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

Embodiment 1

[0050] Nonylphenol polyoxyethylene ether 82 parts

[0051] DL malic acid 5 parts

[0052] 3 parts citric acid

[0053] 10 parts deionized water

[0054] Flavor 0.01 parts

[0055] Preparation method:

[0056] (1) Heat 10 parts of deionized water to 60-100°C, slowly add 82 parts of nonylphenol polyoxyethylene ether, and stir for 3-5 minutes;

[0057] (2) After the product in the previous step is cooled to 30-50°C, slowly add 5 parts of DL malic acid and 3 parts of citric acid into the cooled product while stirring, then stir for 10-15 minutes, and then pack it into a finished product as required .

Embodiment 2

[0059] Nonylphenol polyoxyethylene ether 70 parts

[0060] 2 parts malic acid

[0061] 1 part citric acid

[0062] 6 parts deionized water

[0063] Flavor 0.005 parts

[0064] Preparation method is the same as embodiment 1.

Embodiment 3

[0066] Nonylphenol polyoxyethylene ether 120 parts

[0067] Malic acid 10 parts

[0068] 6 parts citric acid

[0069] 20 parts deionized water

[0070] Flavor 0.005 parts

[0071] Preparation method is the same as embodiment 1.

[0072] The physical form of the present invention is a water-soluble liquid, which is different from the existing reducing agent. This water-soluble liquid is conducive to operation during use, and is convenient to add to the liquid molten metal; at the same time, it is also conducive to rapid flow and diffusion on the surface of the liquid molten metal . When in use, just pour the anti-oxidation reducing agent of the present invention directly on the liquid surface, and it will spread rapidly by itself and cover the entire liquid surface.

[0073] Anti-oxidation of the present invention, reduction principle are as follows:

[0074] 1. Cut off oxygen, thereby reducing the amount of oxidation

[0075] When the product is added to the surface of ...

Abstract

The invention discloses a water-soluble molten metal oxidation resisting and reducing agent which comprises the components of nonyl phenol polyethenoxy ether, malic acid, citric acid and water. The invention has the advantages of water solubility, good environmental performance, no halogen,convenient use, easy operation, low cost, high cost performance, remarkable and lasting effect, cleanness, simplicity,convenience and process optimization, and can simultaneously achieve the effects of oxidation resistance and active reduction and promote the improvement of the combining capacity of molten metal.

Description

technical field [0001] The invention relates to a metal anti-oxidation and reduction agent, in particular to a water-soluble molten metal anti-oxidation and reduction agent with good environmental performance and no halogen. 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 rate on the one hand, and on ...
