1. Key points of cutting process
When cutting EPS decorative lines, the choice of tools is crucial. You should use a sharp cutting tool that is specifically suitable for EPS materials, such as a hot wire cutter or a high-precision EPS-specific electric saw. The hot wire cutter can use the high temperature of the hot wire to quickly melt and cut EPS, and the incision is relatively flat and smooth, especially suitable for cutting complex shapes and curved lines. During the cutting process, the cutting speed should be kept uniform and stable to avoid too fast or too slow cutting that may cause uneven cutting or burrs. For example, for thinner decorative lines, the cutting speed should be controlled at 3-5 meters per minute. At the same time, the cutting size should be accurately measured and marked, and a certain processing allowance should be reserved, generally 2-3 mm, for subsequent finishing and polishing to ensure that the size of the cut lines meets the design requirements.
2. Key points of splicing process-interface processing
Before splicing EPS decorative lines, the interface needs to be carefully processed. First, clean the EPS surface at the interface, remove dust, impurities, etc., to ensure the cleanliness of the interface. Then, special EPS glue or adhesive can be used for splicing. When applying glue, it should be applied evenly and in moderation to avoid excessive glue overflowing and contaminating the surface of the lines or too little glue causing poor bonding. For example, use a toothed scraper to evenly apply glue on the interface surface, with a thickness of 1-2 mm. For larger splicing interfaces, the amount of glue can be appropriately increased, and the interface can be gently pressed after application to allow the glue to fully fill the gap and improve the splicing strength.
3. Key points of splicing process - fixing and reinforcement
After the splicing is completed, in order to ensure the stability of the eps decorative lines, fixing and reinforcement operations are required. Auxiliary fixing tools such as tape and clamps can be used to temporarily fix the spliced lines to prevent displacement before the glue is fully cured. For the splicing of longer or heavier decorative lines, additional reinforcement measures should be added, such as inserting reinforcing ribs such as bamboo sticks or plastic rods inside the interface to enhance the interface's shear resistance. For example, insert a bamboo stick with a diameter of 3-5 mm every 20-30 cm, and the insertion depth is about half of the thickness of the line, and then apply glue to fix it. This can effectively improve the overall strength after splicing and ensure the stability of the decorative lines during installation and use.
4. Finishing and polishing after splicing
After splicing, there may be some unevenness or excess glue marks on the eps decorative lines, which need to be trimmed and polished. Use sandpaper or a grinder to gently polish the splicing, and gradually transition from coarse sandpaper to fine sandpaper. For example, first use 80-100 mesh coarse sandpaper to initially polish off the protruding parts and unevenness, and then use 200-300 mesh fine sandpaper for fine polishing, so that the splicing and the overall surface of the line are smoothly transitioned without obvious splicing marks. During the polishing process, pay attention to uniform strength to avoid excessive polishing that damages the texture or shape of the line surface. Finally, the surface of the polished lines can be cleaned to remove the dust generated by polishing, and prepare for subsequent surface treatment or installation.
