Modern people take health very seriously, every home is equipped with a filtration device, but I don’t know, buy a poor-quality faucet, your expensive filtration device is also for nothing. Faucet secondary water pollution, it’s scary to think about. So, how much is a reliable tap? It’s expensive, it hurts, it’s cheap, it’s uncomfortable, it’s afraid of the quality.
To summarize the next two points.
1、Water faucet, how much is suitable?
2, 0 lead copper taps really exist?
Full copper faucet, exactly how much is appropriate?
The bad of a tap is not judged by its appearance (for a short time it is impossible to tell how good the surface coating is), it is basically present in the body material and the spool.
1、The weight of the main material.
To seize the market, to fight the price war, the same copper, all have to pass the national standard certification, then the quality of the material does not drop on the basis of the amount of I must find a way to reduce ah, so the above saw the poor reviews came out: thin, light.
A penny for a penny, the old adage goes a long way.
So it’s easy to weigh in when you can’t practice your eyesight.
Spool relative to the heart of the faucet, control is the lifeblood, a faucet is good, not for long, the key is still in the spool.
The faucet leaks, in addition to the handle is not closed tight or loose, resulting in a failure to close the faucet in place, it is more likely that you bought a faucet with a poor quality spool. There is a problem with the spool, which cannot be repaired, only replaced. Changing the wick is a technical job that the average family doesn’t do, so 1, continue to put up with leaks and drips, and 2, change the tap.
In the industry, there are also many materials and styles of valve spools, which can be seen in the market, such as ceramic spools, stainless steel spools, roller spools. The most widely used and most cost-effective is the ceramic spool.
Mainstream valve spool in the market, little water pollution, wear resistance and aging, good sealing performance.
Stainless steel valve spool
High price, not easily affected by impurities in the water life, and at the same time on the rotation aspect of a greater adjustable angle, the water quality is not good in the area to choose this more practical.
The old spools, which have been phased out, are no match for the first 2, both in price and life.
After telling the low cost full copper faucet routine, does life feel like a pit everywhere?
The premise of the foregoing is that the use of good copper, thinner and lighter, tolerate the past, but if you encounter a poor quality copper, I urge you to quickly change, the minute you drink a mouthful of poison.
Do 0 lead copper taps really exist?
In 2018, the state introduced the most stringent faucet inspection standards in history, which set off a wave in the faucet industry to see the “lead” color change. In order to make their faucets sell well, some businesses advocate that their faucets are made of pure copper.
Those who have read the book know what pure copper is, pure copper is copper that has been technically refined and is more than 99.5% pure, pure copper is a soft metal, not easy to cut, may I ask that businessman will make a tap with pure copper?
Pure” copper is copper that does not exist in nature and is mostly found as a compound, the copper mineral.
Pure copper: the highest copper content, the content of 99.7 to 99.95%; also known as purple copper, the main components of copper and silver, the main impurity elements: phosphorus, bismuth, antimony, arsenic, iron, nickel, lead, tin, sulfur, zinc, oxygen, etc.; used in the manufacture of conductive equipment, advanced copper alloy, copper-based alloy. Red copper with more than 96% copper content is generally referred to in the market as pure copper, or purple copper. Pure copper is expensive, tough and ductile, in contrast to its strength, low hardness, soft and unsuitable for machining. Copper alloys change the properties of copper, making it more widely used.
Copper alloys change the properties of copper, making it more widely used. There are three common types of copper alloys.
1、Common brass: It is an alloy made of copper and zinc.
2、Brass: A polyalloy formed by adding other alloy elements to ordinary brass. The elements often added are lead, tin, aluminum, etc., mainly to improve the tensile strength to improve the process, can be called lead brass, tin brass, aluminum brass.
3, complex brass: improve the brass corrosion resistance, strength, hardness and cutting, etc., in the copper-zinc alloy to add a small amount (generally 1% to 2%) of tin, aluminum, manganese, iron, silicon, nickel, lead and other elements.
So, to understand that all full copper faucets with copper alloy, there is no 0 lead copper faucet, net lead, low lead, lead-free only represents the content of lead, the real important is the amount of lead precipitation, it is related to our drinking water safety.
Brass contains lead and we’re all drinking poison?
Don’t worry, for the production of faucets, the state has quality control standards, as long as the control is within the scope, water safety is still possible. 2018 implementation of the faucet testing standards, the industry said the most stringent faucet standards in history, the requirements for the spout heavy metal precipitation has new requirements. 16 heavy metal elements, including lead, and 17 efflux value indicators are specified as mandatory provisions. Among them, the statistical value (Q) of lead precipitation was not greater than 5 μg/L.
Is copper toxic or not?
In a certain sense, any substance is toxic to the body as long as it reaches a certain amount, but if it is below a certain amount, no substance is toxic, the key is the amount of contact with the body, the means of contact, the mode of contact and the physical and chemical properties of the substance itself, but in most cases the amount of contact with the body is the determining factor.
The potential toxicity of copper to the human body is very low, and it is only when the intake greatly exceeds the normal value that adverse reactions such as gastrointestinal disturbances can be caused. With the advancement of science and technology, it has been discovered that other elements in copper alloys have an existentially harmful effect on the health of the body: the premise and the basis is – over-absorption.
