Brief introduction: ZHY type automatic scratch instrument in accordance with ISO 1518, BS 3900, ASTM D 5178 and ASTM D 5178 standard requirements. Nick instrument can test the product surface scratch resistance of coating, such as coil paint, tin printing ink, paint, automobile surface coating. Scratch instrument is suitable for the light of a single or composite coating surface scratch resistant coating performance evaluation, to a certain weight under spherical steel needle piercing coating or spherical steel needle piercing of maximum weight to evaluation of coating coating scratch resistant ability. Scratch test instrument with a 1 mm diameter of hemispherical scriber, slowly contact surface under test, draw a treaty 10 cm long scratches. According to different test purpose of load and load, can be observed in different degree of penetration, traces from the surface to penetrate completely. Motor driver sample contact with scriber gently, row needle in the sample, to the finish after automatic stop. Scriber contact with metal substrate by a volt meter to identify, when measured sample coating was scratched, ammeter display is energized. Technical indicators: Motor: 60 w, 220 v, 50 hz Farmar weight: 1000 g / 500 g / 200 g each, 50 g / 100 g each second The scriber ball diameter: 1 mm Run trip: 100 mm Speed: 30 to 40 mm/SEC Dimension: 380 * 300 * 180 mm (length * width * height) Instrument net weight: 30 kg
