北单比分网直播:How to deal with high aluminum refractory brick gap
The technique of laying high-aluminum refractory bricks is very important, because its form can reflect its beauty. Usually, the more common problem is the gap. If you want to deal with the gap, you can get better results. You can choose from the following four aspects. Start.
1. Leave a joint of 10mm width every 3×6 meters. When laying, you can leave the rice strip between the seams. After the laying, take out the rice strips and fill with the 1:1 cement mortar to ensure the width of the gray seam is even. This can ensure that the plate gap of the high alumina refractory brick is 2mm, and the basic requirement is that the gap is horizontal and vertical.
2. After the seam is finished, a small amount of water is sprinkled on the surface layer to make the brick soaked close to saturation. The interval is about 15 minutes. Use the clapper and the wooden hammer to finish it in sequence, and move the board to level. After adjusting the gap in the order of vertical and horizontal, the gap is adjusted to be uniform, and the adjusted floor tile is leveled again.
3. After the jointing and filling work is completed, the seam is cleaned. After the brush is wet, the joint is 1:1 cement mortar at the seam width of 10mm, and the remaining gap width is 2mm. The method of 1:3 lime mortar is used for filling.
4. For unsuitable places, the scraper should be treated one by one. The seams of the paved high-aluminum refractory bricks should be uniform and uniform, and the brick surface layer should be dense, smooth and smooth.
