1. The surface paper contains insufficient glue or localized resin in drying 2. The volatile content of surface paper is too low 3. The pressure of heat pressure is uneven 4. The material of the mattress is inelastic 5. The stainless steel plate indicates unevenness 6. The resin reacts too old. The method of solving the problem that the molecular is too large and the resin fluidity is large:
1. Improve the resin content of the surface paper or control the drying temperature, prevent the local resin from solidifying 2. Increase the volatile content of the surface paper. 3. Repair the hot press, improve the uniformity of the pressurizing surface. 4. Replace the mat material 5, stainless steel plate regularly. Regular polishing 6. Resin should be analyzed and tested. If the non-conformity index is required, stop using it. 2. There are wet flowers (water vapor) on the board surface, and the edge is more serious.
1. The volatile content of the dipped paper is too high. 2. The solvent used to print the wood grain ink or dye is not suitable. 3. The dipped paper after dipping is hygroscopic (regain)
the solution:
1. Reduce the volatile content of the dipped paper after drying. 2. Replace the solvent used for the ink (dye). 3. Pay attention to the storage of the adhesive film. Generally, it can be covered with plastic cloth. 3. The surface crack of the decorative board is caused by:
1. The resin reacts too tenderly, the molecule is too small, the resin is not cured completely, and the surface adhesive film contains too much glue.
1. Unqualified resin is stopped. 2. Appropriately increase the hot pressing temperature or prolong the hot pressing time. 3. Control the rubber content of the surface film paper. 4. Reasons for the delamination of the decorative board:
1. The volatile content of the film paper is too low, the local resin is cured when the film paper is dry, the resin content of the film is not enough. 3. The pressure is too low or the hot pressing time is not enough. 4. There is debris between the film paper. method:
1. Control the volatile content not too low, the drying temperature should not be too high, the time should not be too long, prevent the resin from partially curing, increase the rubber content of the adhesive film, increase the pressure, and prolong the heating time. 4. Pay attention to the pattern when laying the mold. Miscellaneous items 5. Causes of warpage of decorative panels:
1. Various base paper tissue components are uneven in thickness 2. The adhesive film contains uneven amount of glue, and the pressure is not uniform at all. 3. The method of insufficient cooling after heat preservation in the pressing process:
1. All kinds of base papers should meet the process requirements 2. Keep the resin concentration uniform, adjust the gap of the extrusion roller shaft 3, and cool down to 50 degrees to carry out pressure relief +
