Relationship between OSB organic volatiles and process parameters
The effects of drying temperature and moisture content on the emission of volatile organic chemicals (VOC) during processing of oriented strand board (OSB) were studied, and the effects of OSB compression time, temperature and resin content were compared. The test results clearly show that the drying temperature plays an important role in the emission of VOC from shavings. A positive correlation between the VOC emission level at the drying temperature, processing, and the corresponding OSB factory product emission level. The total amount of VOC increases as the moisture content and drying temperature increase. The results confirmed the fact that when a given moisture content of wood shavings is more air-dried in the surrounding environment than in the high temperature. However, processing low water content shavings at high drying temperatures will degrade the shavings and increase the level of emissions.
