Shanghai Daoqin Plastics Co., Ltd.

◆ 截至2 month 底, day output/production volume 达1.16 100 million, relatively 2019 year growth 730%, 依然杯 water 车薪.

◆ 亚化 inquiry 剖析三 large causes large core raw materials 熔喷布 supply upper.

◆ 放眼 full 球疫情才 rigid rigid 开始, demand will belt/tape polypropylene (PP), polypropylene (PP) specialized material demand large growth;

◆ China and raw materials light forum will 于2020 year degree in 广西北海召开. 会议 also will industrial 参观考察.

◆ medical grade lower material development and application (polyolefin, PC, SEBS, PVC, ***橡胶 and other), will is forum focus/key point discussion inner 容之一.

3 month 2 day, 据国家发改委消息, China day production capacity output/production volume fast speed growth, di di breakthrough 1 100 million. degree, 2 month 29 day, 包括普通口罩, medical grade 口罩, medical grade N95口罩 in inner, full 国口罩 day production capacity to 1.1 100 million, day output/production volume to 1.16 100 million, comparison 2019 year day output/production volume 1400万 不 to water 平, large growth 730%.

2020 year 1 month 17 day, statistics published most new data 显示, 2019 year 末, China large 陆总人口140005万人, full 国就业人口总数77471万. according to full industry 50% 复工 rate 计算, 复工人3.87 100 million, as day 一天消 consumption 2 口罩计, need 7.75 100 million. is 说, currently 1.16 100 million day supply amount 依然杯 water 车薪.

随 口罩 production capacity output/production volume increase, issues 也随之而, in supply and demand balanced key/critical raw materials ——熔喷布 supply upper!

亚化 inquiry 观察, year front 熔喷布售价 in 1.2 10,000 yuan /吨 upper lower, rigid already 经4 10,000 yuan /吨起步, has in stock. rear price 步入跳 rise 通道, 一天一 价, 截至2 month 24 day, most high already to 70万 above 一吨.

that is what made 熔喷布 production capacity 释放? research 发现, causes has 三点,

A.      used for 熔喷布 specialized material production, polypropylene (PP) modified, improve/increase its melt flow index has machine oxidation material production capacity 不足;

B.    熔喷 equipment investment 昂贵, key/critical parts in 缺口, equipment cycle long, production capacity 释放滞 rear;

C.    驻极体断货, in market upper has 没经驻极处理, 直接出厂冒充 medical grade 熔喷布 情况.

无纺布 use （MFR, g/10min） generally in 30-35, production use 无纺布需 using/adopting MFI scope/range 31-44 high MFI polypropylene (PP), 而熔喷布 and more high MFI requirements product need using/adopting MFI scope/range in 45 above polypropylene (PP) material. high MFI polypropylene (PP) tool has relatively good flow property and relatively narrow molecular weight distribution, from can to more add stability 无纺布 product, combined 做口罩. MFR adjustment usually has below/following methods,

1） polymerization process through hydrogen gas adjustment control PP versus for molecular weight and versus for molecular weight distribution, this type of methods catalytic agent system and reaction conditions control and other made, need to versus for separation quality distribution narrow, MFR high PP comparison difficult, currently methods industrial application.

2） through toward polypropylene (PP) resin in add has machine oxidation material, formed for polypropylene (PP) control degradation function, from adjustment resin flow property. methods also by is can 控流变 technology, use has machine oxidation material will polypropylene (PP) separation in polymer/macromolecule fracture, make polypropylene (PP) resin molecular weight narrow, from very large degree upper high flow property, meanwhile basic 不改变材 material other property can. methods in process technology simple, reaction easy control features, is currently production ultra-high MFI polypropylene (PP) main/primary industrial application methods.

3） currently world upper many production PP resin company using/adopting ether inner to 体 齐格勒—— nano new type catalytic agent system, product MFR can 达300-1000, is pellets 形状（ usually is 珠粒） or fine pellets PP polymer, methods must using/adopting new type specialized catalytic agent.

也就 is 说, polypropylene (PP) need obtain high MFI, using/adopting has machine oxidation material adjustment is types simple can modified methods. 2,5-二甲基-2,5-二（叔丁基 oxygen 基）己烷(DTBPH) is used for polypropylene (PP) modified excellent additives, belongs to has machine oxidation material scope/range in important product. however, has machine oxidation material belongs to chemical product 范畴, easy oxidation 燃烧爆炸. more year front 开始, its development already to more made.

亚化 inquiry 获悉, inner has enterprise front year upper has machine oxidation material plant/unit method, is inquiry related rear, understanding type project for requirements its 严格, and has machine oxidation material in 国家不鼓励 development project inner, chemical industry conditions 苛刻, therefore 就打消 this method.

currently, inner has combined enterprise in production, 如Nouryon(诺 force company) and other, its in has machine oxidation material Model/Grade is Trigonox301. inner enterprise 说, is small enterprise small small 闹 模式 in production, and front 期 严格 environmental protection rear, more small enterprise already 停车.

普通口罩 use 无纺布 production using/adopting method （MeltBlowing）进行 made 备, method belongs to polymer pressure method non process, method production 无纺布 tool has 熔喷材 material more bending structure, can has 效进行 pellets material 滤, property is 35%, made formed 无纺布 product 也称熔喷无纺布.

process principle is use high speed hot gas for 模头喷 filament extrusion polymer melt fine 流进行牵伸, 由此形 formed ultra- fine fiber poly in 凝网帘 or upper, 依靠自身 bonding formed is non 织造布.

熔喷材 material is 靠自身 fiber hot formed, thick degree more thick method production 无纺布, fiber machine and 隔层交叉排列, formed 熔喷材 material more bending structure, this pellets material （ new 冠病毒 gas solvent 胶）才会 and fiber generate 碰撞而 by 滞留.

however used for, processing 熔喷布 made cost relatively high, production difficult degree relatively large, non generally enterprise can investment formed start production. type equipment large separation 都 自 Imported, Germany 莱芬, Italy STP, Japan N.K.K, USA Nordson and other. currently inner has separation equipment development related equipment, 如北京见奇 machine equipment manufacturing has company, 浙江朝隆 textile machine corporation has company and other. key/critical equipment 模头则 main/primary Japan company, 常州市晨 light machine manufacturing has company and other company production, currently also in 缺口.

业 inner toward 指出, front inner production 熔喷布 厂家并不 more. short time inner expand large production capacity in retardant 碍. has 熔喷布 equipment table/sheet 示, equipment cycle usually in 8 month left right, add upper 约2 month debugging time, short time inner difficult meet/satisfy increase demand. 况且熔喷 material production non viscous, equipment need machine renovation, renovation need time.

熔喷布 production also has 结束, medical grade production, in upper 述熔喷基础 upper 进行驻极处理. medical grade 口罩 滤 mechanism is expand dispersion, 截留, property 碰撞, heavy force drop and electrical 吸附, front types is material factors, is method production 无纺布自然 tool has features, need to medical grade production standards, let fiber belt/tape upper electrical 荷, use electrical new 冠病毒 in gas solvent 胶.

经 驻极处理 rear 无纺布, can in 不改变呼吸 retardant force front lower, achieve 95% 滤 property, has anti 病毒, to medical grade standards. 经驻极处理 high MFI 熔喷无纺布 raw materials generally by is medical grade high MFI 熔喷无纺布 raw materials.

静 electrical 吸附就 is through electrical fiber force achieve for new 冠病毒飞沫（ gas solvent 胶） 捕获. principle is let material surface more 开阔, for micro 粒 捕获 can force can 抢, electrical density increase, for pellets and 极化效应 more strong/high.

亚化 inquiry 获悉, 驻极体也早 already 出现断货 phenomenon, therefore in market upper less medical grade grade 熔喷布根本没经驻极处理就直接出厂, industry 乱象丛生.

21世纪以, many fiber material （如 polypropylene (PP) and fiber 素） by used for production medical grade 口罩, product can has 效 隔绝病毒 入侵. different fiber material made formed anti 护效果各不 same, anti 护效果 from most high to most low 依次递 decrease: polypropylene (PP), polyester filament, glass fiber and fiber fiber. polypropylene (PP) is most commonly used fiber, it tool has high hydrophobic water property and function, can let and between maintain drying 舒适.

尽 tube/pipe inner development frequency frequency 传出积极信号, however full 球, 疫情才 rigid rigid 开始. Japan, Korea, Italy, USA, and other 纷纷告急, large has 蔓延之势. 国土面积 and China 浙江省 versus Korea, 病情确诊人数 already ultra- 3500人, is 浙江确诊人数 3倍, 死亡人数达17例, 而浙江 is 1例. dilute degree ratio inner light 松, price in 情理之 in.

考虑国 inner anti and 复工复产 need, combined outer expand 张态势, supply will upper rise. also will has a large amount of new increase production capacity market, for/regarding main/primary raw materials polypropylene (PP), polypropylene (PP) specialized material demand still will large growth.
