High-toxic paint is strictly used by environmental protection products
In July of this year, the State Administration of Work Safety issued a notice on controlling the hazardous substances of wood furniture companies. At the same time, waterborne wood coatings were included in the “Environmental Economic Policy Supporting Comprehensive List of 2010†as environmentally friendly products. The country’s express restrictions on highly toxic solvent-based wood coatings and the support of environmental and economic policies have made the water-based painters who have been struggling for more than 10 years to see the light. The reporter recently interviewed experts in the industry. They believe that in view of current policies and market conditions, wood coatings will usher in a period of great change. The spring of the development of the waterborne wood coatings industry has really arrived.
At present, the annual dosage of wood coatings in China is more than 800,000 tons, of which solvent-based paints account for about 98%, water-based paints account for about 2%, and total VOC (volatile organic compound) emissions are more than 500,000 tons. In solvent-based wood coatings, nitro coatings account for about 1/4, and organic solvents contain up to 72%. These coatings not only endanger the health of workers due to the volatilization of many solvents during the coating process, but also cause serious environmental pollution and huge waste of petroleum resources. Nearly 80% of China’s furniture is wooden furniture and exports rank first in the world. According to statistics of the General Administration of Customs, the export value of furniture and parts in China reached 25.33 billion US dollars in 2009. Almost all of these furniture were sprayed with solvent-based paint. The products were exported to foreign countries and pollution was left in the country.
After more than ten years of technical breakthroughs and product development, waterborne wood coatings in China have become more mature and have a wide range of conditions for promotion. Over the years, the industry has been calling for all parties to support the promotion and application of waterborne wood coatings, but the promotion of waterborne wood coatings has been rather slow. There are many reasons for this, such as the cost of waterborne coatings, market awareness, gaps between national and industrial standards and foreign countries, and the differences in performance with solvent-based coatings, but the biggest resistance comes from furniture factories. The use of waterborne wood coatings must install new drying equipment, increase drying time, and increase costs.
The State Administration of Work Safety of the State Administration of Construction Supervision and Testing Organization found that the highly toxic substance hazards of wood furniture manufacturing enterprises detected that the chemical poisons exceeded the standards seriously, especially the highest levels of benzene, formaldehyde, aniline and ** diisocyanate were 121.5, 116.0, and 130.1 times respectively. 3.1 times. To this end, the State Administration of Work Safety issued the "Notice on Developing Harmful Treatment of Highly Hazardous Substances in Wood Furniture Manufacturing Enterprises" in July, requiring wood furniture manufacturers to adopt non-toxic or low-toxic paints and adhesives to reduce them from the source. Highly toxic substances. The "Notice" also requires that wooden furniture manufacturing enterprises should seriously carry out high-risk pollution control and the transformation of protective facilities. If they do not meet the requirements, they will have to suspend production until they are shut down. The introduction of this policy will undoubtedly be of great benefit to the waterborne wood coatings industry.
Another news also boosted the confidence of painters. Waterborne wood coatings as environmental friendly products have been listed by the Ministry of Environmental Protection as an environmental friendly product by the experts and relevant ministries and commissions, and are provided to various economic departments. Previously, water-based wood coatings as high-performance, water-based functional coatings and additives were included in the "National high-tech fields supported by the country", according to which can apply for recognition of high-tech enterprises to obtain priority and apply for corporate research and development costs before the deduction. At the just-concluded waterborne wood coatings environmental economic policy promotion seminar, the delegates proposed policies to encourage the development of waterborne wood coatings, limit the production and use of solvent-based wood coatings, and report to the relevant national departments.
Some companies have first promoted waterborne wood coatings. In an interview with reporters, Duan Gang, Asia Pacific Technical Director of Guangdong Huarun Paint Co., Ltd., said that China Resources gained valuable experience by changing the production line from nitro coating to water-based coating through full involvement in the furniture factory. From the entire process, there is little or no increase in raw material transformation costs. Because with the continuous rise in the price of oil, the price of thinner is also increasing. If you change to water-based paint, this part of the cost will be gone. At the same time, the conversion efficiency of water-based paints is high and the waste of raw materials is reduced In addition, some furniture factories not only transformed the raw materials, but also changed the coating line. This changed the original coating method, which greatly reduced the amount of paint used. He said that light-curing coatings have developed rapidly abroad and are a good solution to the current lack of performance of water-based paints. He also suggested setting up a national-level coating application research center to establish a training center and demonstration unit to better utilize resources and promote the development of the industry.
In order to accelerate the development of the waterborne wood coatings industry, Shen Hao, a senior expert in coating industry, suggested that an expert group be established nationwide to provide technical services for companies that will transform waterborne coatings into solvent coatings; and establish waterborne wood coating test centers to help enterprises Product testing; Organization experts to accept a number of waterborne wood coating products, to speed up its promotion and application; Absorption of foreign cooperation units to accelerate the promotion and application of waterborne wood coatings; Preparation of waterborne wood coating standards suitable for China's national conditions.
