Shang Zun Ink Rub Resistance Tester InkT-10-26

Overview

The Shang Zun InkT-10-26 Ink Rub Resistance Tester is an electromechanical instrument engineered for quantitative assessment of surface rub resistance in printed and coated materials. It operates on the principle of controlled linear reciprocating motion between a standardized rubber friction pad and a flat specimen under defined load and speed conditions. The device replicates real-world mechanical abrasion encountered during handling, packaging, transportation, and end-use exposure—enabling objective evaluation of ink adhesion, coating integrity, and substrate surface stability. Designed for routine quality control laboratories and R&D facilities, the InkT-10-26 delivers repeatable, operator-independent test outcomes aligned with internationally recognized physical testing methodologies.

Key Features

• Precise speed control across a continuous range of 20–115 cycles per minute, with selectable preset speeds at 21, 43, 85, 100, and 106 cycles/min for rapid method standardization.
• High-resolution timing circuitry ensures speed accuracy within ±1 cycle/min, critical for inter-laboratory comparability and regulatory audit readiness.
• Intuitive 7-inch capacitive touchscreen interface supports multi-language operation, real-time status monitoring (incremental/decremental count, elapsed time, remaining cycles), and storage of up to 20 user-defined test protocols.
• Automated test termination with digital display of final cycle count, pass/fail indication (if threshold criteria are configured), and summary statistics including average cycle count to failure (when used with optional endpoint detection accessories).
• Modular friction pad system accommodates three standardized thickness options (3 mm, 4 mm, 8 mm) to vary contact pressure and simulate differing application forces without hardware modification.
• Robust aluminum alloy chassis and low-vibration stepper motor drive ensure mechanical stability over extended test sequences and minimize measurement drift.

Sample Compatibility & Compliance

The InkT-10-26 is validated for use with rigid and semi-flexible planar substrates up to 5 mm in thickness, including offset- and flexo-printed paperboard, BOPP and PET films, pressure-sensitive labels, UV-cured coatings, and water-based gravure inks. Its test platform accepts specimens measuring 50 mm × 100 mm, conforming to dimensional requirements specified in GB/T 7706 (Chinese national standard for gravure ink rub resistance), TAPPI T830 (rub resistance of printing inks on paper and paperboard), and ASTM D5264 (standard practice for evaluating rub resistance of printed materials). The instrument’s mechanical design and calibration traceability support compliance with ISO/IEC 17025 laboratory accreditation requirements when operated within documented SOPs and maintained per manufacturer-recommended intervals.

Software & Data Management

While the InkT-10-26 operates as a standalone unit with embedded firmware, its data output architecture supports integration into broader laboratory information management systems (LIMS) via RS-232 serial interface (optional USB-to-serial adapter available). All test logs—including date/time stamp, selected speed, total cycles executed, operator ID (manually entered), and pass/fail flag—are stored internally with non-volatile memory retention exceeding 10,000 records. Audit-trail functionality meets GLP and GMP documentation expectations: no record can be edited or deleted; only appended entries are permitted. Export formats include CSV and plain-text log files compatible with Excel, Minitab, and statistical process control (SPC) platforms.

Applications

• Quality assurance of ink formulation batches prior to commercial release.
• Comparative evaluation of primer/coating adhesion performance across substrate types (e.g., uncoated vs. clay-coated paper).
• Validation of curing parameters (UV dose, thermal dwell time) in digital and analog printing processes.
• Supplier qualification testing for contract packaging vendors supplying pharmaceutical blister foils or food-grade laminates.
• Root-cause analysis of print marring observed during high-speed packaging line trials.
• Supporting technical documentation for ISO 9001 internal audits and customer-facing material specifications.

FAQ

What standards does the InkT-10-26 directly support?
It is mechanically and functionally compliant with GB/T 7706, TAPPI T830, and ASTM D5264. Full conformance requires adherence to specimen preparation, environmental conditioning (23°C ±2°C, 50% RH ±5%), and operator training per each standard’s Annexes.
Can the instrument be calibrated traceably to national standards?
Yes—calibration certificates issued by accredited third-party labs (e.g., CNAS-certified providers in China or A2LA-accredited labs in North America) are available upon request. The device includes built-in diagnostic routines for speed and cycle counter verification.
Is remote firmware update capability supported?
Firmware updates are performed locally via USB flash drive using Shang Zun’s official utility software; no cloud connectivity or internet dependency is required for security and regulatory compliance.
What maintenance intervals are recommended?
Lubrication of linear guide rails and inspection of rubber pad wear are advised every 5,000 test cycles or semiannually—whichever occurs first. Replacement pads are supplied with lot-specific certification of durometer (Shore A 60±5) and dimensional tolerance.
Does the tester meet electrical safety requirements for export markets?
The unit complies with IEC 61010-1:2010 for laboratory equipment and carries CE marking (EU Declaration of Conformity available). Input voltage auto-sensing enables seamless operation on 120 V/60 Hz (North America) and 230 V/50 Hz (EU/APAC) networks.
