The determination results of distillation method are not very accurate, and the cost of titration method is relatively high, so these two methods are relatively less used. Furnace drying or drying methods are often used in laboratories, which may take a long time to determine, but are relatively accurate. Electricity and infrared methods are commonly used in industry to determine the moisture content of wood. Here is a brief introduction to some current methods for measuring the moisture content of laminates in the laminate industry. Electrical testing can be used to detect wood density and moisture in industry. At present, the main detection methods applicable to production lines are microwave method and high-frequency method. The microwave method is based on the principle that the absorption of microwaves by a medium is proportional to the dielectric constant of the medium, and measures the change in the moisture content of a laminate. Although the calculation of moisture content, density, and wood grain angle of laminated plates using microwave method is relatively complex, the results of various parameters can be calculated simultaneously using a computer. Moreover, the microwave source energy is small, harmless to the environment, and the calculation speed is fast. The high-frequency method for measuring the moisture content of laminates is based on the principle that the dielectric constant and loss tangent of wood change with different moisture content. This method has been developed in recent years and has been tested on production lines. In addition to the two methods mentioned above, the methods for determining the moisture content of laminated sheets that are currently being studied and tested include infrared detection and line weighing. These methods are fast, accurate, and can obtain a large amount of data
