1. 清潔

1. Cleaning

溶劑、乳劑用于濟南鍍鋅鋼管表面的清潔，可以去除油脂、污垢、流平劑等類似有機物質，但不能去除鋼材表面的銹、垢、助焊劑等，只能作為防腐蝕生產中的輔助手段。

Solvent and emulsion can remove grease, dirt, leveling agent and other similar organic substances, but can not remove rust, dirt and flux on the steel surface, so they can only be used as auxiliary means in anti-corrosion production.

2. 噴(拋)銹

2. Spraying (throwing) rust

噴霧(Pao光)除銹是由大功率電機,高速旋轉的葉片和葉片噴灑,這樣等磨料磨具鋼沙、鋼球、金屬碎片和礦物質可以噴到鋼管的表面下離心力的影響。是的，它不僅能完全去除銹、氧化、粉塵，而且在粗糙的沖擊和摩擦的影響下達到所要求的平均粗糙度。

Spray (Pao) rust is sprayed from the blades and blades of high speed motors with high speed rotation, so that abrasive, steel balls, metal fragments and minerals can be sprayed to the surface of the steel tube under the influence of centrifugal force. Yes, it can not only completely remove rust, oxidation and dust, but also achieve the required average roughness under the influence of rough impact and friction.

噴涂(拋光)、除銹后，可延長濟南鍍鋅鋼管外表面的物理吸附效果，提高防腐涂層與管道外表面的機械結合效果。因此，噴霧除銹是一種理想的除銹方式。噴丸處理一般主要用于管道內部和外部處理，噴丸處理主要用于管道表面處理。

After spraying (polishing) and derusting, the physical adsorption effect on the outer surface of Jinan galvanized steel pipe can be extended, and the mechanical bonding effect between the anti-corrosion coating and the outer surface of the pipe can be improved. Therefore, spray rust removal is an ideal way to remove rust. Shot peening is generally used for internal and external treatment of pipeline, and shot peening is mainly used for surface treatment of pipeline.

3.工具除銹

3. Tool derusting

首先，用鋼絲刷對濟南鍍鋅鋼管表面進行拋光，去除疏松或拉長的氧化皮、鐵銹、焊渣等。手動工具的除銹能力可達SA2級，電動工具的除銹能力可達SA3級。如果鋼表面附著強氧化鐵垢，除銹效果不理想，無法獲得耐腐蝕結構所需的錨固深度。

Firstly, the surface of Jinan galvanized steel pipe was polished with wire brush to remove loose or elongated oxide scale, rust and welding slag. The derusting ability of hand tools can reach SA2, and that of electric tools can reach SA3. If strong iron oxide scale is attached on the steel surface, the rust removal effect is not ideal, and the anchorage depth required for corrosion-resistant structure cannot be obtained.

4. 酸洗

4. Pickling

一般采用化學法和電解法，可用于酸洗后的噴砂、濟南鍍鋅鋼管防腐的化學酸洗、氧化皮、銹、舊涂層的去除和除銹。化學清洗可能不可避免地看起來干凈和粗糙，但錨定模式是淺的，容易受到污染。

It can be used for sandblasting after pickling, chemical pickling for anticorrosion of Jinan galvanized steel pipe, removal and derusting of oxide scale, rust and old coating. Chemical cleaning may inevitably look clean and rough, but the anchoring mode is shallow and vulnerable to contamination.
