The production process of faucets is maturing, and the country has formulated corresponding standards. Although companies vary in size, faucets vary in shape, but the production costs of similar products are similar. The price of faucets currently sold on the market varies widely, and prices of similar products of different companies range from more than 100 yuan to more than 1,000 yuan. The same faucet, why is there such a big price difference? Let us analyze and analyze from the point of view of the faucet process.
1, the appearance of the outer surface of the faucet is generally chrome-plated. The coating of the product has prescribed process requirements and the salt spray test is conducted after a certain period of time.
There is no corrosion within the specified time limit. In the case of adequate light, the product can be placed in the hands of straight distance observation, the leader surface should be black light as a mirror, no oxidation spots, scorch marks; and close to see no air hole, no blistering, no leakage , Uniform color; touch without burr, sand; tap the tap surface with your fingers, the fingerprint quickly spread, and not easy to scale. Some faucets have titanium-plated gold, bronze-plated (imitation gold-plated), imitating gold electrophoretic paint and other methods. Plating electrophoretic paint or bronze-plated faucet surface corrosion is often very fast, and these three non-professionals are difficult to identify, but the general warranty card will specify the requirements of the faucet surface requirements.
2. The main components of the material faucet are generally cast from brass material, and are cleaned, turned, pickled and infiltrated, pressure tested, polished and electroplated. Some manufacturers use zinc alloys instead of lowering production costs. Handle, decorative nut, triplet faucet switch valve, etc. Basically use brass, zinc alloy, ABS engineering plastic; wall cover made of copper, stainless steel, plastic; connecting nut and eccentric joint, outlet nozzle housing brass, the above components Brass material is recommended. Products made of brass are guaranteed to have the best plating quality and longer corrosion resistance. The higher the brass purity, the better the plating quality and the less plating plating on the surface. Zinc alloy plating quality is poor, corrosion resistance is not good, and the use of ABS-based plastic production of the cheapest price, poor plating quality. Can be used to estimate weight, secondary surface scratches and surface plating quality and other methods for identification. Brass is heavier and harder, zinc is lighter and softer, plastic is lightest and softest. However, with the parts that are in direct contact with drinking water, the national standard does not allow the use of zinc alloy materials.
3. The function tap has a variety of styles and various functions, according to the use of points generally have washbasin, kitchen sink, bathtub, shower, bidet use. According to the function points, there are general, inductive, and thermostatic types. For example: The sensor faucet has the function of automatically sensing the water, and when reaching out to the faucet outlet, water flows out. It is convenient, hygienic, and more suitable for public places (high-grade) toilets.
4. The spool is the heart of the faucet, and the ceramic spool is the best spool. Ceramic valves are used for products with better quality, and they are characterized by strong wear resistance and good sealing properties. Generally, they can be used in an amount of 300,000 to 500,000 times. Low-grade products use seals such as copper and rubber, which have a shorter service life. But the price is low.
5. The surface of the tap should pay attention to the surface of the gloss, no burr when the hand touch, no pores, no oxidation spots are excellent. The main body of the high-quality faucet is generally made of copper. After being shaped and polished, the surface is plated with copper, then plated with nickel and chrome plated (three layers of plating); common products are generally plated with nickel and chrome plated (two layers of plating). The coating of the regular products has specific technical requirements, and through the neutral salt spray test, there is no rust phenomenon within the specified time limit. Therefore, the high-quality faucet products have the advantages of tight structure, uniform coating, and smooth and delicate color, and they can keep bright as new.
6. Handle gently rotate the handle to see if it is light and flexible, and whether there is any obstruction. Check the components of the faucet, especially if the main parts are tightly assembled. There should be no loose feeling.
