    Under the new situation, although the construction coating market prospects are good, but the production enterprises in the production process is facing the most severe environmental protection and cost pressure. Relevant enterprises should raise awareness, promote the concept of environmental accounting costs, in the paint production, coloration link to introduce integrated equipment, to achieve cleaner production to create a sustainable development space.。 1. Analysis of the current situation
    1.1 Construction coatings market prospects are good
    According to the latest statistics of the China Coatings Industry Association, in January-August 2014, The total output of China's coatings industry was 10.5875 million tons, which is close to the total output for the whole of 2011. Among them, most of the sales growth comes from architectural coatings, experts expect that after a long period of time, the growth of the architectural coatings market will remain high-speed, the average growth rate of architectural coatings in 15% to 20%, while the average growth rate of industrial coatings is only 3% to 5%. Obviously, the growth of architectural coatings is optimistic, but to turn the potential into reality, architectural coatings need to increase product development and production in the new situation.1.2 The most stringent environmental protection law in history is about to be implemented
    the eighth session of the Standing Committee of the 12th National People's Congress on April 24, 2014 deliberated and adopted the revised Environmental Protection Law (hereinafter referred to as the Environmental Protection Law). This is the first major change to the Environmental Protection Act in 25 years, and the new Act will come into effect on January 1, 2015.For the first time, the new Environmental Protection Law has written the red line of ecological protection into law, increased penalties to solve the problem of "low illegal costs" for enterprises, further clarified the government's supervision and management responsibility for environmental protection, strengthened public supervision of the government and sewage units, strengthened the responsibility of enterprises for pollution prevention and control, increased legal sanctions against environmental violations, and made systematic provisions on the disclosure of environmental information and public participation by the government and enterprises., when we talk about the development of architectural coatings, we must first re-examine the survival of enterprises. Most paint enterprises in the production process, and do not pay much attention to clean production and energy conservation and emission reduction work, especially some small paint enterprises, in the production process in order to save production costs, with a lucky mentality, there is no clean production work. However, under the new situation, the environmental illegal costs of these enterprises will be greatly increased. Illegal costs include economic costs and legal liability costs, according to the "daily penalty" provisions, enterprises in the event of illegal discharge of pollutants, will face huge fines, and some of the illegal acts constitute a crime, but also need to bear criminal responsibility. As a result, many paint companies will be faced with the risk of being eliminated due to clean production and energy conservation and emission reduction.1.3 Coating raw materials and production costs continue to rise
    after the implementation of the new Environmental Protection Law, the paint industry will be subject to downstream industry brought about by product upgrading pressure and upstream industry brought about by the rising cost of raw materials pressure. At present, the domestic titanium dioxide industry leader has raised the price of titanium dioxide six times this year, while the titanium dioxide industry has environmental protection tightening long-term constraints.construction coating production costs include material costs, labor costs, management costs, and so on. At present, many enterprises still use the traditional manual coloring method for color paint production, its color process is like "face master and face" - more water, more water and more surface, after repeated attempts to adjust the color. This way it is difficult to control the balance between covering pigments and coloring pigments, resulting in higher material costs of coating products, and the speed of color adjustment is obviously not fast enough, the formula is not accurate, it is difficult to adapt to the needs of coating industrialization.the key factor in the traditional color palette is the colorist. Today, after 80, 90 young people gradually become the main force in all walks of life in society, and in the paint industry, the color adjustment work environment is dirty, the color adjustment process cumbersome, irregular working hours and so on led to the number of new young people. Coupled with the existing colorist's level difference is very large, excellent color palette shortage, so that colorist's salary rises. In east China, the monthly salary of experienced colorists has risen to more than 10,000.。 2. Coloring system and selection
    according to Chinese paint expert Dr. Shen Hao research found that China's paint has a history of 7000 years. For thousands of years, in order to meet people's needs, the color of the paint has been modulation. Early color palettes were done by adding pigments and visually using human experience, and it was not until the 1990s that computer coloring was introduced to China. After 20 years of development, the development of domestic color system has become increasingly mature, with a wide range of applications.concept of a 2.1 coating tonation system
    To some extent, coating production consists of two main processes, preparation and tointing of the base paint, as shown in Figure 2-1. The preparation process is the process of proportionally processing materials such as resins, pigments, additives and water into white substations, while coloring is the process of adding commercial slurry to the white substation to turn them into finished coating products. In the coating toning process, the use of the various components of the same is what we call the coloring system.
    2-1 paint production process diagram
    paint coloring system is generally composed of software, instruments, color cards, slurry, toned equipment, mixing equipment and related machinery. Color matching can be achieved in the production, circulation and sales of coatings, and therefore the color homoding system is divided into retail color system, store color system and factory color homeling system. But there is no strict limit to which link must be used in which color system, such as in the production of paint color, you can use the treasury color system can also use the factory color system, the final choice of which color system should be based on the enterprise's own situation and development requirements to determine. Paint coloring system using the packaging barrel color method, compared with the traditional large cylinder color palette, color system has almost no paint loss and paint residuals, there is no sewage discharge, and the cost of color adjustment has been greatly reduced.2.2 factory color
    mode of work in the paint production preparation process, we call it factory color. Factory color system according to the operating mode can be divided into the store and online two, the store room color adjustment refers to the pre-filled base paint packaging bucket injection of color paste for color adjustment, and online color palette is based on the color paint order, in order to on-line filling, toned way of production, Figure 2-2 for the factory online color map.Figure 2-2 factory online toning schematic
    factory online coloring system, according to the color of color paint, cover and film thickness and other parameters, coloring software automatically calculated varnish, white paint, color paste addition ratio, production management software according to color mixing formula, barrel count, paint net weight and other information to generate production orders, and finally by the industrial control device control filling, coloring, pressure cap, mixing and other mechanical equipment according to the preset program to complete the production. Treasury coloring is part of online color palette, and the differences and connections between the two can be found in Table 2-1.

    2.3 factory color system selection
    In recent years, factory coloring in the domestic development is very fast, better conditions of enterprises in the introduction of related equipment to solve the paint cleaning production problems. However, in terms of the current effect of use, the situation of enterprises is very different. Like a company in Nanjing, with 6 or 7 people color team, hundreds of barrels a day, has adhered to the barrel color adjustment for more than ten years, is recognized by the industry as a model of successful application of color system; In Zhongshan, Hangzhou, Tongxiang, Baoji, SixAn, Chongqing, Tianjin, Weihai, Qingdao, Luoyang and other places some factories are not optimistic, the introduction of color system is either not ideal, or can not work properly, or idle. The reason for this is that many companies introduce color technology systems without in-depth knowledge and complete evaluation. In layman's terms, most of them have been fooled.general, successful introduction of a tonation system requires several steps. First, figure out why you're buying a toned system. Enterprises are currently facing what problems, such as environmental issues, color problems, labor problems or management issues, etc. , to find out their own problems, to find a way to solve. Second, what kind of color system to buy. Need to do a good job of understanding and comparison, including the performance of the main equipment, coatings and color paste matching, color pulp cost-effective and so on. Finally, it is the evaluation of the scheme and supplier selection. Whether the final selection of the color system is appropriate is related to the normal use of the system, the key elements include the following: (1) paint product types and production capacity
    Due to the limitations of color measuring equipment, the current color throming system can completely solve the color application of flat coating products, but for paint coloring with irregular particles of objects is not applicable. According to the current tonment volume and development estimates to select the appropriate system, we recommend that the daily ton of color adjustment is less than 5 tons, and the color and batch of less enterprises choose the treasury color mode system, on the other hand, the need to choose the factory online color mode system.(2) color paste evaluation
    the color paste is the main consumables of the toning system, whether the choice is right is directly related to the long-term operation of the tonation system. The main evaluation factors of color palette for color system include:
    color space coverage - complete chromatography, coverage without blind spots
    weather resistance - protection of paint decoration performance
    stability - batch, volume coloring force stability, supply and logistics assurance
    environmental protection - environmental indicators requirements, ultra-low VOC, no APEO
    "Dry and wet - 24h dry knot test, to achieve more than 3 levels of
    compatible - through the machine and hand-stirring assessment
    price/performance ratio - key indicators, related to the cost of materials
    (3) supporting conditions
    coloring system applications supporting conditions including the enterprise's hardware environment and software environment. The hardware environment refers to the material conditions required for the operation of the toned system, including complete sets of equipment for coating production, the site where the tonation system is installed, and the fixed staff. Software environment is the need to establish a good color system to ensure the operation of the process and management system, including sound raw material testing and control, mature and stable production processes and related processes and systems. Another point is the support of enterprise management, the process of color adjustment system is different from the traditional color adjustment method, in the early stage of the operation of the system, it is possible that personnel training, assessment mechanism, production process and other aspects of management communication and coordination.(4) System Integrators
    Coloring System Integrators are suppliers that combine equipment, software, industrial control, and other components used in the color thromization process and provide training and services, rather than simply equipment vendors. Just like the well-known cars and computers, its products are integrated products, consumers do not need to know where a medium parts are produced, what performance, choice only need to choose the corresponding configuration according to the needs. The same is the color system, paint companies have a hard time figuring out how each device communicates and how to coordinate their work. If careless, bought a bunch of equipment to go home, to the workshop a swing, the result is to use the trouble, has become a good-looking decoration. Therefore, the choice of the right system integrators is very, very critical.。 3. The application effect of the online
    system
    3.1 production cleaning process includes two links: testing and production. When typing, the software calculation and correction of the formula are weighed with precision electronic scales, stirring with ink modulation knife, scraping card with wet film preparation, the process of using tools can be cleaned with coarse paper. During production, the base paint and slurry are injected directly into the barrel. The whole toning process does not flush the waste water, only produces a little solid waste, is really the realization of clean production.3.2 process automation
    online color technology system using advanced industrial control devices and monitoring software, the system components of the organic connection, so that the entire process of coating production by mechanical equipment to complete automatically. Automation of the production process reduces the amount of labor used and greatly reduces its labor intensity. 3.3 Management Information
    system is equipped with color technology software, management software and monitoring software, which relies on large databases for data sharing over the network. It can realize the management effect of formula, material, order statistical analysis and report generation, and also connect with the enterprise ERP, so as to realize the informationization of production management. 。 4. Conclusion
    China's traditional paint production methods are "three highs and one lows", that is, high pollution, high labor intensity, high uivity and low efficiency. Through the application of online coloring system, we can realize the production cleaning, process automation and management information, to achieve our hope of "three low one high", that is, low pollution, low labor intensity, low labor force uity and high efficiency of production.
