1、 Features of PE warning protection board:

1.  PE警示護板采用的PE材料生產，并添加了增韌增強耐老化等材料，使用壽命長，抗拉伸強度高柔韌性好，耐腐蝕抗沖擊力高，在受到外力時能起到很好的保護及警示作用。

1. The PE warning guard 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 impact resistance, and can provide good protection and warning when subjected to external forces.

2.  PE警示護板警示字體采用耐高溫酸堿材料，警示字體上覆有pp保護膜，保護警示字體不被破壞，可有效起到警示作用，在不明地下情況施工挖掘時能有效的避免不必要的破壞和發生意外爆炸的重大損失。

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

二、PE警示保護板和普通警示帶及水泥板的效果對比

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

1、普通警示帶雖然成本低廉，但起不到保護地下管道的明顯效果，PE警示護板前期成本高于普通警示帶但實際使用效果明顯優于普通警示帶。

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

2、目前國內建筑垃圾管理不規范，建筑垃圾到處可見，在不明地下情況開挖時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護管道作用，水泥板體積大重量高，運輸和施工不方便且施工效率低。PE警示護板重量輕運輸及施工方便。在不明地下情況施工開掘時會把PE警示護板拉出來，因PE材料有很好的拉伸強度即使被拖出也不宜斷裂，且通過PE警示護板上的明顯警示語言，很容易了解到地下管道埋藏情況從而能有效地保護地下管道不被破壞。水泥板成本和PE警示護板成本相當但施工費用高，總體成本要高于PE警示護板。

2. At present, the management of construction waste in China is not standardized, and construction waste can be seen everywhere. When excavating under unknown underground conditions, it is easy to mix cement boards with construction waste, which cannot effectively protect pipelines. Cement boards have a large volume and high weight, making transportation and construction inconvenient and low construction efficiency. The PE warning board is lightweight and easy to transport and construct. When excavating under unknown underground conditions, the PE warning shield will first be pulled out, 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 burial situation of the underground pipeline and 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.
