1、前言由于丁腈橡胶(NBR)具有成本低、性能好等优点,因而在汽车橡胶件中,特别是在燃料供给系零件中占有重要地位。以燃料油管为代表,包括燃油泵隔膜、密封垫、单向阀、喷射泵阀门密封垫、化油器加速泵盖等很多重要功能件均可用此种材料制造。另外,
1, Preface As nitrile rubber (NBR) has the advantages of low cost and good performance, it occupies an important position in automobile rubber parts, especially in fuel supply parts. Representative of the fuel tubing, including fuel pump diaphragm, gaskets, check valves, jet valve seals, carburetor pump cover and many other important functions can be made with this material. In addition,
