摘要:
針對服役溫度達到100 ℃以上的熱力管道腐蝕問題,研究了管道運行工況和腐蝕機理,在此基礎上采用一種新型的耐高溫涂料,開發出一種耐高溫內防腐熱力管道,并對其防腐層附著力、耐化學腐蝕性、耐高溫高壓等性能進行了對比試驗。結果表明,這種耐高溫內防腐熱力管道具有良好的光潔致密性,涂層與基材結合緊密,附著力超過7 MPa;試樣在10%H2SO4溶液、10%NaOH溶液以及3%NaCl溶液浸泡720 h均未發生起泡,表面光亮;涂層玻璃轉化溫度達到142.78 ℃、熱分解起適溫度達到319.4 ℃條件時,仍具有良好的熱穩定性。開發的耐高溫內防腐熱力管道,在國內首次批量應用于某供熱系統,為高溫熱力管道內防腐提供了新的解決方案。
Abstract:
In view of the corrosion problem of thermal pipeline with service temperature above 100 ℃, the operation condition and corrosion mechanism of pipeline were studied. A new high temperature resistant coating was adopted to develop a high temperature resistant internal anticorrosion thermal pipeline, and the adhesion, chemical corrosion resistance, high temperature and high pressure resistance of the anticorrosion coating were compared. The results showed that the high temperature resistant internal anticorrosion thermal pipeline has good smoothness and compactness, the coating is closely bonded with the base material, and the adhesion exceeds 7 MPa. The samples soaked in 10% H2SO4 solution, 10% NaOH solution and 3% NaCl solution for 720 h did not foam and the surface was bright. When the conversion temperature of coating glass reached 142.78 ℃and the suitable temperature for thermal decomposition reached 319.4 ℃, the coating transition still has good thermal stability. The thermal pipe with high temperature resistant and internal anticorrosion has been applied in a heating system for the first time in China, which provides a new solution for internal anticorrosion of high temperature resistant thermal pipe.
