摘　　要：目的对生物防护材料抗微生物悬浮液和人工合成血液的穿透性能进行评价,为高危生物污染环境作业人员防护服的研制提供科学依据。方法参照ISO 16604测试方法,以噬菌体Ph-iX174、脊髓灰质炎病毒、枯草杆菌黑色变种芽孢及白色念珠球菌作为挑战微生物、人工合成血液作为渗透样品,检测TPU膜、TPU膜复合材料和PU涂层3种生物防护材料抗微生物悬浮液和人工合成血液的穿透性能。结果在常压和不同正压条件(1.75、3.5、7、14、20 kPa)下,分别经3种防护材料阻留作用5 min,均未检测出噬菌体Ph-iX174、脊髓灰质炎病毒、枯草杆菌黑色变种芽孢、白色念珠球菌,也未见人工合成血液穿透现象。结论该生物防护材料具有抗微生物悬浮液和人工合成血液穿透的功能,可用于相关防护服的制作。Objective To evaluate the biological protective materials against microbial suspension and artificial synthetic blood penetration, so as to provide scientific basis for developing protective clothing for personnels working in high - risk biological pollution environment. Methods According to the method of ISO 16640, bacteriophage Phi-X174, poliovirus, black mutation bacillus subtilis, candida albicans were used as the challengers, and artificial blood as the penetration sample to detect the anti - penetration against the microbial suspension as well as synthetic blood by 3 bio - protective materials （ TPU membrane, TPU compound material, and PU）. Results Under nonnal pressure and different pressures （ 1.75,3.5,7,14, 20 kPa）, the 4 microbes mentioned above were not detected after 5 min of obstruction by the three protective materials, and the penetration of artificial synthetic blood was also not found. Conclusion The biological protective materials have the capability of anti-penetration of microbial suspension and artificial blood and are suitable to be used for developing biological protective clothing.
