警示带作为埋地石油、自然气管道不可或缺的警示产品，在应用数年来一直没有被替换正是由于它很是好的产品特征，警示带以PE（聚乙烯）颗粒为质料，以是它的防腐性能好，可包管埋地30-50年不被剖析一连起到警示作用，那决议
燃气警示带质量的要害因素究竟有哪些，下面就为各人解说一下。
As an indispensable safety warning product for buried oil and gas pipelines, the warning tape has not been replaced for several years because of its very good product characteristics. 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 gas warning tape.
先要讲的是警示带的质料PE（聚乙烯）颗粒的性能好，它无臭，，手感似蜡，具有优良的耐低温性能（低使用温度可达-100~-70°C），在-60℃下仍可坚持优异的力学性能，使用温度在80~110℃�；裙绦院�，能耐大大都酸碱的侵蚀（不耐具有氧化性子的酸）。常温下不溶于一样平常溶剂，吸水性小，电绝缘性优良，经测试埋入地下30年不会腐败。
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.
再者就是工艺，我厂的吹膜装备均为三层共挤新装备，能包管警示带半制品的横向和纵向的抗撕裂强度，同时可凭证手艺文件有用的控制产品的厚度和宽度，不会由于超标而造成本钱提高。
Moreover, the process. All the film blowing equipment in our factory are new three-layer coextrusion 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 exceeding the standard.
然后就是印刷工艺，再都的警示带若是警示语印刷工艺掌握欠好，随管道埋入地下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 being buried in the ground for 3-5 years, which will not serve as a warning.
看完上述三条要害因素，各人在采购警示带时也有了手艺审核标准了，谢谢各人的阅读，本公司建设多年以来为我国多条众点管线提供了警示带，获得了客户的高度认可。您有相关的需要就来我们网站
