Problems solved by technology

[0003] At present, the general leveling liquid on the market has insufficient cleaning performance, poor lubrication and rust resistance, and there are many residues on the board surface after leveling. It must be degreased and cleaned before subsequent tinning, which will not only waste a lot of resources and costs, but also increase waste. Environmental issues such as liquid treatment discharge

Abstract

The invention discloses a defatting-free environment-friendly tin plate tempering lubricant which comprises fatty acid, alkanolamine, an iron powder dispersant, a cleaning assistant, an oiliness agent, a corrosion inhibitor, a coalescing agent and purified water. The defatting-free environment-friendly tin plate tempering lubricant is high in cleaning property, low in residue, high in biodegradability, and friendly to people and environment.

Description

technical field [0001] The invention relates to a tinplate leveling liquid. Background technique [0002] Tinplate (commonly known as tinplate) refers to a steel plate coated with a thin layer of metallic tin on the surface. Tin plate is made by rolling low carbon steel into a steel plate with a thickness of about 0.2mm, electrolytic cleaning, annealing, leveling, edge trimming, and then cleaning, electroplating, reflowing, passivation treatment, and oiling. Finished tinplate sheet. The pretreatment (cleaning) of electroplating tin is composed of pickling, alkali washing, water washing and brushing. The purpose is to make the electroplating quality good, and the surface of the strip steel plate must be clean. Tin plate has good corrosion resistance, glossy appearance, can be further processed by welding, biting, stamping, etc., and has good printing and coloring properties, and the tin layer is non-toxic, so tin plate is widely used It is one of the most popular steel pro...
