地埋式警示帶作為埋地石油、天然氣管道不可或缺的警示產(chǎn)品,在應用十數(shù)年來一直沒有被替代正是因為它出色的產(chǎn)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(xù)起到警示作用,那決定警示帶質(zhì)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 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(yōu)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℃?;瘜W穩(wěn)定性好,能耐大多數(shù)酸堿的侵蝕(不耐具有氧化性質(zhì)的酸)。常溫下不溶于一般溶劑,吸水性小,電絕緣性優(yōu)良,經(jīng)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 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.
再者就是工藝,大部分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(jù)技術文件有效的控制產(chǎn)品的厚度和寬度,不會因為超標而造成成本提高。
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 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,我公司成立十年來為我國多條眾點管線提供了警示帶,供貨到現(xiàn)在足有10年之久,到現(xiàn)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。
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.
