VIGA 수도꼭지 제조업체 
최근에, the Nanjing Municipal Bureau of Quality Supervision released the results of the 2017 residents’ home improvement products quality spot check, 수도꼭지 포함, 스테인레스 스틸 싱크, bathroom brackets and paint-free boards. The pass rate of faucets is the lowest at 67.5%, and the pass rate of faucets priced at 100 yuan and below is only 14.3%.
자격이없는 탭 비율 20$ is as high as 85.7%
이전에, the Nanjing Municipal Bureau of Quality and Technical Supervision commissioned the Nanjing Product Quality Supervision and Inspection Institute to conduct random inspections on 40 batches of faucet products sold by production enterprises, circulation areas and e-commerce platforms in Nanjing. 검사 후, 27 batches were qualified and 13 batches were unqualified, 패스 속도로 67.5%.
Nanjing Quality Supervision Bureau classified the test results according to the product source and price range, and the results were eye-catching.
그만큼 40 batches of tap products sampled this time were 20 배치, 19 배치 및 1 batch sampled from physical stores, 전자 상거래 플랫폼 및 제조 회사, 각기. 그중, the qualification rate of physical store products is the lowest at 55%; the qualification rate of e-commerce platform products is 78.9%; and the qualification rate of production enterprises is 100%.
제품 가격의 관점에서, 제품의 통과율 70$ and above is 100% (unqualified rate 0%), and the pass rate of products between 20$ 그리고 70$ ~이다 85.7% (unqualified rate 14.3%). The pass rate of products between 20$ 그리고 40$ ~이다 62.5% (the unqualified rate is 37.5%), 그리고 제품의 패스 속도 100 위안과 아래는입니다 14.3% (the unqualified rate is 85.7%).
2 batches of faucet metal pollutants precipitation exceeded the standard
This sampling inspection was carried out in accordance with GB 18145-2014 “세라믹 시트 밀봉 수도꼭지” 그리고 GB 25501-2010 “Limited Value of Faucet Water Efficiency and Water Efficiency Grade”. 중 13 자격이없는 제품의 배치, the unqualified items mainly related to surface corrosion resistance, 물 효율 등급, 흐름 균일 성과 재료, 그 중 2 batches of products were detected to exceed the standard of metal pollutant precipitation (선두).
게다가, this sampling inspection also refers to the standard of QB/T 1334-2013 “General Technical Conditions for Faucets”, and carried out the sealing performance of the faucet after freezing for 4 시간, 8 시간, 12 시간, 그리고 24 hours at a low temperature of -10°C. Risk monitoring. 검사 후, 33 batches of faucets meet the standard requirements, with a compliance rate of 82.5%.
검사 항목 분석
①Flow uniformity and water efficiency grade
Flow uniformity and water efficiency grade Among the samples sampled this time, 1 batch of water efficiency grade was unqualified, 그리고이 프로젝트의 패스 속도는있었습니다 97.5%; 3 batches of flow uniformity were unqualified, 그리고이 프로젝트의 패스 속도는있었습니다 92.5%. These two items are the requirements for the energy efficiency of the water tap, and the uniformity of the flow is the prerequisite for evaluating the water efficiency grade of the tap. Excessive flow of water nozzles will cause waste of water resources, which is not conducive to the implementation of my country’s energy conservation and emission reduction policies.
표면 부식 저항
Among the samples sampled this time, 12 batches of surface corrosion resistance were unqualified, 그리고이 프로젝트의 패스 속도는있었습니다 70%. Products with unqualified surface corrosion resistance are prone to rust during use, which will not provide protection and affect the appearance and use of the product. The surface corrosion resistance of the faucet not only depends on the company’s electroplating process, 또한 재료와 같은 다양한 측면도 포함됩니다, 캐스팅 과정, 연마 및 전처리.
③Precipitation of metal pollutants
Among the samples sampled this time, 2 batches of metal contaminants were unqualified, 그리고이 프로젝트의 패스 속도는있었습니다 95%. 금속 오염 물질의 강수량은 인간 건강과 관련이 있습니다., 특히 인체에 납이 축적됩니다, which can cause long-term health risks in the human body and affect the normal physiological functions of the human body. The low-grade copper grades of faucet products and the substandard production process of the enterprise are all causes of excessive precipitation of metal pollutants.

material
Among the samples sampled this time, 7 batches of materials were unqualified, 그리고이 프로젝트의 패스 속도는있었습니다 82.5%. 일부 제품은 아연 합금을 사용합니다, a corrosive material whose price is only 1/3 of copper alloy. 이 자료는 부식하기 쉽습니다, 외관에 영향을 줄뿐만 아니라, but also reduces the strength of the faucet, causing water leakage and cracking after a period of use. 구리 합금과 비교합니다, zinc alloys are cheap and easy to process. In order to control costs and reduce processing links, some companies use zinc alloys instead of copper alloys to make greater profits.
⑤ Risk items (온도 테스트)
This sampling conducted a temperature test, 그게, freezing the water nozzle at -10°C for 4 시간, 8 시간, 12 시간, 그리고 24 hours to test the sealing performance. 테스트 후, 중 40 batches of taps sampled this time, 총 7 batches of faucets have leaked in a low temperature environment.
현재, there is no corresponding national standard for the freezing temperature value of faucets. 정상적인 상황에서, the faucet will not be frozen and cracked at a few degrees below zero, but after low-temperature freezing, due to the expansion and condensation of water in the valve core, the valve core will be squeezed and stressed. 연결에 누출이 발생합니다. 비용을 절약하기 위해, some manufacturers use poor-quality brass as the casting material for the faucet. The ductility of the metal is greatly reduced, and it is easy to freeze at low temperatures and almost breaks when it is knocked.

소비자 조언
①Avoid buying zinc alloy faucets
Zinc alloy is a corrosive material, so you should avoid this type of product when purchasing a faucet. 제품의 내부 공동에 따라 구별 될 수 있습니다.. Copper materials are generally castings, and the inner wall of the product is not very flat, while zinc alloys are injection-milled, the inner wall will be very smooth, and the inner wall has obvious separation lines. If possible, you can grind away the sample in an inconspicuous place to see the color. The color of zinc alloy is white, while copper alloy is yellow.
②Avoid buying low-cost faucets
The unqualified rate of faucets below 100 위안은 높습니다 85.7%, and many items that have a greater impact on consumers’ 건강, such as the precipitation of materials and metal pollutants, are not recommended.
③Look at the surface
Visually check whether the plating surface of the faucet is evenly glossy, and pay attention to whether there are any defects such as peeling, 열분해, burning, bottoming, 필링, dark spots and obvious pitting. The sprayed surface structure should be fine, smooth and uniform, without defects such as sagging and bottoming. There is no burr or grit to the hand.
④Look at the thread
The pipe thread of the faucet is connected with the connecting hose or pipe. 구매할 때, visually check the thread surface for defects such as dents and broken teeth. Pay special attention to the effective length of the pipe thread.
⑤ 느낌을보세요
Try turning the handle up, 아래에, 왼쪽, 그리고 맞습니다. If it feels light and does not feel blocking, the valve core is better. The main parts of a good quality faucet are made of brass. 합금 재료 및 엔지니어링 플라스틱을 사용하는 제품을 구별하기 위해주의하십시오., 품질과 서비스 생활은 상대적으로 열악합니다.
⑥ Water saving
The faucet with a bubbler saves water better. Feel the water flow with your hand when purchasing. 부드러운 물 흐름과 풍부한 거품 (물 흐름 거품 함량) indicate that the bubbler is of better quality.
