Determination of Plywood Bonding Strength by Boiling Test
Class II plywood: The specimen was immersed in hot water at 63 3 C for 3 hours and cooled for 10 MIM at room temperature after removal. When impregnating the specimens, all the specimens should be immersed in hot water and covered.
Note: Rapid inspection method of 63 3 C and impregnation for 1 h is allowed in factory production. The measured results multiplied by coefficient 0.82 are used as the bonding strength value of product inspection. However, when there is dispute between suppliers and demanders, the method of 3 h hot water impregnation is still used as the arbitration method.如无特殊说明，文章均为本站原创，转载请注明出处。If there are no special instructions, the articles are original, if you want to use or reproduce, please indicate the original source www.plywoodinspection.com,If you find that our articles infringe on your copyrights and interests, please email us at email@example.com in time and we will delete it at the first time.
