熔喷布不 combined 格都认 is is equipment 不行, 喷头不行, is has more more causes? has how much true research?

熔喷布 from raw materials to formed product process:

polypropylene (PP) → modified equipment → modified polypropylene (PP) →熔喷 equipment →熔喷布→驻极处理→切割 formed 卷

熔喷布做达标 （ retardant rate 90+, 95+, 99+）, need step/link combined requirements. 任何一 step/link issues heavy effect/influence most formed product.

effect/influence 熔喷布 and other grade large factors:

1, polypropylene (PP) raw materials

2, process and equipment

3, 驻极处理

from this factors analysis, 方便熔喷布 production enterprise 排查. meanwhile introduction in material material production polypropylene (PP) material.

一, polypropylene (PP) raw materials

熔喷 material non generally polypropylene (PP), is tool has technology indicators modified polypropylene (PP). modified technology indicators is can will heavy effect/influence 熔喷布 quality.

for below/following 几点进行 analysis:

1, solvent degree

polypropylene (PP) homopolymer, filament use, solvent 指1500g/10min.

solvent to 1500g/10min can production nano grade fiber, retardant 挡病毒.

2, pellets melting point need reduce 至150-170°C between.

3, add 入驻极 masterbatch rear, 熔喷布经 驻极 plant/unit generate electrical property can.

4, polypropylene (PP) pellets modified rear, 经熔喷布 machine high temperature high pressure fiber fine long.

5, Raw Materials 自熔喷头喷出 流体 fiber 柔, tough, solid.

6, high temperature 杀菌消毒.

二, equipment

according to 示意图 raw materials through: extrusion machine →换网 device （ 滤 device ）→计 amount 泵→模头→ separation sheet/plate （辅助 hot 风）→喷 filament sheet/plate → formed plant/unit formed 熔喷布.

extrusion machine speed degree, amount parameters, excellent poor, hot gas temperature degree speed degree parameters, 模头角 degree, 风刀角 degree, material 接收距离, formed plant/unit lower parameters and other 共同决定 solvent quality.

this 里不做 more 展开, maintain 持续关注, rear more new machine debugging material.

in debugging machine front, 先确认 good Raw Materials. debugging above equipment, how how for, most can will or 者放弃. this type of phenomenon already in industry inner a large amount of 出现.

this is currently upper most small type machine, （专业名称: type filament machine, type formed machine ）, is large 众说黑 factory use equipment. its this is formed equipment, upper 世纪五十 year has, output/production volume is very high, front 熔喷布 production enterprise has use, in 实验室, testing in has application.

this machine 本身没 has plant/unit, formed 熔喷布之 rear 经 驻极 plant/unit 驻极, 熔喷布完 full can 达标. has 熔喷布 enterprise is negative production, also this large, this machine has necessary production.

导致 this machine method production combined 格 熔喷布 has below/following causes:

1, ring 境差, temperature degree wet degree, in dry gas and other.

2, equipment debugging to 位

3, 忽略驻极处理工序

4, Raw Materials combined 格

1-3 this causes, 熔喷厂 can solution, Raw Materials combined 格, debugging machine 师傅也不敢明说, and 金额太 large, is technology 钱, necessary resistant this large responsibility.

熔喷布厂 老 sheet/plate need 清楚, need machine can positive 常喷出布, is design defect, generally in good 情况. especially is material upper 都不错, light slip, is testing through, need Raw Materials. Raw Materials to 咱们 人 already more 手, 咱们根本看不 to rear 面 情况.

三, 驻极处理

1, 驻极处理 principle and effect/influence factors:

主流 application more is electrical electrical method for 熔喷布进行驻极处理, electrical electrical pressure, electrical time, electrical and ring wet degree for 驻极处理 效果 generate effect/influence. its in electrical electrical pressure for 驻极效果 effect/influence most obvious, electrical effect/influence in and other, electrical time effect/influence most small. in debugging machine need heavy 视.

ring wet degree for electrical generate and 流失都 has effect/influence, 熔喷布 enterprise need 时刻监测 workshop inner temperature degree and wet degree. increase versus equipment, make workshop temperature degree and wet degree maintain in scope/range inner.

2, raw materials for 驻极处理 effect/influence:

驻极处理熔喷布, 熔喷布必 must tool 备接收 electrical 荷保存 electrical features, 倘若没 has, 驻极处理根本没 use.

综 upper equipment, 驻极处理 can 看出, machine equipment debugging non important, debugging machine need raw materials combined 适 情况 lower debugging. large more raw materials, 没人敢直接指出 issues, procurement raw materials 熔喷布厂 maintain for 待, more need 盲目改变 machine parameters.

large 家一定 need 记住, has anti use 口罩一定 need has 熔喷布, 熔喷布必 must belt/tape electrical, 否则口罩没 has anti function.
