Most customers will ask our sales staff. What is the output of your etching machine? How many products can you make 24 hours a day? I want to etch it deeply. All these problems are in the process. Ask the efficiency of the etching machine, then where do these efficiency yields come from? The etching machine, and then the most important thing is the dispensing of the medicine, the machine is just a tool, many customers etch slowly, but they don’t know the problem of the medicine.

 

1. Let me give you an example. Some of the substances produced by corroding stainless steel products affect the etching speed and effect. We must find this problem and solve this problem:

 

Especially 304 stainless steel etching, because the hardness of 304 stainless steel is too high, the mass concentration of FeCl3 (ferric chloride) not only affects the etching speed, but also affects the etching quality. When the Bamei of FeCl3 is less than 40Bé, the etching speed is slow, very It is difficult to reach the etching depth, and it feels like it is not etched by hand.

 

When the Baume degree of FeCl3 is around 60-70, the etching rate increases with the increase of FeCl3 mass concentration.

 

2, and then we will say that the concentration of hydrochloric acid, the etching rate of stainless steel increases with the acidity of the solution, so adding a certain amount of hydrochloric acid, phosphoric acid, etc. to the etching solution is beneficial to increase the etching speed, and can avoid the hydrolysis of Fe3+. Experimental results show The use of 8 ~ 10mL / L of hydrochloric acid is better. Of course, it depends on the etching machine. The etching made of PVC is not resistant to high temperature. If the hydrochloric acid is too much, the internal result of the machine will be easily cracked when it is hot, then the PP board etching machine The flexibility is not afraid of high temperature, and the temperature is high and the viscosity is higher.

 

3. Then the etching temperature is also related to the machine. The etching temperature not only affects the etching speed, but also affects the gloss, flatness and stability of the etched surface. From the viewpoint of kinetics, the etching speed increases with temperature. Increase, but the temperature is too high, the roughness of the etched surface is increased and the undercut phenomenon is obvious. Considering the etching speed, the etching effect and the thermal stability of the pattern film, it is preferable to control the etching temperature in the range of 40 to 50 ° C. The material of the machine must be resistant to high temperatures and can withstand high temperatures. So please choose Foshan Xin Hengli etching machine. Stable and durable.
