Shanghai Daoqin Plastics Co., Ltd.

in recent years, material technology most new development already improvement medical grade anti property can, in using/adopting nano material improve/increase property can, reinforcement antimicrobial property can and improves 配戴舒适 property.

PP无纺布材 material most 受口罩 production 商欢迎

polypropylene (PP) （PP） melting point low, is production 熔喷无纺布 most 受欢迎 polymer material.

in medical application areas, SMS三层无纺布 non combined used for production medical grade 口罩. it is composite/compounding 无纺布, viscous 无纺布 + 熔喷无纺布 + 纺 viscous 无纺布, 三层纤网 hot formed.

之 therefore combined viscous PP and 熔喷PP, is is it tool has different property can. front tool has high strength and resistant use property. rear tensile property can versus for relatively low, is due to fiber relatively small and fiber absorption surface relatively large, therefore tool has good wet function and retardant property can.

therefore, 二者结 combined can production property can more strong/high product, product also can retardant liquid and pellets.

nano material can improve/increase efficiency

due to full 球不时爆发 new type system 疾病, make research development more medical grade 口罩, provide more strong/high 保护.

nano material technology in different industry in obtain application, already used for medical grade production in. 一 学术 research table/sheet 明, use nano material can provide more good function, property, antimicrobial property can and wear resistance.

例如, especially 行政区 research and design NASK nano fiber can 口罩, is utilizing patent nano fiber technology manufacturing 出 一 types thin type 口罩, can is N95口罩 provide high degree 保护, tool has outer 科口罩 舒适 property.

use nano fiber is is it non thin, therefore tool has relatively high surface 积, can improve/increase efficiency. 口罩 can provide more design, from provide more high gas property and non light.

据 manufacturing table/sheet 示, in made as process in use formulation, formulation in in add antimicrobial technology, to function, from more good 保护佩戴者.

NASK N95 nano fiber already obtain USA safety and research （NIOSH） certification.  NIOSH隶 USA control and anti in 心（CDC）, negative 责批准 in as use anti equipment （PPE）.

总部于 USA nano fiber production 商Verdex provide nano fiber technology, 称 滤材 material series active property filament formed, 每根直径约2,000 nano.

this due to tool more more can use surface, fine and more has by to fine filament surface.

medical grade outer 科口罩 VS N95 type 口罩

medical grade outer 科口罩 and N95 type 口罩均 tool retardant and fine and gas solvent pellets function. 但 is, it between also is has many 差异.

medical grade outer 科口罩 usually 由面罩, parts, belt/tape and other parts processing formed, generally non 织造布材 material manufacturing formed, through to function. medical grade outer 科口罩 design non 紧密密封式.

combined 适 三层手术口罩应 tool has 三层: 一层 hydrophobic water can retardant water, liquid and liquid; 一层 in 间 滤层 can fine pellets; 一层 hydrophilic water can absorption water, liquid and liquid.

about/regarding medical grade outer 科口罩, need most important is, this design can through combined testing. it 们未经 USA 国家职业 safety research （NIOSH） certification.

N95 type is NIOSH USA 国家职业 safety research （NIOSH） certification 9 types pellets material anti 护口罩 in types.

anti and other grade is N95 grade table/sheet in NIOSH standards testing conditions lower, 口罩滤 material for non property pellets material （如 powder 尘, acid 雾, 漆雾, micro material and other ） 滤 efficiency to 95%.

meanwhile, N95 type in 嘴/鼻子 upper formed 紧密 密封, it need 进行拟 combined testing, through adjustment make its tool has 预期 密封效果.

N95 type by is is anti more solutions. however, 一项于2019 year 9 month published, 由疾病预 anti control in 心（CDC）赞助 new research 显示, outer 科口罩 in anti 普通流感方面 and N95呼吸 device has 效.
