● What Nitrogen is?
is almost inert nitrogen diatomic gases, chemically inert electrode, the gas molecules is larger than oxygen molecules, heating or cooling is not easy, small deformation amplitude, its penetration rate is slower than the tire sidewall air at about 30 to 40 percentage, can remain stable tire pressure, improving the running stability of the tire, to ensure driving comfort; audio low conductivity nitrogen, equivalent to 1/5 of the ordinary air, nitrogen gas can effectively reduce the tire noise, improve the running quiet degrees.
● prevent puncture and lack of air grind line
is the number one killer tire road traffic accidents, according to statistics, there are 46 on the highway percentage of traffic accidents due to tire failure caused by a puncture which accounted for 70 percentage of the total tire accident. When cars, tire temperature can be raised due to friction with the ground, especially at high speeds and the emergency brake, the gas inside the tire temperature rises rapidly, tire pressure surge, so there may be a puncture. The high temperatures cause tire rubber aging, fatigue strength decreased, severe tread wear, but also important factors could puncture. Compared with the general high-pressure air, high purity nitrogen and oxygen-free because the oil does not almost no water, a low coefficient of thermal expansion, low thermal conductivity, slow heating, reducing the heat accumulating speed of the tire, and then co-like nor non-natural characteristics, it is possible to greatly reduce the chance of a puncture.
● extend tire life
After the nitrogen gas, the air pressure stable small volume change, irregular tire greatly reduces the possibility of friction, such as crown grinding, the shoulder grinding, partial wear, improve the service life of the tire; the aging of rubber is caused by the oxidation of oxygen molecules in the air, its strength and elasticity after aging decreases, and there cracking phenomenon, when one of the causes of the shortened life of the tire. Nitrogen separation device greatly limits exclusion of air oxygen, sulfur, oil, water and other impurities, oxidation degree and effectively reduce the tire innerliner rubber layer is etched, which will not corrode the metal rim, the tire is extended life, but also greatly reduce the rim rusty condition.
● reduce fuel consumption, environmental protection
After the heated inadequate tire pressure increases rolling yin force, will result in increased fuel consumption when driving the car; and nitrogen in addition to maintaining a stable tire pressure , tire pressure decrease delay beyond which no oil without dryingThe aqueous, low thermal conductivity, the temperature rise characteristics of slow, reducing the running temperature of the tire is improved, and deformation and the like to improve grip, rolling resistance is reduced, thus to decrease fuel consumption. US parties made a comparative experiment nitrogen filled tires and filling the air, the experimental statistical results showed that nitrogen filling than air-filled tires run more than 26 percent mileage. Nitrogen-filled tires can be inflated by the design of the tire pressure, the car can achieve fuel consumption indicators design time. Experiments show that nitrogen than air-filled tire tire percentage saving 2-10. Effective in reducing air pollution. Brazilians practiced, nitrogen filled tires with a fifty thousand kilometers still need qi. Nitrogen tire more resistant to wear than the pneumatic tire, it is not reached before breakage of the tire tread loss index, tires filled with nitrogen gas mileage than the average run air-filled tire 48 illustrating the percentage of multiple
