Major factors determine the value of the faucet

View Count:98 CategoryNews in English

1. appearance

The outer surface of the faucet is generally chrome-plated. The coating of the product has the specified process requirements, and after a certain period of salt spray test,
No corrosion within the specified time limit. In the case of sufficient light, the product can be placed in the hand for observation at a straight distance. The surface of the faucet should be black as a mirror, without any oxidized spots or charred marks; and near no porosity, no blistering, no leakage plating , uniform color; touch no burrs, sand particles by hand; press the surface of the faucet with your fingers, the fingerprints quickly spread, and it is not easy to adhere to scale. 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 are difficult for non-professionals to identify, but the general warranty card will indicate the relevant requirements of the faucet surface.
2.materials
The main components of the faucet are usually cast from brass, sanded, turned, pickled and impregnated, pressure tested, polished and plated. Some manufacturers use zinc alloy instead to reduce production costs. Handles, decorative nuts, three-way bathtub faucet switching valves, etc. are basically made of brass, zinc alloy, ABS engineering plastics; wall coverings are made of copper, stainless steel, plastic; connecting nuts and eccentric joints, brass for outlet nozzles, the above components Brass is recommended. The quality of plating made of brass is guaranteed to be the best and the corrosion resistance is longer. The higher the purity of the brass, the better the plating quality, and the less the surface plating layer is corroded. Zinc alloy plating has poor quality and poor corrosion resistance, while the price of ABS plastic is the cheapest and the plating quality is poor. It can be identified by methods such as weight estimation, minor surface scratches and surface plating quality. Brass is heavier and harder, zinc is lighter and softer, and plastic is the lightest and softest. However, the parts that are in direct contact with drinking water do not allow the use of zinc alloy materials.
3. Function
The faucet has various styles and various functions. It is generally used for washbasins, kitchen sinks, bathtubs, showers, and bidets. According to the function, there are generally ordinary, inductive, thermostatic, and the like. For example, the inductive faucet has the function of automatically sensing the water, and the water is discharged from the outlet of the faucet, which is convenient, hygienic and more suitable for the public place (high-grade) bathroom.
4. Spool
The spool is the heart of the faucet and the ceramic spool is the best spool. The products with better quality are all made of ceramic valve core, which has the characteristics of strong wear resistance and good sealing performance. Generally, it can be used for more than 300,000 to 500,000 times. The low-grade products are mostly made of copper, rubber and other seals, and the service life is short. But the price is low.
5. Surface
The faucet should pay attention to the gloss of the surface, and there is no burr, no pores, no oxidation spots, etc. when the hand is touched. The main body of the high-quality faucet is generally made of copper. After being shaped and polished, the surface is plated with acid copper, then nickel plated and chrome plated (three-layer plating); ordinary products are generally only plated with nickel and chrome (two-layer plating). The coating of regular products has specific technical requirements, and through the neutral salt spray test, there is no rust within the specified time limit. Therefore, the high-quality faucet products have a strict structure, uniform plating, smooth and delicate color, and can remain bright as new.
6. Handle
Gently turn the handle to see if it is light and flexible, with or without obstruction. Check the various parts of the faucet, especially if the main parts are tightly assembled, and there should be no loose feeling.
