Initial Adhesion Tester

The initial - tack tester, also known as the initial - tack property tester or adhesive tape tackiness tester, is an instrument specifically used to measure the initial tackiness of materials. The following is a detailed description of its main uses, compliance standards, and technical parameters:

I. Main Uses

The initial - tack tester is mainly used to test the initial tackiness of products such as adhesive tapes, medical patches, self - adhesive labels, and protective films. By simulating the actual use environment of adhesion, it tests the adhesive performance of these products when they are in brief contact with the adhesive surface under slight pressure. This device is widely used in multiple industries, including packaging, adhesives, printing, and pharmaceuticals, providing important data for product performance evaluation, quality control, and research and development. Specifically: - **Packaging Industry**: It is used to test the adhesive performance of adhesive tapes, carton - sealing adhesives, etc., ensuring the integrity of packaging during transportation. - **Adhesive Industry**: It is used for research and development and quality control. By testing the initial tackiness of different adhesives under various conditions, it provides data support for the development of new adhesives. - **Printing Industry**: It tests the tackiness of printing labels, such as trademarks and colored labels on self - adhesive labels, ensuring the reliability and durability of label products. - **Pharmaceutical Industry**: It tests the initial tackiness of adhesive materials in pharmaceutical packaging and medical plasters, ensuring the effectiveness of products and the medication experience of patients. In addition, the initial - tack tester can also be used to test the initial tackiness of office supplies such as sticky notes, and to evaluate the force required for the label to separate from the test substrate.

II. Compliance Standards

- GB 4852 *Test Method for Initial Tackiness of Pressure - Sensitive Adhesive Tapes (Rolling Ball Method)* - JIS Z0237 (Japanese Industrial Standard) and other related standards

III. Technical Parameters

- **Testing Principle**: Adopting the inclined - plane rolling - ball method. When a slight pressure causes a brief contact between the steel ball and the adhesive surface of the test specimen, the adhesion of products like adhesive tapes or labels to the steel ball is used to test the initial tackiness of the specimen. - **Adjustable Inclination Angle**: The testing inclination angle can be freely adjusted within the range of 0 - 60° according to users' needs to adapt to the testing requirements of different products. - **Tabletop Width**: Usually about 120mm to ensure there is enough space to place the test specimen. - **Test Area Width**: Generally about 80mm, providing a sufficient operational area for the test. - **Standard Steel Balls**: The size range is usually from 1/32 inch to 1 inch. Steel balls of different sizes are used to test products with different adhesive forces. - **External Dimensions**: Vary depending on the equipment and model. Generally, the length is between 300 - 450mm, the width is between 120 - 160mm, and the height is between 150 - 200mm. - **Weight**: Also varies depending on the model and brand. Generally, it does not exceed 10kg, making it easy to move and place.
