Do you really know about etching machines?

With the development of the economy and the progress of society, the use of etching machines has gradually entered various industries. It is a simple and practical small machinery with advanced etching machine technology, high production efficiency, more consistent and uniform etching rate, and other advantages. I believe that everyone's understanding of etching machines is not comprehensive during use. Today, the editor will briefly introduce the classification of etching machines and the influencing factors of alkali degreasing.

1、 Classification

1. Chemical etching machine

(1) The automatic chemical etching machines seen in the market today use high-pressure spraying and linear motion of the etched plate to form a continuous and uninterrupted feeding state to corrode the workpiece and improve production efficiency;

(2) The effective area and etching uniformity of the sprayed and etched metal plate have been increased, which is superior to splash etching in terms of etching effect, speed, and improvement of the operator's environment and convenience;

(3) After repeated experiments with a jet pressure of 1-2Kg/cm2, the residual etching stains on the etched workpiece can be effectively removed, greatly improving the etching speed compared to traditional etching methods. Due to the recyclable liquid of the etching machine, this can greatly reduce the etching cost and meet the requirements of environmentally friendly processing.

2. Electrolytic etching machine

Electroetching is the process of etching metals by utilizing the principle of anodic dissolution of metals in a liquid mainly composed of tap water or saltwater (under the action of electrolysis), and then turning on the etching power supply to achieve the purpose of etching. Electrolytic etching machines are all manual spray type and use saltwater as the etching solution. There are two types of power available

2、 Factors affecting alkaline degreasing

When using alkaline degreasing for workpieces with different types of metal materials and surface conditions, the etching machine should have different oil formulations for different metal machine parameters;

2. In addition to the content of various components in oil;

3. The working temperature for oil removal is generally not too high. On the premise of ensuring the quality of oil removal and working temperature, the larger the better. It is possible to add a small amount of high-performance surfactants, enhance wetting, penetration, and emulsification processes, lower the temperature, but still ensure effectiveness and oil quality;

4. In addition to measures to strengthen oil;

5. The removal time of etching machine oil depends on various working conditions. First, go straight to the alkaline solution, the better, especially when starting with alkaline solution, which has a better effect and requires a short time.

In summary, with the rapid development of technology in modern times, etching machines have become an indispensable product, which is more like a choice of the times. This article hopes that everyone will have a deeper understanding of the classification of etching machines and the influencing factors of alkali degreasing.
