Faucets are also called faucets. In addition to quality indicators such as water saving, bezpieczeństwo, 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. Tam są 15 production companies involved, and the places of production include Shanghai, Zhejiang, Guangdong, Fujian i inni 4 miejsca. Tam są 15 batches of unqualified batches, and the batch unqualified rate is 100%. Among the unqualified products, wszystkie elementy “wymagania higieny materiału” nie posiadali kwalifikacji, 14 partie “odporność na korozję powłoki i poszycia” elementy nie były zakwalifikowane, I 10 partie “cechowanie” elementy nie były zakwalifikowane.
Niewykwalifikowany “wymagania higieny materiału” oznacza, że metale ciężkie są powszechnie uznawane za przekraczające normę, co zaszkodzi zdrowiu konsumentów. Kontrola wykazała, że wśród produktów objętych próbą tym razem, 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. Po drugie, products with unqualified “odporność na korozję powłoki i poszycia” are easy to rust after use. In addition to affecting the appearance, they may contain toxic components after corrosion. Na przykład, patina has strong toxicity.
