The water used in the production of copper enameled wires also has a variety of uses. Likewise, the requirements for water quality are also different. According to the purpose of use, the water quality requirements can be divided into: annealing furnace water sealing water, equipment cooling water, manufacturing lubricating oil water, etc.

1. Affect the quality of copper enameled wire.

In the production process of copper enameled wire, if the particles in the water remain on the copper wire, the surface of the copper wire will be uneven and small holes will appear; the pollution of ionic impurities will increase the surface charge density of the copper wire, resulting in the electrochemical performance of the oxide layer. decline. , thereby affecting its parameters. During the stretching process, these impurities are adsorbed on the copper wire and diffuse into the copper wire, affecting the surface lubrication of the copper wire, resulting in uneven local resistance and easy breakdown. Due to the effect of painting, the adhesion of the paint film is poor, resulting in a decrease in the insulation parameters of the pores. In particular, it will cause pollution due to deliquescence, and black spots will appear in climates with high humidity, which is why black spots appear on copper enameled wires. Therefore, the paint film is perforated and the moisture further intrudes, resulting in a decrease in the quality parameters of the copper enameled wire. This is also the reason for the voltage drop.

2. Influence on mechanical parts.

We know that in the transmission process of mechanical equipment, in order to ensure the continuous operation of the equipment in the case of high-speed operation and metal collision, the equipment must be cooled. If the cooling water contains a lot of impurities, it will appear: equipment pollution, corrosion, scaling, salinization, pipeline sludge, scaling, scaling. Reduced the cooling effect of the device. The equipment is damaged rapidly, the maintenance pressure increases, and the mechanical life is reduced, which will seriously affect the production power and economic benefits of the equipment.

For the blockage of the annealing furnace annealing tube and the surface scaling of the water inlet guide wheel encountered in the production of copper enameled wire, both are related to the accumulation of calcium and magnesium ions in hard water.

3. Influence on lubricating fluid.

Because the impurities in the water, especially the hardness components, will chemically react with the alkaline lubricating oil, which will consume a large amount of the alkaline lubricating oil, reduce its activity, reduce its effect, and accelerate the deterioration. Many manufacturers use pure water in the production of lubricating fluids, and the effect is very good.

The water quality of the washing liquid and cooling water (directly contacting the product) involved in the product should be strictly controlled, and the diameter of the filament should be higher. Mainly controlled by the following levels:

(1) Copper enameled wire and copper wire annealing water sealing water: meet the specifications of primary distilled water, conductivity is 10/CM, no CL, no hardness.
