Example Embodiment

[0080] The present invention is a slag-reducing degreasing and chromizing agent compatible and pollution-reducing spray system in the aluminum industry, which fully understands the production confusion of aluminum processing enterprises. The spraying pretreatment process with huge environmental protection pressure is a new process born after an unprecedented systematic research.

[0081] 1. Quantitative and qualitative analysis of degreasing and chromating stable and compatible agents.

[0082] 1. Qualitative and quantitative analysis of each component of degreasing liquid

[0083] In the prior art, the acid degreasing liquid is generally selected from sulfuric acid, phosphoric acid, nitric acid, hydrochloric acid, hydrofluoric acid, sodium fluoride, ammonium fluoride, ammonium bifluoride and an appropriate amount of surfactant for degreasing. The quantitative and qualitative analysis of each component is as follows:

[0084] Sulfuric acid: Sulfuric acid is the basic compone...

Abstract

The invention discloses an oil removing and chromizing chemical agent compatibility and pollution reduction sprinkling system for slag reducing of the aluminum industry. An oil removing groove, a first non-flowing water washing groove set, a chromizing groove, a second non-flowing water washing groove set, a sprinkling groove and a drainage groove are included; an aluminum material sequentially passes through the oil removing groove, the first non-flowing water washing groove set, the chromizing groove, the second non-flowing water washing groove set, the sprinkling groove and the drainage groove; the oil removing groove and the second non-flowing water washing groove set are both communicated with the first non-flowing water washing groove set; oil removing liquid exists in the oil removing groove; chromizing liquid exists in the chromizing groove; the oil removing liquid and the chromizing liquid are mutually compatible; a first pump is further included; the sprinkling groove and thedrainage groove are both communicated with the second non-flowing water washing groove set through the first pump; and the first pump is used for pumping water in the sprinkling groove and the drainage groove into the second non-flowing water washing groove set. We pay attention to compatibility of selected components on the oil removing liquid for the first time. The oil removing and chromizingchemical agent compatibility and pollution reduction sprinkling system for slag reducing of the aluminum industry achieves waste water and waste slag zero emission during spraying and chromizing treatment and production water saving.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a degreasing and chromizing agent compatible and pollution-reducing spray system for reducing slag in the aluminum industry. Background technique [0002] Aluminum and aluminum alloys have the advantages of excellent processing performance, good corrosion resistance, beautiful surface, high recovery rate, etc., and have been widely used in construction, transportation, machinery, electric power and other industries. In recent years, the trend of expanding the application of aluminum by replacing steel with aluminum has become more obvious . The aluminum processing industry is a traditional industry, and it is a sunrise industry full of vitality. According to statistics, the per capita annual consumption of aluminum in developed countries in Europe and the United States is more than 32kg, while the per capita consumption in my country is only about 13kg, which is ...
