ZTT-920 Reflective Film Impact Tester is specially designed and produced for production, quality supervision, engineering construction and supervision units to measure the impact resistance of reflective film. It has the characteristics of reasonable structure, simple operation, wide applicability, high measurement accuracy, safe measurement and good reliability.
ZTT-920 reflective film adhesion Tester meets the requirements of my country's reflective film technical standard GB/T18833-2012.
This instrument is designed for the production and quality supervision and inspection department to measure the impact resistance of reflective film by using the principle of steel ball free fall.
Before the test of impact resistance performance, cut out a sample of 150mm*150mm, place the reflective surface on the steel plate of the equipment, 250mm above the sample, use a steel ball with a mass of 450g to fall freely, impact the center of the sample, and then Check for changes in the impacted surface of the specimen.
