The reason why galvanized iron wire is gray and speckled

The price of galvanized iron wire is relatively low, but the corrosion resistance is excellent. In the process of galvanizing iron wire production, it is often seen that the galvanized iron wire is gray and spotted. How is the cause of this problem caused?we are galvanized hard drawn wire and the best galvanized hard drawn wire,you can know it.
The reason why galvanized iron wire is gray and speckled
In the process of galvanizing iron wire production, first check the equipment to see if there is any problem, then look at the galvanizing process, whether there are factors that cause the product to change color, if none of the above problems exist, or on the same equipment This happens, and some are normal, then this time we have to consider the problem of raw materials. Some raw materials are unstable during production, and the wire itself has local defects such as burrs and small pits.

For this problem, you can use a magnifying glass to carefully observe the darkening of the surface of the galvanized iron wire, or look at the same batch of unfinished wire, generally only need to be careful to find the problem.
What should be paid attention to during the production process of hot-dip galvanized wire?
When hot-dip galvanizing wire is pickled, slowly put the wire into the cylinder to avoid acid splashing on the body. When adding acid, the acid must be poured into the water slowly, and the precautions for the operation of galvanizing iron wire should be prevented from being poured into the acid to prevent the acid splashing and injuring people. Wear protective goggles when working.
Hot-dip galvanized iron wire should be taken care of and safely. The coil should be placed gently and piled up reliably and neatly. It should not be higher than 5 disks.
In the process of galvanizing hot-dip galvanized iron, human skin is prohibited from direct contact with acid and alkali.

When the hot-dip galvanized iron wire acid mist exceeds the national target, it is necessary to adopt the method of management in time, otherwise it will be banned from production.
