摘要
聚焦既有外保温系统修缮加固技术中采用的灌注发泡聚氨酯材料,在理论研究的基础上,对灌注用发泡聚氨酯性能开展研究,通过对不同发泡倍数的发泡聚氨酯膨胀性和力学性能、使用性能进行检测研究,总结形成了灌注用发泡聚氨酯性能指标控制体系。
This article focuses on the injection foam polyurethane material used in the renovation and reinforcement technology of existing external insulation systems.Based on theoretical research,through the research on the expansibility and mechanical properties of foamed polyurethane with different foaming ratios and the study on the performance test of its application and through summarizing the research results,an index control system for the injection-foaming polyurethane has been established.
