Water outlet effect of shower head: This is the most important and the direct embodiment of the technical ability of shower head manufacturers. Because even for well-known brands, considering the factors of cost, multi-functional blending or appearance, not all sprinklers can have a good water outlet experience, which is the case of all brands.
The shower with good water outlet effect, especially the multi-functional shower, has a certain technical content in flow channel design or water outlet nozzle layout, which is not as simple as it seems on the surface. The shower with reasonable internal structure design, under the same water pressure, the water impact is stronger and will not feel the prick feeling. The water surface has no scattering, the water spray is uniform and full, the shower is gentle without losing strength, and the bath is more comfortable and relaxed.
In addition, the shower with suction function is rich in bubbles in the spray, which makes the water more soft and comfortable. At the same time, it also has pressurization effect, and the shower feeling will be better. However, not all standard version suction shower products will have good suction effect, and some even have no effect. This has a great relationship with the technical strength of the shower manufacturer, so it is the best way to buy when you can test the water.
High quality surface plating process:
The high-quality shower is plated with semi gloss nickel, bright nickel and chromium on the refined copper body. In some cases, there will be a copper plating process before the first layer of copper products, which can improve the surface flatness of products and enhance the adhesion of electroplating, so as to improve the yield of electroplating.
Among the three coatings, the nickel layer plays a role in corrosion resistance. Because the nickel itself is soft and dark, another chromium layer will be plated on the nickel layer to harden the surface and improve the brightness at the same time. Among them, nickel plays a major role in corrosion resistance, and chromium is mainly for beauty, but it has little effect. Therefore, the thickness of nickel is the most important in production. For a normal shower, the thickness of nickel is more than 8um, and the thickness of chromium is generally 0.2 ~ 0.3um. Of course, the material and casting process used by the shower itself are the basis. The material and casting process are not good. It is useless to plating many layers of nickel and chromium. The electroplating performance required by the national standard is salt spray ass 24-hour level 9, which is the boundary between high-quality shower and low-grade goods.
The electroplating thickness of faucets produced by some manufacturers with small scale, poor equipment, weak technical strength or pursuing low cost is only 3-4um. This kind of coating is too thin and will not be used for a long time. It is very prone to surface oxidation and corrosion, green mold, blistering of the coating and falling off of the whole coating. The electroplating of this kind of shower cannot pass the salt spray test, and there is no test control link at all.
In addition, CASS test is used as the standard in some foreign markets, such as Japan and the United States. For more high-end brands such as toto, some products are required to meet cass24h.
Simple methods to identify the advantages and disadvantages of electroplating performance:
Look: carefully observe the surface of the product. It is better that the coating surface of the shower is uniform, flat and bright without obvious defects.
Touch: it is better to touch the product by hand, and there is no uneven or rowing particles on the surface of the shower; Press the surface of the shower with your hand, and the fingerprints will disperse soon.
