金属表面的清理喷丸处理

金属表面的清理喷丸处理通过将加速能量传递至喷丸介质，以冲击或磨蚀方式去除工件表面的异物。清理任务的范围广泛，异物的种类与数量决定了所需的喷丸能量，进而影响喷丸介质及喷丸系统的选择。对于去除铸件表面的型砂及其他残留物，通常需采用高能量、强穿透力的喷丸，最经济的方式是通过涡轮或离心轮喷丸机，并使用较大的圆形喷丸介质。清理喷丸处理的子类别除砂、除氧化皮、除锈及去除涂层等工艺在众多工业领域广泛应用，尤其在重工业、钢结构及铸造行业，此类设备规模庞大。有关各工艺的详细信息，请参阅专题章节。

清洁、除油或脱脂

高效金属脱脂的洁净之道

金属脱脂与清洗——工业清洗工艺必知要点

在众多工业制造过程中，常使用油脂、冷却润滑剂及脱模剂等介质，即使采用现代微量润滑技术，这些介质仍会残留在工件表面。

在拉深、冲压、精冲及切削加工（铣削、车削）等工艺中，金属工件需借助油脂、乳化液等介质进行加工。在后续处理前，必须通过去油（如使用无溶剂清洗剂丙酮）去除这些残留物。压铸件因脱模剂污染，需通过去油剂/清洗剂进行优化预处理，以确保涂装质量。切削加工工件（如铣削件）因冷却润滑剂污染，可通过精加工光整工艺进行清洗，为后续加工做好准备。

超越清洁本身

对于此类钢材及有色金属工件的清洗，精加工光整工艺及其设备是理想选择。作为溶剂替代方案，该工艺通常不含异丙醇，且通过机械运动辅助水基清洗，能有效去除油脂与污染物。多样化的清洗产品可满足不同应用需求，尤其对有色金属，去除污染物后可显著改善表面质量。

若需对表面进行喷丸处理，则必须确保其不含乳化液、油脂、污染物及水分。在喷丸技术中提及的“清洗”通常指“经典清洗喷丸工艺”，如清砂、除氧化皮、除锈及去除涂层。此时重点并非去除润滑油或油脂，而是清除金属表面的锈蚀、型砂、氧化皮、涂层及附着物（如污垢或灰尘），以还原纯净基材。这些工艺是喷丸技术的核心应用，广泛应用于铸造、钢结构及原钢生产等金属加工行业

Industrial parts cleaning using mass finishing and shot blasting

One of the key advantages of mass finishing is that multiple processing steps – such as cleaning, degreasing, deburring, and polishing – can always be performed within a single process, either simultaneously or in sequence, in the same system. This saves both time and cost while consistently delivering uniform, reproducible results. As an alternative to solvents, this type of degreasing and cleaning is typically free of isopropanol. Instead, the mechanical motion generated by the relative movement of the grinding media and workpieces actively enhances the cleaning performance of the consumables. The extensive range of cleaning products offers numerous advantages across a wide variety of applications. Non-ferrous metals in particular benefit from the removal of contaminants, resulting in a significantly improved surface appearance.

When the term "parts cleaning" is used in the context of shot blasting, it typically refers to the conventional blast cleaning methods such as de-sanding, descaling, rust removal, and decoating. In these cases, the focus is not on removing lubricants and oils, but rather on stripping rust, molding sand, scale, and coatings from metal surfaces of all types, as well as removing adherent deposits such as dirt and dust. The goal is to expose the bare base material. These processes represent a core area of shot blasting technology and are widely adopted solutions across many industries that process metal parts – including foundries, structural steel fabrication, and raw steel production.

Depending on the cleaning task at hand, different cleaning media, nozzles, and systems are employed. The right combination of cleaning technology, cleaning agents, and process parameters determines both the results achieved and the overall cost-effectiveness of the operation.
