Shandong Coating Association

In the organization of Shandong coating industry, enterprise leaders and related industries, I watched and studied the 2020 China International Coating conference held in the form of online conference from April 9 to 10, which has produced great repercussions in Shandong coating industry and achieved very good results.

Due to the epidemic situation, some of our meetings this year may adopt the mode of network meeting. The successful holding of this meeting shows us a new mode of meeting, which is of great reference significance. It is understood that Gu Shigang, general manager of Shandong Pentium paint Co., Ltd., attaches great importance to this meeting and specially issues a notice of watching, requiring all departments to organize all staff to study and watch it The grand occasion of China International Coatings Conference, at the same time, write the impressions combined with their own practical work. Among them, we focus on several issues; under this year's epidemic situation, has environmental protection management been relaxed? What are the new policies and changes in environmental governance?

The emergency management and control of heavy pollution weather in autumn and winter 2019 has a serious impact on the coating and coating industry in our province, so does the policy change in 2020? What should we do in advance? What is the future development direction of coating enterprises?

The experts and leaders at the meeting gave us an interpretation of coating online coatingol.com. Next, I will review the key points of the meeting around the speeches of several leaders and experts. 1、 On the control of heavy pollution weather (several principles): 1. Encourage source control (i.e. optimize product structure) encourage enterprises to produce or use low VOC products (in line with technical requirements for coating products with low VOC content or water-based coating products in line with national standards) instead of producing high VOC products, and plan according to the proportion of low VOC products in total products Sub enterprise level; 2. Encourage advanced production process and equipment - to achieve airtight in coating production to improve VOC collection efficiency; 3. Encourage implementation of refined management - improve production automation level and reduce unorganized emissions; 4. Encourage installation of efficient end treatment equipment - use RTO technology or zeolite wheel concentration + RTO technology to process VOC; 5 Encourage clean transportation - enterprises use low pollution and low emission vehicles to transport raw materials and products; 6. Emission reduction measures - coating production and coating application Enterprises: through the above points, we understand the principles, requirements and characteristics of heavy pollution weather performance rating, and we can take emission reduction measures in advance according to the above description. 2、 Change of heavy pollution rating in 2020 - encourage better enterprises and reward the good and punish the bad: the performance rating in 2020 is more reasonable and detailed than that in 2019. On the basis of meeting the product requirements of low VOC, unorganized emission requirements and coating emission standard requirements, some preferential policies are given to better benchmarking enterprises; thirdly, the technical requirements for coating products with low VOC content has been issued recently, which will have a huge impact on the construction and use of the coating industry.

1. Win the blue sky and protect the blue sky The definition of "high VOCs content solvent coating" in the important clause of the three-year action plan of weizhan "Prohibition of construction, production and use of high VOCs content solvent coating in key areas" will be based on the formulation and promulgation of the standard "technical requirements for low VOC content coating products".

2. For the process of using coating with low VOCs content, the state has introduced important encouraging measures, reflecting the new change of VOCs emission end treatment requirements. (1) . if the VOCs content (mass ratio) of raw and auxiliary materials used by the enterprise is lower than 10%, unorganized emission collection measures are not required. (2) . if the enterprise adopts the coating that conforms to the relevant national regulations on products with low VOCs content, the emission concentration is stable and meets the standards, and the emission rate and emission performance meet the relevant regulations, the corresponding production process may not require the construction of end treatment facilities. (3) . after using the coating specified for products with low VOC content, even if the initial emission rate of NMHC in the collected exhaust gas is high (general area ≥ 3000kg / h; key area ≥ 2000kg / h), the decontamination efficiency must reach 80%, only the emission concentration can reach the standard.

3. Basic requirements: mandatory standard "requirements for VOCs content limit in hazardous substance limit" -- red line, green requirements: recommended standard "technical requirements for coating products with low VOCs content" -- green line,

4. "Technical requirements for coating products with low VOC content" has different technical requirements for different types and fields of coating products, and now it has been established The fields of mature low VOC substitute products have been reflected in the standard, while the fields of immature products have not been listed. Solvent based high solid coatings have also been included in the scope of low VOCs coating products. "Technical requirements for coating products with low VOCs content" actually provides us with a plan, which tells us which types of products should be used in different fields to achieve the goal of source emission reduction.
