Recently, there are many varieties of shower heads on the market. From the appearance of the product, the surface of the shower head is like a mirror. But after you buy it and use it for a period of time, rust spots and even skin peeling will appear. If this problem occurs in the shower you just bought, it will really affect the appearance, and some poor-quality showers will also cause blockage due to paint drop .
Therefore, when purchasing a shower, you must carefully observe whether the surface of the shower is smooth or not. If it feels a little rough to the touch, you need to check whether the surface of the purchased shower has this problem. A shower with a good coating will help you save a lot of effort when you usually take care of it. Today I will tell you about the exterior coating of the shower head.
The quality of the shower coating not only affects the quality and service life, but also affects the usual cleaning and sanitation. Nowadays, most of the surface coatings on the market will choose chrome plating. A good coating can be maintained at a high temperature of 150 ℃ for 1 hour without blistering or foaming. Wrinkles, no cracks, peeling phenomenon; 24 hours acetic acid salt spray detection does not corrode. When choosing, you can see its gloss and smoothness. The bright and smooth shower shows that the coating is even and the quality is good.
Most of our commonly used faucets are three-layer electroplating. First, a layer of acid copper is plated to enhance adhesion, and then a layer of nickel is plated. The nickel layer is usually thicker to protect the faucet from corrosion. However, because the nickel layer is softer, A layer of chromium is plated to protect the nickel layer and improve the brightness. Therefore, each product should be processed with copper plating, polishing, nickel plating, and chrome plating.
Only suitable coatings that can withstand various corrosion and wear tests will have perfect performance. Good quality shower faucets can pass more than ten kinds of surface treatment tests, including corrosion resistance test, adhesion test, abrasion test and so on. The characteristics of chrome plating are wear resistance, no rust, lightness and high cost performance.
Therefore, when we buy a shower, the surface gloss of the shower must be even, and there should be no burrs, pores, oxidation spots and other defects. When buying a shower, you must feel it yourself.
