Easily degraded molten metal oxidation resisting reducing agent

Abstract

The invention discloses an easily degraded molten metal oxidation resisting reducing agent. The reducing agent comprises the following components of: Tween-80, malic acid, citric acid and water. The reducing agent has the advantages of easy degradation, high water solubility, high environmental protection performance and no halogen. The reducing agent also has the advantages of convenient use, easy operation, capability of playing the role in resisting oxidation and actively reducing at the same time, assistant improvement on binding ability of the molten metal, low cost, high cost performance, obvious effect, sustained effect, simple and convenient cleaning and optimized process.

Description

technical field [0001] The invention relates to a metal anti-oxidation reducing agent, in particular to a molten metal anti-oxidation reducing agent which is good in environmental protection performance, does not contain halogen and is easy to degrade. Background technique [0002] In industrial production, it often involves the process of melting a metal or alloy to combine or adhere to another metal. Since most metals will be oxidized in contact with oxygen, such as tin slag (SnO and SnO) produced in a static tin furnace or a dynamic wave furnace 2 ) is one of the most common examples of metal oxidation in industry. In a high-temperature environment, especially in a molten state, the oxidation of the metal (or alloy) will be more severe, and a layer of oxide will soon be formed, and the more it gathers. In the process of adhesion and bonding of molten metal and other metals, the molten metal must be continuously flowed and circulated, which will intensify the oxidation r...

AI Technical Summary

Problems solved by technology

[0014] A: Diffusion is not fast enough and requires vigorous stirring

[0015] B: The viscosity of the oily substance is too high, and it often adheres to the workpiece, causing product pollution and making it difficult to clean

[0016] C: Its viscous residue and molten metal mixture, in the molten metal flow cycle, adhere to the equipment components, resulting in blockage and blockage of the equipment circulation channel, causing inconvenience to equipment maintenance

[0017] D: sediment, sticking to equipment parts, similar to resin-type hard substances, very difficult to clean

It is very inconvenient to maintain and clean the equipment. In the long run, it will definitely damage the equipment.

[0018] E: Inorganic acids that are not easy to degrade, contain phosphorus, etc. are highly polluting to the environment, and are not environmentally friendly. The halogen contained in them will adhere to the workpiece, causing the product to absorb moisture and oxidize easily
