Problems solved by technology

Its biggest technical problem is that pure n-bromopropane will decompose when heated to dozens of degrees to produce HBr (hydrogen bromide), forming HBr acid to corrode industrial metals. Due to the technical blockade and monopoly of Europe and the United States, the product profits are huge, and the survival of domestic enterprises is relatively low. difficulty

Description

technical field [0001] The invention relates to a cleaning agent, in particular to an environment-friendly cleaning agent. Background technique [0002] In recent years, with the continuous improvement of people's living standards and industrial technology, various metal products, electronics, precision industry and other products have been widely used in industrial production and people's daily life, and the market demand is relatively large. During the processing and after forming of various metal products, the surface needs to be cleaned, and the surface and depressions of metal products, electronics, precision industry and other products need to be cleaned. In the cleaning process, various types of cleaning agents need to be used. When the cleaning agent washes the dirt on the surface of the object, it can change the surface activity of water and improve the decontamination and descaling effect. Compared with general cleaning agents, environmentally friendly cleaning a...
