Take first see everyday construction, transportation, airports, warehouses and so on, we can say these industries are related to the use of color-coated many areas, color-coated material to be of good use in all sectors, it is very impressive, then the following color-coated here today we take a look at. Our own design, production scale manufacture of color coating production line can be divided into the following categories: speed of 120m / min of annual output 150,000 t, speed 80nYmin annual production 100,000 t, speed of 60m / min annual production 75,000 t, color steel roll manufacturer, speed of 40m / min of the annual 50,000 million t. According to curing methods can be divided into two categories: direct-fired heating and air-cured indirect heat cured. Direct-fired heat curing oven systems computing model is: On each set a curing oven gas burner, combustion exhaust gas circulation increase direct incorporation into the furnace circulating air oven temperature to ensure the normal required paragraphs. Two share a curing oven incinerator. The paint is diluted exhaust gas extracted after curing oven through the incinerator to be burned. Incinerator flue gas preheater disposed one, 250 ~ 310 ℃ cured paint diluted exhaust gas extracted after the furnace preheated to above 400 ℃, facilitates complete combustion of the exhaust gas in the incinerator. Known as the iron and steel industry, it said food plays an important role in national economy. After years of development, the Chinese steel big country already is, but the big but not strong. Since 1996, China's steel production has caitu 10 consecutive years ranked first in the world. At the same time, Chinese steel production is still emphasis on high energy consumption, low value-added products, some of the high value-added steel is still dependent on imports. 2008 China's total exports of 59.23 million tons of steel, total exports amounted to $ 63.4 billion; total steel imports 15.43 million tons, total imports amounted to 23.4 billion US dollars, the average price of steel imports than exports of steel higher than 40%. Substrate using difference galvanized sheet and galvanized sheet: zinc and aluminum zinc alloy layer compared to relatively active chemical properties, corrosion resistance and therefore a greater difference. Outdoor test under the same conditions showed Nantong color steel, galvanized plate galvanized sheet useful life of more than four times. (2) The surface paint material differences in surface paint resins include polyester resin (PE), polyester resin reinforced silicide (SMP) and polyvinylidene fluoride resin (PVDF). Conventional solvent coating system - polyester resin (PE): polyester resin paint (Regalar Polyester, abbreviated PE) is a conventional topcoat systems, such resin is not fat oleic impact on the comparative performance characteristics superior. Coating with good flexibility, adhesion and workability. But PE coating for resistance to sunlight and coating powder resistance is not ideal, so you need to use PE coating subject to several restrictions, are generally used for air pollution is not serious, in industrial environments or polluted areas, its life relatively lower. General life of eight to ten years. Currently on the market use more color-coated, including Bao board, Wu steel and most of Taiwan, South Korea imported plate, belonged PE coating. C. Pressure Processing: pressure processing proceeds painted steel substrate and coating it must be carefully chosen type; in addition the processing to be careful, especially the surface of the mold should be smooth, color-coated steel coil prices, in some cases also color steel coated with a protective film affixed to a protective coating; two, paint thinner 1. divided into two, two diluent and slow drying agent (more common), where sales volume Color, slow drying agent is not suitable for fast heating, otherwise there will be needle-like craters. 2. Shape: ○ (under the microscope) needle-like 3. Solution: Understanding is thinner characteristics, plus a reasonable use. Third, the board temperature setting plate unreasonable 1. fine coating curing temperature of the first stage play a decisive role, about the first stage 170 ℃. 2. Shape: ditto 3. Solution: The board set a reasonable temperature. Fourth, higher viscosity 1 viscosity, leveling of paint is poor. 2. :( dot shape) but not broken or cracked pinholes shape. 3. Solution: reduce the viscosity, reduce the film thickness. Five, the paint containing water, oil immiscible liquids. 1. These debris by roller coating applied to the surface of the plate, after curing baking evaporate. 2. Shape: Irregular 3. Solution: put an end to water, oil, paint is not easy to enter in the matter.
