6 Key Factors That Determine the Value of a Faucet
The surface of the faucet is generally brushed. The product coating has special process requirements and is tested for salt spraying for a specified period of time.No corrosion will occur during the specified period. If there is enough light, it can be picked up and viewed directly. The surface of the surface should be dark brown with no oxidation or corrosion and almost pore-free, with no scratches, no liquid coating, color and bright color. If you touch it with your hand, there is no flour, the grain feels sandy. Press on the top of the tube with your fingers. Fingerprints spread quickly and could not easily be weighed on the scales. Some of the faucet surfaces are coated with titanium and brass (gold plating) like gold electrophoresis paint. Electroplating paint electrophoresis or copper surface coating is usually very fast, the three types of specialists are difficult to identify.
The main components of the faucet are usually cast from copper and coated, inverted, acidified, pressurized, refined and coated Some manufacturers use zinc alloy instead to reduce production costs. Handrails, decorative nuts and triangular wrench tubes are originally made of brass, zinc coating and ABS rubber. The wall coverings are made of brass, iron and plastic. For nut connection and eccentric bonding, apples are made of brass, the above material is recommended Copper coating is safe and effective and has long-term corrosion resistance. The higher the cleanliness of the copper, the better the quality of the coating and the less damage to the surface. Zinc alloys have poor coating quality and corrosion resistance, while ABS plastics are the cheapest with poor coating quality. It can be identified by weight scale, surface scratches, and surface quality. Copper is heavier and tougher, zinc is lighter and softer, and plastic is lighter and softer. However, zinc alloy material should not be used for parts that come in direct contact with drinking water.
Faucets are available in a variety of designs and functions. It is commonly used for dishes, kitchen utensils, bathtubs, showers, and bidets. In terms of function, generally, there are standard types, input types, constant temperature types, etc.
The cartridge is the heart of the faucet. Good quality products all use a ceramic cartridge with strong resistance and good sealing performance In total, they can be used more than 300.000 ~ 500,000 times. Poor products are mostly copper, plastic, and short-life seals. But the price is lower.
The faucet should be clear on the surface and free from debris, holes, and smoke marks when touched by hand. The main component of a quality faucet is generally made of copper. Shaping, cleaning, scraping the surface of the acid copper and then nickel coating, chrome coating (three layers of coating). Typical materials are usually only nickel-plated and chrome-plated (two layers of coating). Standard products are subject to special technical requirements and do not corrode within a certain period of time through a medium salt spray test. Therefore, high-pressure products with the correct structure, uniform coating, and soft and vibrant colors can be kept as bright as new.
Gently turn the handle to see if it is light, springy and if there's any blockage. Check the various parts of the faucet, especially the large parts that are tightly packed, there should be no loose parts.
