燃气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不错的产品特征，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 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。
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. 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 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，我公司建设多年来为多条众点管线提供了警示带，到现在开挖时还能坚持警示带的各项性能指标，获得了客户的高度认可。您有需求就来我们网站
