Why is plastic tank better than iron tank, mainstream gasoline tank contrast?
Comparison of single automotive plastic fuel tank and the six layer of automobile plastic fuel tank: six layers of plastic tank and single plastic tank is compared in the following aspects: the performance is consistent with the 1. light weight; 2. acid and alkali corrosion resistance, no rust; 3. can make full use of body space, to go back and play after the impact will not produce permanent deformation; 4. in the process of friction or impact does not produce spark and explosion accidents; 5. advantages of long service life.
Moreover, the plastic fuel tank has many advantages, such as long service life, low production cost and so on. All of the above in the automotive industry has been widely acknowledged that the plastic fuel tank to replace iron tank, multi-storey tank instead of single tank is the mainstream direction of the development of the car, the car power -- the United States, will bid farewell to the iron tank accident, car type 95% tank are plastic tank; the EU 91% tank are plastic tank; is in the iron tank power -- Japan, they have clearly realized that the iron tank hidden, and has begun the development of bulk production of plastic fuel tank. The use of plastic fuel tank models: the old model - santhara, Jetta, Beverly plastic tank; new models - Audi A6, A4, Bora, golf, Passat B5, POLO, GOL, Citroen, Senna, Picasso, Elysee, Tianjin TOYOTA Vios, Changan Ford and other car models are used in plastic tank; Hainan Mazda has also will change the original use of the iron tank into a plastic tank.
Comparison of metal and plastic fuel tank for automobile fuel tank: plastic fuel tank compared with iron tank, has the following advantages of -1. light weight (general iron tank wall thickness of at least 1.2mm, plastic tank average wall thickness is 4mm, the density of iron is 7.8, plus the iron tank outer surface to do anti rust treatment, such the density reached 8, while the plastic fuel tank material density of HDPE is about 0.95, so a tank of equal volume of iron is 2.5 times heavier than the plastic tank), acid / alkali corrosion, no rust, can make full use of space, the body can not meet the impact after springback permanent deformation, friction or not in the process of impact produce electric spark caused by explosion.
