How to buy faucets?

The faucet , although a small object, has an extraordinary role. Since the invention of the faucet in Washington in 1937, the development of the faucet has gone through a rapid and long period of time. It has witnessed the traditional virtues of water culture and water conservation in China since ancient times.

Faucet Selection Guide Point 1: Faucet Handle

At present, the control handles of the faucet are mainly divided into spiral type, single handle, double handle, and 90° switch type.

The faucet control handle has a single handle and a double handle. The single handle is characterized by convenient control and simple structure. The double handle requires two hands to adjust the water temperature, but the style can be suitable for more occasions (such as under the basin faucet, the cylinder faucet of the massage cylinder, etc.), and the double handle faucet adjusts the water temperature. More smooth and delicate than a single handle, suitable for consumers who are sensitive to temperature. When the single-handle faucet is turned on and off, the water pressure will rise rapidly. If the copper content of the product is not high, it will not be able to withstand the expansion of the water pressure, so the single-handle faucet should be slowly opened and used. shut down. The double-handle faucet has a large pressure range, and the water pressure is slowly released, so there is no such problem. However, the double-handle faucet cannot be closed too much, otherwise the water stop plug will fall off, causing the water to stop and stop.

90 ° with a switch, in the traditional double handle based on the change of the original rubber seal sealing ceramic tiles, spin transfer to the handle 90, the hot and cold sides minutes when water is adjusted to open and close, which is characterized by open Convenient and more styles.

The traditional spiral-stabilized rubber-sealed faucet is still popular with some consumers due to its large water output, low price and easy maintenance.

Faucet Selection Guide Point 2: Faucet Bubbler

Not all faucets have bubblers, but generally better faucets will have this structure. The main function of the bubbler is to prevent the water from spreading, so that the water flow is relatively straight, and the intuitive feeling is that the small bubbles are hit on the hand, and there is no splashing everywhere. In addition, it has a certain water saving function.

The bubbler of many brand products has a certain filtering effect, which can filter the particulate impurities in the tap water. If the water quality in the area is not good, the tap water will gradually decrease, and the bubbler can be turned on to restore the normal after washing. A good bubbler is made of high quality stainless steel mesh and can be seen.

When purchasing, it is best to choose a faucet with a bubbler. The water flow is soft and foaming (the bubble content of the water flow) is rich, indicating that the bubbler is of good quality. The bubbler generally consists of six layers, usually consisting of a metal mesh cover (partially plastic). When the water flows through the mesh cover, it is cut into a large number of small water columns with air in between, so that the water does not splash around.

Faucet Selection Guide Point 3: Faucet Spool

The spool is a valve part that performs the basic functions of direction control, pressure control or flow control by means of its movement. The control of any faucet requires a spool. For the faucet, the quality of the spool is an important basis for the quality assessment of the faucet. It can be said that the most important factor affecting the quality of the faucet is the spool.

There are three common spool: ceramic valve core, stainless steel roll-ball valve body and the shaft.

Ceramic valve cores are widely used because of their affordable price, low water pollution, good wear resistance, good sealing performance, and improved "brittleness". In general, the ceramic valve core plays a very good sealing role. Due to the relatively strong foreign technical strength, some imported ceramic chips have relatively good sealing performance, stable physical properties, wear resistance and long service life. Most of the mainstream faucets produced by most well-known brand sanitary ware manufacturers on the market have already adopted ceramic valve cores.

The advantage of the shaft rolling valve core is that the handle is smooth and smooth, the operation is easy and simple, the hand feels comfortable and easy, and it is resistant to aging and wear. However, as an old-fashioned spool, the shaft-rolling spool has gradually failed to meet the demand of the current population for the spool, so it will gradually be eliminated by the market. The shaft rolling spool is now rare in the leading brands of large brands.

Faucet Selection Guide Point 4: Faucet Plating

Electroplating is an important indicator reflecting the inner quality of the faucet and the strength of the manufacturer. It not only makes the appearance of the faucet more beautiful, but also functions to protect the faucet, anti-corrosion and rust prevention. The valve body, handle and bonnet of the excellent faucet are usually electroplated with nickel, decorative chrome or chrome after casting, processing, surface grinding and polishing. . Some faucet surfaces are coated with titanium, bronze (imitation gold), gold-like electrophoretic paint. Electroplating electrophoretic paint or bronzed faucet surface corrosion is often very fast, and these three users are generally difficult to identify. In addition, the thickness of the plating is also very particular, if it is too thin, it is easily oxidized and etched. Currently, the international standard for faucet plating thickness is 8 microns, preferably up to 12 microns. Nickel alloy

Excellent faucet products are generally plated with semi-gloss nickel, bright nickel and chrome on the copper body. In general, the first layer of copper plating enhances the adhesion of the plating, and the nickel layer (including semi-gloss nickel and bright nickel) acts as a corrosion resistance. Since nickel itself is soft in material and dark in color, a layer of chrome is plated on the nickel layer to harden the surface while increasing brightness.

Many domestic products that claim to have five layers of electroplating have “three-layer electroplating”, which generally includes three layers of copper such as hydrogen plating copper, pure copper and acid copper, and then nickel plating and chrome plating. The same copper substrate, the material is also very different; many copper materials contain a lot of impurities, often polished out there will be a lot of pits. At this time, it is necessary to plate the copper layer again on the copper substrate. Due to the good ductility and good fluidity of the copper element, the copper plating process is as if we use the putty to smooth the wall surface, fill the outer layer of the body to the electroplatable standard, and then plate nickel and chrome.

“Five-layer plating” is actually caused by defects in the copper substrate and manufacturing process. Moreover, the expansion coefficients of metals of different materials are different, and the taps use cold water hot water every day. Under such high-frequency hot and cold cycles, the delamination coating layer and the layer are easily changed due to different expansion coefficients. There are quality problems such as peeling off and wrinkles, so the plating is really not.

Faucet Selection Guide Point 5: The function of the faucet

From the use of the faucet, there are the following categories:

1. Basin faucet:

It is mounted on a wash basin for cold water, hot water or mixed hot and cold water. The main body is made of brass , and the exterior is chrome-plated, gold-plated and various metal baking varnishes. The shapes are various, and the handles are single-handle and double-handle. There is also a basin faucet equipped with a falling water lifting rod, which can be directly pulled to open the water outlet of the wash basin to remove sewage. This faucet is used in conjunction with the bathroom vanity to wash and wash your face. Therefore, it is practical and coordinated to choose a faucet with a short nozzle and a low nozzle , but it is necessary to leave enough washing space. After locking such a faucet, first look at whether the faucet mounting hole of the basin is single or triple, and then select the faucet according to the actual situation.

2. Kitchen faucet:

If your kitchen has hot water pipe line, this should also be leading a double. Exceptionally, the kitchen faucet has a higher, longer outlet and some hose designs for your food. The faucet should also be very long, preferably extending above the drain and not splashing.

3. Bathtub faucet:

It is placed on the side of the bathtub for open hot and cold water. At present, there are many ceramic valve core single-handle bathtub faucets on the market . It uses a single handle to adjust the water temperature and is easy to use. The ceramic valve core makes the faucet more durable and watertight. The body of the bathtub faucet is made of brass, and the exterior is chrome-plated, gold-plated and various metal baking varnishes. This faucet must have two outlets, the bottom for filling the bathtub and the other for connecting the shower . After recognizing, it is also necessary to note that the length of the faucet spout is slightly longer than the width of the edge of the bathtub, so as to ensure that the water does not flow outside when the water is injected.

Faucet Selection Guide Point 6: Faucet Material

With the development of modern faucets, with the development of economy and science, various faucets with cast iron, all-plastic, all-copper, alloy, ceramic, stainless steel and other materials have emerged. Among them, cast iron faucets have been gradually eliminated, and all plastic faucets are mostly used in special fields. Nowadays, the most commonly used faucets in households are mainly copper, alloy, ceramic and stainless steel faucets. Alloy faucets have become more and more out of sight because of their health hazards. Although ceramic and stainless steel faucets have their own advantages, they are generally expensive and difficult to process, so the types and quantities of products are small. All copper faucets occupy the dominant position in the leading materials market with its excellent cost performance.

First, the whole copper faucet

The pure copper faucet is made of all-copper, chrome-plated, high gloss and high anti-wear and anti-corrosion properties. Mainly based on its own copper content and process to distinguish the quality of the pros and cons. The copper used in the plumbing industry is mainly 59 copper. In addition to copper, there are other metal contents. If the lead content is too high, it will be detrimental to human health. The lead content of many faucets on the market is generally between 3% and 5%. In response to this situation, some manufacturers have developed low-lead faucets with lead content of less than 0.3%. In view of the fact that the lead content is generally difficult for consumers to judge, and internationally, there is strict regulation on the lead content of pipeline products, so it is best to purchase the faucet that has passed the relevant certification for your own health considerations. (Small TIP: When you wake up every morning, you can turn on the faucet for half a minute, and let the water in the head be drained to avoid excessive lead.)

Second, the alloy faucet

The price of the alloy faucet is much lower than that of the all-copper faucet, and the faucet is easier to produce on a large scale. Which is used in large quantities is The zinc alloy faucet is harmful to the human body and is not durable. At present, zinc alloy can be used as a handle for faucets and some bathroom hardware accessories . Since the zinc alloy plating process is very mature, and some manufacturers will deliberately increase the weight of the zinc alloy faucet, it is difficult to distinguish it from the full copper faucet by weight and appearance. For your health, it is still recommended to buy a leader who has passed the relevant certification and evaluation agency evaluation. Zinc alloy

Third, ceramic faucet

Ceramic faucets, as the name implies, are the leading ceramics. Compared with other faucets, ceramic faucets have the advantages of no rust, no oxidation and no wear. The ceramic faucet looks beautiful and elegant. Because the outer casing is also a ceramic product, it can be matched with the bathroom products, adding the artistic sense of the ceramics and setting off the high-grade temperament of the bathroom.

Fourth, stainless steel faucet

Quality stainless steel faucet does not contain lead and acid, alkali, from corrosion, does not release harmful substances, does not pollute water sources. It is understood that the surface of the stainless steel faucet above 304 does not need electroplating. Its surface only needs polishing to show its stainless steel color, and it can maintain the silver-white luster and never rust. The hardness and toughness of stainless steel are higher than that of copper. More than 2 times. However, stainless steel is much more difficult and costly than copper in terms of hardness, toughness, solution casting and cutting.
