gradient coating process for the Chinese high-speed rail by color -
high-speed rail train water-based coating market prospects broad
Shanghai November 18, 2019 / PRNewswire / – in recent years, the rapid development of Chinese high-speed rail technology has significantly changed the way people travel and lifestyle, the needs of different markets and lines of domestic and international high-speed rail train painting also put forward higher requirements. Zhang in Beijing high-speed rail trains intelligent design has been published in a special train named “Spring Snow number” of its unique design blue and white gradient bring a new visual experience crystal clear ice and snow, causing widespread concern. The prototype coating using coating raw materials Korth hit by three rivers and bright Kewei Ze Industrial Coatings Co., Ltd. in Changchun Railway Vehicles Co., Ltd. (CNR) to build cooperation.
Korth record in 2019 China International Coatings Show display upgrade type of high iron coating solution and sprayed color gradient effect
because of its rich color gradient changes, has been favored by the designer, it is widely used in various industrial design. However, due to high demand for coatings and coating processes, gradient rarely been used in the design of high-speed trains. The prototype formulations by using a unique color and spraying methods, to achieve a gradual color effect. Thanks paint raw materials from Korth Chong, the coating effect is more outstanding performance in color, coating weather resistance, better UV resistance, gloss more durable, to ensure the train remains beautiful appearance after a long run. In the 2019 China International Coatings Show in Shanghai New International Expo Center November 18 to 20, Korth Chong (Booth No: W2, B05) are showing the kind of car that subsection gradient coating effect of hot metal and the latest high coating solutions.
water-based coating market prospects
According to the national railway network plan, during 2021-2025, the national high-speed rail line grew from 30,000 km to 38,000 km, market demand for high-speed rail trains is still a huge space. Meanwhile, the Chinese high-speed rail with excellent performance and technological advantages, has become China’s infrastructureConstruction of “going out” of a “golden card”, higher market need to face different requirements of coating.
In addition, with the social environmental protection, sustainable development of cognitive gradually deepened, coating applications including rail transportation, including the rapid transition to being environmentally friendly water paint. Currently, high-speed train is still solvent-based coating. In addition to breakthrough innovations in high-speed rail gradient field of painting, Korth Chong has been committed to providing water-based coating solution for high-speed rail trains, respond to market demand. Currently, Korth Chong easy to spray waterborne polyurethane coating raw materials and series solutions have been successfully applied to the country more urban rail, subway and other projects, and began to paint with bright Kewei Ze rail transportation and other partners to innovate, to develop high-speed rail market.
Korth Chong developed an upgraded version of waterborne coating raw materials products and solutions that can better meet the long-distance high-speed rail, high-speed operation requirements. The aqueous upgraded high-speed coating solution has been applied to light Ke Weize aqueous coating system which has the following characteristics:
-
better weather resistance, chemical resistance and wear Resistance: as part of the high-speed upgraded aqueous coating solution, the protective varnish is the outermost coating of high speed trains. Compared with the traditional rail traffic paint, the upgrade has better weather resistance, chemical resistance and abrasion resistance, whether it is the way the sand zone, or cleaned every day, can ensure beautiful appearance of mind.
-
stronger adhesion and heat resistance, water resistance: high-speed rail shuttle train travel between the vast area, often encounter high temperatures, heavy rain. The upgrade program uses a two-component water-based paint basecoat, stronger adhesion than a single component product, and having better water resistance and moist heat resistance, even in hot and humid environments, but also to train the surface intact.
-
better chip resistance: high-speed trains during high-speed operation, splash pebbles striking vulnerable, it is necessary to face the coating surface of the train severe test. This upgrade scheme type coating two-component aqueous polyurethane coating of primer, further improved flexibility, adhesion aspects, a surface coating to help train effective against flying stone striking.
Currently, certification Korth Created in collaboration with bright Kewei Ze high hot metal paint products has been basically completed, the two sides will further promote cooperation with rail transportation OEMs and supporting plants, and promote the use of water-based paint on high-speed rail trains. Future, water-based paint industry is going to change direction in the transformation process, the industry chain upstream and downstream enterprises need to work closely together to accelerate product development, testing and application promotion. To this end, Korth Chong Liang Kewei Ze working with other companies to join hands innovative, high-performance water-based coating solution is applied to the wider transport sector, enhance the overall sustainable development of the transport industry.
