Home decoration, bathroom products need to purchase hardware, building materials market to look, then Lynx Mall and other online market comparison, prices vary greatly, the same one faucet (faucet what brand is good?) From 80 yuan to 2,000 yuan, a large shower from 250 yuan to 3,000 yuan or even to some of the ten tungsten wire dollars, a copper angle valve also from 6 yuan to 50 yuan per month, such a large price range, really let us get confused and overwhelmed.
Ask practitioners in this industry for more than 10 years of people that the original metal surface plating bath products is also a great learning, most consumers now buy sanitary products, such as faucets, large shower (shower what brand is good?), angle valve, floor drain, bathroom accessories and other materials only ask, for example, copper, stainless steel, zinc alloy, plastic, etc., but no way to grasp the standard plating, in fact, good plating product allows you to use for many years and remains shiny, poor plating generally used six Molybdenum tube or a year later began to emerge: not shiny, faded, pitting, blistering and other phenomena, the initial purchase is about the same, after the test of time, the merits of stand points, but then it was too late then regret .
Current general international electroplating various countries have different standards. Within the following criteria were included in: Chinese national standard GB18145, Europe EN817, EN248, United States and Canada ASMeA112.18.1 and Australia AS/NE3718, these standards which the EU is currently the highest standard, national standard GB18145 is to require an acidic salt spray test over 24 hours, roughly equivalent to 72 hours of neutral salt spray test, and EN248 requires 200 hours of neutral salt spray test.it implements the transistors, integrated circuits, resistors, capacitors, inductors and other components and electrical connection between the wiring, electrical insulation, to meet their electrical characteristics.Finally, for the PCB copy board electronic components assembly process inspection, maintenance provides identification characters and graphics, provides for the wave soldering solder graphics.
