QBJ cupping Tester | Determination of metal surface can be stretched and adhesion
Product parameters:
- Customized processing: no
- Brand: meet macros
- Model: QBJ
| Introductions: | |
QBJ cupping Tester designed according to GB/t 9753-88 and ISO 1520-73, for the evaluation of paints, varnishes and other coatings under standard test method for indentation test so that gradually it transformed its cracked or separated from the metal substrate resistance performance; The instrumental determination of metal surface can be stretched and adhesion. It is made of a 20 mm diameter steel ball, with some force, pressure plate on the unpainted side. At a certain speed (recommended: 0.2mm/s) Rotary hand wheel makes steel balls on top, and watching it through a magnifying glass plate surface. When the plate is first observed deformation and cracks immediately stops when turning the handwheel, and read out on LCD projection depth value. Main technical parameter: Manual operation, digital display, index value is 0.01mm Punch diameter: φ =20mm SAG accuracy: 0.05mm Largest convex depth: 10MM Plate size: 70mmx70mm Plate thickness: 0.30~ 1.25mm (flat deformation) Materials: the polishing plates, meet the GB/T9271 requirements With a magnifying glass/battery lights Dimension: 200x300x460mm (length x width x height) Weight: 52Kg Ordering information: QBJ---Erichsen test instrument Action steps: → Plate placed on the instrument's opening, coating side up → Medium-strength using a clamping device clamping plate → Upward direction turning the handwheel, and watching it through a magnifying glass plate surface → First crack is observed, stop turning the handwheel → Read out on the digital screen projection depth value → Display glass convex upper scale depth in 1mm increments, scale on the handwheel show every 0.05mm | |
