2、重防腐涂料的判斷方法

    根據國家標準、行業標準、企業標準等的要求,看它是否具備特殊性。判斷方法大致如下:

    2.1涂層的厚度大

    一般的防腐涂料的厚度以μm計,而重防腐涂料則以mm計。如:

    2.2可在惡劣環境下工作

    一般的管道防腐涂料常在空氣中工作,而重防腐涂料常在腐蝕性介質的長期直接浸泡中工作。例如:埋地管道的防腐層常在地下水(淡水或海水)、地下酸、堿或鹽的強腐蝕性介質浸泡下工作;同時,還受地下厭氧菌和植物根莖的侵蝕。原油儲罐的內防腐則需要在含有酸性介質和大量水的原油中工作。上述的工作環境比一般的防腐層所處的環境要惡劣的多,這是重防腐的工作性質決定的,也是一般的防腐技術不能達到的。

    2.3涂層的使用壽命長

    據國內外大量實踐經驗和資料表明,重防腐涂料的使用壽命一般在15-20年。例如,濱七聯-濱二首站的污水輸送管道,工作了20多年,涂層為改性石油瀝青,厚度7mm,火花檢漏20000V。

    4.1涂料的配套性

    重防腐涂料也和其他涂料一樣存在著相互之間的配套問題,總結如下:

    (1)石油瀝青涂層的補口補傷和大修,可以用石油瀝青(熱施工),也可以用聚氨酯石油瀝青冷涂料(常溫施工),但切不可用玻璃鱗片涂料和環氧煤瀝青;

江西快3    (2)BOLILINPIANCENGDEBUKOUBUSHANGHEDAXIU,HUANYONGBOLILINPIANTULIAO(CHANGWENSHIGONG),BUKEYONGSHIYOULIQINGHEJUANZHILENGTULIAO;

     (3)防靜電涂層的補口補傷和大修,可采用防靜電涂料(常溫施工),以保證涂層良好的導電性和穩定性,不可用石油瀝青和聚氨酯涂料進行修補。

    (4)任何一種新的儲罐內防腐可以選用防靜電涂料、玻璃鱗片涂料、酚醛環氧漆、厚漿型環氧重防腐涂料中的任何一種。
