Material: copper is a different reminder: copper content is not the same quality
Recently, this reporter went to a hardware market, many businesses in sales taps and showers will introduce their own advantages products to consumers, which on this material, copper is absolutely the main star. Currently on the market faucet with copper alloy, according to businesses. This is mainly because copper casting metal flow better, also with respect to the steel is not easy to be oxidized. Many businesses in the introduction of material is often will make up a no lead, some businesses will emphasize the amount of copper, in the course of a reporter asked, a business told reporters that the amount of copper taps the more the better quality. So the quality of the faucet is really related to the number of copper?
The reporter interviewed a researcher at the Beijing city building hardware plumbing products quality supervision and inspection station of the laboratory, the researcher told reporters, currently on the market are basically faucet made of copper alloy, and other materials, such as stainless steel market share is very low, is made of copper alloy as tap material, mainly because of copper has natural antibacterial activity, compared to other materials more suitable for the production of copper alloy and making the tap tap, for having different grades, different grades of copper and copper alloy containing different amount of copper alloy, whether it is what kind of grades they meet national standards this brand is regarded as a qualified product, and the amount of copper the level of business only shows that production costs low, and can not explain the quality.
"The most common parts is the hardware market in the shower". The shower materials have "copper was strange". The reporter asked several special hardware sales business after the answer is material is copper. According to experts, at present market of our country on the shower material is mainly plastic, some of the imported product is made of pure copper, differences between the two is mainly in the production process, cost is different, but in terms of quality and no, also need to pay attention to is, in our country currently locked in metal pollutant emission standards only for washing machine and kitchen faucet set, and like a shower has not introduced mandatory metal pollutant emission standards.
Process: heavy metal pollution is inevitable reminder: put water can be solved
ccording to the currently on the market copper alloy tap, stainless steel faucet of heavy metal exceed the standard problem, researchers told reporters that both material or process may lead to excessive heavy metals, in the process, mainly electroplating heavy metal exceed the standard, but the heavy metals exceeded the Lord to a source or material itself, by adding a small amount of lead can improve the cutting property of the brass, so copper alloy tap prone to excessive lead, and stainless steel faucet often do not lead, but it may cadmium and other heavy metal exceed the standard problem, it is recommended that consumers who purchase tap first select the formal channels to purchase certified faucet. But lead is not completely free of lead, but the precipitation of lead in line with the national standard that is not more than 5 micrograms / liter. If tap for a period of time, you should first drain, originally stored in tap water releasing to ensure quality and safety.
According to China's current of the ceramic sealing tap "GB18145-2014 GB is applicable to the washing machine and kitchen faucet metal pollutant emission standards are clearly defined, including lead, 17 kinds of metal in the new GB were given mandatory standards, in particular the needs for, because the faucet process tends to have electroplating, but also relates to copper of secondary processing, so in this series in the process will produce metal pollution, given by the new national standard of metal pollutant emission standard is for finished water.
Spool: the core of the core of the most critical reminder: select a comfortable sense of damping
Faucet price from tens of dollars to thousands of dollars, and in the end is what causes such a huge price gap? High price means high quality? Researchers told reporters, the reason water prices will have such a big difference, is mainly in the spool. Currently on the market more than the faucet spool for the ceramic, all will be more ceramic spool, on the one hand because the ceramic has a good wear resistance, on the other hand, the cost of ceramics is low.
Reporters found that the same as the ceramic spool, the use of ceramics are not the same. Researchers explain, ceramic is indeed different, such as different hardness, wear-resisting degree is also different, but for the spool, the most important material is not, but the overall valve in structure, technology gap, good valve not only high hardness, wear-resisting degree of strong, long service life, the valve core of the regulating performance is better, in the use of process regulation accuracy better, also good spool in high-pressure situations can still effectively prevent water leakage, but also reduce the water flow impact brought about by the noise. The quality of the water faucet is basically no problem. In addition to material differences, the most important is the structure, process, design differences.
Detect valve tips, consumers can in turning the faucet handle feel the product whether there is a sense of damping and good spool tend to have a comfortable damping sense, and damping of some sense of small faucet is not recommended to buy. But a lot of consumers say that this damping is a little bit like a fog. If there is no professional testing, how can you get this kind of professional damping feeling?
Choose a quick way to pick the tap
So consumers in the actual purchase of the taps should be how to pick it? The industry told reporters that the first look at the look of the first look at the appearance, the overall appearance of the current
The ceramic sealing tap "(GB 18145-2014) GB plating surface gloss of uniform, there should be no peeling, cracking, burning, grinning, peeling, dark spots and obvious pitting, burrs and other defects; surface coating is very fine, smooth, uniform color, there should be no sagging, grinning and obvious scratches and bump etc. defects; polished surface should be smooth, should clear burrs, scratches and bump and imperfection.
Next: Sorry, no information!
