When cementing the wall tile, cement mortar is used as the adhesive. The water absorption rate of the wall tile is large. If the water is not immersed in advance, the porous ceramic tile will absorb the moisture in the cement mortar. The cement needs a lot of moisture during the curing process, because the water loss becomes no adhesive force and there is no strength, and the bricks and mortar with cement mortar come off together from the wall.
2. Why do you want to leave a seam when laying tiles?
On the one hand to eliminate the impact of product size deviations, on the other hand to avoid thermal expansion and contraction, causing products to squeeze each other, resulting in swelling or peeling.
3. How often do the tiles and floor tiles remain?
Polishing tiles are generally 1mm, tiles 2-5mm, antique tiles 5-8mm.
4. What are the reasons for the unsatisfactory pattern after the product is laid?
Most products have certain patterns and directionality, and they can be paved in a uniform direction according to the product pattern characteristics or the back logo pattern to obtain a satisfactory paving effect.
5. Do you use pure cement for paving tiles?
In order to prevent the cement from shrinking and causing a large tensile stress and cracking the tiles, it is advisable to use low-grade cement 325 or less, and 1:3 cement mortar to tile the tiles.
6. After the polished bricks are laid, is it worthwhile to advocate that the workers use the box to cover the brick surface in order to avoid damaging the brick surface during construction of other projects?
The water in the box dissolves and rots, and the decolorization penetrates into the brick. It is difficult to clean and decontaminate. The best method is to use a woven bag and other items that are not easy to decolorize to cover and protect it.
7. Why does the color difference exist after polishing?
Different positions may cause different light conditions after installation, causing visual color difference; construction does not look at the color number on the packing box; bricks of different batches and different color numbers are spread together; the product will be mixed when it is graded, and will be different Color bricks are mixed together, or their professional level is low.
8. Are tiles spread horizontally? Or vertical shop?
The horizontal and vertical paving of the wall tiles mainly depends on the size and structure of the space. If the bathroom and kitchen area is small, but the interior space is high, cross-paving can be used to visually connect the large space area and reduce the inner space; if the bathroom and kitchen are small, the vertical shop can achieve the effect of making up for visual defects. On the other hand, horizontal and vertical shops also depend on personal preferences.
9, when laying tiles, why do the seams cross over?
Spread the same plane with products of different working sizes, especially when the sizes of the products are inconsistent with different products

DIN928 stainless steel Weld Nuts, which are available in fine thread and coarse thread. Perform all kinds standard, such as DIN,ANSI/ASME ISO,JIS,Customized, products widely used in Heavy Industry, Mining, Water Treatment, Retail Industry, Food & Beverage, General Industry, Oil & Gas, Automotive Industry. Custom packing for export, carton packing or plastic bags, or according to your request. We have much stock of those items, more sizes and standards for your choice.
Weld nuts are a type of fastener that are designed to be welded onto a metal surface. They have a cylindrical shape with a threaded hole in the center, allowing for the attachment of bolts or screws.
These nuts are typically made of steel or other durable materials, ensuring their strength and reliability in various applications. They are commonly used in industries such as automotive, construction, and manufacturing, where a strong and permanent connection is required.
Weld nuts are often described as having a flanged or non-flanged design. Flanged weld nuts have a larger surface area around the threaded hole, providing increased stability and load-bearing capacity. Non-flanged weld nuts, on the other hand, have a smaller profile and are more suitable for applications with limited space or clearance.
Overall, weld nuts are an essential component in metal fabrication and assembly processes, offering a secure and efficient method of fastening.
