摘　　要：目的:为了解决高浓度毒气环境下防护面具所存在的问题,研制了MFT-2S型双罐大眼窗防护面具,进一步完善三级防护装具体系。方法:以MFT-2型面具为基础,整合其优势,在面罩下方双侧加装2套圆螺纹接头座组件及不锈钢卡箍(均为FMJ05面具组件),有效保证了固定强度。在通话器上装封口组件,将双罐分装两侧,并改装防雾镜片,适当增加滤毒罐高度。结果:测试结果表明,与MFT-1型面具相比,MFT-2S型面具吸气阻力减小一半,总质量减轻约50%,漏气系数0.005%,保明性能明显提升,防护性能比MFT-2型面具提高1倍以上。结论:根据换算的防护参数指标,说明MFT-2S型面具可以代替MFT-1型面具,实现面具的轻型化、简单化、标准化。Objective To develop MFT-2S protective mask with dual canisters and big-eye-window and to improve the three-grade system of protective equipment, so as to solve the problems on protective mask in environment with gas of high concentration. Methods MFT-2S protective mask was derived from MFT-2, with the advantages of MFT-2. The fixation intensity was effectively guaranteed by installing two sets of joint components and stainless steel clamps in the lower part of mask bilaterally. The sealing component was installed in communication component. Each canister was fixed at one side respectively. The fogproof lenses were reinstalled and the length of canister was increased properly. Results The resuhs showed that, compared with MFT-1 mask, the inspiration resistance of MFT-2S mask decreased by a half, its total weight became about 50% of MFT-1 mask, and the leakage coefficient of MFT-2S mask was 0.005 percent. Its antidim character was improved and MFT-2S mask had better protective performance than MFT-2 by twice. Conclusion According to the transformed protection indices, MFT-2S mask, with the advantages of being light, simplified and standardized, can take the place of MFT-1 mask.
