Electroplating is the process of depositing a metal or alloy on the surface of a workpiece by electrolysis to form a thin layer of uniform, dense, well-bonded metal or alloy. Currently, the main electroplating processes on the market are chrome plating, nickel plating, and titanium plating.
First, chrome plating
Chrome plating is often used as a decorative coating for common faucet plating processes. It has high hardness and abrasion resistance, good gloss, in use for a long time to maintain the luster and prevent oxidation, has a strong passivation ability, can form a thin layer of a passivation film on the surface of the workpiece, so that it is not easy to change in humid air, in the case of acid, corrosion and other conditions can maintain its shiny appearance for a long time. It is also very stable in performance.
Second, nickel plating
Because of its high hardness, nickel plating is mainly used as a base, middle and top layer of decorative coatings. In addition, nickel-metal has a strong passivation ability comparable to chromium, it can quickly form a thin passivation film on the surface of the workpiece to resist the corrosion of the atmosphere and some acids, so the nickel coating has high stability in the air. Very high. However, its colors are silver and yellow. For the iron substrate, it is a cathodic coating and has a high porosity, so the corrosion resistance of the single layer is not high.
Three, titanium alloy plating
Electroplated titanium alloy has high strength, low density, excellent mechanical properties, good toughness, corrosion resistance, and other characteristics. The surface of the titanium-plated faucet is smooth as a mirror, and its golden color makes it look like natural brass. In the heat processing, easy to absorb hydrogen, nitrogen and other impurities, abrasive performance is not strong, complex production process.
Porcelain taps are made of alloy metal, covered with low melting point porcelain powder and sintered in a high-temperature vacuum porcelain furnace. Porcelain faucets combine the strength of metal and the beauty of porcelain. It is characterized by color, realistic appearance, smooth surface, strong abrasion resistance, no deformation, stable color, acid and alkali resistance. The surface of the faucet is treated with a porcelain process, and the nano-liquid polymerized silicon is evenly distributed on the surface of the faucet. After high-temperature treatment, the nano-scale film layer can greatly reduce the tension of the ceramic surface of the tap, so that the liquid was spherical in its surface. Not easy to hang dirt, easy to clean, fine texture, feel good.
Five, baking paint
Apply a primer and topcoat to the bottom of the faucet. After each painting, it is sent to the dust-free constant temperature paint baking room for electric heating or high temperature baking with high infrared to solidify the paint layer. The faucet on the piano lacquer after surface treatment of the lacquer, its gloss and delicate texture is unique, with infectious aesthetic features.
Six, brushed nickel
On the basis of traditional surface treatment methods such as electroplating, in order to meet the needs of modern people, drawing can be based on the needs of faucet decoration, under the textured form of the base metal, under the action of external forces, such as mechanical friction. The method of sanding rollers is to make several textures on the surface, such as straight lines, chaotic lines, threads, ripples, swirls, continuous and discontinuous lines, so as to achieve matte, mirror, three-dimensional, embossed. Special drawing is divided into stainless steel wire drawing, nickel wire drawing, etc.. The brushed treatment makes the faucet visually appear rough, while the feel is very delicate, showing a restrained beauty.
The faucet is something that everyone must touch every day. Its quality and shape is directly related to our health and aesthetics, so it is necessary for all of us to have some understanding of it.
