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

Embodiment 1

[0049]

[0050] Preparation method:

[0051] (1) Heat 10 parts of deionized water to 60-100°C, slowly add 82 parts of Tween-80, and stir for 3-5 minutes;

[0052] (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, and after stirring for 10-15 minutes, pack it into a finished product as required.

Embodiment 2

[0054]

[0055] Preparation method is the same as embodiment 1.

Embodiment 3

[0057]

[0058] Preparation method is the same as embodiment 1.

[0059] 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.

[0060] Anti-oxidation of the present invention, reduction principle are as follows:

[0061] 1. Cut off oxygen, thereby reducing the amount of oxidation

[0062] When the product is added to the surface of the molten metal, it will spread rapidly and cover the entire liquid surface, forming a protective film to block the contact between the molten metal and oxygen, ther...

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...
