Shanghai Daoqin Plastics Co., Ltd.

  from 疫情开始 to in, can 够出门 人 already use 掉 不 less 口罩, in lower this type of 口罩资源紧张 time 里, less enterprise is 临时抱佛脚, 紧急转产跨界支援, 才算数稳住 comprehensive 复工复产之 lower supply short 缺局面.
 
　　 however 我们也 need attention/notes, this in in 一 “安慰口罩”, 即 滤 indicators upper combined 格 口罩. in front, expert 指出, combined 格 口罩 can 吸附纸屑, can through this method for 口罩进行建议 甄别.
 
　　吸附纸屑 科研 based on 自于何处呢?
 
　　普通 medical grade usually 由三层组 formed, is SMS structure: is mono viscous 层(S层), in is mono or more 层(M层) 熔喷层. its in 熔喷层 use 熔喷布 is achieve medical grade 口罩 滤 property important step/link, main/primary is performance in machine 械 滤 methods, 当病毒 and fine in to 熔喷层 surface 时, in expand dispersion, 截留, property 碰撞, heavy force drop and other function lower, large separation by retardant 隔, 而洁净空 gas 则流入口罩 inner 层, 以供人们 positive 常呼吸.
 
　　但 is mono machine 械 滤效果 very difficult to medical grade for 病菌 滤 standards, electrical function by 提出.
 
　　经 驻极 熔喷布, for gas in non property small pellets material 吸附效果 large large improves. has 病毒 飞沫靠近口罩 surface, will by electrical 牢牢吸附, 而事实 upper is due to electrical add 持, medical grade 口罩 95% above efficiency can achieve.
 
　　而 improve/increase 口罩 静 electrical left right usually can separation is types: in 熔喷布 production process in through add electrical masterbatch achieve 口罩 静 electrical 驻极, and through equipment 改变口罩材 material structure formed 驻极处理. front 者 静 electrical 储存期限 can relatively long time, rear 者则仅会 in short time inner 保留一定 静 electrical electrical 荷. is currently due to masterbatch 紧俏, less 口罩 静 electrical 驻极处理仅 is equipment process upper 驻极处理.
 
　　 in production process in using/adopting masterbatch, will has 利于我国口罩 production enterprise in production process and product quality upper improves, currently has separation enterprise can provide masterbatch and positive in add strong/high for masterbatch production construction, Shanghai Di new material has company, positive combined poly new material has company, 南京华 poly plastics has company, in 科先行 engineering plastics engineering research in corporation has company, high anti-static has company and other.
 
　　 in addition, 广东美联 new material corporation has company in 3 month 11 day table/sheet 示, 拟投1.2 100 million yuan, construction 2 strip/profile 熔喷材 material, electrical masterbatch production and 9 strip/profile 熔喷无纺布 production 线. 届时, project will has 1 10,000 tons / year 熔喷材 material, 200 吨/ year electrical masterbatch and 8000 吨/ year 熔喷无纺布 production capacity.
