The choice behind is still up to you. It is recommended to learn to detect the tiles yourself.
Inspection methods:
1. can be tapped, the sound of crisp tiles porcelain density and hardness, good quality
(gently knocking with your hand on the floor tiles, if the tile issued a "poof, poof" sound that suggests that it is not enough sintering, the texture of the more substandard. (If a slight "thud" sound, its texture relative to the previous one in terms of hard)
(In fact, the method is very simple, with the hand to knock, high-density tiles knocked out of the glass crisp fragrance. And low-density tiles emit the sound of dull masonry.)
2. Measure the water absorption rate of the tiles, the lower the water absorption rate, on behalf of the tiles, the higher the intrinsic stability of the tiles, but also the more suitable for moisture or moisture content of the space (such as the bathroom, the kitchen), will not produce black spots and other problems
3. Pouring a cup of water on the back of the tiles, the water stains diffuse rapidly, indicating that the water absorption rate is high, and vice versa is lower
4. You can use a hard object to scrape Tile glaze, if you leave traces, poor quality
5. Look at the color of the tiles is not clear, with the naked eye to see if there are pinholes, pinholes are prone to accumulation of dirt
6. flatness of the tiles, the side is straight, paved easily, the effect is also good (visual method, the floor tile placed on a flat surface to see whether the four sides of the flat surface is completely coincide with the four corners of the tiles, and then the tiles are all right angles, and then the tiles will be placed in a flat surface, and then the tile, and then the tile. Whether they are all right angles, and then put the tile in the same species and the same type of tile to observe the degree of color difference)
7. Select floor tiles often see the material supplier on the ground to make a strong step, which can only show that the bottom of his tiles flat and can not be said to
Ming the quality of his tiles
8. in the ground to scratch a little bit, the poor tiles because of the density of the relationship between the tiles, exactly like a Chalk, scratch where all marks.
9. Focus on the "look". A look at the grade. Superior product is the best, third-class products and other external products are worrying; second look at the appearance and glaze
Surface. Good tiles without convex and concave, bulging, warping and other issues, the side straight face flat. Glazed surface is clean, no particles or color shades of different phenomena
Elephant; three look at the pattern. Patterns should be delicate, no obvious color leakage, misalignment, broken lines or shades.
10. Focus two in the "listen". With a hand of the thumb, index finger and middle finger clip tile corner, easy to hang down, the other hand index finger gently porcelain
Tile in the lower part, such as the sound of bright, pleasant for the top, such as the sound of dull, astringent turbidity for the second product.
11. Cut out the broken pieces of ceramic tile (generally can be broken to the store to have broken pieces of observation), look at the fracture. Fracture fine, hard and brittle,
color and lustre consistent for the best.
12. Water drops on the back of the tiles, the water spread out slowly infiltrated tiles density, as a top quality.
13. In addition to the color according to your favorite, you also need to choose carefully: first of all, take out any four tiles from the box, put on the flat ground to compare the four tiles are flat and consistent, tiles diagonally whether or not the place is embedded. Then is to use the palm of your hand to knock on the surface of the tiles, listen to the sound: the sound of good tiles is relatively low: the sound of bad tiles is bright, and there are obvious reverberations. Of course, from the sound to assess the good and bad is relative. But the first method of comparison is not to be taken lightly, the biggest difference between domestic and imported tiles is mainly in the consistency of the specifications of tile products.
14. A look at the glaze of the tiles, tile surface should be smooth, delicate; high-gloss glazed tiles should be crystal bright, matte and semi-matte glaze should be
soft, reflective uniformity. Can try to scrape the surface of the tiles with a hard object, if there are scratches, it is said that insufficient glaze, the surface of the glaze buffing
After the tiles will be easy to hide the dirt, it is difficult to clean up. Second look at the product size is standard, available calipers to measure the diagonal, irregular
Tiles in the pavement will not be straight, resulting in unattractive. Third, look at the deformation, can be observed directly with the naked eye, look at the product side straight face flat,
This product deformation is small, easy to construct, paving the brick surface is smooth and beautiful. Four look at the pattern, color pattern to be delicate, realistic, no
there are obvious defects such as lack of color, broken lines, misalignment
15. Look at the packaging. First of all, see if there is a factory name, address and trademark, so as not to buy "three no" products. Secondly, look at the product quality level and the size of the water absorption rate. Generally speaking, the lower the water absorption rate of the product, relatively high strength, frost resistance is relatively good. If the user to buy ceramic tiles are mainly used for paving or for outdoor walls, need to buy products with low water absorption, such as porcelain tiles or stoneware tiles. If the user buys the brick is mainly used for indoor walls, such as the kitchen, bathroom walls, you can choose a higher rate of water absorption products, such as ceramic tiles. However, it should be noted that such products against cracking, thermal shock resistance, pollution resistance and chemical resistance requirements are relatively high. Third, look at the friction performance of the product.
If users buy ceramic tiles for paving, they need to check the coefficient of friction and wear level of the product.
16. Look at the surface quality.
First of all, see whether the color is beautiful and pleasing to the eye, in line with their own aesthetic interests. Secondly, about 1 meter from the sample, under certain lighting conditions, observe the sample has no lack of glaze, cracks, smoke, fall dirty, glaze bubbles, spots, bumps and other surface defects; about 3 meters from the sample, observe the surface of the product there is no difference in color in order to get a rough grasp of the gloss of the product. Third, gently tap the sample with a hand or hammer, if there is a metal-like echo, indicating that the product structure is solid; if there is a muffled sound, indicating that the product may have structural layering defects.
17. Look at the shape of the product. First look at the actual size of the product and the labeling of the working size is consistent. Secondly, look at the product's degree of variation
shape, see whether the product surface is flat, whether the corners are straight.
18. Tile quality testing six methods
1, the tile back drops of tea juice or water, to be a few minutes, depending on the degree of diffusion of its water droplet inhalation, not absorb water or low water absorption rate is good quality.
2, knock on the tile to listen to the sound is crisp, the sound is more brittle, porcelain, the higher the density, hardness is good.
3, with a sharp object to scrape the tiles whether there are scratches, if there are scratches that poor glazing is easy to slip, the surface of the glaze after grinding, dirty tile surface will not be able to clean.
4, tile color, chromaticity clear, natural, said the degree of porcelain is high, chromaticity is not clear, porcelain is low.
5, when buying, within one meter to the naked eye to observe the surface with or without pinholes, if any, that the glaze is not fully integrated, easy to produce a buildup of dirt.
6, the warping degree of observation: the naked eye to watch the tile side is straight, if the warping situation is serious will affect the future solid tile.
19. Look at the white surface of the tile is appropriate, whether the color difference is obvious, whether there are cracks, pay special attention to check whether there are dark lines, look at the front of the tile and the edge of the glaze is full. Then look at the side of the tile to see if there are spots or blemishes on the surface glaze etc. If there are no such features, the quality of the tiles is more satisfactory. Second, listen. Will be two tiles gently touch, such as issued a "when when" the crunchy sound, it shows that its billet pressed tight, high density, good quality; such as the sound for the "puff" muffled, it is said that its billet texture is not dense, or have dark lines, its quality is poor. Third, press. Tile face to glass flat, press its corners to determine its flatness, because the more flat tiles, the better its quality, and vice versa. Finally, if consumers need to buy tiles in large quantities, it may be worthwhile to discard one or two tiles, ink drops on the back of the tiles to be observed, if the drops of ink are immediately absorbed, it means that its compactness is poor.
20: (1) size error, geometric size is the key to determining the merits of the tile, with a tape measure of the diagonal and four sides of the brick surface size and thickness can be judged whether the uniformity
(2) color difference, randomly open the box to check a few, put together one by one to compare the general difference is normal, if it is very obvious on the problem, but the color difference of the tiles of the different production batch numbers. Tile color difference, it is best to buy the number of one time to buy enough, otherwise it is difficult to match the color later consistent;
(3) cracks, cracks in the underglaze layer, the surface cracks;
(4) uneven, glaze, although the glaze layer is bright, but the glaze layer or the glaze layer of inclusions;
(5) spots, glaze color in the isolation of the color of the color of the mutation point;
(6) trauma, bruising or deep cracks with uneven edges.
21. Look at the appearance
First of all, according to personal preferences and functional requirements of the living room and the required field layout, from the floor tile specifications, color tone,
texture and other aspects of screening.
Good quality floor tile specifications size uniformity, thickness uniformity, floor tile surface flat and smooth, no bubbles, no stains, no pitting, color
Color distinctive, uniform glossy, corners without defects, 90-degree right angle, not deformed, pattern pattern clear, good compression resistance, not
easy to damage.
Look at the quality.
First, take out any piece from the box, see whether the surface is flat, intact, glaze should be uniform, bright, no spots, lack of glaze, bump phenomenon, around the edge of the regular. Glaze is not bright, astringent, or bubbles are quality problems.
Look at the degree of regularity. Take out a brick, two pieces of alignment, the smaller the gap in the middle, the better. If the pattern of the brick must be four pieces to put together
Come up with a complete pattern, should also look at the brick pattern is articulated, clear. These bricks one by one vertical, than
comparison of brick size is consistent, small brick deviation is allowed in plus or minus 1 millimeter, large bricks are allowed in plus or minus 2 millimeters
see the color difference. Will be a box of bricks all out, flat in a large plane, from a little far away to see the whole effect, regardless of white, its
other color or pattern, should be consistent color, such as individual bricks deep point, shallow point, this will be very difficult to see, affecting the whole decorative effect.
Second,
Look at the inner quality
The appearance is the first step, the second step is to detect the inner quality of the tile. Because the light looks good can not, but also look at the hardness, look at the abrasion resistance, look at the water absorption rate. These directly determine the service life of the tiles, are some very critical factors. Hardness: take a piece of tile to knock another piece, or with other hard objects to knock a brick, if the sound of the brick is crisp, loud, indicating that the quality of the brick is good, burned cooked; if the sound is abnormal, indicating that the brick has a heavy skin or crack phenomenon: heavy skin is the brick is shaped, the material air has not been discharged, resulting in the material and the material between the combination is not good, the internal cracks, can not be seen on the surface, only to listen to the sound can be identified. Abrasion resistance: abrasion resistance can not be determined by the senses alone, more likely to rely on some technical indicators. In many standards, with degree (also called wear resistance) is an important standard of judgment, it shows that the degree of wear and tear of the brick, generally speaking, can be divided into five degrees:
Ⅰdegree: the lowest rate of abrasion resistance, generally used for display, wall and very little activity.
II degree: the degree of wear resistance is greater than Ⅰ degree of tiles, mainly used in bathrooms, bedrooms and other environments without hard friction.
III degree: moderate degree of wear resistance, mainly used in places with high activity. Such as living rooms, kitchens, etc.
Ⅳdegree: high abrasion resistance. In the foyer of luxury homes, corridors and public **** place to use is very suitable.
V degree:
V degree of division does not have a clear concept. But theoretically, with super abrasion resistance, generally used in non-family environments, such as airports, stations and so on. Water absorption: water absorption is also a very important indicator of the process of tile use. The method of judging the water absorption rate of tiles is very simple, only need to drop a drop of water to the opposite side of the tile, see the speed of its absorption can be. Generally speaking, the faster the water absorption and penetration speed of the tile, the higher its water absorption rate, and vice versa, the lower. In general, tiles with a low water absorption rate have a denser texture and better quality.
