Coloring Technology Of PE Pipes

PE pipe is a type of pipe widely used in the current pipe market. In order to make the PE pipe more beautiful, the manufacturer has also conducted research on its coloring, so it is necessary to understand its coloring. The following will explain these knowledge in detail. Let's take a look together.
1. PE tube ion deposition oxide or oxidation method, which is more suitable for processing large quantities of products. For example, many of the watch cases and straps we usually wear are plated with titanium gold, and the color is usually cash yellow. The principle of this method is to make the stainless steel workpiece evaporate in vacuum in the vacuum deposition machine. Due to its high cost and high investment, it is not suitable for processing small batch products.
2. High temperature oxidation method is to keep the workpiece within a certain process range and then immerse it in a specific molten salt. After a certain chemical reaction, a certain thickness of oxide film will be formed, presenting various colors.
3. Chemical method is the process of forming the color of a thin film through chemical oxidation in a specific solution, but the color of the product can only be maintained consistently through the control of a reference telegram. 'Because of the law' is widely used.
After understanding the coloring techniques of PE pipes, we also added an additional option in the later selection process, which can be identified by color.
