Faucets are also called faucets. In addition to quality indicators such as water saving, seguridad, and beauty, the amount of heavy metal precipitation in faucets has become a health and safety indicator that people are most concerned about. The Zhejiang Provincial Bureau of Quality and Technical Supervision recently spot-checked faucet products and found that the unqualified rate was 100%, and the risk of heavy metals exceeding the standard was high.
Zhejiang Provincial Quality Supervision Bureau and Ningbo Quality Inspection Institute recently conducted a special supervision and spot check on the quality of faucets in Yongkang Hardware City. Hay 15 production companies involved, and the places of production include Shanghai, Zhejiang, Cantón, Fujian y otros 4 lugares. Hay 15 batches of unqualified batches, and the batch unqualified rate is 100%. Among the unqualified products, todos los artículos de “Requisitos de higiene material” no estaban calificados, 14 lotes de “resistencia a la corrosión del revestimiento y enchapado” los artículos no estaban calificados, y 10 lotes de “calificación” los artículos no estaban calificados.
No cualificado “Requisitos de higiene material” significa que se sabe comúnmente que los metales pesados exceden el estándar, que perjudicará la salud de los consumidores. La inspección encontró que entre los productos muestreados esta vez, zinc alloy materials were used as the main material of the products actually accounted for 50%. Zinc itself is a heavy metal, and excessive amounts can cause zinc fever. En segundo lugar, products with unqualified “Resistencia a la corrosión de revestimiento y revestimiento.” are easy to rust after use. In addition to affecting the appearance, they may contain toxic components after corrosion. Por ejemplo, patina has strong toxicity.
