20 since the early 70 century, twice the oil crisis to the world to energy-saving knock the alarm (in 1973 and 1979), and acid rain, ozone hole and the greenhouse effect and other environmental hazards to human beings to protect the environment a better understanding of the urgency and the importance of energy conservation, protect the environment has become the economic development of countries in the world much attention to the two main themes. States have committed to the development of energy-saving products, while strict environmental regulations. The world's paint industry conform to the requirements of the times, the provincial resources, energy, clean development goals, major paint companies even pay a high price, competing for the development of energy-saving, low pollution-based coatings, in order to maintain, consolidate and develop their own coatings market in the future in a strong competitive position. Powder Coatings is the energy-saving, low pollution-based paint is extremely important in a class.
Kriesheine Germany in 1952 the company's Erwin
Gemmer invented the fluidized bed coating method, the beginning of the development of thermoplastic powder coatings. Sames France in 1962 the company developed the electrostatic powder coating equipment, in 1964 the successful development of thermoset powder coatings. Enter the 80's, industrial waste gas, wastewater, waste residue on the environment causing serious pollution, Europe and the United States of volatile organic compounds (VOC) restrictions and regulations continue to publish, such as the United States clean air act (Clean
AirAct), Germany's clean air requirements (TALutf
Regulation), the United Kingdom Environmental Protection Act (Envi-ronmentalProtection
Act) and so on. Especially the 1992 United Nations Conference on Environment and Development, the Environmental Protection has become an important problem worldwide. Because of powder coatings with a solvent-free, pollution-free, a thick coating coating, spray coating recoverable overflow re-use features such as being focused, the corresponding rate of development is also accelerating.
1. Powder Coatings Status
China's rapid development of powder coatings industry in 2002 and an annual output reaching 270,000 tons in 2003 and an annual output reaching 340,000 tons, with an average annual growth rate of around 30%, far higher than the world powder coating industry 7 ~ 8% of the average growth rate. At present, production has leapt to the world, and become the world's leading powder coatings country. China's Powder Coating a single species, many low-grade, high-grade small; market confusion, it is difficult to control; technical inputs to small, specialized type of powder coatings with foreign big gap; lack of national standards and industry standards; energy consumption, and raw material consumption, and cost-effective poor; the low level of corporate governance and operating mechanisms has been beset by unreasonable and so was the development of powder coatings.
Powder coating industry in China after decades of development, has become the world's largest producer of powder coatings, the technology level and product quality are continuously improved. At present powder coating production enterprises is nearly 2000, but the technological level of enterprises and different levels of quality management, product quality is also good and the bad.
2. The future direction of powder coatings
Powder coating over the next few years will be the "four modernizations" direction of development: low-temperature curing, so that powder coatings can be adapted to heat-sensitive coating materials, and better align with the solvent-borne coatings; film, and can be used for a thickness of 30 microns for coating, in order to occupy more of the solvent-borne coatings market; function, including heavy-duty type, heat type, weather type, flame retardant, conductive type of material to be coated to provide special protection and decorative functions of powder coatings; specialization, automobiles, pre-coated steel and other special powder coating; art type, the development of matte, high light, high DOI, and metal flashing, as well as covering coarse powder coating substrate patterns. Several major industry-specific hot spots of powder coatings market:
2.1 shipbuilding industry, pipeline industry is a powder coating applications
China's steel tube on each of 100 million tons required. Steel tube construction in the national economy occupies a very important position, at present, has been part of the ship pipes spraying powder coating applications, the development momentum is fierce, with the powder coating technology continues to improve, and its development has broad prospects.
Pipeline Corrosion Protection of Epoxy Powder Coatings are a completely non-solvent to spray powder form and melting film-forming a new type of paint. There are questions of impact resistance and moisture absorption to be improved and enhanced, the researchers concentrate on a variety of powder coatings based on the modified material. Domestic product pipeline antisepsis epoxy powder coating and coating storage stability in terms of construction, compared with foreign products are still a certain gap. Epoxy Powder Coatings are new pipeline anticorrosion engineering of choice varieties of anti-corrosion coatings.
2.2 Powder Coatings future demand in the automotive industry's largest
The automobile industry a pillar industry in China are expected in 2005 China's car ownership society will reach 20.6 million. Vehicle has epoxy polyester powder coating of mixed type, polyester type, PVC and acrylic acid ester type. Powder coatings used in the automotive -1990 began in the early part of auto parts on the end of spraying powder coatings to be successful, as the technology becomes more perfect and improve the performance of powder coatings, is now fully able to meet the requirements of car paint, such as the appearance of decorative, Weather resistance, chemical resistance, anti-scratch and UV linear.
Current domestic powder coatings in automobile industry for many automotive engine, chassis, wheels, filters, joystick, mirrors, wiper and horn parts, such as painting. Because of technical limitations, the present powder coatings for automobile only monochrome series, such as in Tu and varnishes, powder coating because it is not as liquid as paint can quickly change color. Powder Coatings future vehicle development, will further enhance Weather resistance, UV linear, low temperature, the film and enhance decorative efforts. With the increasingly strict requirements of environmental protection and powder coating technology continues to improve, the application of powder coatings will become more and more widely.
2.3 Thermistor Materials Powder Coating is also an important application of the direction of
Paper, plastic, wood and furniture manufacturing has become one of the biggest users of coatings, and powder coatings have been successfully used in thermal coating materials, and really realize the industrialization of production, powder coating as a promising emerging Variety of coatings will be further diverted liquid coatings market. UV-curable powder coatings and low temperature curing powder coating manufacturing process to perfect the powder coating applied to thermal material possible.
2.4 Powder Coatings in construction applications and outdoor facilities also have broad prospects
Aluminum, aluminum alloy ceiling, security doors, aluminum alloy curtain wall panels, highway guardrail such as powder coating, according to statistics in 2003 the world's total production of thermosetting powder coatings 830,000 tons, of which powder coating weatherability for 281,000 tons, the total 1 / 3 strong. According to the experts predict that the next few years China's aluminum alloy profile will become the mainstream market. 2005 China outdoor Pure Polyester Powder Coatings significant increase in the full description of the market development potential. However, with the substantial use of outdoor powder, powder coating products on the customer complaints increased, mainly concentrated in the Weather resistance, alkali and water resistance, etc., required milling enterprises aroused great attention.
2.5 Private type, function-based powder materials will be occupied market
This is my powder coating from the latest annual meeting that the concept of powder coating raw materials. Czech Tatsu by Lu'an City Chemical Co., Ltd., Anhui Excalibur New Materials Co., Ltd, Fenghua South Sea Chemical Group,
DSM, Cytec., Tory, BYK and other companies to do the lecture topic. Although the powder coating raw materials, not cheap, but it is a sign of high-grade powder coating.
3. Powder Coatings Market Forecast
"Low profit" has become a powder will be many years涂料与涂装spokesman described as proper nouns, the Chinese Chemical Society of Professional Committee COATING Liu Secretary-General said: "The 2005 epoxy resin, polyester resin and other raw materials continued to Home high, powder coatings market growth rate also remained unchanged at 25%, so companies continue to increase their market share at the same time, profits have occurred in landslides, the risk of increased funding. Data statistics show that 2004 profit margins powder coatings industry as a whole a decrease of 35% ~ 40%. large enterprises through the effective operation of capital and to expand the operation scale in order to guarantee a certain profit level. "
It is understood that domestic now has around 2000 or so of powder coatings manufacturers. Du Pont Huajia major vendor to implement the many all-round development of the strategic base. DuPont, Akzo. Nobel, PPG and other famous powder coatings manufacturers in China set up a production base, which Akesu? Nobel companies in China has set up 10 powder manufacturing plant, is China's largest powder coatings manufacturer, accounting for China powder coatings market share of 15%. Francis USA Inc., Rohm and Haas also started in China powder coatings business or set up factories. With the joint participation of foreign capital, has shown that China's Powder Coating industry broad prospects for development.
It appears that regardless of the next powder coating companies are engaged in the management of raw materials or business must take into account the cost factors
