How to clean stainless steel cutting?

        In recent years, along with the rapid development trend of China's economic development, the consumption of stainless steel plate in China also shows a sustained growth trend. From 1990 to 2005, the average growth rate of the apparent consumption of stainless steel plate in China was 23.4%, which was four times of the current international growth rate (the average annual growth rate of the current international apparent consumption of stainless steel plate was 6%). The continuous growth of stainless steel plate consumption in China has stimulated the rapid development trend of China's stainless steel plate industry. With the help of relevant current policies of government departments, in less than ten years, China's stainless steel plate production has increased from 200000 tons in 1998 to 5 million tons in 2006, and its production capacity has also increased to more than 10 million tons.


        Common stainless steel cutting water tower metal surface treatment technology has the following types of solutions:

        1. The atomization phenomenon of white primary color on the surface is solved; 2. The surface mirror glass is bright; 3. Color the surface.

       

a. Solution to the atomization phenomenon of white primary color on the surface: in the production process of stainless steel plate, after steel coil, edge binding, electric welding or manual service, the problem of surface burning and heating is solved, resulting in gray black air oxide scale. The key of this kind of hard black gray air oxide scale is two eo4 components, nicr2o4 and NIF. Before, hydrochloric acid and sodium cyanide were generally used to carry out strong etching to remove it. But this kind of way costs a lot, environmental pollution, harm to the body, corrosion is very big, slowly eliminated. At present, there are two key ways to solve the problem of air oxide scale: sandblasting (shot) method: the key is to choose the way of spraying micro glass marbles to remove the gray black air oxide scale on the surface. Chemical method: a kind of environment-friendly pickling passivation paste and cleaning solution containing inorganic preservatives without harmful substances at room temperature are used for soaking. And then achieve the primary color of stainless steel plate white atomization phenomenon to solve the problem. Stainless steel plate laser cutting production processing is solved, most of them look like a dull color. This kind of method can be used for large, medium and complex commodities.


b. Bright solution of stainless steel water tower surface mirror glass: according to the complexity of metal products and customer requirements, grinding polishing, chemical polishing, electrochemical polishing and other methods can be selected to achieve the mirror glass gloss. The advantages and disadvantages of these three methods are as follows:


c. Surface coloring solution: stainless steel plate coloring not only gives stainless steel metal products a variety of colors, improve the color pattern of goods, but also improve the wear resistance and corrosion resistance of goods.


Compared with the development trend of stainless steel plate industry in China, the development trend of stainless steel plate production, processing, logistics and distribution service manufacturing industry in China is relatively backward. Especially in recent years, the level of basic necessities of life of households in China has been further improved, and the consumption of stainless steel plate has already entered the level of basic necessities of life of ordinary households. In 2006, the apparent consumption of stainless steel plate in China has risen to the level of 6 million tons, It has established a very good consumption base for the development trend of stainless steel plate deep processing industry in China. In addition, in order to comply with customers, stainless steel metal products companies will try their best to improve product quality and seize the market, which will show a very good development trend for surface production and processing of stainless steel plate, such as electroplating process, chemical polishing, shot blasting solution, etching process, coloring, coating production and processing.
