防火服用蜂窝夹芯结构织物的热防护性能测评
|
摘要
针对当前防火服普遍存在的笨重、闷热等问题,提出采用隔热耐高温、吸湿透气的蜂窝夹芯结构来改善其功能防护与热湿舒适性能。通过对蜂窝结构内在传热机制的分析,设计和制备了7种不同的蜂窝结构,选取当前典型的各层面料作为实验试样,综合考虑织物面密度、蜂窝夹芯结构种类设计了21种实验方案,并利用热防护性能测试仪对其进行热防护性能测评;进一步考察蜂窝结构的边长、壁厚、芯厚对防火服用织物热防护性能的影响规律。结果表明:蜂窝夹芯结构质轻且能满足热防护性能的要求,蜂窝结构的边长越小,壁厚越大,芯厚越大,织物的热防护性能值(TPP)越大,热防护性能越好。
In view of the heaviness and stuffiness of current fireproof clothing, a honeycomb sandwich structure with heat insulation, high temperature resistance, moisture absorption and ventilation was proposed to improve its performance of functional protection and heat and moisture comfort. By analyzing the inherent heat transfer mechanism of honeycomb sandwich structure, 7 different kinds of honeycomb sandwich structures were designed and fabricated. The current typical layers of fabrics were chosen as the experimental samples. Taking into account of the fabric weight and the sorts of honeycomb sandwich structure, 21 kinds of experimental schemes were designed. Thermal protection performance(TPP) tester was used to evaluate the thermal protection performance, and further the effect of side length, wall thickness and core thickness of honeycomb sandwich structure on thermal protection performance of fireproof clothing was investigated. Experimental results show that the honeycomb sandwich structure is light and can meet the requirements of thermal protection performance. The smaller the side length, the larger the wall thickness and the larger the core thickness, the larger the TPP value of the fabric and the better the thermal protection performance.
