1, look at the back of the swivel to see if the color is pure.
Generally, solid color is milky white, which can't be black or yellow, and there are black spots on the surface. The color of black and yellow proves that the brick itself has impurities. If there are more impurities, the density of the brick will definitely decrease, and it is easy to break and damage in the ordinary practical process.
However, it is not normal for the back of the brick not to be very white, which shows that zirconium silicate is used more. One of the national tests on the radioactivity of ceramic tiles is the practical amount of zirconium silicate raw materials. Zirconium silicate raw material can make bricks white and bright, but zirconium silicate raw material is also one of the main killers of radioactivity, so we must pay attention to it.
General regular manufacturers have national inspection report certificates. You just have to let them show it. Note: It must be a color certificate bound with a photo frame or the parameter description behind the product manual, not a copy of the inspection report. That thing can be forged.
2. See if the particles on the side of the tile are fine and uniform.
If the particles are large and rough, the density of the brick will be crisp, and problems will definitely occur during use.
Give a simple example: when you get a house, it is usually an embryo room. The walls are all cement and the surface is rough. When you use putty powder, the walls will be smoother and more delicate. Let's look at it by this standard.
3. Erect the brick and tap the brick body with your hand.
The crisper the sound, the better the quality of the brick. The duller the sound, the worse the density of tiles, and the worse the pollution resistance and durability of tiles.
If you buy polished tiles, touch the front of the tiles with the back of your hand.
The smoother the feeling at first, the less pinholes on the surface of the brick, and the higher the anti-pollution ability. As long as it is not used in the bathroom or kitchen, you don't have to worry about anti-skid problems.
5. Look at the gloss of the same color brick surface.
Generally, a large floor tile is placed on the inclined plate, and there will be spotlights or fluorescent lamps on it. You should see the shadow of these bulbs on the surface of the brick. The clearer the shadow, the higher the gloss of the brick, the stronger the hardness of the brick and the higher the durability. On the contrary, the more blurred the shadow of the light bulb, the lower the hardness of the brick.
6. If you buy antique bricks, touch the front of the brick body with your hands.
Feel whether the glaze on the brick surface is delicate with your hands, and then carefully observe whether the glaze particles are rough with your eyes.
When buying antique bricks, we must pay special attention to the quality of glaze, because glaze is the life and color is the soul of antique bricks, so we must compare experts in color to see if the color is pure, and it is basically no problem to choose a product with pure color.
Extended data:
The types of ceramic tiles can be divided into glazed tiles, whole tiles, polished tiles, vitrified tiles and mosaics according to their manufacturing technology and characteristics. Of course, tiles with different characteristics have their own best uses. If you know enough about tiles, you can make the best use of them when decorating your room.
Whole brick
The surface of the brick is not glazed, and the material and color of both sides are the same, hence the name. Full-body bricks are more wear-resistant, but the color is not as good as glazed tiles. Classification is divided into non-slip brick, polished brick and permeable brick. Scope of Application Halls, walkways and outdoor walkways are widely used, and are generally less used for walls.
glazed tile
Glazed brick is a kind of glazed brick. Generally speaking, glazed tiles are richer in color and pattern than polished tiles, and play a role in pollution prevention. However, because the surface of glazed tiles is glazed, the wear resistance is not as good as polished tiles. Classification is divided into ceramic glazed tiles and porcelain glazed tiles according to raw materials. According to different glossiness, it can be divided into matte and bright. Scope of application Bright glazed tiles should be used in the kitchen, not matt glazed tiles, because oil stains enter the brick surface and are difficult to clean. Glazed tiles are also suitable for bathrooms, balconies, etc.
Polishing brick
Polished brick is a brick made by grinding and polishing the whole brick. Compared with the rough plane of the whole brick, the polished brick is much smoother. This kind of brick has high hardness and is very wear-resistant. Based on the application of flower infiltration technology, polished tiles can make various stone-like and wood-like effects. Classification can be divided into infiltration polishing brick, micro-powder polishing brick, multi-tube cloth polishing brick and microcrystalline stone. Scope of application Except the bathroom and kitchen, most other indoor spaces can be used.
glass block
Vitrified brick is made of quartz sand and mud according to a certain proportion, and then polished until it is bright, without polishing. The surface is smooth and transparent as a glass mirror, which is the hardest of all tiles. Vitrified tiles are superior to ordinary glazed tiles, polished tiles and ordinary marble in water absorption, edge straightness, flexural strength and acid and alkali resistance. However, the vitrified brick is not perfect, and its defect is that the pores are exposed after grinding, and dust and oil are easy to penetrate. The classification is mainly floor tiles. Belonging to a polished brick. Scope of application Vitrified bricks are suitable for living rooms, bedrooms and walkways.
mosaic
Mosaic is a special kind of brick, which generally consists of dozens of small bricks to form a larger brick. Acid-resistant, alkali-resistant, wear-resistant, waterproof, strong compressive strength, not easy to break. Classification it is mainly divided into ceramic mosaic, marble mosaic and glass mosaic. Scope of application Because of its small size and rich colors, it is widely used in small indoor areas, walls and outdoor walls and floors.
