China exports melamine tableware industry status quo
05 Jan 2018
In recent years, foreign countries have reported on the quality and safety of Chinese melamine tableware, and the impact of the melamine turmoil in the domestic market a few years ago, the safety of melamine tableware is more sensitive. The new "Food Safety Law of the People's Republic of China" has clearly put food contact materials classified as applicable law. In this situation, the melamine tableware national health standards GB9690 "food containers, packaging materials with melamine - formaldehyde moldings, health standards" in 2009 to be revised. The new standard of product testing more stringent, the basic level of the equivalent of the equivalent level of the EU standards, product quality and safety put forward higher requirements. The author analyzes the status quo of exporting melamine tableware industry, identifies the main risks in quality and safety, discusses the risk management measures for exported melamine tableware, and puts forward suggestions for improving inspection and supervision work.
First, melamine tableware industry overview and product advantages
Melamine tableware is an amino molding compound, is one of the chemical synthesis of thermosetting materials, raw materials for the amino molding powder to melamine (melamine) and formaldehyde under certain conditions, the reaction of polymer, and then adding the right amount of wood pulp cellulose Fillers and colorants and other auxiliary materials and made. Amino molding plastic in the 1940s successfully developed in Western countries, the real realization of industrial production in Japan in the 1950s and 1960s, while China's AMC manufacturing industry started from the 1960s. In recent years, the domestic amino molding compound annual output reached 400000 tons, the production capacity ranks first in the world.
My export melamine tableware has the following advantages: First, the export advantage. Due to dietary habits and the low cost of using ceramic tableware in China, domestic melamine tableware is mainly exported. Second, the cost price advantage. Due to its low correlation with petroleum, the cost price of Aminoplast is only 60% -80% of that of petrochemical products downstream, and the price / performance advantage is remarkable. Third, development prospects and advantages. Melamine dinnerware is not brittle, high heat distortion temperature, strong impact strength and flexural strength characteristics, the scope of application gradually expanded to other areas of traditional plastics, coupled with the United States in recent years has developed a treatment of amino plastic waste plastics and Use, fundamentally solve the environmental protection of the amino molding compound. From the perspective of development, melamine materials compared to ceramics, bamboo, metal and other products, in line with environmental protection and sustainable development on the more unique advantages.
Second, the export of melamine tableware risk identification and risk management measures
1. Formaldehyde and melamine migration risk analysis and risk management measures. Melamine tableware exports were the main unqualified projects, foreign projects and the focus of the domestic melamine turmoil are formaldehyde migration exceeded. Formaldehyde migration products have the following sources: First, raw materials. Melamine tableware raw materials for the aldehyde resin and alpha-cellulose mixture, formaldehyde and melamine in the production process according to a strict proportion of polycondensation, curing, mixing, ball milling, drying, after the treatment of the amino molding powder will still exist A small amount of free formaldehyde, which became the factory test formaldehyde migration exceeded the main source. Second, the process. Melamine tableware as a daily necessities, the market circulation is longer and repeated use of the features. If the stability of the aldehyde resin as the main ingredient is insufficient, the product will still be released gradually after being delivered for a period of time and during use. In addition, the amount of melamine migration and the stability of the production environment, especially in the hot season, the instability of the processing environment is more likely to cause high migration of melamine.
As mentioned above, the key process for the control of formaldehyde migration is the molding process, and the main parameters of the molding process are the molding temperature, the molding time and the molding pressure. The molding equipment currently used is basically a numerical control machine. Setting and monitoring of process parameters become two major factors that affect this key point. Parameters should be set to take full account of the flow of raw materials and forming the contradictory unity, different types of products, exhaust regulations, different raw materials of free formaldehyde difference. In short, to meet the product process requirements and based on the established molding pressure, as far as possible the use of lower molding temperature, longer molding time and exhaust times and exhaust time sufficient to make the raw material free Aldehyde is fully released, to ensure that the product of formaldehyde migration to meet the requirements, and after each type of equipment through the first piece of filing, the corresponding process parameters to work instructions to determine the way down. The main problem of key process monitoring is that it is difficult to realize full standardization of production. For example, weighing, preheating, polishing and removing are all manual operations in the molding process. The molding machine operates continuously for 24 hours. The processing cost of the molded workers is verified on a piece- Do not press the operation instructions and good at molding machine parameters have occurred, it will directly affect the quality and safety of the product. Visible, the level of production management directly determines the quality and safety of melamine tableware, which is the current melamine tableware manufacturing industry is an important issue.
Risk management measures: First, increase the supervision of the production process of melamine tableware enterprises, and guide enterprises to continuously improve production management. The supervision of melamine tableware mainly covers the following elements: verification of raw material filing, verification of the first filing, monitoring and control of the effectiveness of key processes, matching of on-site management of human resources with the number of machines and suitability of workshop environment. The second is to increase the effectiveness of sampling, with a focus on high-risk batches of export-sensitive countries, to focus testing items on high-risk safety and health projects, to improve the accuracy of the submission, to ensure the quality and safety of exported melamine tableware, and to reduce foreign investment Notification case.
2. Conditions of use identified risk analysis and risk management measures. Conditions of use is the most important melamine tableware product features, is the premise of its safety. In addition to not being able to get close to naked flames, it can not be used in microwave ovens, to avoid scratches, to pour into basic conditions such as hot oil, and to use temperature, which directly affects the level of melamine migration. Here involves an important difference between domestic and international testing standards. China's national standard GB9690-2009 will be the migration of the immersion conditions uniform set at 60 ℃, 2 hours; the European Commission Directive 2002/72 / EC developed for different temperature products using different immersion test program, for unlabeled use The conditions will be the most stringent conditions for testing, that is, 100 ℃, 4 hours; Japan Showa 36 Ministry of Health Notice No. 370 requires the use of temperature above 100 ℃ immersion conditions 95 ℃, 30 minutes, and below 100 ℃ Soaking conditions used 60 ℃, 30 minutes. In the melamine tableware migration test found that the same immersion liquid, the same immersion time, the simulated liquid temperature has a decisive influence on the amount of migration, especially in the 70 ℃ ~ 95 ℃ there is a sudden jump, soaking temperature above 95 ℃ lead Migration increased significantly, a direct impact on the passing rate of the product.
Risk management measures: First, the reference to food labeling verification methods, the product identification as the field inspection of the main verification items, sampling strictly in accordance with the laws and regulations of the importing country, the use of identification to determine the test conditions. The second is to guide enterprises to raise awareness of self-protection to prevent the use of signs of missing or wrong, resulting in consumer misuse or importing countries to deviate from the actual conditions of the harsh conditions, triggering a negative effect. At present, China has the most complete identification of products lost to Japan. The EU and the United States lose the products with the basic conditions of use identification, while the products in other areas are often missing or inaccurate. guide.
Third, improve the inspection and supervision of the recommendations
1, is to deepen the transformation of inspection and supervision mode, the focus shifted to the supervision of the production process, and effectively guide enterprises to improve production management level, fundamentally improve product quality and safety.
2. It is to enhance the effectiveness of inspection work and shift the focus of routine tests to projects related to safety and health. In particular, the sampling of formaldehyde and melamine migration to high-risk products exported to Europe and Japan is to be strengthened.
3, urging enterprises to establish a quality management system as soon as possible and operate effectively; attaching great importance to producer responsibility and making every effort to eliminate the gap between some enterprises and regulatory requirements.
4. Improve the safety evaluation system and traceability system of raw and auxiliary materials of enterprises; actively construct the regional supervision system of "producing area government is responsible, strict quality control, inspection and quarantine supervision, industry association coordination and social power participation", work together to enhance products Quality level.
5, It is to organize enterprises to carry out domestic and foreign laws and regulations and quality management knowledge training, and effectively improve self-test self-control capabilities to ensure that products meet the requirements of importing countries, technical regulations; guide enterprises to expand their own brand investment and product innovation design, improve product added value, Quality and efficiency "to win the pace.
6, is to step up investigation of enterprises to avoid export inspection efforts. At the same time, enterprises should conscientiously avoid the inspection and quarantine of exports that are not declared as required and set up the concept of operating according to law.
