"Poison glue" dichloroethane exceeded one hundred times

Yangcheng Evening News reporter Lin Yuan reported: “The price of one tonne of dichloroethane is nearly 4,000 yuan, while the price of environmental protection materials is more than 9,000 yuan. Glue producers are driven by profits and choose to use dichloroethane as raw material.” Reports on the 30 “viscous water poisoning” incidents of 30 migrant workers in Guangzhou have caused continued public concern. A well-known glue manufacturer disclosed in an interview with reporters yesterday that the “glue poisoning” culprit, dichloroethane, was used for glue production on a large scale. The content may reach 40%, much higher than the national regulations --- not more than 0.5%.

90% of luggage companies or the use of toxic glue "As far as I know, only less than 10% of the luggage companies use qualified glue. Some of the inferior glue water content of dichloroethane up to 40%." In the glue production industry for more than 20 years Huang Chu told reporters. According to reports, serious poisoning incidents of 1,2-dichloroethane in 2008 prompted the introduction of the new national standard GB18583-2008. The reporters found out that the national standard stipulates that the limit value of 1,2-dichloroethane in solvent-based adhesives (unit: g/kg) is 5 g. This means that the content of dichloroethane in the glue must not exceed 0.5%.

However, huge profits have driven many glue makers to continue to use large amounts of low-cost dichloroethane as raw materials. Huang Chu has filled in an account: As a solvent for glue, the current market price of 1,2-dichloroethane is 3,700 yuan per ton, while the environmentally friendly, nontoxic No. 6 extraction solvent oil is 9,500 yuan per ton. The glue produced using different raw materials costs twice as much!

The cost is low and the price of inferior glue is also lower. According to reports, environmental protection glue is priced at more than ten yuan per kilogram, while inferior glue only sells for a few dollars. According to the market survey conducted by Huang Chuchu, according to the market survey conducted by him, the “toxic glue” has penetrated into 90% of luggage companies, mostly for small workshops.

Glue is only difficult to distinguish due to appearance odor. Yesterday, Huang Chu filling reporters showed a bottle of highly toxic, 5O% dichloroethane added spray adhesive, and nontoxic No. 6 extract solvent oil glue, both Are golden brown (above, Lin Yuan photo). There is almost no difference in appearance. When the reporter tried to smell the glue, he discovered that the poison glue that added dichloroethane was better than the environmentally friendly glue. There was a fragrance similar to sugarcane.

The reporter was informed in the interview that many poison workers all said that the glue they came in contact with had a pungent smell. In this regard, Huang Chu explained that the unpleasant taste is not necessarily dichloroethane, and may be other ingredients in the glue. “It is difficult for non-professionals to judge whether or not the glue is toxic from the appearance and odor. Even if it is a luggage company, it is difficult to determine whether the glue is qualified when purchasing the glue.”

Huang Chuchu pointed out that although China's toxic substance content in adhesives has been issued in 2008, it has almost become a piece of paper from the point of view of regulatory practices in recent years. “In the production process, safety supervision departments are hard to conduct spot checks on glue companies without licenses and licenses, resulting in the widespread use of venom glue in production.”
