Teach you four ways to test the quality of ceramic tiles
Bathrooms are usually laid with tiles, and the choice of tiles is also very particular. The selection of tiles depends on whether the production process is good or not. Before buying, check whether there is a factory name, site name, product name, rating, number of grids, equivalent, trademark, date of production, and standards implemented on the product packaging box.
Dongpeng Tiles
According to different room requirements to buy tiles. For example, the wall surface of a kitchen bathroom can be made of smooth glazed material, which is easy to clean. The bathroom is made of non-slip matte material to prevent wrestling under wet conditions.
The question of whether or not to contain radioactive material is also a major consideration in the selection of tiles. Consumers can use the national mandatory standard for radionuclides of construction materials GB6566-2001 as a reference standard. It should be noted that many products in the market do not have radioactive material test reports, and some even if they are not national sampling inspection reports, but mostly send test test reports or commissioned test reports.
Tip: There are many types of tiles available at present, and the quality of tiles can be verified by the “see, hear, cut, and water†diagnostic method.
“Look†means that under sufficient natural light or fluorescent lighting, the bricks should be observed vertically at a distance of 1 meter. Obviously, the glazed defect pattern should be indistinguishable, lifelike, and there is no obvious lack of color, disconnection or dislocation. Defects; back shading, trademarks, etc., clear, complete, with little stencil or defects; a group of products placed on a plane vertically, to see if there is uneven phenomenon; choose a flat glass plate, Plastic panels, table tops, or ceramic tiles, with the side and front sides of the brick in close contact with each Other in parallel, and the flatness of the edges and the degree of warpage of the edges are observed. You can also close the edges of two bricks together to see if there are any gaps.
"Listen" is to use one thumb, forefinger and middle finger to clip a corner of the tile, and hang it easily. Another index finger taps on the lower part of the tile. If the voice is clear and pleasing to the ear, such as sound boring and astringent, it is inferior.
"Cut": Just look at the broken part of the tile. The fracture is fine, hard and brittle, and the color is consistent with the top grade.
"Water": The water droplets are on the back of the tile. After the water has spread, the tile that has been soaked slowly has a high density and is regarded as top grade.
Area calculation
The area to be paved should be calculated before purchase. According to experts, a lot of building materials stores have conversion charts, according to the area can be found in the required number of tiles, or according to the height and width of the tile wall, you can find the amount of tiles. At the same time, the tile box will also list how much a box of tiles can be tiled. For rough calculations, an area of ​​80 square feet can be calculated as 640 4.25-inch tiles or 320 6-inch tiles. When there is a loss due to paving, after the total number is calculated, the reserve quantity must be added.
Consumers who are not on the tiles should consult with them beforehand and ask for more comparisons. Don't just look beautiful or simply consider the price. The color of each box tile will be different, and it should be fully mixed before laying. It is best to buy the same batch of boxed tiles.
Tiles on the market can be sold in square meters or purchased on the block. There are more than 200 dealers on Shilihe Ceramics Street, consumers of bulk shopping may purchase at wholesale prices, and tiles in building materials supermarkets can be purchased in blocks.
Tip: buy tiles to guard against being lost, we must pay attention to one by one unpacking inspection, but also to watch the loading on the car. Some merchants show you first-class goods, and pick-ups are second-hand goods. In addition, it is also necessary to prevent the decoration workers from being child care and from showing up as a shield.
Science pavement
Tiles should be cleaned before the base, such as lime plaster on the wall, latex paint, wallpaper and other decorative objects, or dirt on the ground, be sure to clean, otherwise the cement mortar and the base layer bond is not strong; In addition, if the wall The body itself has cracks, and it should be properly treated before it can be tiled to prevent future cracks in the basic structure from becoming larger, leading to cracking or detachment of the wall tiles; also, for floors and walls where the difference in flatness or verticality is too great, Leveling treatment with cement mortar. The difference in the color of the tiles is also compared before the shop.
Second, the bricks should be fully flooded. Because wall tiles have a high moisture content, this feature must be considered when pasting. Before the tiling, the base layer should be fully moistened with water, and the tiles should be fully dried in the water for at least 20 minutes. Otherwise, the moisture in the mortar is rapidly absorbed by the dried substrate and tile and condenses quickly, which affects the adhesion fastness. Otherwise, the tiles will absorb moisture from the cement so that the cement cannot function as an adhesive.
The paving slabs shall be paved with cement mortar first, and the uncoated concrete shall be laid on the ground. After knocking, the cement slurry shall be applied to the floor tiles and spread on the ground. The diagonal positions of the four bricks shall be flush. The laying of the order is also stress. Posted floor tiles should be posted from the inside, such as the ground slope or floor drain, should pay attention to the direction of the slope to find the drainage; wall tiles should be laid from the bottom, for the sake of beauty, the bottom of the brick should be posted. After pressing the tiles, press the tiles. In addition, a wall cannot be attached to the top at a time to prevent the tile from being heavy and causing it to fall. Do not step on tiles for a short period of time.
In order to cater to the consumers who are pursuing new trends, some new technological methods have emerged in the market, such as tile adhesives, colorful caulks, and leave-joint paving. Tile adhesive (also called dry sticking method), tiles do not need to be pre-soaked on the base surface without wet, as long as the basic conditions of the pavement can be better, so that the operating conditions have been greatly improved.
