The inconsistent paste of wall tiles and the flatness of the paving have an important influence on the subsequent residence. In supervising the construction and acceptance, it is necessary to pay attention to standard procedures and ensure their quality.
Acceptance of the construction quality of wall tiles pay attention to three main points
1. First, look at the use and handling of decorative materials. The variety, grade, specification, shape, geometric size, finish, color and pattern of the tiles should meet the design requirements. The stone should be solid, uniform in color, no cracks, no discoloration, no water line or pollution, no warping on the surface, no trachoma . Bricks are free of defects, falling sand, holes, falling corners, cracks and other defects, the surface is square, uniform color. Paste materials, dry hanging accessories should meet the design requirements, carbon steel parts need to do rust treatment. The ground floor should be solid, clean, and of the correct size.
Secondly, it depends on the quality of construction. The surface of the facing layer is required to be smooth and clean, with clear texture, uniform color, no warp, no emptying; the gap between the facing blocks is uniform, and the filling is dense, straight, and uniform in color; Block pressure is correct, non-whole bricks are suitable for use, and are arranged in a straight line; protruding objects are applied with whole-plate cleaving, the edges are anastomized, neat and smooth, and the protruding thickness is the same.
The position of the hole is correct and the edge is neat; the direction of the flowing water is correct, and the drip line is straight; when the angle of the corner is 45°, the angle is correct and the lines are straight. Check the surface flatness error by 2m on the ruler less than 2mm, the vertical error of the facade is less than 2mm, the deviation of the joint height is less than 0.5mm, and the straightness of the upper end of the skirt is less than 2mm.
3. Third, we must promptly identify and resolve quality defects. After the construction of the wall tiles, the following quality defects are likely to occur. It is necessary to carefully observe and supervise the construction personnel to solve them in time.
1. Discoloration. Mainly because of poor quality of tiles, too thin glazes and improper construction methods. Tiles should be carefully selected during construction and clean water should be used to soak the tiles. Paste cement paste to use pure sand cement. Always clean the remaining mortar on the brick surface during operation. If the color difference of the tiles should be replaced.
2. Empty drum falls off. It is mainly that the bonding material is not full, the bricks are impregnated and the base layer is not treated properly. When hollow drums are produced, the wall tiles shall be removed to repair, the original bonded mortar shall be removed, and cement mortar shall be used to repair the mortar with a total volume of 3% of the qualified plastic.
3. The seam is not straight.

The twist drill is a Tool used to drill round holes in the workpiece by rotating cutting with a relatively fixed axis. Because of its chip slot into a spiral shape and the shape of the twist named. Spiral grooves have 2, 3, or more grooves, but 2 grooves are the most common. The twist drill can be clamped on manual or electric hand-held drilling tools or on drilling machines, milling machines, lathes or even machining centers. The bit material is usually high speed tool steel or hard alloy. Standard twist drill: The twist drill consists of the shank, neck and working part
We have five different materials,HSS-CO8%,HSS-CO5%,HSS-M2,HSS-4341,HSS-4241.From left to right there are from high quality to low quality.
