1. Before splicing, check whether the splicing surface of the splicing plate is straight and consistent. If the splicing interface is not straight and consistent, there will be glue marks on the splicing, which will affect the quality of the splicing and the perfection of the seamless splicing. The simple way to ensure that the interface is consistent is to first place the two panels to be spliced on the same plane, make the two sides to be spliced as close as possible, fix them with F clips, and then use a positioning guide to fix them in the proper position, and use a gong machine at the same time. Cut the two sides to be spliced to obtain a flat and uniform splicing interface.
2. In order to make the front and upper ends of the splicing joints tight and seamless, wipe with 120# sandpaper below 2mm-3mm on the front of the splicing joints, then clean the joints with alcohol or Tianna water, and then check whether the splicing joints are flat and even.
3. At the front splicing edge of the two pieces to be spliced, use instant bonding to fix the splicing with small pieces of the plate, the number of fixed small squares and the distance from the splicing edge, according to the area of splicing and the selection of fastening tools. Certainly.
4. Put the prepared two boards on the same plane, and then stick a single-sided tape under the splicing interface to prevent the glue from dripping during splicing. Leave a 3mm gap between the two boards to ensure the splicing. Effectively control the glue, so that the glue at the splicing interface can be fully accommodated.
5. Pour the prepared glue evenly on the splicing interface. The amount of glue accounts for more than 1/2 of the reserved gap. Then use the F clip or A clip to fasten the spliced board surface as soon as possible, and check carefully when tightening. Check whether the spliced surface is flat, if not, use a rubber hammer to lightly hammer it higher than the board surface until it is completely flat.
6. During the curing time of the glue, all the fixtures should not be loosened or moved at will, and no one should stand on the table or place other heavy objects, otherwise the quality of the splicing will be seriously affected.
7. After the glue is cured, remove the excess glue with a gong machine or an angle grinder, and then grind it with a grinder. Never use a chisel to chisel the shovel, otherwise it will affect the quality and appearance of the splicing surface, and even collapse Missing, leaving hidden dangers.
The hardness of quartz plate can reach Mohs hardness level 7, so the seamless splicing and integration of quartz countertops has become a technical bottleneck that the industry and quartz manufacturers are eager to break through. Speaking of seams, let's take a look at how installers do seamless splices.
For the quartz processing industry, its hardness is second only to the hardness of diamond, and the raw material ratio is almost harsh. In addition to technical limitations, the quartz stone itself has too high hardness, and the particles inside will collapse. The mouth is relatively rough, and there will be gaps when splicing naturally. Seamless splicing is more difficult. Even if the quartz stone can be seamlessly spliced, it cannot be processed the same as the original after polishing and polishing, and there will still be stitching lines.
At present, to achieve seamless splicing of quartz stone, first of all, the requirements for processing equipment are very high. It is necessary to use a water jet to perform bevel anastomosis cutting (45° bevel edge is good). At present, there are CNC water jet cutting in the Chinese market. It has been used by large-scale countertop processors. After completion, use the original resin glue of the same color from the quartz stone manufacturer to paste it. Please do not use other glues indiscriminately. Before pasting, it should be matched with the color of the table top to avoid color difference, and stick it on the edges of the two butt joints with paper tape. In order to avoid unnecessary trouble when the glue contacts the plane and cleans it up. After finishing the preparation, apply glue evenly and use the F clip to fix it for about 20 minutes. Use a water mill to sand and polish the seams when finished. On-site splicing can use suction cup air pressure splicing machine if conditions permit. Warm reminder to avoid using a hand-held polishing machine for polishing on site. The darker the color, the more attention should be paid, because the surface of the quartz stone is polished by more than 30 large-scale high-speed water grinding.
