1、 Features of PE warning protection board:

1.  PE警示护板接纳的PE质料生产
，并添加了增韧增强耐老化等质料
，使用寿命长
，抗拉伸强度高柔韧性好
，耐侵蚀抗攻击力高
，在受到外力时能起到很好的

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警示护板警示字体接纳耐高温酸碱质料
，警示字体上覆有pp

，可有用起到警示作用
，在不明地下情形施工挖掘时能有用的阻止不须要的破损和爆发意外爆炸的重大损失。

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.

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

1、通俗警示带虽然本钱低廉
，但起不到

；さ叵鹿艿赖南宰判Ч
，PE警示护板前期本钱高于通俗警示带但现实使用效果显着优于通俗警示带。

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、现在海内修建垃圾治理不规范
，修建垃圾随处可见
，在不明地下情形开挖时很容易把水泥板混同于修建垃圾一起挖走
，以是起不到有用的

；す艿雷饔
，水泥板体积大重量高
，运输和施工不利便且施工效率低。PE警示护板重量轻运输及施工利便。在不明地下情形施工开掘时会把PE警示护板拉出来
，因PE质料有很好的拉伸强度纵然被拖出也不宜断裂
，且通过PE警示护板上的显着警示语言
，很容易相识到地下管道埋藏情形从而能有用地

；さ叵鹿艿啦槐黄扑。水泥板本钱和PE警示护板成内情当但施工用度高
，总体本钱要高于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 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.
