Faucets are also called faucets. In addition to quality indicators such as water saving, sikkerhed, 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. Der er 15 production companies involved, and the places of production include Shanghai, Zhejiang, Guangdong, Fujian og andre 4 steder. Der er 15 batches of unqualified batches, and the batch unqualified rate is 100%. Blandt de ukvalificerede produkter, alle varer af “Krav til materialehygiejne” var ukvalificerede, 14 partier af “korrosionsbestandighed af belægning og plettering” genstande var ukvalificerede, og 10 partier af “markering” genstande var ukvalificerede.
Ukvalificeret “Krav til materialehygiejne” betyder, at tungmetaller almindeligvis er kendt for at overskride standarden, hvilket vil skade forbrugernes sundhed. Inspektionen fandt, at blandt de produkter, der blev prøvet denne gang, 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. For det andet, products with unqualified “belægning og plettering korrosionsbestandighed” are easy to rust after use. In addition to affecting the appearance, they may contain toxic components after corrosion. For eksempel, patina has strong toxicity.
