Jiyuan where the tiles are good
1, look at the back of the swivel to see if the color is pure, generally pure color display for the milky white (partial white), can not be black, can not be yellow, the surface is not black, black hair to prove that the brick itself has impurities, Impurities more than the density of brick is more down, usually in the course of practical problems prone to fracture, damage. But the back of the brick body can not be very white that is not normal, indicating that zirconium silicate raw materials used too much, the national test tiles have no radioactive one of which is the detection of zirconium silicate raw materials practical amount of zirconium silicate raw materials can make brick Whitening, but zirconium silicate is also one of the main killers of radioactive, be sure to pay attention. General manufacturers have a national test report certificate, you ask them to produce it, note: must be booked with the kind of color certificate book or product brochure behind the parameters that is not a copy of the inspection report, that thing is Can be forged.
, to see the side of the granules of granules are fine and even, the granules are large, rough, then the brick body density crisp, the use of the process will certainly be a problem, give a simple example: you get the house is usually the embryo room, wall The surface is very rough cement surface, when you use the putty powder after the wall is relatively smooth, delicate, and you use such a standard to see just fine.
3, the brick stand up, hand tapping the brick body, the more crisp the sound to prove that the higher the density of brick, the better the quality, the more dull the tones to prove that the worse the density of tiles, tiles, anti-fouling,
4, if it is to buy polished tiles (600 specifications above the tiles), hand touch the brick body surface (hand back touch), start to feel the more smooth proof of the brick surface of the pinhole less, the higher the anti-fouling ability, as long as Do not worry about non-slip problems in the bathroom or in the kitchen.
