer allows for easy documentation of test results. Additionally, an RS 232 COM port and optional computer software facilitate data management and analysis.

Test Principle

To conduct a test with the Compressive Strength Tester, a sample measuring 15 mm wide is placed between the clamps. The clamps are positioned 0.70 mm apart and forced together until failure occurs. The maximum force recorded during this process is used to calculate the compressive strength of the material.

Test Procedures

  1. Securely clamp the test piece in the jaws of the tester.
  2. Initiate the movement of the jaws and record the maximum compressive force indicated on the display.
  3. Perform tests on a minimum of 20 test pieces in both the machine direction and cross-direction.
  4. If additional tests are required on a single specimen, ensure that the test area has not previously been subjected to clamping during earlier tests.

FAQs

What is the compressive strength in the SCT test?
The compressive strength refers to the maximum compressive force per unit width that a test piece of paper or board can withstand before failure, expressed in kilonewtons per meter.

What is the compressive index in the SCT test?
The compressive index is a measure of the compressive strength of the material relative to its density.

How often should the Compressive Strength Tester be calibrated?
Regular calibration is recommended to maintain accuracy, typically before major testing sessions or as per the manufacturer’s guidelines.

Can the SCT-01 be used for materials outside the specified grammage range?
While the SCT-01 is optimized for materials between 100 g/m² and 400 g/m², testing outside this range may yield less reliable results.

Is training available for new users of the Compressive Strength Tester?
Yes, training sessions can be arranged to ensure that users are fully familiar with the operation and maintenance of the tester.
