In the quality control of paper and sheet composite materials, interlayer bonding strength is a key indicator. As a professional testing equipment, the paper interlayer bonding strength tester provides technical support for multiple fields with accurate detection capabilities. Its application, accuracy guarantee, and calibration specifications have clear standards.

1Widely applicable fields

The application of this device covers multiple industries related to paper and composite materials：

1、Paper industry:Monitor the production quality of raw paper and finished paper, optimize pulp making, forming and other processes, avoid problems such as delamination of packaging cardboard, powdering and fuzzing of cultural paper, and ensure that products comply with GB/T 26203Waiting for standards.

2、Packaging materials industry:Detecting corrugated cardboard and paper -Verify the anti vibration and compression capabilities of materials such as film composite packaging to prevent packaging failure due to insufficient interlayer bonding.

3、Printing and paper processing industry:Checking the interlayer strength of paper before printing to avoid Pulling hair ", testing the structural stability of composite materials after deep processing to ensure the durability of finished products such as picture books and gift boxes.

4、In the field of specialty paper and functional materials:Control the internal bonding stability of special papers such as filter paper and battery separator paper to ensure filtration accuracy and battery safety.

IIMulti dimensional accuracy guarantee

The device ensures detection accuracy through its structure, data collection, sampling control, and calibration mechanism

1、Core structural design:The internal combination measuring instrument adopts a two-stage gravity overlapping structure to counteract external interference and ensure stable release of impact energy; fixed 90° standard impact angle to avoid errors caused by angle fluctuations.

2、High resolution data acquisition:equip 5000 Pulse high-precision encoder with data acquisition resolution capability of up to0.001lbf/in²， Accurately capturing changes in force values; Component range control indication error,A档（0~500J/M²）±1J/M²，B档（500~1000J/M²）±2J/M²。

3、Standardized sampling control:Specialized sampler cutting 25.4mm140mmSample, parallelism of two long sides ≤0.015mmStandard sampling table automatic cutting25.4mm25.4mmSample, synchronously pressurized and pressure adjustable to ensure uniform sample size and consistent pre-treatment conditions.

4、Real time calibration assistance:Comes with calibration tools to support real-time on-site calibration and regular verification of equipment accuracy; Clearly require double-sided tape to have a greater adhesion to stainless steel than 486N/mTo avoid auxiliary materials affecting the test results.

Scientific calibration cycle

The calibration cycle should be determined comprehensively based on the usage of the equipment

1、Basic cycle:When in regular use and stable environment, it is recommended to 12 Calibrate once a month to maintain data accuracy.

2、Shorten cycle scenario:High frequency use (daily detection exceeding 50 Group), harsh environment (large temperature and humidity fluctuations, high vibration and dust), key testing areas (military paper products, medical packaging), it is recommended to3-6Monthly calibration; Equipment collision, repair, or data fluctuation exceeding tolerance require immediate calibration.

3、Calibration basis:strictly adhere to GB/T 26203TheASTM T569 pm-00Standard and manufacturer's calibration manual, using standard instruments to ensure compliance and traceability.
