新浪新聞資訊，記者報道：環氧煤瀝青防腐鋼管在應用中有哪些注意事項呢：油漆的配比要嚴格按照要求來進行、涂裝施工及保養。油漆應存放在干燥、通風、陰涼處，嚴禁雨淋暴曬、和接近火源；運輸應遵守易燃運輸的安全規定。為確保涂層質量，施工時，如遇風沙、雨、雪、霧天氣時應停止防腐層的露天施工。當環境溫度低于-10℃高于40℃或相對濕度高于80％時，不宜施工。涂裝時下一道涂層應在上一道涂層實干后涂裝，如果丙烯酸聚氨酯漆漆膜完全固化，應打毛后再涂裝下一道。涂裝后的設備應在防腐層完全固化后交付使用，未固化的涂層應防止雨水浸淋。冬季施工每道涂層需徹底干燥，層間重涂時間比夏季施工要求長。環氧煤瀝青防腐管技術質量標準；環氧煤瀝青防腐管技術質量指標符合《埋地鋼質管道環氧煤瀝青涂層技術標準》，鋼管防腐等級符合設計要求，各種防腐等級的防腐結構符合規定。三布五油防腐鋼管是環氧煤瀝青鋼管中的一種，主要有環氧樹脂+煤焦油瀝青+填料制成的涂料在鋼管表面上用玻璃布作為加強涂敷而成的防腐層。

隨著市政建設的不斷發展,對管道的施工技術和施工質量也提出了越來越高的要求,對于埋地鋼管的外防腐方面,目前我們已淘汰了石油瀝青外防腐,統一采用環氧煤瀝青防腐鋼管。采用環氧煤瀝青防腐鋼管的優點是: 1.兼具煤焦瀝青耐水性好、防銹性能優良、耐細菌侵蝕的優點,又具環氧樹脂漆膜堅韌、附著力好、機械強度高的特點。 2.成膜涂層的耐化學介質、電絕緣性能、耐微生物侵蝕、耐海水性能等都較穩定。特別是吸水率小,不受微生物侵蝕遠遠超過石油瀝青。 3.使用壽命較長。為了正確對埋地鋼管采用環氧煤瀝青防腐鋼管,保證防腐層質量,延長埋地鋼管的使用壽命,應嚴格按照以下要求施工: 一、施工技米要求 1.鋼管表面處理。一般鋼管表面都有氧化皮、銹蝕、油污、灰塵等,若不經處理,會直接影響涂層的附著力,為了保證防腐層的使用壽命,鋼質表面處理需采用噴砂除銹,使基本面能達到SaZ(l/2)級(用肉眼看表面有明顯的毛紋),除完銹應在6h內涂刷底漆。 2.涂底漆。涂底漆可采用滾刷或漆刷,涂刷底漆要求盡量薄涂,一般為30拜m一5如m,應注意漆膜均勻不得漏涂。

With the continuous development of municipal construction, the construction technology and quality of pipelines are also put forward higher and higher requirements for buried steel pipe external anti-corrosion, we have eliminated petroleum asphalt external anti-corrosion, the unified use of epoxy coal tar pitch anti-corrosion steel pipe. The advantages of using epoxy coal tar pitch anticorrosive steel pipe are as follows: 1. It has the advantages of good water resistance, rust resistance and bacterial corrosion resistance of coal tar pitch, and has the characteristics of tough epoxy resin film, good adhesion and high mechanical strength. 2. The chemical resistance, electrical insulation, microbial corrosion resistance and seawater resistance of the film-forming coating are stable. In particular, the water absorption rate is small, and is free from microbial erosion. 3. longer service life. In order to correctly adopt epoxy coal tar pitch anticorrosive steel pipe for buried steel pipe, ensure the quality of anticorrosive coating and prolong the service life of buried steel pipe, the following requirements should be strictly followed: 1. Construction technology requirements 1. Steel pipe surface treatment. Generally steel pipe surface has oxide scale, rust, oil stains, dust, etc. If not treated, it will directly affect the adhesion of the coating. In order to ensure the service life of the coating, steel surface treatment needs to use sandblasting rust removal, so that the basic surface can reach SaZ (l/2) level (with the naked eye to see the surface has obvious hair lines), rust removal should be finished in 6 hours primer. 2. priming. Primer can be used rolling brush or paint brush, paint primer required to be as thin as possible, generally 30 bye m-5 such as m, should pay attention to uniform film should not be missed.
