The main reason the wire cup brush is black is the oxidation of the steel surface and air.
Wire cup brush, especially wire rollers, are usually used in steel or aluminum surface treatment plants. A series of stainless steel wire cupo brushes are installed on the fully automatic high speed brush polishing machine (brush polishing machine).
Cup wire brush, as one of the industrial brush series, its application field is very wide. The most widely used industrial cup wire brush are mechanical processing, shipyards, shipyards, pipe welding plants, steel plate rust removal and so on.
The cup wire brush is widely used. Mainly used in ship repair, shipyard welding welding slag, pipeline welding slag, machining deburring, machinery factory rust removal and other purposes.
The main reason why wire Cup Brush is black is caused by oxidation of steel surface and air. My advice is to soak the Wire Cup brush in hydrogen peroxide or 84 disinfectant for 10 minutes before using the wire. This will soak off the oxide layer, and then rinse it off, so it's ready to use.
In general, the larger the diameter of the round brush, the better the effect.
