山西地区日光温室建筑材料使用现状分析研究

Present Situation and Performance Analysis of the Energy-saving Material in Solar Greenhouses of Shanxi Region

【目的】调查研究山西地区日光温室的结构类型、建筑材料应用现状及存在问题,为当地建造日光温室选择适合的结构类型和材料提供依据。【方法】现场调研为主,查找文献资料、专家咨询等为辅。调研山西地区日光温室的建筑材料的优缺点、温室生产性能及造价等因素。【结果】调研区内日光温室的后墙以土墙、砖墙夹夯实土壤等材料为主;保温覆盖材料有PE发泡保温被、缀铝箔发泡聚乙烯保温被和草帘等几种。【结论】山西地区日光温室建设目前阶段仍比较适合采用土墙,但适宜的墙体厚度还需进一步分析与研究,新型墙体在该地区也有很大的发展前景;目前缀铝箔无纺布保温被使用性能表现较好,经济性一般,仍需要研究满足保温性、防水性、抗老化性、机械性并且有较好经济性的保温被;使用PE膜较多,应用评价不理想,建议采用EVA膜材料。

【Objective】The aim is to investigate the type of solar greenhouses in Shanxi Province,application status and problems,from which the type of greenhouses suitable for the development of local rural vegetable production will result. 【Method】The author carried out the census survey work with some methods,such as site investigation,querying literature,consulting experts and other auxiliary means to collect data.【Result】The results for the greenhouses in the research area were that,the types of the back wall body included soil wall and compacted soil clamped by brick; the insulation cover materials included PE puffed heat preservation quilt,polyethylene foam insulation decorated with aluminum foil and straws. 【Conclusion】Through the research on the advantages and disadvantages,greenhouse production factors such as performance and cost analysis of building materials in local area greenhouses,the conclusion was that whether the local greenhouse construction type with soil walls was suitable remains to be research,and the decorated foil insulation pad with non-woven fabric and EVA film structure were suggested for the future use.
