VIGA faucet olupese 
Laipe, the Nanjing Municipal Bureau of Quality Supervision released the results of the 2017 residents’ home improvement products quality spot check, okiki faucets, irin alagbara, irin ri, 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%.
Awọn unqualified oṣuwọn ti taps labẹ 20$ is as high as 85.7%
Tẹlẹ, 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. Lẹhin ti ayewo, 27 batches were qualified and 13 batches were unqualified, pẹlu kan kọja oṣuwọn ti 67.5%.
Nanjing Quality Supervision Bureau classified the test results according to the product source and price range, and the results were eye-catching.
Awọn 40 batches of tap products sampled this time were 20 awọn ipele, 19 batches ati 1 batch sampled from physical stores, awọn iru ẹrọ e-commerce ati awọn ile-iṣẹ iṣelọpọ, leralera. Lára wọn, 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%.
Lati irisi awọn idiyele ọja, awọn kọja oṣuwọn ti awọn ọja ti 70$ and above is 100% (unqualified rate 0%), and the pass rate of products between 20$ ati 70$ ni 85.7% (unqualified rate 14.3%). The pass rate of products between 20$ ati 40$ ni 62.5% (the unqualified rate is 37.5%), ati awọn kọja oṣuwọn ti awọn ọja ti 100 yuan ati isalẹ ni 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 “Selerati e seamic faulet” ati GB 25501-2010 “Limited Value of Faucet Water Efficiency and Water Efficiency Grade”. Lara awọn 13 batches ti unqualified awọn ọja, the unqualified items mainly related to surface corrosion resistance, omi ṣiṣe ite, sisan uniformity ati awọn ohun elo, among which 2 batches of products were detected to exceed the standard of metal pollutant precipitation (adari).
Ni afikun, 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 wakati, 8 wakati, 12 wakati, ati 24 hours at a low temperature of -10°C. Risk monitoring. Lẹhin ti ayewo, 33 batches of faucets meet the standard requirements, with a compliance rate of 82.5%.
Ayẹwo ohun kan ayewo
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, ati awọn kọja oṣuwọn ti yi ise agbese wà 97.5%; 3 batches of flow uniformity were unqualified, ati awọn kọja oṣuwọn ti yi ise agbese wà 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.
②Atako ipata oju
Among the samples sampled this time, 12 batches of surface corrosion resistance were unqualified, ati awọn kọja oṣuwọn ti yi ise agbese wà 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, ṣugbọn tun kan awọn ẹya oriṣiriṣi bii ohun elo, ilana simẹnti, didan ati pretreatment.
③Precipitation of metal pollutants
Among the samples sampled this time, 2 batches of metal contaminants were unqualified, ati awọn kọja oṣuwọn ti yi ise agbese wà 95%. Ojoriro ti awọn idoti irin jẹ ibatan si ilera eniyan, paapaa ikojọpọ asiwaju ninu ara eniyan, 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.

④ Ohun elo
Among the samples sampled this time, 7 batches of materials were unqualified, ati awọn kọja oṣuwọn ti yi ise agbese wà 82.5%. Diẹ ninu awọn ọja lo zinc alloy, a corrosive material whose price is only 1/3 of copper alloy. Ohun elo yi rọrun lati baje, eyi ti ko nikan ni ipa lori irisi, but also reduces the strength of the faucet, causing water leakage and cracking after a period of use. Akawe pẹlu Ejò alloys, 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 (igbeyewo otutu)
This sampling conducted a temperature test, iyẹn jẹ, freezing the water nozzle at -10°C for 4 wakati, 8 wakati, 12 wakati, ati 24 hours to test the sealing performance. Lẹhin idanwo, Lara awọn 40 batches of taps sampled this time, lapapọ ti 7 batches of faucets have leaked in a low temperature environment.
Ni asiko yi, there is no corresponding national standard for the freezing temperature value of faucets. Labẹ awọn ipo deede, 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. Nibẹ ni yio je jijo ni awọn asopọ. Lati fipamọ awọn idiyele, 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.

Imọran onibara
①Avoid buying zinc alloy faucets
Zinc alloy is a corrosive material, so you should avoid this type of product when purchasing a faucet. O le ṣe iyatọ ni ibamu si iho inu ti ọja naa. 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 yuan ga bi 85.7%, and many items that have a greater impact on consumers’ ilera, 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, fifẹ, burning, bottoming, peeling, 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. Nigbati rira, 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 Wo rilara naa
Try turning the handle up, si isalẹ, osi, ati ọtun. 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. San ifojusi si iyatọ awọn ọja ti o lo awọn ohun elo alloy ati awọn pilasitik ẹrọ, ti didara ati igbesi aye iṣẹ ko dara.
⑥ Water saving
The faucet with a bubbler saves water better. Feel the water flow with your hand when purchasing. Awọn asọ ti omi sisan ati ki o ọlọrọ foomu (omi sisan nkuta akoonu) indicate that the bubbler is of better quality.
