In the modern home decoration, the application fields of wall tiles are more and more extensive. However, if the wall is usually long, or if the humidity of the wall is high, the tiles can easily crack, fall off, and fall off. This not only affects the use of results, but also leaves a piece of unsightly "scars" on the complete wall and ground. If you encounter this situation, you may wish to use the following methods to repair: First, if the mortar is not loose, only the tiles fall off. After the mortar on the back and around the tiles are scraped off, a little cement is added into the 107 glue to form a paste, and a thin layer is evenly coated on the back of the tile. , press the tile later to stick firmly. 2. If the mortar is dropped together with the tiles, first lightly plucking some of the pits on the original foundation surface, re-embedding with mortar mixed with 107 glue, or using cement, E-44 epoxy resin, acetone, ethylenediamine (Available at the chemical store) After mixing at a ratio of 5:3:2:1, brush a layer on the base surface with a brush and press the peeled tile up until the mortar hardens. It should be noted that if the tiles only partially fall off, do not use force to hit the mortar on the foundation surface to prevent vibrations and loosen the original solid tiles.

Smic tiles
Classification by structure:
(1) Sugar: sugar calcium, gluconate, etc
(2) Citric acid, tartaric acid and their salts
(3) Zinc salt and phosphate
(4) lignosulfonate
Hardening effect
(1) Influence on strength, excessive incorporation will cause the concrete to remain unsolidified for 24 hours or even 72 hours, thus affecting the need for early strength of concrete and delaying the construction progress. No obvious effect was found on the concrete of suitable age.
(2) The effect on contraction, the appropriate use of the contraction has no significant effect. Excessive use will cause the top concrete to dry and shrink due to excessive water evaporation and shrinkage cracks.
(3) The effect on frost resistance durability is similar to that of concrete without adding retarder. [1]
