Product Overview

The KR‑417 Scott‑style internal ply‑bond strength tester quantifies Z‑direction inter‑layer bonding performance for multi‑ply paper and paper‑board materials. Following classic Scott pendulum‑impact principle, the instrument delivers controlled 90‑degree pendulum impact energy to trigger internal delamination of standard specimens. It calculates absorbed impact energy to evaluate fibre‑interlayer adhesion condition, which is a critical quality indicator to predict delamination risks during printing, die‑cutting and carton‑forming processing.

Two configuration variants are available: KR‑417A push‑button version and KR‑417B touch‑screen version. This laboratory‑grade device complies with GB/T 26203‑2010, TAPPI‑T569pm‑00 and TAPPI‑T833pm‑94 specifications. It is widely adopted by paper‑mills, corrugated‑carton manufacturers, packaging‑R&D centres and accredited third‑party testing labs for incoming‑material inspection, pulp‑formula optimisation and finished‑paper quality grading.

Core Product Competitive Advantages

1. Five‑Position Multi‑Sample Test Station for High Throughput Equipped with five parallel specimen mounting positions. Operators can load up to five standard specimens in one batch, cutting repeated fixture‑setup workload and greatly improving lab QC‑sampling efficiency for high‑volume test tasks.
2. Adjustable Pneumatic Specimen‑Compression System Dual‑standard compression‑pressure presets: (690 ± 21) kPa and (1034 ± 34) kPa. Compression parameters can be further custom‑tuned according to specimen thickness. The 0‑400 N continuously‑adjustable clamping‑force range adapts for diverse board‑grade thickness variants, ensuring stable adhesion between double‑sided tape and test‑pieces. Specimen‑table parallelism is strictly controlled below 0.1 mm to eliminate fixture‑induced measuring deviation.
3. Multi‑Unit‑Selectable Intelligent Data Output Test results can be displayed and exported in kg/cm, N/m or J units. The system automatically computes absorbed impact‑energy after pendulum strike, removing manual‑calculation errors and supporting direct comparison against international‑standard limit‑values.
4. Two Human‑Machine‑Interface Options For Different‑User Needs

• KR‑417A: Intuitive push‑button keypad design, cost‑effective for routine‑production‑lab use.
• KR‑417B: Full‑colour touch‑screen operation, convenient for parameter‑modification, batch‑statistical calculation and data‑review. Both variants are fitted with built‑in thermal printer for on‑site hard‑copy test‑report output.

5. Rigid Bench‑Top Mechanical Construction Heavy‑duty stable cabinet‑body minimises vibration disturbance during high‑energy pendulum‑impact cycles. Well‑aligned pendulum‑transmission‑assembly guarantees consistent 90‑degree impact angle for excellent test‑repeatability across long‑term continuous‑operation.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Position tester on level vibration‑isolated lab bench. Power‑on unit. Cut specimens to standard 25.4 × 25.4 mm size and condition samples under specified temperature‑humidity environment. Prepare qualified double‑sided adhesive‑tape for specimen assembly. Adjust compression‑pressure and clamping‑force according to board‑thickness and applicable‑standard.
2. Specimen Assembly & Loading Bond specimen between two metal blocks using double‑sided tape. Place assembled assemblies onto the five‑position test station. Activate pneumatic compression procedure to achieve required bonding pressure and hold for specified dwell‑time.
3. Pendulum‑Impact Test Execution Release pendulum to deliver standard‑angle impact. The pendulum strikes the metal fixture, triggering Z‑direction internal delamination within paper‑board specimen. System captures residual pendulum energy and calculates energy absorbed by sample delamination. Complete sequential test for all five loaded specimens within the batch.
4. Data Review & Report Output Check ply‑bond strength readings on display. View batch‑average and deviation statistics. Print inspection‑report via integrated thermal‑printer for lab‑file‑keeping.
5. Post‑Test Tidying Remove tested specimens and used adhesive‑tape residues. Clean five‑position test‑station surface. Reset pendulum mechanism. Shut‑down power‑supply after finishing all test‑batches. Perform regular pendulum‑calibration to sustain measuring‑accuracy.
