When choosing a kitchen faucet, I often consider the question: can it last for a long time? Will it poll the water quality? To address these issues, it is necessary to first understand the structure of the faucet

The overall structure of the faucet is divided into valve core, main body, and surface layer The valve core is the part that controls the inlet and outlet of water, and is the heart of the faucet Which it can be durable or not dependent on this; The main component of the faucet is the skeleton, and most of the water pollution is due to poor raw materials; The coating is the surface material of the faucet, which is the skin of the faucet, and it serves as the appearance of the faucet

Can it last long?

The faucet is turned on and off every day, and we cannot remember how many times it has been turned on and off in a day Therebefore, the first question we consider when purchasing is where it can be used for a long time When the faucet is turned on or off, the active part of the faucet is located on the valve core, so if you want it to last longer, it depends on the quality of The valve core

The quality of the valve core can be adjusted by which it can stand a long last drive free test, which is a lifespan test for the valve core There are clear regulations in the national faucet testing standards that require a no drive test of no less than 200000 switching times for switches In addition to adjusting quality from this test indicator, Sensor evaluation can also be conducted Turning the handle up, down, left, and right, with a simple and unobstructed feed, demonstrating outstanding quality

2. To see if the faucet will poll the water quality, it depends on the raw materials of the main part that has been touched by the tap water for a long time

The main raw materials for the faucet body include cast iron, plastic, zinc alloy, copper alloy, and stainless steel

Cast iron is prone to rusting, plastic is prone to aging, zinc alloy has poor stability, and is prone to cracking, resulting in poor durability Thereforee, it is not recommended to purchase faucets made of these three raw materials

Nowadays, copper alloy is the most suitable main material for home use due to the bacterial effect of copper ions and the inability of bacteria to produce antibiotics, the inner wall of copper faucets will not break bacteria, which is comparable to other materials This is also why many brands choose copper materials to make faucets

Brass in copper alloys is a combination of copper and zinc It mechanical properties, wear resistance, and corrosion resistance make it the preferred material for faucets Brass can be classified into variant types due to its high copper content Nowadays, most troubles are made of H59 copper, which accounts for 57% to 61% of the copper content In fact, Some global bathroom brands even use H62 copper to product faucets Compared to H59 copper, H62 copper has a higher copper content and better corrosion resistance

In addition to copper and zinc, brass also contains trace amounts (less than 0.5%) of lead When a faucet is exposed and causes lead poisoning, we assume it is caused by the lead in the brass itself How, all those who talk about running when leaving the message are playing hooligans Currently, The national standard setting for the lead content in failures is that only the amount of lead released should not exceed 5 μ G/L, it will not cause human health In fact, the standardized H59 copper does not need to worry about this issue Most of the faucets on the market that has detected exceptional lead precision are not standard bras, but are made of zinc alloy that is standard, or contain too many inputs, or are processed rough from recycled copper These faucets have quality issues s
