Not long ago, the safety of faucets became the focus of social attention. 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. Hiện tại, the faucets sold on the market vary greatly. The prices of similar products of different enterprises range from more than ten 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 view of faucets.
1, vẻ bề ngoài
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, Không bị phồng rộp, 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, Và không dễ để tuân thủ quy mô. Some faucet surfaces are coated with titanium, đồng (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, nguyên vật liệu
The body of the faucet are usually cast from brass and need to be sanded, machined, pickled and impregnated, pressure tested, polished and plated. Some manufacturers use zinc alloy instead to reduce production costs. Tay cầm, decorative nuts, three-way bathtub faucet switching valves, vân vân. are basically made of brass, Hợp kim kẽm, ABS engineering plastics; decorative cups are made of copper, thép không gỉ, nhựa; 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. Tuy nhiên, zinc alloy materials are not permitted in the national regulations for parts that are in direct contact with drinking water.
3, chức năng
The faucet has various styles and various functions, and is generally used for washbasins, kitchen sinks, bồn tắm, Mưa rào, and bidets for use. According to the function, it is generally divided into ordinary faucet, sensor faucet, thermostatic faucet, etc.For example, the inductive faucet has the function of automatically sensing the water. When the hand reaches the water outlet of the faucet, there is water flowing out, which is convenient, hygienic and more suitable for the toilet in public places.
4, hộp mực
The cartridge is the heart of the faucet and the ceramic spool is the best spool. Các sản phẩm có chất lượng tốt hơn đều được làm bằng lõi van gốm, trong đó có các đặc điểm của khả năng chống mài mòn mạnh và hiệu suất niêm phong tốt. Nói chung là, nó có thể được sử dụng cho nhiều hơn 30-50 million times. Low-grade products use copper, cao su và các con dấu khác, 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, vân vân. 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. Vì thế, 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, có hoặc không có vật cản. Kiểm tra các phần khác nhau của vòi, đặc biệt là nếu các bộ phận chính được lắp ráp chặt chẽ, Và không nên có cảm giác lỏng lẻo.
