Product Description

Product Description

Exothermic welding (fire mud welding, hot melt welding) The main purpose of copper oxide sheet is exothermic welding. Exothermic welding (fire clay welding, hot melt welding) is to produce liquid high temperature copper liquid and alumina residue through the chemical reaction (exothermic reaction) of aluminum and copper oxide, and use the high temperature generated by the exothermic reaction to achieve high performance Modern welding process for electric welding. 3CuO+2Al======(heating) 3Cu+Al2O3 This reaction is carried out in a high-temperature graphite mold, and the exothermic reaction process takes only a few seconds to complete.

 

Copper oxide is an inorganic substance, chemical formula CuO, is a black oxide of copper, slightly amphoteric and slightly hygroscopic. Insoluble in water and ethanol, easily soluble in acid, stable to heat, decomposes oxygen at high temperature. Copper oxide is mainly used for making rayon, ceramics, glazes and enamels, batteries, petroleum desulfurizers, pesticides, and also for hydrogen production, catalysts, green glass, etc.

Installation Instructions

Thermit welding, also known as exothermic welding, utilizes the high heat generated by the chemical reaction between aluminum and copper oxide to join metal conductors. In this process, copper oxide (CuO) plays a crucial role due to its specific properties.

Application

In exothermic welding, copper oxide serves the following important purposes:

 

1. Reactant for heat generation: Copper oxide reacts with aluminum in an exothermic reaction. The chemical equation is \(2Al + 3CuO \longrightarrow Al_2O_3 + 3Cu\). This reaction releases a large amount of heat, which can reach temperatures as high as 2500 - 3500 °C. The heat is sufficient to melt the resulting copper and the metals to be joined, enabling the welding process.
2. Provider of copper source: During the reaction, copper oxide is reduced to copper. The molten copper produced fills the weld cavity, forming a high - quality electrical and mechanical connection. It ensures a good bond between the conductors, offering excellent electrical conductivity and mechanical strength.
3. Ensurer of welding quality: Exothermic welding with copper oxide can achieve molecular - level binding between different metals. It can connect various metal combinations such as "copper - copper", "copper - zinc - coated steel", and "copper - stainless steel". This molecular - level binding improves the mechanical, electrical, and anti - corrosion properties of the weld joint, ensuring a long - lasting and reliable connection.
