濟南鍍鋅方管在我國經濟中發揮著重要的作用，它的應用領域也較為廣泛，受天氣和環境的影響，長期使用濟南鍍鋅方管表面也會出現生銹，如何去除銹蝕，下面章丘市鴻祥泰就為大家介紹一下。

Jinan galvanized square tube plays an important role in China's economy, its application field is also very wide, affected by the weather and environment, long-term use of Jinan galvanized square tube surface will also appear rust, how to remove rust, the following Zhangqiu hongxiangtai for you to introduce.

去除濟南鍍鋅方管銹斑的4個有用方法

Four useful methods to remove rust spots of Jinan galvanized square pipe

1.為使濟南鍍鋅方管達到理想的除銹效果，應根據合金管的表面硬度、原始腐蝕程度、所需的表面粗糙度和涂層類型來選擇磨料。應采用單層環氧樹脂、雙層或三層聚乙烯涂層。為了達到理想的除銹效果，應采用鋼砂和鋼丸的混合磨料。因為鋼砂可以強化鋼材表面，鋼砂可以腐蝕鋼材表面。

1. In order to achieve the ideal derusting effect of Jinan galvanized square pipe, the abrasives should be selected according to the surface hardness, original corrosion degree, required surface roughness and coating type of the alloy pipe. Single epoxy, double or triple polyethylene coating shall be used. In order to achieve the ideal derusting effect, the mixed abrasive of steel sand and steel shot should be used. Because steel sand can strengthen steel surface, steel sand can corrode steel surface.

   
   

2.除銹等級:對于常用的環氧、乙烯、酚醛等防腐涂料的施工工藝，一般要求是使表面達到接近白色等級。實踐證明，該除銹等級可以清除幾乎所有的氧化皮、鐵銹等污物，完全滿足防腐層與濟南鍍鋅方管管的附著力要求，但不除銹噴淋除銹工藝可以使質量達到接近白色水平，成本較低。

2. Derusting grade: for the construction process of commonly used epoxy, ethylene, phenolic and other anti-corrosion coatings, the general requirement is to make the surface close to the white grade. Practice has proved that this derusting grade can remove almost all the scale, rust and other dirt, and fully meet the adhesion requirements of the anti-corrosion coating and Jinan galvanized square pipe, but the non derusting spray derusting process can make the quality close to the white level, and the cost is low.

3.噴霧治療前,可以去除表面的油脂和規模合金管和管可以通過加熱爐預熱到40-℃保持表面干燥,因為表面不含油脂和其它污垢,可提高除銹的效果。另外，表面干燥也有利于鋼丸、鋼砂、鐵銹和氧皮的分離，所以會使表面除銹后更加干凈。

3. before spray treatment, the grease and scale can be removed. The alloy tube and tube can be pre heated to 40- C through the heating furnace to keep the surface dry, because the surface does not contain grease and other dirt, which can improve the effect of rust removal. In addition, the surface drying is also conducive to the separation of steel shot, steel sand, rust and oxygen skin, so it will make the surface cleaner after rust removal.

4.為了獲得一個更好的統一的清潔度和粗糙度分布,磨料顆粒大小和比例的設計是非常重要的,因為濟南鍍鋅方管太大粗糙度很容易導致防腐涂料稀釋在錨線的高峰期,因為錨線太深,很容易形成泡沫的過程中防腐,這嚴重影響防腐涂料的性能。

4. in order to get a better uniform cleanliness and roughness distribution, the design of abrasive particle size and proportion is very important, because the roughness of Ji'nan galvanized square tube is very easy to cause the anticorrosive coating to dilute at the peak of anchor line, because the anchor wire is too deep, and it is easy to form foam to prevent corrosion, which seriously affects the performance of anticorrosive coating.
