If the home floor is not properly maintained, there will be many problems. First of all, it is necessary to find the reasons for these problems, so as to know which method to use to deal with it. The following Xiao Bian came to tell everyone about the home floor tile drums how to do and why the winter floor tiles will play drums.
What to do at home?
What to do with the floor tiles in the home : There are several reasons why the floor tiles bulge
1, if it is a floor tile and paving, this is easy to cause improper gap size (usually 2mm) the gap between the brick and brick is small, in general, the base layer is larger than the expansion and contraction of tiles (that is, both The expansion rate is different. This will cause the arching of the tile layer.
2. If you are laying tiles, if you do not evenly level the layer, this will cause empty drums.
3. Another reason is that the quality of the original cement floor on the floor tiles is not good, and it may be that the labels are low. This will make the cement on the floor tiles not well bonded to the original ground.
If you are in front of this situation then the best way is to choose to redo, or use dry shop method. When paving the bricks, first lay some slightly dry sand ash, and then behind the tiles, apply a layer of plain mortar (no sand) rubber hammers (professional bricklayers). Be sure to pay attention to the talents you can step on after 24 hours. , otherwise it will cause the second case.
Why Did Winter Tiles Drum
First of all, we must know that in the winter, the tiles are cold and brittle. There are cement mortars under the bricks. The thermal expansion and contraction lead to cracking. If empty drums are present, then you can make a noise by tapping.
1. The structure of the building has changed.
The building itself will produce a certain degree of settlement due to geological problems, so that cracking of the tiles may occur, and general cracking is a common line.
2, the basic processing of ceramic tile is not standardized.
For example, if you find that your house has empty wall cracks, delamination of the waterproof and napped layers on the walls, cladding of the pillars on the big core board, and simply laying tiles on the outside of the flue, these are not standard wall treatments. Is likely to be in the late expansion due to moisture absorption, this is easy to cause the tiles loose deformation cracking.
3, tile laying hollow.
Hollowing parts and non-hollow parts are due to the different coefficients of expansion of the cement mortar and tile, which may cause the deformation of the tiles!
4, the use of high-grade cement.
General tile paving with ordinary 425 # cement can be, if you use the cement number is too large, when the cement mortar condenses, the cement absorbs a large amount of water, this time it is possible that the tile water is excessively absorbed and it is easy to crack, It will shorten the service life.
5. There is no seam left or the seam is too small when the tile is laid.
The gap size is not properly handled (generally 2mm), the base layer is larger in expansion and contraction than the tile, and it is also cracked due to expansion. Tiles have thermal expansion and contraction, and paving must be done in the process of paving. If there are no seams, that phenomenon will occur.
6, before the tile is soaked in water.
Ordinary glazed tiles If you do not soak in the water before laying, or lack of time to soak the water is easy to cause lack of water absorption of the brick body, which will cause the tile cracking phenomenon after laying.
Summary: There are many reasons why the floor tile has been kicked into the drum on the floor tile in the home and why the winter floor tile is related to it. In addition to empty drums when paving, the same weather is also It will affect, so the choice of decoration season is also very important.
Industrial applications editor broadcast
Whetstone sintered corundum (ruby) : A kind of microcrystalline corundum product sintered at high temperature. It has a compact and delicate structure and high hardness and strength.
The products are rosy red. The products are small grinding wheel type whetstone, standard type whetstone and grinding head type whetstone. When grinding the workpiece, it can maintain sharp edge and stable geometry for a long time.
It is suitable for forming and grinding of instrument industry, precision parts, micro cutting tools, tools and precision abrasive tools, etc. The precision surface roughness of machining can reach about 0.05μm.
Product SPECIFICATIONS: flat sand wheel whetstone with diameter less than 100 for small grinding wheel type, whetstone with various geometric shapes less than 200*50*25 for standard type, whetstone with diameter less than 25 for grinding head type.
Grinding method
About diamond grinding paste, particle size from W40 to W0.5. W40 is the coarsest, with a large amount of grinding, and W0.5 is the smallest. It is used for polishing, and it does not anneal, and it can also grind the hard knife.
Method of use:
The coarse W40 abrasive paste applied to borotartar can accelerate and increase the grinding amount without annealing.
Then, AFTER the rough grinding paste on the knife is cleaned, W0.5 grinding paste is applied to the ruby or natural jade for polishing, and the effect thrown out is a mirror.
Green silicon carbide, white corundum, brown corundum of these three kinds of whetstone hardness is not enough, coupled with a little coarse particle size, easy to grind out the cross, and the other three kinds of whetstone in polishing, grinding will not annealing.
If the particle size is greater than 1000, there is no difference. It mainly depends on the grinding paste used. When the grinding paste of W1.5 is applied to the ruby with 1000 mesh, its grinding effect is the effect of the grinding paste of W1.5, that is, the effect of the whetstone with 2500 particle size
