　　Where to sell painted rolls

　　The lightweight, beautiful, and excellent anti-corrosion properties of color coated rolls have sparked a trend of use in many industries, and they can also be directly processed. They are now widely used in industries such as construction, home appliances, furniture, and transportation.

　　Color coated roll coating structure: 2/1: Apply twice on the upper surface, once on the lower surface, and bake twice. The corrosion resistance and scratch resistance of single-layer back paint are poor, but it has good adhesion and is mainly used in sandwich panels; 2/1M: Apply twice on the upper and lower surfaces, and bake once. The corrosion resistance, scratch resistance, and processing formability of the back paint have good adhesion and are suitable for single-layer profiled panels and sandwich panels. 2/2: Apply twice on the upper and lower surfaces, and bake twice. The corrosion resistance, scratch resistance, and processing formability of double-layer back paint are mostly used for single-layer profiled panels, but its adhesion is poor and it is not suitable for sandwich panels.

　　Color coated coil substrate classification: Hot dip aluminum zinc substrate uses hot-dip aluminum zinc steel plate (55% Al Zn) as the new coating substrate, usually with an aluminum zinc content of 150g/㎡ (double-sided). The corrosion resistance of hot-dip aluminum zinc sheet is 2-5 times that of hot-dip galvanized sheet. Continuous or intermittent use at temperatures up to 490 ℃ will not result in severe oxidation or the formation of oxide scales. The ability to reflect heat and light is twice that of hot-dip galvanized steel plate, and a reflectivity greater than 0.75 is an energy-saving building material. The product of hot-dip galvanized steel plate coated with organic coating on hot-dip galvanized substrate is hot-dip galvanized color coated plate. Hot dip galvanized color coated sheet not only has the protective effect of zinc, but the organic coating on the surface also plays a role in insulation protection and rust prevention, with a longer service life than hot-dip galvanized sheet. The zinc content of hot-dip galvanized substrates is generally 180g/m2 (double-sided), and the zinc content of hot-dip galvanized substrates for external use in buildings is 275g/m2. Electroplated galvanized sheets are used as substrates, and the products obtained by coating with organic coatings and baking are electroplated galvanized color coated coils. Due to the thin zinc layer of electroplated galvanized sheets, the zinc content is usually 20/20g/m2, so this product is not suitable for outdoor use in making walls, roofs, etc. But due to its beautiful appearance and excellent processing performance, it can mainly be used for household appliances, audio systems, steel furniture, indoor decoration, etc.

　　Recently, the list of advanced collectives for the protection and statistics of the steel industry in 2014 was announced, and Shagang was listed. This is another honor for Shagang after being awarded titles such as "Protection Demonstration Unit", "Advanced Enterprise in Clean Production Protection in the Steel Industry", and "Four Star Energy Efficiency Enterprise". Shagang is the only four-star energy efficiency enterprise in the steel industry. Experts say that in fact, Europe and the United States did not launch a double anti on steel products this year. In addition, steel products now have a price advantage, mainly in terms of cost and scale effects, rather than subsidies. Therefore, this statement by the US is only one-sided, reflecting the fact that Europe and America only look at others' mistakes but do not find their own reasons. To this end, it is necessary to improve the mechanism for enterprise exit and do a good job in post production work, and deal with the problem of reemployment caused by the suspension and reduction of production by enterprises. Further improvement should be made to the basic conditions of coal mines, such as resource depletion, high mining costs, severe losses, and no hope of turning losses around; We can refer to the policies of the original state-owned coal mines and study the establishment of a coal mine exit mechanism to guide aging coal mines to exit steadily and achieve ineffective production capacity.
