铝板生产厂家是如何提高铝板预处理工作的质量

来源:

  铝产品广泛应用于汽车、建筑等行业,提高铝产品的质量是企业生存的根本,铝材料在空气中非常不稳定,容易产生用肉眼也难以识别的氧化膜。由于铝加工技术的不同方法,如铸造成型,或直接压盘剪切的延迟,或精细机械加工和成型,或通过不同工艺热处理后形成或焊接,表面将呈现不同的状态,不同程度的污垢或标志,因此在预处理过程中必须根据实际情况选择表面预处理过程的方法。
  Aluminum products are widely used in automobile, construction and other industries. Improving the quality of aluminium products is fundamental to the survival of enterprises. Aluminum materials are very unstable in the air and easy to produce oxide films which are difficult to identify with the naked eye. Due to the different methods of aluminium processing technology, such as casting, delayed direct pressing shear, fine mechanical processing and forming, or forming or welding after heat treatment by different processes, the surface will present different states, varying degrees of dirt or marks, so surface pretreatment must be selected according to the actual situation in the pretreatment process. Process approach.

  预处理过程需要注意的是,并非所有的表面加工后,铸件不加工表面厚氧化层铸造过程中形成的,有些人仍与砂夹,此时应先加工或喷砂方法,请先删除原来的氧化膜的部分,又或碱洗处理后,只有用这种方法不仅可以删除所有未加工的部分原始氧化层,并可避免加工零件公差尺寸的变化。

  In the pretreatment process, it should be noted that not all the surface is processed, but some castings are still sandwiched when the oxide layer on the surface is not machined. At this time, the original oxide film should be removed first, or after alkali washing. Only this method can remove all the unprocessed oxide layer. Some of the original oxide layer can avoid the change of tolerance dimension of machined parts.

  精密机械零件在预处理过程中需要注意的问题:细加工件时自然氧化膜表面的第一代,更容易,但脂肪体重,特别是在孔和周围,这些工件必须首先由有机溶剂清洗,如果与碱性清洁油腻的重量很难删除所有,不仅直接和精密机械加工表面不能碱腐蚀很长一段时间,结果会影响工件表面粗糙度和宽容合作,最终可能成为一种浪费。
  Precision machinery parts in the pretreatment process should pay attention to the following issues: the first generation of natural oxide film surface is easier when fine-processing parts, but fat weight, especially around holes, these parts must first be cleaned by organic solvents, if with alkaline clean greasy weight is difficult to delete all, not only directly and precisely machined tables. Surface cannot be corroded by alkali for a long time. The result will affect the surface roughness and tolerance of the workpiece, which may eventually become a waste.
