METHOD AND DEVICE FOR REPAIRING PLYWOOD PANEL DEFECTS

摘要

The present invention is directed to a synthetic patch application method and device in which synthetic patching material is kept cool while it is mixed in a static mixing tube, prior to application to plywood panels. The synthetic patching material is kept cool by means of a removable cooling jacket that is installed to remove the exothermic heat of reaction generated during the mixing process. The cooling jacket is removable and reusable, and may be easily dismounted and remounted when replacement, adjustment, or repair of the static mixing tube is necessary. The present invention thus provides an improved method of repairing plywood panels using thermosetting resin-based synthetic patching materials in which waste is minimized and time between replacement of static mixing tubes is significantly extended.

主权项

1. A method for continuously applying polymeric patching material to repair plywood panel defects after mixing heated resin and catalyst components in a static mixing tube to form the patching material, comprising extending the operating life of the static mixing tube by cooling the mixing tube to increase the setting time of the patching material so that the patching material either does not set, solidify, or block the mixing tube or need to be discharged during periods of interruption or non-use of the continuous plywood defect repair method.
