A Simple Identification Method For Motorcycle Helmets Quality
Good quality helmets not only have a fixed logo, but the following content: Product name, factory name, site, trademarks, product types, product models, specifications and production license number. Poor quality helmets markings are incomplete.
Good quality helmets, material selection of FRP or ABC Engineering Plastics, Goggles for PC plastic velvet, according to national standards also undergo hardening treatment to increase strength. The poor quality of the helmets, the selection is recycled or ordinary plastic, and without hardening treatment.
Simple Identification Method:
(1 with nails on the general hard object of the eye, do not leave scratches of good quality.)
2 The description of the deformation of the shell with a slight impact is liepin.
(3 good quality helmets, the protective layer uses non-toxic harmless material, the size standard, the granule is very fine (generally no more than 3 millimeters), can absorb the collision energy best, enhances oneself intensity. The worst-quality helmets, the protective layer of foam coarse particles, can not effectively absorb the impact energy, forced extrusion.
Riding a motorcycle in Japan will have a good habit of wearing a helmets, even a pupil riding a bicycle will consciously wear a helmets. The function of the helmets is to protect the head of the rider, and to prevent rain and snow in the cold winter, to avoid the dust in the air or flying objects into the eyes, the heat dissipation function of the Han is also very good.
At present, our country's production of motorcycle protection helmets style features many, only from the function can be divided into full helmets (fully closed type), half helmets (ordinary), special custom-made helmets (such as with an electronic sober type). The classification of vehicles can be divided into ordinary motorcycle helmets, children's helmets, safety helmets, women's helmets, sports helmets, racing helmets, commercial helmets, the types of cross-country competitions with helmets and competition-type helmets. The former belongs to the general design, the design request is lower, the latter belongs to the special design, the design request is higher.
