Computerized tensile tester for peel tensile test

1. Introduction of adhesive

Adhesive is a substance with very good adhesive properties. It acts to connect objects by surface bonding by adhesion and cohesion. Adhesives can join homogeneous or heterogeneous surfaces together with continuous stress distribution and low weight. Adhesive bonding is especially suitable for continuous thermoplastics of different materials, different thicknesses, ultra-thin specifications and complex components, and is widely used in various industries. Adhesives can be divided into thermosetting type, hot melt type, room temperature curing type, pressure-sensitive type, etc. according to the method; according to the application object, it can be divided into structural type, non-structural type or special adhesive; according to the form, it can be divided into water-soluble type and water-emulsion type. , solvent-based and various solid-state.

2. Test methods related to adhesive product testing

The test types of adhesive products mainly include 90 degree peeling, 180 degree peeling, T peeling, etc. The relevant test methods are as follows:

GB/T 2790 adhesive 180 degree peel strength test method for a flexible-to-rigid test specimen assembly

ISO 8510-2 adhesive – peel test for a flexible-bonded-to-rigid test assembly – part 2: 180 degree peel

ISO 8510-1 adhesives – peel test for a flexible-bonded-to-rigid test specimen assembly – part 1: 90 degree peel

ISO 527-1 plastics – determination of tensile properties – part 1: general principles

GB/T 2791 adhesive – T peel strength test for a flexible-to-flexible test specimen assembly

GB/T 2792 measurement of peel adhesion properties for adhesive tapes

ISO 29862 self-adhesive tapes – determination of peel adhesion properties

GB/T 4851 test method for holding power of pressure sensitive adhesive tapes

3. features of film and tape 90 degree and 180 degree peel strength tester

3.1. Using AC servo motor and AC servo speed control system to control the test process, the control accuracy and quality are greatly improved, stable, efficient, low noise (basically no noise at low speed) and the control speed range is greatly widened (0.05-500mm/min) ), which is not only conducive to low-speed testing of conventional materials (metal, cement, concrete, etc.), but also conducive to high-speed testing of non-metallic materials (rubber, etc.), and can also be used to quickly adjust the test space at no-load, saving auxiliary test time. This test speed meets the requirements for most metal and non-metallic materials.

3.2. The deceleration mechanism composed of synchronous toothed belt and precision ball screw pair makes the structure more concise and bright, and the transmission efficiency is greatly improved, more coordinated.

3.3. The double-space structure with independent tension and compression is adopted, which is convenient to operate and avoids the troublesomeness of changing different test accessories when tension and compression are in the same space.

3.4. Sensors of different specifications can be configured according to requirements, which greatly widens the test range and meets the measurement requirements of different test loads.

3.5. The main engine adopts a full-spray plastic shell, which is elegant and beautiful in shape.

3.6. Using advanced control technology, it has three closed-loop control modes of stress, strain and displacement. Each control loop can be automatically switched, and can achieve a smooth transition without impact when switching between modes, and can display the test force, peak value and displacement, speed, test status, test curve, etc.

3.7. It can control and maintain the rate of test force, deformation and displacement.

3.8. It can realize the fast/slow lifting and lowering adjustment of the beam when the sample is clamped, and the operation is flexible and can be switched at will.

3.9. It has the function of returning to the initial position after the test, which is efficient and fast.

3.10. It has perfect limit protection function, overload, overcurrent protection, automatic shutdown of test break and other functions, which is reliable and safe.

3.11. Self-built powerful test database, test data can be saved, queried and called at any time.

3.12. Provide a variety of report printing interfaces, users can edit reports in any format according to their needs, and print them out;

3.13. The whole control system has high cost performance and high reliability.

3.14. Carry out tensile tests on materials according to national standards or standards provided by users, count and process test data, and then output and print various required test curves and test reports. Load-time, load-displacement, and displacement - Time, deformation-time and other test curves are displayed during test. Test curves can be enlarged, compared, and traversed, and the test process is monitored, very smart and convenient.

3.15. Provide professional users with "Standard Addition Program Editor" software, users can flexibly add required standards according to actual needs;

3.16. The test software under the Windows platform has strong data and graphics processing functions, can print out complete test reports and test curves in real time, and can reserve data interfaces to directly connect to the comprehensive information management network of the enterprise (laboratory). It can also be customized according to the specific situation of the user's local area network.
