Product Introduction 
The internal bond strength Tester uses the Scott type impact principle. A paperboard specimen is subjected to impact at a specified angle and weight, and the energy absorbed during interlaminar peeling is measured to characterize the internal bond strength of paper and paperboard. The instrument features an integrated sample preparation and testing design for convenient preparation and simple operation. Mechanical pressing ensures consistent sample preparation pressure, while a high-precision angle sensor ensures accurate results. It can test five specimens simultaneously, with a 7-inch touchscreen for data display, multiple unit switching, and result printing. The weighted body ensures stable impact and good repeatability, making it suitable for evaluating the interlaminar bonding performance of paperboard, coated paper, and white card.

Main Technical Specifications 

FAQ 
1. What materials is the internal bond strength tester suitable for?
It is suitable for interlaminar peel strength testing of various papers and paperboards, including paperboard, coated paper, white card, and composite board, for evaluating interlaminar bonding performance.
2. What is the testing principle?
A paperboard specimen is subjected to impact at a specified angle and weight. The energy absorbed is measured to indicate the interlaminar peel strength. The impact angle is 90° with 0.01° accuracy.

3. What standards does the equipment comply with?
It is designed according to TAPPI-UM403, TAPPI T569, and GB/T 26203-2023 for internal bond strength (Scott type) determination of paper and paperboard.
4. Can result units be switched?
Yes. Result units can be freely switched among ft.lb/1000.in², Kg.cm, and J/m² to meet different standards and user preferences.
5. How many specimens can be tested at once?
The standard configuration tests 5 specimens at once, with specimen size 25.4×25.4mm, improving detection efficiency.
6. How is repeatability ensured?
The weighted body ensures stable impact, mechanical pressing ensures consistent sample preparation pressure, and the high-precision angle sensor ensures angle accuracy, resulting in good repeatability.
