"Building adhesive harmful substances detection and limited requirements" is expected to issue
The occurrence of large-scale cracking, leakage, and even falling off of wounded people due to the quality problems of construction adhesives has abounded. Because chemical building materials are often nicknamed new material titles, the detection methods are relatively lagging, and the regulatory power is relatively weak, which brings opportunities for some fake and shoddy products from the market. The China Adhesives and Adhesive Tape Industry Association Construction Adhesives Committee held a working meeting in Beijing last week to focus on the drafting and formulation of a national mandatory standard for the detection and limitation of hazardous substances in construction adhesives. According to Yang Wei, Secretary General of China Adhesives and Adhesive Tape Industry Association, this mandatory national standard will make clear limits for more than a dozen compounds and indicators, including free formaldehyde, benzene, toluene, xylene, halogenated hydrocarbons, and toluene. Diisocyanate, organotin, bisphenol A, methyl methacrylate, hazardous heavy metals, hazardous fillers (asbestos) and total volatile organics. At the same time, the standard will list the methods for the detection of relevant hazardous substances, and require the construction adhesive products must be marked on the packaging of the name of the above hazardous substances and its highest content. The National Adhesive Standardization Technical Committee Secretary-General Li Xianquan announced the progress of the mandatory national standard at this meeting: he completed the first draft of the standard in July this year and publicly solicited opinions from the public; he finalized the draft in October and entered the review process, and strived as soon as possible Promulgated and implemented. The forthcoming mandatory national standard will undoubtedly bring about unlimited hope for regulating the construction rubber market. However, representatives from the industry's backbone enterprises have heatedly discussed that setting the rules may not be able to achieve a radius, but the key is also to enhance the execution of standards. Huang Chuchu, president of Shenzhen Gu Kangli Chemical Co., Ltd. puts forward: “At present, there are many standards in the construction industry, but there are also many problems and market confusion. The implementation of standards is poor, the cost of violations is very low, and the supervision of various departments is not in place. Serious damage to the interests and health of consumers. Many of the standards are not technical issues, but are not well implemented. Even the best standards, if not implemented, are equivalent to a piece of paper." Wang Wenjun, deputy general manager of Dalian Kaihua New Technology Engineering Co., Ltd., suggested that “Associate has no enforcement power, but as an industry organization, it should mobilize all forces to combine relevant law enforcement agencies and inspection agencies to regulate the market. For some relationships, public safety and human health The important products, the association can come forward to recommend the company with good product quality, can issue certificates to creditworthy companies, can carry out product certification, can establish and properly improve industry access thresholds, etc." Penghe Kai, chairman of Jiangsu Black Pine Adhesives Co., Ltd., said: “There are standards that are not implemented, not only the problems of the construction industry itself, but also the problems of the entire social moral system. It is necessary to call in violative companies from the perspective of ethics and conscience. In recent years, the construction industry has developed too fast, but it is basically in anarchy. At the same time, the construction industry has almost ruined the entire industry." Representatives of Zheng Qingming, president of Evergreen Chemical Group, and others believe that it is important that standards and testing are not synchronized. It is important that the testing organization's platform is established and recognized. Otherwise, there is no point in standard setting. At present, world-class testing organizations are expensive and unprofessional. Yang Lan said that the association will actively recommend excellent enterprises and products for construction adhesives to participate in the national and industrial brand recognition organized by the China Petroleum and Chemical Industry Federation, and assist them to assist the government authorities and relevant agencies to improve detection and supervision methods. Improve the industry's environmental safety and product quality. Governments and relevant organizations around the world have formulated and issued a large number of laws, regulations and standards relating to the environmental protection of adhesives, restricting the content of harmful substances, and the development trend is reflected in the increasingly stringent restrictions, and the limited number of hazardous substances is increasingly To encourage more environmentally-friendly and green-label certification. Domestic construction adhesives have developed rapidly in recent years, but there are common problems in comparison with foreign countries such as small scale and weak quality awareness. Management is chaotic and superiority is not eliminated. The formulation of mandatory national standards marks a strong first step in our country's process of strengthening management methods and improving management methods. The information passed at the meeting also indicated that China will continue to follow up in the areas of improving pest detection methods, establishing and improving market access mechanisms, and strengthening the supervision of production and construction companies in order to support large-scale, standardized management. Enterprises with strong market development capabilities have achieved rapid development, which has enabled the construction adhesive industry to grow in size and quality, achieve a healthy and stable development with safe production, optimized resource allocation, and strong technical input.
