Abstract

The present study aimed at testing the benefits of protecting woodchips with an acrylic crusting product developed for the coal energy industry. In the test carried out, four conical wood chips piles were built, two consisting of fresh biomass, the other two of dry wood chips. A fourth larger pile was built as a reference. One dry and one fresh pile were superficially treated with 25 kg of protective acrylic solution diluted in 250 L of water, providing an average application of coating agent of approximately 85 g m−2, while the other two worked as controls. To monitor the piles’ temperature variation, thermal sensors were placed in the inner part of the five piles during their construction. Moisture content (MC) and dry matter (DM) variations in woodchip piles were recorded. The piles treated with the coating agent did not show any significant differences with the untreated piles: in wet material, the protective film slightly reduced the moisture dispersal from the pile from evaporation rather than limiting water intake from rain; in dry material, this confirms the inability of the coating agent to limit water intake from rainfall.

评估在露天堆放的木屑上喷涂涂层的效果

本研究旨在测试使用为煤炭能源行业开发的丙烯酸结壳产品保护木屑的益处。在试验中，共建造了四个锥形木屑堆，其中两个由新鲜生物质组成，另外两个由干燥木屑组成。第四个较大的木屑堆作为参照物。一个干木片堆和一个新鲜木片堆用 25 千克丙烯酸保护溶液稀释在 250 升水中进行表面处理，平均涂抹量约为 85 克 m-2，而另外两个木片堆则作为对照。为了监测桩的温度变化，在施工期间在五根桩的内部安装了热传感器。记录了木屑堆的含水量（MC）和干物质（DM）变化。使用涂层剂处理过的木片堆与未处理过的木片堆没有明显差异：在潮湿的材料中，保护膜可略微减少木片堆因蒸发而散失的水分，而不是限制雨水的摄入量；在干燥的材料中，这证实了涂层剂无法限制雨水的摄入量。
