Spray:The most convenient way is to buy on the market for helmets designed to use anti-bacterial deodorant spray, spray on a regular basis as long as a spray, you can achieve the effect of anti-bacterial deodorant, but because of safety helmets will be directly exposed to our skin, natural ingredients must be chosen before the after-effects will not occur.2. The sun:Each week the helmet upside down on sun exposure for three hours, using the sun's ultraviolet rays kill the bacteria inside, do not need to spend money very environmentally friendly, less able to eliminate dead space within the dust and oil.3. Wipe:Use a clean cotton cloth stained detergent, wipe the external and wind helmet mirror, exterior cleaning and maintenance for the helmets are effective, but not the joint helmet liner only way to do wipe clean.4. Brush and vacuum cleaner:The toothbrush will not have dried, brush the dust except helmet liner to see chip, then vacuum these foreign body aspiration.

Commonly used material is ABS (Industrial Plastics) and glass fiber. Good helmet carbon fiber making a useful, but expensive; 2, buffer layer (foam core) - the main function of the buffer layer is the absorption of external impact. If the hard shell helmet without buffer layer, in the event external shocks, external force through the hard shell directly on the head so that his head hurt. Therefore, the thickness of the buffer layer, the merits of the decision of the helmet material buffering capacity. Buffer layer mainly styrene foam material; 3, inner layer - the main role is to enhance the comfort when wearing, generally made of soft flannel;Technical standards for motorcycle helmets key indicators include: 1, helmet goggles visible light transmission, impact resistance; 2 The strength properties of helmet wearing; 3, helmet collision energy absorption performance; 4, helmet puncture-resistant properties.
