There are many facets on the market today, such as all-plastic polyvinyl chloride (PVC), ceramic, stainless steel, and copper (or brass). In addition to the simple process of PVC faucet, the other three materials are more common faucet.
Although the faucet containing copper or copper is slightly higher in price, but because of its antibacterial properties and stability, it is more popular in the market.
2. Valve core
The valve core is an important part that determines the experience of using the faucet. The better faucets on the market are generally ceramic valve core, high temperature, wear resistance, can be suitable for a variety of family water environment. Moreover, the ceramic valve core has good sealing performance, more comfortable and smooth opening and closing feel, and long service life.
In addition to the ceramic spool, there are steel ball spool and stainless steel, rubber material spool.
The faucet will be finished in the surface process. Copper faucets are generally polished, stainless steel faucets are generally polished and brushed.
First, the faucet purchase reference standard – check the appearance.
In order to avoid the faucet in the manufacturing process by oxidation, faucet in the polishing will be in the appearance of a layer of nickel or chromium plated, so that the faucet can be long-term corrosion. A fine faucet must be smooth as a mirror, delicate and delicate, so observe it in a well-lit location when you buy it. Faucets have no oxidation spots, no pores, no missed plating, and no scorch marks. The color is even, no burrs and sand particles. It is a good product.
Second, the faucet purchase reference standard – the internal structure.
The valve core is the heart of the faucet. Ceramic valve core is the best valve core. The valve spool is made of high resistance ceramic. Even if the pressure is 60psi, it can switch freely and will not leak. It feels more comfortable and smooth and opens and closes quickly. Our common faucet valve cartridges are steel ball cartridges and ceramic cartridges. The steel ball spool has good pressure resistance, but the disadvantage is that the rubber ring that acts as a seal is easily worn and will deteriorate quickly. In the purchase, you can easily judge the quality of the valve core by turning the handle.
Third, the faucet purchase reference standard – material.
The material of the faucet to copper is better. This material itself has a good sterilization effect, followed by stainless steel. Do not choose zinc alloy. Because zinc alloy is not corrosion-resistant, easy to precipitate heavy metals, hazardous to human health. The material of the inside surface of the faucet can be judged by the color of the inside surface of the faucet to judge. The color of the inner surface of the zinc alloy faucet is dark yellow, and the color of the inner surface of the copper faucet is yellow.
When selecting the faucet, pay attention to whether the surface has burrs, pores, corrosion, oxidation spots, etc. Whether the surface is clean as a mirror is a basic standard for judging the quality of the faucet. Under a simple test, blowing breath on the surface of the faucet, water vapor dissipates quickly, indicating a better surface treatment.
