    For the second consecutive year, three products folded waist "total volatile organic matter
    according to the Shenzhen Municipal Market Supervision Administration released information, in the third quarter of 2018, the Shenzhen Municipal Market Supervision Administration organized the production and sale of architectural decoration coatings in Shenzhen city carried out product quality supervision spot checks. According to the requirements of "Building Decoration Coatings and Adhesive Harmful Substances Limit" (SZJG48-2014), three items such as "Total Volatile Organics" of Architectural Decoration Coatings were tested.
    results showed that 11 batches of samples of "volatile organic compounds" items were found to be non-conforming

    . Among them, a "water-like colored wood transparent primer" (specification model 2.5L/ barrel, labeled production unit "Lanzhou Ketian Environmental Protection and Energy Saving Technology Co., Ltd.", the unit under inspection "Shenzhen Guangming New District Matian Street Water Science And Field Home Materials Museum") "total volatile organic matter, g/L" project was not qualified.
    This is not the first time that water-related science days in the "total volatile organic matter" on the "fold waist", last year, water-related science days three products due to the same problem on the quality of the "black list."
    2018, the Shenzhen Municipal Market Supervision Bureau informed the 2017 Shenzhen small store sales of paint product quality supervision and spot checks. The results show that the three products produced by Lanzhou Cote d'Ath Environmental Protection and Energy Saving Technology Co., Ltd. are not qualified for the "total volatile organic matter" project. The three products are "water-colored wood transparent paint (half-light)" (size model "2.5L/barrel qualified products", production date 2017-07-25), "water-like wood closed primer" (spec model "2.5L/barrel qualified products", production date 2017-02-15), "water-colored wood transparent paint (highlight)" (size model "2.5L/ barrel qualified products", production date 2017-06-05), their "total volatile organic matter" measured values are 394g/L, 441g/L, 441g/L.
    non-conforming products are harmful to human health
    data show that volatile organic compounds are any organic compounds with an initial boiling point below 250 degrees C under the 101.3kPa standard pressure. Volatile organic compounds will produce pollution to the environment, resulting in photochemical pollution and fine particulate matter (PM2.5) pollution, and increase the load of indoor organic pollutants, serious cases will cause headache, sore throat and other symptoms, endangering human health.
    , both national mandatory standards and local standards have put forward limits on the volatile organic compounds of coatings. Reporters inquire, the sampling is based on the Shenzhen local standards "building decoration paint and adhesive harmful substances limit" (SZJG48-2014) content shows that in the "total volatile organic matter" one, wood coating varnish requirements≤200g/L, wood coating color paint requirements ≤150g/L. In accordance with the national mandatory standards of "indoor decoration materials water-based wood coating hazardous substances limit" (GB 24410-2009) "volatile organic compound content" limit value requirements, coatings ≤300g/L.
    in this sampling, did not publish the "total volatile organic matter" measured value. Shenzhen Municipal Market Supervision Bureau said that if the non-conforming samples in accordance with the corresponding categories of mandatory national standards, some products meet the corresponding mandatory national standard requirements, therefore, Shenzhen sales units did not follow up and strictly follow up and implement the technical specifications of the Shenzhen Special Economic Zone requirements of human factors, but also caused the volatile organic compound content of one of the reasons for non-conformity.
    But from the 2018 water nature of the three non-conforming products of the measured value, whether in accordance with shenzhen local standards or national mandatory standards, the measured value of non-conforming products has been much higher than the standard limit requirements. In particular, water-based wood closed primer, water-based wood transparent paint (high-gloss) two products, "total volatile organic matter" measured value is more than twice the maximum value of local standards in Shenzhen, close to the national mandatory standards of the maximum limit requirements of 1.5 times.
    Water-based technology" declared that "volatile only water
    Shenzhen Municipal Market Supervision Bureau said, from the spot check "total volatile organic matter" non-conforming product sample category, most of the unqualified products are solvent-based products, the volatile organic compounds unqualified is mainly part of the paint used excessive organic solvents.
    "water-based technology" as the advantage of water-based science and technology products in this project exceeds the standard limit requirements, can not help but make people question.
    reporter inquired that Lanzhou Kotian Environmental Protection and Energy Saving Technology Co., Ltd. is a subsidiary of Lanzhou Kotian Investment Holdings Co., Ltd. (hereinafter referred to as "Kotian Group"), providing home furnishings, furniture, construction and coating engineering water-based environmental protection series materials. According to the official website of the Science and Technology Group, Kotian Group is engaged in the research and application of "water-based polymer technology" and calls it "water-based technology": "Water-based technology replaces organic solvents with water, eliminating the toxicity of harmful chemicals in polymer materials and environmental pollution from the source." Water-based materials prepared with this technology do not contain benzene, methamphetamine (DMF) and other organic solvents, nor formaldehyde, heavy metals and other harmful chemicals, volatile only pure water, non-toxic taste, green environmental protection. "Kotian Group said that all its products are based on water-based polymer core technology, relying on a full range of water-based environmental protection products to provide non-toxic whole-house customized services.
    , although the material does not contain formaldehyde and other harmful substances, but before that, the water-like two ecological boards have been detected formaldehyde. On August 18, 2017, the Shanghai Municipal Bureau of Quality and Technical Supervision announced the results of monitoring the safety risks of eco-board product quality. Among them, the trademark label is called "water nature science day", the label production enterprise is "Lanzhou Science and Technology Co., Ltd." two ecological board (production date / lot number are "2017.4", the specification model is (2440× Formaldehyde × releases of 1220×18) mm and (2440×1220×7) mm are 0.2mg/L and 0.1mg/L, respectively.
