警示帶以PE（聚乙烯）顆粒為原料，所以它的防腐性能好，可保障埋地30-50年不被分解持續起到警示作用，那決定警示帶質量的關鍵因素到底有哪些？下面燃氣管道警示帶廠家就為大家講解一下：

The warning tape is made of PE (polyethylene) particles, so its anti-corrosion performance is good, which can ensure that it will not be decomposed for 30-50 years. What are the key factors that determine the quality of the warning tape? The manufacturer of gas pipeline warning tape will explain:

先要講的是警示帶的原料PE（聚乙烯）顆粒的性能好，它無臭，，手感似蠟，具有優良的耐低溫性能（低使用溫度可達-100~-70°C），在-60℃下仍可保持良好的力學性能，使用溫度在80~110℃。化學穩定性好，能耐大多數酸堿的侵蝕（不耐具有氧化性質的酸）。常溫下不溶于一般溶劑，吸水性小，電絕緣性優良，經測試埋入地下30年不會腐爛。

The first thing to say is that the raw material PE (polyethylene) particle of the warning tape has good performance. It is odorless, non-toxic, feels like wax, and has excellent low temperature resistance (low service temperature can reach - 100~- 70 ° C). It can still maintain good mechanical properties at - 60 ℃, and the service temperature is 80~110 ℃. It has good chemical stability and can resist the corrosion of most acids and alkalis (not resistant to acids with oxidizing properties). It is insoluble in general solvents at room temperature, has low water absorption, excellent electrical insulation, and will not rot after being buried underground for 30 years.

再者就是工藝，吹膜設備均為三層共擠新設備，能保障警示帶半成品的橫向和縱向的抗撕裂強度，同時可根據技術文件有效的控制產品的厚度和寬度，不會因為超標而造成成本提高。

Moreover, the process. The film blowing equipment is a new three-layer co extrusion equipment, which can ensure the horizontal and vertical tear resistance of the warning tape semi-finished products. At the same time, the thickness and width of the products can be effectively controlled according to the technical documents, and the cost will not be increased because of the excessive standard.

后就是印刷工藝，再都的警示帶如果警示語印刷工藝把握不好，隨管道埋入地下3-5年便褪色了，那就起不到警示作用了。

Then there is the printing process. If the printing process of the warning tape in Zaidau is not well understood, it will fade after 3-5 years of being buried underground with the pipeline, which will not serve as a warning.

看完上述三條關鍵因素，大家在采購警示帶時也有了技術考核標準了，感謝大家的閱讀，以上就是本次分享的全部內容，更多內容請關注我們網站http://m.scnu-graduate.com。
