Influence of Relative Humidity on the Moisture Evaporation of Monocomponent Water-borne Sealer for Wooden furniture under Forced Drying Condition

摘要

The moisture evaporation amount and drying velocity or monocomponent sealer on the maple-veneered panels as base materials, under the drying conditions of constant temperature of 30°C and relative humidity varied from 30% to 70%, were measured in this study. The results indicated that the moisture evaporation amount increased, and drying velocity decreased with drying time under the same relative humidity, while the moisture evaporation amount decreased with the increase of relative humidity. The drying velocities were remarkable different under different relative humidities. During the same period of drying time, the difference degree of moisture evaporation amount within the relative humidity range of 30% to 50% was smaller than that within the relative humidity range of 50% to 70%.
