12 Years Professional Faucet Manufacturer

Cutting corners caused frequent sampling inspections of taps, the new national standard still needs to be implemented

Faucets are commonly known as faucets. With the continuous improvement of people’s living standards, the functions and appearance of faucet products are far different from before, but in terms of quality, there is still not much improvement. Since December 1, 2014, more attention has been paid to environmental protection and safety than the original national standard, and the total metal precipitation, sealing performance, flow rate and life of the faucet are mandatory terms since the “ceramic sheet sealed faucet” (GB18145-2014) was officially implemented , Unqualified sampling still occurs frequently, and product quality issues are worrying.

Sampling inspection of taps repeatedly exposed problems

Since the beginning of this year, relevant departments in various regions have successively released the sampling inspections of tap quality.

On June 10, the Beijing Municipal Administration for Industry and Commerce released the results of a random inspection of faucets in the circulation area of ​​the city. After sampling inspection, it was found that 26 groups of faucets were unqualified. The unqualified items were surface corrosion resistance, faucet water efficiency limit value, faucet water saving evaluation value, flow rate, etc.

In June, the Wuhan Municipal Bureau of Industry and Commerce in Hubei Province issued a monitoring report on the quality of faucets in the city’s circulation field for the ** quarter of this year. The results of sampling showed that 5 batches were unqualified, and the unqualified items mainly included metal pollution precipitates and pipe thread accuracy.

In July of this year, the Zhejiang Provincial Bureau of Quality and Technical Supervision announced the results of the province’s faucet product supervision and random inspection. Among the 19 batches of faucet products, 4 batches were unqualified, and the batch failure rate was 21.1%. Among them, 1 batch of basin taps produced by Zhejiang Gaolang Sanitary Ware Co., Ltd. and 1 batch of basin faucets produced by Pujiang Lemen Sanitary Ware Co., Ltd. were judged to be unqualified for “pipe thread accuracy and material hygiene requirements”. Yuyao Zhili Sanitary Ware Factory A batch of washing machine faucets produced was judged to be unqualified in pipe thread accuracy, and a batch of washing machine faucets produced by Zhejiang Ruige Copper Co., Ltd. was judged to be unqualified in pipe thread accuracy and flow.

On August 3, the Bureau of Industry and Commerce of Hebei Province announced to the public the quality monitoring of faucet products in the circulation area of ​​the province. 4 batches of substandard faucet products were exposed, of which 3 batches of nominal brands were submarines, and substandard products existed The main quality problem is that the thread accuracy is not up to standard.

On October 10, the Fujian Provincial Quality Supervision Bureau released the results of a random inspection of the quality of faucet products in the second quarter of this year. The bureau randomly inspected 100 batches of ceramic sheet sealed faucets produced by 78 sanitary ware companies. A total of 48 batches of ceramic sheet sealed faucets from 44 companies did not meet the standards. The main non-compliant items were pipe thread accuracy and surface corrosion resistance. .

On October 21, the Shaanxi Provincial Bureau of Quality and Technical Supervision announced the results of the random inspection of the ceramic sheet sealing faucet market in the third quarter of this year. A total of 40 batches of samples were selected and 15 batches were unqualified. Unqualified products involve brands such as Shenluda and Zhongyu, and unqualified items involve pipe thread accuracy, surface corrosion resistance, flow, etc.

The above sampling results show that the unqualified items of tap products mainly involve pipe thread accuracy, surface corrosion resistance, heavy metal precipitation, flow rate, etc.

Cutting corners is the main reason

According to experts, unqualified pipe thread accuracy is mainly manifested in that the pitch diameter of the thread is greater than or less than the specified value, and water drips, runs, and leaks between the water nozzle and the water supply pipe may damage the interests of consumers. The main reason for the disqualification is that the coating process and quality on the surface of the faucet are not good enough.

The faucet that fails the surface corrosion resistance test will have “patina”, black spots or corrosion on the surface after being used for a period of time, which will affect the appearance, and even the use in severe cases. The main reason for the non-conformity is that the electroplating process of the manufacturer is defective.

The flow of the faucet determines whether the faucet saves water and satisfies the normal use function: a large flow will waste water resources; a small flow will affect normal use. The unqualified reason for the low flow rate is that the product structure design is unreasonable and the valve core water outlet design is too small.

Experts from Xianyang Ceramic Research and Design Institute analyzed that an important reason for the above-mentioned quality problems in some products is “cutting corners”.

The new national standard faucet stipulates that the part of the faucet that directly contacts the water should not use zinc alloy materials. However, there is still a phenomenon of using zinc alloy faucets to pretend to be copper alloy faucets in the market.

In addition, some small companies have difficulty guaranteeing quality in the electroplating process. Some large brand companies generally have dedicated electroplating plants whose electroplating process can meet the national mandatory requirements such as the corrosion resistance of the tap surface.

Put the new national standard in place

Xi’an Daming Palace Building Materials Market is the largest wholesale distribution center for hardware plumbing in Northwest my country. The author recently visited the market and found that many merchants are selling some low-priced taps of tens of dollars or more. Some operators told me that compared with branded faucet products that cost hundreds or even thousands of dollars, cheap faucet products are relatively inferior in quality, but the price is relatively cheap, and many people buy them.

The person in charge of the Xi’an direct sales center of a sanitary ware factory in Fujian told the author that, generally speaking, the quality of base material and surface electroplating process of faucets produced by well-known brand manufacturers are much higher than that of small manufacturers, and the production cost is higher, so the price is also It’s much higher. “Generally, the faucet with a value of several tens of dollars must be made of tin alloy base material, and the electroplating process is poor, and it will rust and leak water after a short period of time.”

An expert from the National Building and Sanitary Ceramics Quality Supervision and Inspection Center said that the new national standard has been implemented for nearly a year. It seems that there are still many faucet products on the market that do not meet the standard requirements. This shows that many manufacturers still do The poor performance also reflects that many consumers do not understand the relevant standards. “It is hoped that the relevant departments will further increase the enforcement of random inspections, promote the survival of the fittest in the faucet industry, and improve the quality of faucet products in an all-round way. At the same time, it is also hoped that relevant parties will increase their efforts to publicize the national standard of faucets and popularize the correct purchase of faucets to consumers. And use knowledge to reduce the market space for low-quality taps.”
