VIGA усны цорго үйлдвэрлэгч 
Саяхан, the Nanjing Municipal Quality Supervision Bureau released the results of the 2017 random inspection of the quality of household furnishings, усны цорго оролцдог, зэвэрдэггүй ган угаалтуур, bathroom brackets and paint-free plates. The passing rate of faucets is the lowest at 67.5%, of which the passing rate of faucets priced at RMB 100 and below is only 14.3%.
Доорх Тапкатын тэгш бус хувь 100 юань шиг өндөр 85.7%
Prior to this, the Nanjing Municipal Quality and Technical Supervision Bureau entrusted the Nanjing Product Quality Supervision and Inspection Institute to conduct a random inspection of 40 batches of spout products sold in Nanjing’s production enterprises, circulation areas and e-commerce platforms. Хяналтын дараа, 27 batches passed and 13 batches failed, дамжуулалтын хурдтай 67.5%.
Nanjing Quality Supervision Bureau has classified the test results based on the product source and price range, and the results are eye-catching.
Тухайлах ялгац гишүүн 40 batches of faucet products in this random inspection were sampled from physical stores, Цахим худалдааны платформ ба үйлдвэрлэлийн компаниуд, respectively for 20 багц, 19 багц ба 1 batch. Тэдний дунд, the physical store product qualification rate is the lowest, 55%; the e-commerce platform product qualification rate is 78.9%; the production enterprise product qualification rate is 100%.
Бүтээгдэхүүний үнийг хэтийн төлөвөөс, дамжуулалтын хувь хэмжээ 400 yuan and above is 100% (failure rate 0%), the pass rate of products between 200 yuan and 400 yuan is 85.7% (failure rate 14.3%), 100 yuan to The pass rate of products between 200 yuan is 62.5% (unqualified rate is 37.5%), ба дамжуулалтын хувь хэмжээ 100 юань ба доор 14.3% (unqualified rate is 85.7%).
2 batches of metal contaminants in the water nozzle have exceeded the standard
This sampling inspection was conducted in accordance with GB 18145-2014 “Ceramic Sheet Sealed Water Nozzle” ба gb 25501-2010 “Liquid Water Use Efficiency Limit Value and Water Use Efficiency Grade”. Дунд 13 Төгжөөгүй бүтээгдэхүүний багц, the unqualified items mainly involve surface corrosion resistance, усны үрлэнхэн зэрэг, урсгалын жигд байдал, материал. Тэдний дунд, the detection of metal contaminants (хар тугалга) in two batches of products exceeded the standard.
Үүнээс гадна, the sampling inspection also referred to the QB / Т 1334-2013 “General Specifications for Water Spouts” Стандарт, and the sealing performance of the spouts was frozen at -10 ℃ for 4 цаг, 8 цаг, 12 цаг, болон 24 hours Risk monitoring. Хяналтын дараа, 33 batches of water nozzles meet the standard requirements, and the compliance rate is 82.5%.
Хяналтын зүйлийн дүн шинжилгээ
① Flow uniformity and water efficiency grade
Flow uniformity and water efficiency grade In the sample of this random inspection, one batch of water efficiency grade failed, the project pass rate was 97.5%; three batches of flow uniformity failed, the project pass rate was 92.5%. These two items are requirements for the energy efficiency of the water nozzle, and the uniformity of the flow rate is the prerequisite for evaluating the water efficiency level of the nozzle. Excessive flow rate of water nozzles will cause waste of water resources, which is not conducive to the implementation of China’s energy conservation and emission reduction policies.
· Active ArtoSion эсэргүүцэл
Among the samples of this random inspection, 12 batches of surface corrosion resistance failed, энэ төслийн дамжуулалт байсан 70%. Products with unsatisfactory corrosion resistance on the surface are prone to rust during use and do not provide protection, affecting the aesthetics and use of the product. The corrosion resistance of the surface of the water nozzle not only depends on the electroplating process of the enterprise, гэхдээ материал гэх мэт янз бүрийн асуудлыг хамардаг, цутгах үйл явц, өнгөлөх, урьдчилан сэргийлэх.
③ Precipitation of metal contaminants
In the sample of this sampling, 2 batches of metal contaminants were deposited unqualified. The qualified rate of this project was 95%. Металл бохирдуулагч бодисын хур тунадас нь хүний эрүүл мэндтэй холбоотой байдаг, ялангуяа хүний биед хар тугалганы хуримтлал, which can cause long-term health risks and affect the normal physiological functions of the human body. The copper grade of the spout product is low, and the production process of the enterprise does not meet the standard, which is the cause of the excessive precipitation of metal contaminants.

④ АЖИЛЛАГАА
Among the samples of this random inspection, 7 batches of materials failed, and the pass rate of the project was 82.5%. Зарим бүтээгдэхүүн нь цайрын хайлш ашигладаг, which is a corrosive material that is only 1/3 of the copper alloy. Энэ материалыг корицле хийхэд хялбар байдаг, энэ нь зөвхөн гадаад төрх байдалд нөлөөлдөггүй, but also reduces the strength of the nozzle, and leaks and cracks after a period of use. Зэс хайлштай харьцуулахад, zinc alloys are low in price and easy to form. Some companies use zinc alloys to replace copper alloys in order to control costs and reduce processing links, in order to obtain greater profits.
⑤Risk items (нарийн байдлын шалгалт)
This spot test carried out a temperature test, тэр бол, the sealing performance was tested after freezing the water nozzle at -10 ℃ for 4 цаг, 8 цаг, 12 цаг, болон 24 цаг. Туршилтын дараа, дунд 40 batches of taps in this random inspection, нийт 7 batches showed leakage under low temperature environment.
Одоогоор, there is no corresponding national standard for the temperature resistance value of the faucet. Ердийн нөхцөлд, the water nozzle will not be frozen and cracked at a few degrees below zero, but after freezing at low temperature, the water in the spool expands and condenses into ice, which will cause squeezing force on the spool. Холболт дээр гоожсон байх болно. Зардлыг хэмнэхийн тулд, some production enterprises use poor quality brass as the casting material of the faucet. The metal ductility is greatly reduced, and it is easy to freeze and break at a low temperature.

① Avoid buying zinc alloy faucets
Zinc alloys are highly corrosive materials, and such products should be avoided first when purchasing faucets. Энэ нь бүтээгдэхүүний дотоод хөндийд ялгах боломжтой. The copper material is generally a casting. The flatness of the inner wall of the product is not very good. The zinc alloy is obtained by injection grinding. The inner wall will be very smooth and the inner wall will have obvious separation lines. Under conditional conditions, the color of the zinc alloy may be white, while the copper alloy may be yellow.
② Avoid buying low-cost faucets
The unqualified rate of faucets under 100 юань шиг өндөр 85.7%, and it involves more materials, metal contaminants and other items that have a greater impact on consumer health, so it is not recommended to buy.
③ Look at the surface
Visually inspect whether the electroplated surface of the spout is uniformly lustrous, and pay attention to whether there are defects such as peeling, дуун арчих, scorching, exposed bottom, гэж их хүндэг, black spots and obvious pitting. The surface structure of the sprayed surface should be fine, smooth and uniform without defects such as sagging and exposed bottom. No burr and grit feeling on the hand.
④ Look at the thread
The pipe thread of the water nozzle is connected with the connecting hose or pipe. Худалдан авахдаа, visually inspect the thread surface for dents, broken teeth and other defects, especially pay attention to the effective length of the pipe thread.
⑤ Мэдрэмжийг хараарай
You can try turning the handle up, доош, зүүн, ба одоогийн. If it feels light and there is no blockage, it means that the valve core is better. The main parts of a good quality spout are made of brass. Хайлтын материал, инженерийн хуванцарыг ашиглахын тулд анхаарлаа хандуулаарай, Хэний чанар, үйлчилгээний амьдрал харьцангуй ядуу байна.
⑥Water saving
The faucet with a bubbler is better for saving water. Хэзээ худалдаж авах, you can feel the flow of water by touching it with your hands. Зөөлөн усны урсгал ба баялаг хөөс (усны урсгалын хөөс агууламж) indicate that the bubbler is of good quality.
