1. Quality requirements for luminous safety helmets:

Luminous helmets must not have defects such as bubbles, pinholes, wrinkles, unevenness, defects, bruises, scars, burrs, poor curing, etc., but they can be repaired. The perimeter and surface of the helmet must be free from burrs and delamination. The internal surface is flat, and no defects are allowed.

  1. Performance test:

Impact performance: The 5.5 kg spherical steel hammer was dropped freely from a height of 1 meter and hit the top of the glow in the dark helmet. The impact force on the head model could not exceed 4900N, and no cracks greater than 50mm were allowed on the surface of the helmet. The rope at the chin is not allowed to break.

Puncture resistance: The steel cone with a weight of 3 kg is free-falling from a height of 1 meter (hardness 45, taper 60 °, radius 0.5mm), and the luminous safety helmet is impacted. The steel cone cannot contact the head model.

Side pressure test: Load 424N pressure on the side of the luminous helmet, and the deformation of the helmet is less than 40mm. After the pressure is released, the degree of deformation of the helmet is less than 15mm.

Flame retardant performance: Put 70 # gasoline into gasoline torch and burn the helmet. After ten seconds, remove the flame. The helmet should be extinguished by itself within 5s. The test ambient temperature is 10-30 ℃.

Antistatic performance: According to the requirements of GB 2812-1989 test the surface resistance of the helmet.

The glow in the dark powder absorbs light energy under the sunlight or incandescent light. In the dark state, the absorbed light energy is emitted in the form of glow and added to the manufacturing process of the helmet to ensure that the helmet is in a dark environment. Under glow. It can be widely used in transportation, construction, mining, and other industries, and plays an important role in protecting personal safety and improving the safety of night operations and use in the dark.
