Introduction to the advantages of automotive plastic fuel tanks
Abstract: For fuel economy, the weight of the car body will be strictly controlled, and the fuel tank is not immune, and the plastic fuel tank can provide more volume under the same conditions.
Compared with iron fuel tanks, plastic fuel tanks have the following significant advantages:
1. Light weight: For fuel economy, the weight of the body will be strictly controlled, and the fuel tank will not be spared, and the plastic fuel tank can provide more volume under the same conditions.
2. Strong anti-corrosion ability: the plastic fuel tank will not produce some impurities due to corrosion, so it can ensure the cleanliness of the fuel supply pipeline, reduce the impurities entering the engine, and increase its service life.
3. High plasticity: Plastic fuel tanks are usually manufactured by blow molding. In theory, they can be made into any complicated shape, which can save space in addition to the volume of fuel.
4. Material stability: Because it is a high molecular polymer, its chemical properties are relatively stable, so the plastic fuel tank has a long service life.
5. High safety: It has certain flame retardancy, and will not explode due to high temperature expansion. The shell can also maintain good elasticity. It will not be severely deformed after a slight impact. At the same time, it will not generate electricity during friction or impact. Sparks lead to fuel.
6. Low production cost: This is the most attractive advantage for automakers. Not only is the processing technology of plastic fuel tanks relatively simple, but also the cost of raw materials is not high. At present, most plastic fuel tanks use resin composite materials, even scrapped products can be crushed. recycle.
Plastic fuel tanks have so many advantages, is it useless for metal fuel tanks? In fact, it is not. In addition to the common iron fuel tanks, there are also aluminum fuel tanks and aluminum-magnesium alloy fuel tanks. Among them, aluminum alloy fuel tanks still have a certain market position. The aluminum alloy fuel tank itself has good corrosion resistance, and can not rust for many years when used properly, and it is lighter than iron material, and the silver appearance that comes with it is simple, which simplifies spraying. In terms of safety, aluminum alloy itself has better extensibility and is not easy to break in collision. It is also convenient to defrost in winter.
Metal fuel tanks are mostly formed by welding, and the welded parts are prone to breakage when impacted. In extreme cases, it will cause fuel leakage. Plastic fuel tanks are mostly blow molded at one time. Engineering plastics have better impact resistance and deformation and cracking resistance. This is also an important reason why engineering plastic fuel tanks are gradually replacing metal fuel tanks. But this does not mean that a metal fuel tank is equivalent to unsafe.
