The application of nitrogen gas purification equipment in the automotive industry The first point is to strengthen the protection and comfort of the driving part of the vehicle tire in the application of automobiles. Nitrogen is almost inert, two-atomic gas, and its chemical properties are very impressive. Gas molecules are bigger than oxygen molecules, are not easy to swell and contract, and deformation is rugged and small, and its permeation of the tire walls is about 30 to 40 percent slower than air, which can maintain the stable tire pressure, the stability of traveling on the tire, and ensure the comfort of driving; Nitrogen has a low audio conductivity, equivalent to 1 / 5 of ordinary air, and the use of nitrogen can significantly reduce tire noise and quietness. Avoid breaking tyres and running without air. Jet tires are the number one killer in road traffic accidents. According to statistics, 46 percent of traffic accidents on highways are caused by tire failure, and a tire blowout alone accounts for 70 percent of all tire accidents. When a car travels, the tire temperature will increase due to friction with the ground. Especially when traveling at high speed and when braking urgently, the gas temperature inside the tire will rise rapidly, and the tire pressure will increase rapidly, so there may be a tire blowing. High temperatures cause tire rubber to age, fatigue strength to decline, and tire surface wear to a great extent, which is also an important factor for tires to break. 

Compared with general high pressure air, high purity nitrogen gas, because it is oxygen-free and almost no water, does not contain oil, has a low thermal expansion coefficient, low heat conductivity, slow heating, reduces the rate of heat gathering of the tire, is non-flammable and does not ignite, so it can greatly reduce the chance of exploding the tire. Nitrogen gas purification equipment extends tire service life After the use of nitrogen, the stable volume of tire pressure is small, which greatly reduces the probability of irregular friction of the tire, such as crown grinding, shoulder grinding, bias grinding, and the service life of the tire. The aging of rubber is caused by the oxidation of oxygen molecules in the air. After aging, its strength and elasticity decline, and it will crack, which constitutes one of the reasons for the shortening of tire service life. Nitrogen diversion equipment can clean oxygen, sulphur, and sulfur in the air to the maximum extent possible. Oil, water and other impurities usefully reduce the oxidation of the lining of the tyre and the corrosion of the rubber, do not corrode the metal rim, extend the service life of the tyre, and greatly reduce the rust of the rim. In addition to the above, we must further reduce the energy consumption to achieve an environmentally friendly life. The lack of tire pressure and the increase of roll resistance after heat will constitute an increase in fuel consumption when the car travels; In addition to maintaining a stable tire pressure, nitrogen can maintain a steady tire pressure. In addition to prolonging the reduction of tire pressure, its dry, oil-free and water-free properties, low heat conductivity, slow heating, reduces the temperature increase when the tire travels, and the tire deformation small grip driving, reduces roll resistance, and then reaches the intention of reducing fuel consumption.
