箱体由铝板焊接而成。为提高其防腐性能,板材在焊接之前要进行阳极化处理。而阳极化膜是焊接的一大障碍。因此,临焊之前必须用人工把焊区的阳极化膜层仔细地打磨干净,但因阳极化膜坚硬结实,打磨起来很费劲,而且工人的劳动强度加大,产生的粉尘和噪音对环境又造成了严重的污染。后来,又采用氯丁橡胶可剥涂料来保护焊缝区不进行阳极化,但又出现了以下的新问题:
The box is welded by aluminum plate. In order to improve its anti-corrosion properties, the plate should be anodized before welding. The anodized film is a major obstacle to welding. Therefore, before welding, the anodized layer of the soldering area must be carefully polished and polished manually. However, due to the hard and firm anodized film, it is laborious to polish and the labor intensity of the worker is increased. The dust and noise produced are environmentally friendly Caused serious pollution. Later, the use of neoprene peelable coating to protect the weld zone is not anodized, but there are the following new problems:
