摘要
为保障危险化学品事故特种消防救援人员安全,本文运用整装喷淋试验平台,选取消防队伍广泛配备的2套不同品牌化学防护服、1套传统灭火防护服、1套新型灭火防护服,开展平行重复试验.分别使用传统网格统计法和图像识别方法计算染色区域面积,运用面料液密性试验平台研究不同喷射压力、不同喷射时间对灭火防护服液密性能的影响.结果表明:图像识别方法与传统网格统计法测得的平均染色面积相对误差率小于 10%,验证了该方法在此领域具有准确性、可行性.传统灭火防护服面料随着喷射时间、喷射压力的增加,染色区域面积增大;而新型消防面料在相同条件下染色面积更小.新型灭火防护服面料采用内侧复合双组份PTFE膜、外层涂布硅橡胶涂层的复合芳纶梭织布,相比于传统灭火防护服面料,增加了复合膜材料和硅橡胶涂层,抗液体穿透能力更强.
Abstract
To ensure the safety of special firefighting and rescue personnel in hazardous chemical accidents,this article uses a com-plete sprinkler test platform,and selects two typical models of chemical protective clothing,traditional firefighting clothing,and new firefighting clothing widely equipped by firefighting teams for parallel repeated tests.The area of the staining area is calculated using traditional grid statistics and image recognition methods,re-spectively.And use the fabric liquid tightness test platform to study the influence of different spraying pressures and spraying times on the liquid tightness performance of fire protection cloth-ing.The results show that the relative error rate of the average staining area measured by image recognition methods and tradi-tional grid statistical methods is less than 10%,verifying the accu-racy and feasibility of computer image recognition methods in this field.As the spraying time and pressure increase,the dyeing area of traditional firefighting clothing fabrics increases,and the liquid tightness performance deteriorates,while new firefighting fabrics have better liquid tightness performance under the same condi-tions.The new type of firefighting suit fabric is a composite ara-mid woven fabric with a two-component PTFE film on the inner side and a silicone rubber coating on the outer layer.Compared with traditional firefighting suit fabrics,it has added composite film materials and silicone rubber coatings,which have stronger resistance to liquid penetration.
