口罩 “心脏”熔喷布, to how 做出?
is what has machine also can export 罩, is is 缺口罩 core material: 熔喷布.
熔喷布 is core, in 根本没 has 货, 一天一 价, mono already from 原 2万 block to 30-40 more block.
short short month, very more enterprise 都转产口罩, 熔喷布 price tube/pipe price very large, is full 国熔喷布缺货缺 厉害, has this more 熔喷布 supply market, in in 熔喷布 step/link upper.
熔喷布 is what
剪开一 already use medical grade 口罩, 你会发现: has 三层, （ inner 层）吸 wet 层, （ in 层） core 滤层, and （ outer 层） retardant water 层.
因 is according to production 规定, medical grade 口罩至 less 包含3层无纺布（N95 grade 别口罩, structure upper optimization: （ in 层） core 滤 滤层层数 more more, thick degree more thick ）.
S层: polypropylene (PP) specialized resin （ China 石化）-无纺布厂-口罩厂
M层: high melt flow index polypropylene (PP) specialized resin （ China 石化）- modified plastics 厂（ anti 疫期间, China 石化攻关 production 熔喷布 specialized material ）-熔喷无纺布厂-口罩厂.
熔喷布, 俗称口罩 “心脏”, is in 间 滤层, can fine 菌, retardant 止病菌传播. 熔喷布 is types high melt flow index polypropylene (PP) is material, many 纵横交错 fiber machine direction 层叠而 formed film, fiber scope/range 0.5~10 micron, its fiber large has filament separation 之一.
lower is 拍摄 熔喷布 structure sheet/slice: （飞 nano 台式扫描 electrical 镜拍摄） 看 to sheet/slice is is 会担忧, 熔喷布空隙 this large, is how ring in 病毒 呢? although new type 冠状病毒 dimensions very small, in 100 nano （0.1 micron ） left right, is 病毒无 method 独立存 in, its 传播途径 main/primary has separation material and 打喷嚏时 飞沫, large small in 5 micron left right, this is its 一, 第二, 熔喷布 essence upper is types fiber device, has 病毒 飞沫靠近熔喷布 rear, by electrical in surface, method 透. fiber mechanism 示意图 口罩 S层 and M层尽 tube/pipe raw materials is polypropylene (PP) specialized resin, 但熔喷布 specialized material and other 无纺布 raw materials in production process and property can upper in very large 差异. 熔喷布▲ 熔喷布 how 熔喷布 specialized material is high melt flow index polypropylene (PP). polypropylene (PP) melt flow index high, 熔喷出 fiber fine, made formed 熔喷布 滤 property good. 熔喷布 specialized material 李英豪摄▲ lower 面看看熔喷布 how production 出: 
due to 熔喷布 Raw Materials polypropylene (PP) 取自石油, therefore enterprise in production 熔喷布 upper tool has advantages. is solution high melt flow index difficult 题, Shanghai 石化抽调 force amount R&D 团队开展 formulation research, testing analysis and large experiment/testing and other as, force equipment, technology types types difficult, 才终于 formed 功攻克 high melt flow index polypropylene (PP) modified production difficult 题.

据悉, through process optimization, Shanghai has short inner again increase 产约2吨, to day 产8吨熔喷布 specialized material. need 知道此 front inner 熔喷无纺布 relatively is small 众, year production capacity is 5.35 10,000 tons, 占无纺布 production capacity 1%, main/primary used for production 口罩, environmental protection material, clothing/apparel, battery film and other product.

据说 Shanghai 石化以往 product melt flow index, has 口罩熔喷布 specialized material separation 之一. for extrusion machine pellet cutting speed degree slow, cooling short, screw long degree and other hard parts 不足 挑战, company through renovation electrical system and system, use its it production water 槽, optimization and other, 想方设 method in has equipment conditions lower 进行紧急 renovation and adjustment, meet/satisfy production need.
inner 容延伸: comparison N95 口罩 and medical grade outer 科口罩 截面图, electrical sheet/slice can 清晰看出, outer 科口罩 熔喷布 thick degree is 156 micron, N95 grade 口罩 熔喷布层 thick degree is 521 micron, is outer 科口罩 3 倍. medical grade outer 科口罩截面图, nano 台式扫描 electrical 镜拍摄 N95 口罩截面图, nano 台式扫描 electrical 镜拍摄

[1] China 石化: formed 功, force 口罩每天 again increase 600万 sheet/slice!
[2] Shanghai in 线: formed 功! Shanghai 石化口罩熔喷布 specialized material day “ upper new ”!
