Office Chair Degumming

For office chair degumming, first identify the cause and then take targeted repair measures. The common causes and solutions are as follows:

Causes of Degumming

• Glue Aging: Over time, the glue used in office chairs can degrade due to long-term environmental factors, resulting in reduced adhesion and eventual degumming. For example, some lower-quality glues may show signs of aging after a few years of use.
• Uneven Force Distribution: If an office chair is frequently subjected to one-sided force or incorrect sitting postures during daily use, it can lead to uneven force distribution across the chair. Over time, excessive pressure on certain areas can cause degumming issues.
• Issues with Tenon and Mortise: For office chairs with tenon-mortise structures, if the tenon and mortise do not match in size (e.g., the tenon is too large or the mortise is too small) or if the design is unreasonable, preventing a tight fit, loosening can occur during use, leading to degumming.
• Glue Compatibility and Quality Issues: Poor compatibility between the glue and the materials of the tenon and mortise can hinder proper adhesion. Additionally, if the glue is of low quality, its adhesion and durability will be poor, making degumming more likely.

Solutions

• Repair with Glue: Prepare tools such as glue, a brush, a cloth, and clamps. First, clean the degummed area of the chair with a cloth to remove dust and impurities. Then, apply glue evenly to the degummed area using a brush. Next, use clamps to tightly clamp the glued part of the chair to ensure a strong bond. Finally, wait for the glue to dry completely, which usually takes about 24 hours (refer to the glue's instructions for specific drying times).
• Re-adhesion (for Tenon-Mortise Structures): Reapply glue to the degummed tenon-mortise parts and press them firmly together. Keep them pressed for at least 24 hours to allow the glue to fully dry and cure. Once the glue is dry, the chair can be used normally again.
• Replace the Glue (for Tenon-Mortise Structures): If the glue used is found to be of poor quality, it is recommended to replace it with a better-quality glue. When selecting glue, consider its compatibility with the materials of the tenon and mortise, as well as its adhesion and durability, to improve the lifespan of the chair.
