The instrument is designed and manufactured in accordance with the various technical indicators stipulated in the national standard GB/T6548-1998 "Measurement of Corrugated Board Adhesive Strength". Features The sampler is beautiful in appearance, compact and reasonable in structure, and convenient to use. Applications This peeler is suitable for measuring the adhesive strength of various types of corrugated cardboard. It is a special testing instrument for cardboard samples and an optional tool for the DRK113 compression tester. Technical standard The stripper is composed of a bracket, stripper, and long and short needles. The principle is to insert the long and short needles of the sample at intervals to make relative vertical movement to completely separate the tissue paper from the core paper. The instrument meets the relevant regulations of GB/T 6548 Product parameter 1. Parallelism of the upper and lower planes of the bracket: ≤0.10 2. The upper and lower parallelism of the peeling frame: ≤0.10 3. Straightness of long and short needles: ≤0.10 4. Long and short needle diameters of type A corrugated cardboard: ∮3.5±0.1 5. Long and short needle diameters of type B corrugated cardboard: ∮2.0±0.1 6. Long and short needle diameters of type C corrugated cardboard: ∮3.0±0.1 7. E-type corrugated cardboard long and short needle diameter: ∮1.0±0.1
