1、瓷砖有热胀冷缩问题
1. Ceramic tile has the problem of thermal expansion and cold shrinkage
瓷砖及粘贴瓷砖的水泥砂浆都会存在热胀冷缩的问题，在温度或湿度改变的过程中，瓷砖及水泥砂浆都会存在一定的伸缩，如果不留缝的话，会导致瓷砖在后期使用的过程中出现起鼓或者开裂。
Ceramic tile and cement mortar pasted with ceramic tile will have the problem of thermal expansion and cold contraction. In the process of temperature or humidity change, ceramic tile and cement mortar will have certain expansion and contraction. If there is no seam left, it will lead to bulge or cracking of ceramic tile in the later use process.

2、瓷砖存在合理误差
2. There are reasonable errors in tiles
瓷砖尽管现在都是机械化生产，但是在产品生产的过程中，会存在着一定的尺寸误差（误差过大就属于产品的质量问题了），如果不留缝的话，容易出现瓷砖铺贴时的接缝不平整，影响瓷砖的美观。
Although the ceramic tile is now mechanized production, but in the process of product production, there will be a certain size error (too large error belongs to the quality problem of the product). If there is no seam left, it is easy to have uneven joints when tile paving, which will affect the beauty of ceramic tile.

3、施工的工人施工的时候存在误差
3. There are errors in the construction of workers
瓷砖的铺贴属于熟练程度非常高的一个施工项目，工人在整个铺贴的过程中，不可能完全的做到铺贴每片砖的时候没有误差，工人的心情不好、白天和夜晚，等不同情况铺贴的瓷砖，其效果都会有差异，如果不留缝的话，同样很难保证瓷砖的接缝的平直的问题，影响瓷砖的铺贴的美观性。
Tile paving belongs to a highly skilled construction project, workers in the whole paving process, it is impossible to completely pave each piece of brick without error, the worker's mood is bad, day and night, and other different conditions of tile paving, the effect will be different, if there is no seam, it is also difficult to ensure the tile joint straight problem, shadow The beauty of the tiles.
