口罩需求爆发,除了丙烯价疯涨,这些仪器商开启疯狂模式
p style=" text-indent: 2em " span style=" text-indent: 2em " 4月15日,央视新闻报道:多国“口罩包机”密集来华,“上门自提”模式已开启!随着国外疫情的蔓延,各国防疫物资不足的问题十分突出。作为制造大国,中国成为各国采购防疫物资的首选地。近期,各国的“口罩包机”货运航班密集出现在北京、上海、天津、广州、深圳、郑州等国际机场。这些飞机中,有的是客机改货机,有的是平常难得一见的货机甚至是军机。 /span /p p style=" text-align:

3月31日,商务部、海关总署及国家药品监督管理局三部门联合发布《关于有序开展医疗物资出口的公告》,规定自4月1日起,出口新型冠状病毒检测试剂、医用口罩、医用防护服、呼吸机、红外体温计的企业向海关报关时,须提供书面或电子声明。承诺出口产品已取得我国医疗器械产品注册证书,符合进口国(地区)的质量标准要求。这无疑对口罩质量提出更严格的要求,对应仪器测试指标也成为必备。 /p p style="

text-indent: 2em " 如上文所述,医用口罩材料三层结构:纺粘无纺布(S层)+熔喷无纺布(M层)+纺粘无纺布(S层),最重要的是阻隔层即熔喷层,熔喷层的纤维直径比较细,在2微米左右,所以只有纺粘层直径的十分之一,这个对防止细菌、血液渗透起至关重要的作用,经过静电处理后达到所要求的过滤效率。 /p p style=" text-indent: 2em " 两层S纺粘层主要作用是支撑整个无纺布结构,对阻隔并没有太大的作用。如果S层过多,口罩就比较硬,而熔喷层M过多,则呼吸比较困难,所以从口罩呼吸的难易程度可以判断口罩的隔绝效果,呼吸越困难,则阻隔效果更好,但是,如果M层变为薄膜,就基本无法呼吸,所以,这也是一个技术问题。 /p p style=" text-align: center" img style=" max-width: 100%
