When choosing to use melamine decorative paper in furniture production, it is necessary to first check whether the blank is flat and smooth before proceeding with the blank treatment.

　　After the sealing primer is completely dry, it can be lightly sanded with old sandpaper until it is basically smooth, and then filled with atomic ash to fill all the nail holes and obvious uneven gaps such as adhesive and seams. After the scraped putty is completely dry, it can be sanded using either a sand grinder or a sand belt machine. However, all flat workpieces must pass through the sand belt machine to ensure their flatness. And it must be sanded to a smooth and even surface, without any dust marks or droplets, fiber hairs, or large sand marks.

　　After the operation, it is necessary to carefully check whether the melamine decorative paper has offset printing and stains, and provide strict protection to ensure the final quality is intact.
