After purchasing a CNC plasma cutting machine, many customers will find such a problem in the process of cutting with a cutting machine. When cutting a steel plate, after the cutting is completed, a thin layer will be found on the surface of the plate. Rust. This problem is very unfriendly to our products. If customers see these things, the desire to buy will surely be greatly reduced. Therefore, we must deal with this issue. However, many customers do not know how to solve it. Today, Xiao Bian gave you two common methods:
Aluminum Micro channel Tube is a kind of extruded tube with lots of holes.It has good performance in heat exchange area.It is normally used in producing aluminum condensor. The key technic to produce Aluminum Micro channel Tube is the tooling. Trumony has its own tooling team.Which enables Aluminum Micro channel Tube continues quality and fast delivery.There are also plain surface Aluminum Micro channel Tube and Aluminum Micro channel Tube with surface Znic spray. Znic Spray will be better corrosion resistance.We have a list of ready tooling which enables our clients to choose and reduce their invention cost. Looking forward to your cooperation.

Before explaining, we first do two small experiments to see the specific phenomenon:
Experiment 1: After high-temperature baking, the surface of the steel plate will become charred colors such as gray, black, brown, yellow, blue, iron red and other colors. This color does not look good and has no use value. The use of complex water can restore the original whiteness of the steel plate.
Experiment II: Using a plate printed with ink, after high-temperature grilling, so that the surface becomes dark brown and variegated, and then soaked in white water for more than 1 minute to make the black ash fade out of the sample. Parts of the lines covered by the ink are not whitened.
After the above two experiments, we can summarize the following two methods:
Method one: For high-temperature oxidized discolored steel plate can be washed off with steel whitening water, use of white water can restore the original white plate.
Method two: After pickling must be fully rinsed with water and wipe, to avoid secondary pollution, you can use manual polishing machine, a thin layer, it is easy to throw away.
Therefore, if we appear in the cutting process, the surface of the steel plate appears rust, then we do not have to panic, the majority of customers can follow Xiaobian method to remove him.
