How can I identify whether wood glue product is good or bad? The water based wood glue manufacturer tells you that you can choose to use boiling or baking as the detection method. This method guarantees the quality of glue and quality of the factory. The manufacturer provides methods for testing the quality of the water based wood glue:
1. The moisture content of the board increases and decreases rapidly: the moisture content of the wood board is controlled between 8%-12%. When the plate is in good health in boiling water, the water content of the plate will rise rapidly, and after several hours in boiling water, the water content will reach a peak. During the baking process, the moisture content of the cardboard will decrease, so as to test the quality of the jigsaw glue!
2. Sheet tension, because of the moisture content of the formed sheet: After the assembled board is dropped on the ground for a few hours and then boiled, the wood will dry quickly. Sometimes when he is a good pot, he can open his own at the same time. If it goes directly into the oven, it will open faster, boil, and the degree of deformation of the baking plate is generally large, and it will directly have a large amount of cork explosion. This indicates that the moisture content drops rapidly and then deforms itself, because of the tensioned wood, this force is also a test of the quality of the glue part.
3. The surface color of the glue after boiling and baking will deepen, which means that boiling and baking accelerate the oxidation of the glue, and it can also be seen whether the glue is good or bad.
The above is the method for testing the quality of the jigsaw glue, sorted out by the jigsaw glue manufacturers. If you want to know more, please follow the official website of Youxing Shark!
