The tiles have been uneven? May have overlooked these places-beauty seam agent factory

In the previous article, we talked about the reasons why the tiles fall off. However, many owners at the backstage reported to the editor that when they were laying the tiles, the tiles were always uneven, and the tile surface or the joints had obvious flatness. Blemishes, what is the reason for this? We together look. Construction factors ■ Tiles that are not laid in the direction indicated on the bottom of the tiles will have a paving direction sign printed on the ground, and the plasterer needs to follow the direction of the arrow to do the paving. Paving in accordance with the direction signs can make the surface texture of the tiles more smoothly, and secondly, it can ensure that the edges of each tile are similarly tilted and the paving is relatively flat. Many home improvement bricklayers ignore the direction signs and do not follow the direction of the arrow to pave, and the joints at the corners are prone to be uneven. ■ The tiles can be positioned without tools such as level and vertical cone level and vertical cone to ensure paving. When the cement mortar dries out after paving, the floor tiles remain flat. If the worker is not standard in the paving process, ignore the lack of level and vertical cone for positioning, resulting in the tile paving effect is not smooth enough. ■ The small tiles with reserved tiles have slight deviations in length, straight angle, edge straightness and so on. If no seams are left, when the edge heights of the tiles are slightly different, the seams will appear uneven visually. ■ After the tiles are not hit on the ground, since the cement mortar is still in a semi-dry state, it is necessary to beat the mortar and press down to make the cement mortar evenly distributed under the tiles, which can prevent the tiles from being stressed when the cement is solidified. Uniformity affects flatness. ■ Cement mortar ratio error Cement mortar is used as an adhesive, and its ratio directly affects the bonding force. If the ratio is wrong, the proportion of sand is too high, or the adhesive is not added to the mortar, it will cause the cement mortar to not stick to the tiles and cause the floor tiles to upturn. ■ When the cement mortar is not spread evenly for tile paving, the cement mortar on the back needs to be spread evenly and fully. If cement mortar or tile glue, the uneven force of the tiles may also appear uneven in the later stage. Environmental factors ■ The building body itself will undergo a certain degree of settlement due to geological problems, and the degree of settlement varies from place to place, and uneven ground may also occur. ■ If the temperature difference is too large, the temperature in the north is too low, the moisture in the cement mortar binder will freeze, and the volume expansion will cause stress, which will damage the structure and strength of the cement mortar. If this happens, the tiles and the floor will not be well integrated, and the cement hydration heat will be concentrated under the tiles, and the tiles will bulge. High temperatures can also cause the tiles to deform. Floor tiles that use geothermal heating are also prone to deformation when exposed to high temperatures for a long time. ■ Thermal expansion and contraction. Under normal circumstances, when it is cold, the object will shrink, when it is hot, the object will expand. This is an object phenomenon. It is a normal natural law that people cannot change. Therefore, over a long period of time, the tiles will squeeze each other and cause the tiles to be uneven. Lighter ones will cause deformation and severely cause rupture. Other factors ■ Due to the high temperature firing of the ceramic tile back, the ceramic tile will have a weak back arch. Under normal circumstances, this weak upper arch will not affect the paving result. Nevertheless, pay attention to inspection before paving, and stop paving if the arching phenomenon exceeds the standard limit. Otherwise, the middle part of the tiles will bulge severely after paving, and even a 'small groove' will be formed between the tiles and the tiles will have to be reworked. ■ Tile tilt angle Tile tilt angle is also called floor deformation, mainly because the tiles are not burnt through. The ceramic tile formulation uses high-temperature materials, and the manufacturer has added low-temperature materials for fast burning. During the firing process, the burned low-temperature material wraps the high-temperature material and forms vitrification on the surface, but the internal material is not completely vitrified or porcelainized. Therefore, after paving, affected by the tensile force of the cement and the environment, the rebound deformation appears to be warped. Tips for paving ①Test the flatness when buying ceramic tiles. Generally, the flatness of ceramic tiles is mainly measured with vernier calipers, but in daily life, we can put two bricks together and stand together to see if there is a gap between the two bricks. If there are obvious gaps, it means that the flatness of the brick is not very good. ②Because the on-site supervisors cannot guarantee the flatness of the tiles, they must be supervised in real time. Once they find that the situation is not right, they must promptly ask questions. It is best to learn some basic paving knowledge by yourself or find a professional supervisor, so that problems can be solved in time. Pay attention to check the flatness of the hollow drum and the joints during acceptance. ③Purchase of tile adhesives, although the displacement of tiles and inequality in paving are inseparable from the tiles themselves, if some tile adhesives are used when paving tiles, this situation will be greatly reduced to a certain extent. occur. Buy tile adhesive and look for the US joint agent factory. The company’s strong ceramic tile adhesive (special for large slabs with great value), a trusted professional brand, uses the principle of chemical bonding, and is optimized by polymer modification. The products are strictly in accordance with the ceramic tile adhesive (JC/T -) Implementation of the new version of the industry standard, safe and environmentally friendly, non-toxic and harmless.
