One, why does ceramic tile stay seam
1. Ceramic tile has the problem of heat expansion and cold contraction
The mortar of ceramic tile and stickup ceramic tile can exist the problem of hot bilge cold shrink, in the process that temperature or humidity change, ceramic tile and mortar can exist certain and retractile, if do not leave seam, can bring about ceramic tile to appear in the process of later period use drum or craze.
2. Ceramic tile product normal error exists
Although ceramic tile is mechanized production now, but in the process of product production, there will be a certain size error (error is too large to belong to the quality of the product), if there is no seam, it is easy to appear when the ceramic tile shop is not flat, affect the aesthetic tile shop after sticking.
3. There are errors in construction
Tile brick belongs to very high proficiency in a construction project, workers in the course of the shop is stuck, can't completely do the shop is stuck every piece of brick without error, workers in a bad mood, day and night, different situation, such as shop sticks ceramic tile, its effect will have difference, if no seam, also it is difficult to ensure that ceramic tile juncture, flat, influence of the beautiful sex of tile shop sticks!
4. Easier maintenance and replacement in the future
After the tile shop is pasted in the practical process, it is hard to avoid because of the pipeline maintenance and other reasons to replace the damaged, if left seam shop is pasted, the replacement is easier and more convenient.
Two, how does ceramic tile stay seam
We need the aid of a positioning cross in making a seam. In ceramic tile shop is stuck in the process, the cross is embedded or stand in between seam in fixed position, make sure horn-to-horn-cross is accurate alignment space, adjust size of aperture of ceramic tile among, make ceramic tile sticks neat and beautiful, the aperture between ceramic tile is consistent, even, and installation is quick and convenient, save Labour save time. If there is no positioning of the cross, even if the construction side has the idea of leaving the seam paving paste, but because there is no cross to fix the width, it can only rely on the eyes to estimate, it is difficult to ensure that the width of the seam is consistent, which greatly increases the difficulty of construction, will also lead to the width of the seam is not consistent, affecting the visual effect.
Tile cross
Under normal circumstances, a brick with a cross, the cross of 5mm if the brick is almost dry can be taken down and then used, generally can be used three times, so you can save some costs; But 3mm and 2mm cross is not easy to take down, otherwise it is easy to brick off, only after the brick completely dry can take down, so it is generally difficult to reuse, do not want to take down on the inside to fill the seam is not seen, it is recommended to buy according to a brick with a cross principle.
Generally 5.0mm for medium sized tiles 8.0mm for large sized tiles and outdoor tiles. Of course should also be flexible according to customer demand configuration, but to take into account the visual effect after the shop.
Three, the size of the gap
The size of the wall brick that hutch defends leaves seam to should be in generally speaking 1~1.5mm left and right sides, can come with wrapping bag as referenced object; Polished bricks range from 1.5mm to 2.5mm; Archaize brick leaves seam to be in commonly 2.5mm~4mm.
2. The ground tile gap is suggested to be like vitrified brick, etc., which is generally left in the 1.5-2mm or so when pasted; Glazed floor tile is in 2.5mm~3mm. The gap of floor tile won't be too big commonly, if too big word accumulates bilge very easily, affect cleanness.
