1. PE警示护板采用的PE材料生产，并添加了增韧增强耐老化等材料，使用寿命长，抗拉伸强度高柔韧性好，耐腐蚀抗冲击力高，在受到外力时能起到很好的保护及警示作用。

1. The PE warning board is made of high-quality PE material and added with materials such as toughening and aging resistance. It has a long service life, high tensile strength, good flexibility, corrosion resistance, and high impact resistance. It can provide good protection and warning when subjected to external forces.

2. PE警示护板警示字体采用耐高温酸碱材料，警示字体上覆有pp保护膜，保护警示字体不被破坏，可有效起到警示作用，在不明地下情况施工挖掘时能有效的避免不必要的破坏和发生意外爆炸的重大损失。

2. The warning font of the PE warning board is made of high-temperature resistant acid and alkali materials, and is covered with PP protective film to protect the warning font from damage. It can effectively serve as a warning and avoid unnecessary damage and significant losses caused by accidental explosions during excavation in unknown underground conditions.

二、PE警示保护板和普通警示带及水泥板的效果对比

2、 Comparison of the effects of PE warning protection board, ordinary warning tape, and cement board

1、普通警示带虽然成本低廉，但起不到保护地下管道的明显效果，PE警示护板前期成本高于普通警示带但实际使用效果明显优于普通警示带。

1. Although ordinary warning tapes are low-cost, they do not have a significant effect on protecting underground pipelines. PE warning boards have a higher initial cost than ordinary warning tapes, but their actual use effect is significantly better than ordinary warning tapes.

2、目前国内建筑垃圾管理不规范，建筑垃圾到处可见，在不明地下情况开挖时很容易把水泥板混同于建筑垃圾一起挖走，所以起不到有效的保护管道作用，水泥板体积大重量高，运输和施工不方便且施工效率低。PE警示护板重量轻运输及施工方便。在不明地下情况施工开掘时会把PE警示护板拉出来，因PE材料有很好的拉伸强度即使被拖出也不宜断裂，且通过PE警示护板上的明显警示语言，很容易了解到地下管道埋藏情况从而能有效地保护地下管道不被破坏。水泥板成本和PE警示护板成本相当但施工费用高，总体成本要高于PE警示护板。

2. At present, the management of construction waste in China is not standardized, and construction waste can be seen everywhere. When excavating in unknown underground conditions, it is easy to mix cement boards with construction waste and excavate them together, so it cannot effectively protect pipelines. Cement boards have a large volume and high weight, making transportation and construction inconvenient and low construction efficiency. PE warning boards are lightweight, easy to transport and construct. When excavating under unknown underground conditions, the first step is to pull out the PE warning shield, as the PE material has good tensile strength and should not break even if pulled out. Moreover, through the obvious warning language on the PE warning shield, it is easy to understand the buried situation of the underground pipeline, which can effectively protect the underground pipeline from damage. The cost of cement board is equivalent to that of PE warning board, but the construction cost is high, and the overall cost is higher than that of PE warning board.
