Check whether the shower pipe body and the electroplating layer on the surface are smooth and smooth. This is because, in humid environments such as bathrooms, the surface of the shower is generally chrome-plated, but the same is chrome-plated, and the process is very different.
A good pipe body is made of all-copper material, and the surface has to be polished, polished, dust-removed, nickel-plated, chrome-plated, etc. to ensure that it will not turn black, foam and fall off during use. Look, the brighter and more delicate the naked eye can see, the better the coating process is.
1. How to judge the electroplating quality of the shower head: take a breath on the shower head, the faster the recovery, the better the electroplating quality;
2. Electroplating layer: copper layer 10 microns (conductivity and adhesion), nickel layer 10 microns (corrosion resistance), chromium above 0.2 microns (surface brightness, decorative effect);
3. The national standard for electroplating corrosion resistance is level 8, and our shower head is level 9 (higher than the national standard).
4.Hold the tube body in hand to judge the quality of the material. The same chrome-plated shower, some unscrupulous merchants will use cast iron pipes to pretend to be copper pipes.
A simple way to judge is to hold the pipe body with your hand and release it after 2 or 3 seconds. If the mist on the pipe body If it stays around for a long time, it is likely to be a cast iron pipe. If the pipe body hardly changes after leaving the hand, it can basically be judged to be a copper pipe. In addition, the knocking sound of the copper pipe body is crisp and clear, while the sound of the cast iron pipe body is low and dull. Knocking is also a method to judge the material of the shower pipe body. 3. Whether the quality of the shower is good or not, the invisible place is the most important, so be sure to ask the merchant about the material and service life of the shower switch valve core. The shower switch spool is made of ceramics with extremely high hardness fired by special technology, and the service life must be reached.
