VIGA Faucet Manufacturer 
Kwanan nan, the Nanjing Municipal Bureau of Quality Supervision released the results of the 2017 residents’ home improvement products quality spot check, ya shafi famfo, bakin karfe sakints, 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%.
Da rashin daidaituwa na taps 20$ is as high as 85.7%
A baya, 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. Bayan dubawa, 27 batches were qualified and 13 batches were unqualified, tare da wucewar pass na 67.5%.
Nanjing Quality Supervision Bureau classified the test results according to the product source and price range, and the results were eye-catching.
The 40 batches of tap products sampled this time were 20 birches, 19 batura da 1 batch sampled from physical stores, kamfanonin kasuwanci da kamfanonin masana'antu, bi da bi. Tsakanin su, 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%.
Daga hangen farashin kaya, da wucewar kayayyakin 70$ and above is 100% (unqualified rate 0%), and the pass rate of products between 20$ kuma 70$ ne 85.7% (unqualified rate 14.3%). The pass rate of products between 20$ kuma 40$ ne 62.5% (the unqualified rate is 37.5%), da kuma wucewar kayayyakin 100 yuan da ƙasa yana 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 “Akwatin Ceramic” da gb 25501-2010 “Limited Value of Faucet Water Efficiency and Water Efficiency Grade”. Daga cikin 13 Bats na samfuran da ba a daidaita ba, the unqualified items mainly related to surface corrosion resistance, Ingancin ruwa, Gudummawar gudummawa da kayan aiki, among which 2 batches of products were detected to exceed the standard of metal pollutant precipitation (kai).
Bugu da kari, 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 sa'ad da, 8 sa'ad da, 12 sa'ad da, kuma 24 hours at a low temperature of -10°C. Risk monitoring. Bayan dubawa, 33 batches of faucets meet the standard requirements, with a compliance rate of 82.5%.

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, da kuma wucewar wannan aikin ya kasance 97.5%; 3 batches of flow uniformity were unqualified, da kuma wucewar wannan aikin ya kasance 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.
②surface ②surface juriya
Among the samples sampled this time, 12 batches of surface corrosion resistance were unqualified, da kuma wucewar wannan aikin ya kasance 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, Amma kuma ya ƙunshi fannoni daban-daban kamar kayan, Tsarin jefa kuri'a, polishing da predatest.
③Precipitation of metal pollutants
Among the samples sampled this time, 2 batches of metal contaminants were unqualified, da kuma wucewar wannan aikin ya kasance 95%. Matsakaicin zubar da ƙarfe yana da alaƙa da lafiyar ɗan adam, Musamman ma tara kai a jikin mutum, 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.

Karyara
Among the samples sampled this time, 7 batches of materials were unqualified, da kuma wucewar wannan aikin ya kasance 82.5%. Wasu samfurori suna amfani da zinc sily, a corrosive material whose price is only 1/3 of copper alloy. Wannan kayan yana da sauki ga Corrode, wanda ba kawai ya shafi bayyanar ba, but also reduces the strength of the faucet, causing water leakage and cracking after a period of use. Idan aka kwatanta da murfin ƙarfe, 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 (gwajin zazzabi)
This sampling conducted a temperature test, wato, freezing the water nozzle at -10°C for 4 sa'ad da, 8 sa'ad da, 12 sa'ad da, kuma 24 hours to test the sealing performance. Bayan gwaji, Daga cikin 40 batches of taps sampled this time, jimlar 7 batches of faucets have leaked in a low temperature environment.
A halin yanzu, there is no corresponding national standard for the freezing temperature value of faucets. A karkashin yanayi na al'ada, 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. Za a yi Lafiya a cikin haɗin. Don adana farashi, 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. Ana iya rarrabe shi bisa ga ramin ciki na samfurin. 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 yana da girma kamar 85.7%, and many items that have a greater impact on consumers’ lafiya, 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, fatashin, burning, bottoming, kwasfa, 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. Lokacin siye, visually check the thread surface for defects such as dents and broken teeth. Pay special attention to the effective length of the pipe thread.
Dubi ji
Try turning the handle up, sauka, na hagu, kuma dama. 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. Kula da samfuran samfuran da ke amfani da kayan aikin Alliy da filayen injiniya, wanda ingancinsa da sabis na sabis ne in mun gwada da talakawa.
⑥ Water saving
The faucet with a bubbler saves water better. Feel the water flow with your hand when purchasing. Da mai laushi ruwa ya kwarara da bera (Abun Ruwa Mai Ruwa) indicate that the bubbler is of better quality.
