摘要

<正>以热空气干燥工艺对喷涂两遍水性封闭底漆的硬枫薄木贴面家具板件进行干燥处理,漆膜固化后,用拉力法测试层间附着力强度。结果表明:影响附着力的主要因素是湿度,温度对其影响不大,优化热空气干燥工艺只能在一定程度上改善漆膜的附着力。采用空气温度为35%和湿度为50%的热空气对第l遍封闭底漆进行干燥,空气温度为35℃和湿度为70%-的热空气对第2遍封闭底漆进行干燥,可以获得较好的漆膜附着力。

Abstract

For the problems of high salinity and alkalescent clay soft ground improvement in south-east coastal land of China, this study analyzes the effects of salt concentration, acidity and alkalinity on cement-stabilized soil strength through experiment. The results show that the strength of cement soil is comparatively higher in alkalescent environment and the strength of cement soil is lower due to the obstruction of the pozzolanic reaction in acidic environment. With the salinity increasing, the electric double layer around soil grain surface becomes thin. The ion exchange are advantage to the reunite process. This process counteracts the strength decrease due to the acidity. Therefore, the salt concentration could influence the cement soil strength in acidity environment and not influence it in alkalinity environment.
