In the building materials market, counterfeit products can be described as difficult to prevent, especially ceramic tiles, which are difficult to distinguish. Then Xiaobian gives you five simple and easy-to-use methods to identify inferior tiles. Let's take a look.
Move one: see
See the brick surface with uniform color, good finish and smoothness, peripheral rules, and complete patterns. Extract a few pieces from the same batch. Compare the defects such as no color difference, no deformation, missing corners, etc., to the top grade.
Move two: Listen
With hard objects tapping, the more crisp the sound, the higher the porcelainity and the better the quality. You can also raise the tile, use your left hand to hold a corner, tap the lower part of the tile with your right index finger, such as the voice is clear, sweet for the top grade, such as sound boring, muddy for the next product.
Moves three: drip
The water droplets on the back of the tile, see the speed of water infiltration after spreading, in general, the slower the water absorption, indicating that the greater the density of the tile, the better the quality; vice versa, the faster the water, indicating that the density is sparse, its quality is not as good as the former.
Move four: ruler
The higher the accuracy of the tile side length, the better the effect after paving. Buying high-quality tiles is not only easy to construct, but also saves man-hours and accessories. With a tape measure, there is no difference in the size of each tile, and the highest precision is the top grade.
Moves five: security
Now the general large brand of tiles will be printed on the back of the brick bottom of the brand Logo, this is actually a security sign, not only the bottom of the tile is printed with Logo, polished bricks in the middle of the brick surface with a margin of 10Cm, there is a security signs The naked eye is invisible, but the logo of the tile is clearly visible with ultraviolet light. A careful comparison of the above five tricks, buy a good brick is an easy thing.

The production process of copper in China is dominated by copper concentrates and pyrotechnic smelting of blister copper. The status quo is that the processing capacity is greater than the smelting capacity, smelting capacity has greatly exceeded the support capacity of copper concentrate, copper concentrate resources and scrap copper imports are required. Statistics show that in the 21st century, the output of domestic copper concentrate has not been significantly increased, maintaining an annual output of 600,000 tons (copper content, the same below), by the end of 2007 will form nearly 3.7 million tons of smelting capacity, far exceeding By then China's copper concentrate resources and the protection of the capacity of the international market may provide the amount of copper concentrate. The production capacity of copper mines in China can only meet 40% of the smelting capacity.
