Green environmental additives should be mainstream of the times

The newly revised Air Pollution Prevention Act puts forth new requirements for the emission and monitoring of organic volatiles (VOC), together with environmentally friendly coatings and their film forming aids, concrete water reducing agents, polysilicon cutting fluids, automotive brake fluids, aviation kerosene antifreeze The growing demand for such products has provided a broad market space and development opportunities for green additives.

In recent years, domestic smog has ravaged large areas. The photochemical reaction of VOCs is an important accomplice in the manufacture of PM2.5. Therefore, in order to reduce haze damage during the “Thirteenth Five-Year Plan”, it is necessary to reduce VOC emissions, and one of the effective ways is to maximize the substitution of environmentally-friendly solvents for traditional toxic and hazardous solvents, and to constantly develop environmentally friendly solvents. New application development.

Green environmental additives should be mainstream of the times

First of all, speeding up the upgrading of paints, environmentally friendly solvents can be an important task. At present, domestic traditional paints still account for more than 60% of the total. In the upper reaches of paint production, such as solvents, film additives, pigments and other raw and auxiliary materials, as well as in the downstream coating process, large amounts of VOCs will be emitted to pollute the atmosphere. Great. During the “Twelfth Five-Year Plan” period, despite the high-profile efforts of the community to increase monitoring and emission control, the “Twelfth Five-Year” development plan of the Chinese paint industry has also vigorously advocated the elimination of toxic and hazardous solvents such as benzene, but it has been trapped by costs and other benefits. The situation is not satisfactory.

Obviously, due to the lack of authoritative deportation and replacement measures, traditional solvents naturally will not easily give up the vested position and interest in the paint. The national government has imposed a 4% consumption tax on paint since February 1, 2015, and has VOC content higher than 420 g/L during the construction process. It will be imposed once again on the basis of the consumption tax already paid for purchased paint. The same tax type. Promoting the upgrading of the paint industry through taxation means that this move will undoubtedly be of great benefit to environmentally friendly solvents.

Second, to meet the requirements of the times, we have continuously introduced new products for fine chemicals. With the rapid development of science and technology, the demand for new chemical materials in the socio-economic related fields is increasing. Large-scale imports are no longer suitable for China's national conditions, and it is not conducive to changing the long-standing trade deficit pattern in China's chemical industry. Therefore, the auxiliary industry should step forward and take up the important task of the times and provide product support.

At present, according to the growth trend of domestic demand, we should actively use the glycol ether solvent as a source to extend and expand downstream. The main research and development fields are: First, concrete water-reducing agent can increase the concrete strength, while reducing the volume of concrete, making the concrete structure Stronger impact resistance, especially suitable for high-level railways, bridges, high-grade highways, airports and other important projects. The second is solar cutting fluid, which can be widely used in polysilicon and monocrystalline silicon in new energy materials. The third is glycol ethers, in which methyl ether can be used as an aviation kerosene antifreeze, and dimethyl ether is an inert solvent used in automotive brake fluids. Fourth, the odor of paint filming additives can promote the upgrading of architectural paints. Global Coatings Network understands that these application areas are full of vitality, especially as the establishment of the AIIB is in operation and the construction of the “One Belt and One Road” is getting better, providing a huge market space for the aforementioned fine chemical new materials.

Again, avoid falling into low-end competition and implementing total control. At present, the total domestic production capacity of glycol ether solvent has exceeded 800,000 tons, and a certain degree of excess capacity has begun to appear. However, the pace of energy expansion did not stop, mainly because of the increase in new production capacity and the expansion of single-unit installations; the former intensified the disorderly competition among regions, which intensified the imbalance between supply and demand.

Therefore, we call for the government departments in the “Thirteenth Five-Year Plan” to lay out scientifically based on the market capacity, and not to condone the production capacity without regard to actual needs. The market forecasting service should be well done, and the total amount control should be implemented on the macro level so as to maintain the organic connection and matching with the downstream. At the micro level, enterprises should abandon the bulk price of low-end bulk products, shift their focus to research and development of new products, meet existing needs, and guide and cultivate new market demands.
