地埋式警示带作为埋地石油、天然气管道不可或缺的警示产品,在应用十数年来一直没有被替代正是因为它出色的产品特性,警示带以PE(聚乙烯)颗粒为原料,所以它的防腐性能好,可保障埋地30-50年不被分解持续起到警示作用,那决定警示带质量的关键因素到底有哪些,下面就为大家讲解一下:
As an indispensable safety warning product for buried oil and natural gas pipelines, the buried warning tape has not been replaced for more than ten years. Precisely because of its excellent 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 warning tape, Let me explain it for you:
先要讲的是警示带的原料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℃下仍可保持良好的力学性能,使用温度在80~110℃。化学稳定性好,能耐大多数酸碱的侵蚀(不耐具有氧化性质的酸)。常温下不溶于一般溶剂,吸水性小,电绝缘性优良,经测试埋入地下30年不会腐烂。
First of all, PE (polyethylene) particles, the raw material of the warning tape, have good properties. They are odorless, non-toxic, and feel like wax. They have excellent low-temperature resistance (low use temperature can reach - 100 ~ - 70 ° C). They can still maintain good mechanical properties at - 60 ° C, and the use temperature is 80 ~ 110 ° C. It has good chemical stability and can resist most acid-base corrosion (not oxidizing acid). It is insoluble in general solvents at normal temperature, with small water absorption and excellent electrical insulation. It will not rot after being buried underground for 30 years.
再者就是工艺,大部分的吹膜设备均为三层共挤新设备,能保障警示带半成品的横向和纵向的抗撕裂强度,同时可根据技术文件有效的控制产品的厚度和宽度,不会因为超标而造成成本提高。
Furthermore, the process. Most of the film blowing equipment are new three-layer coextrusion equipment, which can ensure the transverse and longitudinal tear strength of the semi-finished warning tape. At the same time, the thickness and width of the product can be effectively controlled according to the technical documents, and the cost will not be increased due to exceeding the standard.
后就是印刷工艺,再都的警示带如果警示语印刷工艺把握不好,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 warning tape is not well controlled in the printing process, it will fade after being buried underground with the pipeline for 3-5 years, which will not serve as a warning.
看完上述三条关键因素,大家在采购警示带时也有了技术考核标准了,感谢大家的阅读,我公司成立十年来为我国多条众点管线提供了警示带,供货到现在足有10年之久,到现在开挖时还能保持警示带的各项性能指标,得到了客户的高度认可。
After reading the above three key factors, we also have technical assessment standards when purchasing warning tapes. Thank you for reading. Our company has provided warning tapes for many multi-point pipelines in China in the past ten years since its establishment. It has been 10 years since the first supply. Now, we can maintain all performance indicators of warning tapes during excavation, which has been highly recognized by customers.
The above is all the content shared this time. Please pay attention to our official website for more information http://www.binzhouhengtong.com , to answer more questions in use for you, so that you can better use the warning tape for construction.
