造纸 equipment can production 熔喷布 substitute/replace product, nano fiber 滤材做口罩效果 more 佳……近段 time, 越 越 more substitute/replace product versus 继出炉, let supply 紧张 熔喷布 market to new 路子.

记者 understanding to, currently already 开始推 toward market more 款“ new type 熔喷布” not only Raw Materials more add more 样化, cost combined 理, quality property can more excellent, in can made property strong/high features. 不, 受限于 medical grade production process/workflow made 约, new type 熔喷布推广至 lower amount still 存门槛.

造纸 equipment can 产“熔喷布”

“熔喷布 production capacity 受限, main/primary is is new equipment upper cycle less need semi year above, investment relatively large, method speed solution market supply 缺口. currently research development ‘ ultra- fine fiber wet method non 织布’, can using/adopting similar 于造纸 wet method non technology, use enterprise commonly used 斜网纸 machine simple renovation can production, production capacity can achieve fast speed improves. ”

3 month 13 day, 河南省科学院旗 lower 河南科 high chemical industry has company （ lower 称“河南科 high ”） inner, through more production 工序产出 “ ultra- fine fiber wet method non 织布”, by 工人们 formed 卷打包码放 in inner. company negative 责人崔国士博士 toward introduction, as is 该院近期 R&D new technology, this material already through in production 验证, day production capacity is 800kg. 河南科 high in cationic 科创园 new wet method non production positive in add construction, expected can in month inner formed, day production capacity 5吨, can production N95口罩300万.

伴随 demand amount increase, time core 层熔喷布 from small product formed dilute material, lower production “脖子”, in 崔国士看, “ ultra- fine fiber wet method non 织布” experiment/testing product already 经河南省 medical devices 监督检验 testing, combined GB19083-2010 medical grade anti 护口罩 technology requirements, is currently lower substitute/replace 熔喷布 理想材 material, can is understanding 熔喷布 and supply 紧缺情况 provide strip/profile new 途径.

“熔喷布 production is will polypropylene (PP) melt 化, filament manufacturing, process 不接触 water, belongs to dry method production. ultra- fine fiber wet method non is will non fine fiber, through technology formed 浆, again formed film, dry manufacturing 无纺布. ”他 table/sheet 示, comparison dry method manufacturing 熔喷布, wet method 布做出 像纸一样, fiber in liquid distribution non uniform, defect more less, lower product qualification rate more has 保障. in addition, wet method production using/adopting fiber more fine, 孔径 滤效果也会 more good. and 常规熔喷布 versus ratio, ultra- fine fiber wet method non can provide more good gas property can, more high strong/high degree, in addition also tool good resistant 油, resistant water, resistant features.

据悉, currently 熔喷布 short 缺一方面 is due to upper 游熔喷 polypropylene (PP) Raw Materials short 缺, 另一方面 is machine new upper production capacity consumption relatively 久. ultra- fine fiber wet method non upper Raw Materials use is polyester type product, currently market supply positive 常, cost high 于熔喷布此 front positive market price. meanwhile, this type of substitute/replace product new production capacity can made property strong/high. currently large separation enterprise has 斜网纸 machine, make has machine through 圆网, long machine renovation can 做. for/regarding machine plant/unit full enterprise, can achieve 直接转产.

熔喷布 more substitute/replace product 出炉

according to 崔国士 introduction, use machine production ultra- fine fiber wet method non 织布同样 using/adopting electrical principle 进行 滤, made formed product rear water obvious low can force. 不, currently types can water new type “熔喷布”也 already through testing, toward lower production.

in 位于河南郑州 龙湖 in 原工学院科技园 inner, show/display 一台该院 textile clothing/apparel industry research 院何建 new 教授团队 R&D nano fiber 滤材实验 machine, 而据何建 new introduction, currently technology already application in 江西, 宁波 区 production enterprise new 产线搭建, production capacity can day 12000平米, used for production N95口罩 mono day can 出产36万, production non medical grade 口罩 话 mono day production capacity can 达70万, expected 4 month 10 day new 产线就 can amount 产.

“传统 one-time property medical grade and N95口罩 main/primary 依靠熔喷无纺布 ‘静 electrical 吸附’ as is main/primary 滤手段. this type of 口罩接触 water and other material rear 会逐步失 静 electrical, 导致 滤效果 large decline. nano fiber gas 滤材不 use 依靠静 electrical 吸附, is utilizing material 理拦截, 依托‘ material 理孔径’ 滤 principle, is use more fine ‘网眼’达 to 滤效果. need product material structure by bad, make in full remove electrical rear efficiency can high stability property. ”何建 new toward introduction 称, nano fiber gas already in 河南当 药检 machine through testing, in water 里浸泡十 separation 钟, through high temperature add hot 处理, product 滤效果仅 from 95% drop to 90%, 且连续浸泡三次都 can stability in 90% above.

据悉, nano fiber gas and 熔喷布 production principle has essence difference. comparison 熔喷布 use gas wire drawing process, nano fiber gas using/adopting electrical wire drawing, filament more fine, this type of new product upper material not only made polypropylene (PP), need is can solvent understanding in solvent agent polymer, polyurethane ester, poly 苯烯烃, polystyrene (PS) and other can by use textile, product cost or relatively 传统熔喷布 more add low 廉. meanwhile, nano fiber gas production equipment using/adopting Domestic material can block production 组装, can made property strong/high, generally 四五十天就 can formed new production capacity.

据何建 new introduction, currently use nano grade property electrical electrical filament technology production already by Shanghai, and other enterprise more using/adopting. 而证券时报•e company 记者此 front 也报道, 浙江朝晖 滤 technology corporation has company production nano grade film material already 经启动 toward lower 游供货.

lower amount application still 存门槛

随 various type type 熔喷布 substitute/replace product 出炉, lower 游口罩 Raw Materials procurement is has understanding? for/regarding new material, production enterprise 接受程 degree also how to?

“我们 currently also has 关注 熔喷布 substitute/replace material 情况, has 听同行提起找 to combined substitute/replace product. ”3 month 初, 一家A股 upper company 位于江苏 口罩 production negative 责人王 strong/high toward 证券时报•e company reaction 熔喷布 procurement difficult issues, 不 当记者问 and company is 否会考虑 using/adopting 熔喷布 substitute/replace product 时候, to 出 否定答案.

王 strong/high table/sheet 示, positive 规口罩 production enterprise generally light easy using/adopting new type Raw Materials production, especially is medical grade type 口罩. is Raw Materials 发生改变, that enterprise production 口罩也 need overall again to 药监局 heavy new 走审批 process/workflow, full material, product heavy new 送检. make in currently 特殊时期, this 一送检审批 process/workflow need month time, process more long several month.

“就算 new material price 便宜, property can more good currently has method more 换. for/regarding enterprise 而言, currently production cost low low is key/critical, can 否抓住 currently machine 会窗口才 is issues core. ”他说.

采访 in new table/sheet 示, due to production medical grade need type 备案, 资质申请手续, more new material process/workflow comparison 繁琐, currently R&D production nano fiber 滤材, in lower more by application to use production.

“ its nano fiber 滤材并不 is new technology, is front 一直停留 in 实验室 stage/phase, has toward lower 游推广 amount 产. currently this type of material rigid rigid as is new material by market to, comprehensive application also need time. ”他 table/sheet 示, upper this type of new material property ratio 熔喷布 need good more, is product also is property can in 一 层次 upper. in currently medical grade demand amount 依然旺盛 情况 lower, related can add fast certification process, 简化手续, heavy new made industry standards, let more good more new technology to comprehensive 推广.

畸形 high already 现回落

面 for 熔喷布畸形 high market 情况, not only has substitute/replace product versus 问世, market production capacity already to obvious expand increase.

早 in 2 month 份, Shanghai already R&D 转产 熔喷无纺布 specialized material formed 功, can production 6吨, will force new increase one-time property medical grade 口罩近600万 sheet/slice /天. China investment 约2 100 million yuan in 北京燕山石化 and 江苏仪征化纤两家 enterprise construction 熔喷布 production already versus 继投入 production. its in 北京燕山石化 2 strip/profile 熔喷布 production and 3 strip/profile viscous production 线, can production 4吨N95熔喷布 or 6吨 medical grade 平面口罩熔喷布. in 仪征化纤 will construction 8 strip/profile 熔喷布 production 线, can production 8吨N95熔喷布, or production medical grade 平面口罩 raw materials 12吨.

in addition, 包括国恩 corporation, corporation, new textile and other more A股 upper company 近期也 versus 继宣布转产 production 熔喷布 or upper Raw Materials polypropylene (PP). 据天眼查 data 显示, 截至3 month 12 day, 我国熔喷布 related enterprise 共计347家, 2020 year 2 month new increase 112家, and year comparison, increase speed high 达3633%. 而口罩 and anti related enterprise 也共计38151家, 2020 year 2 month new increase 6114家, and year comparison, increase speed high 达1561%.

“近期熔喷布 price has 一定程 degree lower slip, comparison price also is relatively high water 平. ”王 strong/high for table/sheet 示, 3 month market has 熔喷布材 material 商报价 high 达50 10,000 yuan 每吨, currently market 平均报价 more in 35 10,000 yuan left right, ratio front high already has drop 幅, can market price upper trend already to made, overall 看熔喷布材 material market supply 紧张 局面 also is has obvious understanding.

他 table/sheet 示, although currently 随 国 inner 疫情缓 understanding, demand amount has 一定回落, outer 疫情情况依然布容乐观, export demand has obvious growth. “ this 几天几乎每 day can to outer mono, in 昨天我们 also to 一笔 自 Italy mono. ”3 month 14 day strong/high 接受采访时 table/sheet 示.

3 month 5 day, 商务部 outer 贸司司 long 李兴乾 table/sheet 示, belongs to trade product, China 政府未设置任何 trade tube/pipe made measures. 疫情发生以, 商务部 as is for outer trade tube/pipe 理部门, from published has 关口罩 and its production Raw Materials export ban, enterprise can according to market 化原则开展 related trade.

in 此背景 lower, in easy and other upper, upper company export related 情况也 formed is investment 者提问 hot 点.

因口罩 concept 股价翻倍 道恩 corporation in easy 平台回复时 table/sheet 示, company material for outer export, already to outer mono, export ratio large, excellent ensure inner demand.

蓝帆 medical table/sheet 示, company product will excellent supply inner market, currently 尚未洽谈 export 事项, rear will according to 实际情况确定 is export.

cationic medical in easy upper table/sheet 示, currently outer day heavy current situation, company increase for 欧美, Southeast Asia 区口罩 and other anti product export.

“ overall 看近期口罩国 inner outer comprehensive demand is has 趋于平缓 走势, front market is need solution has or issues, in obvious can to market for product quality requirements already upper day 程. ”谈 and front market mixed 杂, relatively more combined product 情况. strong/high table/sheet 示, time can obvious to market tube/pipe force degree already has add strong/high, 一 规模 relatively small combined 格口罩 production enterprise already difficult 以继续开 machine production.
