How to interpret color coating product standards? See what the professionals say.

In China, the certification bodies to carry out a wide variety of voluntary certification, the use of standards or technical specifications are not uniform, to the certification of production enterprises management system to establish and manage a lot of confusion, law enforcement agencies in the day-to-day law enforcement process is also at a risk. In order to solve this disadvantage, the CPC Central Committee and the State Council put forward "the establishment of a unified green product system" in the General Plan for the Reform of the Ecological Civilization System and the Opinions of the General Office of the State Council on the Establishment of a Unified Green Product Standard, Certification and Marking System. Environmental protection, energy conservation, water conservation, recycling, low carbon, recycling, organic and other products unified integration into green products, the establishment of a unified green product standards, certification, marking and other systems

. By 2020, the initial establishment of system science, open integration, advanced indicators, authority and unified green product standards, certification, marking system, improve laws and regulations and supporting policies, to achieve a class of products, a standard, a list, a certification, a logo system integration objectives. "Relevant research institutions in various industries have prepared green product evaluation standards in accordance with GB/T33761-2017 General Rules for The Evaluation of Green Products. The GB/T35602-2017 Green Product Evaluation Coatings, drafted by CNOOC Changzhou Coatings and Chemical Research Institute Co., Ltd., was released on December 8, 2017 and implemented on July 1, 2018, and is one of the first 13 green product evaluation standards. To help users understand the technical content of the standard correctly, this article will interpret the background and main content of the standard development.
basic requirements are interpreted
basic requirements are divided into the basic requirements of production enterprises and the basic requirements of products. The basic requirements of production enterprises mainly from clean production, technology, safety production, management system, hazardous chemicals safety management, environmental protection and other aspects made specific requirements. If the safe production of an enterprise shall comply with the requirements of the AQ/T9006 Basic Standards for standardization of safe production of enterprises, the safety facilities of construction projects shall conform to the "three simultaneous" system, and the enterprise shall establish and operate a safety management system for hazardous chemicals in accordance with the Regulations on the Safety Management of Hazardous Chemicals. The basic requirements of the product are to provide for the non-addition of hazardous substances and to meet the health and environmental requirements in specific areas. If benzene, methanol, halogenated hydrocarbons, ozone-depleting substances and a series of substances harmful to the ecological environment and human health must not be added to the coating, electrical and electronic coatings meet the GB/T26572-2011 requirements, automotive coatings meet the GB/T30512-2014 requirements.
Index System Interpretation
This standard evaluation index selection follows the principle of high consumer concern, urgent need for consumption upgrading, great ecological environment impact, integration of product green and quality, and dual greenness of products and enterprises in the paint life cycle. This standard evaluation index system is divided into first-level indicators and secondary indicators, the first-level indicators specifically include resource attribute indicators, energy attribute indicators, environmental attribute indicators, quality attribute indicators, secondary indicators are specific evaluation projects. Due to the different types of coatings, the secondary index content and reference value requirements of each type of coating are also different. This standard has formed a water-based building coating index requirements, building inorder powder coating materials index requirements, water-based industrial coatings index requirements, powder coating indicators requirements, radiation curing coating indicators requirements, high solid sub-coatings and solvent-free coatings indicators requirements. The following are mainly included in the six indicator requirements. (1) The resource attribute index GB/T33761-2017 resource attribute index stipulates that the resource attribute focuses on selecting materials and water resources reduction, facilitating recycling, packaging materials and other indicators. This standard resource attribute is selected according to the domestic advanced level requirements of the Clean Production Evaluation Index System (Trial) promulgated in 2007, and the international advanced level requirements of the Clean Production Evaluation Index System for the Coating Industry promulgated in 2016. The main selection of raw material consumption, fresh water consumption and raw material production enterprises clean production requirements as a secondary indicator. In addition, combined with foreign green product standards, water-based construction and water-based industrial coatings because of the organic compounds added to their resins will cause certain harm to the human body and the environment, so the control of the content of such organic compounds in products as a secondary indicator of such coatings supplementary projects, such as the control of residual monosome, benzene, toluene, N-methylphenidate content. (2) Energy attribute index GB/T33761-2017 Energy attribute index specifies that energy attributes focus on selecting energy conservation and energy efficiency indicators for products in the manufacturing or use process. The selection of energy attributes of this standard is also based on the domestic advanced level requirements of the Clean Production Evaluation Index System (Trial) promulgated in 2007, and the international advanced level requirements of the Clean Production Evaluation Index System for the Coating Industry promulgated in 2016. Considering the characteristics of the coating industry, this standard only selects the comprehensive energy consumption per unit of product as a secondary indicator. (3) Environmental attribute indicator GB/T33761-2017 Environmental attribute index specifies that environmental attributes focus on the selection of production process pollutant emissions, the use of toxic and harmful substances release indicators. This standard mainly selects the following 4 points requirements as secondary indicators. a. Whether the enterprise site is installed in line with the requirements of particulate recovery device, and normal operation. b. Whether to install the required local or overall closed exhaust collection device, collect and enter the closed negative pressure exhaust gas treatment system, and normal operation. c. Pollutant emissions comply with national or local pollutant emission standards and enforcement requirements. d. Volatile organic matter content requirements in the product. Among them, the product volatile organic matter content requirements are based on reference to Europe, the United States, Japan, Hong Kong, China and other standards, the development of China's paint green product evaluation benchmark value, the standard volatile organic matter content benchmark value is higher than the foreign indicator requirements. (4) Quality attribute indicator GB/T 33761-2017 quality attribute index specified quality attributes focus on selecting high consumer concern, affecting high-end quality product durability, health and safety indicators. This standard first selects the product quality performance meets the highest level requirements of quality standards as a secondary index item, secondly, selects formaldehyde, benzene, toluene, ethyl benzene, xylene, heavy metals, biological killers and other substances that are harmful to human health and the environment as a secondary index item; As a necessary product for interior decoration, the amount of harmful substances released after coating is the focus of residents' attention, so the total volatile organic matter and formaldehyde release as a secondary index item;
