1、第42卷第9期林业机械与木工设备Vo142No.92014年9月FORESTRYMACHINERY&WOODWORKINGEQUIPMENTSep.2014氯氧镁水泥与竹材胶合的力学性验研究王韵璐,许斌,黄金凤。伍佳伟,范吴博(南京林业大学材料科学与工程学院,江苏南京210037)摘要:竹材和新型材料氯氧镁水泥均具有资源可持续、性能优良和原材料丰富等优点。介绍了氯氧镁水泥与竹条、竹帘连接后的抗压强度、抗弯强度与胶层剪切强度的试验和检测工作,并将制得的竹/无机复合材料的抗压强度、抗弯强度与单板,无机复合材料进行比较,将其与膨胀珍珠岩水泥进行胶层剪
2、切强度比较。结果表明,氯氧镁水泥与竹材结合后,其整体性能优良,尤其是竹条/无机复合材料的抗压强度、抗弯强度、胶层抗剪强度均超过其他材料;对于竹材不同部位的胶层抗剪强度,竹黄无节处最大、竹黄有节处次之、竹青无节处再次之、竹青有节处最小。本研究对开拓我国竹材利用的新领域和提高竹材连接强度等方面具有较高的应用价值。关键词:氯氧镁水泥;竹质材料;抗压强度;无机胶黏材料中图分类号:TS612文献标识码:A文章编号:2095—2953(2014)09—0022—05ExperimentalSatudyonMechanicalPropertiesofMagn
