| 中文摘要: |
| 分析引起车用汽油硫含量、未洗胶质和溶剂洗胶质含量超标的原因，系统综述加油机胶管的使用现状、相关标准、低渗透型胶管研发背景、结构、技术优势。使用低渗透型加油机胶管代替现用普通加油机胶管可以解决汽油流经胶管引起硫含量和胶质含量超标的问题，在防止大气污染方面具有积极意义，具有广阔的市场应用前景。 |
| 英文摘要: |
| The reasons that the sulfur content of gasoline for vehicle，the unwashed and solvent-washed gum content excessed the standard limits were analyzed，and the current application state of the fuel dispenser hose with low-permeability，related standard，development background，and its structure and technical advantages were reviewed.The application of the fuel dispenser hose with low-permeability to replace the existing common fuel dispenser hose could solve the problems that the sulfur content and gum content caused by gasoline flowing through the hose excessed the standard limits, had a positive significance in preventing air pollution，and had a wide market application prospect. |
