The appearance of the same two faucets, the amount of coppper is completely different: surface points leading formal processing method is that the main body is foundry cast into the desired shape, and then to the machining workshop processing, and then by the surface treatment and other processes , And with the valve core and accessories after pressure test factory,In case of high water pressure,.
In order to deceive the truth, steal the column: Although through the first method, said the weight of the method passed, is not it finished, no, some leading although the appearance of the same, the weight can also be, but there may be material problems, with The poor quality copper, stainless steel or other alloy material. The inspection method is: Use a knife or other hard object to scrape the screw on the inside of the faucet. Normal yellow copper is normal copper, and white or variegated colors are problematic. There is also a way to identify if the price of the faucet is lower than the weight of copper multiplied by the copper price at that time, it is absolutely problematic unless it is a disposal of old goods.
true and false, fake false true, half true half false: like basin mixer, may be faucet outlet and accessories are real copper, and the column may not be copper. Half-truth and half-trend showers are even more obvious. The body is cast from real copper. The tube part may be stainless steel or alloyed aluminum. For this phenomenon can be comprehensively used to test the above method.
In a word, to simply test the quality of the product is very simple, one can say that the second scraper three operators, businesses can not lose money to do business, in order to super-cheap, only shoddy. Believe in a word, the person who bought certainly does not sell is fine, cheaper than cost, must have problem. Can only look at the appearance, can not say the weight of online shopping business, a certain amount is not enough.
