(a) The phenomenon knocked the wall open and some of it even fell off.
(b) Reasons
1, the grass-roots dry, watering wet enough, making cement mortar water loss is too fast, resulting in low adhesion of the glazed tile and mortar; cement mortar or adhesive coating time is too long, the mud dried, can not afford a bonding effect.
2. The grass-roots level is not even, so that the thickness of the mortar is not even when it is plastered, and the shrinkage stress of the central pulp is inconsistent.
3. The glazed tile is not soaked in water before construction. The dry brick will quickly absorb the moisture in the cement mortar, resulting in dehydration of the mortar and affecting the setting hardening. Or do not dry after soaking.
4. Before the construction of the base or glazed tile, the brick floating soil was not removed, and the brick and adhesive were not combined.
5. When the construction mortar is not full and empty drums are formed. Or the mortar is too thick and the operation is overweight, so that the mortar sinks in and the water floats, weakening the adhesive force of the mortar. 6. After the mortar solidified, the moving glazed tile was corrected.
(III) Measures
1, according to the provisions of the treatment base, watering the wet wall.
2. Before the laying of the glazed tiles, remove the surface of the floating soil, soak in water and moist, and put it in a dry place.
3. Correct anytime and anywhere while inlaying, and rectify after mortar is closed.
4. When plastering, each glazed tile will be plastered evenly and properly, and it should not be knocked after it is pasted.
5. Clean up the wall in time after inlaying. Caulking must be dense.
Second, the glazed brick crack
(A) The phenomenon of cracks in the glazed tiles that are attached to the wall.
(b) Reasons
1. The quality of glazed bricks is not good, and the material is crunchy and has a high water absorption rate. Due to moisture expansion, the glaze of the bricks is cracked.
2. When using cement paste plus 107 glue, the plaster is too thick, and the cement solidifies and shrinks causing the glazed tile to deform and crack.
3, glazed tiles in the process of transport or operation of hidden damage and cracks.
4. Glazed tiles stuck in cold areas, etc. are affected by slurry fusion.
(III) Measures
1, choose a good quality glazed tile on the back to see the material fine, and the water absorption rate is less than 18%.
2. Soak the glazed tiles with water before sticking, and pick out the hidden injuries. Do not hit the brick surface hardly during construction to prevent hidden damage.
