News: On the basis of expounding the concept of green coating and the current situation of automobile coating cleaning production regulations, this article recommends that the varieties of green
a car coating
should be developed innovatively during the 13th Five-Year Plan period, and explore ways to strengthen China's automobile
coating
coating industry. Talk about green coating to promote automotive paint, coating green innovation, transformation and upgrading.
China's reform and opening up 30 years, with economic construction as the core to build a large industrial country, become the world's second largest economy, become the world's largest automobile and paint production and marketing country (in 2014 China's auto production and sales of more than 23 million vehicles, the world's first for 6 consecutive years, car production of more than 200 million vehicles, automotive paint consumption of more than 1 million tons), but not strong.
Core technology (products) are not in the hands of products and enterprises weak competitiveness, but also by the introduction of technology, capital development of brother industries (such as high-speed rail, telecommunications, home appliances and nuclear energy, etc.) through digestion and absorption of the introduction of technology, and then innovation, not only master the core technology, combined with national conditions and innovation, occupy the domestic market, but also go abroad, become a competitor to developed countries counterparts;
emissions of energy and pollutants (VOC, CO2, wastewater, waste water, etc.) from automotive coatings are well above the current international average. Most automotive body coating line coating pollution is serious, energy and water consumption, low resource utilization rate, VOC emissions in 100g/m2 or more, each body coating energy consumption and CO2 emissions, water consumption and wastewater emissions are 2 to 3 times the international level, or more. If no longer governed, no longer upgrade, no longer use green car paint and coating technology, will seriously affect the living environment of mankind and the sustainable development of the national economy.
car paint market about 85% by foreign brands, some high-end coatings still rely on imports.
This paper on the implementation of coating clean production regulations to promote automotive paint, coating greening innovation, accelerate transformation and upgrading, strong automotive coatings coating industry to make some discussions for peers and readers.
In 2003, China promulgated the Cleaner Production Promotion Law, but the concept of clean production is not strong, 10 years of GDP went up, the number of haze days in industrially developed areas increased, the Beijing-Tianjin region in 2014 did not meet the national standard of the number of days has reached 57% of the number of days of the year. In order to blue water and blue sky, energy conservation and emission reduction, sustainable development and other times and social requirements, we must strengthen publicity, enhance the concept of clean production and establish the concept of "green coating." The meaning of cleaner production and "green coating" is described below.
Environment Programme (UNEP 1996): "Cleaner production is an innovative idea that continuously applies an environmental strategy of holistic prevention to production processes, products and services to increase productivity and reduce risks to people and the environment.
for the production process, it requires savings in raw materials and energy, the elimination of toxic materials, and the reduction of the amount and toxicity of all waste.
China's Cleaner Production Promotion Act (2003): "Cleaner production refers to the continuous improvement of design, the use of clean energy and raw materials, the use of advanced technology and equipment, improve management, comprehensive utilization measures, from the source to reduce pollution, improve the efficiency of resource utilization, reduce or avoid the production, services and product use of pollutants and emissions, in order to reduce or eliminate harm to human health and the environment." The
"green coating" concept is that the coating pollution is less (VOC, CO2, particulate matter, sewage and waste emissions are less), energy and resource utilization is high, and high quality, high yield and low cost, in line with clean production standards. To this end, each process of the original coating process, each
smearing equipment
further inspection, inspection and optimization, to eliminate waste in the coating process, eliminate invalid operations and value-for-money functions, so that energy and materials as far as possible the best use. That is to say, with the same amount of raw materials and energy, can process more and better products, create a higher output value, and less sewage, to enhance the competitiveness of products and enterprises.
in the new or modified coating line should be in accordance with national regulations and the original level of energy conservation and environmental protection, personalized planning, relying on technological progress to achieve clean coating production standards.
