KJ-6031N Computerized Loop Tack Tester

Core Product Features

Precision and Efficiency, Authoritative and Compliance-Compliant

● The equipment, featuring advanced mechatronic design, demonstrates multiple advantages in detection accuracy, operational user experience, and standard compatibility, ensuring comprehensive precision and efficiency in testing processes. This enables enterprises to achieve refined quality control.

● Precision breakthrough addresses industry pain points: It completely resolves the issues of inaccurate and inconsistent initial adhesion test data. Compared to the traditional rolling method, the ring testing method yields more consistent results, effectively minimizing the impact of factors such as temperature and human intervention on test outcomes, thereby significantly enhancing the reliability and reference value of the test data.

● Digital presentation delivers intuitive and reliable results: The entire testing process is fully automated, with test results displayed simultaneously in both precise data and dynamic graphics, clearly illustrating the entire force variation trajectory. This ensures complete authenticity and accuracy of the tests, eliminating the need for manual calculations, and enabling direct application for data archiving and process optimization.

● Multi-standard compatibility ensures authoritative and reliable data: Fully compliant with numerous international and domestic authoritative standards, it ranks among global standard testing frameworks, guaranteeing that testing procedures and data accuracy meet industry specifications. This results in widely recognized test outcomes, meeting diverse enterprise needs including exports, compliance quality inspections, and R&D comparisons.

Testing Principle

Scientifically rigorous and operationally standardized (with added test flowchart)

The device operates based on the core logic of cyclic initial adhesion testing, featuring a scientifically rigorous and highly automated process that effectively minimizes human operational errors, ensuring stable and reliable test results. The specific testing principle is as follows:

The sample is formed into a ring shape (with the adhesive side facing outward). After complete contact with the standard float glass testing plate at a constant speed of 300 mm/min, the instrument automatically reverses the movement of the ring-shaped sample relative to the test plate, achieving complete separation at the same constant speed. The maximum force generated during this process represents the initial adhesive force of the sample. This testing method accurately replicates the actual initial adhesion conditions encountered during product use.
