no 9 galvanized wire

There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.

The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.

According to the different requirements of the industry, in the smelting furnace in accordance with the standard deployment, put the alloy ingot different weight, such as weave, Ming, paper, Lang, silicon, etc., the data out of the smelting is called gold ore. There are gray iron, white iron and the above-mentioned combined gold ore channels, each of which has its own distinctive characteristics, so they are used in industrial exploration and selection according to their own distinctive characteristics.
