What is the future of metal surface treatment technology?

According to statistics, domestic products suitable for metal chemical surface treatment include fasteners for electricity, transportation and machinery, plumbing pipe fittings, nails, cement nails, ring chains, etc. (about 2 million tons per year). At present, the actual application of mechanical plating is only about 10,000 tons per year, and it is mainly processed and exported. With the development of the market, the requirements for metal surface treatment are getting higher and higher, and the metal chemical surface treatment process will replace the traditional electroplating and hot-dip galvanizing process in a considerable number of categories of workpiece surface treatment, and the hardware products of industrially developed countries have gradually developed to high-end products, and have transferred low-end hardware products to developing countries to set up factories for production.

Compared with India, South Korea, Vietnam and other countries, China has a greater market potential, including domestic and processing export markets, and is gradually developing into a major hardware processing and export country in the world. In recent years, with the development of metal chemical surface treatment technology in China, the amount of foreign commissioned domestic processing has increased year by year, distributed in Sichuan, Zhejiang, Henan, Hebei and coastal provinces. It can be seen that the metal chemical surface treatment process has a huge development space in China, coupled with the high cost of foreign mechanical galvanizing equipment and raw materials (420,000 US dollars for the whole set of equipment), and the complex process, which has created good development opportunities for the domestic mechanical galvanizing process and equipment.

With the enhancement of people's awareness of environmental protection, as well as the implementation of environmental protection regulations, the development of traditional galvanizing technology will be limited, mechanical galvanizing technology belongs to the "green" surface treatment technology, because of good social and economic benefits, mechanical galvanizing process has excellent application prospects.

The job prospects are very good, but the job is very dangerous, not very good for the body, and the working hours are very long.

It is very good, because the number of metal-related products is relatively large, so the requirements for technical personnel are also relatively high.

This job is very good because the job pays well, the hours are short, and there is a lot of leisure time in this pay.

Metal is very widely used in our actual life, and you can see all kinds of metals everywhere, such as the rice spoon we use for eating, as well as the aluminum alloy used for façade decoration in the home, etc., at this time, people will be confused about what the metal surface treatment worker mainly does? What are its employment prospects? In fact, it is for these metal surfaces to be polished to ensure safetyEmployment is also very good, now there is a lot of metal market, especially for decoration, the demand for materials is very large, let's analyze it specifically.

First of all, we have to understand that the work of metal surface treatment is to polish the metal, after all, it is an item with relatively high hardness, and safety is very important when it is usually used, so it is necessary to polish the metal to ensure that there is no protruding place, and it is still safe to use it at home, and the employment prospects of this industry are also very good, after all, the demand is large, think about the whole market There are a lot of decoration facades, and house decoration will also need to be used. So these raw materials are all metals, the most common is aluminum alloy, the market demand is great, employment is possible.

But this job has a certain impact on the body, after all, metal is a chemical substance, and the accumulation of long-term work for many years will produce a certain amount of *** for our body, so you have to think clearly about what you are doing, of course, the prospect of this job is also good, the salary is over 10,000 is OK, that is, it is more hard, but it is okay to be tired with a high salary.

Count the dust <>

It's just that I hope everyone can respect the profession of potato leakage, don't think that they are dealing with metal for a day, and the environment is better, you can disrespect it, think about Luo Yonghao.

In other words, we were born to change the world, which is nothing more than two possibilities, one to make the world a little better, and the other to make the world a little worse, which is the meaning of everyone's existence. As long as you don't steal or rob, hard work is to achieve your own meaning.

The main job should be to deal with some substances on the surface of the metal. Of course, it will also deal with some things like Tie Nian Qi Rust, and the employment prospects are still very good.

This job is mainly for the corresponding treatment and maintenance of some metal surfaces, the employment prospects of this profession are very good, and the salary is particularly good, but there are very high requirements for the professionalism of employees. Demolition Brigade.

It is mainly through chemical reactions that the metal reacts with the phosphating solution, thus forming a phosphate film that is insoluble in water on the surface. The prospect can also be rough, but it is more limited, it is recommended to leak more and learn a technology of reignation, and the skills are not pressing.

There are generally several types of metal surface treatment processes: electrochemical methods, including electroplating and oxidation. Chemical methods, including chemical conversion coating treatment, electroless plating.

Thermal processing methods, including hot-dip plating, thermal spraying, hot stamping, chemical heat treatment, and surfacing welding. Vacuum, including physical vapor deposition (PVD), ion implantation, chemical vapor deposition (CVD).

1. Electroplating is the process of using the principle of electrolysis to coat a thin layer of other metals or alloys on some metal surfaces, and it is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, so as to prevent metal oxidation (such as rust), improve wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics.

2. Chemical conversion film, also known as metal conversion film. It is the interaction between the surface atoms of the metal (including the coated metal) and the anions in the medium to form a well-adhesive isolation layer on the metal surface, and this compound isolation layer is called a chemical conversion film. The formation of the conversion film can be either a pure chemical reaction between the metal and the medium, or an electrochemical reaction.

3. Hot-dip plating is referred to as hot-dipting. Hot plating is a process method in which the plated part is immersed in a molten metal liquid to form a metal coating on its surface.

There are many types of metal surface treatment, which can be divided into three categories: solvent cleaning, mechanical treatment and chemical treatment according to their different characteristics, and can be subdivided into: electroplating, electrophoresis, anodizing, passivation, phosphating, polishing and etching. Common metal treatments are as follows:

Stainless steel: electroplating, polishing, wire drawing, electrophoresis, PVD, etching, color passivation;

Aluminum alloys: anodizing, electroplating, etching;

Magnesium alloy: electroplating, passivation film;

Titanium alloy: electroplating, anodizing;

Zinc alloy: electroplating, passivation;

Cast aluminum: electroplating, anodizing;

Iron and steel: passivation, phosphating.
