Corrosion surface in hot-pressing plate processing must be very difficult, so how to remedy it? Kunshan Hongxin Hot Press Plate Co., Ltd., one of the manufacturers of Suzhou Hot Press Plate Processing, will introduce to you how to deal with the corrosion surface in hot press plate processing.
Hot-pressing plate is the main equipment used to produce rubber and plastic products, it is related to the quality of the product process; then when the surface of hot-pressing plate is corroded, it will directly affect the production, the answer is yes. And is it necessary to replace the corrosion surface immediately when it appears? It is known that the replacement of hot pressing plate is expensive, so in order to save capital, we can take certain measures to repair it.
1. After removing the hot-pressing plate, brush off the rust dust with a steel brush, and then remove the rust spots with dilute hydrochloric acid (concentration 15%-20%) to expose the metal color of the pressing plate.
2. Surfacing in corrosion zone with 422 electrode of 5 mm. Because one-sided surfacing can cause bending of pressure plate, double-sided surfacing should be adopted to offset the overlaying stress.
3. In the gantry planer, the overlay welded pressure plate is planed on both sides, and the planed amount is 0.5mm.
4. If the welding seam of the plug cracks due to planer cutting, it needs to be repaired. That is, after double-sided planer, each pressure plate will be tested one by one by steam pressure test, found that there are water droplets, do a good job of marking. After turning off the test steam, long grooves or circular grooves are grinded by an angular polisher at the weld seam of the water ball, then surfacing is done, and then polished by a polisher. Hot-pressing plate corrosion surface can be first aid, but the best measure is to do a good job of prevention, after all, no matter how good wound healing will also have scars.
