The manuscript entitled “Effects of Dehumidification Drying Environment on Drying Speed of One Component Waterborne Wood Top Coating” is creative in drying method and it is benefit to prompt the application of waterborne wood coatings in the furniture industry.

Waterborne wood coatings are environmentally-friendly surface decoration materials and used widely in the world, but their drying is a difficult problem in application. A drying process is necessary for the painting process in order to achieve a high quality coating, which is related to production cost, work efficiency, and popularization. Low temperature dehumidification drying is an environmentally-friendly and energy-saving process. An investigation of the effect of air temperature, relative humidity, and air velocity on surface gloss is conducted. The result of this research can provide a theory for the use of low temperature dehumidification drying on one component waterborne wood top coating, which can prompt the application of waterborne wood coatings in the furniture industry.

In this study, the effects of dehumidification drying environment including air temperature and relative humidity and velocity on drying speed of one component waterborne wood top coating are studied by Orthogonal experimental design and the results are analyzed creatively by Duncan analyses. It is found that during the dehumidification drying process, hard drying time is decreasing with the increasing air temperature and velocity and decreasing relative humidity. Air velocity is extremely significant to hard drying time, which is more significant than relative humidity, and relative humidity is more significant than air temperature. The difference of hard drying time is significant when the difference is 5min and above, and it is extremely significant when the difference is 10min and above, which are critical to judge the hard time in practice.
