燃氣警示帶作為埋地石油、天然氣管道不可或缺的警示產品，在應用數年來一直沒有被替代正是因為它不錯的產品特性，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，下面就為大家講解一下：

As an indispensable safety warning product for buried oil and gas pipelines, the gas warning tape has not been replaced in the past few years because of its good product characteristics. The warning tape uses PE (polyethylene) particles as raw material, so it has good anti-corrosion performance, which can ensure that the buried oil and gas pipelines will not be decomposed for 30 to 50 years and continue to play a warning role. What are the key factors that determine the quality of the warning tape? Let's explain below:

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。

First of all, PE (polyethylene) particles, the raw material of the warning tape, have good performance. It is odorless, non-toxic, and feels like wax. It 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 ℃. Good chemical stability, resistant to most acids and alkalis (not resistant to oxidizing acids). It is insoluble in general solvents at normal temperature, has low water absorption, excellent electrical insulation, and will not decay after being buried underground for 30 years.

再者就是工藝，我廠的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. Our film blowing equipment is a three-layer co-extrusion new equipment, which can guarantee the transverse and longitudinal tear resistance of the warning tape semi-finished products, and can effectively control the thickness and width of the product according to the technical documents, without causing cost increase due to exceeding the standard.

再然后就是印刷工藝，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 Zaidi is not well grasped, it will fade after being buried in the ground for 3-5 years along with the pipeline, and it 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，我公司成立多年來為多條眾點管線提供了警示帶，到現在開挖時還能保持警示帶的各項性能指標，得到了客戶的高度認可。您有需求就來我們網站http://www.scnu-graduate.com進行咨詢吧！
