Adhesion Tester

The tack - holding tester, also known as the tack - holding property tester, tack - holding force tester, or holding - power tester, is a device specifically used to test the holding power of adhesive products. The following is a detailed description of the main uses, compliance standards, and technical parameters of the tack - holding tester:

I. Main Uses

The tack - holding tester is mainly used to test the tack - holding properties of adhesive products such as adhesive tapes, medical adhesives, self - adhesive labels, protective films, plasters, and rubber plasters. By simulating the adhesion and stress conditions in actual use environments, it tests the ability of adhesive products to resist displacement, that is, the ability of adhesive specimens to resist peeling. This device is widely used in the research and development, production, and quality control of adhesive products, providing important data for product performance evaluation and improvement.

II. Compliance Standards

The design and manufacture of the tack - holding tester comply with a series of national and international standards to ensure the accuracy and reliability of test results. Among the more common standards are: - GB 4851 *Test Method for Tack - holding Property of Pressure - Sensitive Adhesive Tapes* - ASTM D3654 *Standard Test Method for Shear Adhesion of Pressure - Sensitive Tape* - JIS Z0237 *Test Methods for Pressure - Sensitive Adhesive Tapes and Pressure - Sensitive Adhesive Sheets* These standards specify in detail the test methods for the tack - holding tester, specimen preparation, test conditions, etc., providing a unified standard for the use of the tester.

III. Technical Parameters

- **Standard Pressing Roller**: Usually 2000g±50g, used to apply a certain pressure to the specimen to ensure a tight adhesion between the specimen and the test plate. - **Weight**: Generally 1000g±10g (including the weight of the loading plate), used to apply a certain gravitational force to the specimen during the test to simulate the stress conditions in actual use. - **Test Plate**: The dimensions are usually 60mm (length) × 40mm (width) × 1.5mm (thickness), used to fix the specimen and conduct the test. - **Timing Range**: Generally 0 - 10000 hours or longer to meet different testing requirements. Some devices also have an ultra - long - time timing function, which can reach up to 9999 hours or more. - **Testing Stations**: Usually 6 or more, allowing multiple sets of test items to be carried out simultaneously to improve testing efficiency. - **External Dimensions**: Generally about 600mm (length) × 240mm (width) × 400mm (height), facilitating placement and movement. - **Power Supply**: Usually AC 220V 50Hz to ensure the normal operation of the tack - holding tester.
