Explain the process flow of marbled melamine paper transfer film

Describe the process flow of marbled melamine paper transfer film 1. Material selection of marbled melamine paper Select the stone material suitable for processing sticker surface products. The selection of materials requires less cracks, blisters, holes, and any marble material with small deformation, and the color difference is not limited; artificial marble materials are the most suitable materials for processing paper surface line products, because artificial marble materials have no cracks, no blisters, and artificial marble materials Reinforcement, trachoma, and hole sealing treatment are required; granite materials can also be used for the processing of sticker surfaces, but granite materials are difficult to form and polish due to their high hardness, and are less efficient in production and processing. 2. Open the blank The selected blocks and leftovers are cut into blanks with the required thickness for processing. If there is a ready-made thickness of the blank, this process can be omitted. For materials with many cracks, the billet should be opened to avoid or follow the direction of the crack, and never perpendicular to the direction of the crack, otherwise the billet will have cracks, which will cause all materials to break. In order to prevent the blank with many cracks from breaking when cutting and dividing, the blank is reinforced with strong fiber mesh in advance, and if necessary, reinforcement is added. 3. The cutting board cuts the selected material into the length and width to be processed. Considering the particularity of the processing technology of sticker products, it is recommended that the processing length of sticker surface products should not exceed 1500mm for natural marble and 3000mm for artificial marble. Natural marble is more than 1500mm easy to break, and artificial marble is more than 3000mm easy to deform. The specific processing time is the most suitable, and the principle is that the material does not break and deform. 4. The processing technology of glue repair and reinforcement requires special attention to natural marble materials that are prone to breakage, surface cracks, holes, and blisters, and glue repair and reinforcement so that they do not break during line forming, rough grinding, and fine grinding. The sticker will not break after the finished product is processed; sealing the surface blisters and holes can prevent the product surface from bulging or denting after stickers. 5. Product modeling, rough grinding, and fine grinding ①Line product modeling, rough grinding, and fine grinding Use an automatic line machine equipped with 40#, 60#, 120#, 220# diamond forming wheels to shape, roughly grind, and finely grind the blank. grind. The surface of the line is required to be smooth, without waves, and without traces. The smoother the surface, the flatter the sticker surface will be. ②The modeling, rough grinding and fine grinding of arc plate products follow the modeling and processing technology of products such as stone, but sticker products must be finely ground to not less than 220# with arc plate rough grinding machine and automatic arc plate grinding and polishing machine. For a very smooth, smooth curved surface. ③ Solid column modeling, rough grinding and fine grinding follow the modeling and processing technology of products such as stone. The bare body solid column is best polished with rotary mechanical equipment, so that the surface of the column body is very smooth and the arc is smooth; the shape of the column foot and column head should be as simple as possible, with few grooves, 'V' grooves, and convex arcs below R10. , because the complexity of the surface shape not only increases the difficulty and production time of the sticker, but also affects the flatness of the sticker surface. 6. Cleaning and drying Use diluted cleaning solution to clean the lines to eliminate any substances on the surface of the lines that affect the adhesion of paint and paper. Dry the surface of the lines on the paper to remove the moisture on the surface of the lines. 7. Surface treatment Fill the 'problem products' with holes, depressions and cracks on the surface with marble glue to smooth and repair them. This step is not required if the surface has no similar low-pitched defects. If necessary, a primer can be applied to obtain a smooth surface. 8. Stickers Prepare the corresponding colored paper as needed, and buy them from the market or professional manufacturers. After brushing an appropriate amount of waterproof glue on the back of the colored paper, use professional equipment to roll and paste it on the light surface of the substrate. Paper printed with natural stone patterns or wood patterns is generally pasted on the lines with a wrapping machine. The stickers are required to be flat and have strong adhesion. 9. Apply glue on the whole visible surface of the attached paper by spraying, brushing or spraying a resin layer with a thickness of more than 1mm for several times. The resin glue is sprayed onto the sticked lines with a fully automatic spraying equipment. Resin glue can also be applied to the lines by hand. The quality of brushing glue should be flat, without bubbles, needle holes, pores, and the thickness of glue accumulation is basically the same. The thickness of the adhesive layer is preferably 2 to 4 mm. The gluing operation is the most important process of resin surface sticker products. The quality of the glue coating determines the quality of the product. It is best to use automatic spraying technology for glue application. Not only the quality of the sprayed products is very good, but the spraying efficiency is very high, and more importantly, it can prevent the employees from contacting glue-like substances and protect the physical and mental health of the sprayers. 10. Line reshaping The lines after brushing the resin glue will flow along the shape of the shape, and the phenomenon of glue aggregation will appear in the low recesses, resulting in the glue here being too thick and the shape of the lines not meeting the requirements of the processing shape. , so it is necessary to reshape the lines that have been brushed with glue to eliminate errors caused by glue accumulation. When the line is reshaped, install 120#, 220#, 320# forming wheels on the line machine,Complete line forming, rough grinding and fine grinding work. 11. Sanding and fine grinding: Sand the lines that have been brushed with glue. Sanding is to make the surface of the sheet smooth and at the same time increase the strength of the surface, and the thickness is uniform. 12. Grinding and polishing After the surface resin is cured, it is polished and polished. Use the automatic line grinding and polishing machine to complete the grinding and polishing of the lines. 13. Waxing If you want to improve the luminosity of the lines, you can wax and polish the lines manually with the help of an electric polishing machine. 14. Inspection The inspector inspects the product according to the inspection standard of the line and the inspection requirements of the sticker line. 15. The flexible packaging uses a coating machine to film the processed line products to prevent the products from being scratched and moisture-proof. 16. Relevant staff will go through the procedures for entering the warehouse and entering the warehouse, and hand over the product model.
