Color coated color coated paper, also known as organic coated sheets or pre-coated steel, which is a metal sheet (cold rolled plate, hot galvanized plate, aluminum plate, high aluminum plate, stainless steel, etc.) as the substrate, in various surface coating or organic coating or a laminated film from a plastic. Because it is a complete surface coating roll in metallurgical plants, for users directly processed into products, so also known as pre-coated sheet. Both advantages of both organic polymers and color-coated steel sheets, both excellent colored organic polymers, formability, corrosion resistance, decorative, but also high-strength steel sheet and ease of processing, can be easily carry out punching, bending, deep drawing, welding and other processing. This makes organic coated steel products made with excellent practicality, decorative, workability and durability. Now color-coated variety, about more than 600 kinds, but still does not have a uniform classification, because it is difficult to find a standard to distinguish between the many varieties, but also the manufacturers has its own unique equipment, technology, product range variety. Colored steel substrate was cold-rolled substrate, galvanized substrates and galvanized substrates. Coating types can be divided into polyester, silicon modified polyester, segregation fluoride and plastisol. Colored steel surface condition can be divided into coated plates, embossing plates and printing plates, painted steel appliances widely used in construction and transportation industries, the construction industry is mainly used for steel plants, airports, warehouses and freezing, roofs of industrial and commercial building walls and doors, buildings use less color plate. Plastic difference is that it is different constituent material. Magnet can suck move. Color six characteristics 1. Light weight: 10-14 kg / m, equivalent to a brick wall 1/30 2. Insulation: core material thermal conductivity: λ <= 0.041w / mk. 3. High intensity: for smallpox envelope bearing plate, bending compression; Fair Housing without pillars. 4. Bright color: without surface decoration, color galvanized steel coating retention in 10--15 years. 5. Install flexible and efficient: The construction period can be shortened by more than 40%. 6. Oxygen index: (OI) 32.0 (provincial fire product quality inspection stations). Color-coated powder board a comparative advantage, more environmentally friendly, economical; color-coated plate than dusting, painting board reduced paint environmental pollution, as people's living standards, people are increasingly strengthen environmental awareness , such as the economically developed Pearl River Delta region has been difficult to again build dusting been approved, and to put a dusting input costs are also high, and the use of color coating can reduce this part of the investment; second, more beautiful; Whether dusting board craft no matter how well it is inevitable to avoid the surface paint "orange peel" phenomenon, and the Year of old paint easily fade; and colored steel plate color pressure plate is color-coated steel, the roll cold-formed into a variety of wave pressure plate, which is suitable for industrial and civil buildings, warehouse, special construction, large span steel structure housing the roof, walls and interior and exterior decoration, etc., a lightweight, high strength, color-rich, convenient quick construction, earthquake, fire, rain, long life, maintenance-free characteristics of color pressure plate is color-coated steel, cold-formed by rolling into a variety of wave pressure plate, which is suitable for industrial and civil construction, warehouse, special construction, large span steel structure housing the roof, walls and interior and exterior decoration, etc., a lightweight, high strength, color-rich, convenient construction, earthquake, fire, rain, long life, maintenance-free characteristics , it has been widely used. Cold pressed or cold-rolled steel sheet molding steel. The use of organic coated steel sheet steel (or color steel), galvanized sheet steel, corrosion sheet steel (asbestos-containing asphalt layer) or other thin steel plate. Pressure plate unit having a light weight, high strength, good seismic performance, rapid construction, appearance, etc., are good materials and components, mainly for the building envelope, the floor can also be used for other structures. According to different functional requirements, pressure plate can be pressed into a wave, hyperbolic wave, ribbed, V-shaped, stiffening type. Roof and wall thickness of 0.4 to common 1.6 mm; when used in load-bearing floor or silo thickness of 2 to 3 mm or more. Wave height is generally 10 to 200 mm. When not stiffening, its high-thickness ratio should be controlled at less than 200. When using a long pass roof, its slope can be 2 to 5%, the deflection of not more than l / 300 (l to calculate span). Thin pressure plate because the original board, directly affects the quality of life of anti-corrosion coatings, in order to meet the requirements of the processing and rust, coated steel basis having the relevant provisions of the inspection. Under normal circumstances the steel sheet can also be used according to requirements, the pressure-type anti-rust paint and then painted or stainless steel sheet of the original board. Pressure plate roof for industrial plants, when the wall, no insulation requirements in the general case, each square meter of steel is about 5 to 11 kg. There is insulation requirements, the available mineral wool board, glass wool, foam, etc. for insulation. Pressure plate made of a combination of binding and concrete slabs, wood template can be omitted as a load-bearing structure. At the same time to strengthen the binding force of the pressure plate and concrete, should be pre-welded on steel studs or suppress bidirectional stiffeners. Application Development What is the most important performance painted steel market, most people think that a complete description of painted steel on two: First, the thickness of the second color, such as 0.5mm lime, etc., as if the other is not important. In fact, the complete expression of a painted product from five major aspects should be described: the mechanical properties of the substrate (yield strength, tensile strength, elongation), coating properties (coating type, coating adhesion, coating weight), coating properties (thickness, T bending, impact, hardness pencil, chalk resistance, salt spray resistance, durability, etc.), surface quality (defects, gloss, color, coating fineness), other properties (plate type, size precision, tolerances, etc.). Different groups of people (architects, owners, processors, etc.) to this understanding is not the same. From the production and use of painted steel angle of view, the most important performance of painted steel is its durability!

Color coated steel is cold rolled steel and galvanized steel substrates, after surface preparation (degreasing, cleaning, chemical conversion treatment), coated with a continuous coating method (roll coating method), after baking and cooling system into the product. Common 2-coat two baking type continuous color coating unit processes the main production processes are: → coiling galvanizing process after uncoiling → pretreatment → coating → baking → Process 137 4.88 87% 1.56 95% 8.75 34.6 1.9 78 6.3% 15 222 1.84 58% 91% 95% 14.6 0.8 5 1.9 5 1.93 61% 83% 5. Symptom: a unit with DE as an additive, when the groove galvanized bright as a mirror, but in the placement process, the zinc layer peeling off one after another. Analysis: This is caused because the coating brittle. Zinc coating flaking off into pieces with your fingers grind very easily into powder. The reason is because the one-sided requirement bright coating, blind brightener added so much of vanillin. Treatment: scrap metal plate hanging in large current handling, human consumption, directly caused by normal color. Another method is to add granular activated carbon to adsorb excess brightener vanillin out, and then the precipitate filtered. Production in general use before the law. Production of additives should be less plus, spare normal zinc coating was yellow rice can be. 6. Symptom: zincate will occur blistering. Analysis: There are many reasons blistering, which are described as follows: ① the nature of the bath itself: Electrolyte own lack of activation of the steel surface is poor. ② quality and quantity of additives: good quality DE, should be yellow, if delamination, color such as red-brown or brown, if not sparkling, there will be this or that fault is added to the bath. Additives are added too much, too much coating inclusions, increased stress, and foaming and brittle. In winter, in the absence of heating, the most prone to blistering. Because the bath temperature is low, the additive adsorbed on the surface of the part and more (low temperature, is conducive to the adsorption of additives), coating mixed with more, more sparkling. Additionally, vanillin added more glittering coating is enough, brittleness, blistering caused by the brittleness. ③ before plating (including into the slot in front of a weak acid corrosion) is bad. ④ bath of purification: metal impurity ion content is too high will cause coating blistering. ⑤ properly controlled operating conditions: If the current is too large, the temperature is very low, all will cause organic inclusions, cause blistering. ⑥ linked with cause blistering. ⑦ thick coating around the edges, and blistering caused by too much stress. Treatment: good technical management, strict compliance with the operating process, the bath should regularly analyze, regular feeding, additive add less spare, regular filter, the filter should be once every quarter. ① added 3 ~ 5g / L of NaCN, in order to increase the activation of iron and steel parts, while at the same masking effect of heavy metal impurities in the bath. 3 ~ 5g / L of NaCN in line with conditions of discharge. ② Additives qualified, in the course should be continuously dropped, in order to keep its content constant. ③ scrupulously to do pre-plating processing, steel parts galvanized plating should complete pre-treatment process: the four main processes chemical degreasing, acid descaling, electrolytic degreasing before plating activation. Each step should be careful operation, strict cleaning. Prior to plating a pickle activation step is indispensable, and then washed with water to plating. Activation is to make the steel surface passivation layer removed. ④ Once the additive, brightener adding too much, or heavy metal impurities, or bath decomposition products more, you should perform a large handle. ⑤ winter should control the liquid temperature, the temperature should be above 15 ℃, the absence of a heating device, the additive should be minimal. ⑥ hanging unavailable soldering process if solder should dip. Plastic film wrapping it is not good. ⑦ strict control of coating thickness, the edge is not more than 20μM, otherwise foaming edge. 7. Symptom: throwing ability was poor. Analysis: If Zn2 + high concentration, low NaOH concentration will affect the throwing ability. In addition, poor quality or low amount of additives can also affect the throwing power. Processing Method: Adjustment NaOH: ZnO = 10 ~ 12: 1, for some blind hole deeper parts, the requirements of the higher covering power, can be added to "MB" Antioxidant (2-mercaptobenzimidazole), added in an amount generally is 0.1 ~ 0.2g / L. Effect should be added at the beginning is not obvious, it will take effect after a week. 8. Symptom: the coating has more stripes and airflow. Analysis: The main cause of this type of failure is alkaline zincate current efficiency is too low, caused by hydrogen evolution. If the cathode current density is increased, the current efficiency will continue to decrease. A large number of hydrogen evolution, resulting in the coating to produce gas stream, stripes, this phenomenon in the winter when the liquid temperature is low and more obvious. Treatment: cathodic current density is not too large, liquid temperature control in more than 15 ℃, DK controlled 1.5 A / dm2, if there is no heating device, DK should be controlled at 0.8 A / dm2. If the phenomenon is more obvious, some of the surface active agent may be added, which will help to precipitate hydrogen. 9. Symptom: big rack plating current to open a small, deep-plating ability, deep recesses uncoated. Current open big, singeing rack ends. Analysis: zincate their throwing power is better. But for complex parts, it's sunken deeper level, the current open a small, often thin coating, passivation after being etched, it must be with a large current. Treatment: accurate bath ingredients and additives, brightener proper dosage, possible to open a large current, the deep recesses of parts have a certain thickness of the coating. To avoid singeing frame ends, you can set an auxiliary anode rack ends, so part of the current installation of color-coated surfaces will not allow metal filings, cuttings flow to the auxiliary anode, chips and other metal objects such as rivets and fasteners and other residues, because metal residues after erosion caused by rust. These residues, once discovered, requiring immediate sweep from the roof, or at least at the end of each day of construction for cleaning. Avoid walking on it to avoid damage to the film. In the strict requirements of the occasion, the building installation shall be assessed within 2 weeks, in order to remove residual material may be rusty. At this remove residue will help maintain long-term appearance of the roof. Non-ferrous metal smelters (copper, zinc, aluminum, lead) is the most challenging service life of painted steel. But a reasonable selection of materials, design, and environmental investment, etc. to ensure or improve the life of pre-painted steel sheet. 10-year replacement or maintenance should be able to do (Lanzhoulvye 2001 using fluorocarbon Baosteel steel). Steel mill (Baosteel 1420 Cold Rolling Plant, 1997 construction), power plants also produce corrosive media, but the experience has long-term use of painted steel (Shanghai Waigaoqiao Power Plant in 1993 use). Machinery manufacturing (automotive, turbine, machine tools, etc.) do not substantially negative impact on pre-painted corrosion, but pay attention to these industries may have heat treatment furnaces, boilers, etc. will also affect the local environment, handled properly will bring color coated steel corrosion, especially in the processing of the lesion or trimming. Warehousing and logistics industry developed rapidly, the use of light steel is also up, color coating itself does not cause corrosion, painted steel choose it mainly consider the impact of the environment, in general such a project are concentrated in the industrial development and heavy traffic , which is an industrial environment and coastal areas. Color-coated paint because it is a roll up, the paint surface is very smooth surface is substantially no "orange peel" phenomenon, it proved caitu spend years abroad not fade, surface gloss according to; three, saving factory space, saving human resources; build a dusting bound to take up a large amount of factory space, need to ask a lot of workers to production, while the land and human resources are so strained in the Pearl River Delta in terms of color coated can be thought boss Deals and how much trouble; Fourth, reduce the turnover of raw materials, improve production efficiency; stamping operation after dusting need to spray painting workshop production assembly and not directly in the production output of the season not to mention the often coated steel sheet has a light and beautiful and good corrosion resistance, can be directly processed, it gives the construction, shipbuilding, vehicle manufacturing, the furniture industry, electrical industry to provide a new raw material, played a steel and wood, efficient construction, energy conservation, prevent pollution and other good results. Use galvanized steel color coated steel substrate, in addition to zinc protection, organic coatings from zinc layer covering the isolation to prevent rusting steel, longer service life than galvanized steel, it was introduced coating service life than steel galvanized steel 50% longer. However, in different areas and use different parts of the same coating weight, the same kind of paint color coated plate, the same thickness of the coating, its life will be very different. For example, in industrial or coastal areas, due to air in the role of sulfur dioxide gas or salt by corrosion speed, service life is affected. During the rainy season, long coat soaked by rain or dew in the day and night temperature difference is too easy to site, will quickly corrode life will decrease. Color coated steel manufacturing buildings or factories, often by a long service life when rain washed, otherwise, due to sulfur dioxide gas, salt and dust by and affecting. Therefore, in the design, if the inclination of the roof of the larger, more difficult to accumulate dust and dirt, the longer life; for the area or part of those not rain washed down frequently, should be regularly rinsed with water. Outstanding outstanding use of color-coated using raw materials to be color-coated in various industries, which is very impressive, mainly seen in the construction Take usual, transportation, airports, warehouses and so on, we can say these industries are is the use of color-coated repeatedly about the scope, so today we are here to work together to know the following about. The primary use is divided into color-coated mall mall construction, household appliances and transportation and other three some, during the construction of the category accounted for the largest share, followed by household appliances industry, transportation accounts for only a somewhat less. Construction with color-coated galvanized steel sheet and is usually hot galvanized steel as the substrate, the first processed into corrugated board or after the polyurethane sandwich fit for creating steel plants, airports, warehouses, cold storage and other industrial and Commercial construction roof, walls, doors. Appliances color plates usually galvanized and cold as a substrate for the production of refrigerators and large air conditioning system, freezer, toaster, furniture and so on. The transportation is usually galvanized and cold plate for the substrate, mainly for the oil pan, car interior parts. Related to outstanding use of color-coated material, it is desirable for everyone to be more about presentation, can play to assist you know the effect of color-coated material so as to be useful to ensure the safety of the use of cold-rolled substrate type substrate color coated steel from the cold color plate rolling production base, with a smooth beautiful appearance, and has the processing performance of cold-rolled sheet; but any small scratches are the cold-rolled coated substrate surface is exposed to air, so that the exposed iron at quickly generate red rust. Therefore, these products can only be used for temporary quarantine measures and less demanding for interior timber. Galvanized color coated steel sheets coated organic coatings obtained on hot dip galvanized steel sheet is galvanized color coated products. Galvanized color coated with a protective effect in addition to zinc, the organic coating on the surface is also cut off from the protection against rust effect, longer life than hot dip galvanized sheet. The amount of zinc galvanized substrate is generally 180g / m2 (double-sided), the amount of building use galvanized hot dip galvanized substrate of up to 275g / m2. Hot galvanized color coated on request, can also be used as a pre-painted hot galvanized steel substrate (55% AI-Z n and 5% AI-Zn). Galvanized color coated galvanized sheet for the substrate of electricity, the resulting coated with organic coating baked products for galvanized color coated, galvanized sheet because the zinc thin, usually zinc content of 20 / 20g / m2, thus The product is not suitable for use in the outdoor production of walls, roofs and the like. But having a beautiful appearance and excellent processing performance, and therefore can be mainly used in home appliances, audio, steel furniture, interior decoration and so on.
