Недавно, the Nanjing Municipal Bureau of Quality Supervision released the results of the 2017 residents’ home improvement products quality spot check, укључујући славине, судопере од нерђајућег челика, 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%.
Неквалификована стопа славина испод 20$ is as high as 85.7%
Претходно, 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. Након инспекције, 27 batches were qualified and 13 batches were unqualified, са пролазношћу од 67.5%.
Nanjing Quality Supervision Bureau classified the test results according to the product source and price range, and the results were eye-catching.
Тхе 40 batches of tap products sampled this time were 20 серија, 19 серије и 1 batch sampled from physical stores, платформе за е-трговину и производне компаније, односно. Међу њима, 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%.
Из перспективе цена производа, пролазност производа од 70$ and above is 100% (unqualified rate 0%), and the pass rate of products between 20$ и 70$ јесте 85.7% (unqualified rate 14.3%). The pass rate of products between 20$ и 40$ јесте 62.5% (the unqualified rate is 37.5%), и пролазност производа од 100 јуана и испод је 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 “Ceramic Sheet Sealing Faucet” и ГБ 25501-2010 “Limited Value of Faucet Water Efficiency and Water Efficiency Grade”. Међу 13 серије неквалификованих производа, the unqualified items mainly related to surface corrosion resistance, степен ефикасности воде, уједначеност тока и материјала, among which 2 batches of products were detected to exceed the standard of metal pollutant precipitation (олово).
Поред тога, 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 сати, 8 сати, 12 сати, и 24 hours at a low temperature of -10°C. Risk monitoring. Након инспекције, 33 batches of faucets meet the standard requirements, with a compliance rate of 82.5%.
Анализа предмета инспекције
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, а пролазност овог пројекта била је 97.5%; 3 batches of flow uniformity were unqualified, а пролазност овог пројекта била је 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.
②Површинска отпорност на корозију
Among the samples sampled this time, 12 batches of surface corrosion resistance were unqualified, а пролазност овог пројекта била је 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, али укључује и различите аспекте као што су материјални, процес ливења, полирање и предтретман.
③Precipitation of metal pollutants
Among the samples sampled this time, 2 batches of metal contaminants were unqualified, а пролазност овог пројекта била је 95%. Таложење металних загађивача је повезано са здрављем људи, посебно нагомилавање олова у људском телу, 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.

④Материјал
Among the samples sampled this time, 7 batches of materials were unqualified, а пролазност овог пројекта била је 82.5%. Неки производи користе легуру цинка, a corrosive material whose price is only 1/3 of copper alloy. Овај материјал је лако кородирати, што не утиче само на изглед, but also reduces the strength of the faucet, causing water leakage and cracking after a period of use. У поређењу са легурама бакра, 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 (температурни тест)
This sampling conducted a temperature test, то је, freezing the water nozzle at -10°C for 4 сати, 8 сати, 12 сати, и 24 hours to test the sealing performance. Након тестирања, међу 40 batches of taps sampled this time, укупно 7 batches of faucets have leaked in a low temperature environment.
Сада, there is no corresponding national standard for the freezing temperature value of faucets. У нормалним околностима, 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. Доћи ће до цурења на прикључку. Да би се уштедели трошкови, 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.

①Avoid buying zinc alloy faucets
Zinc alloy is a corrosive material, so you should avoid this type of product when purchasing a faucet. Може се разликовати према унутрашњој шупљини производа. 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. Ако је могуће, 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 јуан је висок као 85.7%, and many items that have a greater impact on consumers’ здравље, 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, пуцање, burning, bottoming, љуштење, 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. Када купујете, 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 Погледајте осећај
Try turning the handle up, надиграти се, лево, и право. 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. Обратите пажњу да разликујете производе који користе легиране материјале и инжењерску пластику, чији су квалитет и век трајања релативно лоши.
⑥ Water saving
The faucet with a bubbler saves water better. Feel the water flow with your hand when purchasing. Меки ток воде и богато пењење (садржај мехурића протока воде) indicate that the bubbler is of better quality.
