Pearl River Delta: high volatile coatings will be launched into the historical stage

Recently, the 12th meeting of the "Guangdong Hong Kong Sustainable Development and environmental protection cooperation group" ...

Recently, the 12th meeting of the "Guangdong Hong Kong Sustainable Development and environmental protection cooperation group" was held in Guangzhou. The two sides assessed the implementation results of air remediation jointly from 2002 to 2010, and established the air emission reduction targets for the two regions in the next 8 years.
According to relevant data, the total amount of sulfur dioxide, nitrogen oxide, PM10 and VOC emitted in the Pearl River Delta in 2010 is nearly 3 million tons. In addition to other pollutants such as PM2.5, the air pollutants emission in the Pearl River Delta in one year is more than 3 million tons.
It is reported that VOC emission industries mainly include furniture, printing, surface coating automobile manufacturing, shoe making, etc. "Pearl River Delta is a traditional gathering area of printing, coating, furniture manufacturing, shoe making and other industries, which contribute a lot to VOC emissions; in recent years, the rapid development of petrochemical and automobile manufacturing industries in the Pearl River Delta has also effectively increased the total VOC emissions." The relevant head of Guangdong Provincial Environmental Protection Department said. Therefore, the Pearl River Delta is speeding up the development of VOC industry emission standards, increasing the control of domestic sources emissions, and gradually prohibiting the sale and use of high-volatile paint and paint.
In other words, the State Council issued the industrial transformation and upgrading plan 2011-2015, and clearly proposed the key tasks of industrial transformation and upgrading, among which is "enhancing independent innovation ability and promoting green and low-carbon development of industry". Green and low carbon development seems to be one of the important indicators of air emission.
From the perspective of economic development and coating industry, high volatile coatings have become the object of common anger. At the beginning of this year, PM2.5 incident became the focus of the national media, and their concern was the space emission reduction problem, and high volatile paint was one of the problems to be rectified.
As the birthplace of Chinese coatings, the Pearl River Delta is one of the contributors to VOC emission of coatings. It is understood that the coating production in the Pearl River delta accounts for 27% - 28% of the national coating production. According to the relevant data released in the 12th Five Year Plan Environmental Protection Development Plan of China coatings industry, solvent coatings accounted for 52.1% in 2009, and solvent coatings are the main source of VOC emission.
With the development of economy and social progress, the high pollution emission caused by the backward coating technology has become one of the important factors to balance the social progress. According to a person in charge, taking traditional paint as an example, about 70% of the content is organic solvents. These solvents are extracted from oil or coal and evaporated to the air. In 2011, the amount of paint in China was 11 million tons, which means nearly 7 million tons of organic solvents evaporated into the air, causing serious resource waste.
Although there are no laws and regulations on low VOC emission in China, there will be relevant standards in each province, among which Guangdong Province is the pioneer province. In 2006, due to the lack of formal coating Park and paint related standards, Shunde paint industry was in chaos. Then Shunde paint gradually planned to transfer to chemical industrial parks in North Guangdong and Huizhou. No matter what the effect, at least the transfer of paint industry can achieve unified management and more strict monitoring of air emission.
While the industry transfer is in progress, the coating industry in Pearl River Delta is still upgrading, gradually eliminating the backward coating technology, and developing coatings suitable for the times and consumers. Up to now, many formaldehyde free coatings, children's coatings, green environmental protection coatings have come out. In the furniture industry, the relevant regulations are issued, the relevant index is more strict, and the requirements for furniture coatings are also higher and higher. As one of the "three board axes" of Pearl River Delta coating, wood coatings have always been the market development point that Guangdong paint attaches importance to. Many coatings have gradually increased the research and development of furniture coatings, such as Jiabaoli, meticulus, bards and other coatings.
In addition, not only the coatings are constantly "upgrading", but the government departments are also constantly building a good environment for the healthy development of the coating industry. According to the 12th Five Year Plan, the coatings industry also proposes to improve the access conditions and improve the market access system, so as to promote the healthy development of the coating industry to the low pollution dyeing direction: "the establishment of production enterprises with annual production below the scale of 2000 tons is limited, and the entry threshold of environmentally friendly coatings can be lowered appropriately"; "Shut down a batch of non-standard small-scale workshop enterprises, and gradually eliminate small enterprises with annual output less than 2000 tons"; and "focus on supporting a batch of medium-sized production enterprises with good technical and technological equipment conditions and annual output of more than 10000 tons".
"Guangdong Province has formulated the 12th Five year plan until 2015, and Guangdong water-based coatings will account for 40% of Guangdong's total paint production," said Ms. Huang Kai, Secretary General of Guangdong Coatings Industry Association. However, this is less than 10% of the total. The road to replace high volatile coatings is still long. "
