This instrument is designed and manufactured in accordance with GB/T 5480-2017, “Test Methods for Mineral Wool and Its Products,” and can be used to determine the slag ball content in glass wool and its products, slag wool, rock wool and their products, as well as aluminosilicate wool and its products. By exploiting the differences in gravitational and drag forces experienced by slag balls and fibers when they are suspended in an aqueous medium, the slag balls and fibers are separated; the slag ball content in the mineral wool is then quantified through drying, sieving, and weighing.
Determination of slag ball content in refractory fiber wool and its products, as well as non-fibrous materials. This equipment can analyze the slag ball content in glass wool and its products, slag wool, rock wool and their products, and aluminosilicate wool and its products. Please read the instruction manual carefully before use. Technical specifications of the JLD-105 Mineral Wool Slag Ball Content Analyzer: Glass rotor flowmeter: 0–200 mL/min Separation cylinder: inner diameter 80 mm, height 380 mm Fiber collector: 138 × 98 mm Slag ball collector: 138 × 98 mm Plastic water tank: 210 × 140 mm Overall dimensions of the slag ball content analyzer: 390 × 185 × 570 mm.
I. Product Overview This instrument is designed to assess the impact resistance of reflective films for use in manufacturing and quality‑control inspection, based on the principle of free fall of a steel ball. It is developed and manufactured in accordance with the impact‑resistance test method specified in GB/T 18833‑2002 “Reflective Films for Road Traffic Signs” of the People’s Republic of China, and complies with JT/T 686‑2007 “Impact‑Resistance Tester for Reflective Films.” II. Instrument Structure The impact‑resistance tester for reflective films consists of an upper platen, support columns, a base, and an impact ball, among other components. III. Main Technical Parameters Steel ball mass: 450 ± 4.5 g Steel ball drop height: 250 mm
