目前,为柴油机配备的柴油胶管所用原材料普遍为丁腈橡胶。丁腈橡胶耐油性能好,但耐臭氧老化性能较差。而改用橡塑合金材料,即使用丁腈橡胶与聚氯乙烯混合物,可使其耐臭氧老化性能明显提高。国家《内燃机燃油系统输送常规液体燃油用纯胶管和橡胶软管》标准(GB10542-1989)和工程机械行业《高
At present, the raw materials used for diesel hose equipped with diesel engines are generally nitrile rubber. Nitrile rubber oil resistance, but poor resistance to ozone aging. The switch to rubber alloy material, that is, the use of nitrile rubber and polyvinyl chloride mixture, can make it significantly improved ozone aging performance. National “internal combustion engine fuel system for conveying conventional liquid fuel with pure rubber hose and hose” standard (GB10542-1989) and construction machinery industry "high
