| 我国汽车工业的快速发展给汽车配套产品——胶管带来了发展良机，如果按每辆汽车使用20m胶管计算，2005年仅新增汽车产量对胶管的需求量就在1亿m以上，加上维修用胶管，市场潜力巨大。随着汽车向高速化、高功能化和舒适性等方向发展，以及为使燃油燃烧完全而使用的电喷装置、涡轮增压装置等电器设备或部件的使用；另外，为保护环境，汽车使用无铅汽油，空调用致冷剂以R134a取代R12，汽车发动机舱变窄，温度升高等都给汽车用胶管提出更高的要求, 耐燃油、耐高温、致冷剂渗透率低、寿命长等成为汽车用胶管的发展主流。 The rapid development of China's automotive industry has brought a good opportunity for the development of rubber hose, which is a supporting product of automobiles. According to the calculation of 20 m rubber hose per vehicle, the demand for rubber hose in 2005 is over 100 million m only when the new automobile output is increased. With the maintenance rubber hose, the market potential is enormous. With the development of automobiles towards high speed, high functionality and comfort, as well as the use of electrical equipment or components such as EFI and turbocharger to make fuel burn completely, in addition, in order to protect the environment, automobiles use unleaded gasoline and refrigerants for air conditioning replace R12 with R134a, which narrows the engine compartment of automobiles. The higher the temperature, the higher the requirement of the rubber hose for automobiles. The main development trend of the rubber hose for automobiles is fuel resistance, high temperature resistance, low refrigerant permeability and long service life. |
