| 炭黑含量： Carbon black content: 炭黑含量是滴灌带产品重要的材料质量指标，其含量直接影响滴灌带的耐老化性能，老化状态会影响滴灌带产品的全部性能指标，炭黑含量过高或过低都不合格。 Carbon black content is an important material quality index of drip irrigation belt products. Its content directly affects the aging resistance of drip irrigation belt. Aging status will affect all performance indicators of drip irrigation belt products. Too high or too low carbon black content is not qualified. 拉伸性能： Tensile properties: 拉伸性能是指滴灌带在铺设或之后的移动调整过程中，对人为牵拉的受力抵抗性。拉伸性能不合格会导致滴灌带铺设时牵拉受力后产生迷宫变形，直接对滴灌带造成了功能性破坏，从而导致通水后的流量不均，也就直接破坏了滴灌带的节水控水能力。拉伸性能实际上也受炭黑含量的影响。 Tensile properties refer to the resistance of drip irrigation belts to artificial pull during laying or after moving adjustment. Unqualified tensile properties will lead to labyrinth deformation when drip irrigation belts are laid under pulling force, which directly destroys the functionality of drip irrigation belts, resulting in uneven flow after water passage, thus directly destroying the water-saving and water-controlling capacity of drip irrigation belts. The tensile properties are also affected by the content of carbon black. 流量均匀度：流量均匀度也称为流量偏差，是滴灌带产品的基本功能性，是考核滴灌带产品质量最为重要的指标。流量均匀度不合格易造成作物供水不均匀，影响作物经济产量，也同样无法实现节水的基本作用。 Flow uniformity: Flow uniformity, also known as flow deviation, is the basic function of drip irrigation belt products and the most important index to evaluate the quality of drip irrigation belt products. Unqualified flow uniformity can easily cause uneven crop water supply, affect crop economic yield, and also can not achieve the basic role of water saving. |
