采用金属清洗剂清洗金属表面油污,改善了清洗劳动条件,节省了大量清洗用油,经济效益显著。因此,近几年发展很快。为了使这项新技术健康发展,合理地选用金属清洗剂是关键,为此我们总结了金属水基清洗剂的技术试验方法。一、试液、试片的制备: 试液制备:液体清洗剂充分摇匀后取样(不少于500毫升),固体或膏状清洗剂取三个不同部位(不
The use of metal cleaning agent to clean the metal surface oil, improved cleaning labor conditions, saving a lot of cleaning oil, significant economic benefits. Therefore, it has developed rapidly in recent years. In order to make the new technology develop healthily, it is the key to select the metal cleaner rationally. Therefore, we summarize the technical test method of metal water-based cleaning agent. First, the test solution, the preparation of the test piece: Preparation of the test solution: After the liquid cleaning agent is fully shaken and sampled (not less than 500 ml), solid or paste detergent take three different parts
