    Core tip: a coating standard, the limit of harmful substances in solvent based wood coatings for interior decoration materials, won the first prize of 2007 national standard innovation contribution at the beginning of this year, becoming the only standard in the chemical industry What is the significance of the award of this standard for the coating industry? What are the impacts? Zhao Ling, secretary-general of the China coating and pigment Standardization Committee, the first drafting unit of the standard, expounded her own views It has created the concept of controlling from the source Solvent based wood coatings have always been the mainstream products of furniture coatings Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Home of coatings: a coating standard, the limit of harmful substances in solvent based wood coatings for interior decoration materials, won the first prize of 2007 national standard innovation contribution at the beginning of this year, becoming the only standard in the field of chemical industry What is the significance of the award of this standard for the coating industry? What are the impacts? Zhao Ling, secretary-general of the China coating and pigment Standardization Committee, the first drafting unit of the standard, expounded her own views It has created the concept of controlling from the source that solvent based wood coatings have always been the mainstream product of furniture coatings, containing 50% organic solvents These solvents will eventually evaporate into the atmosphere, causing serious pollution In addition, there are also pollution of synthetic resin residual harmful compounds, pollution caused by the use of heavy metal pigments and pollution of harmful additives These pollutions cause damage to the ecological environment, threat to human health, and are not conducive to the long-term development of the coating industry For a long time, the domestic coating industry has never set a limit standard for harmful substances in coatings Until Changzhou paint Chemical Research Institute of China National Chemical Construction Corporation organized and completed the compulsory national standard GB18581 "limit of harmful substances in solvent based wood coatings for interior decoration materials" in 2001, which was issued and implemented at the end of 2001 At the review meeting organized by the national standards committee, experts concluded that the standard is highly innovative, has Chinese characteristics, has broad market application prospects, and has reached the international advanced level The formulation of the standard reflects the concept of controlling harmful substances in building materials from the source, and has created a precedent in the coating industry The main indexes and test methods have reached the international advanced level Zhao Ling introduced the industry innovation revolution After the implementation of the standard, due to the first compulsory limit of harmful substances in the paint, it has caused great repercussions in the paint industry and even the whole society, bringing unprecedented impact to the paint industry The effect of the implementation of the standard is mainly reflected in the following aspects: to really attract the attention of the coating industry to the harm of volatile organic compounds (VOC), to change the understanding and control of VOC from academic attention to the essence of product quality, to reduce VOC has become the focus and development trend of the industry's technological innovation; to pay attention to the quality control of raw materials and finished products, such as the control of benzene content in xylene, to toxicity Lower solvents replace toluene, xylene, etc In 2001, the content of free toluene diisocyanate (TDI) in most small and medium-sized enterprises failed to meet the limit requirements, with an average of 3%% ~ 4%% However, most of them can meet the standard limit requirements at present The implementation of the standard has led the development direction of environmental protection in the coating industry, and the invention patents related to reducing VOC, free TDI and benzene free products in the coating have increased significantly Since 2002, 29 related patents have been authorized, which has aroused great attention of the industry to the research and development of environmental friendly coatings, such as hundreds of related patents of waterborne coatings The standard also promotes the adjustment of industrial structure, from decentralization to centralized optimization, improves the enthusiasm of enterprises for the research and development of various environmental protection coatings, and promotes the development of low pollution coatings such as powder coatings, solventless coatings, water-based coatings, high solid coatings, etc., resulting in huge resource conservation and environmental protection benefits The new standard has become the basis of social supervision and industry self-discipline, and laid the foundation for the coating industry and related industries to formulate other product standards Since then, the market supervision has laws to follow In the years after the implementation of the standard, the General Administration of quality supervision, inspection and quarantine, the State Administration for Industry and Commerce and the quality supervision departments of all localities organize the supervision and spot check of solvent based wood coatings in accordance with this standard every year AQSIQ also issued a special document to require the technical supervision departments of all regions to take coatings as an important part of the special crackdown on counterfeit building materials According to this standard, the law enforcement of coating products has been strengthened In addition, the national certification and accreditation supervision and Administration Commission has also implemented compulsory product certification (3C certification) for enterprises producing solvent based wood coatings nationwide since May 1, 2004 Compared with the results of spot check published by the state in recent years, the content of all kinds of harmful substances in solvent based wood coatings has been greatly reduced, and the quality of products has been generally improved, which shows that the implementation of this standard is of far-reaching significance for standardizing enterprise management and coating market, protecting human health and atmospheric environment, and promoting the technological progress and healthy development of coating industry The implementation of this standard has also played a strong driving role in the development of other types of coatings towards low pollution dyeing Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
