Chrome Plating Production Line
Metal electroplating line is widely used in aircraft and auto parts, machinery parts, metal, hardware processing industries, including cooper plating, silver plating, zinc plating, nickel plating, gold plating, chrom plating, anodizing, electrophoresis production line,etc.
Chrome plating refers to the act of plating chromium as a plating layer on other metals. Chrome Plating Production Line,Chrome Plating Line,Chrome Electroplating Line,Hard Chrome Plating Line Wuxi Xingyi Intelligent Environment Protection Equipment Co.,Ltd. , https://www.xingyimachinery.com
During the “10th Five-Year Plan†period, China’s coal companies’ fixed assets investment will be about 300 billion yuan, which will form a production capacity of 800 million tons in the next few years. It is expected to be released in 2007 in a larger scale, resulting in a greater impact on the coal market. Big impact. In 2006, the country also cancelled the coal export tax rebate, lowered the coal import tax rate, and imposed a 5% tariff on coal exports. This will directly affect the coal import and export situation, and the domestic coal market competition will be fiercer.
In the new year, the cost pressure on coal companies is also increasing. Industry sources said that the introduction and implementation of a series of policies and measures by the state on the coal industry is conducive to the long-term development of the industry, but some policies have a significant impact on the cost of coal in the short term, such as the increase in land use fees and the use of coal resources. As well as the mine environmental governance and ecological restoration compensation mechanisms to be established, it will directly affect the economic benefits of coal companies.
Chromium is a kind of silver-white metal with a bluish tint. Metal chromium is easily passivated in the air, and a very thin passivation film is formed on the surface, thus showing the properties of precious metals.
The chromium-plated layer has a very high hardness, and its hardness can vary within a wide range of 400-1200HV according to the composition of the plating solution and process conditions. The chromium-plated layer has good heat resistance. When heated below 500℃, there is no obvious change in gloss and hardness. The temperature above 500℃ starts to oxidize and discolor, and the hardness starts to decrease when the temperature exceeds 700℃. The friction coefficient of the chrome layer is small, especially the dry friction coefficient, which is the lowest among all metals. Therefore, the chrome-plated layer has good wear resistance.
China's coal market competition will intensify this year
According to the analysis of related departments, due to the country’s strict control over the rapid growth of investment in fixed assets and the development of high-energy-consuming industries, the demand for China’s coal market will be reduced in 2007, thereby aggravating the competition in the coal industry.
