The random inspection was conducted in accordance with the requirements of the mandatory national standard GB18583-2001 "Restriction of harmful substances in interior decoration materials and adhesives", and the items of free formaldehyde, benzene, toluene + xylene, toluene diisocyanate, total volatile organic compounds of adhesive products were carried out. Inspection. After inspection, the quality of products produced by large-scale enterprises with relatively high market share is good, and all the items inspected meet the requirements set by national standards.
The main quality problem found in random inspections is that the free formaldehyde or benzene content of individual products is excessive. Formaldehyde is a toxic substance that is colorless and has a strong irritating odor. Benzene is a colorless liquid with a special aromatic odor. It is a flammable and highly toxic substance that is highly volatile at room temperature. The mandatory national standard GB18583-2001 "Limits for harmful substances in interior decoration materials adhesives" stipulates that the benzene content of adhesive products is ≤ 5g/kg. There were individual products that were found to have unqualified levels of free formaldehyde and benzene, and one of them had a benzene content of 506 g/kg, more than 100 times the mandatory national standard requirements.
Regarding the main quality problems found during spot checks, the AQSIQ has instructed all local quality and technical supervision departments to strictly comply with the provisions of relevant laws and regulations such as the product quality law, and dealt with enterprises that failed product quality inspections according to law and rectify them within a time limit. At the same time, it will intensify publicity efforts and guide consumption in quality-checked companies. The AQSIQ will continue to conduct follow-up inspections on the quality of adhesive products to promote the improvement of the overall quality level of the adhesive industry.
