環球新聞資訊，9月8日報道：環氧粉末防腐鋼管【勝倉管業 袁經理18903175665 QQ1623133043】FBE環氧粉末先在流化床內充分流化，然后通過靜電噴，使粉末顆粒帶負電，均勻地豁附在接地的經預熱的鋼管表面。對于少量擴散的粉末，可通過回收系統回收，不會造成粉塵污染。管道防腐中有一種涂料叫做重防腐環氧粉末涂料，它還可以稱作為熔結環氧粉末，【勝倉管業 袁經理18903175665 QQ1623133043】國外一般都簡稱為FBE，*早是開發于20世紀50年代，60年代實現了工業化生產，經過這么多年的不斷完善，此涂料已經發展較為成熟。現在大部分防腐鋼管都在使用重防腐環氧粉末涂料.環氧粉末防腐鋼管的使用范圍之大，已經遍布全世界各地，從力陸地到海洋，從平原到山地，河流，湖泊，從西伯利亞草原到非洲沙漠，從美洲大陸到中東海灣，這些都有熔結環氧粉末的應用實例。我國zui大工程“西氣東輸”就采用的是環氧粉末防腐鋼管，使得重防腐環氧粉末涂料在我國有了長足的發展。重防腐熔結環氧粉末涂料按用途可分為：管道內噴涂用粉、管道外噴涂用粉、石油鉆管用粉，以及三層結構防腐用粉.雙層熔結環氧粉末防腐鋼管
環氧粉末防腐鋼管【勝倉管業 袁經理18903175665 QQ1623133043】主要用于油田腐蝕嚴重的集輸管道、污水處理及回注管道上，以延長管道的壽命，為石油開發和生產提供了保障，通常口徑較小、距離較短。以減阻、節能為目的的內涂敷技術，在我國西氣東輸管道工程中首次應用。天然氣管道的減阻內涂技術是一項經濟效益顯著的商新技術，雖然各國的參數取值不盡相同，但結論卻是一致的，認為初期投入的成本將會有幾倍的收益，管徑越大、線路越長、輸氣量越大，收益就越高環氧粉末是一種熱固性、無毒涂料，固化后形成高分子量交聯結構涂層，具有優良的化學防腐性能和較高的機械性能，尤其耐磨性和附著力zui佳。【勝倉管業 袁經理18903175665 QQ1623133043】該涂料為%固體，無溶劑，無污染，粉末利用率可達%以上，十埋地鋼質管道的優質防腐涂料，環氧粉末防腐鋼管在燃氣管道、地埋管道、供排水管道、南水北調工程中起到了重要作用溶解環氧粉末外涂層是近年來發展起來的新型防腐層，FBE涂層有單層和雙層兩種。所謂FBE涂層一般指單層溶解環氧涂層。單層FBE涂層采用專用的溶解環氧粉末涂料作為成膜材料，采用靜電噴涂工藝涂敷環氧粉末涂料，一次成膜。這種環氧粉末涂料是一種熱固性涂料，由固態環氧樹脂，、【勝倉管業 袁經理18903175665 QQ1623133043】固化劑及多種助劑經混煉和粉末加工而成，鋼管在噴漆前先經過拋丸處理和中頻預熱，在采用靜電噴涂方法將環氧粉末涂料噴涂在加熱的鋼管表面上，融粘結在鋼管表面，固化成涂層。FBE涂層一般為一次成膜結構。FBE涂層有對對鋼鐵粘結力強、膜完整性好、耐陰既剝離、耐土壤應力和耐磨損、涂敷操作簡單、無污染、涂層抗擊和抗彎曲性能好、耐溫性高等優點，在國外得到了廣泛應用。FBE涂層可用于工作溫度為~攝氏度的鋼制埋地管道或水下管道設施的外防腐。【勝倉管業 袁經理18903175665 QQ1623133043】
FBE epoxy powders are fluidized in a fluidized bed and then electrostatically sprayed to make the powders charged negatively and evenly attached to the surface of the grounded preheated steel pipe. For a small amount of diffused powder, it can be recovered through the recovery system without causing dust pollution. There is a kind of coating called heavy-duty anti-corrosion epoxy powder coatings, it can also be called fused epoxy powder, [Shengcangguan manager 18903175665 QQQ1623133043] foreign generally referred to as FBE,* was developed in the 1950s, the 1960s to achieve industrial production, after so many years of continuous improvement, This coating has developed relatively mature. Most corrosion-resistant steel pipes now use heavy-duty epoxy powder coatings. The use of epoxy powder coatings has spread all over the world, from land to sea, from Plains to mountains, rivers and lakes, from the Siberian grasslands to the African deserts, from the American continent to the Middle East Gulf. Application example of epoxy powder. The epoxy powder anticorrosive steel pipe is used in the West-East Gas Pipeline Project of Zui in China, which makes the heavy-duty anticorrosive epoxy powder coatings have a great development in China. Heavy anticorrosive fused epoxy powder coatings can be divided into: powder for internal spraying of pipelines, powder for external spraying of pipelines, powder for oil drilling pipes, and powder for three-layer anticorrosive structure. Dual-layer fused epoxy powder anticorrosive steel pipes
Epoxy powdered anticorrosive steel pipe is mainly used in gathering and transporting pipelines, sewage treatment and reinjection pipelines with serious corrosion in oil fields to prolong the service life of pipelines and provide a guarantee for oil development and production. Usually the diameter is small and the distance is short. The internal coating technology with resistance reduction and energy saving is the first application in the west east gas pipeline project in China. Drag reduction and internal coating technology of natural gas pipeline is a new commercial technology with remarkable economic benefits. Although the parameters of different countries are different, the conclusion is consistent. It is believed that the initial investment cost will be several times of the profit. The bigger the pipe diameter, the longer the line and the larger the gas transmission capacity, the higher the profit of epoxy powder is a thermosetting property. Non-toxic coatings, cured to form high molecular weight cross-linked structure coatings, with excellent chemical corrosion resistance and high mechanical properties, especially wear resistance and adhesion zui. The coating is solid, solvent-free, non-polluting, and the powder utilization rate can reach more than percent. The high-quality anticorrosive coating for ten buried steel pipelines and epoxy powder anticorrosive pipe play an important role in gas pipeline, buried pipeline, water supply and drainage pipeline, South-to-North Water Transfer Project. Epoxy powder coating is a new type of anticorrosive coating developed in recent years. There are two kinds of FBE coatings: single layer and double layer. The so-called FBE coating generally refers to the single-layer dissolved epoxy coating. The monolayer FBE coatings are made of special dissolved epoxy powder coatings as film forming materials. The electrostatic spraying process is used to coat the epoxy powder coatings. The epoxy powder coating is a thermosetting coating made of solid epoxy resin, curing agent and various additives by mixing and powder processing. The steel pipe is shot blasting and intermediate frequency preheating before spraying. The epoxy powder coating is sprayed by electrostatic spraying method. On the surface of the heated steel pipe, it is bonded to the surface of the steel pipe and solidified into a coating. The FBE coating is usually a primary film forming structure. FBE coating has been widely used abroad because of its strong adhesion to steel, good film integrity, shade peeling resistance, soil stress and wear resistance, simple operation, no pollution, good resistance to impact and bending, high temperature resistance and so on. The FBE coating can be used for external anticorrosion of steel buried pipelines or underwater piping facilities at temperatures of ~ C.
