The veneer hot press is widely used in wood processing, decoration, building materials and other industries due to its easy operation and other characteristics. In use, attention should be paid to timely maintenance to avoid problems when using the hot press, especially in terms of cleaning. So, do you know the general methods for the maintenance of the veneer hot press?
1. Remove the hot pressing plate, use a steel brush to remove the rust spots, and then use diluted hydrochloric acid (concentration 15%~20%) to remove the rust spots, so that the pressing plate shows a metallic color.
2. Use 5mm422 electrode to surfacing in the corrosion area. Because surfacing on one side will form a zigzag plate, it is recommended to use surfacing on both sides to offset the stress of the welding piles.
3. Plane both sides of the surfacing pressure plate on the double gantry planer, and the planing amount is 0.5 mm.
4. If the plug welding is cracked due to gouging, excavation is required. That is to say, after the double-sided plane, each pressure plate should be checked one by one for the steam test pressure, and if there is water, mark it. After the experimental steam was extinguished, an angle grinder was used to form a long groove or a round groove at the water ball weld for surfacing.
5. Regarding the processing of PVC series, its line type and sticking force are incomparable with negative pressure equipment because of its high pressure, low temperature, and short film pressure time. When processing workpieces with negative pressure equipment (large area workpieces) ) deformation problem, so that the degree of deformation of the workpiece is greatly reduced.
