耐碱玻璃纤维网格布拉伸夹具研究

摘要

耐碱玻璃纤维网格布作为外墙外保温系统中重要的组成部分，其断裂强力的好坏直接影响到外墙外保温系统的优劣，影响外墙保温系统的保温及装饰效果。 GB/T7689.5-2013作为指导耐碱玻璃纤维网格布断裂强力检测的方法标准对拉伸试样的制备及试验进行了规定，基于提高网格布与夹具之间摩擦力，同时保证使耐碱玻璃纤维网格布不在夹具夹持处断裂的原则，设计出一种针对类似耐碱玻璃纤维网格布等软性材料进行拉伸试验所需的新型夹具，利用该夹具对试样进行试验，在保证检测结果准确性的同时，能够有效提高产品的检测效率。%Being one important part of exterior wall external insulation systems, alkali-resistant fiber-glass mesh’s breaking force influences directly performance of those systems, together with their effect of insulation and decoration. Using GB/T7689.5-2013, we carry on fiberglass mesh’s preparation and experi-mental studies on breaking force. A new fixture is designed in order to avoid founding of breakings at clamping based on promotion of fiberglass mesh with fixture’s friction. With the fixture, the experiment on breaking force of the soft material can achieve accurate result and efficient detection.
