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. How to choose a cheap, reliable product, customers often lack expertise. The author has been engaged in the development of bathroom hardware accessories, common water taps, and infrared induction sanitary ware for many years and will now provide some experience about ordinary taps for customers to use when purchasing taps. → Related Links: About the purchase of faucets
1. Appearance
The outer surface of the faucet is generally chrome plated. The coating of the product has prescribed technical requirements, and after a certain period of salt spray test, there is no corrosion within the specified time limit. When the user purchases the faucet, under the condition of sufficient light, the product can be placed in his hands and can be observed at a straight distance. The surface of the faucet should be like a mirror, without any oxidation spots and scorch marks; No blistering, no leakage plating, uniform color; no burr and grit when touched by hand; tap the surface of the faucet with your finger, the fingerprint will spread quickly, and it will not easily adhere 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 users are generally difficult to identify, then you can ask the dealer to specify the requirements of the Faucet surface on the warranty card. → Related links: Home faucet installation and installation skills
2. Material
The main components of the faucet are generally cast from brass, cleaned, turned, pickled and impregnated, pressure tested, polished and plated. 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. Customers can use identification weight, secondary surface scratches and surface plating quality to identify when purchasing. 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.
