Sticking wall bricks is a very important step when we are decorating the house. If the wall tiles are satisfactory, they will fall off, which will have a great impact on our overall decoration effect. so how much wall-tile hollowing rate considered qualified it, then, small series to tell you about, what with the standard method wall-tile wall-tile hollowing rate of all of it.

First, how much is the rate of empty wall tiles


1. If the area of ​​the empty drum is more than 5% of the total or if it falls off, it will be unqualified (single empty drum area is less than 10 square centimeters)


2. According to the DB32 standard, the total hollow of the wall is controlled at 15%, which means that there are fifteen empty drums in one hundred wall tiles. The area of ​​each empty drum is no more than twelve square centimeters


3. Provisions on the hollowing rate of wall bricks in the Code for Acceptance of Construction Decoration Engineering (GB50210-2001): 8.3 Finishing of plastering bricks, 8.3.1 This section applies to the plastering works and height of interior wall facing bricks No more than 100m, the seismic fortification intensity is not more than 8 degrees, the quality acceptance of the exterior wall facing brick paste project with full-stick construction


Second, the method of attaching wall tiles


1. The first thing to pay attention to is to determine the height of the paving, especially in the bathroom, to avoid the exhaust fan, the ceiling of the device, etc., so the height should be noted; the second is the size of the wall brick and the floor tile should not correspond to each other. The difference is based on the height, scale and overall role to determine the paving method. The next row of bricks will not be posted first, and all stickers will be posted. The next row of bricks with slopes needs to be cut for each brick, and each piece is cut differently, so it should be post-posted. The mortar of the wall tile should be added with an appropriate amount of glue, generally 8 to 10% of the water, and the excessively added bricks of the glue are not flat. When the bricks with patterns are attached, the direction of use of the bricks should be adjusted so that the direction of the bricks is exactly the same.


2. When affixing wall bricks, it is necessary to pay attention to the horizontal and right angles between each wall tile. The demand between the sheets and the sheets should be kept flat. Secondly, after the paving, the disposal requirements of the edge strips should be recognized as flat at the high and low points of the wall tiles and the edges. degree. Before the wall tiles are immersed for 1-2 hours, after removing the air, use a blade or iron sheet to scrape the cement reinforced pulp (cement: paper gluten lime = 1:0.5) or add 107 glue on the back of the wall tiles. Grout. Paste in a row from bottom to top according to the shape of the word or the shape of the field. Clean the brick wall surface, level it with 1:3 cement mortar, smooth it, scrape it with iron, and ask the wall to be vertical and square. For white ash or other coatings on the wall brush, the gray skin and the coating should be shoveled off, and the exposed cement mortar surface should be roughened and wetted.


3. When affixing bricks, the cement mortar should be satisfactorily applied to the back of the ceramic floor tiles, and then spliced ​​with a rubber plaque. At the same time, check the calibration with a level gauge and wipe the surface cement mortar. A horizontal line or a vertical line is ejected on the scraped wall as the basis for attaching the first row of wall tiles. When paving a row of wall tiles, apply a long ruler to check the baseline to make the wall flat and the vertical and horizontal seams straight. The gap width should not exceed 1.5 mm. After laying a part of the brick, wipe the mortar on the surface of the wall tile with a dry cloth.


4. After the wall tiles are finished for 2 to 3 hours, use white cement to clean the joints. Use cement, sand = 1:1 (volume ratio) cement mortar, and the seams should be densely packed and smooth. Wipe the surface with cotton wool. Use soft and dry white cement slurry to fill the gap between the wall tiles. Then wipe the gap with a dry cloth and wipe the wall tiles clean.

I believe that everyone has seen the above-mentioned small series, the method of affixing the wall bricks and the method of affixing the wall tiles, and have a certain understanding. The control of the empty wall rate of the wall tiles is very important for us.

In order to prolong the service life of the sintering machine tail scraper, we adopt the advanced welding technology by high strength wear resistant alloy deposited on the surface of the parent that scraper, especially in the sinter material directly scour area, and set reasonable wear-resisting layer structure and stress direction, which greatly reduces the consumption of spare parts and maintenance cost.
