摘要
为了探讨环境条件对木家具底漆的水分挥发及封闭效果的影响,在5种自然干燥条件下,以枫木薄木贴面家具板材为基材,以水性封闭底漆为涂料,在分析干燥环境干燥能力基础上,用扫描电镜观察了涂层在基材上的封闭状态,用称量法研究了涂层水分挥发率和挥发速度。结果表明:水性封闭底漆封闭效果及干燥速度受干燥条件的影响明显。干燥30 min时,在温度11.2～13.2℃,湿度21.1%～23.4%,风速0.04～0.05 m·s-1的干燥条件环境中,水分挥发率为16.48%;在温度18.9～19.1℃,湿度54.1%～55.6%,风速0.03～0.15 m·s-1的干燥条件环境中,水分挥发率为2.23%;前者的封闭效果好。
The sealed state and moisture volatilization of a water-borne sealer for wood furniture using maple- veneered panels were determined for five different natural environments. Drying ability in different conditions was analyzed and the sealed state was studied with a scanning electron microscope （SEM）. The dried-water weight for moisture and the drying rate were measured using a water weight-loss method. Results showed that the drying condition greatly influenced the sealed state and drying speed. After drying for 30 min with drying conditions of temperatures of 11.2-13.2 ℃, relative humidity of 21.1%-23.4%, and air velocity of 0.04-0.05 m·s-l; the moisture evaporation rate of the sealer was 16.48%. However, with temperatures of 18.9-19.1 ℃, relative humidity of 54.1%-55.6%, and air velocity of 0.03-0.15 m ·s-℃, the evaporation rate was 2.23%. Thus, the sealed state with 11.2-13.2℃ was better than with 18.9-19.1 ℃. [Ch, 6 fig. 19 ref.]
