VIGA lets you know the difference between a one-hundred faucet and a one thousand faucet.

What is the difference between the one, one thousand and one hundred faucets?

The faucet production process is mature, and the country has also established corresponding standards. Although the scale of each enterprise varies, the shape of the faucet varies, but the production costs of similar products are basically similar. At present, the faucets sold on the market vary greatly. The prices of similar products of different companies range from 100 yuan to more than 1,000 yuan. They are also faucets. Why are there such large price differences, and let us analyze them from the technical point of the faucet.

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, there is no corrosion within the specified time limit. In the case of sufficient light, the product can be placed in the hand and then stretched straight to observe. The surface of the faucet should be black as a mirror, without any oxidized spots or burnt marks; while no close-up, 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 ABS engineering plastics are 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 alloy is lighter and softer, and plastic is the lightest and softest. However, zinc alloy materials are not permitted in the national regulations for parts that are in direct contact with drinking water.

3, function

The faucet has various styles and various functions, and is generally used for washbasins, kitchen sinks, bathtubs, showers, and bidets for use. 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, cartridge

The cartridge is the heart of the faucet and the ceramic spool is the best cartridge. 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 30-50 million times. Low-grade products use copper, rubber and other seals, and have a short service life, but at a low price.

5, the 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 coated with acid copper, nickel and chrome plating (three-layer plating); ordinary products are generally only nickel-plated and chrome-plated (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 have a long history.

6, the 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.
