Shanghai Daoqin Plastics Co., Ltd.

我终于缓, this 几天提一口 gas material 憋文章, good good 讲一讲我们市面 upper Common one-time property medical grade made as process/workflow, and currently large most 关心 消毒 step/link —— factory is how 消毒.

起码三层

if 你 口罩裁剪开, can to has 3 层无纺布, this requirements is has production 规定, less 三层.

我们看市面 upper by light that type of 一戳就破 poor 质口罩, use 1 层无纺布, is 无良厂家严 heavy decrease material...

啥叫「无纺布」

「无纺布」（也叫「不织布」） is made as process 名, this type of material is textile 出. 我们常穿 各式衣 material, 棉, 麻, filament 绸总归 is in machine upper 横纬竖经 一点点 weaving molding.

而「无纺布」 is similar 我们做毛毡 针扎 method, has weaving 一说, is use N 根针齐刷刷不停 戳勾戳勾, let structure 纠结凝实 to 一起, rear formed this 么一层平面状 布 material. this is what 金贵 材 material, 爷爷奶奶 参 add year 人健康 active 动, separation to that type of 「 environmental protection bag 」, large more is use 「无纺布」做出.

that is what this more 天, also 会口罩紧缺呢? is market 关系就 is 供不应求... as is one-time property consumption product, full 国十几 100 million 人都想每天人手 need several, lower 子爆炸式 demand amount, again add upper Raw Materials supply 紧张, manufacturing large 国紧急复工, 昼夜赶工, 一时也 supply upper...

this 样 三层无纺布 raw materials, is lower this production machine combined in 一起.

has has attention/notes to this machine left upper this small 喇叭? has strip/profile 串线穿 喇叭口不停 往里送.

this need 看口罩 第二 structure: upper that can metal filament. 佩戴 时候 need combined solid to upper, this 样戴口罩才会严实, 不然没 this structure 话, this type of 塌鼻子漏风 is comparison heavy, 密封不严密, effect/influence anti 护效果...

看一 特写, is 沿 无纺布 一侧匹配输送 metal filament, rear lower structure 一卷边, rear again combined, 就搞定.

口罩主体部 separation is lower this structure, 拉开 完 full 罩住口鼻, large 也不怕.

this structure long this 样, this need has machine step/link.

就 is lower this machine design, has this sheet/slice can adjustment 斜面, setting good small 斜角, let large sheet/slice 无纺布沿 this several 斜面, 由 left to right 逐渐变 narrow 归拢出「折叠 structure 」.

接 also has pressure sheet/slice step/link, surface pressure 平整.

口罩 mono and 缝边, large more is full 自动无人工 处理. different is has fine micro manufacturing 差异, has is 缝边, has is hot pressure combined, small fine 节.

出 就 is mono 独 一 口罩主体. also 没完, rear also has good several steps 呢.

left right large 卷无纺布, and other need strong/high 口罩边沿.

一侧 by 包裹之 rear, pressure bonding.

this 时候出 原先 already 经裁断 good 口罩们, again by to 一起, this true is more 情空余恨, 此恨绵绵无绝期...

therefore also need 一 裁断补 strong/high step/link, 一刀两断...

in 口罩边沿 also need use upper viscous agent, lower this this machine 械爪送挂耳绳, that lower hot pressure viscous agent 挂耳绳 solid in upper, 如此一 一 平整 type 口罩就算 made as formed.

当然, rear also need 请出我们 「人工质检」. most 近 口罩 factory new 闻里我们常看 to 员工 扯耳绳 testing or 者整理口罩, has small can 爱担心无菌 issues, 放心啦, also need again 送 消毒灭菌~

打开式口罩

消毒之 front, again 看一 打开式口罩 made as, this type of is Common anti 雾霾口罩 or is anti specifications more high, ratio belt/tape 呼吸阀 that type of. lower 图 进 material non 常清楚, right 边 5 卷无纺布, is has 5 层 structure, color 转盘进 则 is 鼻夹处 metal filament.

消毒灭菌

说起无纺布, is is 也听老人家抱怨, this type of environmental protection bag 不结实, more use 几次就容 easy 破碎? low 无纺布 generally use high temperature method, is use 「 ring oxygen 乙烷」 this type of color gas 体杀灭 fine 菌, and true 菌.

找 一 动画演示图, formed 批 口罩送入消毒室, rear ring oxygen gas 体（ lower 图 黄 color is is high 亮, its color ）, to concentrated degree rear formed process. rear need in 消毒室里通空 gas and nitrogen gas dilute and ring oxygen 乙烷, more 次, to surface ring oxygen 乙烷残留 amount is 止.

mono 独密封 and formed 打密封

我们买 to 手 口罩 generally has mono 独一 密封 packaging and 一叠塑封一起 几联包, this types has what excellent poor separation, use amount 而定. is in rear 才封装, need is positive 规厂家 manufacturing, has production 信息, combined use standards, is combined 规.

口罩 has positive 反?

this type of most Common one-time property medical grade 口罩, has is positive 反面材 material 都一样, has is has separation positive 反面. positive material 会看起 more thick 实一, can anti liquid 体飞溅, more resistant use, in that 层算滤芯, that material more and. generally separation methods is 看挂耳绳朝哪边, has 挂耳绳 that is combined that 面.

heavy use 口罩?

谁都想 one-time use 完口罩就丢, 但买不 to true has method...我 this is heavy 疫区, 口罩根本就 is 断货, small in already is 每 1 户人家 2 天里 can 出 1 人 1 趟 procurement active product. in can is amount decrease/reduce necessary outer 出, 节省口罩 use 次数...
