Solutions to the problem of melamine boards lamination
How to solve the problem when melamine board appears.
1. Solutions to warpage of veneer: adjust the impregnation speed of base paper, modulate impregnating resin according to requirements; increase hot-pressing thickness gauge, control compression thickness; adjust the temperature difference between upper and lower pressure plates, so that the difference does not exceed 4 degrees Celsius.
2. Solution of polishing board sticking board: hot pressing temperature can be adjusted, release agent can be added when mixing, and better polishing board, such as chrome-plated polishing board, can be used.
3. Porous solutions to the surface of the sticker: it can increase the pressure to a greater extent, increase the volatile content and resin content of the paper; increase the content of modifier by 0.5%. In addition, check whether the impregnated paper is stored too long or improper.
4. Solutions for edge damage of board: select high-quality base material; check cutting tools regularly.
5. Solutions for surface water stain (wet flower): adjusting the moisture content of base material; adjusting the moisture content measuring instrument; adjusting the drying conditions of impregnated paper; increasing the temperature of hot-pressed board, that is to say, increasing the temperature of hot-pressed board by 5 degrees, and paying attention to the preservation of impregnated paper.
6. Solutions to Emulsion Spot Generation: Increasing Pressure of Hot Press Plate; Adjusting Sand Abrasion Rate of Substrate or Increasing Thickness Requirement of Substrate; Cleaning Polishing Plate or Replacing.
